Abstract
The utility model discloses a kind of reliable low-noise electrical capacitor, including shell, it is equipped with sound-absorbing lid at the top and bottom of shell, sound-absorbing material is filled in the sound-absorbing lid, the side of shell is equipped with several cooling fins, and the cooling fin is equipped with aperture.It is provided with the cooling fin of aperture using the side in shell, increases the contact area of shell and air, improves radiating efficiency, avoids the case where causing rate of heat dissipation to decline because of the top and bottom of shell setting sound-absorbing lid.The invention can be used for capacitor technology field.
Description
Technical field
The utility model relates to capacitor technology field, in particular to a kind of reliable low-noise electrical capacitor.
Background technique
Occurs a kind of power capacitor of low noise on the market now, structure generally comprises: the top and bottom of capacitor
It is covered with sound-absorbing material, the energy of other forms is converted by the vibration of power capacitor using sound-absorbing material, to reduce electricity
The noise of container.
But the power capacitor of existing low noise, the undesirable feelings of heat dissipation are easy to appear due to covering sound-absorbing material
Condition.
Utility model content
The purpose of this utility model is: providing one kind reliably, not only can guarantee good heat radiating but also the electric power electricity of energy low noise
Container.
The solution that the utility model solves its technical problem is: a kind of reliable low-noise electrical capacitor, including
Shell is equipped with sound-absorbing lid at the top and bottom of shell, and sound-absorbing material is filled in the sound-absorbing lid, and the side of shell is equipped with several
Cooling fin, the cooling fin are equipped with aperture.
Further, the cooling fin and the shell are integrally formed.
Further, the sound-absorbing material with a thickness of 20-50mm.
The beneficial effects of the utility model are: being provided with the cooling fin of aperture using the side in shell, increase outer
The contact area of shell and air improves radiating efficiency, avoids and causes to radiate because sound-absorbing lid is arranged for the top and bottom of shell
The case where rate declines.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.Obviously, described attached drawing is a part of the embodiment of the utility model, rather than complete
Portion's embodiment, those skilled in the art without creative efforts, can also be obtained according to these attached drawings it
His design scheme and attached drawing.
Fig. 1 is the structural schematic diagram of the invention power capacitor.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, Lai Zucheng more preferably coupling structure.Each technology in the invention is special
Sign, can be with combination of interactions under the premise of not conflicting conflict.
Embodiment 1, with reference to Fig. 1, a kind of reliable low-noise electrical capacitor, including shell 1, the top and bottom of shell 1
Portion is equipped with sound-absorbing lid, and sound-absorbing material is filled in the sound-absorbing lid, and the side of shell is equipped with several cooling fins 2, the cooling fin 2
It is equipped with aperture 21.
Using the cooling fin 2 for being provided with aperture 21 in the side of shell 1, the contact area of shell 1 Yu air is increased,
Radiating efficiency is improved, the case where causing rate of heat dissipation to decline because of the top and bottom of shell 1 setting sound-absorbing lid is avoided.So that low
Noise power capacitor guarantees heat dissipation while ensuring low noise.
As advanced optimizing for above embodiment, the cooling fin 2 is integrally formed with the shell 1.
As advanced optimizing for above embodiment, the sound-absorbing material with a thickness of 20-50mm.
The better embodiment of the utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make various equivalent changes without departing from the spirit of the present invention
Type or replacement, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
