Abstract

The invention discloses a distribution box with dust prevention and heat dissipation functions. The distribution box comprises a heat dissipation box and a distribution box fixedly connected to the upper end surface of the heat dissipation box; a power distribution cavity with a rightward opening is formed in the power distribution box; circuit components are placed in the power distribution cavity; and a first sealing plate capable of sealing the right opening of the power distribution cavity is hinged to the right end wall of the power distribution box. According to the distribution box withthe dust prevention and heat dissipation functions, an air suction device can suck external air into the power distribution box when the power distribution box works, so that components in the distribution box are cooled; before entering the power distribution box, the air can be filtered by a filter plate, and therefore, dust and other impurities can be prevented from entering the power distribution box and influencing the working state of the components; and when the working temperature in the power distribution box exceeds a rated value, a refrigerator can be started to cool the power distribution box.

Description

technical field

[0001] The invention relates to the technical field of power distribution housings, in particular to a power distribution box with a built-in dust-proof and heat-dissipating device. Background technique

[0002] The power distribution shell is a large number of parameters in the data. Generally, it is composed of low-voltage forests. The electric housing, the power distribution housing transformed by the rural power grid operates outdoors, it not only receives direct sunlight to generate high temperature, but also generates heat itself during operation, so in the midsummer high temperature season, the temperature inside the box will reach 60 ℃ Above, the temperature at this time greatly exceeds the ambient temperature specified by these electrical appliances, which is not conducive to the operation of electrical appliances. Therefore, a distribution box with a dust-proof heat dissipation device is urgently needed to solve the above problems. improved. Cont...
