Abstract
The utility model relates to a heat dissipation sheet. The heat dissipation sheet comprises a main body and two pins arranged on the main body. The heat dissipation sheet is characterized in that one surface of the main body is provided with a plurality of grooves; groove walls of the groove protrude out from the surface of the main body; and two end portions of the other surface of the main body are respectively provided with two irregular concave clamping positions. According to the heat dissipation sheet of the utility model, one surface of the main body is provided with the plurality of grooves, and the groove walls of the groove protrude out from the surface of the main body, and therefore, the superficial area of the main body can be increased, and the larger the superficial area of the main body is, the better heat dissipation is.
Description
Technical field
The utility model relates to heat abstractor, relates in particular to a kind of 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 surface area of now a lot of CPU radiating fins does not cause radiating effect not good very much.
The utility model content
The utility model has overcome the deficiencies in the prior art, and the 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 fin, it comprises a main body and two PIN pin that are arranged on described main body, it is characterized in that, one surface of described main body is provided with several grooves, the cell wall of described groove protrudes from the table plane of described main body, and the surperficial both ends of another of described main body respectively are provided with two irregular matrix screens.
In preferred embodiment of the utility model, further comprise, the top of described main body is provided with two fixing holes, and described PIN pin is fixed in above described main body by described fixing hole.
In preferred embodiment of the utility model, further comprise, described PIN pin adopts the mode of riveted joint to be fixed on described main body.
In preferred embodiment of the utility model, further comprise, the distance between the groove of described body surfaces is unequal.
In preferred embodiment of the utility model, further comprise, be provided with three convection holes that spacing is equal in the middle of described main body.
In preferred embodiment of the utility model, further comprise, described convection holes is through the thickness face of described main body.
The utility model has solved the defect existed in the background technology, the utlity model has following beneficial effect:
1. employing technique scheme, a surface of main body of the present utility model is provided with several grooves, and the cell wall of groove protrudes from the table plane of described main body, has increased like this surface area of main body, and the larger radiating effect of the surface area of fin is better.
2. the utility model is provided with convection holes in the upper end of main body, strengthens the convection current of fin, strengthens convection current and has accelerated distributing of heat.
3. the utility model arranges the matrix screens at the two ends of main body, conveniently fin is installed on above components and parts.
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 vertical view of the present utility model.
Wherein, 1-main body, 2-convection holes, 3-PIN pin, 4-groove, 5-fixing hole, 6-screens.
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 shown in Figure 1-2, the utility model provides a kind of fin, it comprises a main body 1 and two PIN pin 3 that are arranged on aforementioned body, one surface of aforementioned body is provided with several grooves 4, and the distance of 4 of grooves is unequal, the cell wall of above-mentioned groove 4 protrudes from the table plane of aforementioned body, and the surperficial both ends of another of aforementioned body respectively are provided with two irregular matrix screens 6.Be provided with two fixing holes 5 on the top of main body 1, above-mentioned PIN pin 3 is fixed in above aforementioned body 1 by above-mentioned fixing hole.PIN pin 3 adopts the mode of riveted joint to be fixed on aforementioned body.Be provided with convection holes 2 that three spacings are equal and the convection holes 2 thickness face through aforementioned body 1 in the middle of main body 1.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can, in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on specification, must determine technical scope according to the claim scope.
