Three-dimensional vapor chamber assembly structure

Abstract

A three-dimensional vapor chamber assembly structure includes a housing, heat pipes, a capillary member and a working fluid. The housing includes a first housing plate and a second housing plate, a cavity formed between the first and second housing plates, and through holes formed on the second housing plate. The heat pipe penetrates through the through holes and includes an open end having a flange formed thereon. The flange includes lateral and longitudinal surfaces. The lateral surface of the flange is attached to the second housing plate via a welding layer, and the longitudinal surface of the flange is attached to the second housing plate via a welding product. The capillary member is arranged inside the cavity and attached to the housing. The working fluid is arranged inside the cavity. Accordingly, a firm and robust vapor chamber structure capable of preventing welding material from entering the cavity is achieved.

What is claimed is: 
     
         1 . A three-dimensional vapor chamber assembly structure, comprising:
 a housing, comprising a first housing plate and a second housing plate attached to and sealed with the first housing plate correspondingly, a cavity defined between the first housing plate and the second housing plate, and a plurality of through holes defined on the second housing plate;   a plurality of heat pipes, inserted in the through holes correspondingly, each of the heat pipes comprising an open end and a flange disposed adjacent to the open end, the flange comprising a lateral surface and a longitudinal surface; wherein the lateral surface of the flange is attached to the second housing plate via a welding layer, and the longitudinal surface of the flange is attached to the second housing plate via a welding product;   a capillary member, arranged in the cavity and attached to the housing; and   a working fluid, arranged inside the cavity.   
     
     
         2 . The three-dimensional vapor chamber assembly structure according to  claim 1 , wherein the welding layer is formed in a resistance welding manner. 
     
     
         3 . The three-dimensional vapor chamber assembly structure according to  claim 1 , wherein the welding product is formed in a laser welding manner. 
     
     
         4 . The three-dimensional vapor chamber assembly structure according to  claim 1 , wherein a recessed groove is defined on an outer periphery of each of the through holes of the second housing plate, and the flange is received in the recessed groove. 
     
     
         5 . The three-dimensional vapor chamber assembly structure according to  claim 4 , wherein the second housing plate comprises a top sheet, and the top sheet comprises a protrusion disposed protrusively from an outer surface of the top sheet corresponding to the recessed groove. 
     
     
         6 . The three-dimensional vapor chamber assembly structure according to  claim 1 , wherein the second housing plate comprises an inner flat surface, and the lateral surface of the flange is flatly attached to the inner flat surface. 
     
     
         7 . The three-dimensional vapor chamber assembly structure according to  claim 6 , wherein the welding product is disposed between the longitudinal surface and the inner flat surface. 
     
     
         8 . The three-dimensional vapor chamber assembly structure according to  claim 1 , wherein the flange extends from the open end of the heat pipe in a diameter-increasing manner, and the flange is arranged perpendicular to a center line of the heat pipe. 
     
     
         9 . The three-dimensional vapor chamber assembly structure according to  claim 1 , wherein a circumferential wall is disposed extensively from a circumference of each of the through holes of the second housing plate, and each of the heat pipes is inserted through the circumferential wall. 
     
     
         10 . The three-dimensional vapor chamber assembly structure according to  claim 9 , wherein a sealing layer is disposed between each of the heat pipes and the circumferential wall. 
     
     
         11 . The three-dimensional vapor chamber assembly structure according to  claim 1 , further comprising a plurality of supporting columns, the supporting columns arranged spacedly in the cavity and disposed perpendicularly between the first housing plate and the second housing plate. 
     
     
         12 . The three-dimensional vapor chamber assembly structure according to  claim 1 , further comprising a heat sink mounted on each of the heat pipes.
