Vapor chamber with separator

Abstract

A vapor chamber with separator includes shell, capillary tissue, separator, supporting structure and working fluid. The shell includes inter-sealed lower and upper shell plates. Partial section of the lower shell plate projects downwardly and forms accommodating room therein. The capillary tissue is arranged by distributing over inner wall of the lower shell plate. The separator overlapped the capillary tissue is arranged penetrating trough corresponding to the accommodating room. Liquid passage is formed between the lower shell plate and the separator. The supporting structure is accommodated in the shell with upper and lower sides respectively inter-abutted against the upper shell plate and the separator. Vapor passage formed between the upper shell plate and the separator is communicated to the liquid passage. The working fluid is filled into the shell. Since the vapor and liquid working fluids are separated by the separator to avoid interference, the cooling performance is thus boosted.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention in general relates to a vapor chamber, in particular, to a vapor chamber with separator.[0003]2. Description of Prior Art[0004]The quicker computing speed of a computer is, relatively the more waste heat of computing element (for example, CPU) in computer generates. How to remove the waste heat from the interior of computer chassis in time to make computing element operated under normal temperature has become an issue intended to be addressed urgently by each manufacturer.[0005]In order to enhance the cooling performance of computer chassis, the use of vapor chamber can boost the cooling efficiency significantly. As a general rule, a prior vapor chamber includes an upper shell plate, a lower shell plate, a capillary tissue, a supporting structure and a working fluid. The upper shell plate and the lower shell plate are inter-sealed to each other, between which an accommodating space is formed. The c...

AI Technical Summary

Benefits of technology

[0009]The invention is mainly to provide a vapor chamber with separator, in which the separator separates the working fluid in vapor phase from the working fluid in liquid phase in a way, such that they won't be interfered to each other and the cooling performance is boosted.

[0011]Compared with prior arts, the invention has following merits. Since the separator separates the working fluid in vapor phase from the working fluid in liquid phase, the working fluid of each phase has its own passage to avoid interfering to each other, reaching the function of boosting cooling performance significantly. In addition, by arranging folded pieces on the separator, it can further prevent the working fluid in vapor phase from flowing in reverse direction into the liquid passage to generate any interference with the working fluid in liquid phase.

Problems solved by technology

However, the prior vapor chamber structure still has some drawbacks in terms of practical usage.

Since the phase change between vapor and liquid occurs in a same accommodating space, it will substantially happen an interference between the working fluid in vapor phase flowing upwardly and the working fluid in liquid phase flowing downwardly, whereby an entire cooling performance of the vapor chamber is lowered down.
