Abstract

The invention discloses a heat sink which comprises a heat radiator, a heat pipe, an absorber plate and a fastener. The two ends of the heat pipe are respectively connected with the absorber plate and the heat radiator; the fastener comprises a buckle slab and two fastening parts; the buckle slab comprises a pressing and fixing part in the middle and two end parts positioned at the two sides of the pressing and fixing part; the two fastening parts are respectively arranged at the two end parts of the buckle slab; a mounting hole is arranged at each end part of the buckle slab; a plurality of baffle pieces are arranged at the periphery of the mounting hole towards the center of the mounting hole in a protruding manner; a clamping trough is arranged in the middle of each fastening part; the plurality of baffle pieces are clamped in the clamping troughs to prevent the fastening parts from dropping from the mounting holes; and the pressing and fixing part of the fastener props the end part of the heat pipe onto the absorber plate.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a buckle for fixing the heat dissipation device. Background technique [0002] With the rapid development of the computer industry, more and more heat is generated by heat-generating electronic components such as micro-processing chips. The component is used for heat dissipation, and the fixing structure usually used is a spring screw. For example, a number of through holes are opened at the position where the heat sink needs to be fixed. The diameter of the through hole is larger than the outer diameter of the thread of the spring screw and smaller than the outer diameter of the spring. Through the through hole, and locked in the corresponding threaded hole on the circuit board. In order to facilitate transportation, often after the spring screw and the radiator are assembled together, a buckle needs to be set on the screw to prevent the spring screw from falling off. However, this...
