Covered plate-type heat pipe

Abstract

A compact plate-type heat pipe having a large strength includes a plate-type heat pipe having a vaporized end and a condensed end and a metallic plate-like sleeve. The plate-like sleeve is covered outside the plate-type heat pipe tightly with the vaporized end of the plate-type heat pipe being exposed to the outside. The surface of the vaporized end of the plate-type heat pipe is adhered to the surface of a heat-generating electronic element, so that the heat generated by the heat-generating electronic element can be dissipated quickly.

1 . A covered plate-type heat pipe, comprising:
 a plate-type heat pipe having a vaporized end and a condensed end; and   a plate-like sleeve covering the plate-type heat pipe tightly with the vaporized end of the plate-type heat pipe being exposed to the outside.   
     
     
         2 . The covered plate-type heat pipe according to  claim 1 , wherein the plate-type heat pipe is provided therein with a wick structure and a working fluid. 
     
     
         3 . The covered plate-type heat pipe according to  claim 1 , wherein the plate-like sleeve is made by one of Al, Al—Mg alloy and Ti. 
     
     
         4 . The covered plate-type heat pipe according to  claim 1 , wherein the plate-like sleeve has therein a heat-conducting medium that is distributed between the plate-type heat pipe and the plate-like sleeve uniformly. 
     
     
         5 . A process for manufacturing a covered plate-type heat pipe, comprising the steps of:
 providing a plate-type heat pipe having a vaporized end and a condensed end;   refrigerating the plate-type heat pipe to reduce a volume thereof;   providing a plate-like sleeve;   heating the plate-like sleeve to expand a volume thereof; and   covering the refrigerated plate-type heat pipe by the heated plate-like sleeve with the vaporized end of the plate-type heat pipe being exposed to the outside;   whereby after returning to room temperature, the plate-like sleeve contracts to cover outside the plate-type heat pipe tightly.   
     
     
         6 . The process according to  claim 5 , wherein the plate-type heat pipe is provided therein with a wick structure and a working fluid to form a vacuum chamber. 
     
     
         7 . The process according to  claim 5 , wherein the plate-like sleeve further comprises a heat-conducting medium, after the plate-like sleeve is covered outside the plate-type heat pipe, the heat-conducting medium is distributed uniformly between the plate-type heat pipe and the plate-like sleeve.
