Beschreibung
Zusammenfassung:	A ventilation unit for heat radiation of an electrical cabinet mainly comprises bottom fans for sending air into the cabinet body and a top fan for sending air to the outside. Two bottom fans are symmetrically arranged at both bottom sides in the cabinet body, and the top fan is arranged on the top of the cabinet body and connected with a heat-generating body in the cabinet through an air channel to send air to the outside through a grid. The bottom fans and the top fan are arranged in the cabinet for sending air into the cabinet and to the outside respectively, and air is forced by the air channel to flow by the heat-generating body so as to take away heat and carry out forced heat convection for the heat-generating body, thereby substantially improving heat radiation efficiency. Moreover, the ventilation unit is simple in structure and convenient for maintenance.
