[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-2 The present invention provides an embodiment of a modular heat dissipation testing platform, including a test workbench 1, a support plate 4 fixedly connected to the top of the test workbench 1, and a fixing mechanism 5 provided on the top of the test workbench 1; the support plate 4 is L-shaped, and the fixtures for different test items can be quickly installed through the setting of the fixing mechanism 5.

[0034] Reference Figures 3-5The fixing mechanism 5 includes a guide plate 506 fixedly connected to the top of the test workbench 1. A movable plate 504 is slidably connected to the outer wall of the guide plate 506. A protective seat 505 is inserted into the top of the movable plate 504. The guide plate 506 is L-shaped and can guide the movable plate 504, allowing it to move only horizontally. Various types of clamps can be installed on the inner side of the protective seat 505. A rotating column 509 is rotatably connected to the inner wall of the top of the test workbench 1. A gear 510 is fixedly connected to the top of the rotating column 509. The rotation of the gear 510 drives the rotating column 509 to rotate synchronously. A connecting plate 507 is fixedly connected to the outer arc surface on the left side of the rotating column 509. The connecting plate 507 is formed by hinged two sets of vertical plates, and its overall angle can change. A drive assembly 501 is provided at the top of the support plate 505. A clamping plate 502 is provided on the outer wall of the drive assembly 501. There are two sets of clamping plates 502. The drive assembly 501 can drive the two sets of clamping plates 502 to move closer or open synchronously to fix the corresponding clamps. A rack 508 is fixedly connected to the rear end of the right clamping plate 502. The two move along the same trajectory. A fixing block 503 is fixedly connected to the rear end of the guide plate 506. The fixing block 503 can position the protective seat 505 and prevent it from moving backward. A connecting block 511 is slidably connected to the inner wall of the front part of the rack 508. The connecting block 511 can support the rack 508. A dustproof assembly 6 is provided at the bottom front side of the support plate 4. The dustproof assembly 6 can protect the fixing mechanism 5.

[0035] Reference Figures 2-4 The drive assembly 501 includes a fixed plate 5013 fixedly connected to the top of the test workbench 1. The fixed plate 5013 is provided in two sets. A motor 5011 is fixedly connected to the top left side of the test workbench 1. A bidirectional threaded rod 5014 is rotatably connected to the inner wall of the fixed plate 5013. The output end of the motor 5011 is fixedly connected to the left end of the bidirectional threaded rod 5014. The rotation of the output end of the motor 5011 drives the bidirectional threaded rod 5014 to move closer to the center or spread out to both sides. The front end of the connecting block 511 is fixedly connected to the rear part of the guide rod 5012. The two are fixed together to support the connecting block 511. The side of the clamping plate 502 near the center contacts the outer wall of the protective seat 505. The two contacts each other to clamp and fix the protective seat 505.

[0036] Reference Figures 2-4The bottom end of the fixed block 503 is fixedly connected to the top of the test workbench 1. The rear ends of the moving plate 504 and the protective seat 505 are in contact with the front end of the fixed block 503. The test workbench 1 provides support for the fixed block 503. The rear external teeth of the rack 508 mesh with the external teeth of the gear 510. The horizontal movement of the rack 508 drives the gear 510 to rotate. The side of the connecting plate 507 away from the rotating column 509 is hinged to the rear end of the moving plate 504. The hinged design avoids motion interference. When the rotating column 509... When driven to rotate backward by gear 510, the distance between the front and rear of connecting plate 507 becomes shorter, thereby pulling moving plate 504 to move backward. There are two sets of fixed plates 5013, and the two sets of fixed plates 5013 are connected by guide rod 5012. The inner wall of clamping plate 502 is slidably connected to the outer wall of bidirectional threaded rod 5014, and the inner wall of clamping plate 502 is slidably connected to the outer arc surface of guide rod 5012. The rotation of bidirectional threaded rod 5014 promotes the movement of clamping plate 502, and the guide rod 5012 prevents clamping plate 502 from rotating when it moves.

[0037] Reference Figure 1 and Figure 6 The dustproof component 6 includes an electric telescopic rod 602 fixedly connected to the bottom front side of the support plate 4. A horizontal plate 603 is fixedly connected to the movable end of the electric telescopic rod 602. The movable end of the electric telescopic rod 602 drives the horizontal plate 603 to move vertically. A dust cover 601 is fixedly connected to the bottom front side of the support plate 4. The bottom right side of the dust cover 601 is fixedly connected to the left end of the horizontal plate 603. The dust cover 601 can be folded, and by moving the horizontal plate 603 downwards, the dust cover 601 can be pulled open, thereby providing dust protection for the fixing mechanism 5. The left and right sides of the test workbench 1 are also fixedly connected to... The aluminum alloy frame 2 has a fan 3 rotatably connected to its top. A stepper motor is installed at the bottom of the fan 3, which allows for angle adjustment. The aluminum alloy frame 2 has a built-in temperature sensor (patent type, infrared dual mode) to collect the surface temperature of the heat sink in real time, and integrates a thermoelectric cooling chip (TEC) on the contact surface of the bracket to achieve active cooling. The bottom of the dust cover 601 has a square groove, the size of which is larger than the overall length of the fixing mechanism 5 and the overall length of the motor 5011 and the rightmost fixing plate 5013, so as to protect the fixing mechanism 5 from dust when it is not in use.

[0038] Working principle: When different test specimens need to be installed, the motor 5011 is turned on, and its output end drives the bidirectional threaded rod 5014 to rotate. Since the inner wall of the clamping plate 502 is slidably connected to the outer wall of the bidirectional threaded rod 5014 and the outer arc surface of the guide rod 5012, the rotation of the bidirectional threaded rod 5014 will cause the two sets of clamping plates 502 to move closer or open synchronously along the guide rod 5012. When the clamping plates 502 move closer, the corresponding fixture can be clamped and fixed on the protective seat 505. Because the side of the clamping plate 502 near the center is in contact with the outer wall of the protective seat 505, during the movement of the right clamping plate 502, the rack 508 fixedly connected to it moves synchronously. Since the rear external teeth of the rack 508 mesh with the external teeth of the gear 510, the horizontal movement of the rack 508 will drive the gear 510 to rotate. When the gear 510 rotates, it will drive the rotating column 509 fixedly connected to it to rotate synchronously. The connecting plate 507, which is fixed to the outer arc surface on the left side of the rotating column 509, will also move accordingly. The side of the connecting plate 507 away from the rotating column 509 is hinged to the rear end of the moving plate 504. When the rotating column 509 is driven to rotate backward by the gear 510, the distance between the front and back of the connecting plate 507 becomes shorter, thereby pulling the moving plate 504 to move horizontally backward along the guide plate 506. The guide plate 506 guides the moving plate 504, allowing it to move only horizontally. The fixing block 503 can position the protective seat 505 to prevent it from moving backward, and the connecting block 511 supports the rack 508. At this time, the two sets of clamping plates 502 can clamp and fix the protective seat 505, thereby achieving the purpose of quick installation and switching. When the clamping plate 502 moves outward, the protective seat 505 moves forward to the front side of the test workbench 1, making it convenient for the staff to move upward and disassemble the protective seat 505.

[0039] When the fixing mechanism 5 is not in use, the electric telescopic rod 602 is activated, and its movable end drives the horizontal plate 603 to move vertically downward. Since the bottom right side of the dust cover 601 is fixedly connected to the left end of the horizontal plate 603, and the dust cover 601 can be folded as a whole, the downward movement of the horizontal plate 603 will pull the dust cover 601 open. The square groove at the bottom of the dust cover 601 is larger than the overall length of the fixing mechanism 5, the motor 5011, and the rightmost fixing plate 5013, thus providing dust protection for the fixing mechanism 5. Fans 3 are rotatably connected to the aluminum alloy frames 2 on both sides of the test workbench 1. The stepper motor at the bottom of the fan 3 can adjust its angle to meet different heat dissipation test requirements. The aluminum alloy frame 2 has a built-in temperature sensor (patent type, infrared dual mode) that can collect the surface temperature of the heat sink in real time. At the same time, a thermoelectric cooling element (TEC) is integrated on the contact surface of the bracket to achieve active cooling, working in conjunction with the fan 3 to complete the heat dissipation test.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
