Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat pipe radiators, in particular to a tin paste coating device for holes of a heat pipe radiator. BACKGROUND

[0002] In modern electronic devices, heat dissipation management is a key factor to ensure device performance and reliability. With the continuous increase in power consumption of electronic devices, heat pipe radiators are widely used in various electronic devices due to their excellent heat conduction performance and high heat dissipation capacity.

[0003] Currently, the installation process of heat pipes mainly includes opening a heat pipe groove on the surface of the heat pipe radiator, pressing the heat pipe into the heat pipe groove and making it in close contact with the surface of the substrate. In order to ensure good thermal contact between the heat pipe and the radiator, tin paste is usually coated between the heat pipe groove and the heat pipe. After the tin paste is heated to melt in the reflow soldering furnace, a firm soldered connection can be formed between the heat pipe and the radiator. After completion, the tin paste is cooled and solidified, thereby realizing the fixation of the heat pipe and the radiator.

[0004] Although the current heat pipe installation process has achieved certain results, there are still some technical bottlenecks and problems. First, when injecting tin paste into the heat pipe groove, due to the influence of the operating environment and process parameters, the distribution of the tin paste is often not uniform, which may lead to insufficient tin paste in some areas, affecting the thermal contact effect of the heat pipe. Secondly, during the process of pressing the heat pipe into the heat pipe groove, the tin paste is prone to overflow, which not only leads to waste of tin paste, but also may contaminate other components, affecting overall production efficiency and product quality.
