The heat radiation fin with the auxiliary fixed parts is mainly used for assisting the heat radiation of a circuit board. By adopting a vertical-type structure, the installation space is saved, the structure is simple, and convenience in assembling can be realized; and the auxiliary fixed parts are matched with each other to fix the heat radiation fin main body, so the stability is good, the heat radiation can be realized for the electronic element, and the heat radiation effect is good.
Description
Technical field
The utility model belongs to circuit board heat radiation field, particularly a kind of fin that is provided with auxiliary fixing member.
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 reaches cooling-down effect; Traditional fin shape is the plane of a full wafer, directly is fixed on the circuit board through screw, can on fin, add electronic components simultaneously; Electronic component is dispelled the heat, but traditional heat radiating fin structure is too simple, it is too big on electric hot plate, to take up space; It is bigger that limitation is installed, and its stable installation property is also relatively poor, especially when fin is installed in board edge; Limited because of installing space on the circuit board, usually the part fin is stretched out circuit board, fin has only part to link to each other with circuit board; Gravity distributes uneven, be easy to generate loosening, poor stability.
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, is convenient to assembling, good stability, the fin that is provided with auxiliary fixing member of good heat dissipation effect.
For solving the problems of the technologies described above; The utility model provides a kind of fin that is provided with auxiliary fixing member, comprises heat sink body, it is characterized in that: said heat sink body is made up of stationary plane and radiating surface; Said stationary plane vertically links to each other with radiating surface; Said stationary plane is provided with fixing threaded hole, and said radiating surface is provided with the screw that is used for fixing electronic component, and the horizontal two ends of said radiating surface are respectively equipped with an auxiliary fixing member.Heat sink body is a vertical structure, and stationary plane is provided with fixing threaded hole, through the screw fixation that linked to each other with circuit board; Radiating surface is provided with the screw that is used for fixing electronic component, plays thermolysis perpendicular to circuit board, therefore on circuit board, takes up room very little in heat sink body; And be convenient to the assembling, in the time need dispelling the heat to the edge of circuit board, with radiating surface near board edge; Stationary plane is fixed on the outside fixing point position of circuit board, and the auxiliary fixing member with the radiating surface two ends links to each other with circuit board simultaneously, can make between heat sink body and the circuit board be connected more stable; Electronic component is vertically mounted on the radiating surface; Saved the installing space on the circuit board more, can obtain the electronic component better heat radiating effect simultaneously, assembling is also convenient.
The aforesaid fin that is provided with auxiliary fixing member is characterized in that: said auxiliary fixing member is made up of supporting surface and platform, and said supporting surface links to each other with radiating surface, and said supporting surface and platform are connected to form L type structure, and said platform is provided with screw.The auxiliary fixing member of L type structure is simple in structure, and platform is provided with screw, links to each other stable installation with circuit board through screw.
The aforesaid fin that is provided with auxiliary fixing member is characterized in that: said radiating surface, stationary plane and auxiliary fixing member are formed in one.Heat sink body and auxiliary fixing member are one-body molded, and structural stability is good.
The beneficial effect that the utility model reached:
Vertical structure is saved installing space, and is simple in structure, is convenient to assembling, auxiliary fixing member matching and fixing heat sink body, and good stability can dispel the heat good heat dissipation effect to electronic component.
Description of drawings
Fig. 1 is the perspective view of the utility model;
Fig. 2 is the side structure sketch map of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Like Fig. 1, shown in Figure 2, heat sink body is made up of stationary plane 1 and radiating surface 2, and stationary plane 1 is provided with fixing threaded hole 3; Can on circuit board or with other fixing point positions, link to each other through screw, radiating surface 2 is provided with the screw 4 that is used for fixing electronic component, is connected with electronic component through screw; Can dispel the heat to electronic component, radiating surface 2 two ends are provided with auxiliary fixing member, and auxiliary fixing member is on supporting surface 5 and the platform 6 L type structure that is formed by connecting; Supporting surface 5 links to each other with radiating surface 2, and platform 6 is protruding, and platform 6 is provided with screw; Can link to each other with circuit board through screw, strengthen the stable installation property of heat sink body, electronic component is fixed on the radiating surface 2; Perpendicular with circuit board, so only on circuit board, take the pin space, saved the limited plane space of circuit board.
Heat sink body and auxiliary fixing member are formed in one; Guaranteed structural stability; Because electronic component is perpendicular to the circuit board installation, can carry out clubfoot during practical operation to the pin of electronic component and handle, reduce the influence of stress to electronic component; Make the assembling of electronic component and circuit board more stable, longer service life.
The utility model is mainly used in circuit board is carried out auxiliary heat dissipation, and vertical structure is saved installing space, and is simple in structure, is convenient to assembling, auxiliary fixing member matching and fixing heat sink body, and good stability can dispel the heat good heat dissipation effect to electronic component.
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.
