The radiating fin is characterized in that: the radiating fin body is composed of a fixed plane and a heat radiation plane. The fixed plane and the heat radiation plane are vertically connected. The fixed plane is provided with a fixing screw. The heat radiation plane is provided with a screw used for fixing an electronic component. Two lateral ends of the heat radiation plane are provided with an auxiliary fixed part respectively. The radiating fin is used for carrying out auxiliary heat radiation on a circuit board, vertical type structure of the radiating fin saves installation space, structure is simple and assembling is convenient. The auxiliary fixed parts cooperate to fix the radiating fin body, stability is good, the electronic component is subjected to heat radiation, and a heat radiation effect is good.
Description
Technical field
The invention belongs to the heat dissipation for circuit board 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 amount of heat during work, cause the circuit board temperature to raise, the too high job stability that can affect 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 finned on circuit board, absorb fast by the heat of fin with circuit board, and by its radiating surface heat is passed, thereby reach cooling-down effect, traditional fin shape is the plane of a full wafer, directly be fixed on the circuit board by screw, simultaneously can add electronic components at fin, electronic component is dispelled the heat, but traditional heat radiating fin structure is too simple, it is too large to take up space on electric hot plate, it is larger that limitation is installed, and it is also relatively poor that it installs stability, especially when fin is installed in board edge, because of installing space on the circuit board limited, usually the part fin is stretched out circuit board, fin only has part to link to each other with circuit board, and gravity distributes uneven, produce easily and become flexible poor stability.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies 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 invention provides a kind of fin that is provided with auxiliary fixing member, comprise heat sink body, it is characterized in that: described heat sink body is comprised of stationary plane and radiating surface, described stationary plane vertically links to each other with radiating surface, described stationary plane is provided with fixing threaded hole, and described radiating surface is provided with the screw for fixed electronic element, and the horizontal two ends of described radiating surface are respectively equipped with an auxiliary fixing member.Heat sink body is vertical structure, stationary plane is provided with fixing threaded hole, by the screw fixation that linked to each other with circuit board, radiating surface is provided with the screw for fixed electronic element, play thermolysis perpendicular to circuit board, therefore take up room very little in heat sink body at circuit board, and be convenient to assembling, in the time need to dispelling the heat to the edge of circuit board, with radiating surface near board edge, stationary plane is fixed on the fixing point position of circuit board outside, 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, more saved the installing space on the circuit board, can obtain the radiating effect good to electronic component simultaneously, assembling is also convenient.
The aforesaid fin that is provided with auxiliary fixing member is characterized in that: described auxiliary fixing member is comprised of supporting surface and platform, and described supporting surface links to each other with radiating surface, and described supporting surface and platform are connected to form the L-type structure, and described 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 with circuit board by screw, installs stable.
The aforesaid fin that is provided with auxiliary fixing member is characterized in that: described 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 present invention reaches:
Vertical structure is saved installing space, and is simple in structure, is convenient to assembling, and auxiliary fixing member is fixed heat sink body, and good stability can dispel the heat to electronic component good heat dissipation effect.
Description of drawings
Fig. 1 is perspective view of the present invention;
Fig. 2 is side structure schematic diagram of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Such as Fig. 1, shown in Figure 2, heat sink body is comprised of stationary plane 1 and radiating surface 2, stationary plane 1 is provided with fixing threaded hole 3, can be fixed by screws on the circuit board or with other fixing point positions and link to each other, radiating surface 2 is provided with the screw 4 for fixed electronic element, be connected with electronic component by screw, can dispel the heat to electronic component, radiating surface 2 two ends are provided with auxiliary fixing member, and auxiliary fixing member is by supporting surface 5 and the platform 6 L-type structure that is formed by connecting, and supporting surface 5 links to each other with radiating surface 2, platform 6 is protruding, platform 6 is provided with screw, can link to each other with circuit board by screw, strengthens the installation stability of heat sink body, electronic component is fixed on the radiating surface 2, perpendicular with circuit board, so only take the pin space at circuit board, 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 to the pin of electronic component clubfoot during practical operation processes, reduce stress to the impact of electronic component, make the assembling of electronic component and circuit board more stable, longer service life.
The present invention 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, and auxiliary fixing member is fixed heat sink body, and good stability can dispel the heat to electronic component good heat dissipation effect.
Above embodiment limits the present invention never in any form, and every other improving and applying that above embodiment is made in the equivalent transformation mode all belongs to protection scope of the present invention.
