The invention relates to a condensation and heat-exchange device, drying equipment and clothes drying equipment. The condensation and heat-exchange device comprises a thermal power unit and a heat-conducting pipe. The thermal power unit is provided with a thermoelectric material, and a first heat-conducting layer and a second heat-conducting layer which are respectively positioned on two sides of the thermoelectric material; the thermal power unit is configured to respond to electric current flow in the thermoelectric material to exchange heat between the first and second heat-conducting layers. The heat-conducting pipe is provided with a first end and a second end, wherein the first end is connected with the second heat-conducting layer, and the heat-conducing pipe is configured to transfer heat between the second heat-conducting layer and the second end. Compared with the prior art, the condensation and heat-exchange device is small in size, capable of saving space, long in service life and lower in maintenance cost. In addition, in case that the same effect is required to achieve, the condensation and heat-exchange device is more water-saving and energy-saving, and more economic and environmental friendly.
