Abstract
The utility model relates to an electrical cabinet suitable for heat dissipation of a power electronic device, and is characterized in that: a cabinet body is provided with a device chamber used for installing the power electronic device therein, the device chamber is provided with an air inlet at a sidewall of the cabinet body, the cabinet body is also provided with a fan chamber used for installing a fan therein, the device chamber is separated from the fan chamber through a separator plate, the separator plate is provided with an air inlet of the fan, the fan is arranged over against the air inlet of the fan, an air outlet of the fan is arranged at a top of the fan chamber. The electrical cabinet of the utility model has the beneficial effects that: the electrical cabinet is divided into two portions through the separator plate, one portion is used for installing the power electronic device, the other portion is a heat dissipation portion used for installing the fan, the separator plate can avoid convection and enables the air to be smoothly discharged from the air outlet; the centrifugal fan is arranged inside the cabinet, thus noise outside the cabinet can be effectively reduced, and danger for injuring people can be reduced.
Description
Technical field
The utility model relates to a kind of regulator cubicle that wind-cooling heat dissipating is provided for power electronic device.
Background technology
Along with the development of device for high-power power electronic, the heat radiation of high power device becomes an important problem, and uses heat radiation to mainly contain liquid cooling and air-cooled dual mode at present.Wherein liquid cooling is used complicacy because cost is high, only under the big situation of heat radiation density, uses.When using wind-cooling heat dissipating, need to use blower fan, when high-power heat radiation, just brought new problem like this, fan noise causes the cabinet noise bigger, and in the more place of personnel, noise pollution is big.When existing power cabinet uses centrifugal blower to dispel the heat, all centrifugal blower is installed in outside the cabinet.Adopt this mounting means, exist centrifugal fan noise big, and when carrying out wiring easy bump player.
The utility model content
The purpose of the utility model provides a kind of regulator cubicle that is suitable for the power electronic device heat radiation, in order to solve the problem that existing mounting means noise is big, be prone to hurt sb.'s feelings.
For realizing above-mentioned purpose, the scheme of the utility model is: a kind of regulator cubicle that is suitable for the power electronic device heat radiation is provided with the device chamber that is used for the installation power electronic device in the cabinet; The device chamber offers fresh air inlet on a sidewall of cabinet; Also be provided with the fan house that blower fan is installed in the cabinet, device chamber and fan house separate through a dividing plate, offer the air inlet of blower fan on the dividing plate; Said blower fan is provided with over against said blower fan mouth, and the air outlet of said blower fan is located at the top of fan house.
Said blower fan is arranged in the pipeline, and the inlet of this pipeline connects air inlet, and outlet connects the air outlet of said blower fan.
Adopt this mode, with separated into two parts in the regulator cubicle, a part is used for the installation power electronic device through dividing plate, and another part is for installing the radiator portion of blower fan, and dividing plate can be avoided convection current, and wind is discharged from air outlet smoothly.Because centrifugal blower is installed in the cabinet, can effectively reduce cabinet external noise and the danger that reduces the personnel that damage.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the fan outlet sketch map;
Fig. 3 is the fresh air inlet sketch map;
Fig. 4 is the regulator cubicle sketch map of band pipeline configuration.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Like Fig. 1,2,3, a kind of regulator cubicle that is suitable for the power electronic device heat radiation shown in 4; Comprise cabinet; Cabinet top is radiator portion 6, and it is divided into two parts: be used for the device chamber 8 of installation power electronic device 1, device chamber 8 offers fresh air inlet 3 on a sidewall (being front panel in the present embodiment) of cabinet; Like Fig. 3, fresh air inlet 3 is the grid hole.Also be provided with the fan house 7 that blower fan 5 is installed in the cabinet, device chamber 7 separates through a dividing plate 2 with fan house 8, offers the air inlet of blower fan on the dividing plate 2, and blower fan 5 is provided with over against the blower fan mouth, and the air outlet 4 of blower fan is located at the top of fan house 7.In the present embodiment, from the anterior air intake of cabinet, from the air-out of cabinet top.So just cooling fan is installed in the cabinet noise of minimizing cooling fan that can be successful and the injury that is reduced in cabinet back workmen.
As other execution modes, blower fan is arranged in the pipeline 10, the inlet of this pipeline 10 connects air inlet, and outlet connects the air outlet 4 of said blower fan.
Claims (2)
1. a regulator cubicle that is suitable for the power electronic device heat radiation comprises cabinet, is provided with the device chamber that is used for the installation power electronic device in the cabinet; The device chamber offers fresh air inlet on a sidewall of cabinet, it is characterized in that, also is provided with the fan house that blower fan is installed in the cabinet; Device chamber and fan house separate through a dividing plate; Offer the air inlet of blower fan on the dividing plate, said blower fan is provided with over against said blower fan mouth, and the air outlet of said blower fan is located at the top of fan house.
2. a kind of regulator cubicle that is suitable for the power electronic device heat radiation according to claim 1 is characterized in that said blower fan is arranged in the pipeline, and the inlet of this pipeline connects air inlet, and outlet connects the air outlet of said blower fan.
