Low-voltage distribution cabinet with heat dissipation and dust prevention function

Abstract

The invention discloses a low-voltage distribution cabinet with a heat dissipation and dust prevention function. The low-voltage distribution cabinet comprises a cabinet body and a heat dissipation plate, wherein a top cover is arranged at the top of the cabinet body; the bottom of the cabinet body is fixed on a base; a cabinet door is arranged on the front surface of the cabinet body; a mountingplate is fixed in the cabinet body; an air outlet is formed in the back surface of the cabinet body; the heat dissipation plate is attached to the back surface of the mounting plate; a heat circulating pipe is arranged on the heat dissipation plate; a pump shell is fixed on the heat circulating pipe; the inside of the pump shell is connected with a rotating shaft of a motor in a rotatable manner;a first fan blade is fixed on the rotating shaft in the pump shell; the motor is fixed on the air outlet through a fixing rod. According to the low-voltage distribution cabinet with the heat dissipation and dust prevention functions, through combination of the heat dissipation plate and the heat circulating pipe, heat conduction liquid in the heat circulating pipe is circulated through the first fan blade to accelerate discharging of heat; convection is formed on the surfaces of heat dissipation fins through a second fan blade, so that the heat dissipation effect is enhanced; electrical elements are isolated from external air flow, so that entry of dust is prevented, and the dust prevention effect is thorough.

Description

technical field [0001] The invention belongs to the technical field of power distribution cabinets, and in particular relates to a low-voltage power distribution cabinet with heat dissipation and dustproof functions. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. The ra...

Problems solved by technology

However, there are still shortcomings: because the external air passes through the inside of the power distribution cabinet, although it passes through the dust-proof device, there is still dust in the airflow. After long-term use, the surface of electrical components will still accumulate dust, and the dust-proof is not complete.
