The invention relates to a water-filling and degassing structure of a water-cooling device, in particular to a water-filling and degassing structure of a water-cooling device which can simply perform water-filling and degassing work on a water-cooling device.

In recent years, water-cooling devices have been widely used in high-power heat sources for heat dissipation. Because of their better heat dissipation efficiency, they are widely used in industrial computer or server system cabinets or transportation vehicles or lighting equipment. For the heat dissipation, the water-cooling device is mainly composed of a water-cooled head, a pump, and a water-cooled row. The units are connected in series by a pipe body, and the water-cooling head mainly performs heat-absorbing work. The water-cooling head has a water-capacity chamber. One side of the water-receiving chamber is open, and a heat exchange dielectric panel made of a thermally conductive good conductor is disposed to close the water-receiving chamber, and the heat exchange interface panel is opposite to one side of the water-receiving chamber The heat generated by the heat source is directly attached to a heat source, and the heat exchange medium panel further transfers heat to one side of the heat exchange dielectric panel body corresponding to the water receiving chamber, and the side is provided with a plurality of heat dissipation a fin, the water-receiving chamber is filled with a cooling liquid (such as pure water, ethanol, refrigerant, etc.) for performing a cooling cycle, and the cooling liquid exchanges heat to the heat-dissipating fins. The cooling liquid used in the internal cooling cycle can be smoothly cooled. The cooling liquid is mainly pushed by the pump, and the cooling liquid is discharged from the water cooling head and then enters the water cooling row for cooling. Finally, the cooling liquid is cooled in the water cooling row. Re-enter the water-cooled head for a cooling cycle.
