[0137] When the heat generated by the operation of the collector device is absorbed by the second end of the heat exchange element 111 and conducted to the first end, the temperature of the air inside the gas flow element 121 rises, and the air with lower external temperature flows into the gas flow element 121 from below (chimney effect), and the air flow carries away the heat of the first end of the heat exchange element 111.

[0138] The temperature monitoring unit 160 monitors the temperature of the collector device:

[0142] When the temperature of the collector device is higher than 40℃ and lower than or equal to 50℃, the temperature monitoring unit 160 sends a signal to the control unit 170, and the control unit 170 controls the flow regulating unit 150 to operate at the rated power.

[0143] The advantages of the present application are that by setting a heat exchange unit on the back side of the collector device, a gas flow-through unit is vertically set on the heat dissipation end of the heat exchange unit, the chimney effect is used to accelerate the heat dissipation of the heat exchange unit, and a temperature monitoring unit is set to monitor the temperature of the collector device, and a flow regulating unit is set to accelerate the fluid according to different conditions, which can effectively avoid the problem of easy blockage of the ventilation opening in harsh environments to ensure normal heat dissipation of the collector device, while reducing energy consumption, and solving the problem of short service life of the equipment caused by easy blockage of the heat dissipation opening of the collector in harsh environments.
