The invention discloses a heat dissipation structure of a power distribution cabinet, comprising a power distribution cabinet body, wherein the power distribution cabinet body comprises a casing; an opening is formed on one side of the casing; bolt holes are formed above and below one side of the casing where the opening is located; a support plate is fixedly connected to the bolt hole through a bolt; a passage is fixed inside the support plate; sliding passages are uniformly fixedly connected on two sides of the support plate; heat dissipation fins are arranged on the outer side of the sliding passages; chutes are fixedly connected to the two sides of the heat dissipation fins; the chutes and the sliding passages are connected in a sliding manner; through holes are formed on one side of the support plate; the through holes are uniformly distributed in the gaps between the heat dissipation fins; a cover plate is fixedly connected to one side of the support plate far away from the casing; a fan is installed on the inner side of the cover plate; and an air outlet is formed on one side of the fan. The heat dissipation structure in the invention has reasonable design, simple structure,good heat dissipation effect and convenience for installing and fixing, and is worth promoting.
Description
technical field [0001] The invention belongs to the technical field of power distribution cabinets, and in particular relates to a heat dissipation structure of a power distribution cabinet and a manufacturing method thereof. Background technique [0002] When the closed switchgear is running, because there are many heating components in the cabinet, the excessive temperature rise will cause the mechanical and electrical performance of the electrical equipment to decline, and finally lead to the failure of the high-voltage electrical equipment, and even cause serious accidents. In order to ensure the safe operation of high-voltage electrical appliances within the working life, the temperature rise in the cabinet must be controlled within the allowable temperature specified in the standard. The existing heat dissipation fins are prone to static electricity when used for a long time, and a large amount of dust will be stained on the fins, which affects the heat dissipation eff...
