Description

technical field [0001] The invention relates to the technical field of heat pipe radiators, in particular to a water-cooled heat pipe radiator and a manufacturing method thereof. Background technique [0002] For the electronic equipment in the server, especially the electronic equipment with high heat flux density, it will generate a lot of heat during operation. In the prior art, these electronic equipment are generally cooled by air cooling. However, the common air-cooling method generally requires additional power consumption to control the ambient temperature, and the fans used in the air-cooling method all have the disadvantage of high noise. Because water has a larger specific heat capacity than air, water-cooled systems have the advantages of quietness, good heat dissipation performance, and less dependence on the environment compared to air-cooled systems. The water cooling system in existing servers generally adopts a built-in water cooling method, that is, the co...

Problems solved by technology

However, the water-cooled heat pipe in the prior art has the disadvantages of unstable structure, low reliability, and inconvenient installation and disassembly.

[0004] The existing water-cooled plate flow channel processing technology mainly adopts CNC machine tools (CNC), deep hole processing, coil welding, cutting process plus CNC, etc., which has the disadvantages of complicated process and high processing cost; in addition, the existing water-cooled plate connection The process mainly adopts brazing process, and part of it adopts fusion welding. Due to the requirements of welding deformation and surface assembly, there must be a certain processing allowance on the surface after welding.

If you want to achieve good sealing performance after processing and have a certain compressive strength at the same time, it is difficult to use traditional welding or brazing, and it is prone to welding defects such as brazing filler metal blocking the water channel or brazing filler metal loss and weak connection

However, contacting the heat pipe with the base and the water-cooled plate by extrusion may easily cause the heat pipe to dent, damage or even fail, resulting in an increase in contact thermal resistance and affecting the heat dissipation effect
