Abstract：

Develops the device considering the lack of dehumidification capacity, serious condensation in air-conditioned rooms during wet seasons, and poor air quality caused by the capillary terminal. The device improves air velocity by adopting a special parabolic airflow channel design and its heat transfer area can be increased or decreased according to the load demand by modular design. The air inside the cabinet circulates automatically by density difference without extra driving power, and the device has dehumidifying capacity resulting from a greater heat transfer area. Presents the calculation of heat transfer area per unit capillary and air volume flow rate. Experiment results show that the device has favorable heat transfer effects and dehumidifying capacity.
