The invention provides a condensing device and clothes processing equipment, the condensing device comprises a condensing air duct and a turbulent flow module, and the turbulent flow module is arranged in the condensing air duct and comprises turbulent flow blades and a blade shaft; the turbulent flow blades are in a spiral shape and are arranged on the blade shaft in the mode that the spiral angle can be adjusted. When airflow flows along the condensation air duct from bottom to top, a controllable turbulent flow effect is generated through the turbulent flow blades with the adjustable spiral angles, so that the airflow forms vortex or turbulent flow, and the contact area and the contact time between the airflow and condensate water are remarkably increased; not only is the sufficiency and uniformity of heat exchange enhanced, but also different drying conditions can be adapted by adjusting the spiral angles of the turbulent flow blades, the flow velocity distribution of airflow is optimized, and the condensation efficiency is effectively improved; on the basis of ensuring the condensation efficiency, the system is allowed to maintain equivalent heat exchange performance at a lower drying fan rotating speed, so that the fan energy consumption and the operation noise are reduced.
