Heat dissipation device

Abstract

A heat dissipation device includes a frame and a number of fans mounted to the frame. The frame includes a base and a number of rods extending from a center of the base in a same direction. The base defines a through hole in each of four corners. Each rod defines a slot adjacent to a distal end of the rod away from the base. Each fan includes a board defining a through hole in each of four corners. The rods extend through the corresponding through holes of the fans. A fixing member is engaged in the slots of the posts, to sandwich the fans together with the base.

1 . A heat dissipation device, comprising:
 a frame comprising a base and a plurality of rods extending from the base;   a plurality of fans each comprising a board, the board defining a fixing hole in a corner; and   a fixing member;   wherein the rods extend through the fixing holes of the fans, the fixing member is fixed to distal ends of the rods opposite to the base to sandwich the fans together with the base.   
     
     
         2 . The heat dissipation device of  claim 1 , wherein the fixing member is a loop, and defines an opening in one side of the loop, a tab extends from the side bounding the opening. 
     
     
         3 . The heat dissipation device of  claim 1 , wherein the frame further comprises a bracket, the base defines an opening, the bracket is arranged in the opening and connected to sides of the base bounding the opening with ends of the bracket, a supporting portion is formed on a center of the bracket; the rods extend from the supporting portion. 
     
     
         4 . The heat dissipation device of  claim 3 , wherein each fan further defines fixing holes in other corners of the board, a holding piece is formed on a conjunction of each side of the base and a corresponding end of the bracket, two spaced protrusions protrude from each holding piece and are engaged in corresponding the through holes of two adjacent fans. 
     
     
         5 . The heat dissipation device of  claim 1 , wherein, each rod defines a slot adjacent to the distal end of the rod, the fixing member is engaged in the slots of the rods. 
     
     
         6 . A heat dissipation device, comprising:
 a frame comprising a base and four rods extending from the base;   four fans each comprising a board, the board defining a fixing hole in a corner; and   a fixing member;   wherein the rods extend through the fixing holes of the fans, the fixing member is fixed to distal ends of the rods opposite to the base to sandwich the fans together with the base.   
     
     
         7 . The heat dissipation device of  claim 6 , wherein the fixing member is a loop, and defines an opening in one side of the loop, a tab extends from the side bounding the opening. 
     
     
         8 . The heat dissipation device of  claim 6 , wherein the frame further comprises a cross-shaped bracket, the base defines an opening, the bracket is arranged in the opening and connected to sides of the base bounding the opening with ends of the bracket, a supporting portion is formed on a center of the bracket; the rods extend from the supporting portion. 
     
     
         9 . The heat dissipation device of  claim 8 , wherein each fan further defines fixing holes in other corners of the board, a holding piece is formed on a conjunction of each side of the base and a corresponding end of the bracket, two spaced protrusions protrude from each holding piece and are engaged in corresponding the through holes of two adjacent fans. 
     
     
         10 . The heat dissipation device of  claim 6 , wherein, each rod defines a slot adjacent to the distal end of the rod, the fixing member is engaged in the slots of the rods.
