A kind of heat radiation fin structure and radiator thereof

Technical field

The utility model relates to a kind of heat radiation fin structure and radiator thereof, refers to the structure that a kind of radiating fin combines with heat pipe especially.

Background technology

Along with industry constantly develops, removing of cooling or heat is always the big obstacle that electronic industry develops.Along with the raising and the multi-functional application of dynamical requirement, degree of integration, also face big challenge for the requirement of dispelling the heat, so just become the major subjects of electronics industry for the research and development of heat transfer efficient.

Radiating fin (Heat Sink) is used in heat dissipation with assembly or system usually among atmosphere; And under the lower situation of thermal resistance, show that then described fin has higher radiating efficiency.In general, thermal resistance is made of the diffusion thermal resistance of fin inside and the thermal-convection resistance between described fin surface and the atmospheric environment; On using, the material of high conductance such as copper, aluminium etc. often are used to make fin to reduce the diffusion thermal resistance; Yet thermal-convection resistance has limited the usefulness of fin, makes it can't reach the heat radiation requirement of electronic building brick of new generation.

Existing market all is conceived to more efficient cooling mechanism, and the heat pipe (Heat pipe) that proposes to have high heat conduction efficiency successively makes up with radiator fins, with effective heat dissipation problem that solves present stage.

The mode that present heat pipe combines with radiator has several, first heat pipe is connected with the open-work on the radiator fins is friction tight, but this combination, when heat pipe runs through open-work, cause heat pipe and fin to produce heat pipe surface scratch or fin distortion easily because of wearing to pull, when serious even cause open-work to break, therefore the yield of this manufacturing is lower.

It two is that heat pipe is adopted in the loose fit mode with the open-work on the radiating fin and combined, between heat pipe and its radiating fin, utilize heat-conducting glue or tin cream to plug the gap, adopt this mode, need on radiating fin, to offer groove and be communicated with open-work, and in groove, fill heat-conducting glue or tin cream, utilize heating to make heat-conducting glue or tin cream be melted into the aqueous solid shape that is cooled to again again after earlier heat pipe being run through open-work, and then be located in heat pipe and the radiating fin, but this combination fabrication steps is many, and easily cause unnecessary heat-conducting glue or tin cream to drip to be exposed to the increase of the not good and thermal impedance that causes visual appearance on the fin, and longer from the time that is fabricated onto the product of finishing, therefore the efficient of making is not high.

The utility model content

The utility model is that mainly the outer surface that provides a kind of extension on a radiating fin body to form a plurality of recesses and protuberance and described heat pipe forms interference, and then closely be strapped in the outer surface of described heat pipe, described body is combined closely with described heat pipe.
