Abstract

Disclosed is an automatic control box. A cooling chamber is arranged at the bottom part of a box body of the control box, and a drying barrel is arranged at the top part of the box body; an air inlet of an air suction fan is communicated with the interior of the box body of the control box, and an air outlet of the air suction fan is communicated with the interior of the cooling chamber; a rotating assembly is arranged in a drying barrel, the rotating assembly comprises a rotating barrel and a plurality of rotating heat insulation sheets, the rotating barrel and the drying barrel are coaxially arranged, the space between the drying barrel and the rotating barrel is equally divided into a plurality of independent fan-shaped cavities through using the rotating heat insulation sheets, and drying agent particles are arranged in each fan-shaped cavity; an air outlet of the cooling chamber is communicated with an air inlet of a cold air pipeline, and an air outlet of the cold air pipeline is communicated with the fan-shaped cavities located under the rotating barrel; and the bottom part of the drying barrel communicates with the interior of the box body of the control box through a cold air outlet, and a first filter screen is arranged at the cold air outlet. According to the automatic control box, the rotating cylinder and the rotating heat insulation sheets in the drying barrel are designed to be rotatable, and drying agent particles in different fan-shaped cavities dry the interior of the box body of the control box in turn.

Description

technical field [0001] The invention belongs to the field of electric equipment and relates to an automatic control box, which is particularly suitable for dehumidification and heat dissipation of electronic components inside the electric automatic control box. Background technique [0002] The automation control box is widely used in various industries such as instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, and precision machinery. Since the outer casing of the automation control box is generally made of metal, various electrical components are installed inside. Since the electrical components will continuously release heat during work, it is necessary to dissipate heat inside the electrical automation control box; at the same time, due to changes in the ambient temperature, it is also necessary to consider The effect of condensation on electrical components. [0003] In the prior art, cooling holes are provided on th...
