Flat type heat pipe device

Abstract

A flat type heat pipe device includes a packaging unit and a bonding member. The packaging unit further includes a first shell member and a second shell member. The first shell member has a work zone, a first joining part surrounding the work zone and an upright stop part disposed between the work zone and the joining part. The second shell member provides a shape corresponding to the first shell member to cover the first shell member and has a shell lid part spacing apart from the work zone and a second joining part disposed on the first joining part. The bonding member is disposed between the first joining part and the second joining part to adhere the first joining part to the second joining part. When the first shell member is pressingly fit with second shell member, the stop part is capable of preventing the bonding member from entering the packaging unit.

1 . A flat type heat pipe device comprising:
 a packaging unit; and   a bonding member;   wherein the packaging unit further comprises:   a first shell member, having a work zone, a first joining part surrounding the work zone and an upright stop part disposed between the work zone and the joining part;   a second shell member, providing a shape corresponding to the first shell member, covering the first shell member, having a shell lid part spacing apart from the work zone and a second joining part disposed on the first joining part; and   the bonding member is disposed between the first joining part and the second joining part for adhering the first joining part to the second joining part.   
     
     
         2 . The flat type heat pipe device as defined in  claim 1 , wherein the stop part has an elongated channel shaped cross section with an upright inner section, a top section and an upright outer section. 
     
     
         3 . The flat type heat pipe device as defined in  claim 1 , wherein the first joining part and the second joining part are a horizontal wall respectively. 
     
     
         4 . The flat type heat pipe device as defined in  claim 1 , wherein the shell lid part has a top side greater than the work zone and a vertical wall extending from periphery of the top side and being disposed outer side of the stop part. 
     
     
         5 . The flat type heat pipe device as defined in  claim 1 , wherein the work zone is disposed at an elevation the same as the first joining part. 
     
     
         6 . The flat type heat pipe device as defined in  claim 1 , wherein the work zone is disposed at an elevation different from the first joining part. 
     
     
         7 . The flat type heat pipe device as defined in  claim 1 , wherein at least either the first joining part or the second joining part has a groove extending the periphery thereof. 
     
     
         8 . The flat type heat pipe device as defined in  claim 1 , wherein at least either the first joining part or the second joining part has a groove extending the periphery thereof to receive a seal ring. 
     
     
         9 . The flat type heat pipe device as defined in  claim 1 , wherein the first joining part has a first channel extending to the work zone from the periphery thereof and a filling pipe is received in the first channel with a closed end of the filling pipe being away from the work zone. 
     
     
         10 . The flat type heat pipe device as defined in  claim 9 , wherein the second joining part has a second channel corresponding to the first channel for accommodating the filling pipe. 
     
     
         11 . The flat type heat pipe device as defined in  claim 1  further comprises a capillary device is disposed in a chamber defined by the work zone and the shell lid part. 
     
     
         12 . The flat type heat pipe device as defined in  claim 11  further comprises a work fluid disposed in the chamber. 
     
     
         13 . The flat type heat pipe device as defined in  claim 1 , wherein the first shell member and the second shell member are made of aluminum or copper. 
     
     
         14 . The flat type heat pipe device as defined in  claim 1 , wherein the bonding member is soldering wire, glue or adhesives. 
     
     
         15 . The flat type heat pipe device as defined in  claim 1 , wherein the bonding paste is soldering paste.
