Abstract

The utility model discloses a heat abstractor for single -tube IGBT, the lower surface fixedly connected with heat conduction silicone grease has the heat dissipation copper plate of heat conduction silicone grease's lower surface, and single -tube IGBT heats when normal work, and through the heat conduction of bottom heat conduction silicone grease to heat dissipation copper plate, and then from heat dissipation copper plate transfer insulating board, and small -size motor starts and drives fan rotation, and starts to the base bottom, heat conduction silicone grease, heat dissipation copper plate and insulating board carry out air cooling, and fan air inlet also is provided with metal dust screen. Single -tube IGBT is accessed in the circuit, and fixedly connected with an electrified wire at the metal bolt, and the current sensor is fixedly connected to the electrified wire end, and the current sensor is responsible for detecting the current size in the circuit, and guarantees single -tube IGBT can normally operate, and the right side of current sensor also is provided with insulating board, and avoids the interference single -tube normal operation.
