Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling boxes, in particular to a liquid cooling box body for multiple modules. Background Art

[0002] A liquid cooling box body refers to a key part in a liquid cooling system, which is used to accommodate cooling liquid and other related components. In traditional liquid cooling boxes, the liquid cooling plate and the substrate are usually welded. Welding liquid cooling boxes usually require a highly precise manufacturing process, including precise welding techniques and equipment, and the process is complex. This not only increases the manufacturing cost but also prolongs the production cycle. Since the liquid cooling box formed by welding is integrally formed, if a certain component needs to be maintained or replaced, the entire liquid cooling box usually needs to be disassembled, which is not only time-consuming and laborious but also may increase the maintenance cost. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a liquid cooling box body for multiple modules, which solves the technical problems of high welding production cost and inconvenient maintenance of traditional liquid cooling boxes.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: A liquid cooling box body for multiple modules includes a substrate, a flow channel plate, and an upper flat plate arranged in sequence from bottom to top. An embedding groove is opened on the outer side of the upper flat plate, and a sealing strip is installed inside the embedding groove. A sealing groove corresponding to the embedding groove is opened on the inner wall of the flow channel plate. A groove is opened on the top of the flow channel plate, and a plugging airbag is installed inside the groove. A plurality of uniformly distributed air inlet holes are opened on the inner wall of the embedding groove, and both the sealing strip and the groove are communicated with the air inlet holes. A pressing piece is arranged on the top of the upper flat plate.

[0005] Further, a support frame is welded inside the substrate, and a first reinforcement frame is fixedly sleeved outside the substrate.

[0006] Further, a second reinforcement frame is fixedly sleeved outside the upper flat plate, and the length and width of the second reinforcement frame are respectively adapted to the length and width of the first reinforcement frame.

[0007] Further, mounting holes for installing pull rivet nuts are opened on the four sides of the pressing piece, the second reinforcement frame, and the first reinforcement frame. The number of the mounting holes is multiple, and the multiple mounting holes are evenly distributed at equal intervals.

[0008] Further, guide blocks are fixedly connected to the four corners of the first reinforcement frame, and the guide blocks are L-shaped.

[0009] Further, the height of the upper flat plate is set to the sum of the thicknesses of the substrate, the flow channel plate, the upper flat plate, and the pressing piece.

[0010] With the above technical solution, the present utility model provides a liquid-cooled box for multi-modules, which has at least the following beneficial effects:

[0011] 1. By splitting the liquid-cooled box into multiple components such as a base plate, a flow channel plate, and an upper flat plate, and assembling them using rivet nuts, compared with the traditional welding method, this solution not only reduces the production cost but also facilitates the subsequent maintenance and replacement of the components of the liquid-cooled box separately. By setting a pressing piece, the splicing seam between the flow channel plate and the upper flat plate can be sealed, and the sealing strip can be extruded to block the airbag, causing the sealing strip to expand and embed into the sealing groove for secondary sealing of the flow channel plate and the upper flat plate, achieving a double-sealing effect, effectively preventing the leakage of the refrigerant, and ensuring the sealing performance of the equipment after assembly while modularizing the equipment.

[0012] 2. By setting a guiding block, it helps the staff to assemble the equipment. Placing the flow channel plate 2 and the upper flat plate along the guiding block on the upper surface of the base plate in sequence can ensure the alignment of multiple mounting holes, facilitating the installation of rivet nuts.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] In traditional liquid cooling boxes, the liquid cooling plate and the base plate are usually welded. Welding liquid cooling boxes usually require a highly precise manufacturing process, including precise welding techniques and equipment, and the process is complex. This not only increases the manufacturing cost but also prolongs the production cycle. Since the liquid cooling box formed by welding is integrally formed, if a certain component needs to be maintained or replaced, the entire liquid cooling box usually needs to be disassembled, which is not only time-consuming and laborious but also may increase the maintenance cost.

[0021] To solve the defects existing in the production process of the above liquid cooling box, please refer to Figures 1-4 , the present utility model provides a liquid cooling box body for multiple modules. The production of this liquid cooling box adopts an assembly method, which disassembles the liquid cooling box into multiple components. This not only reduces the production cost but also facilitates the later maintenance of the liquid cooling box. At the same time, it can ensure the flatness of the surface of the liquid cooling box and the sealing effect on the coolant. This liquid cooling box body is based on a base plate 1, a flow channel plate 2, and an upper flat plate 3 arranged in sequence from bottom to top. The flow channel plate 2 is provided with a diversion groove, and the bottom of the upper flat plate 2 is provided with a sealing edge adapted to the diversion groove. Combining the flow channel plate 2 and the upper flat plate 3 can form a liquid cooling plate. The sealing edge can enclose the diversion groove to form a flow channel for the coolant to flow through. The upper surface of the upper flat plate 3 has good flatness, which can effectively increase the contact area and contact quality between the device and the heat dissipation device, contribute to optimizing the heat transfer and heat dissipation efficiency, enable the liquid cooling plate to cool more effectively, and the base plate 1 can provide support for the flow channel plate 2 to ensure the stability of the device. Disassembling the traditional integrally formed liquid cooling box into three modules of the base plate 1, the flow channel plate 2, and the upper flat plate 3 facilitates the later maintenance or replacement of a certain module.

[0022] Since the flow channel plate 2 and the upper flat plate 3 are of a split design, there will be a gap at the connection between the flow channel plate 2 and the upper flat plate 3, which may cause the refrigerant in the flow channel plate 2 to leak. In order to ensure the tightness after the assembly of the flow channel plate 2 and the upper flat plate 3 while realizing the modularization of the device, an embedding groove 4 is provided on the outer side of the upper flat plate 3, and a sealing strip 5 is installed inside the embedding groove 4. A sealing groove 15 corresponding to the embedding groove 4 is provided on the inner wall of the flow channel plate 2. When the upper flat plate 3 is inserted into the flow channel plate 2, the sealing groove 15 and the embedding groove 4 are aligned. The sealing strip 5 in the embedding groove 4 enters the sealing groove 15 to block the connection between the flow channel plate 2 and the upper flat plate 3, avoiding the leakage of the refrigerant. In order to enable the sealing strip 5 to enter the sealing groove 15, a groove 7 is provided at the top of the flow channel plate 2. The embedding groove 4, the sealing groove 15 and the groove 7 are all set as loop grooves. A plugging airbag 8 is installed inside the groove 7. The upper surface of the plugging airbag 8 protrudes from the upper surface of the upper flat plate 3. A plurality of uniformly distributed air inlet holes 9 are provided on the inner wall of the embedding groove 4. The sealing strip 5 is set as a hollow rubber strip. The sealing strip 5 and the groove 7 are both communicated with the air inlet holes 9. A pressing piece 6 is provided on the top of the upper flat plate 3. On the one hand, the pressing piece 6 is used to perform secondary plugging on the connection between the flow channel plate 2 and the upper flat plate 3, cooperating with the sealing strip 5 to achieve a double sealing effect, which can effectively prevent the refrigerant in the flow channel plate 2 from leaking. On the other hand, when the pressing piece 6 is installed on the upper flat plate 3, it can squeeze the plugging airbag 8 downward. The air in the plugging airbag 8 is squeezed into the sealing strip 5 along the air inlet holes 9, causing the sealing strip 5 to expand. After the sealing strip 5 expands, it enters the sealing groove 15 and fits with the sealing groove 15 to achieve the sealing of the flow channel plate 2. With such a setting, not only can the liquid cooling box be modularized, but also the tightness of the spliced liquid cooling box can be ensured, reducing the production cost, and it is also convenient for the later maintenance and replacement of the components of the liquid cooling box.

[0023] To ensure the overall stability of the device, referring to Figure 1 as shown, a support frame 14 is welded inside the base plate 1, and a first reinforcement frame 10 is fixedly sleeved outside the base plate 1. By welding the planar support frame 14, a more solid and stable structure can be formed inside the base plate 1. The addition of the support frame 14 can disperse the external pressure and force, making the base plate 1 more uniform and stable when bearing the load, thereby improving the overall structural strength.

[0024] Similarly, to ensure the stability of the upper flat plate 3 and facilitate the connection of the base plate 1, the flow channel plate 2 and the upper flat plate 3, a second reinforcement frame 11 is fixedly sleeved outside the upper flat plate 3. The length and width of the second reinforcement frame 11 are respectively adapted to the length and width of the first reinforcement frame 10. The sizes of the first reinforcement frame 10 and the second reinforcement frame 11 are both adapted to the size of the flow channel plate 2. When the base plate 1, the flow channel plate 2 and the upper flat plate 3 are spliced and overlapped, the outer surfaces of the first reinforcement frame 10, the second reinforcement frame 11 and the flow channel plate 2 are flush.

[0025] For the convenience of disassembling and assembling the substrate 1, the flow channel plate 2 and the upper flat plate 3, mounting holes 12 for installing rivet nuts are provided around the pressing piece 6, the second reinforcing frame 11 and the first reinforcing frame 10. The number of the mounting holes 12 is set to be multiple, and the multiple mounting holes 12 are evenly distributed at equal intervals. The substrate 1, the flow channel plate 2 and the upper flat plate 3 can be connected by the rivet nuts to form a liquid cooling box.

[0026] Since it is difficult to quickly align the multiple mounting holes 12 when the substrate 1, the flow channel plate 2 and the upper flat plate 3 overlap, which will affect the subsequent installation of the rivet nuts. To solve this technical problem, guide blocks 13 are fixedly connected to the four corners of the first reinforcing frame 10. The guide blocks 13 are set in an L shape. The flow channel plate 2 and the upper flat plate 3 are sequentially placed on the upper surface of the substrate 1 along the guide blocks 13, which can ensure the alignment of the multiple mounting holes 12. Finally, the pressing piece 6 is placed on the upper flat plate 3, and the pressing piece 6 is fixed on the top of the upper flat plate 3 by the rivet nuts. At this time, the pressing piece 6 can seal the joint of the flow channel plate 2 and the upper flat plate 3. At the same time, the pressing piece 6 can squeeze the sealing airbag 8 to make the sealing strip 5 expand and embed into the sealing groove 15 to seal the flow channel plate 2 and the upper flat plate 3 again, and then the assembly can be completed.

[0027] To ensure the flatness of the upper surface of the device, the height of the upper flat plate 3 is set to the sum of the thicknesses of the substrate 1, the flow channel plate 2, the upper flat plate 3 and the pressing piece 6. After the substrate 1, the flow channel plate 2, the upper flat plate 3 and the pressing piece 6 are assembled, the four corners of the pressing piece 6 are flush with the upper ends of the guide blocks 13, which can optimize the flatness of the device.
