Including evaporation part, insulation part, condensation part and porous sintered powder capillary.For the degree of porosity and transmission for increasing capillary pipe structure object
Rate configures the porous of the different material for being suitble to respective requirement condition, shape or particle size in evaporation part, insulation part, condensation part
It is sintered powder capillary pipe structure.Another feature is, for the porous sintered powder capillary of configuration different material, image or particle size
Pipe structure, by this powder technique, gas cell distribution be it is double, thus heat pipe have radially, asymmetric end surface shape.
Above-mentioned heat pipe has been all made of compound capillary structure, and mainly by using different structure or the capillary material of type
Material can improve heat-conductive characteristic, but process is relative complex and production cost also will increase to realize to a certain extent.
Summary of the invention
In view of the deficiencies of the prior art, the utility model proposes a kind of simple process, without annealing, production cost compared with
