However, the body of the vapor chamber is plate-shaped, and usually consists of two cover plates that are covered by the upper and lower phases. It is not only necessary to seal the edges of the two cover plates, but also to reserve an injection port for the aforementioned Injection of working fluid, degassing and other vacuum operations; in the past, in the manufacture of vapor chambers, a degassing pipe or a vacuum tube must be inserted on the injection port to facilitate the injection of working fluid, degassing and other vacuum operations. And when the above-mentioned operations are completed, the degassing pipe or vacuum pipe must be removed before the injection port can be closed, which will affect the vacuum degree inside the vapor chamber and the sealing volume of the working fluid, and cannot be precisely controlled. At the same time, it is more troublesome to manufacture

Embodiment Construction
[0035] In order to enable those skilled in the art to further understand the characteristics and technical content of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. However, the accompanying drawings are provided for reference and illustration only, and are not intended to limit the present invention. .
[0036] see figure 1 , is a flowchart of the steps of the method of the present invention. The invention provides a vapor chamber and a manufacturing method thereof, the steps of which are as follows:
[0037] First, if figure 2 As shown, the two cover plates 10, 11 required to form the plate body 1 of the chamber are prepared, and the two cover plates 10, 11 can be covered together to form the plate body 1, and in the plate body 1 A hollow accommodating space 12 (as shown in FIG. 6 ) that can be closed by the two cover plates 10 and 11 is formed. The two cover plates 10, 11 are made of materia...

The invention provides a temperature-uniforming plate and manufacturing method thereof; an opening part, which is like a known degassing tube or vacuum-pumping tube and for injecting working fluid, degassing and the like is directly formed on the temperature-uniforming plate in an integrated manner, and can be pressed and sealed immediately after finishing degassing operation and the like when integrated on the temperature-uniforming plate, so that the vacuum degree and sealing quantity of the working fluid in the temperature-uniforming plate can be controlled accurately and the manufacturingis easy.
Description
technical field [0001] The invention relates to a heat dissipation technology, in particular to a uniform temperature plate and a manufacturing method thereof. Background technique [0002] Vapor chamber is a kind of plate-shaped heat pipe. Its principle is the same as that of heat pipe. It passes through the internal vacuum environment to provide the working fluid injected into it. It can change its phase due to heat, and then transfer heat; In liquid state, it can be circulated after reflux. [0003] However, vapor chambers are manufactured differently than heat pipes. The tube body of the heat pipe is usually in the shape of a tube. One end of the tube body can be closed first, and then the vacuum operation such as injecting working fluid and degassing can be performed through the other open end. When the degassing is completed, the tube body should be closed immediately. Finished making the heat pipe. However, the body of the vapor chamber is plate-shaped, and usually...
