特開平９−９５１２４号公報JP-A-9-95124 特開２００６−２７４６１号公報JP 2006-27461 A

一般に、車両のフロントウィンドウパネルの直下に配置されるダッシュボードは、太陽光の入射に起因して高温になり易い。ダッシュボードの高温化は、車室内の温度上昇を招く。特に、夏場等で日射量が多く気温が高いときには、ダッシュボードの温度や車室内の温度は非常に高温となり、乗員に不快感を与える。このため、ダッシュボードの温度上昇を抑制することが望ましい。   In general, a dashboard disposed immediately below a front window panel of a vehicle is likely to become high temperature due to incidence of sunlight. The high temperature of the dashboard increases the temperature in the passenger compartment. In particular, when the amount of solar radiation is high and the temperature is high in summer, the temperature of the dashboard and the temperature of the passenger compartment become extremely high, which gives the passengers an uncomfortable feeling. For this reason, it is desirable to suppress the temperature rise of a dashboard.

しかし、上記特開平９−９５１２４号公報に記載された換気装置は、車室内を換気して車室内温度を低下させるものであり、ダッシュボードの温度を直接低下させるものではない。   However, the ventilator described in the above-mentioned JP-A-9-95124 ventilates the passenger compartment and lowers the passenger compartment temperature, and does not directly lower the dashboard temperature.

また、上記特開２００６−２７４６１号公報に記載された換気装置は、インパネの内部空間を換気することでインパネ表面の温度を低下させるものであり、太陽光の入射を受けて高温となるダッシュボードの上面を直接冷却するものではない。このため、ダッシュボードの温度を十分に低下させることができない可能性がある。   Moreover, the ventilation apparatus described in the said Unexamined-Japanese-Patent No. 2006-27461 reduces the temperature of the instrument panel surface by ventilating the internal space of an instrument panel, and is a dashboard which becomes high temperature in response to the incidence of sunlight. It does not directly cool the top surface of the glass. For this reason, there is a possibility that the temperature of the dashboard cannot be lowered sufficiently.

そこで、本発明は、ダッシュボードの温度上昇を効果的に抑制することが可能なダッシュボード冷却システムの提供を目的とする。   Therefore, an object of the present invention is to provide a dashboard cooling system capable of effectively suppressing a rise in dashboard temperature.

上記目的を達成すべく、本発明の第１の態様は、車両のダッシュボードの温度上昇を抑制するダッシュボード冷却システムであって、冷却路と循環路とポンプと通気路と切り替え手段と放熱器と空調作動検知手段と切り替え制御手段とを備える。 In order to achieve the above object, a first aspect of the present invention is a dashboard cooling system that suppresses temperature rise of a dashboard of a vehicle, and includes a cooling path, a circulation path, a pump, a ventilation path, a switching means, and a radiator. And air-conditioning operation detection means and switching control means .

冷却路は、冷却液が流入する流入口と流出する流出口とを有し、ダッシュボードの上面のほぼ全域の近傍を巡回する。循環路は、流入口と流出口とを連通する。ポンプは、循環路に設けられ、流出口から回収した冷却液を流入口へ循環供給する。通気路は、車外に開口する第１開口と分岐部とを連通する第１領域と、車外に開口する第２開口と分岐部とを連通する第２領域と、車室内に開口する第３開口と分岐部とを連通する第３領域とを有する。切り替え手段は、第２領域を閉塞する第１連通状態と第３領域を閉塞する第２連通状態とに選択的に設定可能である。放熱器は、循環路に設けられ且つ第１領域に配置されて内部を冷却液が流通するラジエータと、第１領域に設けられてラジエータに通風するファンとを有し、循環路を流通する冷却液を冷却する。空調作動検知手段は、車両に設けられて車室内へ空調風を供給する空調装置が作動しているか否かを検知する。切り替え制御手段は、空調装置が作動していると空調作動検知手段が検知した場合、切り替え手段を第２連通状態に設定し、空調装置が作動していないと空調作動検知手段が検知した場合、切り替え手段を第１連通状態に設定する。 The cooling path has an inflow port through which the cooling liquid flows in and an outflow port through which the cooling liquid flows, and circulates in the vicinity of almost the entire area of the upper surface of the dashboard. The circulation path connects the inlet and the outlet. The pump is provided in the circulation path and circulates and supplies the coolant recovered from the outlet to the inlet. The air passage includes a first region that communicates with the first opening that opens to the outside of the vehicle and the branch portion, a second region that communicates with the second opening that opens to the outside of the vehicle and the branch portion, and a third opening that opens into the vehicle interior. And a third region communicating with the branch portion. The switching means can be selectively set to a first communication state that closes the second region and a second communication state that closes the third region. The radiator has a radiator that is provided in the circulation path and is disposed in the first area and through which the coolant flows, and a fan that is provided in the first area and ventilates the radiator, and that circulates in the circulation path. Cool the liquid. The air conditioning operation detection means detects whether or not an air conditioner that is provided in the vehicle and supplies conditioned air to the passenger compartment is operating. The switching control means sets the switching means to the second communication state when the air-conditioning operation detecting means detects that the air-conditioning apparatus is operating, and when the air-conditioning operation detecting means detects that the air-conditioning apparatus is not operating, The switching means is set to the first communication state.

上記構成では、ポンプが駆動すると、冷却液は、流入口から冷却路へ流入してダッシュボードのほぼ全域の近傍を巡回して流出口から流出し、ラジエータの内部を流通して再び流入口から冷却路へ流入する。ファンが駆動すると、空気はラジエータを通過する。ダッシュボードの上面は、冷却路を流通する冷却液によって冷却され、ダッシュボードを冷却して昇温した冷却液は、ラジエータを通過する空気によって冷却される。ラジエータ及びファンは、通気路の第１領域に設けられる。切り替え手段が第１連通状態に設定されると、第２領域が閉塞され、通気路は第３開口及び第１開口を介して車室内と車外とに連通し、ファンが駆動すると、車室内の空気と車外の空気とが交換されて車室内が換気される。一方、切り替え手段が第２連通状態に設定されると、第３開口を介して車室内に連通する第３領域が閉塞され、通気路は車室内には連通せず、車室内は換気されない。   In the above configuration, when the pump is driven, the coolant flows into the cooling path from the inlet, circulates in the vicinity of almost the entire area of the dashboard, flows out from the outlet, flows through the radiator, and again from the inlet. It flows into the cooling path. When the fan is driven, air passes through the radiator. The upper surface of the dashboard is cooled by the coolant flowing through the cooling path, and the coolant that has been heated by cooling the dashboard is cooled by the air passing through the radiator. The radiator and the fan are provided in the first region of the ventilation path. When the switching means is set to the first communication state, the second region is closed, the air passage communicates with the vehicle interior and the exterior through the third opening and the first opening, and when the fan is driven, Air is exchanged with air outside the vehicle to ventilate the vehicle interior. On the other hand, when the switching means is set to the second communication state, the third region communicating with the vehicle interior through the third opening is closed, the air passage is not communicated with the vehicle interior, and the vehicle interior is not ventilated.

このように、太陽光の入射を受けて高温となるダッシュボードの上面を、比較的比熱の大きい冷却液を循環させて冷却するので、ダッシュボードの温度上昇を効果的に抑制することができる。また、ダッシュボードの温度上昇が抑制されるので、間接的に車室内の温度上昇も抑制することができる。また、車室内と車外とに連通可能な通気路に放熱器を設けているので、通気路を車室内と車外とに連通させることによってダッシュボードの冷却と車室内の換気とを同時に行うことができる。さらに、通気路の連通状態は切り替え手段の設定によって任意に変更できるので、環境条件や車両の状態等に応じて車室内の換気を行うか否かを選択することができる。
また、空調装置が作動すると、切り替え手段が第２連通状態に設定されるので、車室内の換気は行われない。従って、空調風が車外に流出せず、空調装置の過剰使用による電力の消費を抑制することができる。 As described above, since the upper surface of the dashboard that is heated by the incidence of sunlight is cooled by circulating the coolant having a relatively large specific heat, an increase in the temperature of the dashboard can be effectively suppressed. Moreover, since the temperature rise of a dashboard is suppressed, the temperature rise in a vehicle interior can also be suppressed indirectly. In addition, since the radiator is provided in the air passage that can communicate with the vehicle interior and the outside of the vehicle, the dashboard can be cooled and the vehicle interior can be ventilated simultaneously by communicating the air passage with the vehicle interior and the outside of the vehicle. it can. Furthermore, since the communication state of the air passage can be arbitrarily changed by the setting of the switching means, it is possible to select whether or not to ventilate the vehicle interior according to environmental conditions, vehicle conditions, and the like.
Further, when the air conditioner is activated, the switching means is set to the second communication state, so that the vehicle interior is not ventilated. Therefore, the conditioned air does not flow out of the vehicle, and power consumption due to excessive use of the air conditioner can be suppressed.

また、上記ダッシュボード冷却システムは、車室内温度検出センサと切り替え制御手段とを備えてもよい。車室内温度検出センサは、車室内の温度を検出する。切り替え制御手段は、車室内温度検出センサが検出した車室内の温度が所定温度以上の場合、切り替え手段を第１連通状態に設定し、検出した車室内の温度が所定温度未満の場合、切り替え手段を第２連通状態に設定する。   The dashboard cooling system may include a vehicle interior temperature detection sensor and a switching control unit. The vehicle interior temperature detection sensor detects the temperature in the vehicle interior. The switching control means sets the switching means to the first communication state when the temperature in the vehicle interior detected by the vehicle interior temperature detection sensor is equal to or higher than the predetermined temperature, and switches the switching means when the detected temperature in the vehicle interior is lower than the predetermined temperature. Is set to the second communication state.

上記構成では、車室内の温度が所定温度以上の場合には、切り替え手段が切り替え制御手段によって第１連通状態に設定されるので、ダッシュボードの冷却と車室内の換気とが同時に行われる。一方、車室内の温度が所定温度未満の場合には、切り替え手段が第２連通状態に設定されるので、ダッシュボードの冷却のみが行われる。このため、例えば、真夏の炎天下に駐車して車室内が高温となった場合には、ダッシュボードの冷却と車室内の換気とを同時に行い、乗員が乗車して車室内が適温となった場合には、ダッシュボードの冷却のみを行うことができる。   In the above configuration, when the temperature in the vehicle interior is equal to or higher than the predetermined temperature, the switching means is set to the first communication state by the switching control means, so that the cooling of the dashboard and the ventilation of the vehicle interior are performed simultaneously. On the other hand, when the temperature in the passenger compartment is lower than the predetermined temperature, the switching means is set to the second communication state, so that only the dashboard is cooled. For this reason, for example, when the vehicle interior becomes hot after parking in the midsummer sun, the dashboard is cooled and the vehicle interior is ventilated at the same time. Only the dashboard can be cooled.

本発明の第２の態様は、第１の態様の冷却路、循環路、ポンプ、通気路、切り換え手段、及び放熱器を備えたダッシュボード冷却システムであって、車室内の温度を検出する車室内温度検出センサと、車室内温度検出センサが検出した車室内の温度が所定温度以上の場合、切り替え手段を第１連通状態に設定し、車室内温度検出センサが検出した車室内の温度が所定温度未満の場合、切り替え手段を第２連通状態に設定する切り替え制御手段と、車両に設けられた車室内へ空調風を供給する空調装置が作動しているか否かを検知する空調作動検知手段を備える。切り替え制御手段は、空調装置が作動していると空調作動検知手段が検知した場合、車室内の温度に関わらず、切り替え手段を第２連通状態に設定する。 A second aspect of the present invention, the cooling path of the first aspect, the circulation path, a pump, a dashboard cooling system with ventilation channel, switching means, and a radiator, car for detecting the temperature in the passenger compartment When the temperature of the vehicle interior detected by the vehicle interior temperature detection sensor and the vehicle interior temperature detection sensor is equal to or higher than the predetermined temperature, the switching means is set to the first communication state, and the temperature of the vehicle interior detected by the vehicle interior temperature detection sensor is predetermined. A switching control means for setting the switching means to the second communication state when the temperature is lower, and an air conditioning operation detecting means for detecting whether or not the air conditioner for supplying the conditioned air to the passenger compartment provided in the vehicle is operating. with Ru. The switching control means sets the switching means to the second communication state when the air conditioning operation detecting means detects that the air conditioner is operating, regardless of the temperature in the passenger compartment.

上記構成では、空調装置が作動すると、車室内の温度が所定温度以上であっても、切り替え手段が第２連通状態に設定されるので、車室内の換気は行われない。従って、空調風が車外に流出せず、空調装置の過剰使用による電力の消費を抑制することができる。   In the above configuration, when the air conditioner is activated, the switching means is set to the second communication state even if the temperature in the passenger compartment is equal to or higher than the predetermined temperature, so that the passenger compartment is not ventilated. Therefore, the conditioned air does not flow out of the vehicle, and power consumption due to excessive use of the air conditioner can be suppressed.

また、上記第１の態様のダッシュボード冷却システムは、ファンを制御するファン制御手段を備えてもよい。ファンは、分岐部から第１開口へ向かって空気を流通させる正回転状態と第１開口から分岐部へ向かって空気を流通させる逆回転状態とに選択的に設定可能であり、ファン制御手段は、ファンを正回転状態と逆回転状態との少なくとも一方に選択的に設定する。 The dashboard cooling system according to the first aspect may include fan control means for controlling the fan. The fan can be selectively set to a forward rotation state in which air flows from the branching portion toward the first opening and a reverse rotation state in which air flows from the first opening toward the branching portion. The fan is selectively set to at least one of a forward rotation state and a reverse rotation state.

上記構成では、切り替え手段が切り替え制御手段によって第１連通状態に設定され、ファンがファン制御手段によって正回転状態に設定されると、車室内の空気がラジエータを通過して車外に排出される。すなわち、ダッシュボードの冷却と同時に車室内は排気方式で換気され、ラジエータ内を流通する昇温した冷却液は、主として車室内の空気によって冷却される。また、切り替え手段が第１連通状態に設定され、ファンが逆回転状態に設定されると、車外の空気がラジエータを通過して車室内に供給される。すなわち、ダッシュボードの冷却と同時に車室内は給気方式で換気され、昇温した冷却液は、主として車外の空気によって冷却される。一方、切り替え手段が第２連通状態に設定されると、ファンが正回転状態及び逆回転状態の何れに設定されていても、ダッシュボードの冷却のみが行われ、昇温した冷却液は、常に車外の空気によって冷却される。このように、通気路内の空気の流通方向はファンの設定によって任意に変更できるので、環境条件や車両の状態等に応じて、昇温した冷却液を冷却する空気を選択することができる。   In the above configuration, when the switching unit is set to the first communication state by the switching control unit and the fan is set to the normal rotation state by the fan control unit, the air in the vehicle interior passes through the radiator and is discharged outside the vehicle. In other words, the interior of the vehicle is ventilated by the exhaust system simultaneously with the cooling of the dashboard, and the heated coolant flowing through the radiator is mainly cooled by the air in the vehicle. Further, when the switching means is set to the first communication state and the fan is set to the reverse rotation state, air outside the vehicle passes through the radiator and is supplied into the vehicle interior. In other words, the interior of the vehicle is ventilated by the air supply method simultaneously with the cooling of the dashboard, and the raised coolant is mainly cooled by the air outside the vehicle. On the other hand, when the switching means is set to the second communication state, only the dashboard is cooled regardless of whether the fan is set to the forward rotation state or the reverse rotation state, Cooled by outside air. As described above, since the air flow direction in the air passage can be arbitrarily changed by the setting of the fan, it is possible to select the air that cools the raised coolant according to the environmental conditions, the state of the vehicle, and the like.

また、上記第１の態様のダッシュボード冷却システムは、車外の温度を検出する車外温度検出センサと、車室内の温度を検出する車室内温度検出センサとを備えてもよい。ファン制御手段は、車外温度検出センサが検出した車外の温度が第１所定温度以上で、且つ車室内温度検出センサが検出した車室内の温度と車外温度検出センサが検出した車外の温度との差が第２所定温度以上の場合、ファンを逆回転状態に設定する。 In addition, the dashboard cooling system according to the first aspect may include an outside temperature detection sensor that detects a temperature outside the vehicle and a vehicle interior temperature detection sensor that detects the temperature inside the vehicle . The fan control means is configured such that the temperature outside the vehicle detected by the vehicle outside temperature detection sensor is equal to or higher than the first predetermined temperature, and the difference between the temperature inside the vehicle detected by the vehicle interior temperature detection sensor and the temperature outside the vehicle detected by the vehicle outside temperature detection sensor. Is equal to or higher than the second predetermined temperature, the fan is set in the reverse rotation state.

上記構成では、車外の温度が第１所定温度以上で、且つ車室内の温度と車外の温度との差が第２所定温度以上の場合、ファンが逆回転状態に設定され、昇温した冷却液は主として車外の空気によって冷却される。このため、例えば、真夏の炎天下に長時間駐車して車室内が車外よりも相当高温になった場合には、昇温した冷却液が車室内の空気よりも低温の車外の空気によって冷却されるので、ダッシュボードの冷却効果を向上させることができる。   In the above configuration, when the temperature outside the vehicle is equal to or higher than the first predetermined temperature and the difference between the temperature inside the vehicle interior and the temperature outside the vehicle is equal to or higher than the second predetermined temperature, the fan is set in the reverse rotation state and the coolant is heated Is mainly cooled by air outside the vehicle. For this reason, for example, when the vehicle interior is parked for a long time under the hot summer heat and the interior of the vehicle becomes considerably hotter than the outside of the vehicle, the heated coolant is cooled by the air outside the vehicle that is cooler than the air inside the vehicle. Therefore, the cooling effect of the dashboard can be improved.

本発明の第３の態様は、第１の態様の冷却路、循環路、ポンプ、通気路、切り換え手段、及び放熱器を備えたダッシュボード冷却システムであって、ファンを制御するファン制御手段と、切り替え手段を制御する切り替え制御手段と、車室内の温度を検出する車室内温度検出センサと、ラジエータを通過した空気の温度を検出するラジエータ排気温度センサを備える。切り替え制御手段は、ファンが逆回転状態であって、車室内温度検出センサが検出した車室内の温度がラジエータ排気温度センサが検出したラジエータを通過した空気の温度以上の場合には、切り替え手段を第１連通状態に設定し、車室内温度検出センサが検出した車室内の温度がラジエータ排気温度センサが検出したラジエータを通過した空気の温度未満の場合には、切り替え手段を第２連通状態に設定する。 According to a third aspect of the present invention , there is provided a dashboard cooling system including the cooling path, the circulation path, the pump, the ventilation path, the switching means, and the radiator of the first aspect, and a fan control means for controlling a fan; , Ru comprising a switching control means for controlling the switching means, the vehicle interior temperature sensor for detecting the temperature of the passenger compartment, the radiator exhaust gas temperature sensor for detecting the temperature of air passing through the radiator. The switching control means is configured to switch the switching means when the temperature of the passenger compartment detected by the passenger compartment temperature detection sensor is equal to or higher than the temperature of the air passing through the radiator detected by the radiator exhaust temperature sensor. When the temperature in the vehicle compartment detected by the vehicle interior temperature detection sensor is lower than the temperature of the air that has passed through the radiator detected by the radiator exhaust temperature sensor , the switching means is set in the second communication state. To do.

上記構成では、ファンが逆回転状態に設定されて昇温した冷却液が車外の空気によって冷却される状態において、車室内の温度がラジエータを通過した空気（ラジエータ排気）の温度以上の場合には、切り替え手段が第１連通状態に設定され、ダッシュボードの冷却と同時に車室内は給気方式で換気され、車室内の温度がラジエータ排気の温度未満の場合には、切り替え手段が第２連通状態に設定され、ダッシュボードの冷却のみが行われる。このため、ラジエータ排気が車室内の空気よりも低温の場合には、ラジエータ排気を車室内に供給して直接的に車室内の温度上昇を抑制することができる。   In the above configuration, when the temperature of the vehicle interior is equal to or higher than the temperature of the air that has passed through the radiator (radiator exhaust) in a state where the cooling liquid heated by the fan set in the reverse rotation state is cooled by air outside the vehicle When the switching means is set to the first communication state, the interior of the vehicle is ventilated by the air supply method simultaneously with the cooling of the dashboard, and the switching means is in the second communication state when the temperature in the vehicle interior is lower than the temperature of the radiator exhaust. And only the dashboard is cooled. For this reason, when the radiator exhaust is at a lower temperature than the air in the passenger compartment, the radiator exhaust can be supplied into the passenger compartment to directly suppress the temperature rise in the passenger compartment.

また、上記第３の態様のダッシュボード冷却システムは、車両の始動を検知する車両始動検知手段を備えてもよい。切り替え制御手段は、ファン制御手段がファンを逆回転状態に設定し、且つ車両始動検知手段が車両の始動を検知した場合、ラジエータを通過した空気の温度に関わらず、切り替え手段を第２連通状態に設定する。 The dashboard cooling system according to the third aspect may include vehicle start detection means for detecting start of the vehicle. The switching control means sets the switching means in the second communication state when the fan control means sets the fan in the reverse rotation state and the vehicle start detection means detects the start of the vehicle regardless of the temperature of the air that has passed through the radiator. Set to.

上記構成では、車両が始動すると、ラジエータ排気の温度が車室内の温度未満であっても、切り替え手段が第２連通状態に設定され、車室内の換気は行われない。従って、比較的高温となるラジエータ排気が車室内に供給されないので、乗員はラジエータ排気が車室内を対流することによる不快感を覚えずに快適に乗車することができる。   In the above configuration, when the vehicle is started, even if the temperature of the radiator exhaust is lower than the temperature in the vehicle interior, the switching means is set to the second communication state, and the vehicle interior is not ventilated. Accordingly, since the radiator exhaust that is relatively hot is not supplied to the vehicle interior, the occupant can ride comfortably without feeling discomfort due to the convection of the radiator exhaust in the vehicle interior.

また、上記ダッシュボード冷却システムは、太陽光線を電力に変換する太陽電池を備えてもよい。この場合、ポンプ及びファンは、太陽電池からの電力によって直接駆動する。   The dashboard cooling system may include a solar cell that converts sunlight into electric power. In this case, the pump and fan are directly driven by power from the solar cell.

上記構成では、ポンプとファンは、日射量に比例して発電する太陽電池から直接電力が供給され駆動する。このため、ポンプ及びファンの駆動は日射量に比例して変化し、日射量が多いときには、冷却路に供給される冷却液の流量及びラジエータを通過する空気の風量は多くなり、ダッシュボードの冷却効果及び車室内の換気効果が向上する。従って、ポンプ及びファンの駆動を制御することなく、環境条件に適したダッシュボードの冷却及び車室内の換気を行うことができる。また、ポンプ及びファンの駆動を制御するためのセンサや制御装置が不要であるので、部品点数の増加を抑制し、システムを簡素化することができる。   In the above configuration, the pump and the fan are driven by being directly supplied with electric power from the solar cell that generates power in proportion to the amount of solar radiation. For this reason, the drive of the pump and fan changes in proportion to the amount of solar radiation. When the amount of solar radiation is large, the flow rate of the coolant supplied to the cooling path and the air volume of the air passing through the radiator increase. The effect and the ventilation effect in the passenger compartment are improved. Therefore, the dashboard can be cooled and the vehicle interior can be ventilated in accordance with the environmental conditions without controlling the driving of the pump and the fan. In addition, since a sensor and a control device for controlling the driving of the pump and the fan are unnecessary, an increase in the number of parts can be suppressed and the system can be simplified.

本発明によれば、ダッシュボードの上面を冷却液によって冷却するので、ダッシュボードの温度上昇を効果的に抑制することができる。   According to the present invention, since the upper surface of the dashboard is cooled by the coolant, the temperature rise of the dashboard can be effectively suppressed.

ポンプ２７は、ポンプモータ２８の回転軸に従動回転するインペラを有する遠心式ポンプであり、流入口２７ａから吸入した冷却液を、インペラの回転によって昇圧して流出口２７ｂから吐出する。ポンプモータ２８は、太陽電池１１から直接供給される電力によって駆動し、太陽電池１１の発電量は、日射量に比例して変化するため、ポンプ２７の吐水量は、日射量に比例して変化する。   The pump 27 is a centrifugal pump having an impeller that rotates following the rotation shaft of the pump motor 28, and the coolant sucked from the inlet 27 a is boosted by the rotation of the impeller and discharged from the outlet 27 b. The pump motor 28 is driven by the electric power directly supplied from the solar cell 11, and the amount of power generated by the solar cell 11 changes in proportion to the amount of solar radiation. Therefore, the amount of water discharged from the pump 27 changes in proportion to the amount of solar radiation. To do.

放熱器２９は、第１ダクト１４の内部の第１領域１６に配置され、ブラケット（図示省略）を介して第１ダクト１４の内周面に支持される。ラジエータ３０は、チューブとフィンとで構成されるコア部と、コア部の両端に位置する２つのタンクとを有する。２つのタンクの一方と他方とには、それぞれ流入口３０ａと流出口３０ｂとが設けられ、冷却液は、一方のタンクの流入口３０ａから流入し、コア部のチューブを通過して、他方のタンクの流出口３０ｂから流出する。   The radiator 29 is disposed in the first region 16 inside the first duct 14 and is supported on the inner peripheral surface of the first duct 14 via a bracket (not shown). The radiator 30 has a core part composed of tubes and fins, and two tanks located at both ends of the core part. One and the other of the two tanks are respectively provided with an inlet 30a and an outlet 30b, and the coolant flows from the inlet 30a of one tank, passes through the tube of the core portion, and passes through the other tank. It flows out from the outlet 30b of the tank.

ファン３１は、ファンモータ３２の回転軸に従動して回転する。ファン３１が回転すると、第２開口１８又は第３開口２１から通気路内に空気が流入し、流入した空気がラジエータ３０を通過して第１開口１５から車外へ流出する。ファンモータ３２は、太陽電池１１から直接供給される電力によって駆動し、太陽電池１１の発電量は、日射量に比例して変化するため、ファン３１の送風量は、日射量に比例して変化する。   The fan 31 rotates following the rotation shaft of the fan motor 32. When the fan 31 rotates, air flows into the air passage from the second opening 18 or the third opening 21, and the air that has flowed in passes through the radiator 30 and flows out of the vehicle from the first opening 15. The fan motor 32 is driven by the electric power directly supplied from the solar battery 11, and the amount of power generated by the solar battery 11 changes in proportion to the amount of solar radiation. Therefore, the amount of air blown by the fan 31 changes in proportion to the amount of solar radiation. To do.

車室内温度検出センサ３３は、車室３内に設けられ、所定時間毎に車室３内の温度を検出し、コントローラ３４に出力する。   The vehicle interior temperature detection sensor 33 is provided in the vehicle interior 3, detects the temperature in the vehicle interior 3 every predetermined time, and outputs it to the controller 34.

コントローラ３４には、車室内温度検出センサ３３からの車室内温度信号とエアコンスイッチ３５からのオン／オフ信号とが入力する。コントローラ３４は、車室内温度検出センサ３３が検出する車室３内の温度と、エアコンの作動状態（エアコンスイッチ３５から入力するオン／オフ信号の状態）とに基づいて、弁駆動モータ２６の駆動を制御して切り替え弁２５の状態を適宜変更する。コントローラ３４による弁駆動モータ２６の駆動制御は、弁駆動モータ２６の作動のオン／オフと回転方向の変更とを含む。コントローラ３４は、車室３内の温度が所定温度以上で且つエアコンがオフの場合には、切り替え弁２５を第１位置に設定し、車室３内の温度が所定温度未満の場合又はエアコンがオンの場合には、切り替え弁２５を第２位置に設定する。すなわち、コントローラ３４は、車室３内の温度とエアコンの作動状態とに応じて切り替え弁２５を第１位置又は第２位置に設定する切り替え制御手段として機能し、エアコンスイッチ３５は、エアコンが作動しているか否かを検知する空調作動検出手段として機能する。   The controller 34 receives a vehicle interior temperature signal from the vehicle interior temperature detection sensor 33 and an on / off signal from the air conditioner switch 35. The controller 34 drives the valve drive motor 26 based on the temperature in the passenger compartment 3 detected by the passenger compartment temperature detection sensor 33 and the operating state of the air conditioner (the state of the on / off signal input from the air conditioner switch 35). To change the state of the switching valve 25 as appropriate. The drive control of the valve drive motor 26 by the controller 34 includes turning on / off the operation of the valve drive motor 26 and changing the rotation direction. The controller 34 sets the switching valve 25 to the first position when the temperature in the passenger compartment 3 is equal to or higher than the predetermined temperature and the air conditioner is off, and when the temperature in the passenger compartment 3 is lower than the predetermined temperature, When it is on, the switching valve 25 is set to the second position. That is, the controller 34 functions as switching control means for setting the switching valve 25 to the first position or the second position according to the temperature in the passenger compartment 3 and the operating state of the air conditioner, and the air conditioner switch 35 operates the air conditioner. It functions as air-conditioning operation detection means for detecting whether or not it is.

上記のように構成されたダッシュボード冷却システム１では、駆動中のポンプ２７から吐出された冷却液は、第１管路１０ａ→冷却パネル６の冷却パイプ７→第２管路１０ｂ→ラジエータ３０→第３管路１０ｃ→ポンプ２７の順に循環し、ダッシュボード４の上面は、冷却パイプ７を流通する冷却液によって冷却される。   In the dashboard cooling system 1 configured as described above, the coolant discharged from the pump 27 being driven flows from the first pipe 10a → the cooling pipe 7 of the cooling panel 6 → the second pipe 10b → the radiator 30 → It circulates in order of the 3rd pipe line 10c-> pump 27, and the upper surface of the dashboard 4 is cooled by the cooling fluid which distribute | circulates the cooling pipe 7. FIG.

また、車室３内の温度が所定温度以上で且つエアコンがオフの場合には、切り替え弁２５が第１位置に設定されるので、車室３内の空気は、ファン３１の回転によって第３開口２１から通気路内に流入し、第１開口１５から車外に排出される。これにより、ダッシュボード４を冷却して昇温した冷却液は、主として車室３内の空気によって冷却され、車室３内は排気方式で換気される。一方、車室３内の温度が所定温度未満の場合又はエアコンがオンの場合には、切り替え弁２５が第２位置に設定されるので、車外の空気は、ファン３１の回転によって第２開口１８から通気路内に流入し、第１開口１５から車外に排出される。これにより、昇温した冷却液は、常に車外の空気によって冷却され、車室３内は換気されない。   Further, when the temperature in the passenger compartment 3 is equal to or higher than the predetermined temperature and the air conditioner is off, the switching valve 25 is set to the first position. The air flows into the air passage from the opening 21 and is discharged out of the vehicle through the first opening 15. As a result, the coolant that has been heated by cooling the dashboard 4 is mainly cooled by the air in the passenger compartment 3, and the interior of the passenger compartment 3 is ventilated by an exhaust system. On the other hand, when the temperature in the passenger compartment 3 is lower than the predetermined temperature or when the air conditioner is on, the switching valve 25 is set to the second position. From the first opening 15 to the outside of the vehicle. Thus, the heated coolant is always cooled by the air outside the vehicle, and the interior of the passenger compartment 3 is not ventilated.

また、ポンプモータ２８とファンモータ３２とは、太陽電池１１から直接供給される電力によってそれぞれ駆動し、ポンプ２７の吐水量及びファン３１の送風量は、日射量に比例してそれぞれ変化する。このため、日射しが強く日射量が多い環境下であるほど、冷却パイプ７に流入する冷却液の流量及びラジエータ３０を通過する空気の風量が増大し、ダッシュボード４の冷却効果及び車室３内の換気効果が向上する。   Moreover, the pump motor 28 and the fan motor 32 are each driven by the electric power directly supplied from the solar battery 11, and the water discharge amount of the pump 27 and the air blowing amount of the fan 31 change in proportion to the amount of solar radiation. For this reason, the more the solar radiation is and the greater the amount of solar radiation is, the more the flow rate of the coolant flowing into the cooling pipe 7 and the air volume of the air passing through the radiator 30 are increased. The ventilation effect is improved.

このように、本実施形態のダッシュボード冷却システム１によれば、太陽光の入射を受けて高温となるダッシュボード４の上面を、比較的比熱の大きい冷却液を循環させて冷却するので、ダッシュボード４の温度上昇を効果的に抑制することができ、ダッシュボード４の高温化に伴う車室３内の温度上昇を抑制することができる。   As described above, according to the dashboard cooling system 1 of the present embodiment, the upper surface of the dashboard 4 that is heated by the incidence of sunlight is cooled by circulating the coolant having a relatively large specific heat. The temperature increase of the board 4 can be effectively suppressed, and the temperature increase in the passenger compartment 3 accompanying the high temperature of the dashboard 4 can be suppressed.

また、ダッシュボード４の内部構造を変更することなく、冷却パネル６をダッシュボード４の上面に設けているため、既存の車両に対しても本システムを容易に適用することができる。   Further, since the cooling panel 6 is provided on the upper surface of the dashboard 4 without changing the internal structure of the dashboard 4, the present system can be easily applied to an existing vehicle.

また、放熱器２９は、車室３内と車外とを連通する第１連通状態に設定可能な通気路に配置されているので、第１連通状態では、ダッシュボード４の冷却と同時に、車室３内の空気を車外に排出して車室３内を換気することができる。   In addition, since the radiator 29 is disposed in the air passage that can be set in the first communication state that allows the inside of the passenger compartment 3 to communicate with the outside of the vehicle, in the first communication state, simultaneously with the cooling of the dashboard 4, the passenger compartment. The inside of the vehicle compartment 3 can be ventilated by discharging the air in the vehicle 3 to the outside of the vehicle.

また、車室３内が所定温度以上で且つエアコンがオフの場合には、車室３内は換気され、車室３内の温度が所定温度未満の場合又はエアコンがオンの場合には、車室３内は換気されない。このため、例えば、真夏の炎天下に駐車して車室３内が高温となった場合には、ダッシュボード４の冷却と車室３内の換気とが同時に行われて車室３内の温度上昇が抑制されるので、乗車時の乗員の不快感を低減し、運転開始直後におけるエアコンの過剰使用による電力の消費を抑制することができる。一方、車室３内が適温の場合や乗員がエアコンを作動させる場合には、ダッシュボード４の冷却のみが行われ車室３内の空気が車外に流出しないので、車室３内を快適な状態に維持することができ、また、エアコンの過剰使用による電力の消費を抑制することができる。   Further, when the interior of the passenger compartment 3 is above a predetermined temperature and the air conditioner is off, the interior of the passenger compartment 3 is ventilated, and when the temperature inside the passenger compartment 3 is lower than the predetermined temperature or the air conditioner is on, The room 3 is not ventilated. Therefore, for example, when the vehicle interior 3 is parked under the hot summer sun and the interior of the passenger compartment 3 becomes hot, the dashboard 4 is cooled and the interior of the passenger compartment 3 is ventilated at the same time. Therefore, it is possible to reduce the discomfort of the passengers at the time of boarding and to suppress power consumption due to excessive use of the air conditioner immediately after the start of driving. On the other hand, when the interior of the passenger compartment 3 is at a suitable temperature or when the occupant operates the air conditioner, only the dashboard 4 is cooled and the air in the passenger compartment 3 does not flow out of the passenger compartment. It can be maintained in a state, and power consumption due to excessive use of the air conditioner can be suppressed.

また、ポンプ２７及びファン３１は、日射量に比例して発電する太陽電池１１から直接電力が供給されて駆動するポンプモータ２８及びファンモータ３２によって駆動されるので、ポンプ２７及びファン３１の駆動を制御することなく、環境条件に適したダッシュボード４の冷却及び車室３内の換気を行うことができる。また、ポンプ２７及びファン３１の駆動を制御するためのセンサや制御装置が不要であるので、部品点数の増加を抑制し、システムを簡素化することができる。   The pump 27 and the fan 31 are driven by the pump motor 28 and the fan motor 32 that are driven by being directly supplied with power from the solar battery 11 that generates power in proportion to the amount of solar radiation. Without control, the dashboard 4 can be cooled and the interior of the passenger compartment 3 can be ventilated in accordance with environmental conditions. In addition, since a sensor and a control device for controlling the driving of the pump 27 and the fan 31 are not required, an increase in the number of parts can be suppressed and the system can be simplified.

また、切り替え弁２５、ポンプ２７及びファン３１は、太陽電池１１からの電力のみで駆動されるので、ダッシュボード冷却システム１の作動は車載バッテリに対して影響を与えない。   Moreover, since the switching valve 25, the pump 27, and the fan 31 are driven only by the electric power from the solar cell 11, the operation of the dashboard cooling system 1 does not affect the in-vehicle battery.

なお、ダッシュボード４を冷却する方法は、上記に限定されない。例えば、ダッシュボード４の上面のパネル内側に冷却液が流通するパイプを直接取り付けてもよく、ダッシュボード４の上面のパネルに、仕切板等で冷却液が流通する流路を形成して、冷却液を流通させてもよい。   The method for cooling the dashboard 4 is not limited to the above. For example, a pipe through which the coolant flows may be directly attached to the inside of the upper panel of the dashboard 4. A cooling channel may be formed in the upper panel of the dashboard 4 by forming a flow path through which the coolant flows. A liquid may be circulated.

また、切り替え弁２５の状態は、車室３内の温度とエアコンの作動状態との双方に基づいて設定されることに限定されず、何れか一方や他の判断基準に基づいて設定されてもよく、乗員の意思によって設定されてもよい。切り替え弁２５の状態を乗員の意思によって設定する場合、乗員からの操作を受け付ける専用のスイッチを車室３内等に設け、当該スイッチの操作に応じてコントローラ３４が切り替え弁２５の状態を切り替える方法や、切り替え弁２５に機械式レバーを取り付け、乗員が当該レバーを直接操作することによって切り替え弁２５の状態が切り替わる方法等が適用可能である。   Further, the state of the switching valve 25 is not limited to being set based on both the temperature in the passenger compartment 3 and the operating state of the air conditioner, and may be set based on any one or other criteria. Well, it may be set according to the will of the passenger. When setting the state of the switching valve 25 according to the occupant's intention, a method of providing a dedicated switch for receiving an operation from the occupant in the passenger compartment 3 or the like, and the controller 34 switching the state of the switching valve 25 according to the operation of the switch. Alternatively, a method of switching the state of the switching valve 25 by attaching a mechanical lever to the switching valve 25 and directly operating the lever by an occupant can be applied.

また、車室内温度検出センサ３３とコントローラ３４とに代えて、サーモスタットを車室３内に設け、サーモスタットからのオン／オフ信号に応じて弁駆動モータ２６の回転方向が制御されて切り替え弁２５の状態が切り替わってもよい。   Further, instead of the vehicle interior temperature detection sensor 33 and the controller 34, a thermostat is provided in the vehicle interior 3, and the direction of rotation of the valve drive motor 26 is controlled in accordance with an on / off signal from the thermostat, and the switching valve 25. The state may be switched.

また、太陽電池１１の配置場所は、上記に限定されず、例えば、ダッシュボード４上の冷却パネル６の上面であってもよい。太陽電池１１は、自身の温度が低いほど発電効率が向上することから、太陽電池１１を冷却パネル６の第１冷却プレート９ａの上面に載置し、第１冷却プレート９ａを、第２冷却プレート９ｂと同様に熱伝導率が高い樹脂等で形成することによって、太陽電池１１の発電効率を向上させることができる。   Moreover, the arrangement | positioning location of the solar cell 11 is not limited above, For example, the upper surface of the cooling panel 6 on the dashboard 4 may be sufficient. Since the solar cell 11 improves the power generation efficiency as its own temperature is lower, the solar cell 11 is placed on the upper surface of the first cooling plate 9a of the cooling panel 6, and the first cooling plate 9a is replaced with the second cooling plate. As with 9b, the power generation efficiency of the solar cell 11 can be improved by forming it with a resin having a high thermal conductivity.

また、切り替え弁２５の状態をエアシリンダや油圧シリンダ等によって変更してもよい。   Further, the state of the switching valve 25 may be changed by an air cylinder, a hydraulic cylinder, or the like.

次に、本発明の第２実施形態のダッシュボード冷却システムについて図面を参照して説明する。本実施形態は、ファン３１の回転方向を制御して通気路内の空気の流通方向を変更する点において上記第１実施形態と相違する。なお、上記第１実施形態と同様の構成には、同一の符号を付してその詳細な説明を省略する。図４は、本実施形態のダッシュボード冷却システムの構成図である。   Next, a dashboard cooling system according to a second embodiment of the present invention will be described with reference to the drawings. The present embodiment is different from the first embodiment in that the rotation direction of the fan 31 is controlled to change the air flow direction in the air passage. In addition, the same code | symbol is attached | subjected to the structure similar to the said 1st Embodiment, and the detailed description is abbreviate | omitted. FIG. 4 is a configuration diagram of the dashboard cooling system of the present embodiment.

図４に示すように、本実施形態のダッシュボード冷却システムは、車外温度検出センサ３６と、ラジエータ排気温度検出センサ３７とを備える。車室３内には、乗員からの操作に応じて車両２を始動及び停止させるイグニッションスイッチ３８が配置されている。   As shown in FIG. 4, the dashboard cooling system of the present embodiment includes an outside temperature detection sensor 36 and a radiator exhaust temperature detection sensor 37. An ignition switch 38 for starting and stopping the vehicle 2 in accordance with an operation from a passenger is disposed in the passenger compartment 3.

車外温度検出センサ３６は、車両２の外部に設けられ、所定時間毎に車外の温度を検出し、コントローラ３４に出力する。   The vehicle outside temperature detection sensor 36 is provided outside the vehicle 2, detects the temperature outside the vehicle every predetermined time, and outputs it to the controller 34.

ラジエータ排気温度検出センサ３７は、通気路内のラジエータ３０と切り替え弁２５との間に設けられ、所定時間毎にラジエータ３０を通過した空気（ラジエータ排気）の温度を検出し、コントローラ３４に出力する。   The radiator exhaust temperature detection sensor 37 is provided between the radiator 30 and the switching valve 25 in the air passage, detects the temperature of the air (radiator exhaust) that has passed through the radiator 30 every predetermined time, and outputs the detected temperature to the controller 34. .

ファン３１は、ファンモータ３２によって正回転状態と逆回転状態とに選択的に設定される。ファン３１が正回転状態で回転すると、第２開口１８又は第３開口２１から通気路内に空気が流入し、流入した空気がラジエータ３０を通過して第１開口１５から車外へ流出する。一方、ファン３１が逆回転状態で回転すると、第１開口１５から通気路内に車外の空気が流入し、流入した空気がラジエータ３０を通過して第２開口１８又は第３開口２１から流出する。   The fan 31 is selectively set to a normal rotation state and a reverse rotation state by a fan motor 32. When the fan 31 rotates in the forward rotation state, air flows into the air passage from the second opening 18 or the third opening 21, and the air that has flowed in passes through the radiator 30 and flows out of the vehicle from the first opening 15. On the other hand, when the fan 31 rotates in the reverse rotation state, air outside the vehicle flows into the air passage from the first opening 15, and the air that has flowed in passes through the radiator 30 and flows out from the second opening 18 or the third opening 21. .

コントローラ３４には、車室内温度検出センサ３３、車外温度検出センサ３６及びラジエータ排気温度センサ３７からの各温度信号と、イグニッションスイッチ３８及びエアコンスイッチ３５からのオン／オフ信号とが入力する。コントローラ３４は、車室内温度検出センサ３３が検出する車室３内の温度と、車外温度検出センサ３６が検出する車外の温度とに基づいて、ファンモータ３２の回転方向を制御してファン３１の回転状態を適宜変更する。また、車室内温度検出センサ３３が検出する車室３内の温度と、ラジエータ排気温度検出センサ３７が検出するラジエータ排気の温度と、車両２の始動状態（イグニッションスイッチ３８から入力するオン／オフ信号の状態）と、エアコンの作動状態（エアコンスイッチ３５から入力するオン／オフ信号の状態）とに基づいて、弁駆動モータ２６の駆動を制御して切り替え弁２５の状態を適宜変更する。   The controller 34 receives temperature signals from the vehicle interior temperature detection sensor 33, the vehicle exterior temperature detection sensor 36 and the radiator exhaust temperature sensor 37, and ON / OFF signals from the ignition switch 38 and the air conditioner switch 35. The controller 34 controls the rotation direction of the fan motor 32 based on the temperature inside the vehicle compartment 3 detected by the vehicle interior temperature detection sensor 33 and the temperature outside the vehicle detected by the vehicle outside temperature detection sensor 36 to control the fan 31. Change the rotation state as appropriate. Further, the temperature in the vehicle compartment 3 detected by the vehicle interior temperature detection sensor 33, the temperature of the radiator exhaust detected by the radiator exhaust temperature detection sensor 37, and the start state of the vehicle 2 (ON / OFF signal input from the ignition switch 38) ) And the operating state of the air conditioner (the state of the on / off signal input from the air conditioner switch 35), the drive of the valve drive motor 26 is controlled to change the state of the switching valve 25 as appropriate.

コントローラ３４は、車外の温度が第１所定温度未満の場合又は車室３内の温度と車外の温度との差が第２所定温度未満の場合には、ファン３１を正回転状態に設定し、車外の温度が第１所定温度以上で且つ車室３内の温度と車外の温度との差が第２所定温度以上の場合には、ファン３１を逆回転状態に設定する。ファン３１を正回転状態に設定したとき、コントローラ３４は、車室３内の温度が所定温度以上で且つエアコンがオフの場合には、切り替え弁２５を第１位置に設定し、車室３内の温度が所定温度未満の場合又はエアコンがオンの場合には、切り替え弁２５を第２位置に設定する。一方、ファン３１を逆回転状態に設定したとき、コントローラ３４は、車室３内の温度がラジエータ排気の温度以上で且つ車両２が始動していない場合には、切り替え弁２５を第１位置に設定し、車室３内の温度がラジエータ排気の温度未満の場合又は車両２が始動した場合には、切り替え弁２５を第２位置に設定する。すなわち、コントローラ３４は、車室３内の温度と車外の温度とに応じてファン３１を正回転状態又は逆回転状態に設定するファン制御手段、及び車室３内の温度とラジエータ排気温度と車両２の始動状態とエアコンの作動状態とに応じて切り替え弁２５を第１位置又は第２位置に設定する切り替え制御手段として機能する。また、イグニッションスイッチ３８は、車両２の始動を検知する車両始動検知手段として機能する。   When the temperature outside the vehicle is lower than the first predetermined temperature or when the difference between the temperature inside the passenger compartment 3 and the temperature outside the vehicle is lower than the second predetermined temperature, the controller 34 sets the fan 31 in the normal rotation state. When the temperature outside the vehicle is equal to or higher than the first predetermined temperature and the difference between the temperature inside the passenger compartment 3 and the temperature outside the vehicle is equal to or higher than the second predetermined temperature, the fan 31 is set in the reverse rotation state. When the fan 31 is set in the forward rotation state, the controller 34 sets the switching valve 25 to the first position when the temperature in the passenger compartment 3 is equal to or higher than a predetermined temperature and the air conditioner is off. When the temperature is lower than the predetermined temperature or when the air conditioner is on, the switching valve 25 is set to the second position. On the other hand, when the fan 31 is set in the reverse rotation state, the controller 34 sets the switching valve 25 to the first position when the temperature in the passenger compartment 3 is equal to or higher than the temperature of the radiator exhaust and the vehicle 2 is not started. When the temperature inside the passenger compartment 3 is lower than the temperature of the radiator exhaust or when the vehicle 2 is started, the switching valve 25 is set to the second position. That is, the controller 34 sets fan control means for setting the fan 31 to the forward rotation state or the reverse rotation state according to the temperature inside the vehicle compartment 3 and the temperature outside the vehicle, and the temperature inside the vehicle compartment 3, the radiator exhaust temperature, and the vehicle The switching valve 25 functions as switching control means for setting the switching valve 25 to the first position or the second position in accordance with the starting state 2 and the operating state of the air conditioner. Further, the ignition switch 38 functions as a vehicle start detection unit that detects the start of the vehicle 2.

上記のように構成されたダッシュボード冷却システムでは、車外の温度が第１所定温度未満の場合又は車室３内の温度と車外の温度との差が第２所定温度未満の場合には、ファン３１が正回転状態に設定される。ファン３１が正回転状態に設定され、車室３内の温度が所定温度以上で且つエアコンがオフの場合には、切り替え弁２５が第１位置に設定されるので、車室３内の空気は、ファン３１の回転によって第３開口２１から通気路内に流入し、第１開口１５から車外に排出される。これにより、昇温した冷却液は、主として車室３内の空気によって冷却され、車室３内は排気方式で換気される。また、ファン３１が正回転状態に設定され、車室３内の温度が所定温度未満の場合又はエアコンがオンの場合には、切り替え弁２５が第２位置に設定されるので、車外の空気は、ファン３１の回転によって第２開口１８から通気路内に流入し、第１開口１５から車外に排出される。これにより、昇温した冷却液は、常に車外の空気によって冷却され、車室３内は換気されない。   In the dashboard cooling system configured as described above, when the temperature outside the vehicle is lower than the first predetermined temperature or when the difference between the temperature in the passenger compartment 3 and the temperature outside the vehicle is lower than the second predetermined temperature, the fan 31 is set to the forward rotation state. When the fan 31 is set to the normal rotation state, the temperature in the passenger compartment 3 is equal to or higher than the predetermined temperature, and the air conditioner is off, the switching valve 25 is set to the first position. As the fan 31 rotates, it flows into the air passage from the third opening 21 and is discharged out of the vehicle through the first opening 15. As a result, the heated coolant is cooled mainly by the air in the passenger compartment 3, and the passenger compartment 3 is ventilated by an exhaust system. Further, when the fan 31 is set to the normal rotation state and the temperature in the passenger compartment 3 is lower than the predetermined temperature or the air conditioner is on, the switching valve 25 is set to the second position, so that the air outside the vehicle is As the fan 31 rotates, the air flows into the air passage from the second opening 18 and is discharged out of the vehicle through the first opening 15. Thus, the heated coolant is always cooled by the air outside the vehicle, and the interior of the passenger compartment 3 is not ventilated.

一方、車外の温度が第１所定温度以上で且つ車室３内の温度と車外の温度との差が第２所定温度以上の場合には、ファン３１が逆回転状態に設定される。ファン３１が逆回転状態に設定され、車室３内の温度がラジエータ排気の温度以上で且つ車両２が始動していない場合には、切り替え弁２５が第１位置に設定されるので、車外の空気は、ファン３１の回転によって第１開口１５から通気路内に流入し、第３開口２１から車室３内に供給される。これにより、昇温した冷却液は、主として車外の空気によって冷却され、車室３内は給気方式で換気される。また、ファン３１が逆回転状態に設定され、車室３内の温度がラジエータ排気の温度未満の場合又は車両２が始動した場合には、切り替え弁２５が第２位置に設定されるので、車外の空気は、ファン３１の回転によって第１開口１５から通気路内に流入し、第２開口１８から車外に排出される。これにより、昇温した冷却液は、常に車外の空気によって冷却され、車室３内は換気されない。   On the other hand, when the temperature outside the vehicle is equal to or higher than the first predetermined temperature and the difference between the temperature inside the passenger compartment 3 and the temperature outside the vehicle is equal to or higher than the second predetermined temperature, the fan 31 is set in the reverse rotation state. When the fan 31 is set in the reverse rotation state, the temperature in the passenger compartment 3 is equal to or higher than the temperature of the radiator exhaust, and the vehicle 2 is not started, the switching valve 25 is set to the first position. The air flows into the air passage from the first opening 15 by the rotation of the fan 31, and is supplied into the passenger compartment 3 from the third opening 21. Thus, the heated coolant is cooled mainly by the air outside the vehicle, and the interior of the passenger compartment 3 is ventilated by the air supply method. Further, when the fan 31 is set in the reverse rotation state and the temperature in the passenger compartment 3 is lower than the temperature of the radiator exhaust or when the vehicle 2 is started, the switching valve 25 is set at the second position, so that the outside of the vehicle This air flows into the air passage from the first opening 15 by the rotation of the fan 31 and is discharged out of the vehicle through the second opening 18. Thus, the heated coolant is always cooled by the air outside the vehicle, and the interior of the passenger compartment 3 is not ventilated.

このように、本実施形態のダッシュボード冷却システムによれば、ファン３１の回転方向を制御して通気路内の空気の流通方向を変更するので、昇温した冷却液を冷却する空気を選択することができる。   As described above, according to the dashboard cooling system of this embodiment, the rotation direction of the fan 31 is controlled to change the flow direction of the air in the air passage, so the air for cooling the heated coolant is selected. be able to.

また、車外の温度が第１所定温度以上で且つ車室３内の温度と車外の温度との差が第２所定温度以上の場合には、昇温した冷却液は車外の空気によって冷却される。このため、例えば、真夏の炎天下に長時間駐車して車室３内が車外よりも相当高温になった場合には、昇温した冷却液が車室３内の空気よりも低温の車外の空気によって冷却されるので、ダッシュボード４の冷却効果を向上させることができる。   When the temperature outside the vehicle is equal to or higher than the first predetermined temperature and the difference between the temperature inside the passenger compartment 3 and the temperature outside the vehicle is equal to or higher than the second predetermined temperature, the raised coolant is cooled by the air outside the vehicle. . For this reason, for example, when the vehicle interior 3 is parked for a long time under the hot summer sun and the interior of the passenger compartment 3 becomes considerably hotter than the exterior of the vehicle, the temperature of the coolant outside the vehicle is lower than the air in the interior of the passenger compartment 3. Therefore, the cooling effect of the dashboard 4 can be improved.

また、昇温した冷却液が車外の空気によって冷却される状態で、車室３内の温度がラジエータ排気温度以上で且つ車両２が始動していない場合には、車室３内の空気よりも低温のラジエータ排気が車室３内に供給されるので、車室３内を低温化させることができ、車室３内の温度上昇を効果的に抑制することができる。   When the temperature of the interior of the passenger compartment 3 is equal to or higher than the radiator exhaust temperature and the vehicle 2 is not started in a state where the heated coolant is cooled by the air outside the vehicle, the temperature of the coolant is higher than that of the air in the passenger compartment 3. Since the low-temperature radiator exhaust is supplied into the passenger compartment 3, the interior of the passenger compartment 3 can be lowered, and the temperature rise in the passenger compartment 3 can be effectively suppressed.

また、車両２が始動すると、車室３内へのラジエータ排気の供給は停止するので、乗員はラジエータ排気が車室３内を対流することによる不快感を覚えずに快適に乗車することができる。   Further, when the vehicle 2 is started, the supply of the radiator exhaust into the passenger compartment 3 is stopped, so that the passenger can ride comfortably without feeling uncomfortable due to the convection of the radiator exhaust inside the passenger compartment 3. .

なお、上記実施形態は本発明の一例であり、本発明を逸脱しない範囲において変更可能である。   In addition, the said embodiment is an example of this invention and can be changed in the range which does not deviate from this invention.

本発明は、車両のダッシュボード及び車室内の温度上昇の抑制に有効である。   INDUSTRIAL APPLICABILITY The present invention is effective for suppressing a temperature rise in a vehicle dashboard and a passenger compartment.
