Abstract

The utility model relates to a radiator, which is provided with a heat radiating body. The heat radiating body comprises a base and a plurality of heat radiating fins, wherein, the bottom face of the base is extended in a convex way and is provided with a contacting part, and the top face is extended and provided with a central body; the central body is provided with a bottom part and a top part, wherein, the area of the bottom part is larger than the area of the top part, and the top part and the bottom part are connected into integration by an inner concave arc diversion face; the heat radiating fins are formed from the arc diversion face which is extended outwards in a radial shape, and the thickness of the heat radiating fins is gradually thickened toward the direction away from the central body; the heat radiating fins are all higher than the top part of the central body. A cavity is formed from the heat radiating fins and the top part of the central body, and the cavity is used for containing a fan.

Description

Radiator

[technical field]

The utility model is about a kind of radiator, refers in particular to a kind of airflow smooth, radiator that radiating effect is good.

[background technology]

Electronic component the time can produce a large amount of heats in operation, if untimely heat is discharged, and the stability when influence electronic component and move.For this reason, industry is installed a radiator at electronical elements surface usually, is used for heat is discharged as early as possible.

Existing radiator generally includes a radiator and and is installed in fan on this radiator.Wherein this radiator is provided with a pedestal, and vertical extent has some fin on this pedestal; And this fan is installed on the fin of this radiator, vertically is blown into cold airflow to the radiator pedestal by fan and assists the radiator heat radiation.Yet, the cold airflow of this radiator is vertically to enter in the radiator, after the cold airflow contact radiator base bottom surface again to very slow during from fan fin diffusion far away on the radiator, air-flow is also smooth and easy inadequately, feasiblely almost do not bring into play thermolysis, thereby reduced the radiating effect of entire radiator from fan fin far away; In addition, because radiator can amass one deck dust on pedestal of its radiator and the fin after use a period of time inevitably, when the pedestal of the vertical radiator of cold airflow is blown into, be difficult to dust is taken away, and this also can reduce the radiating effect of radiator gradually.Correlation technique can be with reference to No. the 86215809th, Taiwan patent application.

[summary of the invention]

The purpose of this utility model is to provide a kind of tool arc guide face, radiator that radiating effect is good.

The purpose of this utility model is achieved through the following technical solutions: the utility model radiator comprises a radiator and a fan.This radiator has a pedestal and some fin.This base bottom surface has protruded out a contact site, and end face has extended a centerbody.This centerbody is provided with a bottom and a top, and wherein this bottom area is greater than topside area, and is that arc guide face by an indent links together between this top and bottom.These fin are outwards to be radial extension by this arc guide face to form, and towards away from centerbody direction progressive additive, these fin all are higher than the top of this centerbody.These fin and this centerbody top surround an inner chamber, and this inner chamber is to be used for ccontaining this fan in wherein.

Owing to adopted technique scheme, the utility model radiator in use, the cold airflow that fan rotation produces is flowed through between each fin swimmingly along the guide face of the pedestal of radiator, not only can realize and fully the contacting of each fin, and blown away the dust that reaches between each fin on the pedestal, realize preferable radiating effect.

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

[description of drawings]

Fig. 1 is the stereogram of the radiator of the utility model radiator.

Fig. 2 is that the solid of the radiator of the utility model radiator is partly cutd open figure.

Fig. 3 is the three-dimensional combination figure of the utility model radiator.

[embodiment]

Please refer to Fig. 3, the utility model radiator 1 is to be fixed on the circuit board (figure does not show), is used for distributing the heat that electronic component on the circuit board (figure does not show) produces, and this radiator 1 comprises a radiator 10 and a fan 20.

Please together referring to figs. 1 to Fig. 2, this radiator 10 comprises a pedestal 110 and some fin 120.

These pedestal 110 bottom surfaces protrude out a contact site 111 that fits with electronic component, and its end face has then extended a centerbody 112; The both sides of this pedestal 110 are respectively equipped with a through hole 117, are used for wearing for screw (figure does not show), and by screw entire radiator 1 are fixed on the circuit board.This centerbody 112 comprises a bottom 113 and a top 114, and wherein these bottom 113 areas are greater than the area at top 114, and this

bottom

113 and 114 at top are that arc guide face 115 by an indent links together.

These fin 120 are outwards to be that radial extension forms and towards the centerbody 112 direction progressive additives away from this pedestal 110, these fin 120 all are higher than the top 114 of this centerbody 112 by this arc guide face 115.These fin 120 surround an inner chamber 116 with these centerbody 112 tops 114, and this inner chamber 116 is to be used for ccontaining this fan 20 in wherein.

During use, flow through swimmingly along the guide face 115 of the pedestal 110 of radiator 10 120 of each fin of the cold airflow that fan 20 rotation produces, not only can realize and fully the contacting of each fin 120, and blow away dust on 120 of each fin and the centerbody 112.
