The invention discloses a solar photovoltaic
heat pump dryer, which comprises a box body and an air-
drying box. Four photovoltaic modules are arranged on the top of the box body, and a control box is arranged on the left side of the box body. There is a sliding door on the front, and a
radiant heat pipe is arranged inside the door, a
heat pump unit is arranged on the right side of the
radiant heat pipe, and six battery boxes are arranged on the upper part of the
heat pump unit; Air outlet, and an air outlet is provided on the right side of the air-
drying box, and a temperature sensor is installed on the upper surface of the air outlet, and a heat dissipation
pipe is provided inside the air-
drying box. Since the photovoltaic module can provide power, the set The auxiliary
heat pipe can provide auxiliary heat for the heat pump unit. At this time, the heat pump unit raises the heat and transports it to the heat dissipation pipe. At this time, the temperature sensor detects the temperature and starts the supplementary
heat pipe, so that the high-temperature gas flows out from the air outlet, and the objects at the air outlet are dried. The object is dried, so the device is worth popularizing.
