Abstract

The utility model relates to a computer heat sink, in particular to radiator that can effectively improve computer heat exchanger. This radiator includes the central pedestal of D shape and the curved curved's of several heat radiation fins, and heat radiation fins connects on the external circular arc surfaces of central pedestal with the mode equidistance of anticlockwise range. Through the quantity of optimizing heat radiation fins, and heat radiation fins's crowded shape length -width ratio, having increased heat radiating area, increased the radiating rate, the at utmost has guaranteed that little electron device is thermal lost as early as possible, has prolonged little electron device's life.

Description

A kind of computer radiator

Technical field

The utility model relates to a kind of heating radiator, and particularly one effectively can improve the permutable heating radiator of craze for computer.

Background technology

Good thermal diffusivity is the prerequisite ensureing computer main board steady operation.Existing heating radiator is with manufactured by the mode of aluminum extruded shaping mostly, and when entire area is constant, the quantity of fin is more, and area of dissipation is larger, and its radiating effect is better.But extruding-out process has its certain crowded shape length breadth ratio restriction, thus the radial fin increased can cause cannot the risk of extrusion molding, and crowded shape burn failure or reduced lifetime may be caused.

Utility model content

For solving the problems of the technologies described above, the purpose of this utility model is the computer radiator providing a kind of excellent in heat dissipation effect, and it when increasing crowded shape length breadth ratio not significantly, can increase area of dissipation.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of computer radiator, comprise the central pedestal of D shape and several forniciform radiating fin, described radiating fin is equidistantly connected on the exterior arc surface of described central pedestal in the mode of arranged counterclockwise.

Preferably, the outermost end points of all described radiating fins is all positioned in same circle.

Preferably, the center of circle of described circle overlaps with the exterior arc surface center of circle of described central pedestal.

Preferably, described radiating fin has identical curved shape.

Preferably, described radiating fin has identical specific curvature.

Preferably, described radiating fin and central pedestal one aluminium extruded are shaped.

Preferably, also comprise a base, described base is connected to the bottom of described central pedestal, and this heating radiator is connected to microelectronic device by this base.

Preferably, also comprise a support, described support is connected to the bottom of described base, and this heating radiator is connected to microelectronic device by support.

Compared with prior art, the utility model has the advantages that: by optimizing the quantity of radiating fin, and the crowded shape length breadth ratio of radiating fin, add area of dissipation, add radiating rate, at utmost ensure that scattering and disappearing as early as possible of microelectronic device heat, extend the serviceable life of microelectronic device.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.

Fig. 1 is the vertical view of a kind of computer radiator disclosed in the utility model embodiment one;

Fig. 2 is the side view of a kind of computer radiator disclosed in the utility model embodiment two.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

Embodiment one

A kind of computer radiator as shown in Figure 1, comprise central pedestal 11 and 28 forniciform radiating fins 12 of D shape, all radiating fins 12 have identical curved shape, and have identical specific curvature.Radiating fin 12 is equidistantly connected on the exterior arc surface of central pedestal 11 in the mode of arranged counterclockwise.The diameter of the exterior arc surface of central authorities' pedestal 11 is 85mm, and its length faced directly is 13.5mm.The outermost end points of all radiating fins 12 is all positioned in same circle, and the diameter of this circle is 50mm, and its center of circle overlaps with the exterior arc surface center of circle of central pedestal 11.

Radiating fin 12 is shaped with central pedestal 11 one aluminium extruded.Because central pedestal 11 is solid, when it is connected with microelectronic device, adds heat conduction efficiency between the two, can dispel the heat to microelectronic device faster.

Embodiment two

As shown in Figure 2, the present embodiment and embodiment one unlike, this heating radiator also comprises a base 13 and support 14, and base is connected to the bottom of central pedestal 11, and support is connected to the bottom of base, and this heating radiator is connected on microelectronic device by support.

In sum, the utility model has the advantages that: by optimizing the quantity of radiating fin, and the crowded shape length breadth ratio of radiating fin, add area of dissipation, add radiating rate, at utmost ensure that scattering and disappearing as early as possible of microelectronic device heat, extend the serviceable life of microelectronic device.

To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
