Description

Heat dissipation waterproof structure for discharge cabinet Technical Field The utility model relates to the technical field of discharge cabinets, in particular to a heat dissipation waterproof structure for a discharge cabinet. Background "Discharge cabinet" generally refers to a special device for safely releasing electrical energy stored in a device or system, commonly found in electrical, industrial or laboratory settings, and in addition, the discharge machine operates in an open air environment and is subject to severe weather such as strong winds, storms, insolation, and the like. In the prior art, a group of fan structures are arranged on the back or two sides of the cabinet body of the discharging cabinet, so that the heat dissipation of the cabinet body is realized, but a great amount of dust is introduced into the cabinet body from the fan frame due to the design of the heat dissipation fan, and the electronic components are possibly damaged due to the phenomenon that the electrostatic discharge occurs when the dust is covered on the electronic components. And some other factories can dispel the heat through seting up the air flue on the cabinet body, but the cabinet body itself only has one deck iron sheet, if do not cooperate the structure after seting up the air flue, easily lead to the rainwater to leak to the cabinet internal, lead to cabinet internal body electronic component to damage.
