Description

Technical Field

[0001] The invention relates to the field of testing devices, and in particular to an air tightness testing device for a water cooling plate and a process thereof. Background Art

[0002] A water-cooled plate, also known as a liquid-cooled plate or a water-cooled radiator, is a highly efficient heat dissipation device that is widely used in electronic products, computers, industrial equipment, and medical equipment. A water-cooled plate is a component that exchanges heat through liquid cooling. The principle is to form a flow channel in a metal plate, and the electronic components are installed on the surface of the plate (with a heat-conducting medium coated in the middle). The coolant enters from the inlet of the plate and exits from the outlet to take away the heat generated by the components.

[0003] After the water-cooled plate is produced, it is necessary to use an air-tightness testing device to test its air-tightness. Since the water inlet and outlet of the water-cooled plate both use universal sealing pipe threaded interfaces, when the water-cooled plate is tested by the air-tightness testing device, it is necessary to manually connect the air pipe to the air inlet and outlet of the water-cooled plate with the air port of the testing device through the sealing pipe threaded interface. The connection process is relatively cumbersome. When testing a large number of water-cooled plates, the workload of the personnel is large, resulting in low test efficiency. Moreover, if the threaded connection is tight, it is not convenient to disassemble after the test is completed. If the threaded connection is loose, the sealing after the connection cannot be guaranteed. That is, the existing air-tightness testing device has the defect that the water inlet and outlet of the water-cooled plate cannot be quickly connected to the air pipe.
