- the case 2 will be installed on the case top surface 74 in the state which inclined the suction inlet 48 side below. As a result, the pressure at which the air outlet 70 and the suction port 48 are joined is increased by the dead weight of the case 2, and the airtightness is improved.
- the attachment on the case 32 is easy even if the heat exchange device 33 is heavy.
- the heat exchange device is used for the heating element storage device.
- Two flows are formed: a first fluid flowing inside and outside the heating element storage device and a second fluid circulating in the heating element storage device.
- the first fluid sucked from the first suction port passes through the heat exchanger and is then blown out from the first blower outlet provided in the horizontal direction by the first blower.
- the second fluid sucked from the second suction port passes through the heat exchanger and is then blown out from the second blower outlet provided in the vertical direction by the second blower.
- the heat generated in the heating element storage device is carried to the heat exchanger by the second fluid.
- the second fluid that has radiated heat to the first fluid in the heat exchanger is circulated into the heating element storage device.
- the first fluid that has absorbed heat by the heat exchanger is blown out of the heating element storage device. Therefore, the heat generated in the heating element storage device is released to the outside of the heating element storage device.
- the first fluid sucked by the first blower through the heat exchanger is blown out from the first blowout port.
- the second fluid that exchanges heat with the first fluid through the heat exchanger is sucked into the heat exchanger by the second blower.
- the 2nd fluid heat-exchanged with the heat exchanger is blown off from the 2nd blower outlet by the 2nd air blower.
- the heat exchange device and the heating element storage device according to the present invention are extremely useful as a cooling facility for a communication device base station installed in a place where the installation area is restricted, such as the rooftop of a building in an urban area, and other outdoor installation devices. It will be a thing.
