Described heat abstractor comprises give vent to anger blower fan and some and described dividing plate ventilating fan one to one, described in give vent to anger on end face that blower fan is fixedly connected on top board and top board offer the venthole be positioned at below blower fan of giving vent to anger;
Blower fan of giving vent to anger described in some is fixedly connected on the lateral surface of same side plate, side plate described in this offer some with ventilating fan air admission hole one to one, described air admission hole and described ventilating fan concentric, described air admission hole is the little shape of outer imperial palace and the internal orifice of air admission hole is positioned at the below of described dividing plate;
The bottom surface of described dividing plate is provided with some radiating fins.
Described heat abstractor also comprises that some symmetry is fixedly connected on secondary ventilating fan on another side plate and extra-air inlet that is some and air admission hole symmetry with ventilating fan.
Filter screen is equipped with in described air admission hole and extra-air inlet.
Described Rear Door offers some horizontally disposed strip through holes, the apical margin of described strip through hole is fixedly connected with the fin of strip, the angle of described fin and described Rear Door is 15-30 °.
Described strip through hole away from described fin aperture, side place be coated with expanded polytetrafluoroethylsealing film.
This case effectively improves by the air admission hole that outer imperial palace is little the flow velocity that ventilating fan is blown into the air-flow in power distribution cabinet, thus effectively improve the heat exchanger effectiveness between air-flow and radiating fin in the mode accelerating wind speed, and then significantly improve the radiating effect of power distribution cabinet entirety.There is delicate structure, easy to use, stability is high and the feature of good heat dissipation effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the right view of Fig. 1;
In figure, 1 is front door, and 2 is Rear Doors, and 20 is fin, and 3 is top boards, and 4 is base plates, and 5 is side plates, and 51 is air admission holes, and 52 is extra-air inlets, and 6 is dividing plates, and 60 is radiating fins, and 7 is heat abstractors, and 71 is blower fans of giving vent to anger, and 72 is ventilating fans, and 73 is secondary ventilating fans.
Embodiment
The utility model as shown in Figure 1-2, described power distribution cabinet comprises front door 1, Rear Door 2, top board 3, base plate 4 and pair of side plates 5, described top board 3 and base plate 4 are all horizontally disposed with, side plate 5 described in a pair is parallel to each other and is fixedly connected between described top board 3 and base plate 4, described front door 1 and Rear Door 2 points are located at the both sides of described side plate 4, and it is all consistent with the height of described side plate 4, described Rear Door 2 is fixedly connected on described in a pair between side plate 5, and the side of described front door 1 is with wherein side plate 5 is hinged;
Described front door 1 and the spacing of Rear Door 2 are less than the width of described base plate 4, make described front door 1 be erected on the end face of described base plate 4; Thus effectively can avoid the phenomenons such as front door appearance after long-time placement is sagging, slippage;
Described power distribution cabinet also comprises some horizontally disposed dividing plates 6, and some described dividing plates 6 to be all fixedly connected on described in a pair between side plate 5;
Described heat abstractor 7 comprises give vent to anger blower fan 71 and some and described dividing plate 6 ventilating fan 72 one to one, described in give vent to anger on end face that blower fan 71 is fixedly connected on top board 3 and top board 3 offer the venthole be positioned at below blower fan 71 of giving vent to anger;
Blower fan 72 of giving vent to anger described in some is fixedly connected on the lateral surface of same side plate 5 (towards power distribution cabinet outside for outward, be interior towards power distribution cabinet inside), side plate 5 described in this offer some with ventilating fan 72 air admission hole 51 one to one, described air admission hole 51 and described ventilating fan 72 concentric, described air admission hole 51 is in the little shape of outer imperial palace and the internal orifice of air admission hole 51 is positioned at the below of described dividing plate;
