Embodiment Construction

[0013] Refer to figure 1 , Which is an exploded view of an embodiment of the heat sink of the present invention. The heat dissipation device includes a radiator 10, a fan 30, and two fasteners 50 clamped on the outside of the top of the radiator 10, and the two fasteners 50 are used to fix the fan 30 on the top surface of the radiator 10. The fan 30 is substantially square and includes an outer frame with an upper plate and a lower plate 32 for clamping by the fastener 50.

[0014] The heat sink 10 includes a base 11 in contact with electronic components (not shown), and a plurality of heat dissipation fins 13 vertically extending from the top surface of the base 11 and spaced in parallel. Also see Figure 4 Two sides of the upper end of each heat dissipation fin 13 are respectively provided with grooves, and each groove includes a first accommodating portion 131 and a second accommodating portion 135 communicating with the first accommodating portion 131.

[0015] The first accom...

Abstract

The invention relates to a heat-dissipation device which comprises a radiator provided with a plurality of heat-dissipation fins, a fan and two buckle appliances clamped at the two opposite sides of the heat-dissipation fins for fixing the fan. The two opposite sides of the heat-dissipation fins are provided with grooves; each buckle appliance comprises a flashboard inserted into the adjacent groove and a side board arranged at the external side of the heat-dissipation fins for connecting the flashboard, wherein, each buckle appliance comprises an elastic spacer which extends from either the flashboard or the side board and is propped in the grooves of the heat-dissipation fins to fix each buckle appliance on the radiator; an elastic buckle slab is formed at the top of the side board and is propped and pressed on the fan. Compared with the prior art, the heat-dissipation device can realize the cooperation of the radiator and the fan with the mutual functioning of the flashboard, the side board and the buckle slab without relying on any tool, and the heat-dissipation device has simple structure and convenient assembling and disassembling.

Description

Technical field [0001] The invention relates to a heat dissipation device and a fastener thereof, in particular to a heat dissipation device and a fastener thereof with simple structure and convenient disassembly and assembly. Background technique [0002] As we all know, electronic components such as the central processing unit generate a lot of heat during operation. In order to prevent the temperature of the electronic component from increasing due to the accumulation of heat and thereby causing its operation to become unstable, the electronic component usually needs to be equipped with a heat sink to assist its heat dissipation. [0003] Generally, the above-mentioned heat dissipation device includes a heat sink having a bottom plate for contacting electronic components to absorb heat and a plurality of heat dissipation fins arranged on the bottom plate. In order to improve the heat dissipation capacity of the radiator, the heat dissipation device further includes a fan that ...
