Description

本発明は、電気電子機器収納用ボックス等に取り付けて盤内温度を制御するペルチェ式盤用冷却装置に関するものである。   The present invention relates to a cooling device for a Peltier type board that is attached to an electric / electronic equipment storage box or the like and controls the temperature inside the board.

電気電子機器収納用ボックス等のための盤用冷却装置として、ペルチェ素子を利用した電子式クーラーが知られている。この電子式クーラーは外気を盤内に導入することなく盤内冷却が可能であるので、特に外部からのダストの侵入を嫌う電子機器収納用ボックスに適している。電子式クーラーは内部機器の発熱量が小さい場合には、温度・湿度制御装置によってペルチェ素子への通電量を減少させたり、オンオフ運転を行わせたりして省エネルギー運転が可能である。   2. Description of the Related Art An electronic cooler using a Peltier element is known as a panel cooling device for an electric / electronic equipment storage box or the like. Since this electronic cooler can cool the inside of the board without introducing outside air into the board, it is particularly suitable for an electronic equipment storage box that does not like the entry of dust from the outside. When the amount of heat generated by the internal device is small, the electronic cooler can be operated in an energy-saving manner by reducing the amount of current supplied to the Peltier element by the temperature / humidity control device or by performing an on / off operation.

また本出願人の特許文献１に示すように、ペルチェ素子の両側に、盤内用ファンを備えた盤内流体循環経路と盤外用ファンを備えた盤外流体循環経路とをそれぞれ形成するとともに、これらの経路を盤内用ファンと盤外用ファンとの間の直接循環経路へ切替えることができるようにした盤用冷却装置も用いられている。この特許文献１の装置は、ペルチェ素子を用いた通常の冷却運転のほかに、ペルチェ素子への通電を停止したまま盤内用ファンと盤外用ファンとの間で流体を循環させる熱交換運転を行うことも可能であり、更に省エネルギー効果を高めたものである。   Further, as shown in Patent Document 1 of the present applicant, on both sides of the Peltier element, an in-board fluid circulation path having an in-panel fan and an out-board fluid circulation path having an out-board fan are formed, respectively. There is also used a panel cooling device which can switch these paths to a direct circulation path between the panel fan and the panel external fan. In addition to the normal cooling operation using the Peltier element, the device of Patent Document 1 performs a heat exchange operation in which fluid is circulated between the internal fan and the external fan while energizing the Peltier element is stopped. It is also possible to carry out, and further enhance the energy saving effect.

上記のように、従来から盤用冷却装置については様々な改良が行われている。しかし、その多くは盤内温度を適正範囲に制御することを目的としたものであり、盤内湿度を考慮したものはあまり見受けられない。また別に除湿装置を設置することも考えられるが、設備が複雑化して設備コストが高くなり、また高温多湿の場合には電子式クーラーと除湿装置を同時に運転することとなるため、使用電力量が多くなりランニングコストも高くなるという問題がある。
特開２００６−３２７５４号公報 As described above, various improvements have been made on the panel cooling device. However, many of them are intended to control the temperature in the panel within an appropriate range, and there are not many that take into account the humidity in the panel. It is possible to install a dehumidifier separately, but the equipment becomes complicated and the equipment cost becomes high, and in the case of high temperature and high humidity, the electronic cooler and the dehumidifier are operated at the same time. There is a problem that the running cost increases as the number increases.
JP 2006-32754 A

本発明は上記した従来の問題点を解決し、同一の装置を効率的に用いて、クーラー運転と熱交換運転と除湿運転とを行うことができる、省エネルギー効果に優れたペルチェ式盤用冷却装置を提供することを目的とするものである。   The present invention solves the above-described conventional problems, and can efficiently perform a cooler operation, a heat exchange operation, and a dehumidifying operation using the same device, and is excellent in energy saving effect. Is intended to provide.

上記の課題を解決するためになされた本発明は、盤内冷却用のペルチェ素子の両側に、盤内用ファンと盤外用ファンを設けるとともに、温度センサ及び湿度センサが接続される温度・湿度制御装置を設け、この温度・湿度制御装置に、盤内温度が第１所定温度を超えた時にはペルチェ素子に定格電流を流してクーラー運転とし、盤内温度が第２所定温度を下回る時にはペルチェ素子に微弱電流を流すか若しくは通電を停止して熱交換運転とし、盤内温度が第１所定温度を超えなくても盤内湿度が所定湿度を超えた時にはペルチェ素子に定格電流を流して除湿運転として動作させる機能を持たせたことを特徴とするものである。なお、温度・湿度制御装置に、盤内温度が第１所定温度を超えなくても盤内湿度が所定湿度を超えた時にはペルチェ素子に定格電流を流して除湿運転として動作させ、盤内温度が所定温度以下の時には盤内用ファンを停止させる機能を持たせることが好ましく、さらに、温度が設定値以下となったときにペルチェ素子への通電電流を反転させてヒータとして作用させる機能を持たせることもできる。   In order to solve the above-mentioned problems, the present invention provides a temperature / humidity control in which a panel internal fan and a panel external fan are provided on both sides of a Peltier element for cooling in the panel, and a temperature sensor and a humidity sensor are connected. The temperature / humidity control device is provided with a rated current flowing through the Peltier element when the temperature inside the panel exceeds the first predetermined temperature to cooler operation, and when the temperature inside the panel falls below the second predetermined temperature, When a weak current is applied or power is turned off and the heat exchange operation is performed, even if the internal temperature does not exceed the first predetermined temperature, if the internal humidity exceeds the predetermined humidity, the rated current is supplied to the Peltier element to perform the dehumidification operation. It is characterized by having a function to operate. Even if the temperature inside the panel does not exceed the first predetermined temperature, the temperature / humidity control device allows the rated current to flow through the Peltier element to operate as a dehumidifying operation when the panel humidity exceeds the predetermined humidity. It is preferable to have a function of stopping the internal fan when the temperature is lower than a predetermined temperature. Further, when the temperature is lower than the set value, a function is provided to reverse the energization current to the Peltier element to act as a heater. You can also.

本発明のペルチェ式盤用冷却装置によれば、盤内温度が第１所定温度を超えた時にはペルチェ素子に定格電流を流してクーラー運転とし、盤内温度が第２所定温度を下回る時にはペルチェ素子に微弱電流を流すか若しくは通電を停止して熱交換運転とし、盤内温度が第１所定温度を超えなくても盤内湿度が所定湿度を超えた時にはペルチェ素子に定格電流を流して除湿運転として動作させるようにしたものであり、同一の装置によって、クーラー運転と熱交換運転と除湿運転とを行わせることができる。   According to the cooling device for a Peltier type panel of the present invention, when the temperature in the panel exceeds the first predetermined temperature, a rated current is passed through the Peltier element to perform the cooler operation, and when the temperature in the panel is lower than the second predetermined temperature, the Peltier element. A weak current is passed through or the power is turned off and the heat exchange operation is performed. Even if the panel internal temperature does not exceed the first predetermined temperature, if the panel internal humidity exceeds the predetermined humidity, the rated current is supplied to the Peltier element to perform the dehumidification operation. The cooler operation, the heat exchange operation, and the dehumidification operation can be performed by the same device.

以下に本発明の好ましい実施形態を示す。
図１は本発明の実施形態の説明図であり、１は電気電子機器収納用ボックス、２は盤内と盤外とを区画する隔壁である。３はこの隔壁２の部分に配置されたペルチェ素子であって、温度・湿度制御装置４によって運転制御が行われている。 Preferred embodiments of the present invention are shown below.
FIG. 1 is an explanatory view of an embodiment of the present invention. Reference numeral 1 denotes an electric / electronic equipment storage box, and 2 denotes a partition partitioning the inside of the board and the outside of the board. Reference numeral 3 denotes a Peltier element disposed in the partition wall 2, and the operation is controlled by the temperature / humidity control device 4.

ペルチェ素子３の盤内側と盤外側にはそれぞれ、盤内側ヒートシンク５と盤外側ヒートシンク６とが設けられている。また各ヒートシンク５，６にはそれぞれ、盤内用ファン７、盤外用ファン９が設けられている。通常はペルチェ素子３に電流を流し、盤内のクーラー運転が行われる。   A board-side heat sink 5 and a board-side heat sink 6 are provided on the inner side and the outer side of the Peltier element 3, respectively. Each of the heat sinks 5 and 6 is provided with an internal fan 7 and an external fan 9. Usually, a current is passed through the Peltier element 3 to perform a cooler operation in the panel.

また、ペルチェ素子３に電流を流さず、盤内用ファン７と盤外用ファン９とを動作させることによりペルチェ素子３を使用しない熱交換運転を行うことができる。この際にペルチェ素子３の定格の１０％程度に相当する微弱電流を流す熱交換運転を行えば、熱交換効率を高めることができる。   Further, the heat exchange operation without using the Peltier device 3 can be performed by operating the in-panel fan 7 and the out-of-panel fan 9 without passing a current through the Peltier element 3. At this time, heat exchange efficiency can be improved by performing a heat exchange operation in which a weak current corresponding to about 10% of the rating of the Peltier element 3 is applied.

温度・湿度制御装置４には温度センサ１６及び湿度センサ１７が接続されており、温度センサ１６により検出された盤内温度が第１所定温度、例えば３５℃を越えたときにはペルチェ素子３に正方向に直流を通電し、通常のクーラー運転を行う。その結果、盤内温度が第２所定温度、例えば３０℃を下回るまで低下するとペルチェ素子３への通電を停止するか、定格の１０％程度である微弱電流まで通電量を減少させ、熱交換運転に切替える。何れの場合にも、盤内用ファン７と盤外用ファン９とはともに回転される。そして盤内温度が第３所定温度、例えば２５℃にまで低下すると熱交換運転も停止する。このようにして、クーラー運転と熱交換運転とを切替えることにより、省エネルギー効果を発揮させることができる。   A temperature sensor 16 and a humidity sensor 17 are connected to the temperature / humidity control device 4, and when the temperature inside the panel detected by the temperature sensor 16 exceeds a first predetermined temperature, for example, 35 ° C., the Peltier element 3 has a positive direction. Apply a direct current to the and perform normal cooler operation. As a result, when the temperature in the panel drops to a second predetermined temperature, for example, below 30 ° C., the energization to the Peltier element 3 is stopped, or the energization amount is reduced to a weak current that is about 10% of the rating, and heat exchange operation Switch to. In any case, both the in-board fan 7 and the out-board fan 9 are rotated. And if the temperature in a board falls to the 3rd predetermined temperature, for example, 25 degreeC, a heat exchange operation will also be stopped. Thus, the energy saving effect can be exhibited by switching between the cooler operation and the heat exchange operation.

上記のような運転方法は従来と同様であるが、本発明では湿度センサ１７により検出された盤内湿度が温度・湿度制御装置４に入力されており、温度・湿度制御装置４は検出された盤内湿度が所定湿度を越えたときに、ペルチェ素子３に除湿運転を行わせる機能を有する。以下にこの点について詳述する。   The operation method as described above is the same as the conventional method, but in the present invention, the humidity inside the panel detected by the humidity sensor 17 is input to the temperature / humidity control device 4, and the temperature / humidity control device 4 is detected. It has a function of causing the Peltier element 3 to perform a dehumidifying operation when the humidity inside the panel exceeds a predetermined humidity. This point will be described in detail below.

除湿運転は、盤内湿度が所定湿度、例えば７０％以上に達したときに行われ、７０％未満にまで低下すると停止される。除湿運転は、ペルチェ素子３に正方向に直流が通電される。しかし盤内温度に応じて除湿運転の方法が異なり、高温域、例えば盤内温度が３０℃以上での除湿運転の場合にはクーラー運転と同様に盤内用ファン７と盤外用ファン９とをともに回転させるが、中温域（例えば１５〜２５℃）及び中高温域（例えば２５〜３０℃）の所定温度以下では盤内用ファン７を停止し、盤外用ファン９のみを回転させる。   The dehumidifying operation is performed when the humidity in the panel reaches a predetermined humidity, for example, 70% or more, and is stopped when the humidity decreases to less than 70%. In the dehumidifying operation, a direct current is applied to the Peltier element 3 in the positive direction. However, the method of the dehumidifying operation differs depending on the temperature in the panel, and in the case of the dehumidifying operation at a high temperature range, for example, the temperature in the panel is 30 ° C. or higher, the fan 7 for the panel and the fan 9 for the panel are connected as in the cooler operation. Both of them are rotated, but the in-board fan 7 is stopped and only the out-board fan 9 is rotated at or below a predetermined temperature in an intermediate temperature region (for example, 15 to 25 ° C.) and an intermediate high temperature region (for example, 25 to 30 ° C.).

図２に、本発明の盤用冷却装置の作動と、盤内温度、盤内湿度との関係を示す。なおここに示された温度や湿度の絶対値は一例を示すに過ぎず、適宜変更可能であることはいうまでもない。   FIG. 2 shows the relationship between the operation of the panel cooling device of the present invention, the panel temperature, and the panel humidity. It should be noted that the absolute values of temperature and humidity shown here are merely examples and can be changed as appropriate.

まず盤内温度が第１所定温度である３５℃（Ａ点）に達すると、湿度の高低とは無関係にクーラー運転が行われる。クーラー運転は十分な冷却能力を発揮するように設計されているため、盤内温度は次第に低下し、第２所定温度３０℃（Ｂ点）に達するとクーラー運転は停止され、熱交換運転に切り替る。熱交換運転の冷却能力はクーラー運転に比べて低いが、盤用冷却装置全体を停止した場合に比較すれば大きい冷却能力を持つので、図２に示すように盤内温度はＨ点に向かって再び上昇し始める。   First, when the temperature in the panel reaches 35 ° C. (point A), which is the first predetermined temperature, the cooler operation is performed regardless of the humidity level. Since the cooler operation is designed to exhibit sufficient cooling capacity, the temperature in the panel gradually decreases, and when the second predetermined temperature of 30 ° C (point B) is reached, the cooler operation is stopped and switched to the heat exchange operation. The Although the cooling capacity of the heat exchange operation is lower than that of the cooler operation, it has a large cooling capacity as compared with the case where the entire panel cooling device is stopped. Therefore, as shown in FIG. It begins to rise again.

盤内湿度が７０％未満であれば、実線で示すように盤内温度に応じて上記の運転パターンが繰り返されるが、仮にＣ点において盤内湿度が所定湿度７０％以上となると、熱交換運転から除湿運転への切替えが行われる。このような高温域における除湿運転はクーラー運転と同じであり、その結果、盤内温度は破線で示すようにＤ点まで低下するとともに、盤内湿度も７０％未満にまで低下する。すると除湿運転の必要がなくなるため、再び熱交換運転に切り替り、Ｅ点で盤内湿度が７０％以上となると、再び熱交換運転から除湿運転への切替えが行われる。このようにして除湿運転と熱交換運転とが繰り返されて盤内の除湿が行われる。   If the humidity in the panel is less than 70%, the above operation pattern is repeated according to the temperature in the panel as shown by the solid line. However, if the humidity in the panel reaches a predetermined humidity of 70% or more at point C, the heat exchange operation is performed. Is switched to the dehumidifying operation. The dehumidifying operation in such a high temperature region is the same as the cooler operation. As a result, the temperature in the panel decreases to point D as indicated by the broken line, and the humidity in the panel also decreases to less than 70%. Then, since the necessity for the dehumidifying operation is eliminated, the operation is switched again to the heat exchanging operation, and when the humidity in the panel becomes 70% or more at the point E, the switching from the heat exchanging operation to the dehumidifying operation is performed again. In this way, the dehumidification operation and the heat exchange operation are repeated to dehumidify the inside of the panel.

図２の例では、Ｆ点において盤内温度が３０℃となり、かつ盤内湿度も７０％未満にまで低下したので、実線の場合にも破線の場合にも除湿運転、クーラー運転ともに停止され、熱交換運転が継続される。外気温が低くなると熱交換運転によって盤内温度が低下し、Ｇ点で２５℃に達すると熱交換運転も停止する。しかしＩ‐Ｊのように盤内湿度が上昇し始め、Ｊ点において７０％に達するとまた除湿運転が開始されることは、上記した場合と同様である。   In the example of FIG. 2, at the point F, the temperature inside the panel is 30 ° C. and the humidity inside the panel is reduced to less than 70%, so both the dehumidifying operation and the cooler operation are stopped both in the case of the solid line and the broken line, The heat exchange operation is continued. When the outside air temperature decreases, the temperature in the panel decreases due to the heat exchange operation, and when the temperature reaches 25 ° C. at the point G, the heat exchange operation also stops. However, as in the case of IJ, the humidity inside the panel starts to rise and the dehumidifying operation is started again when it reaches 70% at the point J.

このように、盤内温度が２５℃以上の中高温域及び３０℃以上の高温域では、クーラー運転、熱交換運転のいずれかが行われ、盤内湿度に応じて除湿運転が断続的に繰り返される。そして盤内温度が２５℃未満の適正温度域となると、クーラー運転、熱交換運転の何れも停止される。しかし盤内湿度が７０％に達することはあるため、盤内温度が２５℃未満の適正温度域においても、上記と同様に除湿運転は行われる。ただしこの除湿運転中は、盤内用ファン７は停止し、盤外用ファン９のみを回転させる。   As described above, either the cooler operation or the heat exchange operation is performed in the medium high temperature range of 25 ° C. or higher and the high temperature range of 30 ° C. or higher, and the dehumidification operation is repeated intermittently according to the humidity in the panel. It is. Then, when the temperature in the panel reaches an appropriate temperature range of less than 25 ° C., both the cooler operation and the heat exchange operation are stopped. However, since the humidity in the panel may reach 70%, the dehumidifying operation is performed in the same manner as described above even in an appropriate temperature range where the temperature in the panel is less than 25 ° C. However, during this dehumidifying operation, the internal fan 7 is stopped and only the external fan 9 is rotated.

なお、盤内温度が１５〜２５℃の適正温度域にあるときは、盤内を冷却する必要はないが、外気温の低下に伴って５℃未満の低温域にまで低下したときには、ペルチェ素子への通電電流を反転させてヒータとして作用させる。   When the temperature inside the panel is in an appropriate temperature range of 15 to 25 ° C., it is not necessary to cool the inside of the panel. However, when the outside temperature falls to a low temperature range below 5 ° C., the Peltier element The energizing current is reversed to act as a heater.

上記したように本発明のペルチェ式盤用冷却装置によれば、同一の装置を効率的に用いて、クーラー運転と熱交換運転と除湿運転とを行うことができる。   As described above, according to the Peltier-type board cooling device of the present invention, it is possible to perform the cooler operation, the heat exchange operation, and the dehumidification operation by efficiently using the same device.
