Embodiments of the present invention provide a heat dissipation device, a control method, and a machine room to solve the problem that the heat exchanger is easily damaged due to the accumulation of ice cubes during winter operation; the heat dissipation device in the embodiment of the present invention includes a heat exchanger, and the heat exchanger has a first A heat exchange channel; the first air control module is used to control the flow of air in the first heat exchange channel; the first air control module includes an air inlet valve, an air outlet valve, a switching air valve, a first fan and a second fan, and The docking port connected to the first heat exchange channel; wherein, when the air inlet valve is closed, the air outlet valve is opened, and the switching air valve is opened, the first fan and the second fan are used to transfer the airflow in the first heat exchange channel from the outlet Valve discharge; when the air inlet valve is opened, the air outlet valve is closed, and the switching air valve is closed, the second blower is used to introduce the air flow from the air inlet valve into the first heat exchange channel. The heat dissipation device of the embodiment of the present invention can realize the forward circulation and reverse circulation of the airflow in the first heat exchange channel, and avoid the accumulation of ice cubes in the heat exchanger and damage the structure of 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 ...
