The utility model discloses a multi-row core step type cooling fin. The utility model is characterized in that the multi-core step type cooling fin consists of a fixed face, an extension face and a connecting face, wherein the fixed face and the extension face are connected through the connecting face to form a stepped shape, and two rows or a plurality of rows of screw holes are formed on the fixed face and are used for fixing electronic components. The multi-row core step type cooling fin is mainly used for auxiliary heat dissipation of a circuit board; based on the characteristic of the stepped shape of the cooling fin, surrounding electronic components on the circuit board are avoided; meanwhile, the heat dissipation area is expanded, and the heat dissipation effect is improved; moreover, the plurality of rows of screw holes are formed on the fixed face and are used for fixing the electronic components, and therefore, the assembly requirements of different specifications of electronic components can be simultaneously met. The multi-row core step type cooling fin is simple in structure and high in adaptability, and has good heat dissipation effect.
Description
Technical field
The utility model belongs to circuit board heat radiation field, particularly a kind of many rounds staged 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 with circuit board, and through its radiating surface heat transferred is gone out; Thereby reach cooling-down effect, but traditional fin shape is merely the plane of a full wafer, the area of its radiating effect and radiating surface is directly proportional; Strengthen radiating effect if desired; Then radiating surface need be to expansion all around, and the 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; Usually only be provided with the screw that a row is used to install electronic component on traditional in addition fin; And the electronic component specification on the same single row of holes fin possibly have difference, and the pin length of its electronic component is also inconsistent, and therefore traditional single row of holes fin is not suitable for this type of situation.
Summary of the invention
The utility model technical problem to be solved is to overcome the deficiency that exists in the prior art, provides a kind of simple in structure, and adaptability is strong, many rounds staged fin of good heat dissipation effect.
For solving the problems of the technologies described above; The utility model provides a kind of many rounds staged fin; It is characterized in that: said many rounds staged 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 two rows or the screw that is used for fixing electronic component of arranging more.Two rows or many rows' screw goes for the installation requirements of the electronic component of different specification size, strengthening its adaptability, and through screw electronic component, stationary plane and circuit board is connected to a fixed; Simple in structure; Easy for installation, stepped structure make extended surface can the breaking circuit plate surface, built on stilts electronic component around top; Electronic component strengthens radiating effect to the restricted problem of heat sink sizes on the circuit board to solve.
Aforesaid many rounds staged fin is characterized in that: said stationary plane is provided with the screw that two rows are used for fixing electronic component.
Aforesaid many rounds staged fin, it is characterized in that: said extended surface is provided with screw.The screw that extended surface is provided with can be connected with other fixing point positions through screw under the situation of conditions permit, with further fixing many rounds staged fin, improves stability.
The beneficial effect that the utility model reached:
Utilize the stairstepping characteristics of fin, avoid the peripheral electronic component on the circuit board.Enlarge area of dissipation simultaneously, strengthen radiating effect, stationary plane is provided with the screw that many rows are used for fixing electronic component simultaneously, can satisfy the assembling demand of the electronic component of different specification size simultaneously, and simple in structure, adaptability is strong, good heat dissipation effect.

Embodiment
Below in conjunction with accompanying drawing the utility model 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; Stationary plane 1 links to each other through joint face 2 with extended surface 3 and forms stairstepping; Stationary plane 1 is provided with the screw 4 that two rows are used for fixing electronic component, has the electronic component of two different sizes to be installed on the stationary plane 1 respectively, also is provided with the fixedly screw 5 of usefulness 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 stationary plane 1, electronic component 9 and circuit board 6 are connected to a fixed; The screw 4 of the electronic component 9 corresponding diverse locations of different specification size, 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; 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 board edge, 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 stationary plane 1, electronic component 9 and circuit board 6 are connected to a fixed, the screw 4 of the electronic component 9 corresponding diverse locations of different specification size, and with the outside of extended surface 3 towards circuit board 6; Away from circuit board 6; Be provided with screw 5 through extended surface 3, can it be connected with peripheral other fixing point positions with screw, to improve stability.
The utility model 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; Enlarge area of dissipation simultaneously, strengthen radiating effect, stationary plane is provided with the screw that many rows are used for fixing electronic component simultaneously; Can satisfy the assembling demand of the electronic component of different specification size simultaneously; Simple in structure, adaptability is strong, good heat dissipation effect.
Above embodiment limits the utility model never in any form, every above embodiment is made with the equivalent transformation mode other improve and use, all belong to the protection range of the utility model.
