Heat sink assembly

Abstract

A heat sink assembly includes a heat sink and a number of protecting members. The heat sink includes a number of parallel fins. The fins form a fin assembly including a number of lengthwise corners at lateral sides of the fin assembly. Each lengthwise corner is covered by one of the protecting members. Each protecting member includes a first stop plate and a second stop plate engaging with two adjacent sides of the fin assembly, and a number of pairs of connecting plates between the first and second stop plates, at opposing ends of the first and second stop plates. A slot is bounded by each pair of connecting plates. The corners of the fins on upper and lower portions of the fin assembly engage and are retained by the slots in upper and lower portions of the protecting members.

What is claimed is: 
     
         1 . A heat sink assembly, comprising:
 a heat sink comprising a base, at least one heat pipe connected to the base, and a plurality of fins parallel to the base and connected to said at least one heat pipe, each of the fins comprising a plurality of corners, the fins being aligned and overlapped with one another and forming a fin assembly comprising a plurality of lengthwise corners at lateral sides of the fin assembly, each lengthwise corner being formed by a plurality of the corners of the fins; and   a plurality of protecting members, wherein each lengthwise corner of the fin assembly is covered by a corresponding one of the protecting members, each protecting member comprises a first stop plate and a second stop plate respectively engaging with two adjacent sides of the fin assembly, and a plurality of pairs of connecting plates connected between inner sides of the first and second stop plates, at opposite ends of the first and second stop plates, a slot is bounded by each pair of connecting plates, the corners of the fins forming the corresponding lengthwise corner at upper and lower portions of the fin assembly respectively engage in the slots in upper and lower portions of the protecting members.   
     
     
         2 . The heat sink assembly of  claim 1 , wherein the fins have a same shape, and the number of the lengthwise corners is equal to the number of the corners of each fin. 
     
     
         3 . The heat sink assembly of  claim 2 , wherein each fin is quadrate and comprises four corners, the fin assembly comprises four lengthwise corners at lateral sides of the fin assembly, the number of the protecting members is four, the four protecting members respectively cover on the four lengthwise corners of the fin assembly. 
     
     
         4 . The heat sink assembly of  claim 3 , wherein the first and second stop plates of each protecting member are perpendicular to each other, and each pair of connecting plates is perpendicularly connected between the corresponding first and second stop plates. 
     
     
         5 . The heat sink assembly of  claim 1 , wherein said at least one heat pipe is perpendicularly connected to the base and the fins. 
     
     
         6 . The heat sink assembly of  claim 1 , wherein the protecting members are made of plastic.
