Charger cabinet and rainproof plate

Abstract

The invention relates to the field of electric vehicle charging equipment cooling, in particular to a charger cabinet and a rainproof plate. The charger cabinet comprises a cabinet body and a heat dissipation window, the heat dissipation window comprises an outer shell and the rainproof plate arranged on the inner side of the outer shell, a heat dissipation opening is formed in the rainproof plate, an outer baffle obliquely extending downwards is arranged on the outer side of the heat dissipation opening, and an inner baffle is arranged on the inner side of the heat dissipation opening. The inner baffle is provided with an inclined section extending upwards in an inclined mode and a bent section bent towards the rainproof plate. An airflow channel is formed between the inner baffle and theouter baffle, and the surface of the inner baffle forms a reflecting surface of airflow passing through the airflow channel below the inner baffle. After entering the cabinet, the airflow of the heatdissipation window is reflected towards the inner side of the cabinet by the surface of the inner baffle above the corresponding airflow channel, so that electrical equipment at the same height of the heat dissipation window can be effectively cooled, and the problem of poor heat dissipation effect on the electrical equipment at the lower part of the cabinet caused by the fact that the airflow passes above the cabinet is solved.

Description

technical field [0001] The invention relates to the field of cooling of electric vehicle charging equipment, in particular to a charging machine cabinet and a rainproof plate. Background technique [0002] At present, the automobile industry is developing in the direction of environmental protection and cleanliness, and electric vehicles are an important product of this development trend. As the energy supply equipment of electric vehicles, the reliable and reasonable structural design of the charger has very important practical significance. The actual working environment of the charger is harsh. Long-term exposure to the sun, rain, catkins, sandstorms, etc. will affect the normal operation of the charger, causing the charger to work in an abnormal state. In order to satisfy heat dissipation, the existing DC chargers often sacrifice the protection level as a price. Most of them only set baffles outside the heat dissipation vents to cover the upper part of the heat dissipat...
