Abstract

A radiator comprises a radiating base plate and a plurality of radiating sheets which are integrally formed at the upper end of the radiating base plate and are separated at intervals. All the radiating sheets are divided into two groups and are symmetrically distributed on the two sides of the radiating base plate. The same group radiating sheets are parallel to each other and are outward in an arc shape. Heat is evenly transmitted to the radiating sheets through the radiating base plate. Compared with a traditional radiator, the radiating base plate is large in heat conducting area, the thermal resistance ratio is small, heat transmission speed is quick, all the radiating sheets are outward in an arc shape, accordingly, the contacting area of the whole radiator and air can be enlarged, heat can be radiated into air quickly, in addition, due to the fact that all the radiating sheets are outward in an arc shape, heat radiated by adjacent radiating sheets can form outwards-flowing vortexes in spaces between the adjacent radiating sheets, flowing out of the radiator and radiating of heat are accelerated, therefore, radiating effect is greatly improved, and accordingly the radiator is reasonable in structure and good in radiating effect.

Description

Radiator

Technical field

The utility model relates to a kind of radiator.

Background technology

Present stage, the application of radiator is very extensive, and it is generally by the joint pin of vertically placing, the many fin that radially distribute on 360 degree circumference to be formed by connecting.In use, heater is fixedly mounted on joint pin bottom end face, and the heat that heater produces is like this delivered to top from joint pin bottom, and the heat in joint pin passes on each fin gradually simultaneously, finally by fin by dissipation of heat in air, reach as early as possible the object of heat radiation.Can find out, the heat that heater distributes is to transmit by joint pin, but joint pin exists thermal resistance, and the more difficult bottom from joint pin of heat is delivered to top, is also just difficult to be delivered on fin fast, thereby greatly affects radiating effect.

Summary of the invention

[0003] the purpose of this utility model is to be to overcome the deficiencies in the prior art, and a kind of rational in infrastructure, radiator that radiating effect is good is provided.

In order to solve the technical problem of above-mentioned existence, the utility model is taked following technical proposals:

, it comprises heat-radiating substrate and one-body molded several alternate fin that separate in heat-radiating substrate upper end, all fin are divided into two groups of both sides that are symmetrically distributed in heat-radiating substrate; The fin of same group is parallel to each other and is curved outwardly.

In to the technical scheme of above-mentioned radiator, in these two groups of fin those two of the inside connect back-to-back.

In to the technical scheme of above-mentioned radiator, on the heat-radiating substrate of upper and lower end that is positioned at those two fin that connect back-to-back, be respectively equipped with arc auxiliary heat dissipation sheet, down upward.

Compared with prior art, the beneficial effects of the utility model are: it be by heat-radiating substrate by heat Transmit evenly to each fin, compared with traditional radiator, first by being delivered to after vertical joint pin again by its outer wall, be delivered to this transfer mode on the fin that 360 degree radiation distribute, heat-radiating substrate thermal conductive surface is larger, thermal resistance is smaller, the transmission speed of heat is fast, and all fin are curved outwardly, so just can increase the contact area of whole radiator and air, heat can be dispersed in air more rapidly; In addition, because all fin are arc outwardly, the heat that adjacent like this fin gives out can form outwards mobile whirlpool in the space between adjacent fin, accelerate heat flows, distributes outside radiator, thereby greatly increased radiating effect, therefore of the present utility model rational in infrastructure, radiating effect is good.

Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated:

[accompanying drawing explanation]

Fig. 1 is the schematic perspective view of the utility model embodiment;

Fig. 2 is the top view of the utility model embodiment;

Fig. 3 is that A-A of Fig. 2 is to cutaway view.

[specific embodiment]

, as shown in Figure 1, 2, 3, it comprises heat-radiating substrate 10 and one-body molded several alternate fin that separate 20 in heat-radiating substrate 10 upper ends, all fin 20 are divided into two groups of both sides that are symmetrically distributed in heat-radiating substrate 10; The fin 20 of same group is parallel to each other and is curved outwardly.The utility model in use, heater is arranged on to the bottom of heat-radiating substrate 10, like this, the heat that heater produced in when work just through heat-radiating substrate 10 Transmit evenlies to each fin 20, again by each fin 20 by dissipation of heat in air, reach the object of heat radiation.

As seen from the above, the utility model by heat-radiating substrate 10 by heat Transmit evenly to each fin 20, compared with traditional radiator, first by being delivered to after vertical joint pin again by its outer wall, be delivered to this transfer mode on the fin that 360 degree radiation distribute, heat-radiating substrate 10 thermal conductive surfaces are larger, thermal resistance is smaller, the transmission speed of heat is fast, and all fin 20 are curved outwardly, so just can increase the contact area of whole radiator and air, heat can be dispersed in air more rapidly; In addition, because all fin 20 are arc outwardly, the heat that adjacent like this fin gives out can form outwards mobile whirlpool in the space between adjacent fin, accelerate heat flows, distributes outside radiator, thereby greatly increased radiating effect, therefore of the present utility model rational in infrastructure, radiating effect is good.

In the present embodiment, as shown in Figure 1, 2, 3, in order to make radiator integral more attractive in appearance, those two of the inside of these two groups of fin 20 connect into X-type groups of fins back-to-back; And in order further to improve radiating effect, fully the space utilization of heat-radiating substrate upper end is got up, arc auxiliary

heat dissipation sheet

30,40 under being respectively equipped with upward, entering on the heat-radiating substrate 10 of upper and lower end that is positioned at those two fin that connect back-to-back, between the upper and lower end of they and X-type groups of fins, also formed respectively mobile up and down heat whirlpool, further to accelerate distributing of heat.

In the present embodiment, heat-radiating substrate 10 is circular, and it can be also square, oval etc. certainly.

Although reference above embodiment describes the utility model in detail, but it will be apparent to one skilled in the art that by the disclosure, and in the situation that do not depart from principle of the present utility model and the spiritual scope that described claim limits, can the utility model be made a variety of changes or be revised.Therefore, the detailed description of disclosure embodiment is only used for explaining, rather than is used for limiting the utility model, but is defined by the subject-matter of the claims the scope of protection.
