[0002] The defrosting device of the low-temperature heat pump heating unit is an apparatus installed on the outdoor low-temperature heat pump heating unit, so as to heat and melt the ice when the external environment temperature is low. The traditional defrosting device includes a water receiving base, a base, a drainage groove, a fin pad, a heating pipe and a drainage hole. The water receiving base is tilted and fixedly installed on the base, a drainage groove is sunken at the edge of the water receiving base, a drainage hole is opened at the bottom of the drainage groove, a heating pipe is arranged along the drainage groove inside the drainage groove, and a fin pad is arranged above the drainage groove. It has the characteristics of ensuring the safe operation of the heat pump unit, but the freezing range is large and the heating range is small. The defrosting process is slow and affects the work efficiency. The water discharged after melting is easy to remain, so it will freeze again when not heated, affecting the use.
