Description
Technical field
The present invention relates to a kind of heat pipe and manufacture method thereof, particularly a kind of flat plate heat tube and manufacture method thereof.
Background technology
At present industry generally adopts heat pipe to solve the high density heat dissipation problem of high-speed computer, as heat pipe, loop hot-pipe and flat plate heat tube products such as (Vapor Chamber).
The operation principle of flat plate heat tube is identical with conventional heat pipe, because of it has the heat transfer area bigger than conventional heat pipe, and meets the high practical value of " light, thin, short, little ", and is widely applied on the electronic product with big radiating surface.
As shown in Figures 1 and 2, general flat plate heat tube has a upper cover plate 100 for preparing with the punching press processing procedure, the lower cover 101 and the capillary structure 102 between upper cover plate 100, lower cover 101 that cooperate with upper cover plate 100, and cover plate was 100,101 about some hydraulic fluids were filled to.The consistency of thickness of this capillary structure 102.These lower cover 101 middle parts have protruded out an endothermic section 103 downwards, in order to contact with heat-generating electronic elements.Capillary structure 102 is attached at the inner surface of lower cover 101 and endothermic section 103.Behind the heat that endothermic section 103 absorption heat-generating electronic elements send, the capillary structure 102 interior hydraulic fluids that are attached at endothermic section 103 evaporate to take away heat.At this moment, if capillary structure 102 is too thick, the bubble that hydraulic fluid evaporation is produced makes formation one vapor film between the upper surface of capillary structure 102 and lower cover 101, thereby has strengthened the thermal resistance of heat pipe, and then causes the temperature of lower cover 101 to rise rapidly and cause the heat pipe scaling loss.If capillary structure 102 is too thin, the back-flow velocity of the too fast and condensed hydraulic fluid of hydraulic fluid evaporation is slower, thereby makes capillary structure 102 that drying even scaling loss take place, thereby influences the service behaviour of heat pipe.
Therefore, how to make the flat plate heat tube of best capillary structure, real is the problem that relevant dealer endeavours to solve.
Summary of the invention
In view of this, be necessary to provide a kind of the have heat pipe of thick, as to approach variation capillary structure and the manufacture method of this heat pipe.
A kind of flat plate heat tube, comprise a lower cover, a upper cover plate that cooperates with lower cover and be attached at a capillary structure of lower cover inner surface, two extensions that described lower cover comprises the endothermic section that contacts with thermal source, is inclined upwardly and extends from the endothermic section opposite end, described capillary structure comprises one first capillary section that the endothermic section with lower cover is sticked and the 2 second capillary sections that are sticked with the extension of lower cover, the thickness of the described first capillary section is little than the second capillary section, and successively decreases to relative both sides in the thickness of second capillary section middle part.
A kind of manufacture method of flat plate heat tube, may further comprise the steps: (1) provides a lower cover and the upper cover plate that cooperates with lower cover, this lower cover have a level the endothermic section, from the endothermic section opposite end be tilted to, outward extending two extensions reach from outward extending two joint portions of extension level; (2) provide the number of metal powder; (3) provide a mould, this mould comprises that one encloses upper cover plate in it and the upper mould cover of an end opening and is to establish in it and the following die cap of an end opening with lower cover, and metal-powder is filled in the mould; (4) high temperature sintering lower cover, upper cover plate and mould, make metal-powder sintering in the mould form one first capillary structure continuous, that be attached at the lower cover upper surface and be attached at one second capillary structure of upper cover plate lower surface, described first capillary structure comprises the one first capillary section that is attached at the lower cover endothermic section, the 2 second capillary sections that are attached at extension, and the described first capillary section is thin than the second capillary section; (5) take out mould, and upper cover plate and lower cover are made up to obtain the flat plate heat tube of present embodiment.
Compared with prior art, the first capillary section of first capillary structure of flat plate heat tube of the present invention is thin than the second capillary section, when flat plate heat tube uses, behind the heat that the endothermic section of first capillary section absorption lower cover absorbs, these heats of the rapid evaporator strip of working solution physical efficiency in it, and the working solution physical efficiency that stores in the second capillary section flows to the first capillary section rapidly, makes flat plate heat tube that scaling loss not take place, thereby has guaranteed the heat transfer property of flat plate heat tube.
