A thermal column with grooved sintered porous layer composite liquid-absorbent core

Abstract

The invention discloses groove sintering type porous layer composite liquid absorbing core heat column. The groove sintering type porous layer composite liquid absorbing core heat column comprises a pipe body and a multi-groove flowing channel, wherein grooves in the multi-groove flowing channel extend from one end of the pipe body to the other end of the pipe body; two elastic separating plates are arranged in an inner empty cavity of the pipe body and divide the inner empty cavity of the pipe body into two side chambers and an intermediate chamber in the width direction; the intermediate chamber is positioned between the two side chambers; a flexible metal inner tank is stored in each of the side chambers and the intermediate chamber; the pipe body comprises a first pipe body and a second pipe body which are oppositely closed to each other; an elastic supporting part which can be contracted into the pipe body is connected between the first pipe body and the second pipe body; and thefirst pipe body and the second pipe body can be stretched to form an opening through the elastic supporting part. The groove sintering type porous layer composite liquid absorbing core heat column hasthe advantages that the capillary pressure is high; the reflowing resistance is small; the opening is conveniently formed, so that elements in the pipe body can be conveniently detected, repaired andreplaced.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a groove sintered porous layer composite liquid-absorbing core thermal column. Background technique [0002] The heat column, also known as the heat pipe, makes full use of the principle of heat conduction and the rapid heat transfer properties of the phase change medium, and quickly transfers the heat of the heating object to the heat source through the heat pipe, and its thermal conductivity exceeds that of known metals. [0003] Existing heat pipes generally include a hollow and airtight metal shell, a capillary structure inside the shell, and a working medium filled in the shell. The capillary structure is usually a grooved structure, a sintered powder structure or a wire mesh structure. . Among them, the wire mesh structure is gradually replaced by other forms of liquid-absorbent cores due to poor process repeatability and inability to adapt to the bending of the...

Problems solved by technology

The latest research shows that the internal structure of heat pipes will become more and more complex

For example, the spiral power heat pipe disclosed in patent application 201611099102.9 is used for large-scale device systems. Many components are integrated in the disclosed technical solution. If the traditional method of welding and sealing the tube body is adopted, it will be extremely unfavorable for the subsequent repair of the internal components of the tube body. detection
