Example Embodiment

[0031] Example 1: Reference figure 1 , figure 2 , This liquid-cooled cylindrical heat pipe radiator includes a cylindrical heat pipe 1, a guide vane 2, an outer tube 3, a sleeve cover 4, a connector 5, and a fastener 6. A guide vane 2 is sleeved or welded on the outer wall surface of the tube body 1-2 of the cylindrical heat pipe 1. The guide vane 2 is used to increase the flow rate and disturbance of the liquid and strengthen heat transfer. At the same time, the guide vane 2 and the cylindrical heat pipe The tube body 1-2 of 1 is in close contact to form a heat dissipation surface; an outer tube 3 is provided on the outer side of the baffle 2, and the inner wall surface of the outer tube 3 and the outer wall surface of the cylindrical heat pipe 1 and the baffle 2 form a connected liquid channel 7; The upper end of the outer sleeve 2 is provided with a sleeve cover 4, and the outer sleeve 3 is provided with liquid connection pipes 5 respectively connected to the two ends of the ...

Example Embodiment

[0035] Example 2: Reference image 3 , The difference from Embodiment 1 is that the liquid nozzle 5 is set on the sleeve cover 4 of the liquid-cooled cylindrical heat pipe radiator, which can be easily installed or replaced according to the use occasion and the fastening method. 6.

Example Embodiment

[0036]Example 3: Reference Figure 6 The difference from Embodiments 1 and 2 is that one or more spiral guide vanes 2 are welded or sleeved on the outer wall of the cylindrical heat pipe 1 or directly opened on the outer wall surface of the cylindrical heat pipe 1 tube body 1-2, Cooperating with the inner wall surface of the outer tube 3 and the outer wall surface of the cylindrical heat pipe 1 to form a spiral liquid channel 7, the liquid nozzle 5 can be arranged on the side of the outer tube 3 or on the sleeve cover 4. The guide vane 2 not only increases the heat dissipation area, but also increases the liquid flow rate and turbulence, strengthens the heat absorption of the cooling liquid, reduces the thermal resistance, and has a better heat dissipation effect.

Abstract

A liquid-cooling type column shape heat-pipe radiator comprises column-shape heat pipe, diversion sheet on the external wall of the heat pipe, external casing pipe fitted on the outer side of the diversion sheet. The inner wall of the external casing pipe, the outer wall of the heat pipe and the diversion sheet form a liquid passage. On the external casing pipe or the casing pipe cover is fitted with a liquid connection tube communicated respectively to the two ends of the liquid passage. The lower end face of the casing pipe is provided together with the base plate of the column-shape heat pipe. Advantages: largely reduced thermal resistance and raised heat-conducting ability, small volume, light weight and compact structure.

Description

technical field [0001] The invention relates to a cooling device, in particular to a liquid-cooled cylindrical heat pipe radiator used in high-power electronic components such as computer CPUs, communications, photoelectric lighting, and IGBTs. Background technique [0002] With the development and miniaturization of electronic products such as computers, communications, and photoelectric lighting LEDs at an astonishing rate in the "Moore's Law" equivalent series, the relative heat treatment problems are also increasing, and the heat flux is also increasing. How to solve this heat dissipation problem in a limited space and ensure the normal operation of electronic products requires that cooling module manufacturers and related scientific research institutions around the world increase investment in scientific research, actively seek and develop new types of high-efficiency heat dissipation that can meet the development needs of next-generation electronic products components....
