Abstract
The utility model discloses an aluminum alloy radiating fin comprising a bottom plate and fins, wherein the fins are fixed on the bottom plate, and two lateral surfaces of each fin are provided with crinkles. A plurality of raised lines are also arranged on two surfaces of each fin. The raised lines are parallel to the length direction of the fins. A plurality of grooves are also arranged on two surfaces of each fin and are parallel to the length direction of the fins. By adopting the aluminum alloy radiating fin, as two lateral surfaces of the fin are provided with the crinkles, the fin of the same height has more radiating areas than a fin provided with smooth and straight lateral surfaces, thereby leading the radiating effect to be better. A plurality of raised lines or grooves can also be arranged on two surfaces of each fin, thus further enlarging the radiating areas of the fin, and further enhancing the radiating effect.
Description
Technical field
The utility model relates to a kind of fin of aluminium alloy, particularly relates to a kind of aluminum alloy heat sink of strengthening radiating effect.
Background technology
In existing mechanical, chemical industry or the instrument and meter industry, need dispel the heat to some heating working position, common way is to use some aluminum alloy heat sinks, aluminum alloy heat sink generally comprises base plate and fin, in use, base plate is close to the heating working position, because the thermal conductivity coefficient of aluminium alloy is higher, the heat of heating working position is transmitted on the aluminum alloy heat sink, utilizes fin that heat is dispersed in the air again.Existing this aluminum alloy heat sink produces under the bigger occasion of heat in some heating working position, and radiating effect is not very desirable just.
Summary of the invention
For overcoming above-mentioned defective, the utility model aims to provide a kind of aluminum alloy heat sink of further enhance heat effect.
The technical scheme that adopts is: a kind of aluminum alloy heat sink, comprise base plate and fin, and described fin is fixed on the base plate, and two sides of described fin have ripple.Also be provided with several raised lines on two surfaces of described fin.Described raised line is parallel with the length direction of fin.Also be provided with several grooves on two surfaces of described fin.Described groove is parallel with the length direction of fin.
Adopted aluminum alloy heat sink of the present utility model, because two sides of its fin have ripple, make the fin of same height have than the more area of dissipation of flat sides set, radiating effect is also just better, the utility model can also also be provided with several raised lines or groove on two surfaces of fin, further increased the area of dissipation of fin, also just further enhance heat effect.
Description of drawings
Fig. 1 is a sectional structure chart of the present utility model;
Fig. 2 is the fin section partial enlarged drawing with raised line of the present utility model;
Fig. 3 is the fin section partial enlarged drawing with groove of the present utility model.
Among the figure: 1-base plate, 2-fin, 3-raised line, 4-groove.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of aluminum alloy heat sink, comprise base plate 1 and fin 2, described fin 2 is fixed on the base plate 1, and two sides of described fin 2 have ripple.Aluminum alloy heat sink of the present utility model can adopt the aluminum alloy heat extrusion forming process to make.
As shown in Figure 2, also be provided with several raised lines 3 on two of described fin 2 surfaces.In order to reach machinability, described raised line 3 is parallel with the length direction of fin 2.
As shown in Figure 3, also be provided with several grooves 4 on two of described fin 2 surfaces.In order to reach machinability, described groove 4 is parallel with the length direction of fin 2.
Bellows-shaped on two sides of described fin 2 can be the bellows-shaped of sine curve or other form, and the shape of described raised line 3 and groove 4 can be semicircle or triangle or other shape.
Adopted aluminum alloy heat sink of the present utility model, because two sides of its fin 2 have ripple, make the fin 2 of same height have than the more area of dissipation of flat sides set, radiating effect is also just better, the utility model can also also be provided with several raised lines 3 or groove 4 on two surfaces of fin 2, further increased the area of dissipation of fin, also just further enhance heat effect.
