[0002] Electrical cabinets are made of steel and are used to protect the normal operation of electrical components. The materials used to make electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the production of electrical cabinets. Electrical cabinets are widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. Electrical components are distributed inside the electrical cabinet, and electrical components will generate a lot of heat when working. The existing electrical cabinets use natural wind heat dissipation when dissipating heat. This heat dissipation method easily causes heat to stay in the electrical cabinet for a long time, which will affect the normal operation of the electrical components in the electrical cabinet and also reduce the service life of the electrical components.
