Specific embodiment
Technical solution of the present invention is described in further details with reference to the accompanying drawings and examples, following embodiment is not constituted
Limitation of the invention.
As shown in Figure 1, radiator 4 safe and reliable is fixed on 1 table of chip by the fixer for heat radiator 3 of the utility model
Face, chip 1 are located on printed circuit board 2.
As shown in Fig. 2, the fixer for heat radiator 3 of the utility model, which includes pedestal 33, institute
Pedestal 33 is stated equipped with elastic slice 31, the both ends of the elastic slice 31 are respectively engaged with the both ends of pedestal 33, and 31 center of elastic slice is set
It is equipped with fixing screwed hole 35 and the standing screw 36 with the fixing screwed hole 35 cooperation, the standing screw 36 is by the bullet
Piece 31 is fixed on radiator 4, and the both ends of the pedestal 33 further respectively have the lifting structure 32 for limiting 31 both ends of elastic slice,
And to the bit-stopping structure 34 that the lifting structure 32 is limited.
31 both ends of the present embodiment elastic slice are in concave, but are also not necessarily limited to concave, such as " L " type can also.33 both ends of pedestal are equipped with
Column 38,31 both ends of elastic slice are connected on the column 38 at 33 both ends of pedestal.
The lifting structure 32 of the present embodiment is a cylindrical elevating lever, and 33 both ends of pedestal are equipped with for installing cylindrical lifting
The card slot 37 of bar, elevating lever can move up and down in card slot 37.Elevating lever is pressed on the end of elastic slice 31, for limiting elastic slice
