[0033] A convenient airtightness testing device is used to detect the airtightness of a workpiece 300 to be tested. The workpiece 300 to be tested mainly refers to a water-cooled plate. A water-cooled plate usually has at least one water inlet and one water outlet. There are multiple water channels inside the water-cooled plate or the water-cooled plate is connected by a copper tube, an aluminum tube, and a three-way joint. This can give full play to the advantages of water cooling and take away more heat. After the water-cooled plate is processed and manufactured, an airtightness testing device is required to perform an airtightness test on the overall cooling water channel of the water-cooled plate to ensure that the water-cooled radiator does not leak and enhance stability during use.

[0034] See also Figure 1-6 As shown, the portable airtight testing device comprises: an airtight testing mechanism 100, a linear slide rail 200 and a base plate 600, wherein the base plate 600 serves as a carrier of the entire portable airtight testing device.

[0035] The structure of the substrate 600 can be various. In this embodiment, the substrate 600 is a plate-shaped structure. The linear guide rail 200 is fixed on the substrate 600. The airtight test mechanism 100 is installed on the linear guide rail 200 through the slider 210 and is driven by the driving mechanism 400 to move along the linear guide rail 200.

[0036] The substrate 600 is provided with an inspection station 610 for assembling the inspected workpiece 300. Here, the inspection station 610 is provided as a groove, and the inspected workpiece 300 is sunk into the inspection station 610 to have a certain limiting effect.

[0037] The airtight testing mechanism 100 has a first interface 101 and a second interface 102, the first interface 101 and the second interface 102 are connected; a sealing ring 103 is provided on the inner wall of the first interface 101, and a valve assembly 130 is provided in the second interface 102;

[0038] The airtight test mechanism 100 is driven by the driving mechanism 400 to move along the linear guide rail 200 close to the workpiece 300 to be tested, so that the joint 310 of the workpiece 300 to be tested is plugged into the first interface 101 , and the joint 310 and the first interface 101 are sealed by the sealing ring 103 .

[0039] In this embodiment, the sealing ring 103 is set to be circular. In other embodiments, the sealing ring 103 can be set to other shapes. The shape of the sealing ring 103 is related to the joint 310 of the workpiece 300 to be inspected. Depending on the size and shape of the joint 310, the sealing ring 103 may also be set to an O-type, a hollow cylinder, a stepped shape, etc., as long as the joint 310 can be sealed after being plugged into the first interface 101.

[0040] like Figure 1 , Figure 4 and Figure 6 As shown, Figure 6 The workpiece 300 to be inspected is a water-cooled plate, and the water-cooled plate has two joints 310;

[0041] Accordingly, two groups of airtight detection mechanisms 100 are provided, and one joint 310 corresponds to one group of airtight detection mechanisms 100;

[0042] The two sets of airtight detection mechanisms 100 can be driven to move by the same driving mechanism 400, or can be driven to move by two sets of driving mechanisms 400 respectively.

[0043] like Figure 4 As shown, the two sets of airtight detection mechanisms 100 are pushed to move leftward by the driving mechanism 400, and the joint 310 of the detected workpiece 300 is plugged into the first interface 101;

[0044] When testing air tightness, the air tightness testing mechanism 100 of the first group is connected to the air source, and the air tightness testing mechanism 100 of the second group is not connected to the air source;

[0045] The airtight detection mechanism 100 of the first group is connected to an external gas source and gas is introduced, the valve assembly 130 is triggered by the pressure of the external gas source connector, and after the valve assembly 130 moves down, the second interface 102 is opened, and the gas enters from the second interface 102, flows into the first connector 310 through the first interface 101, and then the gas flows along the pipeline in the water-cooled plate, flows to the second connector 310 of the water-cooled plate, and then flows into the first interface 101 of the airtight detection mechanism 100 of the second group, and finally flows to the second interface 102 of the airtight detection mechanism 100 of the second group. The force applied to the valve assembly 130 in the airtight detection mechanism 100 of the second group makes the valve assembly 130 more tightly pressed against the second interface 102 of the airtight detection mechanism 100 of the second group, so that the airtightness of the water-cooled plate can be detected.

[0046] That is, among the two groups of airtight detection mechanisms 100, one group of airtight detection mechanisms 100 is used as a sealing plug, and the other group of airtight detection mechanisms 100 is connected to an external air source.

[0047] In addition, the airtight detection mechanism 100 can be connected to pressure detection equipment, vacuum box helium detection equipment, etc. to detect the specific pressure value of the equipment and determine whether there is a leak based on the specific pressure value.

[0048] like Figure 4 and Figure 6 As shown, in this embodiment, the workpiece 300 to be inspected, that is, the water-cooling plate, is provided with two joints 310. It is also possible that the workpiece 300 to be inspected is provided with three joints, and the three joints are connected through the pipeline inside the workpiece 300 to be inspected.

The triangular elastic buckle 133 fixes the valve stem 131. When the valve stem 131 is subjected to the pressure of the external gas source connector, the spring 132 is compressed when the valve stem 131 moves downward, and the sealing ring a1311 leaves the inner wall of the second interface 102, so that the second interface 102 is opened, and the gas can enter the second interface 102; after the external gas source connector is disassembled, the valve stem 131 is reset and moved upward under the elastic force of the spring 132, and the second interface 102 is closed.
