Description
[technical field]
The utility model is meant a kind of heat abstractor of auxiliary electron element radiating especially about a kind of heat abstractor.
[background technology]
Continuous progress along with integrated circuit technique, the electronic component speed of service constantly promotes, the heat of its generation also increases thereupon, if discharging, untimely heat with its generation will cause its temperature constantly to raise, and then have a strong impact on the performance of its operation, for guaranteeing that electronic component can normally move, usually at its mounted on surface one heat abstractor so that heat is distributed apace.
In the prior art, the heat abstractor that is used for electronic element radiating has multiple, as the exposure of No. the 527078th, TaiWan, China patent announcement just is wherein a kind of, it has an aluminium extruded type radiator and an elastomer, this radiator is bent with buckle ear in the radiating fin of central authorities to both sides, and upwards protruded out lug in root edge, buckle ear and lug form limiting section, this elastomer is the linear fastener that is formed by wire one bending, its central authorities have a support division that protrudes, and extend a horizontal base in the both sides of support division, the outward-dipping cantilever that is bent with that makes progress continues, this cantilevered distal end extends a buckling parts, this linearity fastener by being fastened on limiting section on the radiating fin and accurate in locating on radiator, utilize the hook between buckling parts and associated component or structure (the side projection of the connector that plugs as electronic component, or the hole on the circuit board) again and be tight against radiator, and radiator is closely adhered to the electronic component end face.Limiting section is set on the radiating fin of this heat abstractor makes fastener be positioned at the pre-assembling of realization on the radiator on the one hand, transportation is easy to carry, make the fastener accurate in locating on the other hand on radiator, in assembling process or during end-state, guarantee that radiator and fastener are in correct relative between the two.
Lifting along with electronic component integrated level and operating frequency, its heat that distributes also increases thereupon, because the aluminium extruded type radiator can not reach higher radiating fin density and depth-width ratio, the unit volume area of dissipation is limited, and can't satisfy the heat radiation requirement, industry radiator commonly used is to be attached on the pedestal by sheet metal machine-shaping in advance by radiating fin to form again at present, the lamellar body of the radiating fin of this kind radiator is thinner, on it limiting section that cooperates with linear fastener can't be set, and if also be easy to make radiating fin to produce distortion, so need another heat abstractor to satisfy the needs of electronic element radiating by the radiating fin location.
[summary of the invention]
The heat abstractor that provides a kind of fastener can be accurately positioned on the radiator and be not subjected to the radiating fin effects limit of radiator is provided the purpose of this utility model.
The purpose of this utility model is achieved through the following technical solutions:
The utility model heat abstractor, comprise a radiator and at least one fastener, this radiator comprises a substrate and the some radiating fins that are arranged on this substrate, this radiator base plate is provided with at least one fixing hole, this fastener comprises a buckling piece and at least one fixture, this buckling piece is formed by wire one bending, it comprises a pressure section and two arms that extended by the end of this pressure section, this fixture is positioned in the fixing hole of radiator base plate, it is pressed against the pressure section top, thereby fastener is positioned on the radiator.
The utility model heat abstractor is positioned at fastener on the radiator with the cooperating of fixing hole of radiator accurately by the fixture of fastener, also can conveniently realize the location even the radiating fin of radiator is thin, and not be subjected to the influence of radiating fin factor.
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
