Abstract
The invention discloses a stepped radiating fin. The stepped radiating fin is characterized in that: the stepped radiating fin is formed by a fixed plane, an extension surface and a connection surface; the fixed plane is connected with the extension surface through the connection surface so as to form a stepped shape; the fixed plane is provided with a screw hole which is used to fix an electronic component. The stepped radiating fin is mainly used to carry out auxiliary cooling to a circuit board. Using a stepped-shaped characteristic of the radiating fin, the surrounding electronic component on the circuit board can be avoided. A heat dissipation area can be enlarged and simultaneously a heat dissipation effect can be enhanced. A structure is simple and adaptability is strong. The heat dissipation effect is good.
Description
Technical field
The invention belongs to circuit board heat radiation field, particularly a kind of stairstepping fin.
Background technology
On the circuit board owing to integrated a large amount of electronic components; Can discharge a large amount of heats during work, cause the circuit board temperature to raise, the too high job stability that can influence electronic component of temperatures at localized regions; Therefore need to improve the radiating effect of circuit board; Reduce working temperature, guarantee its stability, increase the service life.
Common radiating mode is a finned on circuit board; Through the heat fast Absorption of fin, and heat transferred is gone out, thereby reach cooling-down effect through its radiating surface with circuit board; But traditional fin shape is merely the plane of a full wafer; The area of its radiating effect and radiating surface is directly proportional, and strengthens radiating effect if desired, and then radiating surface need be to expansion all around; Electronic component to the circuit board upper periphery has interference easily, and it is installed and also receives the restriction that electronic component is arranged on the circuit board.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency that exists in the prior art, provides a kind of simple in structure, and adaptability is strong, the stairstepping fin of good heat dissipation effect.
For solving the problems of the technologies described above; The present invention provides a kind of stairstepping fin; It is characterized in that: said stairstepping fin is made up of stationary plane, extended surface and joint face; Said stationary plane links to each other through joint face with extended surface and forms stairstepping, and said stationary plane is provided with the screw that is used for fixing electronic component.During assembling, stationary plane and circuit board fit, and through screw electronic component, stationary plane and circuit board three are fixed, and joint face is high with the extended surface holder; Form stairstepping,, avoided interference electronic component on the circuit board so that extended surface can be maked somebody a mere figurehead above the electronic component on the circuit board; Also overcome the limited space property on the circuit board, taken less circuit board surface area, but enlarged area of dissipation through built on stilts extended surface; To improve radiating effect, simple in structure, easy for installation.
Aforesaid stairstepping fin is characterized in that: said extended surface is provided with screw.When stationary plane is installed in board edge, can extended surface be arranged in the circuit board outside, can use the fixing point position beyond screw and the circuit board to fix through the screw on the extended surface, to improve stable installation property, littler to the interference of circuit board.
The beneficial effect that the present invention reached:
Utilize the stairstepping characteristics of fin, avoid the peripheral electronic component on the circuit board, enlarge area of dissipation simultaneously, strengthen radiating effect, simple in structure, adaptability is strong, good heat dissipation effect.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is a kind of fit of the present invention on circuit board;
Fig. 3 is the another kind of fit of the present invention on circuit board.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in Figure 1, the stairstepping fin is made up of stationary plane 1, joint face 2 and extended surface 3, and stationary plane 1 links to each other through joint face 2 with extended surface 3 and forms stairstepping, is useful on the screw 4 of fixed electronic element on the stationary plane 1, also is provided with screw 5 on the extended surface 3.
As shown in Figure 2; When the stairstepping fin is assemblied in circuit board 6 middle parts, to be close to mutually with circuit board 6 by stationary plane 1, the screw of reserving on the screw 4 on the stationary plane 1 and the circuit board 67 is corresponding; Through screw 8 that stationary plane 1 is fixing with circuit board 6; Also can electronic component 9 be fixed on the stationary plane 1 simultaneously, the height of joint face 2 depends on the electronic component height of circuit board 6 surroundings, so that extended surface 3 can be maked somebody a mere figurehead above peripheral electronic component by joint face 2; To avoid, improve radiating effect to the interference of electronic component on every side.
As shown in Figure 3, when the stairstepping fin is assemblied in circuit board 6 edges, be close to mutually with circuit board 6 by stationary plane 1; The screw of reserving on screw 4 on the stationary plane 1 and the circuit board 67 is corresponding; Through screw 8 that stationary plane 1 is fixing with circuit board 6, also can electronic component 9 be fixed on the stationary plane 1 simultaneously, and with the outside of extended surface 3 towards circuit board 6; Away from circuit board 6; Screw 5 through extended surface 3 is provided with can be connected it with screw, to improve stability with peripheral other fixing point positions.
The present invention is mainly used in circuit board is carried out auxiliary heat dissipation, utilizes the stairstepping characteristics of fin, avoids the peripheral electronic component on the circuit board, enlarges area of dissipation simultaneously, strengthens radiating effect, and simple in structure, adaptability is strong, good heat dissipation effect.
Above embodiment limits the present invention never in any form, and every other improvement and application that above embodiment is made with the equivalent transformation mode all belongs to protection scope of the present invention.
