Description

Technical Field

[0001] The utility model belongs to the technical field of inspection tools, and in particular relates to a liquid cooling plate inspection tool. Background Art

[0002] A liquid cold plate is a form of temperature control that uses a cold plate (usually a closed cavity made of heat-conducting metals such as copper and aluminum) to indirectly transfer the heat of a heating device to a cooling liquid enclosed in a circulating pipe, and then removes the heat through the cooling liquid.

[0003] Liquid cold plates are widely used in servers, electronic equipment, LED lighting, solar inverters and other fields, especially in high-density server heat dissipation and LED lamp heat control.

[0004] With the advancement of technology in the above fields, the production and assembly accuracy of related equipment have been further improved. In order for the liquid cooling plate to meet the assembly requirements, the size of the liquid cooling plate must be accurately detected. However, in existing liquid cooling plates, the heat pipes are basically serpentine pipes, and the heat pipes are also connected to the base plate, resulting in a complex shape and difficult to quickly detect. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a liquid cooling plate inspection tool for solving the technical problem that the prior art cannot quickly inspect the liquid cooling plate.

[0006] The technical solution of the present invention to solve the above technical problems is as follows: a liquid cooling plate inspection fixture, comprising:

[0007] Workbench;

[0008] A limit block, wherein the top surface of the limit block is provided with a cavity adapted to the liquid cooling plate;

[0009] a pair of transverse slide rails, the pair of transverse slide rails being respectively arranged on both sides of the limit block;

[0010] A longitudinal slide rail, each of which is connected to a pair of transverse slide rails via two movable slides;

[0011] A detection slide, the detection slide is arranged on the longitudinal slide rail, and the detection slide is provided with a measuring tool;

[0012] Two positioning platforms are provided on the other side relative to the longitudinal slide rail, and are used to position the inlet and outlet of the liquid cooling plate.

[0013] The utility model can quickly check the shape and position dimensions of the liquid cooling plate through the cavity of the limit block. Only the liquid cooling plate that meets the shape and position dimensions can be placed in the cavity. Then, the measuring tool on the detection slide is used to further test the liquid cooling plate, including flatness, surface roughness, etc. Finally, the positioning table is used to test the inlet and outlet of the liquid cooling plate. If all three pass, it is a qualified liquid cooling plate. The utility model can detect liquid cooling plates more quickly.

[0014] Furthermore: the limit block includes several limit modules, the limit modules include a head end module, a tail end module and a middle module, and the limit blocks are arranged in sequence according to the head end module, the middle module and the tail end module.

[0015] The beneficial effect of this step is that the size of the middle part of the liquid cooling plate is relatively the same and will not change, while the head and tail ends have larger changes. Therefore, part of the middle module can be omitted, which can achieve the purpose of reducing the cost and weight of the inspection fixture.

[0016] Furthermore: the measuring tool is a caliper, a dial indicator, a micrometer or a laser length measuring instrument.

[0017] The beneficial effect of this step is that different measuring tools can be used for targeted testing according to the accuracy requirements of the liquid cooling plate and the needs of the test items.

[0018] Furthermore: the positioning platform includes:

[0019] Column;

[0020] A connecting rod, one end of which is hinged to the top surface of the column, and the other end of which is provided with a vertical measuring column, the diameter of the test end of the measuring column being adapted to the inlet and outlet apertures of the liquid cooling plate.

[0021] The beneficial effect of adopting this step is: using the test end of the measuring column to detect the inner hole diameter of the inlet and outlet of the liquid cooling plate.

[0022] Furthermore: a positioning ring is further provided on the measuring column, and the height of the positioning ring is the standard height of the inlet and outlet of the liquid cooling plate;

[0023] The side of the column is provided with a limiting pin, which is used to keep the connecting rod horizontal;

[0024] The top surface of the column is further provided with a limiting plate, and the limiting plate is arranged on both sides of the connecting rod. A positioning hole is opened on the limiting plate and the connecting rod, and the positioning hole is equipped with a positioning pin.

[0025] The beneficial effect of this step is that the connecting rod remains horizontal, and only a feeler gauge or caliper is needed to detect the gap between the locating ring and the liquid cooling plate inlet and outlet, thereby determining the height of the liquid cooling plate inlet and outlet.

[0026] Furthermore: a baffle is also provided at the rear end of the limiting plate.

[0027] The beneficial effect of this step is that the baffle prevents the connecting rod from turning outward too much, causing the measuring column to exceed the range of the inspection fixture itself, which is prone to scratches and affects the accuracy of the measuring column.

[0028] The beneficial effects of the utility model are:

[0029] 1. This utility model uses the cavity of the limit block to detect the shape and position of the liquid cooling plate, and then uses an omnidirectional movable measuring tool to detect the overall flatness of the liquid cooling plate. The positioning platform also detects the position, inner diameter and height of the liquid cooling plate inlet and outlet;

[0030] 2. This inspection tool can detect the parameters of liquid cooling plate comprehensively and at a fast speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Example

[0047] like Figures 1 to 4 As shown, the present invention provides a liquid cooling plate inspection fixture, comprising:

[0048] Workbench 1;

[0049] A limit block 2, wherein the top surface of the limit block 2 is provided with a cavity adapted to the liquid cooling plate 7, and the shape, position and size of the cavity match the liquid cooling plate 7;

[0050] a pair of transverse slide rails 3, wherein the pair of transverse slide rails 3 are respectively arranged on both sides of the limit block 2;

[0051] A longitudinal slide rail 4, wherein the longitudinal slide rail 4 is connected to a pair of transverse slide rails 3 via two movable slides;

[0052] A detection slide 41 , the detection slide 41 being arranged on the longitudinal slide rail 4 , and the detection slide 41 being provided with a measuring tool 5 ;

[0053] Two positioning platforms 6 are provided on the other side relative to the longitudinal slide rail 4 , and the positioning platforms 6 are used to position the inlet and outlet of the liquid cooling plate 7 .

[0054] The present invention can quickly check the shape and position dimensions of the liquid cooling plate through the cavity of the limit block 2. Only the liquid cooling plate that meets the shape and position dimensions can be placed in the cavity. Otherwise, interference will occur and the liquid cooling plate 7 cannot be placed in the cavity. Then, the measuring tool 5 on the detection slide 41 is used to further test the liquid cooling plate 7, including flatness, surface roughness, etc. Finally, the positioning table 6 is used to test the inlet and outlet of the liquid cooling plate 7. If all three pass, it is a qualified liquid cooling plate. The present invention is faster in testing liquid cooling plates.

[0055] Based on the above technical solution, the limit block 2 includes several limit modules, and the limit modules include a head end module 21, a tail end module 23 and an intermediate module 22. The limit blocks are arranged in the order of the head end module 21, the intermediate module 22 and the tail end module 23.

[0056] Relatively speaking, the size of the middle part of the liquid cooling plate 7 is the same and does not change, while the head end and the tail end have larger changes. Therefore, part of the middle module 22 can be omitted, which can achieve the purpose of reducing the cost and weight of the gauge.

[0057] On the basis of the above technical solution, the measuring tool 5 is a caliper, a dial indicator, a micrometer or a laser length measuring instrument.

[0058] According to the accuracy requirements of the liquid cooling plate 7 and the needs of the test items, different measuring tools can be selected for targeted testing to obtain parameters such as flatness and surface roughness.

[0059] On the basis of the above technical solution, the positioning platform 6 includes:

[0060] Column 61;

[0061] A connecting rod 62 , one end of which is hinged to the top surface of the column 61 , and a vertical measuring column 63 is provided at the other end of the connecting rod 62 , the diameter of the testing end of the measuring column 63 being adapted to the inlet and outlet apertures of the liquid cooling plate 7 .

[0062] The inner hole diameter of the inlet and outlet of the liquid cooling plate 7 is detected by using the test end of the measuring column 63 .

[0063] On the basis of the above technical solution, a positioning ring 631 is further provided on the measuring column 63, and the height of the positioning ring 631 is the standard height of the inlet and outlet of the liquid cooling plate 7;

[0064] A limiting pin 612 is provided on the side of the column 61, and the limiting pin 612 is used to keep the connecting rod 62 in a horizontal state;

[0065] A limit plate 611 is further provided on the top surface of the column 61 . The limit plates 611 are provided on both sides of the connecting rod 62 . A positioning hole is provided on each of the limit plates 611 and the connecting rod 62 . The positioning hole is provided with a positioning pin 64 .

[0066] When connecting rod 62 remains horizontal, a feeler gauge or caliper is used to measure the clearance between locating ring 631 and the inlet and outlet of liquid cooling plate 7, thereby determining the height of the inlet and outlet of liquid cooling plate 7. Furthermore, locating pin 64 ensures that connecting rod 62 remains horizontal over a long period of time, improving detection accuracy.

[0067] On the basis of the above technical solution, a baffle 613 is further provided at the rear end of the limiting plate 611 .

[0068] The baffle 613 is used to prevent the connecting rod 62 from turning outward too much, causing the measuring column 63 to exceed the range of the inspection tool itself, which may easily cause scratches and affect the accuracy of the measuring column 63.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
