Description

Technical Field

[0001] This utility model relates to a liquid cooling box plate, and more particularly to a liquid cooling channel capable of adjusting the flow rate. 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 of precision instruments. However, heat dissipation has always been a research challenge for miniaturized and compact precision instruments. This is because heat sinks are usually installed inside precision instruments, and the heat sinks themselves require a large space, which increases the size of the precision instruments. The solution is generally to make the outer casing of the precision instrument a hollow structure, and to use the coolant inside the hollow outer casing to cool the precision instruments inside the casing. The design of liquid cooling channels has obvious advantages. Traditional liquid cooling plates only have a single liquid cooling channel that runs from end to end. The cross-sectional area of ​​this liquid cooling channel is fixed and cannot be adjusted according to the cooling requirements, so it cannot adjust the cooling range inside the casing, which has certain limitations. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model discloses a liquid cooling channel capable of adjusting the flow rate. By setting a partition strip in the liquid cooling tank, a liquid cooling channel A with a larger flow area and a liquid cooling channel B with a smaller flow area are formed after the cover strip covers the liquid cooling tank. The through hole set on one side of the center of the connecting straight circular tube is connected to the liquid cooling channel A or the liquid cooling channel B after rotation, so as to achieve the purpose of forming a larger or smaller flow area of ​​coolant by rotating the connecting straight circular tube as needed.

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

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. A partition strip is provided inside the liquid cooling tank. The partition strip is a combination of multiple straight partition strips and multiple curved partition strips connected end-to-end to form multiple "U"-shaped structures. The partition strip divides the liquid cooling tank into a wider tank A and a narrower tank B. The top of the partition strip is close to the opening of the tank. The cover strip is placed inside the liquid cooling tank, and tank A and tank B are covered by the cover strip. The cover forms a liquid cooling channel A with a larger flow area and a liquid cooling channel B with a smaller flow area. Inlet and outlet blind holes are provided on the side wall of the plate near both ends of the liquid cooling tank. A through hole A is provided between the two inlet and outlet blind holes and both ends of liquid cooling channel A, and a through hole B is provided between the two inlet and outlet blind holes and both ends of liquid cooling channel B. Through holes A and B are located on opposite sides of the bottom axis of the inlet and outlet blind holes.

[0021] Combined with appendix Figures 1-5The adjustable flow rate liquid cooling channel includes a cover strip 1, a flat plate 5, and a connecting straight circular tube 16. The cover strip 1 is a combination of multiple straight cover strips 3 and multiple arc-shaped cover strips 2 connected end to end to form multiple "U"-shaped structures. A liquid cooling tank 8 is provided on the top surface of the flat plate 5. The liquid cooling tank 8 is a combination of multiple straight grooves 10 and multiple arc-shaped grooves 9 connected end to end to form multiple "U"-shaped structures. A partition strip 4 is provided inside the liquid cooling tank 8. The partition strip 4 is a combination of multiple straight partition strips 6 and multiple arc-shaped partition strips 7 connected end to end to form multiple "U"-shaped structures. The partition strip 4 divides the liquid cooling tank 8 into... A wider tank A18 and a narrower tank B19 are formed. The top of the partition strip 4 is close to the tank opening. The cover strip 1 is placed inside the liquid cooling tank 8. After being covered by the cover strip 1, tanks A18 and B19 form a liquid cooling channel A20 with a larger flow area and a liquid cooling channel B21 with a smaller flow area. The bottom surface of the cover strip 1 inside the liquid cooling tank 8 is in contact with the top surface of the partition strip 4. The opposite side walls of the cover strip 1 are in contact with the side walls of the liquid cooling tank 8. The top of the cover strip 1 is flush with the tank opening of the liquid cooling tank 8. Inlet and outlet are provided on the side wall of the flat plate 5 near both ends of the liquid cooling tank 8. A liquid blind hole 13 has a through hole A11 between each end of the two inlet / outlet liquid blind holes 13 and the liquid cooling channel A20, and a through hole B12 between each end of the two inlet / outlet liquid blind holes 13 and the liquid cooling channel B21. Through holes A11 and B12 are located on opposite sides of the bottom axis of the inlet / outlet liquid blind holes 13. A through hole 22 is provided inside the connecting straight circular tube 16, located between the side wall and the axis of the connecting straight circular tube 16 and extending through both ends. One end of each of the two connecting straight circular tubes 16 is rotatably connected to the two inlet / outlet liquid blind holes 13, and the ends of each of the two connecting straight circular tubes 16 are respectively connected to the two inlet / outlet liquid blind holes 13. The bottoms of holes 13 are in contact with each other. Sealing sleeves 14 are fitted on the two connecting straight round tubes 16 located inside the liquid inlet / outlet blind hole 13. Two handles 15 are respectively provided on the two connecting straight round tubes 16 located outside the liquid inlet / outlet blind hole 13.

The cover strip 1 and the plate 5 are both made of aluminum.

[0022] To implement the liquid cooling channel with adjustable flow rate described in this utility model, the cover strip 1 is placed inside the liquid cooling tank 8 and subjected to diffusion welding in a vacuum diffusion welding furnace. This results in tanks A18 and B19 forming a wider liquid cooling channel A20 and a narrower liquid cooling channel B21 after being covered by the cover strip 1. In use, one end of each of the two connecting straight round tubes 16 is inserted into the two inlet / outlet blind holes 13, ensuring that the ends of each connecting straight round tube 16 contact the bottom of the two inlet / outlet blind holes 13. The two connecting straight round tubes 16 are then rotated as needed to connect the through holes 22 and... With perforations A11 and B12 aligned coaxially, the other ends of the two connecting hoses 17 are connected to the inlet and outlet ports of the radiator, respectively. The liquid cooling channels A20 and B21 are filled with coolant, and the coolant is circulated using the radiator. As needed, the two handles 15 can be turned to switch from the wider liquid cooling channel A20 to the narrower liquid cooling channel B21, or vice versa. This allows for the rotation of the connecting straight circular tube 16 to create a larger or smaller flow area as needed.
