Description

Technical Field

[0001] The utility model belongs to the technical field of pipe joints, and in particular relates to a transition joint for testing the sealing performance of a liquid cooling plate. Background Art

[0002] Liquid cooling plate, also known as water cooling plate, is a device used for heat dissipation. It usually includes cooling module, cooling coil, connecting plate, pump, water tank and other parts. The heat of the heating device is indirectly transferred to the cooling liquid enclosed in the circulation pipeline through the cold plate (generally a closed cavity made of heat-conducting metals such as copper and aluminum), and the heat is then taken away by the cooling liquid.

[0003] In order to ensure that the liquid cooling plate does not leak cooling liquid during normal operation, the circulation pipeline needs to be tested for sealing before leaving the factory. The ends of the circulation pipelines of different models of liquid cooling plates (the ends in this application refer to the connecting holes opened on the plane) have different forms, such as through holes or threaded holes, and the hole diameters are different. This results in the need to prepare a variety of connectors to match the ends of the above-mentioned circulation pipelines during the sealing test, such as plugs inserted into through holes, or threaded connectors that need to be screwed into threaded holes, etc., which will increase the number and types of test tools for sealing tests, which is not convenient for management and cost control.

[0004] In addition, the plug generally requires a corresponding tensioning mechanism, which is complex in structure and easy to damage; the threaded joint needs to be used with sealing materials (such as raw tape), and the loading and unloading time is relatively long. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a liquid cooling plate sealing test transition joint, which is used to solve the technical problem that the existing joints are inconvenient to connect with the liquid cooling plate, and different specifications of liquid cooling plates require different joints.

[0006] The utility model solves the above technical problems with the following technical solutions: a liquid cooling plate sealing test transition joint, comprising:

[0007] A connecting block, wherein the connecting block is provided with a plurality of vertical through holes, the upper part of the through holes is provided with internal threads, the internal threads are used to connect the pipe joints, the bottom surface of the connecting block is provided with a plurality of annular sealing grooves, and the plurality of sealing grooves are sleeved outside the plurality of through holes in a one-to-one correspondence, and the sealing grooves are used to accommodate sealing rings;

[0008] The top surface of the connecting block is also provided with at least two parallel waist-shaped holes;

[0009] A limit block is arranged on the bottom surface of the connecting block, and the limit block slides along the waist-shaped hole.

[0010] The utility model aligns the through hole of the connecting block with the end of the liquid cooling plate so that the through hole covers the end, and then clamps the connecting block and the liquid cooling plate with a clamp, wherein the sealing ring realizes sealing, and adjusts the position of the limit block so that the position from the through hole to the limit block is consistent with the distance from the end to the edge of the liquid cooling plate, and the position is positioned by the limit block; in this way, the test connector mentioned in the present application can adapt to the sealed connection of the ends of different specifications of the liquid cooling plate, and is easy to install.

[0011] Furthermore: the limit block is a vertical block.

[0012] The beneficial effect of adopting this step is that the vertical block and the connecting block are used in conjunction with each other to play the function of auxiliary positioning.

[0013] Further: the limit block is an L-shaped block, the limit block and the connecting block form a U-shaped structure, and the liquid cooling plate is inserted into the U-shaped structure;

[0014] The limit block is also provided with a locking mechanism, and the locking mechanism is used to fix the liquid cooling plate and the connecting block.

[0015] The beneficial effect of adopting this step is that the limit block can not only position, but also fix the liquid cooling plate and the connecting block through the locking mechanism.

[0016] Furthermore: the top surface of the limit block is provided with two threaded columns corresponding to the positions of the waist-shaped holes, the threaded columns extend into the waist-shaped holes, and the top surface of the connecting block is also provided with at least two nuts, and the two nuts are respectively screwed with the threaded columns.

[0017] Furthermore: an internal threaded hole is provided on the top surface of the limiting block at a position corresponding to the waist-shaped hole, and the internal threaded hole is adapted to a bolt inserted into the waist-shaped hole.

[0018] The beneficial effect of adopting this step: the two limit blocks and the connecting block realize the position adjustment mechanism.

[0019] Furthermore: the locking mechanism is a locking bolt arranged on the limit block.

[0020] The beneficial effect of adopting this step is: the locking function is achieved by rotating the locking bolt.

[0021] Furthermore: a groove is provided on the top surface of the connecting plate, and the groove is adapted to the clamp.

[0022] The beneficial effect of adopting this step is that the groove is used to limit the sliding of the clamp on the surface of the connecting block to avoid failure of the clamp.

[0023] The beneficial effects of the utility model are:

[0024] By adjusting the position of the limit block, the distance from the through hole to the limit block is made consistent with the distance from the end to the liquid cooling plate. When the diameter of the through hole is larger than the diameter of the end, the through hole is connected to the end, and the sealing is achieved by using a sealing ring placed in the sealing groove. The connecting block is quickly connected to the liquid cooling plate through a clamp, so that when the liquid cooling plate is tested for sealing, the sealing test equipment can be connected to the liquid cooling plate through the sealing joint. The sealing joint of the present application can be used for ends of various diameters (as long as they are not larger than the through hole), with fast loading and unloading and good sealing effect.

[0045] A connecting block 1, wherein the connecting block 1 is provided with a plurality of vertical through holes 11, and the plurality of through holes 11 can provide a wider range of choices for the connector when in use. For example, if the number of the ends of the liquid cooling plate 3 is more than one, adjacent or spaced through holes 11 can be used. An internal thread is provided on the upper portion of the through hole 11, and the internal thread is used to connect a pipe joint, and the pipe joint can be fixedly connected to the pipeline of the test equipment for a long time. A plurality of annular sealing grooves 13 are provided on the bottom surface of the connecting block 1, and the plurality of sealing grooves 13 are sleeved outside the plurality of through holes 11 in a one-to-one correspondence, and the sealing grooves are used to accommodate sealing rings. When the connecting block 1 is attached to the liquid cooling plate 3 and subjected to pressure (pressure is generally achieved by a clamp, and the clamp generally includes a locking pliers, a clamp, a clamp, etc., and a locking pliers is preferably used in actual use, and the locking pliers can be locked and is easy to operate), sealing can be achieved;

[0046] The top surface of the connecting block 1 is also provided with at least two parallel waist-shaped holes 12;

[0047] The limiting block 2 is arranged on the bottom surface of the connecting block 1 , and the limiting block 2 slides along the waist-shaped hole 12 .

[0048] The utility model aligns the through hole 11 of the connecting block 1 with the end of the liquid cooling plate 3 so that the through hole 11 covers the end, and then clamps the connecting block 1 and the liquid cooling plate 3 with a clamp, wherein the sealing ring realizes sealing, and adjusts the position of the limit block 2 so that the position from the through hole 11 to the limit block 2 is consistent with the distance from the end to the edge of the liquid cooling plate 3, and the position is positioned by the limit block 2; wherein, the diameter of the through hole 11 can be much larger than the diameter of the end, as long as the through hole 11 can cover the end, the test connector mentioned in the present application can adapt to the sealed connection of the ends of different specifications of the liquid cooling plate, and is easy to disassemble and assemble.

[0049] like Figure 1 to Figure 5 , Figure 7 As shown, the limit block 2 is a vertical block.

[0050] The vertical block is used as a backrest and cooperates with the connecting block to assist in positioning.

[0051] like Figure 6 As shown, the limit block 2 is an L-shaped block, the limit block 2 and the connecting block 1 form a U-shaped structure, and the liquid cooling plate 3 is inserted into the U-shaped structure;

[0052] The limiting block 2 is also provided with a locking mechanism, and the locking mechanism is used to fix the liquid cooling plate 3 and the connecting block 1 .

[0053] The limiting block 2 can not only be used for positioning, but also can be used to fix the liquid cooling plate 3 and the connecting block 1 through a locking mechanism.

[0054] On the basis of the above technical solution, there are also the following two embodiments:

[0055] 1) The top surface of the limit block 2 is provided with two threaded columns 21 corresponding to the position of the waist-shaped hole 12, and the threaded columns 21 extend into the waist-shaped hole 12, and the top surface of the connecting block 1 is also provided with at least two nuts, and the two nuts are screwed with the threaded columns 21 respectively.

[0058] On the basis of the above technical solution, the locking mechanism is a locking bolt 22 provided on the limit block 2 .

[0059] The locking bolt 22 is connected to the limit block 2 by threads, and the locking function is achieved by rotating the locking bolt 22. This structure is the most cost-effective and reliable locking method.

[0060] On the basis of the above technical solution, a groove is provided on the top surface of the connecting plate 1, and the groove is adapted to the clamp.

[0061] The purpose of the groove is to limit the sliding of the clamp on the surface of the connecting block 1 to avoid failure of the clamp. For example, the groove can accommodate the jaws of the locking pliers so that the jaws cannot be displaced, thereby preventing the locking pliers from shifting sideways or tilting when impacted by external forces, thereby ensuring the connection effect.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
