Abstract

Disclosed is a radiating element including a radiating element body and a plurality of radiating fins peripherad and radially extended from the center of the radiating element body. The radiating fin is provided with a bended part which is circled around the radiating element body to be a circular bended part. The radiating element of the utility model can produce convection cyclone and can improve radiating efficiency.

Description

Radiating piece

[technical field]

The utility model relates to a kind of radiating piece.

[background technology]

Along with electronic component, especially the continuous lifting of the travelling speed of the CPU (central processing unit) of computer, also more and more high to the requirement of its radiating efficiency, on electronic component, add the radiating mode of heat radiator and radiator fan, because effect is direct, cost is low, therefore widely utilized.

But because this electronic component is positioned at the penetralia or the bottom of body mostly, if the structure of heat radiator is not good, can hinder the heat dispatch because of the covering of heat radiator and fan on the contrary, as Fig. 6 and known heat radiator A shown in Figure 7, the combination of the heat abstractor of radiator fan B and electronic component C, this heat radiator A is arranged on the electronic component C, radiator fan B is arranged on the heat radiator A, the heat of electronic component C conducts to heat radiator A, produce cooling air with heat radiator A by radiator fan B again, the heat of electronic component C disperses, because the fin A1 of this heat radiator A becomes vertical, cause heat to stagnate and between fin A1, can't discharge smoothly, hinder heat radiation.

For another another kind of known heat radiator D shown in Figure 8, the top of this kind heat radiator D has a recess D2 for inserting radiator fan E, has most groove D1 around it, and this groove D1 must mill out one by one with milling cutter, not only manufacturing process is very loaded down with trivial details, time-consuming, take a lot of work, the first finished product burr that mill out are big, must processing finishing, moreover, its groove D1 system is level and smooth straight-through ditch shape, so heat easily stagnates and can't discharge smoothly between groove D1, hinders heat radiation.

[utility model content]

The purpose of this utility model is to provide a kind of radiating piece, can produce the convection current cyclone, can improve radiating efficiency.

The utility model provides a kind of radiating piece, comprises that radiating piece body and majority extend radial radiating fin by this radiating piece body center towards on every side, and it is characterized in that: this radiating fin is provided with the kink of bending.

Described radiating piece is characterized in that: the kink of this radiating fin is around being provided with around this radiating piece body, forming a ring-type kink.

Described radiating piece is characterized in that: the center of top of this radiating piece body is provided with a recess.

Described radiating piece is characterized in that: the center of this radiating piece body is provided with a copper material, and the bottom surface of the bottom surface of this copper material and this radiating piece body is positioned at same plane.

Described radiating piece is characterized in that: the center of top of this radiating piece body comprises the end face of this copper material, is provided with a recess.

Radiating piece of the present utility model, the suitable position of its radiating fin is provided with kink, can produce the convection current cyclone, improve radiating efficiency, has industrial utilization.

[description of drawings]

Detailed construction of the present utility model, will be more clear and definite by following detailed description, certainly, the utility model is at some in addition on part, or allow in the arrangement of part in addition different, but selected embodiment, then in this instructions, described in detail, and in accompanying drawing, showed its structure, so that technology contents of the present utility model further discloses is clear.

[embodiment]

Referring to figs. 1 through Fig. 3, radiating piece of the present utility model, what comprise radiating piece body 10 and majority extends radial fin 11 by these radiating piece body 10 centers towards on every side, the center of this radiating piece body 10 has a center pit 14, in this center pit 14, be provided with a copper material 20, the bottom surface 21 of this copper material 20 constitutes a smooth bottom 15 with the bottom surface of this radiating piece body 10 12, the center of top of this radiating piece body 10 comprises the end face of this copper material 20, has a recess 13, suitable position in this fin 11 is provided with kink 111, as shown in Figure 4, originally be the fin 11 of smooth-going arcuation through this kink 111 of machine-shaping, this kink 111 is around being provided with around this radiating piece body 10, forming a ring-type kink.

See also Fig. 5 again, the utility model and radiator fan 70, electronic component 80 combinations, the central shaft 71 of such radiator fan 70 just is arranged at the recess 13 of this radiating piece body 10, the bottom surface 21 of this copper material 20 is smooth on this electronic component 80 with the smooth bottom 15 that the bottom surface of this radiating piece body 10 12 constitutes, the heat of electronic component 80 conducts to radiating piece body 10 and copper material 20 simultaneously, therefore the thermal conductivity of more traditional aluminium extruded type heat radiator is good, moreover, as radiator fan 70 running Hous, the cooling air of its generation not only can directly blow to radiating piece body 10, copper material 20, electronic component 80, simultaneously, because of the utlity model has the fin 11 of band kink 111, when cooling air blows to this kink 111, can produce the convection current cyclone, therefore but accelerated heat distributes and dispatch unlikely stagnating between fin 11.

Above explanation and diagram only be the structure of the selected embodiment of the utility model, in this usefulness of confession explanation only, when can not be in order to limit protection domain of the present utility model.
