The heat dissipation fin comprises a main body and a pin arranged on the main body; the vertical surface of the main body is the shape of a rectangle; the height of the rectangle is greater than the length of the rectangle; and the pin is arranged at the bottom end of the vertical surface of the main body, namely, on a length edge of the rectangle. The main body of the heat dissipation fin of the utility model is a vertical cuboid, and the height of the cuboid is greater than the length of the cuboid, and the pin is arranged at the bottom end of the vertical surface of the main body, namely, on the length edge of the rectangle, and therefore, all area of the main body is a heat dissipation area. Thus, the heat dissipation fin is advantageous in large surface area and excellent heat dissipation effect.

Description

A kind of radiating fin
Technical field
The utility model relates to fin, relates in particular to a kind of radiating fin.
Background technology
Fin is a kind of device to the easy heat-generating electronic elements heat radiation in electrical equipment, how by aluminium alloy, brass or bronze are made tabular, sheet, splintery etc., as the cpu central processing unit in computer will be used sizable fin, the power tube in television set in power supply pipe, line pipe, amplifirer all will be used fin.General fin in use will be coated with the last layer heat-conducting silicone grease at electronic component and radiating rib contact surface, and the heat that components and parts are sent is more effective to be transmitted on fin, then is dispersed in surrounding air through fin.
Fin on market is different because of purposes now, so the shape of fin and heat sinking function are different.For example, the CPU heat disperse be mainly by the conduction mode realize, its medium directly contacted with processor is fin, fin has absorbed heat and by the form of convection current, heat has been dissipated, in the process of heat loss through convection, radiating effect is mainly determined by the surface area of radiating fin size.The radiating effect of the radiating fin of now a lot of CPU radiating fins is not good.
The utility model content
The utility model has overcome the deficiencies in the prior art, and the radiating fin of the large good heat dissipation effect of a kind of surface area is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of radiating fin, it comprises main body and is arranged on the PIN pin on described main body, the vertical surface of described main body is rectangle, described rectangular height is greater than its length, and the bottom that described PIN pin is arranged on the vertical surface of described main body is on described rectangular length sides.
In preferred embodiment of the utility model, further comprise, described main body is three-dimensional cuboid, and the height of described main body is 23mm, and the thickness of described main body is 1.5mm, and the ratio of the thickness of described main body and height is less than 0.1.
In preferred embodiment of the utility model, further comprise, described PIN pin is convex shape, and the part of described PIN pin projection is described main body and miscellaneous part connecting portion, and described PIN pin bossing protrudes from the length sides of described main body.
In preferred embodiment of the utility model, further comprise, described main body is provided with convection holes, and described convection holes is located at another length sides one side relative with described PIN pin, and described convection holes is through the thickness of described main body.
In preferred embodiment of the utility model, further comprise, described convection holes is octagon.
In preferred embodiment of the utility model, further comprise, described PIN pin is fixed on described main body by the mode of riveted joint.
In preferred embodiment of the utility model, further comprise, described PIN pin and described main body riveting place are three-back-shaped.
In preferred embodiment of the utility model, further comprise, several dismountable pallets are set on described moving belt.
The utility model has solved the defect existed in the background technology, the utlity model has following beneficial effect:
1. employing technique scheme, fin of the present utility model is vertical cuboid, it highly is greater than length, and the bottom that the PIN pin is arranged on the vertical surface of main body is on described rectangular length sides, the entire area of main body is all area of dissipation like this, and surface area is large, good heat dissipation effect.
2. the height of main body of the present utility model is 23mm, the thickness of main body is 1.5mm, the ratio of the thickness of described main body and height is about 0.065, be far smaller than 0.1, the size of the utility model main body effectively reduces thickness high ratio, because the ratio of thickness and height is less, just mean that the radiating fin of unit volume just can be done more intensive, quantity is more, and the surface area of efficiently radiates heat is just larger, and thermal diffusivity is just better.
3. the utility model is provided with convection holes in the upper end of main body, strengthens the convection current of radiating fin, strengthens convection current and has accelerated distributing of heat.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front view of the present utility model.
Fig. 2 is end view of the present utility model.
Fig. 3 is vertical view of the present utility model.
Wherein, 1-main body, 2-PIN pin, 3-convection holes.
Embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Figure 1-3, the utility model provides a kind of radiating fin, it comprises main body 1 and is arranged on the PIN pin 2 on aforementioned body, the vertical surface of aforementioned body 1 is rectangle, above-mentioned rectangular height is greater than its length, and the bottom that above-mentioned PIN pin 2 is arranged on the vertical surface of aforementioned body is on above-mentioned rectangular length sides.The entire area of main body 1 is all area of dissipation like this, and surface area is large, good heat dissipation effect.
Concrete in the utility model embodiment, main body 1 is three-dimensional cuboid, and the height of aforementioned body is 23mm, and the thickness of aforementioned body is 1.5mm, and the ratio of the thickness of aforementioned body and height is about 1.06, is far smaller than 0.1.This size effectively reduces thickness high ratio, because the ratio of thickness and height is less, just means that the radiating fin of unit volume just can be done more intensive, and quantity is more, and the surface area of efficiently radiates heat is just larger, and thermal diffusivity is just better.
Be provided with convection holes 3 on main body, and convection holes 3 is octagon, above-mentioned convection holes 3 is located at another length sides one side relative with above-mentioned PIN pin 2, and above-mentioned convection holes 3 is through the thickness of aforementioned body 1.The existence of convection holes 3 can be strengthened the convection current of radiating fin, strengthens convection current and has accelerated distributing of heat.
