Description

本発明は、直射日光により上昇した車室内温度をヒートパイプを介して大気中に放熱して低減するようにした車室内温度降下装置に関する。   The present invention relates to a vehicle interior temperature lowering device that reduces the temperature of a passenger compartment that has been raised by direct sunlight by radiating heat into the atmosphere via a heat pipe.

炎天下に自動車を駐車しておくと車室内温度が上昇するが、この温度上昇の大きな要因の1つに、フロントウインドウ直下に配置されるインストルメントパネルに蓄熱した熱を車室内空気中に輻射することが考えられる。   When a car is parked under hot weather, the passenger compartment temperature rises, and one of the major causes of this temperature rise is radiation of the heat stored in the instrument panel placed directly under the front window into the passenger compartment air. It is possible.

このため、従来ではヒートパイプを用いてインストルメントパネルに蓄熱した熱を車室外に放熱することにより、車室内温度を降下するシステムが提案され、例えばヒートパイプの一端部をインストルメントパネルの裏面に取り付けるとともに、他端部をエンジンフード後端部に位置するカウル部分に外気に晒されるように配置したヒートシンクに取り付け、ヒートパイプの両端部間に温度勾配を発生させてインストルメントパネルに蓄熱した熱をヒートシンクから外気中に放熱するようにしたものが知られている(例えば、特許文献1参照)。
特開2004−84970号公報(第4頁、第1図)
For this reason, conventionally, a system has been proposed in which the heat stored in the instrument panel using a heat pipe is dissipated outside the passenger compartment to lower the passenger compartment temperature.For example, one end of the heat pipe is attached to the back of the instrument panel. At the same time, the other end is attached to a heat sink that is exposed to the outside of the cowl located at the rear end of the engine hood, and heat is stored in the instrument panel by generating a temperature gradient between both ends of the heat pipe. Is known to radiate heat from the heat sink into the outside air (see, for example, Patent Document 1).
JP 2004-84970 A (page 4, FIG. 1)

しかしながら、かかる従来の車室内温度降下システムでは、ヒートシンクをカウル部分に配置してあるため、外気に晒されるとはいえ直射日光を受ける部分であるため、ヒートパイプ両端部間の温度勾配を大きくすることができず、ひいては車室内温度を効率良く降下させることが困難となる。   However, in such a conventional vehicle interior temperature drop system, since the heat sink is arranged in the cowl portion, it is a portion that receives direct sunlight even though it is exposed to the outside air, so the temperature gradient between both ends of the heat pipe is increased. As a result, it is difficult to efficiently lower the passenger compartment temperature.

そこで、ヒートシンクを車体の最も低温部分である車体フロア下側に配置することにより、ヒートパイプ両端部間の温度勾配を大きくすることができるのであるが、この場合ヒートパイプを車室内のインストルメントパネル部分から一旦車室外に取り出して床下まで配索する必要があり、どうしても車体組み立ての便宜上、前記ヒートパイプを車室内部分と車室外部分とで2分割して、その2分割したヒートパイプを車体組み立て時に締結する手法が採られる。   Therefore, it is possible to increase the temperature gradient between both ends of the heat pipe by arranging the heat sink at the lower part of the vehicle body floor, which is the coldest part of the vehicle body. In this case, the heat pipe is connected to the instrument panel in the vehicle interior. It is necessary to take it out from the vehicle compartment and route it under the floor. For the convenience of vehicle body assembly, the heat pipe is divided into two parts, the vehicle interior part and the vehicle exterior part. A technique that is sometimes concluded is adopted.

この場合、室内側ヒートパイプと締結部との間、および締結部と室外側ヒートパイプとの間、でそれぞれ効率良く温度勾配を発生させる必要がある。   In this case, it is necessary to efficiently generate temperature gradients between the indoor heat pipe and the fastening portion and between the fastening portion and the outdoor heat pipe.

ところが、ヒートシンクをいかに低温部分に配置しても、締結部の雰囲気温度が高い場合には、室内側ヒートパイプの両端部間、つまり、室内側ヒートパイプを介して熱的に連結されるインストルメントパネルと締結部との間の温度勾配を大きく取ることができないため、結果的に車室内温度の降下率が低下してしまう。   However, no matter how the heat sink is arranged in the low temperature part, if the ambient temperature of the fastening portion is high, the instrument is thermally connected between both ends of the indoor heat pipe, that is, through the indoor heat pipe. Since the temperature gradient between the panel and the fastening portion cannot be made large, the rate of decrease in the passenger compartment temperature is consequently reduced.

そこで、本発明は室内側ヒートパイプと室外側ヒートパイプとの締結部を積極的に放熱させることにより、室内側ヒートパイプの両端部間の温度勾配を大きくして、車室内温度を効率良く降下させることができる車室内温度降下装置を提供するものである。   Therefore, the present invention actively dissipates the fastening portion between the indoor heat pipe and the outdoor heat pipe, thereby increasing the temperature gradient between both ends of the indoor heat pipe and efficiently lowering the vehicle interior temperature. A vehicle interior temperature lowering device that can be made to operate is provided.

本発明にあっては、車室内に設置した吸熱板に熱的に接続した室内側ヒートパイプと、車体フロア下側に設置した床下ヒートシンクに熱的に接続した室外側ヒートパイプと、車室外側でこれら室内側ヒートパイプと室外側ヒートパイプとを熱的に接続する締結部とを備え、該締結部に放熱手段を設けたことを最も主要な特徴とする。   In the present invention, an indoor heat pipe thermally connected to an endothermic plate installed in the vehicle interior, an outdoor heat pipe thermally connected to an underfloor heat sink installed below the vehicle body floor, and the vehicle exterior The most main feature is that a fastening portion for thermally connecting the indoor heat pipe and the outdoor heat pipe is provided, and a heat dissipating means is provided in the fastening portion.

本発明によれば、室内側ヒートパイプと室外側ヒートパイプとを熱的に接続した締結部を放熱手段により温度を下げることができるため、室内側ヒートパイプの両端部間、つまり車室内の吸熱板と締結部との間の温度勾配を大きくできる。   According to the present invention, since the temperature of the fastening portion that thermally connects the indoor heat pipe and the outdoor heat pipe can be lowered by the heat radiating means, the heat absorption between both ends of the indoor heat pipe, that is, the vehicle interior. The temperature gradient between the plate and the fastening portion can be increased.

一方、室外側ヒートパイプの両端部、つまり前記締結部と床下ヒートシンクとの間の温度勾配は、床下ヒートシンクが車体の低温部分に設置してあるため大きく保たれている。   On the other hand, the temperature gradient between both ends of the outdoor heat pipe, that is, the fastening portion and the underfloor heat sink is kept large because the underfloor heat sink is installed in the low temperature portion of the vehicle body.

従って、吸熱板と締結部との間および締結部と床下ヒートシンクとの間のそれぞれの温度勾配を大きくできるため、装置全体の温度降下を大きくして車室内温度を効率良く降下させることができる。   Accordingly, the temperature gradient between the heat absorbing plate and the fastening portion and between the fastening portion and the underfloor heat sink can be increased, so that the temperature drop of the entire apparatus can be increased and the passenger compartment temperature can be lowered efficiently.

以下、本発明の実施形態を図面と共に詳述する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 3 is an enlarged perspective view showing a coupling state of the fastening portion, and FIG. 4 is an exploded perspective view in which the fastening portion is enlarged.

本実施形態の車室内温度降下装置10は、図1に示すように自動車1の車室R内の前部に配置したインストルメントパネル2に設けられ、図2にも示すようにインストルメントパネル2の表皮下に設置した吸熱板11に熱的に接続した室内側ヒートパイプ12と、車体フロア3の下側に設置した床下ヒートシンクとしての床下放熱器13に熱的に接続した室外側ヒートパイプ14と、車室R外側でこれら室内側ヒートパイプ12と室外側ヒートパイプ14とを熱的に接続する締結部としての締結コネクタ15とを備え、該締結コネクタ15に放熱手段20を設けてある。   The vehicle interior temperature lowering device 10 according to the present embodiment is provided in an instrument panel 2 disposed at the front portion in the vehicle interior R of the automobile 1 as shown in FIG. 1, and as shown in FIG. The indoor side heat pipe 12 thermally connected to the heat sink 11 installed under the skin and the outdoor side heat pipe 14 thermally connected to the under-floor radiator 13 as the under-floor heat sink installed under the vehicle body floor 3. And a fastening connector 15 as a fastening portion for thermally connecting the indoor heat pipe 12 and the outdoor heat pipe 14 outside the vehicle compartment R, and a heat radiating means 20 is provided in the fastening connector 15.

本実施形態では前記吸熱板11は図2に示すようにインストルメントパネル2の車幅方向(図中左右方向)に分割して2箇所配置するとともに、室内側ヒートパイプ12を2本設け、各室内側ヒートパイプ12の一端部12aをそれぞれ対応する前記吸熱板11に熱的に接続する一方、各室内側ヒートパイプ12の他端部12bを、図1に示すようにフロントコンパートメントとしてのエンジンルームEと車室Rとを隔成するダッシュパネル4を貫通してエンジンルームE内に突出し、該他端部12bをエンジンルームE内に配置した締結コネクタ15に熱的に接続してある。   In the present embodiment, as shown in FIG. 2, the heat absorbing plate 11 is divided in the vehicle width direction (left and right direction in the figure) of the instrument panel 2 and arranged at two locations, and two indoor heat pipes 12 are provided, One end 12a of each indoor heat pipe 12 is thermally connected to the corresponding heat absorbing plate 11, while the other end 12b of each indoor heat pipe 12 is connected to the engine compartment as a front compartment as shown in FIG. The dash panel 4 that separates the E and the vehicle compartment R is penetrated to protrude into the engine room E, and the other end 12b is thermally connected to a fastening connector 15 disposed in the engine room E.

また、前記室外側ヒートパイプ14は2本設けてそれぞれをエンジンルームE内に配置し、それぞれの一端部14aを前記締結コネクタ15に熱的に接続して、図1に示すようにエンジンルームE内を下方に配索してダッシュパネル4の下側に廻り込ませ、その他端部14bを前記床下放熱器13に熱的に接続してある。   Further, two outdoor heat pipes 14 are provided and each is disposed in the engine room E, and one end portion 14a is thermally connected to the fastening connector 15, and as shown in FIG. The inside is routed downward and wraps around the lower side of the dash panel 4, and the other end 14 b is thermally connected to the underfloor radiator 13.

前記締結コネクタ15は、図3に示すようにアッパーコネクタ15Aとロアコネクタ15Bとで構成され、前記室内側ヒートパイプ12の他端部12bどうしをW字状に接続してアッパーコネクタ15A内に埋設するとともに、前記室外側ヒートパイプ14の一端部14aをロアコネクタ15Bの左右両側に結合してある。   As shown in FIG. 3, the fastening connector 15 is composed of an upper connector 15A and a lower connector 15B. The other end portions 12b of the indoor heat pipe 12 are connected in a W shape and embedded in the upper connector 15A. In addition, one end portion 14a of the outdoor heat pipe 14 is coupled to the left and right sides of the lower connector 15B.

前記アッパーコネクタ15Aと前記ロアコネクタ15Bは図4に示すように上下に分離可能となっており、それぞれの平坦な受熱面15Aa,15Baを図3に示すように密接させた状態で、アッパーコネクタ15Aに形成した取付孔15Abに挿通したボルト16をロアコネクタ15Bのねじ穴15Bbに螺合して締め付けてある。   The upper connector 15A and the lower connector 15B are separable up and down as shown in FIG. 4, and the upper connector 15A is brought into close contact with the flat heat receiving surfaces 15Aa and 15Ba as shown in FIG. The bolt 16 inserted into the mounting hole 15Ab formed in the above is screwed into the screw hole 15Bb of the lower connector 15B and tightened.

前記締結コネクタ15に設けた放熱手段20は、アッパーコネクタ15Aの上面に一体に突設した複数のひだ状の放熱フィン21によって形成してある。   The heat dissipating means 20 provided in the fastening connector 15 is formed by a plurality of pleated heat dissipating fins 21 integrally projecting on the upper surface of the upper connector 15A.

以上の構成により本実施形態の車室内温度降下装置10によれば、インストルメントパネル2に設置した吸熱板11は、室内側ヒートパイプ12および室外側ヒートパイプ14を介して車体フロア3の下側の低温部分に配置した床下放熱器13に熱的に接続されているため、直射日光により高温化したインストルメントパネル2の吸熱板11の温度と床下放熱器13との間に大きな温度差を発生させることができる。   With the above configuration, according to the vehicle interior temperature lowering device 10 of the present embodiment, the heat absorption plate 11 installed in the instrument panel 2 is located below the vehicle body floor 3 via the indoor heat pipe 12 and the outdoor heat pipe 14. Because it is thermally connected to the underfloor radiator 13 disposed in the low temperature part of the floor, a large temperature difference is generated between the temperature of the heat sink 11 of the instrument panel 2 and the underfloor radiator 13 that has been heated by direct sunlight. Can be made.

このとき、前記室内側ヒートパイプ12と前記室外側ヒートパイプ14とは締結コネクタ15を介して熱的に接続されるが、該締結コネクタ15には放熱手段20を設けてあるため、直射日光の温度が高くなる夏季にあって締結コネクタ15周りの雰囲気温度が高くなった場合にも、前記放熱手段20によって締結コネクタ15の温度を下げることができ、室内側ヒートパイプ12の両端部間、つまり車室R内の吸熱板11と締結コネクタ15との間の温度勾配を大きくできる。   At this time, the indoor heat pipe 12 and the outdoor heat pipe 14 are thermally connected via a fastening connector 15. Since the fastening connector 15 is provided with a heat radiation means 20, Even in the summer when the temperature rises and the ambient temperature around the fastening connector 15 becomes high, the temperature of the fastening connector 15 can be lowered by the heat dissipating means 20, and between the both ends of the indoor heat pipe 12, that is, The temperature gradient between the heat absorbing plate 11 and the fastening connector 15 in the passenger compartment R can be increased.

一方、室外側ヒートパイプ14の両端部間、つまり締結コネクタ15と床下放熱器13との間の温度勾配は、床下放熱器13が車体の低温部分に設置してあるため大きく保たれている。   On the other hand, the temperature gradient between both ends of the outdoor heat pipe 14, that is, between the fastening connector 15 and the underfloor radiator 13 is kept large because the underfloor radiator 13 is installed in the low temperature portion of the vehicle body.

従って、吸熱板11と締結コネクタ15との間および締結コネクタ15と床下放熱器13との間のそれぞれの温度勾配を大きくできるため、装置全体の温度降下を大きくして車室内温度を効率良く降下させることができる。   Accordingly, since the temperature gradient between the heat absorbing plate 11 and the fastening connector 15 and between the fastening connector 15 and the underfloor radiator 13 can be increased, the temperature drop of the entire apparatus is increased, and the temperature in the passenger compartment is efficiently lowered. Can be made.

このように締結コネクタ15に放熱手段20を設けた本実施形態の車室内温度降下装置10の車室内高温状態(吸熱板11が略90゜Cまで上昇)での温度降下代を、締結コネクタ15に放熱手段20を設けないものを従来として、それぞれを比較して以下示す。   In this way, the temperature reduction allowance of the vehicle interior temperature drop device 10 of the present embodiment in which the fastening connector 15 is provided with the heat dissipating means 20 in the vehicle interior high temperature state (the heat absorption plate 11 rises to approximately 90 ° C.) is expressed as the fastening connector 15. In the conventional example, the heat dissipating means 20 is not provided.

尚、以下、吸熱板11の温度をK、締結コネクタ15の温度をM、床下放熱器13の雰囲気温度をNとしてそれぞれ示すものとする。   Hereinafter, the temperature of the heat absorbing plate 11 is denoted by K, the temperature of the fastening connector 15 is denoted by M, and the ambient temperature of the underfloor radiator 13 is denoted by N.

<初期状態> K:90゜C、M:60゜C、N:40゜C
<作動安定時> K:70゜C、M:60゜C、N:40゜C
(2)本実施形態では、
<初期状態> K:90゜C、M:60゜C、N:40゜C
<作動安定時> K:60゜C、M:50゜C、N:40゜C
となり、放熱手段20を設けた本実施形態では、放熱手段20を設けない従来に比較して略10゜Cの温度降下を確認することができる。
(1) In the conventional example,
<Initial state> K: 90 ° C, M: 60 ° C, N: 40 ° C
<When operation is stable> K: 70 ° C, M: 60 ° C, N: 40 ° C
(2) In this embodiment,
<Initial state> K: 90 ° C, M: 60 ° C, N: 40 ° C
<When operation is stable> K: 60 ° C, M: 50 ° C, N: 40 ° C
Thus, in the present embodiment in which the heat dissipating means 20 is provided, a temperature drop of about 10 ° C. can be confirmed as compared with the conventional case in which the heat dissipating means 20 is not provided.

また、床下放熱器13の雰囲気温度が略50゜Cと高い場合の温度降下代を前記従来と比較して示す。   Further, the temperature drop allowance when the atmospheric temperature of the underfloor radiator 13 is as high as about 50 ° C. is shown in comparison with the conventional one.

(3)従来例では、
<初期状態> K:80゜C、 M:60゜C、 N:50゜C
<作動安定時> K:70゜C、 M:60゜C、 N:50゜C
(4)本実施形態では、
<初期状態> K:80゜C、 M:60゜C、 N:50゜C
<作動安定時> K:60゜C、 M:55゜C、 N:50゜C
となり、この場合にあっても放熱手段20を設けた本実施形態では、放熱手段20を設けない従来に比較して略10゜Cの温度降下を確認することができる。
(3) In the conventional example,
<Initial state> K: 80 ° C, M: 60 ° C, N: 50 ° C
<When operation is stable> K: 70 ° C, M: 60 ° C, N: 50 ° C
(4) In this embodiment,
<Initial state> K: 80 ° C, M: 60 ° C, N: 50 ° C
<When operation is stable> K: 60 ° C, M: 55 ° C, N: 50 ° C
Even in this case, in the present embodiment in which the heat dissipating means 20 is provided, a temperature drop of about 10 ° C. can be confirmed as compared with the conventional case in which the heat dissipating means 20 is not provided.

また、前記(4)に示す本実施形態の場合は、締結コネクタ15の安定状態での温度Mは55゜Cとなるが、過渡状態では放熱手段20の機能により一時的に50゜C近傍まで下がることが確認されており、吸熱板11の温度Kを期待通りに60゜Cまで低下させることができる。   In the case of this embodiment shown in (4) above, the temperature M in the stable state of the fastening connector 15 is 55 ° C., but in the transient state, it is temporarily close to 50 ° C. by the function of the heat dissipating means 20. It has been confirmed that the temperature K of the endothermic plate 11 can be lowered to 60 ° C. as expected.

また、本実施形態では前記放熱手段20を、アッパーコネクタ15の上面に形成した放熱フィン21で形成したので、安価な構成にして効率良く放熱することができる。   Further, in the present embodiment, since the heat radiating means 20 is formed by the heat radiating fins 21 formed on the upper surface of the upper connector 15, it is possible to efficiently radiate heat with an inexpensive configuration.

更に、前記締結コネクタ15はエンジンルームE内に配置してあって、該エンジンルームE内は吸熱板11を配設した車室R内よりも温度が低く、かつ、床下放熱器13を配設した車体フロア3下部よりも温度が高いため、吸熱板11と締結コネクタ15との間および締結コネクタ15と床下放熱器13との間にそれぞれ温度勾配を確保し易くなる。   Further, the fastening connector 15 is disposed in the engine room E. The temperature in the engine room E is lower than that in the passenger compartment R in which the heat absorbing plate 11 is disposed, and the underfloor radiator 13 is disposed. Since the temperature is higher than the lower part of the vehicle body floor 3, it is easy to secure a temperature gradient between the heat absorbing plate 11 and the fastening connector 15 and between the fastening connector 15 and the underfloor radiator 13.
