Electrical control cabinet with heat dissipation protective device at top part

Abstract

The invention discloses an electrical control cabinet provided with a heat dissipation protective device at the top part. The electrical control cabinet comprises a control cabinet body, wherein an opening is formed in the front surface of the control cabinet body, one side of the opening is provided with a cabinet door, the cabinet door is connected with the control cabinet body through a hinge, one side of the cabinet door is provided with a lock catch, fan blades are driven to rotate by power, the heat of the electrical control cabinet is dissipated through the rotation of the fan blade, so that the electrical control cabinet has better heat dissipation effect, the lower end of a ventilation pipe is provided with a heat dissipation frame, the heat of the electrical control cabinet is dissipated more quickly by means of the heat dissipation frame, and the control cabinet body is protected by a protective plate and a protective frame, so that the control cabinet body is more solid. The electrical control cabinet provided with the heat dissipation protective device at the top part is simple in structure, can dissipate the heat inside the electrical control cabinet quickly, and can prevent tiny debris particles and a lot of dust from falling into the cabinet from the top part, thereby protecting the electrical appliance elements inside the electrical control cabinet and prolonging the service life of the electrical appliance elements.

Description

technical field [0001] The invention relates to the technical field of electrical control cabinets, in particular to an electrical control cabinet with a heat dissipation protection device on the top.
