Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate technology, specifically a multi-channel microfluidic liquid cooling plate for heat dissipation and cooling. Background Technology

[0002] With the rapid development of electronic equipment, new energy batteries and other fields, the heat generated during equipment operation has increased dramatically. Efficient heat dissipation technology has become the key to ensuring stable operation and extending service life of equipment. Traditional air cooling methods are limited by ambient temperature and heat dissipation efficiency, and are difficult to meet heat dissipation requirements in high-power heat dissipation scenarios. Although ordinary liquid cooling plates can achieve a certain heat dissipation effect, they have the problem of cumbersome installation and disassembly.

[0003] Traditional liquid cooling plates are mostly fixed with bolts. During installation, each bolt needs to be tightened one by one, which is not only time-consuming and labor-intensive, but also makes it difficult to guarantee positioning accuracy, affecting assembly efficiency. Disassembly is also complicated, which is not conducive to equipment maintenance and repair, and requires a lot of disassembly and assembly time, affecting the downtime of the equipment.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a multi-channel microfluidic liquid cooling plate for heat dissipation and cooling, comprising: an installation structure 1, a cover structure 2 slidably connected to the outer wall of the installation structure 1; the installation structure 1 includes a base plate 11, a first cooling groove 12 is formed on the inner wall of the base plate 11, a sealing gasket 13 is fixedly connected to the outer wall of the base plate 11, a positioning pin 14 is fixedly connected to the outer wall of the base plate 11, flow joints 15 are symmetrically slidably connected to the inner wall of the base plate 11, a slide rod 16 is symmetrically fixedly connected to the outer wall of the side of the base plate 11, a pull plate 17 is slidably connected to the outer wall of the slide rod 16, a positioning block 18 is fixedly connected to the outer wall of the pull plate 17, and a compression spring 19 is symmetrically fixedly connected to the outer wall of the pull plate 17 on the side away from the positioning block 18.

[0026] The sealing gaskets 13 are symmetrically arranged on both sides of the first cooling tank 12 to seal the first cooling tank 12 and prevent leakage. The positioning pins 14 are arranged in an array along the four corners of the base plate 11.

[0027] The outer wall of the compression spring 19 on the side away from the pull plate 17 is fixedly connected to the outer wall of the slide rod 16. When the pull plate 17 is pulled, it is pulled along the slide rod 16 in a direction away from the cover plate 21, overcoming the elastic force of the compression spring 19, which can drive the positioning block 18 to move. The pull plates 17 are arranged in an array along the four corners of the base plate 11.

[0028] The cover structure 2 includes a cover plate 21. The inner wall of the cover plate 21 is provided with a second cooling groove 22, the outer wall of the cover plate 21 is provided with a sealing groove 23, the outer wall of the cover plate 21 is provided with a positioning hole 24, the outer wall of the side of the cover plate 21 is provided with a positioning groove 25, and a heat dissipation fin 26 is fixedly connected to the inner wall of the side of the cover plate 21 away from the second cooling groove 22.

[0029] Positioning holes 24 and positioning grooves 25 are arranged in an array along the four corners of the cover plate 21, and sealing grooves 23 are symmetrically arranged on both sides of the second cooling groove 22.

[0030] The outer wall of the base plate 11 contacts the outer wall of the cover plate 21, the outer wall of the sealing gasket 13 is slidably connected to the inner wall of the sealing groove 23, the outer wall of the positioning pin 14 is slidably connected to the inner wall of the positioning hole 24, the outer wall of the flow connector 15 is slidably connected to the inner wall of the cover plate 21, and the outer wall of the positioning block 18 is slidably connected to the inner wall of the positioning groove 25. The positioning pins 14 at the four corners of the base plate 11 are inserted into the positioning holes 24 of the cover plate 21 to achieve the alignment of the installation structure 1 and the cover structure 2.

[0031] In use, the multi-channel microfluidic liquid cooling plate structure is realized by the cooperation of the mounting structure 1 and the cover structure 2, and by the locking of the positioning block 18 and the positioning groove 25.

[0032] During installation, the positioning pins 14 at the four corners of the base plate 11 are inserted into the positioning holes 24 of the cover plate 21 to align the installation structure 1 with the cover structure 2. The pull plate 17 slides along the slide rod 16, causing the positioning block 18 to be embedded into the positioning groove 25 of the cover plate 21. At the same time, the compression spring 19 provides elastic pressure, so that the base plate 11 and the cover plate 21 fit tightly together. The sealing gasket 13 on the base plate 11 slides and engages with the sealing groove 23 of the cover plate 21 to form a double sealing structure.

[0033] The coolant enters through the inlet of the flow joint 15 on the base plate 11 and flows through the closed flow channel formed by the combination of the first cooling tank 12 and the second cooling tank 22. The tank structures of the first cooling tank 12 and the second cooling tank 22 cooperate with each other to form an S-shaped microchannel array, which increases the contact area between the fluid and the substrate and enhances convective heat transfer. After the coolant absorbs the heat from the heat source attached to the base plate 11, it is discharged from the outlet of the other flow joint 15 to complete the heat dissipation cycle. The heat dissipation fins 26 on the inner wall of the cover plate 21 can increase the heat exchange area in the flow channel and improve the heat exchange efficiency between the fluid and the wall.

[0034] When disassembly is required, pull the pull plate 17 and pull it away from the cover plate 21 along the slide rod 16 to overcome the elastic force of the compression spring 19. When the pull plate 17 moves to the end of the slide rod 16, the positioning block 18 completely disengages from the positioning groove 25 of the cover plate 21, and the bottom plate 11 can be separated from the cover plate 21 to complete the disassembly, which facilitates operations such as cleaning the flow channel and replacing parts.
