Fastener and heat radiating device assembly using the same

Abstract

The invention relates to a radiator combination, comprising a radiator and a fastener. The radiator comprises a soleplate and a plurality of radiating fins arranged on the soleplate; the fastener comprises a butting part butting against the soleplate; the two ends of the butting part respectively bend and extend to form bending parts; the tail end of each bending part further extends to form a fastening arm; an extension part is connected between the bending part of the fastener and each fastening arm; where the extension part is parallel to the butting part, the fastening arm is vertical to the extension part; and the two opposite sides of the bending part butting against the soleplate prevent the fastener from horizontally moving relatively to the radiator. The fastener in the radiator combination is provided with bending parts butting against the two sides of the soleplate of the radiator so as to prevent the fastener from horizontally moving along the two sides of the soleplate of the radiator, further to keep the stable fastening force of the fastener and guarantee the radiation effect of the radiator.

Description

technical field [0001] The invention relates to a buckle and a heat dissipation device combination using the buckle, in particular to a buckle with good fastening effect and a heat dissipation device combination using the buckle. Background technique [0002] The commonly used combination of cooling devices for cooling electronic components mainly includes a radiator and a fastener. The hooks between the side bumps or the holes provided on the circuit board are tightly pressed against the heat sink, so that the heat sink is closely attached to the electronic components. Wherein, the buckle is formed by bending an elastic metal rod. In this design, the metal rod body has a horizontal pressing portion and arm portions that are bent and extended vertically from both ends of the pressing portion, and the pressing portion is pressed against the top of the radiator. A hook portion is extended from the end of each arm portion, and the heat sink is closely attached to the top surf...

Problems solved by technology

[0003] Although this kind of fastening method can better fix the radiator in the vertical direction through the pressing of the pressing part of the fastener, after the fastening, the fastener and the radiator will not move relative to each other in the vertical direction, but the horizontal Since there is no specific fixing force in the direction, under the influence of the external environment, the fastener will move in the horizontal direction relative to the heat sink, which will affect the clamping force of the fastener, and then affect the close contact between the heat sink and the electronic components. degree, which has adverse consequences on the heat dissipation of electronic components
