The embodiment of the invention provides a cooling device, a control method and a machine room. The problem that a heat exchanger can be easily damaged by accumulated ice cubes when operating in winter is solved. The cooling device of the embodiment comprises a heat exchanger with a first heat exchange channel, and a first air control module for controlling the circulating of air flow in the firstheat exchange channel, wherein the first air control module comprises an air inlet valve, an air outlet valve, a switching air valve, a first draught fan, a second draught fan and a butt joint port for butt joint with the first heat exchange channel, when the air inlet valve is switched off, the air outlet valve is switched on and the switching air valve is switched on, the first draught fan andthe second draught fan are used for discharging the air flow in the first heat exchange channel through the air outlet valve, and when the air inlet valve is switched on, the air outlet valve is switched off and the switching air valve is switched off, the second draught fan is used for guiding the air flow into the first heat exchange channel through the air inlet valve. By means of the cooling device of the embodiment, the forward circulating and reverse circulating of the air flow in the first heat exchange channel can be realized, and the structure of the heat exchanger is prevented from being damaged by accumulated ice cubes in the heat exchanger.
Description
technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device, a control method and a machine room. Background technique [0002] With the widespread popularization of Internet technology, the load of the data center computer room is getting heavier, and its heat dissipation performance has become particularly important. [0003] In the prior art, in order to reduce the energy consumption of the computer room for heat dissipation, some use indirect heat exchangers for heat dissipation, that is, the external cold air and the hot air in the computer room exchange heat through the heat exchanger, thereby reducing the temperature of the computer room. Purpose. [0004] However, when the outside air temperature is lower than 0°C, condensed water may freeze in the heat exchanger in the prior art, and the ice cubes will accumulate, causing the heat exchanger to be blocked or even damaged, which seriously affects Improve the ...
