すなわち、第１環境用の第１吸気口１１、第１環境用の第１吐出口１２、第２環境用の第２吸気口１３、第２環境用の第２吐出口１４を有する本体ケース５ａと、この本体ケース５ａ内に設けられた熱交換器１７と、この熱交換器１７により前記第１吸気口１１から吸い込んだ第１環境の空気と、前記第２吸気口１３から吸い込んだ第２環境の空気とを熱交換させる第１送風機１５、第２送風機１６とを備えている。前記熱交換器１７は、第１〜第３のひし形板体１８〜２０を所定間隔離して積層したひし形柱状形状とし、この熱交換器１７の第１コーナ２１に隣接する一方の辺を第１環境用の第１流入口２２、他方の辺を第２環境用の第２流入口２３とし、この第１コーナ２１に対向する第２コーナ２４に隣接する辺で、前記第２流入口２３側の辺を第１環境用の第１流出口２５とし、前記第１流入口２２側の辺を第２環境用の第２流出口２６とし、前記第２コーナ２４を挟んで第１流出口２５側に前記第１送風機１５を配置し、前記第２コーナ２４を挟んで第２流出口２６側に前記第２送風機１６を配置することで、一定の大きさの本体ケース５ａ内に第１環境用の風路と第２環境用の風路を容易に形成することができる。すなわち、冷却ユニット５の本体ケース５ａ内に、下方のキャビネット３内を略垂直方向に循環させる風路と、外気を略水平方向に通過させる風路の構成を容易に形成して通気抵抗の差を少なくして熱交換効率を向上させることができる。 That is, the main body case 5a having the first intake port 11 for the first environment, the first discharge port 12 for the first environment, the second intake port 13 for the second environment, and the second discharge port 14 for the second environment. The heat exchanger 17 provided in the main body case 5a, the air in the first environment sucked from the first air inlet 11 by the heat exchanger 17, and the second air sucked from the second air inlet 13. A first blower 15 and a second blower 16 that exchange heat with environmental air are provided. The heat exchanger 17 has a rhombus columnar shape in which the first to third rhombus plates 18 to 20 are laminated with a predetermined interval therebetween, and one side adjacent to the first corner 21 of the heat exchanger 17 is a first side.

The first blower 15 is arranged on the side, and the second blower 16 is arranged on the second outlet 26 side with the second corner 24 in between, so that the first environment is placed in the body case 5a having a certain size. The air path for the second environment and the air path for the second environment can be easily formed. That is, a difference in ventilation resistance is easily formed in the body case 5a of the cooling unit 5 by easily forming a configuration of an air passage that circulates in the lower cabinet 3 in a substantially vertical direction and an air passage that allows outside air to pass in a substantially horizontal direction. And the heat exchange efficiency can be improved.

特に、第１コーナ２１、第２コーナ２４は、ひし形の鋭角とし、第２コーナ２４は、第１送風機１５、第２送風機１６間に突入させたものであるから、第１送風機１５と第２送風機１６は、送風機本体部分を、それぞれ、第４コーナ２８と第３コーナ２７側に向けて張り出して配置することができ、ファンの直径を大きくとることができる。 In particular, the first corner 21 and the second corner 24 have rhombus acute angles, and the second corner 24 is inserted between the first blower 15 and the second blower 16. The blower 16 can be arranged so that the blower main body portion protrudes toward the fourth corner 28 and the third corner 27 side, and the diameter of the fan can be increased.

また、第１流出口２５から第１送風機吸込口３１へ連通する第１風路３３と第２流出口２６から第２送風機吸込口３２へ連通する第２風路３４が熱交換器１７と仕切り板３０によって、仕切り板３０を第２コーナ２４から本体ケース５ａの側面へ向けて延設するだけで容易に形成することができる。 The first air passage 33 that communicates from the first outlet 25 to the first blower inlet 31 and the second air passage 34 that communicates from the second outlet 26 to the second blower inlet 32 partition the heat exchanger 17. The partition plate 30 can be easily formed by the plate 30 only by extending from the second corner 24 toward the side surface of the main body case 5a.

また、本体ケース５ａ内の第１、第２送風機１５、１６間に仕切り板３０を設けることで、第１流出口２５から第１送風機吸込口３１へ第１風路３３が形成され第１流出口２５から流出した外気は、この仕切り板３０の一方の面に沿って案内され流れることとなる。そして、仕切り板３０に対向した第１送風機吸込口３１から吸い込まれることとなる。また、同様に、第２送風機吸込口３２側にも第２風路３４が形成され、第２流出口２６から流出したキャビネット３内の空気は仕切り板３０の他方の面に沿って案内され流れることとなる。そして、この仕切り板３０に対向した第２送風機吸込口３２から吸い込まれることとなる。 Further, by providing the partition plate 30 between the first and second blowers 15 and 16 in the main body case 5a, the first air flow path 33 is formed from the first outlet 25 to the first blower inlet 31 and the first flow. The outside air flowing out from the outlet 25 is guided and flows along one surface of the partition plate 30. And it will be inhaled from the 1st air blower inlet 31 which opposed the partition plate 30. FIG. Similarly, a second air passage 34 is also formed on the second blower inlet 32 side, and the air in the cabinet 3 flowing out from the second outlet 26 is guided and flows along the other surface of the partition plate 30. It will be. And it will be inhaled from the 2nd air blower inlet 32 which opposed this partition plate 30. FIG.

また、熱交換器１７は、３枚以上のひし形板体１８を所定間隔離して本体ケース５ａの底面から上面方向へ積層したひし形柱状形状としたことで、本体ケース５ａ内の第１流入口２２と第２流入口２３は、第１空間２１ａと第２空間２１ｂへ開口する構成ができ、第１吸気口１１および第２吸気口１３から流入した空気は、これら第１空間２１ａおよび第２空間２１ｂでそれぞれ層流をなして熱交換器１７へ流入することができ大きな風量を得るこができる。 Further, the heat exchanger 17 has a rhombus columnar shape in which three or more rhombus plates 18 are separated from each other by a predetermined distance and stacked from the bottom surface to the top surface of the main body case 5a, so that the first inflow port 22 in the main body case 5a. The second inflow port 23 can be configured to open to the first space 21a and the second space 21b, and the air flowing in from the first air inlet 11 and the second air inlet 13 flows into the first space 21a and the second space 21. In 21b, each can flow into the heat exchanger 17 in a laminar flow, and a large air volume can be obtained.

また、本体ケース５ａは、正面および背面の内部に内側板５ｂを等脚台形形状に形成し、その内側板５ｂを下広がりに傾斜させて形成したことで、その上部に開口した第１吐出口１２と第１吸気口１１はそれぞれ下方に配置した吐出ガラリ７と吸込ガラリ６へ側面の傾斜を伝わって空気を流すことができキャビネット３内の一定の大きさ内に冷却ユニットを配置して、外気（第１環境）を滑らかに冷却ユニット内へ吸気し、再び外気（第１環境）へ吹き出すことができる。さらに、本体ケース５ａは、内側板５ｂを下広がりに傾斜させて形成しているので、第１吸気口１１または第１吐出口１２から雨水が浸入してもこの傾斜面で雨水を取らえて下方に滴下させ、この傾斜面を吐出ガラリ７または吸込ガラリ６の下部に延設させることで、外気（第１環境）へ排出することができる。 The main body casing 5a is a front and inside to form the inner plate 5b in isosceles trapezoid shape in a rear, that which is formed by inclining the inside plate 5b below spread, the first discharge port that opens to the upper portion 12 and the first air intake port 11 can flow the air through the discharge gallery 7 and the suction gallery 6 disposed below and the cooling unit is arranged within a certain size in the cabinet 3. Outside air (first environment) can be smoothly sucked into the cooling unit and blown out to the outside air (first environment) again. Further, since the main body case 5a is formed by inclining the inner plate 5b so as to spread downward, even if rainwater enters from the first intake port 11 or the first discharge port 12, the inclined surface collects the rainwater and moves downward. It is possible to discharge to the outside air (first environment) by allowing the inclined surface to extend to the lower part of the discharge gallery 7 or the suction gallery 6.
