Radiating fin assembly for thermal module

Abstract

A radiating fin assembly for a thermal module includes a plurality of radiating fins being mounted on a top of a heat radiating base of the thermal module with a heat pipe located between the radiating fins and the base. Each of the radiating fins is provided at a lower side with a flange for contacting with the base and a downward opened curved notch for engaging with the heat pipe. A curved extension is provided along an outer edge of the curved notch to outward extend and downward incline from the radiating fin. When the radiating fin assembly is mounted on the top of the heat radiating base, the curved extensions apply a uniformly distributed downward pressure to the heat pipe, bringing the heat pipe to more tightly contact with the heat radiating base.

1 . A radiating fin assembly for a thermal module, the thermal module including a heat radiating base, on a top of which the radiating fin assembly is mounted with a heat pipe located between the radiating fin assembly and the heat radiating base; the radiating fin assembly comprising a plurality of parallelly arranged radiating fins, each of the radiating fins having a lower side being bent to form a flange, and having a downward opened curved notch formed on the same lower side with the flange, and the curved notch being provided along an outer edge with a curved extension outward extended and downward inclined from the radiating fin; the curved extensions being adapted to fitly engage with an upper portion of the heat pipe when the radiating fin assembly is mounted on the top of the heat radiating base, and thereby apply a downward pressure to the heat pipe, bringing the heat pipe to more tightly contact with the heat radiating base. 
   
   
       2 . The radiating fin assembly for a thermal module as claimed in  claim 1 , wherein a cut of a predetermined size is provided between each of two ends of the curved extension and the flange on each of the radiating fins, so that the curved extension possesses enhanced elasticity when applying the downward pressure against the heat pipe.
