Abstract

The utility model relates to radiator structures, in particular to a combined structure of a radiator body and fins. The radiator fin embedded structure comprises the radiator body and the fins arranged on the surface of the radiator body, a plurality of fin embedded grooves are arranged in the surface of the radiator body, and the fins are embedded into the fin embedded grooves. When the radiator fin embedded structure is used, the fins and the radiator body can be manufactured independently, whole forming in the prior art is not needed, and therefore thicknesses of the fins can be reduced greatly, more fins can be installed in unit area for radiating, and radiating capacity of a radiator whole is effectively improved.

Description

The heat radiator fin embedded structure

Technical field

The utility model relates to heat spreader structures, especially the integrated structure of heat sink and fin.

Background technology

Radiator generally is used for the heat radiation of electronic equipment, heat transmission equipment, power-equipment, the radiating effect of radiator is subject to the impact of the factors such as material, structure, most radiator is that aluminum material is made on the market now, under identical material condition, the structure of radiator becomes the key factor that determines the radiator heat-dissipation effect.

Existing radiator generally comprises the matrix that contacts with thermal source and the fin be located on the matrix forms, the matrix of existing radiator and fin are generally the extruding integral molding, be subject to the restriction of manufacturing process, the thickness of fin is generally larger, when making thinner fin, is not easy moulding in extrusion process, manufacture difficulty is larger, and the thickness of fin is larger, and the number of fins on the unit's of causing matrix area is less, the radiating effect that impact is whole.

Summary of the invention

The utility model provides a kind of heatsink fins chip architecture that comprises more fin on the heat sink of the same area surface, improves radiating effect that makes.

To achieve these goals, the utility model adopts following technical scheme:

It comprises heat sink and the fin of being located at the heat sink surface, and described heat sink surface is provided with a plurality of fin embedded grooves, and described fin is embedded in the described fin embedded groove.

In the said structure, the opening of described fin embedded groove is less than internal diameter, and described fin root comprises an Embedded Division that adapts with fin embedded groove shape.

In the said structure, be intervally distributed with a plurality of radiating ribs that protrude from fin surface and extend along fin on the described fin.

In the said structure, be provided with in the described heat sink along the passage that connects in the radiator, be provided with a heat pipe or cup-shaped metalwork or metal decking in the described passage.

Owing to adopted said structure, after the utility model heat radiator fin embedded structure uses, fin and heat sink can be made respectively, need not to adopt existing global formation, so the thickness of fin can significantly reduce, thereby dispel the heat so that more fin can be installed on the unit are, effectively improved the heat-sinking capability of radiator integral.

The specific embodiment

Figure and 1-are shown in Figure 3, the heat radiator fin embedded structure of present embodiment comprises heat sink 1 and is located at the fin 2 on heat sink 1 surface, described heat sink 1 surface is provided with a plurality of fin 2 embedded grooves 11, and described fin 2 is embedded in the described fin embedded groove 11.Present embodiment is take the column radiator matrix as example, be not limited to column radiator during practical application, for example also can for heat sink block, strip, on the plane that fin is mounted thereon, equally also play the purpose of improving extrusion forming process by assembling.

After making fin 2 be embedded into fin embedded groove 11, can realize fixing, need not other security measure, in the present embodiment, the opening of described fin embedded groove 11 is less than internal diameter, and described fin 2 roots comprise an Embedded Division 21 that adapts with fin embedded groove 11 shapes.

Because the fin of processing is thinner separately, for the intensity that increases fin and the trend of disturbing hot-fluid, improve radiating effect, be intervally distributed with a plurality of radiating ribs 22 that protrude from fin surface and extend along fin on the described fin.Two of fin 2 ends are provided with radiating ribs 22 in the present embodiment, and radiating ribs can be used as simultaneously Embedded Division 21 and uses, and increases the surface area that radiating ribs has also increased later on fin, has further improved radiating effect.

In the present embodiment, when the radiating requirements of thermal source not simultaneously, heat sink 1 can be made as required part and improve, when heat dissipation capacity is little, heat sink 1 can be made for a block of metal, when heat radiation is had relatively high expectations, can be provided with in described heat sink 1 along the passage 12 that connects in the radiator, be provided with a cup-shaped metalwork or heat pipe or metal decking in the described passage 12, the end face by heat pipe or cup-shaped metalwork or metal decking contact thermal source.

The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
