The present invention discloses an inverter, a sealing air duct and a heat dissipation system. The inverter includes: an enclosure, having a first cavity and a second cavity that are isolated from each other and sealed; a magnetic conversion circuit including magnetic elements that is arranged in the first cavity; a power conversion circuit including power tubes that is arranged in the second cavity; a heatsink, arranged at the bottom of the enclosure and located outside the first cavity and the second cavity; a sealing air duct, arranged outside the second cavity, where the sealing air duct includes at least one columnar pipeline formed by a heat dissipation surface and a bottom surface, the at least one columnar pipeline is sealed at two ends, the bottom surface is formed by a side wall of the second cavity or a substrate of the heatsink, and the bottom surface includes an air inlet and an air outlet to communicate with the second cavity and the at least one columnar pipeline. The apparatus according to the embodiments of the present invention lowers air temperature inside a cavity, improves heat dissipation efficiency, and thereby enhancing reliability and life cycle of devices and reducing product size and noise. |
