Description

Technical Field

[0001] The invention relates to the field of electrical cabinets, and in particular to an electrical cabinet with good heat dissipation effect. Background Art

[0002] Electrical cabinets are made of steel to protect the normal operation of components. Electrical cabinets are generally made of 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.

[0003] However, current electrical cabinets are generally rectangular cabinets of fixed shape and cannot be deformed. The heat dissipation of the electrical cabinets is limited. Moreover, when used outdoors, the heat dissipation requirements for the electrical cabinets are relatively high. When the electrical cabinets are cooled, they are generally cooled by internal cooling fans, which makes it inconvenient to make reasonable use of natural wind power and affects the heat dissipation effect of the electrical cabinets. Therefore, the inventor invented an electrical cabinet with good heat dissipation effect to solve the heat dissipation problem of the electrical cabinets. Summary of the invention
