Abstract
The present invention relates to an air-cooled high-power inverter power cabinet with a high radiation structure, which comprises a cabinet (1) and power units (6) arranged in an inner cavity of the cabinet (1) and is characterized in that two sides of the cabinet (1) towards each other are arranged with an air inlet door (2). An exhaust fan (5) is positioned on top of the cabinet (1). The power unit (6) in the inner cavity of the cabinet (1) is provided with a spot or strip layout to form clearances amongst power units (6). These clearances and radiating air passages of power units form air passages (4) in the inner cavity of the cabinet (1). An inlet scoop of the exhaust fan (5) is arranged just towards the air passage (4). The present invention adopts a structure of front and rear air entry into the cabinet and forced air exit on a middle top of the cabinet, thus adapting to a radiator with a wide power unit cross section and a shorter air passage, increasing radiating efficiency remarkably compared with similar products, ensuring high cabinet radiating efficiency and correspondingly decreasing size of the cabinet with a same holding capacity.
