For addressing the above problem, the utility model provides the heat pump drier with heat pipe thermal recovery unit that a kind of programming rate is fast, dehumidification rate is high.

The utility model solves the technical scheme that its technical problem adopts: a kind of heat pump drier with heat pipe thermal recovery unit, comprise indoor dehumidification heating system, the indoor air channel of outdoor air energy heating system and internal fan, indoor air channel is divided into air return section and air supply section along airflow direction, indoor dehumidification heating system comprises regenerator and by the first compressor, the first condenser, the refrigerant loop that the first expansion valve and the first evaporimeter are in turn connected to form, the cold junction of regenerator, the first evaporimeter, the hot junction of regenerator and the first condenser set gradually along airflow direction in air return section, outdoor air energy heating system comprises by the second compressor, be located at the second condenser in air supply section, the second expansion valve and be located at the refrigerant loop that second evaporimeter in outside, indoor air channel is in turn connected to form.

Be further used as the improvement of technical solutions of the utility model, regenerator is heat pipe regenerator, and the cold junction of regenerator is connected by the tracheae on top and the liquid pipe of bottom respectively with the hot junction of regenerator and forms the inner loop that is filled with refrigerant.

Be further used as the improvement of technical solutions of the utility model, the cold junction of regenerator and the hot junction of regenerator are surface-type heat exchanger.

Be further used as the improvement of technical solutions of the utility model, blower fan comprises the first blower fan of being located at air return section entrance and the second blower fan of being located at air supply section exit.

Be further used as the improvement of technical solutions of the utility model, also comprise outdoor air channel, the second evaporimeter is located in outdoor air channel, and in front side and/or rear side be provided with the 3rd blower fan.

The beneficial effects of the utility model: in this heat pump drier with heat pipe thermal recovery unit, drying medium flows through successively cold junction, first evaporimeter of regenerator in indoor air channel, hot junction, the first condenser and second condenser of regenerator under the effect of blower fan.Wherein, drying medium temperature when the cold junction of regenerator of flowing through, the first evaporimeter declines, and discharges moisture; After the hot junction of flowing through regenerator, the first condenser and the second condenser, by three times, heated after-blow to material to be dried.The utility model, by above-mentioned design, is removed the moisture in drying medium before intensification, and then improves backheat speed by three grades of heating, thereby when raising drying medium carries wet ability, improves effect on moisture extraction.
