Abstract
The utility model discloses a radiator for a power device, which comprises a radiator body including an attaching surface, a bottom surface and radiating fins. The radiating fins are fixed on the back face of the attaching surface, and an included angle formed by the attaching surface and the bottom surface is smaller than 90 degrees, thereby effectively solving the problem of the height of the radiator under the condition that the height of a power source is limited, enlarging radiating area, occupying small area of a printed circuit board (PCB) and facilitating assembly and disassembly of the power device. In addition, the whole radiator does not need to be disassembled in maintenance, an installation portion on an installation joint surface can be conveniently disassembled from the whole radiator, a device pin is formed to be smaller than 90 degrees, and the damage to the pin is avoided.
Description
Technical field
The utility model relates to a kind of radiator, particularly relates to a kind of radiator that is used to distribute the heat that power device produces.
Background technology
Usually, be installed on the circuit board in the various electronic installations many electronic devices are housed, these electronic devices are supplied power by power supply, and the some of them electronic device can produce a large amount of heat in the course of the work; Especially the power device on the circuit board in order to prevent the too high components and parts that burn out of temperature, need add radiator, and existing power device is (like metal-oxide-semiconductor; Rectifying tube) installation method on radiator, general vertical installation or the horizontal mounting means of adopting, vertical mounting means is as shown in Figure 1; The power device installed surface is vertical with pcb board, and area of dissipation is big, under the situation that " H " highly do not required, is the most frequently used; But,, can't use if the power supply requirement for height is lower because vertical the installation receives limitation in height; General employing this moment horizontal mounting means as shown in Figure 2, the power device installed surface is parallel with pcb board, and level is installed and can be solved because of the low problem of power supply height; But installation difficulty is big, and area of dissipation is little, and it is big to take plane space.And operation inconvenience is sometimes possibly by specific purpose tool, if there are a plurality of power devices just to be difficult to operation more side by side; Simultaneously since on year-on-year basis area of dissipation reduce, need take bigger PCB space, be unfavorable for the volume miniaturization; When being connected power device on the pcb board, if the device pin moulding be 90 ° then fracture easily, cause pin damage; If less than 90 °, then can take more PCB space.There is the inconvenient problem of maintenance simultaneously in two kinds of mounting meanss, and the power device of dismantling needs to pull down radiator (if having a plurality of devices also will remove together on the same radiator) earlier, pulls down corresponding power device again.
Summary of the invention
The utility model technical problem to be solved is: the deficiency that remedies prior art; A kind of radiator that is used for power device is proposed; Solved the radiator height problem under the situation of the height-limited system of power supply, increased area of dissipation simultaneously, power device is convenient to dismounting; Increase operating efficiency, convenient for maintaining.
The technical problem of the utility model solves through following technical scheme:
A kind of radiator that is used for power device comprises radiator body, and said radiator body comprises the face of mounting, bottom surface and fin; Said fin is fixed on the said back side that mounts face, and the said angle that mounts face and said bottom surface is less than 90 °.
Preferably, said fin is dentation and is spaced, and parallel with said bottom surface.
Preferably, the said angle that mounts face and said bottom surface is 30 ° ~ 75 °.
Preferably, the said face of mounting is provided with screwed hole or through hole,
Preferably, said bottom surface is provided with screwed hole or through hole.
Preferably, the surface of said fin also is provided with ripple glaze.
The beneficial effect of the utility model and prior art contrast is: efficiently solve the radiator height problem under the situation of the height-limited system of power supply; Increased area of dissipation, it is less to take the PCB area, more helps the dismounting power device simultaneously; When maintenance, need not pull down entire radiator; Just can unload the installation portion of installing on the binding face on the complete machine very easily, and the device pin moulding can not cause the pin damage less than 90 °.

In other preferred embodiments, the mode that power device is installed on the face of mounting can also be jump ring, press strip etc.
In other preferred embodiments, also can adopt the riveting pin to be welded on the pcb board 3 in radiator.
Adopt the radiator of technique scheme, power device is installed on the radiator, and when being connected with pcb board 3, the pin moulding angle [alpha] of power device can not cause pin to damage less than 90 °.
Wherein mounting face 11 can freely select according to height " H " requirement with the angle of bottom surface 13; The space width of fin 14, transverse tooth thickness degree can be selected according to concrete environment for use (like natural heat dissipation, fan forced heat radiation etc.), can also increase some ripple glazes on the surface of fin for increasing area of dissipation.
More than the power device of arbitrary embodiment can be the electronic device that metal-oxide-semiconductor, rectifying tube, triode etc. can generate heat in the course of the work.
