After the cooling liquid is pumped out from the cooling liquid tank, first enter liquid inlet shell 7, then enter liquid inlet shell 7 through the middle flat plate shell 7, and finally circulate in circulating liquid cooling pipe 2 and then discharge to the cooling liquid tank. In this process, the air in the cooling liquid gradually separates from the cooling liquid in the height difference formed by the liquid outlet shell 5, the hollow flat plate shell 6 and the liquid inlet shell 7, and finally concentrates on the top of the liquid inlet shell 7 and is discharged through the exhaust valve 9. After the cooling liquid circulates for a period of time, the circulating liquid cooling pipe 2 will be completely filled with cooling liquid, ensuring the contact of the cooling liquid with the heat conduction assembly and the cooling efficiency of the entire cooling radiator.

[0024] The liquid inlet pipe is close to the liquid inlet of the circulating liquid cooling pipe 2, and the liquid outlet pipe is close to the liquid outlet of the circulating liquid cooling pipe 2. The liquid outlet pipe of the cooling liquid tank is connected to the liquid inlet pipe of the circulating liquid cooling pipe 2 through the liquid inlet valve 8, and the liquid outlet of the circulating liquid cooling pipe 2 is connected to the liquid inlet pipe of the cooling liquid tank. Under the pumping action of the pump, the cooling liquid circulates through the circulating liquid cooling pipe 2, and the cooling liquid that absorbs heat in the process is cooled through the cooling liquid tank. A part is cooled through the cooling fan 3, and a part is cooled through the large area of the hollow flat shell 6 in contact with the air, so as to ensure that the temperature of the cooling liquid entering the hollow bottom shell 10 is lower than the temperature of the CPU.
