Description

Technical Field

[0001] The invention belongs to the technical field of testing devices, and in particular relates to a universal water-cooled performance testing device. Background Art

[0002] VC liquid cooling plate is an efficient heat dissipation solution, which is widely used in high-performance electronic equipment, such as servers, high-performance computing equipment and high-end graphics cards. It uses liquid cooling technology to quickly transfer heat from the heat source to the heat dissipation area, thereby achieving a rapid cooling effect. After leaving the factory or after being used for a period of time, the VC liquid cooling plate needs to be tested for its performance through a general water-cooling performance test device to determine its usage status.

[0003] The existing general-purpose water-cooled performance test devices are designed, manufactured and assembled separately for each specification. This method has the following main disadvantages: a. It wastes a lot of designers’ time. It usually takes 1-2 days to design a set of test fixtures. b. Waste of production and use costs. Each fixture can only correspond to the corresponding specifications and cannot be shared with other specifications; c. Waste of technical personnel. Whenever a certain specification stops production and needs to be replaced, it takes a long time to disassemble and debug; d. Current test platforms all perform horizontal tests, but in fact some products may be at a certain angle after installation, which may cause certain differences in test results.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a universal water-cooled performance testing device to overcome the shortcomings in current practical applications. Summary of the invention

[0025] In this embodiment, the magnetic seat 7 can realize the rapid replacement of the first quick-change platform 51 and the second quick-change platform 8 by cooperating with or separating from the magnetic suction part, so as to facilitate the rapid and effective testing of different types of products, improve the testing range of the testing device, and further improve the flexibility and applicability of the device, thereby greatly shortening the adjustment time and speed when replacing the first quick-change platform 51 and the second quick-change platform 8.

[0026] like Figures 1 to 3 As shown, as a preferred embodiment of the present invention, the pressing mechanism 2 includes a pressing cylinder 21 and a limiting screw 22, the pressing cylinder 21 is installed on the second quick-change platform 8, and an adjusting mechanism 3 is fixed on the output end of the pressing cylinder 21, and the output end of the pressing cylinder 21 is intermittently matched with the limiting screw 22 fixed on the second quick-change platform 8, and the limiting screw 22 can limit the pressing stroke of the pressing cylinder 21, thereby controlling the downward movement stroke of the temperature sensing mechanism 4, while ensuring that the temperature sensing mechanism 4 is in full contact with the heat source, avoiding damage to the heat source by the temperature sensing mechanism 4, ensuring the accuracy of the test data, and the limiting screw 22 itself can be rotated and adjusted, so that the pressing stroke of the pressing cylinder 21 can be adjusted, and then the downward movement stroke of the temperature sensing mechanism 4 can be adjusted, so that the temperature sensing mechanism 4 can effectively test different types of heat sources, thereby improving the flexibility and practicality of the device.

[0027] like Figures 1 to 4 As shown, as a preferred embodiment of the present invention, the adjustment mechanism 3 includes a transverse adjustment rod 31, a longitudinal adjustment rod 33 and a butterfly locking piece 35, the transverse adjustment rod is fixed on the output end of the downward pressure cylinder 21, the transverse adjustment rod 31 is provided with a transverse adjustment groove 32, a longitudinal adjustment rod 33 is arranged above the transverse adjustment rod 31, a vertical adjustment groove 34 is provided on the longitudinal adjustment rod 33, a temperature sensing mechanism 4 is fixed at one end of the longitudinal adjustment rod 33, and the butterfly locking piece 35 can fix the longitudinal adjustment rod 33 and the temperature sensing mechanism 4 thereon to the transverse adjustment rod 31 by cooperating with the transverse adjustment groove 32 and the vertical adjustment groove 34.

The interior of the mounting tube 41 is hollow. The temperature sensing element is slidably installed at the bottom of the mounting tube 41. One end of the temperature sensing element extends into the mounting tube 41 and is connected to a spring in the mounting tube 41.

[0030] In this embodiment, the longitudinal adjustment rod 33 drives the temperature sensing element to move downward through the mounting tube 41 until it contacts the heat source. To ensure that the temperature sensing element can effectively contact the heat source, the longitudinal adjustment rod 33 will drive the mounting tube 41 to continue to move downward to a certain extent, so that one end of the temperature sensing element slides in the mounting tube 41, thereby compressing the spring in the mounting tube 41.

It achieves accurate temperature measurement by utilizing the thermoelectric effect, that is, the relationship between the electromotive force generated at the contact point of two different metals or alloys and the temperature.

Figure 1 It is a schematic diagram of the device in a horizontal state. Figure 6 This is a schematic diagram of the device in a vertical state.
