Description

Technical Field

[0001] This utility model relates to the field of heat pipe processing technology, specifically a heat pipe powder uniform feeding device. Background Technology

[0002] A heat pipe is a highly efficient heat transfer element that rapidly transfers heat using the principle of phase change heat absorption and release, with a thermal conductivity far exceeding that of any known metal. A heat pipe consists of three main components: a sealed outer shell, a working fluid, and a capillary structure. The outer shell maintains a vacuum seal for the working fluid, which changes phase within the application temperature range and must be compatible with the materials of the outer shell and capillary structure.

[0003] The processing of heat pipes is complex and precise. One of the processes is heat pipe powder filling, which involves inserting a stainless steel core rod into the center of a copper tube and positioning it in the exact middle of the tube using a mold. Then, copper powder of a specified particle size is filled in (the copper powder is made to reach a certain density using a vibration device to control the porosity of the capillary structure after sintering). Conventional heat pipe powder filling uniform feeding devices have some limitations in practical applications. On the one hand, the feeding uniformity of some conventional devices is difficult to control precisely. During the powder filling process, due to the lack of an effective and precise control mechanism, the powder filling amount is prone to instability. This leads to inconsistent copper powder density at different locations inside the heat pipe, which in turn affects the porosity of the capillary structure after heat pipe sintering and reduces the heat transfer performance of the heat pipe. At the same time, the device has poor scalability. Utility Model Content

[0013] This utility model provides a heat pipe powder uniform feeding device, which has the following beneficial effects: 1. This utility model, through the structural design of the expansion seat component, the combined use of the expansion tube component and the matching side cover, wherein the first expansion combination seat and the assembly flange are connected and combined through a standard flange structure, allows the expansion tube component to be stably installed on the expansion seat component, while facilitating disassembly and replacement, improving the flexibility and maintainability of the equipment. Furthermore, the embedded docking installation between the second expansion combination seat on the expansion seat component and the support tube component further enhances the structural stability of the entire device, ensuring that it will not loosen or fall off during feeding. Additionally, due to the upper and lower sides of the main seat body and the front and rear sides... Each side surface is equipped with a first expansion assembly seat, which allows the expansion assembly to flexibly connect multiple expansion tube components according to actual needs, thereby adapting to the powder filling operation of heat pipes of different specifications and quantities.

The mating flange 402 and the connecting flange 302 are mated together, and the assembly flange 502 and the first expansion assembly seat 102 are also mated together. The use of standard flange connections allows for a secure and convenient connection between the mating flange 402 and the connecting flange 302, and between the assembly flange 502 and the first expansion assembly seat 102.

Simultaneously, the standard flange design facilitates standardized production and mass manufacturing of the equipment, reducing production costs, and makes subsequent upgrades and modifications more convenient, enabling rapid adaptation to components of different specifications and models.

[0020] like Figures 1 to 4 As shown, the feeding assembly 2 includes a shock absorber 201, a direct drive motor 202, and a feeding screw 203. The direct drive motor 202 is horizontally mounted in the middle of the side of the shock absorber 201 away from the extension base component 1, and the feeding screw 203 is horizontally mounted on the power output end of the direct drive motor 202 via a coupling. The support pipe component 3 includes a main pipe body 301, a connecting flange 302, and a bearing bracket 303. The connecting flange 302 is integrally provided at both ends of the main pipe body 301, and the bearing bracket 303 is provided at the end of the main pipe body 301 away from the extension base component 1.

[0022] In summary, as Figures 1 to 4As shown, when using this heat pipe powder uniform feeding device, firstly, according to the actual production needs, the expansion tube component 5 is connected and combined with the first expansion combination seat 102 on the expansion seat component 1 through the assembly flange 502, and the quantity and position of the expansion tube component 5 are determined. If multiple expansion tube components 5 need to be connected, they can be flexibly connected by the first expansion combination seat 102 set on the upper and lower sides and the front and rear sides of the main body 101, so as to realize the conveying and mixing of various powders. Next, the support pipe component 3 is embedded and installed with the second expansion combination seat 103 on the expansion seat component 1 through the connecting flange 302 to ensure a stable connection and enhance the structural stability of the entire device. Then, the connecting flanges 402 at both ends of the first hose 401 of the connecting pipe component 4 are firmly connected to the connecting flange 302 of the support pipe component 3 and other related components to ensure the sealing of the connection and prevent powder leakage. At the same time, the protective coating 403 on the outer surface of the first hose 401 can resist the corrosion of the external environment and extend the service life of the hose. Then, the feeding assembly 2 is started, the direct drive motor 202 runs, and the shock absorber 201 effectively reduces the vibration generated by the direct drive motor 202 during operation. The direct drive motor 202 directly drives the feeding screw 203 to rotate. The feeding screw 203 is horizontally mounted in the middle of the main body 101 and the main body 301, and the end away from the direct drive motor 202 is horizontally installed through the shaft of the bearing bracket 303, providing a stable support point for the feeding screw 203, reducing the bending and deformation of the screw during operation, making the feeding screw 203 evenly stressed during operation, reducing wear, and accurately controlling the feeding speed and feeding amount, so that the powder is conveyed to the designated position through the rotation of the feeding screw 203. Throughout the feeding process, the antistatic coating 7 applied to the inner surfaces of the extension seat component 1, support pipe component 3, connecting pipe component 4, extension pipe component 5, and side cover 6, as well as the output end surface of the feeding assembly 2, effectively prevents powder from adsorbing onto the inner wall of the equipment or generating electrostatic sparks during conveying. This avoids dust adsorption and blockage caused by static electricity, ensuring the safety and stability of the device operation, improving the quality and production efficiency of the heat pipe filling process. If the device needs to be inspected or cleaned, the side cover 6 can be quickly disassembled due to its standard flange structure connection with the first extension assembly seat 102. The connecting pipe component 4 and extension pipe component 5 can also be quickly disassembled and replaced according to their connection method, improving the efficiency of equipment maintenance.
