Description

TECHNICAL FIELD

[0001] The utility model relates to the field of heat pipe powder filling, in particular to a heat pipe powder filling deviation prevention device. BACKGROUND

[0002] The heat pipe powder filling deviation prevention device is a device for ensuring uniform distribution of powder (such as wick material) inside a heat pipe and preventing powder deviation.

[0003] The heat pipe powder filling deviation prevention device with the publication number CN221439513U belongs to the field of heat pipe powder filling processing, and is used to solve the problem that in the process of filling the heat pipe, the filling material falls into the copper pipe through the powder cup, and the guiding effect of the filling material is not ideal, resulting in uneven falling of the filling material. The uniformity of the filling material inside the heat pipe, as a kind of efficient heat transfer element, plays a crucial role in heat conduction performance. The heat pipe usually has a metal pipe body such as a copper pipe as a shell, and is internally filled with powder with specific functions. During the feeding process, many challenges are faced. The powder itself has certain physical properties, and the tension of the powder is a key factor. Due to the interaction force between the powder particles, this tension has a significant impact when the powder enters the inside of the copper pipe. When the powder is transported to the copper pipe inlet and starts to fill, under the action of tension, the powder does not flow into the internal space of the copper pipe in an ideal loose and uniform state. The powder particles may agglomerate or form a local compact structure, which hinders their settlement and spreading process in the copper pipe. As the filling process proceeds, these powder lumps gathered or compacted due to tension and the copper pipe inner wall and the subsequent filled powder are difficult to achieve close adhesion, thus gaps are easily formed inside the copper pipe. The existence of these gaps directly leads to uneven filling. Uneven filling can cause a series of serious problems. The heat conduction efficiency of the heat pipe is greatly reduced. Because the heat conduction path is interrupted or hindered when heat passes through the area filled with gaps, an effective continuous heat conduction channel cannot be formed, and the ability of the heat pipe to quickly transfer heat from the evaporation end to the condensation end is reduced. SUMMARY

[0004] The purpose of the utility model is to provide a heat pipe powder filling deviation prevention device.
