Heat dissipating assembly

Abstract

A heat dissipating assembly includes a heat exchanger and a base. The heat exchanger defines at least one latching slot. A touching piece is surrounded the latching slot. The base includes at least one latching post. The touching piece is resiliently deformable to engage the at least one latching post in the at least one latching slot. The touching piece abuts the at least one latching post.

         5 . The heat dissipating assembly of  claim 4 , wherein a size of the head portion is greater than a size of the neck portion. 
     
     
         6 . The heat dissipating assembly of  claim 5 , wherein a size of the wide portion is greater than a size of the narrow portion, and the size of the head portion is greater than the size of the wide portion. 
     
     
         7 . The heat dissipating assembly of  claim 2 , wherein the base further comprising a board, each of the first fin and the plurality of second fins comprising a flange, and the flange abuts the board. 
     
     
         8 . The heat dissipating assembly of  claim 1 , wherein the at least one latching post comprises three latching posts, and each of the three latching posts has a first extending direction, and the first extending directions are parallel to each other. 
     
     
         9 . The heat dissipating assembly of  claim 1 , wherein the at least one latching slot comprises three latching slots, each of the three latching slots has a second extending direction, and the second extending directions are parallel to each other. 
     
     
         10 . A heat dissipating assembly, comprising:
 a heat exchanger defining at least one latching slot; the at least one latching slot comprises a narrow portion and a wide portion communication with the wide portion, a touching piece surrounding the at least one latching slot; and   a base comprising at least one latching post, the at least one latching post comprises a head portion and neck portion connected to the head portion; the head portion extends through the narrow portion to be engaged in the wide portion, and the neck portion is engaged in the narrow portion, to secure the at least one latching slot to secure the heat exchanger to the base; and the touching piece abuts the at least one latching slot.   
     
     
         11 . The heat dissipating assembly of  claim 10 , wherein the heat exchanger comprising a first fin and a plurality of second fins, the first fin defines a cutout, an engaging portion extends from each of the plurality of second fins, and one of the plurality of second fins is elastically engaged in the cutout to secure the one of the plurality of second fins to the first fin. 
     
     
         12 . The heat dissipating assembly of  claim 11 , wherein each of the plurality of second fins defines a cutout, the cutout of one of the second fins receives the engaging portion of adjacent second fin, to secure two adjacent second fins together. 
     
     
         13 . The heat dissipating assembly of  claim 10 , wherein a size of the head portion is greater than a size of the neck portion. 
     
     
         14 . The heat dissipating assembly of  claim 13 , wherein a size of the wide portion is greater than a size of the narrow portion, and the size of the head portion is greater than the size of the wide portion. 
     
     
         15 . The heat dissipating assembly of  claim 11 , wherein the base further comprises a board, each of the first fin and the plurality of second fins comprising a flange, and the flange abuts the board. 
     
     
         16 . The heat dissipating assembly of  claim 10 , wherein the at least one latching post comprises three latching posts, and each of the three latching posts has a first extending direction, and the first extending directions are parallel to each other. 
     
     
         17 . The heat dissipating assembly of  claim 10 , wherein the at least one latching slot comprises three latching slots, each of the three latching slots has a second extending direction, and the second extending directions are parallel to each other.
