In addition, an outside air inlet 8 is provided on one side of the heat exchange device 3 and an outside air outlet 9 is provided on the other side. Inside the heat exchange device 3, a heat exchanger 10, a first blower fan 11, and a second blower fan 12 are provided.

  FIG. 3 is a cross-sectional view of the heating element storage device. Although this heating element storage device has been described with reference to FIG. 1, a heating element case 2 containing a transmitter / receiver and a heat exchange device 3 are accommodated inside a cabinet 1 serving as an outer shell. On the top surface of the heating element case 2, an inside air exhaust port 13 that fits into the inside air suction port 6 of the heat exchange device 3 is provided. (Not shown in FIG. 3, not shown in FIG. 5) An inside air outlet duct 14 is provided below the inside air outlet 7 of the heat exchanger 3.

  In the heating element storage device having such a configuration, the heat generated by the transmitter / receiver increases the temperature of the air in the heating element case 2. The warmed air is sucked into the heat exchange device 3 from the inside air exhaust port 13 (the inside air suction port 6) by the operation of the first blower fan 11. On the other hand, by the operation of the second blower fan 12, cold air outside the heating element storage device, that is, outside air is sucked into the heat exchange device 3 through the outside air inlet 4 and the outside air inlet 8. Here, the heat exchanger 10 is configured by laminating plates having flow paths through which air passes, and each of air having a temperature difference from two directions is guided and heat is generated between the air. Exchange. After the inside air and the outside air respectively flow into the heat exchanger 10 and perform heat exchange, the cooled inside air is blown out from the inside air blowing port 7 to the heating element case 2 through the inside air blowing duct 14. On the other hand, the outside air warmed by heat exchange is discharged outside the heating element storage device through the outside air outlet 9 and the outside air outlet 5.

  In such a heating element storage device, as shown in FIG. 4, the heat exchanging device 3 is attached so as to be inserted into the installation place at the top of the heating element case 2 with the door 15 of the cabinet 1 being opened. This attachment method will be described with reference to FIGS.

  An inside air exhaust port 13 is provided on the top surface of the heating element case 2 along the side on the back side in the insertion direction. Similarly, a case side rail 16 is provided on the top surface of the heating element case 2 from the front side in the insertion direction of the heat exchange device 3 and extends toward the inside air exhaust port 13. As shown in FIG. 5, a flat portion 17 is provided between the end of the case side rail 16 on the side of the room air exhaust port 13 and the room air exhaust port 13. The length of the flat portion 17 is L, and this length L is the distance between the end of the case side rail 16 and the inside air exhaust port 13. On the other hand, a cooling device side rail 18 shorter than the length L of the flat portion 17 is provided on the bottom surface of the heat exchange device 3 in parallel with the insertion direction of the heat exchange device 3. The inside air exhaust port 13 provided in the heating element case 2 has a peripheral edge raised toward the heat exchange device 3 side. (Case side rising part 23) The packing 19 is affixed around the periphery. Moreover, the inside air suction port 6 provided in the heat exchange device 3 is an opening larger than the inside air suction port 6 so that the inside air exhaust port 13 is fitted therein.

  In such a configuration, the heat exchanging device 3 is first placed in the vicinity of the entrance of the installation place so that the cooling device side rail 18 is placed on the case side rail 16. (State in FIG. 5) Next, the heat exchange device 3 is slid back along these rails (the case side rail 16 and the cooling device side rail 18). The cooling device side rail 18 protrudes from the case side rail 16 and finally falls from the case side rail 16 to the flat portion 17. The length of the cooling device side rail 18 is made shorter than the length L of the flat portion 17 so that the cooling device side rail 18 falls into the flat portion 17. When this falls, the inside air exhaust port 13 and the inside air suction port 6 are fitted. At this time, the packing 19 affixed to the peripheral portion of the inside air exhaust port 13 and the peripheral portion of the inside air suction port 6 of the heat exchange device 3 are joined to ensure airtightness.

  In this way, the heat exchanging device 3 can be easily attached to the heat exchanging device 3 having a considerable weight in some cases by sliding the cooling device side rail 18 on the case side rail 16 and attaching it. . Further, since the cooling device side rail 18 falls into the flat portion 17, the positioning becomes possible, and fine adjustment of the fixed position is unnecessary. Furthermore, since the inside air exhaust port 13 on the heating element case 2 side and the inside air suction port 6 on the heat exchange device 3 side can be fitted at once, easy attachment can be realized.

  In the opening portion of the inside air suction port 6 provided on the heat exchange device 3 side, it is preferable to raise the peripheral portion toward the inside of the heat exchange device 3. (Cooling device side rising portion 24) By providing such a cooling device side rising portion 24, it is possible to suppress intrusion of rainwater or the like from the fitting portion between the inside air suction port 6 and the inside air exhaust port 13.

  In addition, by providing the case side rail 16 in a state protruding from the case on the near side in the insertion direction, positioning can be easily performed when the cooling device side rail 18 is placed on the case side rail 16.

  Furthermore, the end of the case side rail 16 on the side of the inside air exhaust port 13 is inclined toward the flat portion 17, and the end of the heat exchanger 3 opposite to the inside air inlet 6 of the cooling device side rail 18 is provided. An inclined part is provided toward the main body. With this configuration, the cooling device side rail 18 can be smoothly moved when dropped into the flat portion 17.

  Moreover, as shown in FIGS. 6 and 7, a flange 20 is provided at the insertion port of the heat exchange device 3 of the cabinet 1, and is joined to the flange 20 when the heat exchange device 3 is attached to the regular mounting position. A flange 21 having a bowl shape is provided. A packing 22 is affixed to the joint surface between the flange 20 and the flange 21. (In FIG. 6, an example of attaching to the flange 20 side is shown.) Further, the thickness of the cooling device side rail 18 is made thinner than the thickness of the case side rail 16. By adopting such a configuration, the upper portion of the flange 20 and the flange 21 are tightly joined, and the lower portion is weakly joined. According to such a configuration, the heat exchange device 3 is attached with an inclination that is lowered toward the back side in the insertion direction, and the joining pressure due to its own weight can be increased at the joining surface between the flange 21 and the flange 20. Further, since pressure due to its own weight is also applied to the joint portion between the inside air suction port 6 and the inside air exhaust port 13, the airtightness can be improved.

  As described above, the present invention includes a heating element case that houses a heating element therein, and a cooling device that is mounted on the heating element case and cools heat generated from the heating element. The top surface is provided with a case-side convex portion, an exhaust port, and a flat portion between the case-side convex portion and the exhaust port, and on the bottom surface of the cooling device, the cooling device-side convex portion, the suction port, The cooling device is configured to be installed on the top surface of the heating element case so that the convex portion on the cooling device side fits in the flat portion, and the exhaust port fits into the suction port. Since the cooling device is arranged on the upper part of the body case, the installation area of the heating element storage device can be reduced accordingly. Also, the cooling device side convex portion is slid on the case side convex portion and moved to the mounting position, and the cooling device side convex portion is dropped into the flat portion and attached. There is an effect that is easy. Therefore, for example, it is extremely useful as a cooling facility for a communication device base station installed in a place where the installation area is restricted, such as a rooftop of a building in an urban area, or other outdoor installation equipment.
