Description

A new electric control box with dust-proof and heat-dissipating structure

Technical field:

The utility model relates to the technical field of electrical accessories, in particular to an electric control box with a novel dust-proof and heat-dissipating structure.

Background technique:

The electric control box is the most common electrical accessory in the installation of electrical appliances. Many electrical appliances in the electric control box, such as electronic components, microcomputers, etc., generate a lot of heat during operation. In order to reduce the temperature in the electric control box to ensure normal operation operate.

At present, the usual practice is: to drill a heat dissipation hole on the electric control box shell or install a miniature fan, natural or forced air supply, convection air, exchange and heat dissipation, but it exposes serious drawbacks and defects:

One is that there are many impurities in the air, and the corrosive gas is relatively thick, and the filter on the cooling hole is quickly blocked, which seriously affects the air convection, causing the temperature in the electric control box to rise and the failure rate to increase greatly;

The second is that the humid air outside enters the box, which makes the electrical components damp and easily broken down. Even a computer with self-diagnosis function will automatically stop working;

The third is that particles, dust and corrosive gases in the air can enter the box through the filter and fall on the electrical components. When the humidity reaches a certain level, the insulation performance will decline. At this time, it is easy to short-circuit the electrical circuit, break down the components, and damage the equipment. ; Fourth, for those long-term unattended electrical equipment, the incidence of failure is immeasurable.

Utility model content:

The purpose of the utility model is to provide a new type of electric control box with a dust-proof and heat-dissipating structure in view of the deficiencies in the prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme, which includes a box body, a cover body, and an exhaust fan. The box body is provided with a support plate, the support plate is provided with electrical components, and the upper mounting plate of the electrical components is provided with an exhaust fan. A wiring groove is installed in the lower box body of the machine and electric device, a control panel is also arranged in the box body, and there is a gap between the mounting plate provided with the exhaust fan and the box body.

There is a box door at the front and back of the box body.

The side of the box body is provided with cooling holes.

The control panel is provided with a regulating switch and a working indicator light.

The beneficial effects of the utility model are: an exhaust fan is arranged on the upper mounting plate of the electrical device, a wiring groove is installed in the lower box of the electrical device, a control panel is also arranged in the box, and a fan is provided between the installation plate of the exhaust fan and the box body. There is a gap, when the door is closed, the exhaust fan will allow the air in the box to flow and not directly exchange with the outside air when the box door is closed, because there is a lot of dust in the air, which can effectively prevent dust and dissipate heat at the same time.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a schematic diagram of an exploded structure of the utility model;

Fig. 3 is a schematic structural view of the utility model without the cover.

Detailed ways:

Shown in Fig. 1 to Fig. 3: the utility model comprises box body 1, cover body 2, blower fan 7, and box body 1 is provided with support plate 5, and support plate 5 is provided with electric device, and the upper mounting plate of electric device An exhaust fan 7 is arranged on the top, and a junction groove is installed in the lower box of the electrical device. A control panel 4 is also provided in the box body 1 , and there is a gap 8 between the mounting plate of the exhaust fan 7 and the box body 1 .

A box door 6 is respectively arranged at the front and rear of the box body 1 .

The side of the box body 1 is provided with cooling holes 11 .

The control panel 4 is provided with a regulating switch 41 and a working indicator light 42 .

The working principle of the utility model is as follows: when the box doors 6 on both sides are closed, due to the existence of the gap 8, there is space around the electrical components in the box, and at this time, the exhaust fan 7 works to form a space for air circulation , an air circulation space as shown by the arrow in Figure 3, so that the heat generated by the electrical components can be reduced, and the temperature in the electric control box can be lowered to ensure normal operation. At the same time, the exhaust fan can make the air in the box flow, It does not directly exchange with the outside air, because there is a lot of dust in the air, which can effectively prevent dust and dissipate heat at the same time.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
