With the continuous improvement of people's requirements for the performance, space and style of electronic equipment, the application field of liquid cooling plates will be further expanded. In order to ensure the normal operation of the liquid cooling plate, it is necessary to test whether its heat dissipation performance meets the requirements.

[0021] The technical solutions in the present invention will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 and Figure 2 A preferred embodiment of a liquid cooling plate test fixture with multiple heat sources in different directions is shown, which includes a placement rack 1, multiple heating blocks 2 and multiple liquid cooling plates 3; the placement rack 1 has test support areas in multiple directions, and a test base 4 is respectively installed on the test support area in each direction, and each test base 4 is provided with multiple assembly grooves 41, and each assembly groove 41 is respectively fixedly installed with a heating block 2. Each test base 4 is respectively fixedly installed with a liquid cooling plate 3 located on two sides of the heating block, and the liquid cooling plates 3 on the test support areas in multiple directions are connected by pipelines 5.

[0023] In this embodiment, the placement rack 1 has a horizontal test support area and a vertical test support area. The horizontal test support area is provided with a horizontal limit structure, and the vertical test support area is provided with a vertical support structure.

[0024] The horizontal limiting structure includes limiting corner blocks 11 arranged at four corners of the test support area in the horizontal direction. The test base 4 is supported on the test support area in the horizontal direction and is limited by the limiting corner blocks 11 .

[0025] The vertical support structure includes two support blocks 12 arranged on both sides of the test support area in the vertical direction. Support grooves 42 are provided on both sides of the test base 4. The test base 4 is supported on the test support area in the vertical direction of the placement rack 1 by the cooperation between the support grooves 42 and the support blocks 12.

[0026] Furthermore, in order to achieve more stable lateral positioning, the upper end of the support block 12 has a step embedding opening 121, and the support groove 42 has an embedding platform 421 that cooperates with the step embedding opening 121 of the support block 12. When the test base 4 is supported on the vertical test support area of ​​the placement rack 1 through the cooperation of the support groove 42 and the support block 12, the embedding platform 421 on the support groove 42 of the test base 4 is embedded in the step embedding opening 121 of the support block 12.

[0027] In order to measure the temperature, a temperature sensing wire is provided on the heating block 2 .

[0028] Furthermore, the test base 4 is a bakelite base; and the pipeline 5 is a rubber tube.

[0029] During assembly and testing, the heating blocks 2 are fixedly assembled in the assembly grooves 41 of the test base 4, and the liquid cooling plate 3 is fixedly assembled on the test base 4. According to the above steps, two groups of components are assembled, and then one group of components is horizontally assembled on the horizontal test support area of ​​the placement rack 1, and is limited by four limiting corner blocks 11, and the other group of components is assembled on the vertical test support area of ​​the placement rack 1, and is positioned and supported by the vertical support structure. The horizontal liquid cooling plate 3 and the vertical liquid cooling plate 3 are connected by pipeline 5.

[0030] When the power is turned on, the heating block 2 generates heat, and the heat source is transferred to the liquid cooling plate 3 directly above it. The temperature of a certain point on the liquid cooling plate 3 in two directions is measured by the temperature sensing line, and then the cooling medium is passed to the liquid cooling plate 3 in the horizontal direction. After the cooling medium flows in the chamber in the liquid cooling plate 3 in the horizontal direction, it passes through the pipeline 5 and then enters the chamber of the liquid cooling plate 3 in the vertical direction. The temperature of the corresponding points of the liquid cooling plates 3 in the two directions is detected again to determine the heat dissipation effect.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
