Heat dissipation apparatus

Abstract

A heat dissipation apparatus includes a heat sink, a resilient pressing member, and two fasteners. The pressing member includes an abutting portion to press the heat sink, and two locking portions extending from opposite ends of the abutting portion. The fasteners are respectively latched to the locking portions. When the heat sink is mounted to a heat-generating component by the fasteners, the abutting portion is stretched to be resiliently flexed by the locking portions latched by the fasteners. The abutting portion abuts against the heat sink toward the heat-generating component, thereby urging the heat sink to be in intimate thermal contact with the heat-generating component.

1 . A heat dissipation apparatus comprising:
 a heat sink;   a resilient pressing member comprising an abutting portion to press the heat sink, and two locking portions extending from opposite ends of the abutting portion; and   two fasteners latched to the locking portions, respectively;   wherein when the heat sink is mounted to a heat-generating component by the fasteners, the abutting portion is stretched to be resiliently flexed by the locking portions latched by the fasteners, the abutting portion abuts against the heat sink toward the heat-generating component, thereby urging the heat sink to be in intimate thermal contact with the heat-generating component.   
     
     
         2 . The heat dissipation apparatus of  claim 1 , wherein each of the fasteners comprises a body and a catch extending from a first end of the body; the catches of the fasteners are hollowed to be readily flexed. 
     
     
         3 . The heat dissipation apparatus of  claim 2 , wherein two opposite cutouts are defined in a conjunction of the body and the catch of each of the fasteners. 
     
     
         4 . The heat dissipation apparatus of  claim 2 , wherein a latching hole is defined in a second end of the body opposite to the first end of each of the fasteners, and the locking portions are latched in the latching holes of the fasteners, respectively. 
     
     
         5 . The heat dissipation apparatus of  claim 1 , wherein the heat sink comprises a thermal-conductive base, and a plurality of thermal-conductive fins extending from a top of the base; two fixing holes are respectively defined in the base, the fasteners respectively extend through the fixing holes. 
     
     
         6 . The heat dissipation apparatus of  claim 5 , wherein two support portions are respectively formed at opposite ends of the base, the fixing holes are respectively defined in the support portions. 
     
     
         7 . The heat dissipation apparatus of  claim 5 , wherein a receiving groove is transversely defined in the fins and extends along a length direction of the base, the abutting portion is received in the receiving groove. 
     
     
         8 . The heat dissipation apparatus of  claim 1 , wherein the abutting portion is arc-shaped, with the opposite ends of the abutting portion tilted relative to a center of the abutting portion. 
     
     
         9 . The heat dissipation apparatus of  claim 1 , wherein the locking portions are substantially V-shaped.
