Problems solved by technology

In the production process of this kind of flat heat pipe, whether the connection between the finer mesh and the thicker mesh metal copper mesh is accurate will affect the heat conduction between the metal copper mesh, and then affect the heat dissipation effect of the flat heat pipe
[0011] In addition, the use of general diffusion bonding is also easily affected by the flatness of the pressure-applying jig.
If the flatness of the jig is not good, it is easy to cause poor lamination between the components at the press joint of the jig, resulting in insufficient strength and tightness after diffusion bond

Abstract

The ultrasonic welding process for making plate heat pipe includes the following steps: 1. ultrasonically welding capillary structure to one of the upper plate and the lower plate and superposing these two plates with the capillary structure in between; and 2. sealing the plates with the capillary structure inside. The ultrasonically welded plate heat pipe has high bond strength, high tightness, lowered heat resistance and high heat dissipating effect, and shortened production process.

Description

technical field [0001] The invention relates to a method for manufacturing a flat heat pipe, in particular to a method for manufacturing a flat heat pipe using ultrasonic welding. Background technique [0002] Since the integration density of integrated circuit components such as a central processing unit (CPU) continues to increase, the heat generation density thereof also continues to increase. If the heat cannot be effectively dissipated, the working performance of the components will be affected. [0003] Under the trend that portable electronic devices are becoming thinner, thinner and smaller, the problem of heat dissipation is becoming more and more serious, and general heat dissipation devices are gradually facing the bottleneck that it is difficult to improve the heat dissipation effect. [0004] Therefore, the emergence of flat heat pipes can be used as a good heat dissipation device for portable electronic devices in due course. [0005] The operating principle o...
