Heat transfer device of doing benefit to frost

The utility model provides a heat transfer device of doing benefit to frost, including finned heat exchanger, the finned heat exchanger bottom is equipped with the intake pipe that is used for lettingin the refrigerant along its base length direction, the inlet end of intake pipe all is located beyond finned heat exchanger's the side edge rather than the end of giving vent to anger. Because the finned heat exchanger bottom is equipped with the intake pipe along its base length direction, the high temperature, the high pressure refrigerant that export from gas compressor take the lead in through the finned heat exchanger bottom for under the prerequisite that does not reduce the heating capacity, the finned heat exchanger bottom keeps higher temperature, forms and heats the cold -zone. After the adnexed frost of finned heat exchanger melts the rivers that form and falls to heating the cold -zone, because it was higher to heat cold -zone ( finned heat exchanger bottom) temperature, above -mentionedly melt the w
