Problems solved by technology

Because the sheet-shaped ring of the pre-assembled fastening structure is easy to fall off from the screw, the fastening structure will be detached from the radiator during transportation, which will bring adverse effects to producers and consumers
In addition, the assembly of the flake ring requires the use of specific fixtures, which is not conducive to disassembly and installation

Embodiment Construction

[0016] see figure 1 and figure 2 An embodiment of the heat dissipation device of the present invention includes a heat sink set 30 , a base plate 10 carrying the heat sink set 30 , and a fastening structure 20 disposed on the base plate 10 .

[0017] The base plate 10 includes a body portion 11 and four lugs 12 extending obliquely outward from the four top corners of the body portion 11. The body portion 11 is in a square shape, and the bottom surface of the body portion 11 is attached to the heat conduction element 40. The top surface of the main body 11 is connected to the heat sink set 30; the four lugs 12 are roughly elongated and each lug 12 is provided with a perforation 13, and the perforation 13 is circular to match the buckle structure 20 penetration.

[0018] The heat sink set 30 is disposed on the body portion 11 of the substrate 10 and is formed by a plurality of heat sinks 31 for dissipating heat from the heat conducting element 40 . The heat dissipation devic...

Abstract

The invention relates to a fastening structure for fixing a heat dissipation device, which comprises a fixing element as well as an elastic element and a fastener which are sleeved at the fixing element, wherein the fixing element comprises an operating part arranged at one end and a fixing part arranged at the other opposite end, the fixing part is provided with a buckle, the elastic element is arranged between the buckle and the fastener, several buckles extend out from the operating part, the fastener is provided with a through hole for the buckles to pass through and a retaining slot for retaining the buckles, the fastening structure is compact and stable in structure, convenient in installation and dismounting, and has no risk of falling from the heat dissipation device in the transportation process. The invention also relates to a heat dissipation device providing with the fastening structure.

Description

technical field [0001] The invention relates to a heat dissipation device and its fastening structure, in particular to a fastening structure for fixing the heat dissipation device to components such as circuit boards. Background technique [0002] With the improvement of the computing speed and power consumption of the chip inside the electronic device, the corresponding heat generated will also increase sharply. In order to make the chip run at normal operating temperature, it is usually necessary to attach a heat sink on the surface of the chip in time. To dissipate the heat generated by the chip, and in order to make the heat sink and the chip closely fit to achieve a good heat dissipation effect, various heat sink fastening structures are adopted in the industry. [0003] The traditional fastening structure of the radiator includes a screw, a spring sleeved on the screw and a sheet-shaped ring. The middle part of the sheet-shaped ring is a deformable elastic piece. The ...
