Compared with prior art, the beneficial effects of the invention are as follows：The present invention passes through electric by stepping in the setting of cabinet lower part
The cooling piece component of machine driving, cooperation baffle, the first deflector, the second deflector and wind shield etc., is realized to power distribution cabinet inside
The adjusting of humiture, simple and compact for structure, the factory floor for being suitable for various complex working conditions uses.
Specifically：The cooling piece component has four kinds of different working conditions：
When temperature sensor measured temperature be higher than desired temperature, and humidity sensor measure humidity be less than humidity set point
When, it is only necessary to natural wind is blown into cabinet to cool down, and semiconductor chilling plate need not start work, temperature compared with
Then increase fan input power when high, improves rotating speed；In the state, the semiconductor chilling plate is in heeling condition, is conducive to
Upper fan and the wind of lower fan blowout can be up blown into cabinet；In addition, upper fan and the air temperature of lower fan blowout are high
In 20 DEG C, the connection strut keeps open configuration, props up and turns over plywood so that turns over plywood and is kept upright state；It is blown by lower fan
The wind entered acts on front wind screen, and the adsorption capacity of permanent magnet can not overcome wind action power so that front wind screen is blown afloat, warp
Cabinet top is flowed to through radiation aluminium seat by cooling piece assembly portion major part wind, the wind after shunting can not overcome permanent magnet to keep out the wind to after
The adsorption capacity of plate, rear wind-break panels are kept closed, and there is no need to additional driving parts to prevent the wind of lower fan blowout straight
Connect lower exhausting plate direction blowout to the right.
When temperature sensor measured temperature be higher than desired temperature, and humidity sensor measure humidity be higher than humidity set point
When, the vapor in air is condensed into water using the condensation aluminium seat on cooling piece huyashi-chuuka (cold chinese-style noodles), so that enter the sky in cabinet
Gas is more dry, and since air is by the cooling of condensation aluminium seat, temperature is relatively low, thus in the working condition on fan input
Power may be set to smaller value（Such as 1/3 when wind speed being made to be the first working method）Although the cold wind unit interval of low temperature
Interior intake is few, but also disclosure satisfy that heat dissipation needs；The air temperature that condensed aluminium seat is blown on connection strut is less than 5 DEG C, institute
It states connection strut to shrink under cold wind effect, turns over plywood and turn over conjunction downwards, it is right with first deflector to turn over plywood movable end upper edge
End upper edge sealing offsets, and cabinet is flowed out to by each upper flow-guiding mouth along flow-guiding channel by the cold wind of the condensed aluminium seat blowout of upper fan
It is interior；In addition, in the working condition, lower fan cools down the radiation aluminium seat being below, corresponding permanent magnet pair
Front wind screen, rear wind-break panels adsorption capacity the wind of lower fan can not be overcome respectively to the active force of front wind screen, rear wind-break panels, make
Obtain front wind screen, rear wind-break panels are stirred upwards under the blowing of lower fan, lower exhausting plate blowout of the hot-air on the right side of cabinet.
When temperature sensor measured temperature be less than desired temperature, and humidity sensor measure humidity be less than humidity set point
When, in order to make the electrical equipment in power distribution cabinet be operated in stable state, it may be selected to heat the air in cabinet, lead at this time
The radiation aluminium seat crossed in semiconductor chilling plate heating surface is heated to entering the air in cabinet, and connection is blown to through radiation aluminium seat
Air temperature on strut is higher than 20 DEG C, and the connection strut keeps open configuration, props up and turns over plywood so that turns over plywood and be kept upright
State, and lower fan heats up to condensation aluminium seat, avoiding condensation, aluminium seat temperature is too low that condensed moisture is caused to freeze.
When temperature sensor measured temperature be less than desired temperature, and humidity sensor measure humidity be higher than humidity set point
When, by the way that semiconductor chilling plate to be vertically arranged, so that the air that fan, lower fan are blown into is first passed through condensation aluminium seat condensation of water, connect
It more dry air using after the heating of radiation aluminium seat to enter in cabinet, since semiconductor chilling plate is integrally fever
（Since a part of heat of heating surface is passed over from huyashi-chuuka (cold chinese-style noodles), a part is the heat of electric energy conversion）, therefore in dry air
While air can be heated, keep distribution in-cabinet temperature stabilization.In the working condition, the input of upper fan is just
Normal power, lower fan are in shutdown status；The air temperature that first condensed aluminium seat is blown to through radiation aluminium seat on connection strut again is higher than
20 DEG C, the connection strut keeps open configuration, props up and turns over plywood so that turns over plywood and is kept upright state, is blown by upper fan
Wind via condensation aluminium seat cool-down dehumidification, then cabinet top is flowed into after being heated up by radiation aluminium seat, the wind of part escape can not overcome
To the adsorption capacity of front wind screen, rear wind-break panels, front wind screen, rear wind-break panels are all kept closed permanent magnet；Without additional
Driving part prevents the lower exhausting plate direction blowout of the wind of upper fan blowout directly to the right.
