Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a dust removal and heat dissipation power distribution cabinet. Background Art

[0002] The distribution cabinets refer to the final equipment of the distribution system, such as the power distribution cabinet, lighting distribution cabinet, metering cabinet, etc. The distribution cabinets are used in occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits. They distribute the electric energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load, and distribution cabinets are also commonly found in factory workshops with a lot of dust and high temperature.

[0003] During use, the existing distribution cabinet only has heat dissipation holes on the outside of the distribution cabinet to dissipate heat. After the electronic components inside the distribution cabinet are installed, the gas flow inside the distribution cabinet is poor, and the heat generated by the electronic components inside the distribution cabinet moves upward, which makes it inconvenient to dissipate the heat inside the distribution cabinet through the heat dissipation holes. There is also a lack of protection devices for the heat dissipation holes, which makes it easier for dust to enter the distribution cabinet and accumulate when working in a dusty workshop, thereby damaging the electronic components. Therefore, a dust removal and heat dissipation distribution cabinet is proposed to solve the above problems. Utility Model Content

[0004] 1. Technical issues to be resolved

When the dust concentration is large, the heat dissipation holes are sealed by a sealing block to prevent dust from entering the interior of the distribution cabinet, and the distribution cabinet can also be protected after shutdown. The upper and lower exhaust fans and suction fans enhance the air circulation inside the distribution cabinet, which solves the problem that the existing distribution cabinet only has heat dissipation holes on the outside of the distribution cabinet for heat dissipation during use, and after the electronic components inside the distribution cabinet are installed, the gas fluidity inside the distribution cabinet is poor, and the heat generated by the electronic components inside the distribution cabinet moves upward, resulting in inconvenience in dissipating the heat inside the distribution cabinet through the heat dissipation holes, and there is a lack of a device to protect the heat dissipation holes, which makes it easier for dust to enter the interior of the distribution cabinet and cause accumulation when working in a dusty workshop, thereby damaging the electronic components.
