Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a heat dissipation module power testing fixture. Background Technology

[0002] As the performance of electronic devices gradually improves, the power consumption and heat generation of electronic components increase. Therefore, different types of heat dissipation products are usually used to dissipate heat from electronic devices.

[0003] Cooling products come in various types. For example, a common type of cooling module, the CPU cooler, has a heat pipe structure. When testing the cooling power of this type of cooling module, it needs to be fixed on a corresponding fixture. The measured cooling power is the cooling power of the module placed at a fixed angle on the fixture. However, in actual use, due to installation or environmental factors, the angle of the cooling module may not be exactly the same as during testing, and the cooling power will change. For example, for a cooling module with a heat pipe structure, the working fluid inside the heat pipe is affected by gravity due to the angle change, thus affecting its cooling power.

[0004] Therefore, in the prior art, the heat dissipation power measured after fixing the heat dissipation module with a fixture differs from the heat dissipation power when the heat dissipation module is actually used, thus reducing the reference significance of the test results.

[0064] See Figures 1 to 6 This embodiment provides a power testing fixture for a heat dissipation module, including a support frame 10, two support blocks 20, a support ring 30, a locking mechanism 40, and a testing mechanism 50.

[0065] Two support blocks 20 are rotatably mounted on the support frame 10. The two support blocks 20 share a rotation center line and are symmetrically arranged. An arc-shaped groove 21 with open ends is formed on the opposite side of each support block 20. A support ring 30 is located between the two support blocks 20. The two ends of the support ring 30 slide within the arc-shaped grooves 21, limiting its movement. The support ring 30 can only slide within these grooves to achieve its rotation. A locking mechanism 40 is used to lock the support ring 30. A testing mechanism 50 is located inside the support ring 30 and is used to fix and test the heat dissipation power of the heat dissipation module. The axis of the support ring 30 is perpendicular to the rotation center line of the two support blocks 20.

[0066] In this embodiment, the heat dissipation module (e.g., CPU heat sink) is fixed on the test mechanism 50. By rotating two support blocks 20 on the support frame 10 and sliding the support ring 30 in the arc groove 21 of the two support blocks 20, the heat dissipation module on the test mechanism 50 can change angle to fit the actual use scenario, so that the measured heat dissipation power data is more meaningful.

[0067] In one embodiment, the support frame 10 includes a base 11 and an arc-shaped block 12.

[0068] The arc-shaped block 12 is connected to the base 11, with its opening facing upwards. Coaxial first holes 121 are formed at both ends of the arc-shaped block 12. A first rod 22 is connected to each of the two support blocks 20 on their opposite sides. The first rod 22 is inserted into the corresponding first hole 121. A bearing is fitted around the first rod 22. The outer ring of the bearing is connected to the inner wall of the first hole 121.

[0069] In this embodiment, the support block 20 is rotatably mounted at both ends of the arc-shaped block 12 via the first rod 22. By rotating the support block 20 at the end of the arc-shaped block 12, the support ring 30 can be driven to rotate around the axis of the first rod 22.

[0070] In one embodiment, the outer ring of the support ring 30 is provided with a circumferential protrusion 31; the bottom of the arc groove 21 is provided with a relief groove 23; the relief groove 23 is clearance-fitted with the corresponding protrusion 31; a second hole 201 is provided on one of the support blocks 20; and a coaxial third hole 221 is provided on the first rod 22.

[0071] The locking mechanism 40 includes a limit block 41 and a locking lever 42.

[0072] The limiting block 41 is connected to the outer wall of one end of the arc-shaped block 12. The limiting block 41 has a fourth hole 411 coaxial with the first hole 121 and the second hole 201. One end of the locking rod 42 passes through the fourth hole 411, the third hole 221 and the second hole 201 in sequence and abuts against the corresponding protrusion 31. The locking rod 42 is threaded to the inner wall of the fourth hole 411. The end of the locking rod 42 away from the protrusion 31 can be connected to a butterfly handle to facilitate the rotation of the locking rod 42. The end of the locking rod 42 away from the butterfly handle is connected to a rubber block, which can protrude from the bottom of the relief groove 23 and abut against the protrusion 31 on the support block 20.

[0073] In this embodiment, by rotating the locking rod 42, the end of the locking rod 42 abuts against the protrusion 31 outside the support ring 30, thereby locking the support block 20. The protrusion 31 is small in size, and the rubber block at the end of the locking rod 42 can increase the friction between the two and improve the locking effect.

[0074] In one embodiment, the locking mechanism 40 further includes a locking ring 43, which is sleeved around the locking rod 42 and located outside the limiting block 41. The locking ring 43 is movable and abuts against the limiting block 41. The locking ring 43 is located between the butterfly handle and the first rod 22. The locking ring 43 may be made of rubber, and a protrusion 31 may be provided on the side of the limiting block 41 facing the locking ring 43. When the locking rod 42 rotates forward, the locking ring 43 abuts against the limiting block 41, thereby preventing the locking rod 42 from continuing to rotate, and consequently preventing the entire support ring 30 from continuing to rotate, thus completing the locking process.

[0075] In one embodiment, the testing mechanism 50 includes a support plate 51, a heating block 52, a testing block 53, a plurality of clamping blocks 54, a temperature sensor 55, a PLC controller, and a drive mechanism 56.

[0076] Support plate 51 is connected to support ring 30. Heating block 52 is disposed on support plate 51. Test block 53 is disposed on heating block 52, and test block 53 can transfer heat. Multiple clamping blocks 54 are movably disposed on support plate 51, and clamping blocks 54 are used to press the heat dissipation module against test block 53. Temperature sensor 55 is connected to test block 53. PLC controller is electrically connected to temperature sensor 55, and external display can be connected to PLC controller to display temperature data. Drive mechanism 56 is used to drive clamping blocks 54.

[0077] In this embodiment, the support plate 51 is made of heat-insulating material, and the heating block 52 heats the test block 53 so that the test block 53 maintains a certain temperature. The temperature of the test block 53 can be obtained through the temperature sensor 55, PLC controller and display. Then the heat dissipation module works to reduce the temperature of the test block 53, thereby calculating the heat dissipation power.

[0078] In one embodiment, the support plate 51 has a plurality of fifth holes 511. The drive mechanism 56 includes a cylinder 561, a connecting frame 562, and a plurality of connecting pipes 563.

[0079] Cylinder 561 is connected to the end of support plate 51 opposite to clamping block 54. Connecting bracket 562 is connected to the output end of cylinder 561. One end of connecting pipe 563 is connected to connecting bracket 562, and the other end of connecting pipe 563 slides through the corresponding fifth hole 511 and connects to the corresponding clamping block 54. The clamping block 54 fixes the heat dissipation module by moving connecting pipe 563 driven by cylinder 561.

[0080] In one embodiment, the drive mechanism 56 further includes multiple second rods 564, multiple square rods 565, a baffle 566, and a baffle plate 567.

[0081] The second rod 564 is threadedly connected to the end of the corresponding connecting pipe 563 furthest from the connecting bracket 562. The square rod 565 is connected to the end of the corresponding second rod 564 furthest from the connecting pipe 563 along the center line. The baffle 566 is connected to the end of the square rod 565 furthest from the second rod 564. The spring 567 is sleeved on the outside of the square rod 565. The end of the clamping block 54 has a square hole. The square rod 565 slides into the square hole; the two ends of the spring 567 abut against the clamping block 54 and the baffle 566 respectively.

[0082] In this embodiment, the heat dissipation module is placed on the test block 53, and then the second rod 564 is rotated, causing the clamping block 54 to rotate above the test block 53. The connecting pipe 563 then causes the clamping block 54 to press against the heat dissipation module. The clamping block 54 is rotatable and can move axially along the second rod 564, thus adapting to heat dissipation modules of various shapes (not limited to CPU coolers). Furthermore, the presence of the spring 567 allows for greater movement of the square rod 565 along its centerline, adapting to heat dissipation modules of more sizes. Moreover, the threaded connection between the second rod 564 and the connecting pipe 563 also allows adjustment of the distance between the clamping block 54 and the test block 53, thereby adapting to heat dissipation modules of more sizes.

In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
