例えば、無線通信基地局のような電子機器は、その本体が屋外に設置されるので、本体内部の通信設備の発熱や、外気（特に太陽からの輻射熱）によって、本体内が温度上昇する。
For example, since an electronic device such as a wireless communication base station is installed outdoors, the temperature inside the device rises due to heat generated by communication equipment inside the device and outside air (especially radiant heat from the sun).
この本体内の温度上昇が所定値を超えると、本体内部の通信設備の稼動に異常をきたすことがあるので、本体のドア用開口部に、熱交換装置を配置し、室外空気で、本体内の室内空気を冷却している。
If the temperature rise in the main unit exceeds a predetermined value, the operation of the communication equipment inside the main unit may be abnormal. Therefore, a heat exchange device is installed in the door opening of the main unit, and the outdoor air The room air is cooled.

When the temperature measured by the temperature sensor 24 becomes higher than the first set temperature set at 25 ° C., the outdoor air suction fan 15 is activated. Thereafter, as the temperature rises, the rotational speed of the outdoor air suction fan 15 is gradually increased.
つまり、温度センサ２４によって測定した温度が例えば２５℃に設定した第１の設定温度よりも高くなると、室内空気吸込ファン２０と、室外空気吸込ファン１５を駆動させる。そして、電子機器本体２内の空気である室内空気を、熱交換器１７で室外空気と熱交換させて冷却し、それによって得られた低温の空気を、室内空気吹出口１４から電子機器本体２内に向けて吹き出し、電子機器本体２内の通信設備を冷却する。
That is, when the temperature measured by the temperature sensor 24 becomes higher than the first set temperature set to 25 ° C., for example, the indoor air suction fan 20 and the outdoor air suction fan 15 are driven. And the indoor air which is the air in the electronic device main body 2 is cooled by exchanging heat with the outdoor air in the heat exchanger 17, and the low-temperature air obtained thereby is discharged from the indoor air outlet 14 to the electronic device main body 2. The communication equipment in the electronic device main body 2 is cooled by blowing inward.
そして、このような冷却を行っているにも関わらず、例えば電子機器本体２の外気温度が異常に上昇したとする。そして、温度センサ２４によって測定した温度が例えば４５度に設定した第２の設定温度よりも高くなると、ペルチェ素子１８の冷房運転を行う（ステップＳ６、ステップＳ７）。
Suppose, for example, that the outside air temperature of the electronic device body 2 has risen abnormally despite such cooling. When the temperature measured by the temperature sensor 24 becomes higher than the second set temperature set at 45 degrees, for example, the Peltier element 18 is cooled (steps S6 and S7).
すなわち、ペルチェ素子１８の第２の放熱フィン２３を低温、ペルチェ素子１８の第１の放熱フィン１９を高温とする。
That is, the second radiating fin 23 of the Peltier element 18 is set to a low temperature, and the first radiating fin 19 of the Peltier element 18 is set to a high temperature.
その結果、熱交換器１７で室外空気と熱交換され、所定量は温度低下した電子機器本体２内の空気である室内空気を、低温化した第２の放熱フィン２３を通過させることによりさらに温度低下させ、室内空気吹出口１４から電子機器本体２内に向けて吹き出し、電子機器本体２内の通信設備を冷却する。
As a result, heat is exchanged with the outdoor air in the heat exchanger 17, and a predetermined amount of the indoor air, which is the air in the electronic device main body 2 whose temperature has been lowered, is passed through the second radiating fins 23 which has been lowered in temperature. Then, the air is blown out from the indoor air outlet 14 into the electronic device main body 2 to cool the communication equipment in the electronic device main body 2.
また、このようなペルチェ素子１８の冷房運転を実行すると、ペルチェ素子１８の第１の放熱フィン１９は高温化する。そこで、室外空気吸込ファン１５によって室外空気吸込口１０から本体ケース９内に吸い込まれた室外空気の一部を、高温化したペルチェ素子１８の第１の放熱フィン１９の外周を通過させる。その後、第１の放熱フィン１９で暖められた室外空気を排気口１１から室外に向かって排出することで、第１の放熱フィン１９の放熱を行う。
Further, when such a cooling operation of the Peltier element 18 is executed, the first radiating fins 19 of the Peltier element 18 are heated. Therefore, a part of the outdoor air sucked into the main body case 9 from the outdoor air suction port 10 by the outdoor air suction fan 15 is passed through the outer periphery of the first radiating fin 19 of the Peltier element 18 that has been heated. Thereafter, the outdoor air warmed by the first radiating fins 19 is discharged from the exhaust port 11 toward the outdoor side, whereby the first radiating fins 19 are radiated.
ここで、ペルチェ素子１８の第１の放熱フィン１９は高温で放熱側であり、通過させる室外空気は低温の方がよいため、第１の放熱フィン１９の外周を通過させる室外空気は熱交換器１７を通過させず、熱交換器１７側とは分流した室外空気を通過させている。
Here, the first radiating fin 19 of the Peltier element 18 is on the heat radiating side at a high temperature, and the outdoor air to be passed should have a low temperature. Therefore, the outdoor air passing through the outer periphery of the first radiating fin 19 is a heat exchanger. 17 is not allowed to pass through, but outdoor air that has been diverted from the heat exchanger 17 side is allowed to pass.
その結果、ペルチェ素子１８の冷房運転は効果的に行われ、徐々に電子機器本体２内の室内空気は温度低下することとなり、以降は、温度センサ２４によって測定した温度によって、室外空気吸込ファン１５と室内空気吸込ファン２０の回転数を制御する（ステップＳ８）。
As a result, the cooling operation of the Peltier element 18 is effectively performed, and the temperature of the indoor air in the electronic device main body 2 gradually decreases. Thereafter, the outdoor air suction fan 15 depends on the temperature measured by the temperature sensor 24. And the rotation speed of the indoor air suction fan 20 is controlled (step S8).
また、温度センサ２４によって測定した温度が低温駆動温度、例えば５℃に設定した低温駆動温度（低温駆動温度＜第１の設定温度＜第２の設定温度）以下になると、ペルチェ素子１８の暖房運転を行う（ステップＳ９、ステップＳ１０）。
When the temperature measured by the temperature sensor 24 is equal to or lower than a low temperature driving temperature, for example, a low temperature driving temperature set to 5 ° C. (low temperature driving temperature <first set temperature <second set temperature), the Peltier element 18 is heated. (Step S9, Step S10).
すなわち、ペルチェ素子１８の第２の放熱フィン２３を高温、ペルチェ素子１８の第１の放熱フィン１９を低温とする。
That is, the second radiating fin 23 of the Peltier element 18 is set to a high temperature, and the first radiating fin 19 of the Peltier element 18 is set to a low temperature.
このときには、図１２および図１３に示すように、室外空気吸込ファン１５は駆動されていないが、室内空気吸込ファン２０は低速駆動されているので、室内空気をペルチェ素子１８の第２の放熱フィン２３で温度上昇させる。第２の放熱フィン２３で温度上昇した室内空気を、室内空気吹出口１４から電子機器本体２に向かって吹き出すことで、電子機器本体２内の通信設備を暖気状態とする。
At this time, as shown in FIGS. 12 and 13, the outdoor air suction fan 15 is not driven, but the indoor air suction fan 20 is driven at a low speed. 23, the temperature is raised. By blowing out the room air whose temperature has been raised by the second radiating fins 23 from the indoor air outlet 14 toward the electronic device main body 2, the communication equipment in the electronic device main body 2 is brought into a warm-air state.
なお、上記実施の形態では、ドア６に設けた開口部７に、熱交換装置８を設置したが、ドア６を廃止し、熱交換装置８自体で、ドア６を設置していたドア設置用開口部を覆うようにしても良い。
In the above embodiment, the heat exchange device 8 is installed in the opening 7 provided in the door 6, but the door 6 is abolished and the door 6 is installed in the heat exchange device 8 itself. The opening may be covered.
以上のように本発明における電子機器は、設置環境に関わらず、冷却対象の冷却が十分に行えるので、通信基地局などの各種電子機器の冷却装置として活用することができる。
As described above, since the electronic device according to the present invention can sufficiently cool the cooling target regardless of the installation environment, it can be used as a cooling device for various electronic devices such as a communication base station.
