Background technique
Power capacitor is the capacitor for electric system and electrical equipment, is widely used in factory's distribution system, occupies
The fields such as people's cell distribution system, municipal commercial building, traffic tunnel distribution system, case change, complete cabinet, distributed board outdoor.Electricity
Under power capacitor working condition, because the operation of internal unit can generate a certain amount of heat, if cannot distribute in time, heat exists
Power capacitor building up inside easily causes the scaling loss of power capacitor device.Meanwhile capacitor can generate make an uproar at work
Sound influences environment.For this reason, it may be necessary to propose a kind of high efficiency and heat radiation and can to reduce the power capacitor of noise.
Summary of the invention
The utility model is based on the above background, it is therefore intended that solves existing power capacitor poor radiation, noise is big to ask
Topic proposes a kind of power capacitor with heat dissipation decrease of noise functions.
The utility model is achieved by the following technical solution：A kind of heat dissipation noise reducing type power capacitor, including shell,
Capacitor core, lead terminal, it is characterised in that：Multiple block-like protrusions are equipped on the inside of the housing sidewall, the block-like protrusions are
Netted cube, the block-like protrusions are distributed in housing central section and lower part, and the case top center is equipped with top portion ventilation mouth, shell
Body sidewall upper end is symmetrically arranged with two upper end ventilation openings, and housing sidewall lower end is also symmetrically arranged with two lower end ventilation openings, the shell
Body bottom inside is equipped with wind-guiding block, and two choke lids are additionally provided with outside the shell, and the choke lid setting is divulged information two upper ends
Outside mouthful.
Further, the top portion ventilation mouth, upper end ventilation opening, be equipped with Air Filter in the ventilation opening of lower end.
Further, the top portion ventilation mouth is equipped with dust cover.
Further, the wind-guiding block is quadrangle taper.
Compared with prior art, the utility model has the advantages that：
1, by setting ventilation opening, enter capacitor internal conducive to outside air.
2, by the way that block-like protrusions are arranged on the inner wall of the housing, air is made to form turbulent flow in flow process, to enhance air
Heat exchange between inside.
3, block-like protrusions setting reticulates, and densely arranged on the inner wall of the housing, can be effectively in the absorption capacitor course of work
The noise of generation.
4, hot-air has the tendency that self-heating is walked on the net, and block-like protrusions are distributed at lower part of the housing 2/3rds, above three points
One of be not provided with, be conducive to hot-air from the ventilation opening of top and sidewall upper be discharged.
5, the wind-guiding block of housing bottom is conducive to up flow from the air that shell lower end ventilation opening enters.
6, on ventilation opening Air Filter and dust cover setting, can effectively avoid dust and enter capacitor internal.
In short, the utility model structure is simple, both the service life of capacitor can be extended, and can be greatly with high efficiency and heat radiation
Capacitor work noise is reduced, environment is protected.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
As shown in Figure 1 and Figure 2, a kind of heat dissipation noise reducing type power capacitor, including shell 1, capacitor core 2, lead terminal 6,
It is characterized in that：1 inside sidewalls of shell are equipped with multiple block-like protrusions 4, and the block-like protrusions 4 are netted cube, described
Block-like protrusions 4 are distributed in the middle part of shell 1 and lower part, and 1 center of top of shell is equipped with top portion ventilation mouth 303, on 1 side wall of shell
End is symmetrically arranged with two upper end ventilation openings 301, and 1 side wall lower ends of shell are also symmetrically arranged with two lower end ventilation openings 302, the shell
1 bottom inside is equipped with wind-guiding block 5, and two choke lids 32 are additionally provided with outside the shell 1, and the choke lid 32 is arranged two upper ends
Outside ventilation opening 301.
In the present embodiment, the top portion ventilation mouth 303, upper end ventilation opening 301, be equipped in lower end ventilation opening 302 it is dust-proof
Net 31.
In the present embodiment, the top portion ventilation mouth 303 is equipped with dust cover 7.
In the present embodiment, the wind-guiding block 5 is quadrangle taper.
The heat dissipation noise reducing type power capacitor generates heat when working, and heats inner air, since hot-air has nature
The trend up walked, as the temperature rises, bottom will form negative pressure in capacitor, and external air will be 1 two from shell
Lower end ventilation opening 302 enters, and the air-flow of rising is formed under the action of wind-guiding block 5, air-flow takes away battery while up walking
The heat of core 2, as the temperature rises, hot-air will continue to up walk, and continue the heat for taking away battery 2, while by shell 1
The interference of block-like protrusions 4 of inner wall forms turbulent flow, enhances the heat exchange of inside air.When hot-air rises to top, due to
There is no the interference of block-like protrusions 4, can be successfully discharged from two upper end ventilation openings 301 and top portion ventilation mouth 303, to play
The effect of radiating and cooling.Simultaneously as the block-like protrusions 4 of 1 inner wall of shell are netted cube structure, and densely arranged in shell
On 1, can effectively absorption capacitor work when the noise that generates, to play the role of noise reduction.
