Structure for holding a heat pipe to a base

Abstract

A structure for holding a heat pipe to a base includes a base and a heat pipe. The base has a first side and an opposite second side, and is formed at a middle portion with a receiving recess, such that two sidewalls are raised from two lateral sides of the receiving recess. Each of the sidewalls has at least one projected section formed using a part material of the base, such that portions of the base adjacent to the projected sections respectively form an opening. The heat pipe is laid in the receiving recess and has a top and a bottom surface. The projected sections are bent to flatly press against the top surface of the heat pipe to firmly hold the heat pipe to the base. Since the projected sections are formed using a part material of the base, the holding structure is manufactured at largely reduced cost.

What is claimed is: 
     
         1 . A structure for holding a heat pipe to a base, comprising:
 a base having a first side and an opposite second side, and being formed at a middle portion with a receiving recess, such that a sidewall is raised from either lateral side of the receiving recess; each of the sidewalls having at least one upward projected section formed using a part material of the base, such that portions of the base adjacent to the projected sections respectively forming an opening; and   a heat pipe being laid in the receiving recess and having a top surface and a bottom surface; and the projected sections being bent to flatly press against the top surface of the heat pipe.   
     
     
         2 . The holding structure as claimed in  claim 1 , wherein the openings are extended from the first side to the second side to penetrate through the base. 
     
     
         3 . The holding structure as claimed in  claim 1 , wherein the top surface of the heat pipe is flush with the first side of the base. 
     
     
         4 . The holding structure as claimed in  claim 1 , wherein the base is shaped through a mechanical process. 
     
     
         5 . The holding structure as claimed in  claim 4 , wherein the mechanical process is stamping. 
     
     
         6 . The holding structure as claimed in  claim 1 , wherein the heat pipe and the base are held together through a mechanical process. 
     
     
         7 . The holding structure as claimed in  claim 6 , wherein the mechanical process is selected from the group consisting of stamping and rolling. 
     
     
         8 . The holding structure as claimed in  claim 1 , wherein the heat pipe is a flat heat pipe. 
     
     
         9 . The holding structure as claimed in  claim 1 , wherein the projected section has a shape selected from the group consisting of a rectangular, a round, a triangular and any other geometrical shape. 
     
     
         10 . The holding structure as claimed in  claim 1 , wherein the base is formed at an area adjacent to one sidewall of the receiving recess with a through hole, and the projected section is formed on the other sidewall of the receiving recess corresponding to the through hole, such that the projected section flatly pressed against the top surface of the heat pipe has a free end extended into the through hole. 
     
     
         11 . The holding structure as claimed in  claim 1 , wherein portions of the base located at two lateral sides of the receiving recess form two raised open surfaces, and the openings being formed on the two open surfaces. 
     
     
         12 . The holding structure as claimed in  claim 1 , wherein the openings are formed on the sidewalls at positions corresponding to the projected sections.
