Abstract

The utility model relates to an air-cooled electric control box, which comprises a box body and a box door. Electrical components are arranged in the box body, a fan is arranged in the middle of the bottom plate of the box body, and the inside of the box body is arranged on the back plate of the box body. There is a partition, and the partition forms an air duct and a device cavity in the box. The air duct is located around the device cavity, and the fan is located at one end of the air duct. Ventilation holes are arranged on the partition adjacent to the air duct and the device cavity. The device cavity There are air outlet holes on the inner back panel. The air duct is arranged in the box, which increases the flow velocity of the air in the box, and makes the air blow directly on the electrical components, which improves the efficiency of air cooling, so that the heat dissipation effect is better.

Description

Air-cooled electric control box

technical field

The utility model relates to an electric control box adopting air cooling.

Background technique

Because many electrical components and lines are placed in the electric control box, the temperature inside the box will be high, but some electrical components will be affected at high temperatures, so the electric control box needs to be cooled. At present, fans are mostly installed in the electric control box to dissipate heat. However, due to the large internal space of the electric control box, the heat dissipation effect is not ideal.

Utility model content

The technical problem to be solved by the utility model is to provide an air-cooled electric control box with better heat dissipation effect.

In order to solve the above problems, the technical solution adopted by the utility model is: the air-cooled electric control box includes a box body and a box door, electrical components are arranged in the box body, a fan is arranged in the middle of the bottom plate of the box body, and the inside of the box body A partition is arranged on the back plate of the box, and the partition forms an air duct and a device cavity in the box. The air duct is located around the device cavity, and the fan is located at one end of the air duct. Ventilation holes are arranged on the top, and air outlet holes are arranged on the inner back plate of the device cavity.

As a preferred solution, the ventilation hole faces one side of the electrical component, and the air outlet hole is located on the other side of the electrical component opposite to the ventilation hole.

The beneficial effects of the utility model are: the above-mentioned air-cooled electric control box is provided with an air duct in the box, which increases the flow rate of the air body in the box, and makes the air body directly blow on the electrical components, which improves the air-cooling efficiency. Efficiency for better heat dissipation.

detailed description

The air-cooled electric control box described in the present utility model will be further described in detail through specific embodiments below.

As shown in Figure 1, the air-cooled electric control box includes a box body 1 and a box door 2. Electrical components 3 are arranged in the box body 1, and a fan 4 is arranged in the middle of the bottom plate of the box body 1. The inside of the box body 1 A partition plate 5 is arranged on the back plate of the box body 1, and the partition plate 5 forms an air duct 6 and a device chamber 7 in the cabinet body 1, the air duct 6 is located around the device chamber 7, and the fan 4 is located at one end of the air duct 6, Ventilation holes 8 are provided on the partition plate 5 adjacent to the air channel 6 and the device chamber 7 , and air outlet holes 9 are provided on the inner back plate of the device chamber 7 . The ventilation hole 8 faces one side of the electrical component 3 , and the air outlet hole 9 is located on the other side of the electrical component 3 opposite to the ventilation hole 8 .

The working principle of the utility model is: the above-mentioned air-cooled electric control box, when in use, blows the inside of the air duct 6 through the fan 4, and the air duct 6 in the box body 1 increases the air flow in the box body 1. The body flow rate is so that the air body directly blows on the electrical components 3 after passing through the ventilation holes 8, and then discharges the box body 1 from the air outlet holes 9, which improves the efficiency of air cooling and thus has a better heat dissipation effect.
