[0057] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner. Therefore, only the components related to the present application are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation may be arbitrarily changed, and the layout type of the components may also be more complex.

[0058] With the wide application of electronic devices and mechanical systems in modern society, as a key thermal management component, the performance of the radiator directly affects the operating efficiency, stability, and service life of the device. In order to test the heat dissipation performance of the radiator, in the prior art, a radiator test fixture structure is often used as a device specifically for evaluating the performance of the radiator, so as to provide an important basis for the design optimization and quality control of the radiator. However, the existing radiator test fixture structures often only support the installation of single-specification radiators, with poor compatibility, and it is not easy to adjust the position of the radiator in the fixture, which causes inconvenience to the test and affects the test efficiency.

[0059] The following embodiments of the present application provide a radiator test fixture for improving the compatibility and test efficiency of radiator tests. The principle and implementation manner of a radiator test fixture in this embodiment will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can understand the radiator test fixture of this embodiment without creative labor.

[0060] As Figure 1 and Figure 2As shown in the figure, this embodiment provides a radiator test fixture 1, which is stably placed on a workbench 2. The workbench 2 provides a solid foundation for the entire test device, ensuring that the radiator test fixture 1 can remain stable during the test, thereby improving the accuracy and reliability of the test results. A baffle 3 is externally connected to the wind tunnel side of the radiator test fixture 1. The design of the baffle 3 plays a key role. It can not only effectively guide the direction of the air flow but also prevent external interference factors from affecting the test results, creating a relatively closed and stable test environment for the radiator test. The radiator test fixture 1 is tightly connected to the baffle 3 through the mounting opening 31 on the baffle 3, which not only ensures the firmness of the connection but also facilitates installation and disassembly, improving the usability of the test fixture. During the test, the air flow enters the interior of the radiator test fixture 1 through the wind tunnel side, simulating the heat dissipation conditions faced by the radiator in the actual use environment, enabling the test results to truly reflect the performance of the radiator in the actual application scenario and providing valuable data support for the design optimization and quality assessment of the radiator.

[0061] As Figures 3 to 9 shown in the figure, the radiator test fixture 1 provided in this embodiment includes: a radiator 11, a test board 12, and a base 13.

[0062] One side of the test board 12 is provided with mounting holes 121, which are specifically designed fixed mounting points for the radiator 11. Through the mounting holes 121, the radiator 11 can be firmly mounted on the test board 12, thereby ensuring the stability of the radiator 11 during the test and making the contact between the radiator 11 and the test board 12 closer, thus ensuring the accurate measurement of the heat dissipation effect.

[0063] Furthermore, the design of the test board 12 takes into account the adaptation requirements of different specifications of radiators 11. It can support a variety of different specifications of mounting holes 121, which means that whether it is a small, medium, or large radiator, it can be fixed on the test board 12 through the corresponding mounting holes 121. This diverse adaptation ability greatly improves the compatibility of the heat dissipation test, enabling the same test board 12 to be used for the test of multiple radiators, reducing the repeated purchase cost of test equipment, and improving the test efficiency.

[0064] As Figure 5As shown, there are mounting hole positions for four types of radiator specifications, namely A, B, C, and D, on the test board 12. These mounting hole positions respectively correspond to radiators 11 of different specifications, ensuring that each radiator can find a suitable mounting position. For example, the mounting hole positions of specification A are suitable for small radiators, those of specification B are suitable for medium-sized radiators, while specifications C and D are respectively adapted to larger-sized radiators. Through this hierarchical design, the test board 12 can meet the mounting requirements of radiators of different sizes, thereby realizing the performance test of different types of radiators.

[0065] After the radiator 11 is fixed to the test board 12 through the mounting hole positions 121, heat dissipation can be carried out on the heating block 4 on the test board 12. The heating block 4 generates heat during the test process, and the radiator 11 quickly conducts and dissipates this heat to simulate the heat dissipation effect of the radiator on the heating element in the actual use scenario. In this way, the heat dissipation performance of the radiator 11, including key indicators such as heat dissipation efficiency and thermal resistance, can be accurately evaluated.

[0066] It should be noted that the design of the test board 12 provided in the embodiments of the present application has a high degree of flexibility, and the present application does not impose any restrictions on the number and specifications of the mounting hole positions. According to the actual test requirements, the test board 12 can also be provided with more mounting hole positions 121, thereby ensuring the long-term applicability of the radiator test fixture 1 and enabling the radiator test fixture 1 to adapt to the continuously changing radiator test requirements.

[0067] Furthermore, as Figure 4 shown, there are fixing nuts 122 on the mounting hole positions 121, and the radiator 11 is fixed to the test board 12 by threadedly connecting the radiator screws 111 with the fixing nuts 122. When the radiator screws 111 are screwed into the fixing nuts 122, the threads of the two are tightly engaged, thereby firmly fixing the radiator 11 on the test board 12. This threaded connection method also has good adjustability and can be appropriately adjusted according to the size and shape of the radiator 11 to ensure that the contact surface between the radiator 11 and the test board 12 is closely fitted, thereby improving the heat dissipation efficiency.

[0068] In addition, by using the combination of the radiator screws 111 and the fixing nuts 122, the installation and disassembly process of the radiator 11 becomes more convenient. After the test is completed, simply loosen the radiator screws 111, and the radiator 11 can be easily disassembled from the test board 12, facilitating subsequent tests or other operations. This not only improves the test efficiency but also reduces the test errors caused by improper installation, ensuring the accuracy and reliability of the test results.

[0069] Furthermore, as Figures 4 to 8As shown, a hollow cylindrical magnet 123 is provided on the other side of the test board 12, and a slide rail 131 is provided on the base 13. The cylindrical magnet 122 is snapped into the slide rail 131 to adjust the position of the test board 12 in the first direction, the second direction, and / or the third direction. Among them, the first direction, the second direction, and the third direction are perpendicular to each other in pairs.

[0070] Further, since the cylindrical magnet 123 is snapped into the slide rail 131, therefore, as Figure 4 and Figure 8 shown, when the cylindrical magnet 123 slides in the chute 1313 of the slide rail 131, the test board 12 will correspondingly adjust its position in the first direction. Also, since the radiator 11 and the test board 12 are fixedly connected, therefore, the radiator 11 can also adjust its position in the first direction.

[0071] Further, as Figure 7 shown, a rivet post 124 is provided on one side of the test board 12, and a screw 125 passes through the cylindrical magnet 123 and is screwed into the rivet post 124 to fix the cylindrical magnet 123 to the other side of the test board 12. During installation, the screw 125 passes through the central hole of the cylindrical magnet 123 and then is precisely screwed into the rivet post 124. This installation method utilizes the thread fit between the screw 125 and the rivet post 124. By tightening the screw 125, the cylindrical magnet 123 can be firmly fixed on the other side of the test board 12.

[0072] Further, as Figures 4 to 6 shown, when the height of the cylindrical magnet 123 changes, the test board 12 will adjust its position in the third direction. That is, the cylindrical magnet 123 can be replaced with a different height according to needs and fixed to the other side of the test board 12. At this time, the test board 12 will adjust in the third direction due to the height change of the cylindrical magnet 123. Also, since the radiator 11 and the test board 12 are fixedly connected, therefore, the radiator 11 can also adjust its position in the third direction.

[0073] As Figure 8 and Figure 9 shown, multiple rows of equally spaced fixing posts 132 are riveted on both sides of the base 13. Both sides of the slide rail 131 are provided with stud bolts 1311 and positioning posts 1312. The positioning posts 1312 are used to move the slide rail 131 to different specified positions to connect the stud bolts 1311 with the corresponding fixing posts 132, so as to fix the slide rail 131 to the base 13.

[0074] That is, as Figure 8 and Figure 9As shown, the base 13 is riveted with multiple rows of equally spaced fixing posts 132 in the second direction. Each row of fixing posts 132 includes an inner fixing post and an outer fixing post. In fact, the inner fixing post is used to cooperate with the positioning post 1312 to determine that the stud 1311 can be accurately connected to the outer fixing post, so as to fix the slide rail 131 on the base 13.

[0075] Moreover, since the base 13 is riveted with multiple rows of equally spaced fixing posts 132 in the second direction, the slide rail 131 can actually move to different specified positions in the second direction, so that the stud 1311 is connected to the corresponding fixing posts 132 in this row, thereby realizing the movement of the slide rail 131 at different positions on the base 13. Furthermore, when the fixed position of the slide rail 131 on the base 13 changes, the test board 12 makes a position adjustment in the second direction.

[0076] Furthermore, as Figure 8 shown, a first direction scale C1 and a second direction scale C2 are provided on the base 13. The first direction scale C1 is used to mark the position adjustment amount of the test board 12 in the first direction, and the second direction scale C2 is used to mark the position adjustment amount of the test board 12 in the second direction. Through the first direction scale C1 and the second direction scale C2, it is possible to conveniently and accurately control the position change amount of the test board 12 (radiator 11).

[0077] Furthermore, as Figure 3 shown, the radiator test fixture 1 provided in this embodiment further includes an upper cover 14 and a front panel 15. Among them, the upper cover 14 is fixedly connected to the base 13 by a first screw; the front panel 15 is fixedly connected to the base 13 by a second screw.

[0078] Furthermore, as Figure 1 and Figure 3 shown, a wire passing hole 133 is provided on the side of the base 13. The wire passing hole 133 is for the thermocouple wire to pass through for external connection to devices such as a console and a display device.

[0079] In summary, the radiator test fixture provided by this application can support radiators of different specifications through the settings of the mounting holes on the test board, with strong expandability. Only the radiator to be tested needs to be replaced according to the test requirements, saving operation time. In addition, in this application, the cylindrical magnet slides in the chute of the base slide rail, realizing the position adjustment of the test board and the radiator in the first direction; by changing the fixed position of the base slide rail, the position adjustment of the test board and the radiator in the second direction is realized; by replacing cylindrical magnets of different heights, the position adjustment of the test board and the radiator in the third direction is realized. Therefore, this application can flexibly adjust the test position of the radiator according to the test requirements, meet the test conditions under different conditions, and improve the test efficiency.
