A kind of radiator structure of magnetic suspension bearing multiplex power amplifier, as depicted in figs. 1 and 2, including both ends open
Radiate bellows 1, and the power device 3 in PCB circuit board 2 to be radiated protrudes into heat dissipation inner bellows, and corresponding PCB circuit board is fixed
In the outer wall of heat dissipation bellows side plate 4；
The heat dissipation inner bellows correspond to and are equipped with upper radiator 5 above power device, corresponding power device lower section is equipped with master
Radiator 6；By connector 7, upper radiator, power device and main radiator are connected and fixed integrally, on heat dissipation bellows top
It is correspondingly connected with part on plate and sets through-hole 8, connector can be protruded into connector via through holes when the assembly is complete using screw
Into heat dissipation bellows, it is attached fixation；
The upper radiator includes upper matrix part 9 and upper cooling fin 10, upper matrix lower surface and power device upper surface
Fitting；The main radiator includes main matrix part 11 and main cooling fin 12, main matrix lower surface and power device following table face paste
It closes；
There are windward chamber 13 between the upper radiator and the top plate for the bellows that radiate, and each abutting fins of upper radiator
Between radiating groove 14 be connected to windward chamber；There are leeward chambers 15 between the main radiator and the bottom plate for the bellows that radiate, and
Radiating groove between each blade of main radiator is connected to leeward chamber.
In practical radiation processes, fan is arranged in corresponding heat dissipation bellows side opening, is dried using fan into bellows.
Such structure design, has been effectively ensured the heat dissipation effect of radiator, and the heat absorbed by radiator is through radiating groove and accordingly
The intracavitary cold wind of wind is taken away, and wind area excessively is big, good heat dissipation effect.
Above-mentioned upper radiator two sides by fixed from the first screw 16 for penetrating of heat dissipation bellows side plate, first screw according to
It is secondary to pass through PCB circuit board, side plate, PCB circuit board, side plate and upper radiator are fixed together.
Above-mentioned main radiator two sides by fixed from the second screw 17 for penetrating of heat dissipation bellows side plate, second screw according to
It is secondary to pass through PCB circuit board, side plate, PCB circuit board, side plate and main radiator are fixed together.
What is be spaced between above-mentioned main cooling fin and radiation air bottom plate is equipped with cushion block, since upper radiator passes through the first screw
Fixed with corresponding construction part, main radiator is fixed by the second screw and corresponding construction part, in addition connector by upper radiator,
Power device and main radiator are fixed, and overall stability is good, and further through the supporting role of set cushion block, it is more reliable
It ensure that the stability of structure.
Positioning column 18, PCB circuit board and heat dissipation bellows side plate are equipped between the side plate and PCB circuit board of above-mentioned heat dissipation bellows
Between ventilation gap 19 formed by positioning column interval.PCB circuit board and side sheet room have also sufficiently reserved the space of ventilation and heat, really
Heat dissipation effect is protected.Above-mentioned the first screw, the second screw are also possible to that inner bellows are corresponding dissipates across positioning column and heat dissipation
Hot device connection.
Above-mentioned heat dissipation bellows both side plate outer surface is respectively provided with the installation position of installation PCB circuit board.Here installation
Position refers to the space that can install PCB circuit board to be radiated, and can be above-mentioned positioning column, is also possible to that wiring board is kept for pacify
The space of dress.That is, heat dissipation bellows two sides can effectively install PCB circuit board, and the power device on the heat sink of two sides
Part can be extend into heat dissipation bellows by the via hole of side plate, arranged for structure, provided more conveniences.
Above-mentioned heat dissipation bellows use metal material, and the two sides of the upper radiator and main radiator are fitted in radiation air
The inner wall of case side plate enhances thermally conductive function, better heat-radiation effect.
Since heat dissipation air duct can completely blow the wind that fan is blown out on a heat sink, if not radiating air duct, wind
The wind of fan blowout will blow to entire cabinet, can not completely concentrate on a heat sink.There is heat dissipation air duct will be by wind collection
On middle guide radiator, the reduction of air quantity not will cause, improve the efficiency that wind takes away heat on radiator.
The invention is reasonable in design, breaks conventional power devices and his device on one face and power device
The structure on the assist side that can only arrange both sides, each power device can only be close to side cooling fin by screw fastening carry out it is scattered
Heat, heat-sinking capability all close to radiator, is improved in the power device upper and lower surfaces of this structure, and the multichannel of side is only with installation
No more than 3 screw can be by pressing power, and realizes common heat dissipation up and down.Improve radiating efficiency, saving of work and time.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope within.
