Abstract

A fixing device for a radiator is used for fixing the radiator which is arranged on a base board and provided with two through holes. The fixing device comprises a printed circuit board (PCB), two locking members and two clamping blocks, wherein the PCB is provided with two penetrating holes, the two locking members penetrate through the through holes of the radiator respectively, each locking member comprises two clamping pins which penetrate through one penetrating hole and are clamped at the bottom of the PCB and arranged at an interval, one clamping block is put between two clamping pins of each locking member and capable of preventing the two clamping pins from falling off from corresponding penetrating holes of the PCB due to deformation, and therefore the radiator is enabled to be firmly fixed on the PCB.

Description

technical field [0001] The invention relates to a radiator fixing device. Background technique [0002] In the prior art, the heat sink is generally fixed on a circuit board by a plurality of locking pieces with two locking feet. However, the legs of these fasteners are often deformed, which can cause the heat sink to loosen or come off the circuit board. Contents of the invention [0003] In view of the above, it is necessary to provide a fixing device capable of stably fixing the radiator. [0004] A heat sink fixing device is used to fix a heat sink with two through holes on a base plate, the heat sink fixing device includes a circuit board with two through holes, two locking pieces respectively passing through the through holes of the heat sink and Two clamping pieces, each locking member includes two spaced clamping feet that pass through a through hole of the circuit board and are clamped on the bottom of the circuit board, and a clamping block is sandwiched betwee...
