Problems solved by technology

Since the above-mentioned structure is held against the bottom surface of the circuit board by the barb of the fastener, when disassembling, it is necessary to use an external tool to deform and close the barb of the fastener to withdraw from the circuit board and the radiator, which is cumbersome and time-consuming, or use a tool to disassemble the circuit board. The barb is partially cut off, and the fastener is discarded, which is not conducive to resource reuse, so this kind of fastening structure needs to be further improved

Embodiment Construction

[0016] see figure 2 , the electronic device in some embodiments of the present invention includes a carrier board 300 and a heat sink mounted on the carrier board 300 . The cooling device is used to dissipate the heat generated by an electronic component 400 (for example, a computer CPU) mounted on the carrier board 300 . The heat dissipation device includes a heat sink 200 and two fasteners 100 for fixing the heat sink 200 on the electronic component 400 .

[0017] Please also see image 3 , each of the above-mentioned fasteners 100 includes a fastener 110 and an elastic element mounted on the fastener 110 . In some embodiments, the elastic element is a spring 120 . The fastener 110 is integrally made of plastic material or other materials, and includes a connecting rod 114 , an operating portion 112 at the top of the connecting rod 114 , and a fastening portion 116 at the bottom of the connecting rod 114 . The elastic element is sheathed on the connecting rod 114 .

Abstract

The invention discloses a buckle, which is used for fixing a radiator to a bearing plate and comprises a connecting rod, an elastic element sleeved on the connecting rod and a buckling part positioned on the end part of the connecting rod, wherein the buckling part comprises a stopping part and at least one positioning part; and the positioning part is extended away from the stopping part towards one side of the connecting rod. Compared with the prior art, the buckle can realize the arrangement and disassembly of the radiator only by rotating the connecting rod without using any external tool and being damaged by a tool. The invention also provides a radiation device using the buckle, and an electronic device.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device for electronic components. Background technique [0002] With the improvement of computing speed and power consumption of the electronic components inside the electronic device, the corresponding heat generated will also increase sharply. In order to make the electronic components operate at normal operating temperature, it is usually necessary to attach a heat sink on the surface of the electronic components. The heat sink is used to discharge the heat generated by the electronic components in time, and in order to make the heat sink and the electronic components closely fit to achieve a good heat dissipation effect, various heat sink fastening structures are adopted. [0003] At present, the common radiator fastening structure is as follows: figure 1 As shown, the fastening structure includes two fasteners 10 for fixing a heat sink 20 to an electronic comp...
