Example Embodiment

[0015] Please refer to figure 1 The preferred embodiment of the heat dissipation module of the present invention includes a heat sink 20, a motherboard 50 and a number of locking devices 100.

[0016] The heat sink 20 includes a bottom plate 22 and a plurality of fins 24 extending upward from the bottom plate 22. The bottom plate 22 has a through hole 26 at four corners.

[0017] The main board 50 defines a plurality of fixing holes 52 corresponding to the through holes 26 of the heat sink 20.

[0018] Please refer to figure 2 Each locking device 100 includes a buckle bar 10, an elastic element 30 set on the buckle bar 10, and a nut 40.

[0019] The tie rod 10 includes a cylinder 12, a threaded portion 14 formed at one end of the cylinder 12, and a buckle portion 16 extending from the other end of the cylinder 12. The buckle 16 includes two blocking hooks 161 spaced apart. Each blocking hook 161 includes a blocking surface 1611 facing the threaded portion 14 and an inclined surface...

Abstract

The invention provides a heat radiating module which comprises a locking device, a heat radiator and a mainboard. The heat radiator comprises a baseboard, a penetrating hole is formed in the baseboard, a fixing hole is formed in the mainboard, the locking device comprises a buckling rod, an elastic element and a nut, the buckling rod comprises a column, a threaded portion formed by extending from the top end of the column, and a buckling portion formed by extending from the bottom of the column, the buckling portion comprises two retaining hooks which are opposite, the nut comprises a stud, a threaded hole is formed in one end of the stud, the elastic element sleeves the column, an internal thread of the nut and the threaded portion of the buckling rod are in screwed fit, the buckling portion of the buckling rod penetrates the penetrating hole of the baseboard and the fixing hole of the mainboard, the retaining hooks are retained to the mainboard, and the top end of the elastic element is connected to the stud of the nut in an abutted manner while the bottom end of the same is connected to the baseboard of the heat radiator in an abutted manner. The invention further provides the locking device. Compared with the prior art, the locking device of the heat radiating module has the advantage that the nut is rotated to change extending and contracting length of the elastic element so as to change buckling force.

Description

technical field [0001] The invention relates to a heat dissipation module and a locking device thereof. Background technique [0002] In the existing heat sinks, they are often locked to the main board by screws. Since the fastening force is fixed, it will cause poor contact between the heat dissipation device and the electronic components of the main board, resulting in poor heat dissipation. Contents of the invention [0003] It is necessary to provide a locking device with adjustable fastening force and a cooling module using the locking device. [0004] A locking device, comprising a buckle rod, an elastic element and a nut, the buckle rod includes a cylinder, a threaded part formed at one end of the cylinder and a buckle part formed at the other end of the cylinder, The nut is provided with a threaded hole that can match the threaded part of the buckle rod, and the elastic element is sleeved on the cylinder of the buckle rod and located between the nut and the buckle...
