Manufacturing Method of Isothermal Vapor Chamber And Product Thereof

Abstract

A manufacturing method of a isothermal vapor chamber and a product thereof are to use an integrated manner to form an orifice directly on a plate body of a isothermal vapor chamber. Through the orifice, the operations of injecting working fluid and degassing or vacuating can be proceeded. The orifice is functionally similar to a degassing tube or a vacuating tube of the prior arts. However, since the orifice is integrated on the plate body of the isothermal vapor chamber body, it can be pressed to seal the isothermal vapor chamber after an operation of degassing. Therefore, the vacuity in the isothermal vapor chamber and the stored amount of the working fluid, and it is easier for manufacture.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention generally relates to a cooling technique, in particular, to a heat pipe.[0003]2. Description of Prior Art[0004]An isothermal vapor chamber is a kind of heat pipes formed as a flat plate, which has a similar working principle as a common heat pipe. Namely, through an internal environment of vacuum, a working fluid contained therein can generate a phase change from liquid to vapor for transferring heat from a heated end to a cooling end. The working fluid condenses into liquid phase at the cooling end, flows back to the heated end and repeats the cycle.[0005]However, an isothermal vapor chamber is different from a heat pipe in terms of manufacture process. The tube body of a heat pipe is usually formed as a tube configuration, one end of which can be sealed first, then another side of which can be processed with the operations of injecting working fluid and degassing. Immediately after the degassing ...

AI Technical Summary

Benefits of technology

[0007]The invention is mainly to provide a manufacturing method of an isothermal vapor chamber and a product thereof. According to the invention, an integrating manner is applied to form an orifice directly on a plate body of an isothermal vapor chamber for being able to process the operations of an injection of working fluid, a de-aeration, and an evacuation. The orifice is functionally similar to a degassing tube or a vacuating tube in the prior arts but, since the orifice is integrated on the plate body of the isothermal vapor chamber, as soon as aforementioned operations have been processed, an immediate pressing and sealing operation can be subsequently processed, so it is possible to accurately control the vacuity in the isothermal vapor chamber and the stored amount of the working fluid. Furthermore, its manufacturing method is much easier.

Problems solved by technology

However, an isothermal vapor chamber is different from a heat pipe in terms of manufacture process.

Under such circumstance, the vacuity in the isothermal vapor chamber and the stored amount of the working fluid will be influenced and out of accurate control.

In the meantime, the manufacturing process is more difficult.
