Abstract

Provided is a coating type heat radiating components which can greatly improve heat radiating effect, characterized in that a fan is arranged in a hollow heat radiating body which is manufactured by foamed metal materials. Due to the mass micro pores arranged in the foamed metal, the heat radiating area of the radiating body can be increased greatly, thus heat radiating can be performed more easily.

Description

The clad type radiating component

The utility model relates to a kind of clad type radiating component, particularly relates to the radiating component that a kind of radiating effect increases substantially.

For making machine or device under long-time, the state that runs up, still can keep normal operational function, generally the suitable position at this machine or device is provided with a radiating component, so that this machine or device can be distributed as early as possible because of the heat that perseveration was produced, avoid machine or device influences normal operation because of overheated, described machine or the relevant device that installs especially with computer are best representative instance.

Known a kind of radiating component, as shown in Figure 1, it is provided with a fan 10 and a fins group 11, this fins group 11 also is equipped with a plurality of continuous fins 110 so that conduct heat, when fan 10 rotations and drive air-flow, flow path channel by 110 of the heat radiation of each fin 110 and each fins is discharged hot-air with the A-A direction, because the configuration of each fin 110 can be quickened heat radiation, but because fin 11 is arranged on the bottom of fan 10, but the area and the direction of the wandering heat of air feed are less, and air-flow must flow out from the passage of 110 of each fins, and flow resistance is bigger, so the radiating effect that can bring into play is comparatively limited.

Known another kind of radiating component, as shown in Figure 2, it is provided with a fan 12 and a pair of first fin 13 and a pair of second fin 14, rotate the air-flow that is driven by fan 12, hot-air is flowed out with B-B and C-C direction from the gas channel that two first fins 13 and two second fins 14 are constituted, because this heat abstractor is to cause two heat exchange directions with first fin 13 with good heat transfer and the configuration of second fin 14, the more above-mentioned known radiating component of its radiating effect is good, yet, since each first fin 13 and second fin 14 around be arranged on fan 12 around, but the area of the wandering heat of air feed and direction only limit to the position at the fin place around the fan, and the shape of two first fin 13 and two second fins 14 makes current path narrow, thereby cause bigger gas-flow resistance, so on radiating effect, still have the space of improving.

Limited for the direction and the area that effectively overcome fins group heat supply exchange in the known radiating component, the configuration mode of each fin causes the bigger shortcoming of gas-flow resistance, has proposed the utility model " clad type radiating component ".

Main purpose of the present utility model provides a kind of clad type radiating component, makes the area of dissipation multiplication, and gas-flow resistance is less, reaches the effect that radiating effect increases substantially.

Principal character of the present utility model is to be in the heat radiator body of hollow shape one a fan is set, this heat radiator body adopts the foaming metal made, the foaming metal material is preferable selection with aluminum metal, because the large quantity micropore crack that the foaming metal material is had and the hollow structure of heat radiator body, the thermal current of fan driven rotary can be discharged from heat radiator body rapidly, thereby reach the effect of quick heat radiating.

For achieving the above object, the utility model is to be in the heat radiator body of hollow shape one a fan is set, and this heat radiator body adopts foaming metal made.

Be the technological means and the effect thereof that achieve the above object, feature adopted, now exemplify preferred embodiment and accompanying drawings is as follows:

Fig. 1 is the stereogram of known a kind of radiating component;

Fig. 2 is the stereogram of known another kind of radiating component;

Fig. 3 is the three-dimensional exploded view of the utility model preferred embodiment;

Fig. 4 is the part bottom view among Fig. 3;

Fig. 5 is the end view of Fig. 3.

As shown in Figure 3, clad type radiating component 2 of the present utility model comprises that one is the heat radiator body 3 and a fan 4 of hollow shape, and wherein this heat radiator body 3 adopts the foaming metal made, and this foaming metal material is preferable selection with aluminum metal.

With reference to Fig. 4 and Fig. 5, when fan 4 starting rotations, the air of heat radiator body 3 inside promptly begins to flow thereupon, because of heat radiator body 3 is to be shaped to hollow member also to form with the foaming metal made, so the inside of heat radiator body 3 will constitute a hot gas cycle path that gas-flow resistance is minimum, but be distributed with a large amount of exchange of micro-pore supplied gas and heat radiation on the heat radiator body 3, that is to say, these micro-pores have extremely a large amount of area of dissipations, so can increase radiating effect significantly; Secondly, because of the foaming metal material is preferable selection (being so-called foaming aluminium) with the extremely excellent aluminum metal of thermal diffusivity again, thermal current when heat radiator body 3 inside begins circulation time, because a large amount of micro-pores and the good thermal diffusivity of itself material can make the hot-air of heat radiator body 3 inside flow to the external world rapidly and carry out heat exchange reaction.

Have again, because heat radiator body 3 is to use the foaming metal made fully, its area of dissipation will increase considerably, so when fan 4 drives the air flows of heat radiator body 3 inside, hot-air can flow to the external world by the micro-pore that each surface spread all on the heat radiator body 3, in other words, when heat radiator body 3 is a rectangular hexahedron, air is flowed on six planes and flow out, when heat radiator body 3 is shaped to a cylinder, then can make inner air produce the purpose that convection action reaches heat radiation by end face, bottom surface and periphery and outside air.

In sum, its structure of the utility model " clad type radiating component " is to be in the heat radiator body of hollow shape one a fan is set, and this heat radiator body adopts the foaming metal made to form, this foaming metal material is preferable selection with aluminum metal again, because heat radiator body is the hollow shape member, the large quantity micropore crack that foaming metal had, and the excellent heat radiation of aluminum metal itself, the current path that heat radiator body was provided and the area of dissipation that form with the manufacturing of foaming aluminum fully will be increased considerably, so when making air in the heat radiator body form air-flow in the fan entry into service, each surface of heat radiator body can be carried out a large amount of heat exchanges and be reached the effect of rapid heat radiation, therefore, radiating component in the known technology can obtain significantly to improve in " clad type radiating component " of the present utility model because of the direction that is subjected to each fin and the limited problem of restriction radiating effect of spatial configuration.

" clad type radiating component " of the present utility model can reach above-mentioned purpose that discloses and effect really, possesses practicality and progressive really.

Above-mentioned accompanying drawing that discloses and explanation only are for explanation the utility model embodiment, are not for limiting enforcement of the present utility model; Other equivalences that those of ordinary skill in the art makes according to feature category of the present utility model change or modify, and all should be included in following the application's case claims scope.
