Description
Technical Field
The invention relates to a cross-woven capillary structure and a heat pipe structure thereof, in particular to a cross-woven capillary structure and a heat pipe structure thereof, which can greatly increase the supporting strength and have different capillary forces.
Background
With the increasing miniaturization and high performance of computers, smart electronic devices and other electrical appliances, the heat transfer elements and heat dissipation elements used therein need to be designed in the direction of miniaturization and thinning to meet the needs of users.
A heat pipe is a heat-conducting element having excellent heat-conducting efficiency, and the heat-conducting efficiency is several times or more than ten times higher than that of metals such as copper and aluminum, and therefore, the heat pipe is used as a cooling element in various heat-related devices.
The conventional heat pipe structure has various manufacturing methods, such as filling metal powder into a hollow pipe, forming a capillary structure layer on the inner wall of the hollow pipe by sintering the metal powder, then vacuuming the pipe, filling a working fluid, and finally sealing the pipe, or placing a metal mesh into the hollow pipe, wherein the mesh capillary structure is unfolded and naturally extended outward to be attached to the inner wall of the hollow pipe to form a capillary structure layer, and then vacuuming the pipe, filling the working fluid, and finally sealing the pipe.
The flat heat pipe can achieve the purpose of thinning, but has another problem that, because the flat heat pipe is formed by sintering metal powder on the inner wall surface of the pipe diameter of the heat pipe, the sintered body can be completely and completely covered on the wall surface, when the flat heat pipe is pressurized, the capillary structures (namely the sintered metal powder or the reticular capillary structure body) positioned at two sides of the pressurized surface in the flat heat pipe are easy to be extruded and damaged, and then fall off from the inner wall of the flat heat pipe, so that the heat transfer efficiency of the thin heat pipe is greatly reduced or even disabled; in addition, although the flat heat pipe can achieve heat source conduction, the flat heat pipe has insufficient capillary force of the internal capillary structure due to the thinning purpose after being thinned, and the capillary force is reduced due to the reduction of the flow passage area in the pipe during the thinning processing of the flat heat pipe, so that the maximum heat transfer amount is also reduced.
As mentioned above, the prior art has the following disadvantages:
1. the supporting force of the traditional heat pipe is weak;
2. the capillary transfer force is less effective.
Therefore, how to solve the above problems is a direction in which the inventors desire to research and improve the above problems and related manufacturers in the industry.
