The water-cooled plate 106 absorbs the heat from the heat source, and the heat is taken away by the water-cooled liquid flowing through the inside of the water-cooled plate 106. Driven by the pump 103, the water-cooled liquid flows through the water tank 101, the water pump 103 and the heat exchanger 104 successively, and flows through the fan 105. Cooled by convective action with heat exchanger 104 , circulated back to water-cooled plate 106 . The main function of the water tank 101 is to facilitate the filling of water cooling liquid, store the cooling liquid, and shorten the emptying time of the liquid cooling system.

The existing liquid cooling system has an independent water tank. The water tank needs to occupy the space of the system. The water tank is connected to the heat exchanger, and the water tank and the pump through water pipes. The cost is high, and because there are many transfer nodes in the whole system, the system reliability ( Leakage) risk increases accordingly.
