Abstract

The utility model relates to a heat radiating fin, which comprises a heat radiating plate contacted with a component and a plurality of heat radiating fins formed in the mode that the heat radiating plate is extended outwards, wherein, the middle part of the heat radiating plate is thick, edge is thin, so the outer end part of the heat radiating fins at the middle part is high, and the outer end part of the heat radiating fins at edge is low. The heat transferring process is similar to the solar radiation process according to heat radiating principle, a heat radiating surface adopts the design of low edge and high middle part to increase heat capacity, so heat radiating effect is optimum. Gaps between the heat radiating fins and a fan are enlarged, airflow friction is reduced, and noise is reduced; the weight of integral heat radiating fins is reduced, and material is saved.

Description

Fin

Technical field

The utility model relates to a kind of heat abstractor, particularly a kind of fin of being made up of a plurality of radiating fins.

Background technology

The electronic devices and components of computer-internal the time can produce heat usually in work, and the components and parts temperature is raise, and can exert an influence to the operate as normal of components and parts.Temperature when wherein, central processing unit is worked is high especially.Therefore, heat abstractor must be installed to guarantee components and parts operate as normal under suitable temperature.

The present employed overwhelming majority's heat abstractor all adopts fin as thermal component, the end of existing fin is that the heat radiation of an entity is dull and stereotyped and contact with components and parts, the heat radiation flat board extends outward a plurality of radiating fins, the outer end of radiating fin is positioned on the plane, and fan is equipped with in its outer end, the narrow gaps between radiating fin and the fan, and windage is big, the air-flow friction is big, and noise is big.

Summary of the invention

The purpose of this utility model provides a kind of utilization heat radiation mechanism, good heat dissipation effect, the fin that noise is little.

To achieve the above object, the technical solution of the utility model is as follows:

A kind of fin, comprise a plurality of radiating fins that the heating panel that contacts with components and parts and heating panel stretch out and form, the also corresponding outer end for the radiating fin at the height edge, outer end of the radiating fin at middle part of thick, the thin edge in the middle part of described heating panel, radiating fin is low.

In preferred version of the present utility model, the end face that described heating panel contacts with components and parts is the plane, and another end face that extends to form radiating fin is that low middle part, edge is high, the outer end correspondence of radiating fin also be height, edge low at middle part.

Described radiating fin is arranged in parallel.

The end face that described heating panel extends to form radiating fin is the low middle high cambered surfaces in two ends.

The end face that described heating panel extends to form radiating fin is a sphere.

The end face that described heating panel extends to form radiating fin is that two high outside low clinoplains in middle part piece together.

The middle part that described heating panel extends to form the end face of radiating fin is provided with a plane that is higher than the end.

The end face that described heating panel contacts with components and parts is a middle part low edge height, the outer end correspondence of radiating fin also be height, edge low at middle part.

Described radiating fin is arranged in parallel.

The middle part of the end face that described heating panel contacts with components and parts is provided with a plane that is higher than the end.

According to heat radiation mechanism, heat transfer process is similar to the solar radiation process, and radiating surface adopts the high design in low middle part of above-mentioned edge, increases thermal capacity, and radiating effect is ideal; It is big that gap between radiating fin and the fan becomes, and the air-flow friction diminishes, and noise reduces; The weight saving of integral heat sink sheet, and saved material.
