Description

Technical Field

[0001] The invention relates to the field of liquid cooling and heat dissipation, and in particular to a forming method of a liquid cooling chassis embedded with a copper tube. Background Art

[0002] As the power of electronic equipment continues to grow, air cooling can no longer meet the cooling needs of the equipment, and liquid cooling has become a trend. Liquid cooling chassis, as an important part of liquid cooling, has been widely used. Traditional liquid cooling chassis have internal flow channels formed by milling aluminum cold plates. The chemicals in the coolant will react with the aluminum, causing corrosion of the cold plate and blockage of the flow channel, which cannot be repaired. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that the internal flow channel of a liquid cooling case is blocked and cannot be repaired due to corrosion of an aluminum refrigeration plate, and a liquid cooling case with an embedded copper tube is proposed.

[0004] The technical solution to achieve the purpose of the present invention is: a liquid-cooled chassis, which adopts the form of three-sided liquid flow, including an upper plate, a lower plate, a left plate, a right plate, upper and lower plate copper tubes, a first side plate copper tube, a second side plate copper tube, an upper and lower cover plate, a first side cover plate and a second side cover plate, wherein: The upper plate, the lower plate, the left plate and the right plate are welded to form a chassis frame, and flow channel grooves are processed on the surfaces of the upper plate, the lower plate and the right plate. Upper and lower plate copper tubes are arranged in the flow channel grooves of the upper plate and the lower plate, and the upper and lower cover plates are pressed on the surfaces of the upper and lower plate copper tubes and fixed to the upper plate and the lower plate by screws. The first side plate copper tube and the second side plate copper tube are arranged in the flow channel groove of the right plate, and the first side cover plate and the second side cover plate are pressed on the right plate and fixed to the right plate by screws. The first side plate copper tube and the upper and lower plate copper tubes are connected by screws and sealed by O-rings, and the second side plate copper tube and the upper and lower plate copper tubes are connected by screws and sealed by O-rings. The coolant enters from the inlet of the second side plate copper tube, flows through the upper and lower plate copper tubes of the upper plate, the first side plate copper tube, the upper and lower plate copper tubes of the lower plate, and flows out from the outlet of the second side plate copper tube.

[0005] Furthermore, the upper plate, the lower plate, the left plate and the right plate are made of 6063 aluminum plate.

[0006] Furthermore, the upper and lower plate copper tubes, the first side plate copper tubes and the second side plate copper tubes are formed by bending red copper tubes.

[0007] Furthermore, the copper tubes of the upper and lower plates are oval tubes with dimensions of 9.7mm x 5mm and a circumference of 25.13mm. The bending radius of the copper tube is 15mm, and the spacing between the copper tubes in the loop is 43mm.

[0008] Furthermore, the first side plate copper tube and the second side plate copper tube are round tubes with an inner diameter of 8 mm and a circumference of 25.13 mm.

[0009] Furthermore, copper blocks are welded to both ends of the upper and lower plate copper tubes, the first side plate copper tube, and the second side plate copper tube, and are nickel-plated.

[0010] Furthermore, the upper and lower plate copper tubes, the first side plate copper tubes, and the second side plate copper tubes are required to remain watertight for 30 minutes under a pressure of 1.6 MPa.

[0011] Furthermore, thermal conductive silicone grease is applied to the flow channel grooves of the upper plate and the lower plate.

[0012] A forming method of a liquid cooling chassis, the specific process is as follows: The upper plate, the lower plate, the left plate and the right plate are welded to form a chassis frame; Place the copper tubes of the upper and lower plates into the grooves of the flow channels of the upper and lower plates; press the upper and lower covers onto the surfaces of the copper tubes of the upper and lower plates, and connect the upper and lower covers with the upper and lower plates using screws; Place the first side plate copper tube and the second side plate copper tube into the flow channel groove of the right side plate, install four O-rings into the flange grooves of the first side plate copper tube and the second side plate copper tube respectively, and use screws to connect the first side plate copper tube and the second side plate copper tube with the upper and lower plate copper tubes; use screws to connect the first side cover plate and the second side cover plate with the right side plate.

[0013] Compared with the prior art, the present invention has the following significant advantages: the heat is dissipated from the modules inside the chassis by means of three-sided liquid flow, and the flow channels are all inside the chassis, without the need for external pipes; the copper tube is used as a carrier of the coolant, which solves the problem of corrosion and blockage of the aluminum plate in the coolant; and screws are used to connect the cover plate and the frame, so that even if the copper tube is damaged, it can be replaced, thereby improving maintainability.
