Vapor chamber structure

Abstract

A vapor chamber structure for at least one heating element includes a main body having a heat receiving plate. The heat receiving plate has at least one wrinkled ring portion. An inner portion of the wrinkled ring portion surrounds a contact portion. The contact portion is in contact with the heating element. Thereby, one heating element provides the contact portion a thrust when the contact portion is in contact with the heating element. The wrinkled ring portion is therefore forced to deform for helping the contact portion slightly adjust its position. This ensures a tight and even contact between the contact portion and the heating element, thereby improving the heat dissipation efficiency of the vapor chamber structure.

What is claimed is: 
     
         1 . A vapor chamber structure, configured for at least one heating element, comprising:
 a main body having a heat receiving plate, the heat receiving plate having at least one wrinkled ring portion, an inner portion of the wrinkled ring portion surrounding a contact portion, and the contact portion being in contact with the heating element.   
     
     
         2 . The vapor chamber structure according to  claim 1 , wherein the heat receiving plate has at least one convex portion protruding therefrom, the wrinkled ring portion is formed on an outer edge of the convex portion while the contact portion is formed on a top of the convex portion. 
     
     
         3 . The vapor chamber structure according to  claim 1 , wherein the heat receiving plate has at least one convex portion and at least one block portion protruding therefrom, the wrinkled ring portion is formed on an outer edge of the convex portion while the contact portion is formed on a top of the convex portion. 
     
     
         4 . The vapor chamber structure according to  claim 3 , wherein the heat receiving plate has a convex section protruding therefrom, the convex section is disposed with at least one recessed ring groove, the convex portion is formed inside a region surrounded by the recessed ring groove while the block portion is formed outside the region surrounded by the recessed ring groove. 
     
     
         5 . The vapor chamber structure according to  claim 1 , wherein the wrinkled ring portion comprises a plurality of recessed ring sections recessed on the heat receiving plate, and the recessed ring sections are in annular arrangement in sequence. 
     
     
         6 . The vapor chamber structure according to  claim 1 , wherein the thickness of each recessed ring section is less than the thickness of the heat receiving plate. 
     
     
         7 . The vapor chamber structure according to  claim 1 , wherein the main body has a condensing plate arranged in a way corresponding to the heat receiving plate, the condensing plate forms a plurality of stop sticks extending towards the heat receiving plate, and a gap s is formed between each stop stick and the contact portion. 
     
     
         8 . The vapor chamber structure according to  claim 1 , wherein the main body has a condensing plate arranged in a way corresponding to the heat receiving plate, the condensing plate forms a plurality of stop sticks extending towards the heat receiving plate, an outer edge of each stop stick is disposed with a shrunken ring groove, and each stop stick abuts on the contact portion. 
     
     
         9 . The vapor chamber structure according to  claim 8 , further comprising a plurality of cooling fins and a plurality of return springs, the inner portion of each stop stick forms a concave corresponding to the condensing plate, the cooling fins are connected to the condensing plate and cover the concave, each return spring is accommodated in each concave, and each return spring is sandwiched between the cooling fin and the stop stick. 
     
     
         10 . The vapor chamber structure according to  claim 7 , wherein each stop stick is formed by stamping in a direction towards the heat receiving plate from the condensing plate, and the inner portion of each stop stick forms a concave corresponding to the condensing plate. 
     
     
         11 . The vapor chamber structure according to  claim 7 , further comprising a plurality of cooling fins, wherein the cooling fins are connected to the condensing plate and cover the concave. 
     
     
         12 . The vapor chamber structure according to  claim 7 , wherein the main body comprises an upper case and a lower case assembled to each other, an accommodating chamber is formed between the upper case and the lower case, the heat receiving plate is formed on the lower case while the condensing plate is formed on the upper case. 
     
     
         13 . The vapor chamber structure according to  claim 12 , further comprising a capillary structure, wherein the capillary structure is accommodated in the accommodating chamber and covers the heat receiving plate.
