Abstract

A fin-type air-cooled radiator is characterized in that: a plurality of fins are arranged above the heat guide base plate and is radiating from the inner to the outside to form the spaced arrangement; the middle part of the fin is sunken downward, a fan is arranged at the concave. The wind is pressing down transmitted from the inner concave, to make each fin radiates from the place near the center of the base plate, which is benefit for absorbing the heat from the CPU inner core; the fin radiating arranged can form the air flowing paths which are communicate to the four sides, making the wind of the fan be discharged from the inside to the outside, thus effectively improve the heat dispersing effects. The utility model has the advantages that: has good heat dispersing effect and can effectively ensure that the CPU work for a long time.

Description

The fin-type air-cooled radiator

The utility model relates to a kind of fin-type air-cooled radiator that CPU dispels the heat in the computer that is mainly used in.

Along with fast development of computer technology, the integrated transistor of master chip in the computer gets more and more, the heat that sends is also increasing, and the radiator that uses at present, basically be to be the mountain font, can only about or cross ventilation, because circular fan is only more intense to middle those several fin blast, fin the closer to both sides is accepted more little from the blast of fan, thereby its radiating effect is poor, wants to increase radiating effect, and a kind of method is the power that adds big fan, strengthen rotating speed, but but this kind scheme has increased the noise of fan.Another kind method is to strengthen heat radiation or increase fin, and how many its radiating effects but do not increase.

The purpose of this utility model just provides a kind of fin-type air-cooled radiator of good heat dissipation effect.

Solution of the present utility model is such: the radiating fin of conductive sole plate top is a multi-disc, and from inside to outside the width of cloth is penetrated to form and is spaced.Make each sheet radiating fin all from penetrating, help absorbing heat from CPU core near the outside width of cloth of base plate middle position; Be the width of cloth and penetrate the spaced radiating fin of shape and can form air flow passage around leading to, make the wind of fan can be from inside to outside to around discharge, effectively improve radiating effect.

The utility model has the advantages that good heat dissipation effect, can guarantee effectively that CPU works long hours.

Accompanying drawing is embodiment of the present utility model.

Accompanying drawing 1 is the structural representation after the utility model is installed fan.

Accompanying drawing 2 is the structural representations after the utility model takes off fan.

Accompanying drawing 3 is that the width L of radiating fin 2 overlooks the arrangement architecture schematic diagram when identical.

Accompanying drawing 4 is that the width L of radiating fin 2 overlooks the arrangement architecture schematic diagram when being inequality.

The utility model has radiating fin 2 above conductive sole plate 1, the radiating fin 2 of described conductive sole plate 1 top is a multi-disc, and from inside to outside the width of cloth is penetrated to form and is spaced.

The thickness of described radiating fin 2 is uniform; The middle part of described radiating fin 2 is laid fan 3 to recessed at following recess, and wind is from the downward force feed of interior recess.

The thickness of described radiating fin 2 also can be uneven, adopts the mode that thickness is separated by to arrange, i.e. the mode that is spaced of plate sheet a slice sheet; The middle part of described radiating fin 2 is laid fan 3 to recessed at following recess, and wind is from the downward force feed of interior recess.

Every of the width L of described radiating fin 2 is identical, the structure during arrangement as shown in Figure 3, the middle part of described radiating fin 2 is to recessed, lays fan 3 at recess down.

The width L of described radiating fin 2 is inequality.Structure during arrangement as shown in Figure 4.The middle part of described radiating fin 2 is laid fan 3 to recessed at following recess.

In said structure, be that extending inwardly near base plate is middle position at 2 times recesses of radiating fin.

In the present embodiment, described conductive sole plate 1 is square, also can adopt other shape, as long as can all can with the corresponding shape of the shape of CPU.Radiating fin 2 is arranged for the vertical sheet of penetrating with conductive sole plate 1.Radiating fin 2 can adopt integral body to make with conductive sole plate 1, also can adopt the radiating fin 2 and the mode of conductive sole plate 1 welding to link into an integrated entity.

Radiating fin 2 and conductive sole plate 1 can be made with materials such as aluminium, copper, alloys, and present embodiment is to adopt copper material to make.

It is the structures on plane that another kind of mapped structure of the present utility model can adopt radiating fin 2 upper surfaces, fan 3 is mounted in the upper surface of radiating fin 2, the middle part of just cancelling radiating fin 2 is recessed, the basketball match that makes progress of the middle Zhang, a state in the Zhou Dywnasty of radiating fin 2 stretches that to make its upper surface be the plane, and fan 3 is installed in upper surface.
