Description

Technical Field

[0001] The utility model relates to the field of electric control cabinets, in particular to an electric control cabinet with a dustproof function. Background Art

[0002] The electric control box contains one or more low-voltage switchgear and related control, measurement, signal, protection, regulation and other equipment, and is completely assembled together by the manufacturer using structural components. Normally, the electrical components of the electric control box will generate heat when it is running, so the inside of the electric control box needs to be cooled. During the heat dissipation process, the problem of dust accumulation in the electric control box after the heat dissipation time needs to be solved.

[0003] At present, a Chinese patent application with publication number CN214958220U and publication date November 30, 2021 proposes a rat-proof and dust-proof device for a floor-standing electrical control box, including: a box body, a box door, an embedded hole, a drawer box body, a handle, a protrusion, an adjustment component, a heat dissipation component and a blocking component. The box door is arranged on the outer wall of the box body, the blocking component is arranged on the bottom wall of the box body, the embedded hole is embedded in the side wall of the box body, a protrusion is provided on the top wall and the bottom wall on one side of the embedded hole, the drawer box body is arranged in the embedded hole, the handle is arranged on the outer wall of the drawer box body, the adjustment component is arranged on the outer wall of the box body, and the heat dissipation component is arranged on the drawer box body.

[0004] With regard to the above-mentioned related technologies, the inventor believes that the heat dissipation method of ordinary control cabinets after installing electrical components is to filter through a filter and then blow directly to the electrical components through a cooling fan. After a long time, the filtering effect of the filter is reduced, resulting in reduced heat dissipation effect, and dust is more likely to enter the control cabinet, causing pollution to the electrical components. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an electrical control cabinet with dustproof function.

[0006] The utility model provides an electrical control cabinet with dustproof function, which adopts the following technical solutions:

[0007] An electrical control cabinet with a dustproof function comprises an outer box, a box door, and a dustproof mechanism, wherein the box door is mounted on the outer box, the dustproof mechanism comprises a mounting assembly and a heat dissipation assembly, the mounting assembly comprises a cabinet body and a mounting plate, the cabinet body is mounted in the outer box, a plurality of mounting plates are provided, and all mounting plates are mounted in the cabinet body, the heat dissipation assembly comprises a first heat conducting plate, a second heat conducting plate, and a third heat conducting plate, wherein the second heat conducting plate is mounted on the cabinet body near one end of the mounting plate, the first heat conducting plate is mounted on the second heat conducting plate in the cabinet body, and the third heat conducting plate is mounted on the second heat conducting plate outside the cabinet body.

[0008] By adopting the above technical solution, when the control cabinet needs to be cooled, the electrical components are installed on the mounting plate so that the electrical components are in contact with the first heat conducting plate. Then, when the electrical components are working, the heat generated by the electrical components is transferred to the outside of the cabinet through the first heat conducting plate, the second heat conducting plate and the third heat conducting plate, thereby achieving heat dissipation of the electrical components and reducing the possibility of external dust entering the cabinet, thereby effectively reducing the interference of dust on the electrical components.

[0009] Optionally, the heat dissipation assembly also includes a heat dissipation fan, an exhaust fan and a fixed plate. The outer box is provided with an air inlet and an air outlet.

[0011] Optionally, the heat dissipation assembly further includes a heat sink, a plurality of heat sinks are provided, and all heat sinks are mounted on the third heat conducting plate.

[0012] By adopting the above technical solution, the contact area between the heat sink and the cold air emitted by the heat dissipation fan is increased, thereby further improving the heat dissipation effect.

[0016] By adopting the above technical solution and providing a thermally conductive soft layer, during the installation of electrical components, the thermally conductive soft layer can have a more comprehensive contact surface with the electrical components, reducing the gap between the contacts, improving the thermal conductivity, and thus further improving the heat dissipation effect.

[0017] Optionally, the heat dissipation assembly further includes a spring, one end of which is mounted on the cabinet, and the other end of which is mounted on the third heat conduction plate.

[0018] By adopting the above technical solution and setting the spring, it is achieved that during the installation of the electrical component, the contact surface of the electrical component can be directly squeezed more tightly with the thermally conductive soft layer, thereby further improving the thermal conductivity effect.

[0020] By adopting the above technical solution and setting a temperature monitor, the temperature inside the outer box can be detected. When the temperature is too high, the rotation speeds of the cooling fan, exhaust fan and circulation fan can be increased to increase the ventilation volume and improve the heat dissipation effect. When the temperature of the outer box is low, the rotation speeds of the cooling fan, exhaust fan and circulation fan can be reduced to save electricity consumption and energy.

[0021] Optionally, the electrical control cabinet with dustproof function also includes a handle and an observation window, and the handle and the observation window are both installed on the box door. The heat dissipation assembly also includes a card plate, a filter screen and a ventilation screen. The card plate is installed on the outer box near the air inlet, the filter screen is slidably installed on the card plate, and the ventilation screen is installed on the outer box at one end of the air outlet.

[0022] By adopting the above technical solution, the filter is slidably mounted on the card plate, so that when the filter needs to be replaced, it can be replaced by pulling out the filter, making the replacement process more convenient.

[0024] 1. When the control cabinet needs to be cooled, the electrical components are installed on the mounting plate so that the electrical components are in contact with the first heat conducting plate. When the electrical components are working, the heat generated by the electrical components is transferred to the outside of the cabinet through the first heat conducting plate, the second heat conducting plate and the third heat conducting plate, so as to achieve the heat dissipation of the electrical components and the effect of isolating the electrical components from the heat dissipation duct. At the same time, the possibility of external dust entering the cabinet is reduced, and the interference of dust on the electrical components is effectively reduced.
