Description

Technical Field

[0001] This utility model relates to a liquid-cooled box plate, and more particularly to a box plate liquid-cooled channel with a snap-fit ​​structure. Background Technology

[0002] With the advancement of science and technology and the continuous development of various precision instruments, miniaturization and compactness are the development trends. However, heat dissipation has always been a research challenge for miniaturized and compact precision instruments. This is because heat sinks are usually installed inside the precision instrument, and the heat sinks themselves occupy a large space, thus increasing the size of the precision instrument. The solution is generally to make the outer casing of the precision instrument a hollow structure, and to use coolant placed inside the hollow outer casing to cool the precision instrument inside the casing. The design of liquid cooling channels has obvious advantages, but the disadvantages are also undeniable. The sealing problem of liquid cooling channels has always been a difficult point in this innovative technology. If the liquid cooling channel leaks, the coolant will flow into the chassis and damage the electronic components inside the chassis. When existing liquid cooling boxes are diffusion-bonded and encapsulated in liquid cooling channels, clamps are generally used to clamp the liquid cooling cover plate and the liquid cooling box plate together. When the liquid cooling box plate is heated, the clamps will block and absorb some heat, which can easily cause uneven heating of the liquid cooling box plate. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model discloses a box-plate liquid cooling channel with a snap-fit ​​structure. By setting inclined surfaces on the opposite side walls of the liquid cooling tank, and setting snap-fit ​​grooves at the lower ends of the side walls of multiple straight grooves, and setting inclined sides with inwardly tapering lower ends on the opposite sides of the cover strips, and setting protruding strips at the lower ends of the two inclined sides of the multiple straight cover strips, the cover strips are pressed into the liquid cooling tank using a press, so that the inclined surfaces and inclined sides fit together, and the protruding strips are placed in the snap-fit ​​grooves. Then, diffusion welding is used to seal the two together, eliminating the cumbersome process of clamping the two together with a fixture in the traditional sealing process.

[0004] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0005] A liquid cooling channel with a snap-fit ​​structure includes a cover strip and a flat plate. The cover strip is a combination of multiple straight cover strips and multiple curved cover strips connected end to end to form multiple "U"-shaped structures. A through groove is provided at the bottom of the cover strip. On both sides of the cover strip, there are inclined edges that taper inward at the lower end, so that the cross-section of the cover strip forms an inverted trapezoidal structure. There are raised strips at the lower ends of the two inclined edges of the multiple straight cover strips. A liquid cooling tank is provided on the top surface of the flat plate. The liquid cooling tank is a combination of multiple straight grooves and multiple curved grooves connected end to end to form multiple "U"-shaped structures. The two side walls of the liquid cooling tank are set as inclined surfaces with the groove opening width greater than the groove bottom width, so that the cross-section of the liquid cooling tank forms an inverted trapezoidal structure. There are snap-fit ​​grooves at the lower ends of the two side walls of the multiple straight grooves. The cover strip is placed in the liquid cooling tank, with the inclined edges and inclined surfaces fitting together. The multiple raised strips are located in the multiple snap-fit ​​grooves. The through groove is covered by the bottom of the liquid cooling tank at the opening to form a liquid cooling channel.

[0006] The liquid cooling channel with snap-fit ​​structure has inlet and outlet holes at both ends of the liquid cooling tank and between the side walls of the plate.

[0007] The liquid cooling channel with snap-fit ​​structure has an interference fit between the beveled side and the beveled surface.

[0008] The liquid cooling channel with snap-fit ​​structure has a matching cover strip and a liquid cooling tank.

[0009] The liquid cooling channel with snap-fit ​​structure described above has aluminum as the material for both the cover strip and the flat plate.

[0010] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0011] The liquid cooling channel with a snap-fit ​​structure described in this utility model features a liquid cooling tank on the chassis wall, inclined surfaces on opposite side walls of the liquid cooling tank, snap-fit ​​grooves at the lower ends of the side walls of multiple straight grooves, a through groove at the bottom of the cover strip, inclined sides that taper inward on opposite sides of the cover strip, and raised strips at the lower ends of the inclined sides of the multiple straight cover strips. The cover strip is pressed into the liquid cooling tank using a press, ensuring the inclined surfaces and inclined sides fit together, and the raised strips are placed in the snap-fit ​​grooves. Then, diffusion welding is used to seal both, eliminating the cumbersome process of using clamps to hold them together for diffusion welding in traditional sealing methods. This utility model utilizes a traditional snap-fit ​​structure to join the cover strip after it is installed in the liquid cooling tank but before diffusion welding, achieving the effect of increasing the tightness between the cover strip and the liquid cooling tank without the need for clamps.

[0016] The present invention can be explained in more detail through the following embodiments. The present invention is not limited to the following embodiments. The purpose of disclosing the present invention is to protect all changes and improvements within the scope of the present invention.

[0017] Combined with appendix Figures 1-3 The aforementioned liquid cooling channel with a snap-fit ​​structure includes a cover strip 8 and a flat plate 2. The cover strip 8 is a combination of multiple straight cover strips 7 and multiple arc-shaped cover strips 6 connected end to end to form multiple "U"-shaped structures. A through groove 11 is provided at the bottom of the cover strip 8, and inclined sides 10 that taper inward at their lower ends are provided on opposite sides of the cover strip 8, so that the cross-section of the cover strip 8 forms an inverted trapezoidal structure. A protruding strip 9 is provided at the lower end of the two inclined sides of the multiple straight cover strips 7. A liquid cooling tank 3 is provided on the top surface of the flat plate 2. The liquid cooling tank 3 is a combination of multiple straight grooves 4 and multiple arc-shaped grooves 5 connected end to end to form multiple "U"-shaped structures. Both sides of the liquid cooling tank 3 are designed with inclined surfaces 12, the width of the groove opening being greater than the width of the bottom of the groove, so that the cross-section of the liquid cooling tank 3 forms an inverted trapezoidal structure. There are slots 13 at the lower ends of the two sides of the multiple straight grooves 4. The cover strip 8 is placed inside the liquid cooling tank 3. The cover strip 8 and the liquid cooling tank 3 are a matching structure. The inclined side 10 and the inclined surface 12 are fitted together. The inclined side 10 and the inclined surface 12 are an interference fit. Multiple protruding strips 9 are located in multiple slots 13. The through groove 11 forms a liquid cooling channel 14 after the opening is covered by the bottom of the liquid cooling tank 3. There are liquid inlet and outlet holes 1 at both ends of the liquid cooling tank 3 and between the side walls of the plate. The cover strip 8 and the plate 2 are both made of aluminum.

[0018] In implementing the liquid cooling channel with snap-fit ​​structure described in this utility model, when using it, the cover strip 8 is pressed into the liquid cooling tank 3 using a press. When the cover strip 8 is installed into the liquid cooling tank 3, the two sides of the through groove 11 on the straight cover strip 7 with protruding strips 9 are slightly elastically deformed by the pressure of the liquid cooling tank 3. The elastic deformation is completely restored only after the cover strip 8 is fully installed and the protruding strips 9 are snapped into the slots 13. At this time, the interference fit of the inclined edge 10 and the inclined surface 12 is close together, and multiple protruding strips 9 are located in multiple slots 13. After the through groove 11 is covered by the bottom of the liquid cooling tank 3 at the opening, it forms a liquid cooling channel 14. Then, the flat plate 2 covered with the cover strip 8 is placed in a vacuum diffusion welding furnace for diffusion welding. After the welding is completed, the two inlet and outlet holes 1 are connected to the inlet and outlet ports of the radiator respectively. The liquid cooling channel 14 is filled with coolant, and the coolant is circulated by the radiator, so as to achieve the purpose of stable operation of the liquid cooling channel 14 without leakage.

[0019] The parts of this utility model not described in detail are existing technologies.
