Deicing device utilizing gas exhaust waste heat of diesel engine

The invention provides a deicing device utilizing gas exhaust waste heat of a diesel engine. The deicing device comprises a hot-end heat exchange tube (1), a mixing tube (2), a cold-end heat dissipation tube row (3) and an air blower (4), wherein the mixing tube (2) comprises an inlet section, a jet-flow section and an outlet section; one end of the hot-end heat exchange tube (1) is inserted intothe jet-flow section of the mixing tube (2); one end of the cold-end heat dissipation tube row (3) is connected to the outlet section of the mixing tube (2); and the inlet section of the mixing tube (2) is connected to the air blower (4). The deicing device is simple in system configuration, and is simple and convenient to operate. Gas exhaust heat of the diesel engine is effectively recycled through the heat exchange tube and the jet-flow tube row component, so that heating and deicing of a diesel engine radiator, and energy-saving and emission-reducing technical effects are realized.
