When the server runs for a long time, a large amount of heat will be generated, and a circulating liquid cooling system is needed to cool the server.

[0003] After searching, a Chinese patent (application number "201220467601.X") discloses "a circulating liquid-cooled server heat dissipation system". The heat dissipation system includes a heat dissipation plate for assembly on a server, a fan mounted on the heat dissipation plate, and a liquid cooling device. The heat dissipation plate is provided with at least two heat dissipation holes, each heat dissipation hole is provided with a dehumidification device, and the liquid cooling device includes a cooling pipe loaded with liquid, a cooling water tank connected to one end of the cooling pipe, and a pump connected to the other end of the cooling pipe.
