Abstract
An inverter power cabinet includes a cabinet body and power devices arranged in the cabinet body. The cabinet body includes a low-protection grade installation cavity and an airtight high-protection grade installation cavity hermetically isolated from each other; the power devices include high protection grade power devices arranged in the low-protection grade installation cavity and low-protection grade power devices arranged in the high-protection grade installation cavity; the low-protection grade installation cavity has an outer cold air inlet and an inner hot air outlet in communication with outside world, and a first fan is provided in the low-protection grade installation cavity; and the inverter power cabinet includes a heat exchanger configured to dissipate heat of the high-protection grade installation cavity. The inverter power cabinet can avoid direct contact of the low-protection grade power devices with a harsh environment, thereby preventing the contaminated cold air from damaging the low-protection grade power devices.
