Vapor chamber having sealing structure

Abstract

A vapor chamber having sealing structure, comprising a body and a capillary wick. The body has a first plate and a second plate. The first and second plates are attached to each other, which collectively define a sealed chamber therein and form a lip side. The lip side has an inlet channel and a stamping seal. The inlet channel is connected to the sealed chamber at one end and is connected to the stamping seal at the other end. The stamping seal is formed in a non-I shape. The capillary wick is selectively disposed within the sealed chamber of the body. Therefore, the air-tightness of the vapor chamber is increased by the stamping seal.

What is claimed is: 
     
         1 . A vapor chamber having sealing structure, comprising:
 a body having a first plate and a second plate, the first and second plates attached to each other collectively defining a sealed chamber therein and forming a lip side, the lip side having a inlet channel and a stamping seal, the inlet channel connected to the sealed chamber at one end and connected to the stamping seal at the other end, the stamping seal being formed in a non-I shape; and   a capillary wick selectively disposed within the sealed chamber of the body.   
     
     
         2 . The vapor chamber having sealing structure according to  claim 1 , wherein the stamping seal is formed in a Ω shape, an upside-down U shape, a U shape, a horseshoe shape, an X shape, a C shape, a wave shape, or a Union Jack shape. 
     
     
         3 . The vapor chamber having sealing structure according to  claim 1 , wherein the lip side surrounds the outer perimeter of the sealed chamber. 
     
     
         4 . The vapor chamber having sealing structure according to  claim 1 , wherein the stamping seal is lower than the height of the lip side of the first plate. 
     
     
         5 . The vapor chamber having sealing structure according to  claim 1 , wherein the first plate has a first surface and a second surface, and the second plate has a third surface and a fourth surface, wherein a groove and the inlet channel are defined by a structure that protrudes upwardly from the first surface to the second surface of the first plate, and wherein the groove forms the sealed chamber when the first and second plates are combined together. 
     
     
         6 . The vapor chamber having sealing structure according to  claim 1 , wherein the entire sealed chamber is filled with the capillary wick which is disposed in between the first and second plates. 
     
     
         7 . The vapor chamber having sealing structure according to  claim 1 , wherein the capillary wick is disposed on either the first surface of the first plate or the third surface of the second plate, or both the first and third surfaces of the first and second plates. 
     
     
         8 . The vapor chamber having sealing structure according to  claim 5 , wherein the second and fourth surfaces are disposed on the upper and lower sides of the body, respectively, in which the second surface is defined as a condensation surface, and the fourth surface is defined as a heat absorption surface. 
     
     
         9 . The vapor chamber having sealing structure according to  claim 1 , wherein the stamping seal is recessed into both the first and second plates, and is lower than the height of the lip side of the first and second plates. 
     
     
         10 . The vapor chamber having sealing structure according to  claim 1 , wherein corresponding first cutout and second cutout are disposed adjacent to the stamping seal on the lip side of the first and second plates. 
     
     
         11 . The vapor chamber having sealing structure according to  claim 1 , wherein the first and second plates are aluminum, copper, commercially pure titanium, aluminium alloy, copper alloy, ceramics, stainless steel, or any combination thereof. 
     
     
         12 . The vapor chamber having sealing structure according to  claim 1 , wherein the first surface of the first plate is provided with a plurality of recesses that extends from the first surface to a side of the capillary wick in a direction toward to the groove. 
     
     
         13 . The vapor chamber having sealing structure according to  claim 1 , wherein the body  1  is provided with a tube that is connected to the inlet channel, and a portion of the tube becomes flat upon the formation of the stamping seal.
