TECHNICAL FIELD

[0001] The present application relates to the technical field of water-cooled plate processing, in particular to a water-cooled plate processing method. BACKGROUND

[0002] With the development of servers, the scene of edge computing is becoming more and more complex, and is developing towards higher computing power and smaller volume, which means that the heat dissipation of electronic chips in unit volume or area will increase sharply. The traditional air-cooled natural and forced convection technology will be difficult to meet the heat dissipation needs of some edge servers, and the water-cooled plate heat dissipation technology needs to develop towards higher heat flux. The traditional water-cooled plate heat dissipation technology sets a metal plate between the heat-generating electronic device and the cooling liquid. The electronic device transmits heat to the metal plate through heat conduction, and the metal plate has a certain temperature equalizing effect. At the same time, the metal plate is internally designed with flow channels of different structures. The cooling liquid forms a convection heat exchange between the metal plate and the metal plate through the flow channels, thereby indirectly taking away the heat dissipation of the electronic device.
