The lifting drive assembly 3 can also be electrically connected to the controller. The number of pressure columns 41 can be set according to actual needs, and multiple pressure columns 41 arrays are installed on the bottom surface of the support plate 4. The water-cooled support platform 2 is provided with cooling water channels, which can be connected to an external power pump, etc., via water pipes. The water-cooled support platform 2 can be made of materials with good thermal conductivity, such as aluminum alloy, and the top surface of the water-cooled support platform 2 can be coated with thermally conductive paste. The component to be tested 100 includes, but is not limited to, circuit boards.

[0022] Specifically, the test piece 100 is placed on the water-cooled support platform 2. The conductive component 1 is electrically connected to the test piece 100. The lifting drive component 3 drives the support plate 4 and the pressure column 41 to move downwards until the pressure column 41 presses the test piece 100 onto the water-cooled support plate 4. During the testing process, the water-cooled support platform 2 can cool the test piece 100 from the bottom. In this invention, the water-cooled testing device uses water cooling to cool the test piece 100, improving the cooling efficiency of the device and making it easy to operate. Furthermore, the pressure column 41 presses the test piece 100 onto the water-cooled support platform 2, ensuring a tight fit between the test piece 100 and the platform, further improving the cooling efficiency.

[0026] In one embodiment, such as Figure 3 As shown, the conductive component 1 includes a support block 11, a sliding column 12, an elastic element 13, and a conductive block 14; the support block 11 is provided with a sliding hole (not shown in the figure), the sliding column 12 is slidably inserted into the sliding hole, the conductive block 14 is mounted on the sliding column 12, and the elastic element 13 is sleeved on the sliding column 12 and abuts against the support block 11; the conductive block 14 is electrically connected to the controller, and the conductive block 14 is used to electrically connect to the test piece 100 on the water-cooled support platform 2.

[0028] Specifically, when the test piece 100 is placed on the water-cooled support platform 2, the test piece 100 will press down on the conductive block 14, and the conductive block 14 will drive the guide post 21 to move down and compress the elastic member 13. The rebound force of the elastic member 13 can make the conductive block 14 and the test piece 100 in close contact, ensuring the stability of the electrical connection between the conductive block 14 and the test piece 100.

[0029] In one embodiment, such as Figure 3As shown, the conductive component 1 further includes a lifting drive 15, and the support block 11 is installed at the output end of the lifting drive 15; the lifting drive 15 is used to drive the conductive block 14 to move up and down through the support block 11, so that the conductive block 14 contacts or moves away from the test piece 100 on the water-cooled support platform 2.

[0030] The lifting drive component 15 includes, but is not limited to, pneumatic cylinders, hydraulic cylinders, and linear motors.

[0031] In this embodiment, the lifting drive 15 can drive the conductive block 14 to rise and fall, further ensuring the stability of the electrical connection between the conductive block 14 and the test piece 100.

External air can enter the groove space 63 through the ventilation hole. The ventilation hole and the opening are located on opposite sides of the groove space 63, so that the gas in the groove space 63 can form convection, which further improves the cooling efficiency of the water-cooled testing device for the test piece 100.

[0045] In one embodiment, such as Figure 1 As shown, the water-cooled detection device also includes an alarm light 65 installed on the top of the chassis 6, and the alarm light 65 is electrically connected to the controller.
