Abstract
A heat exchange device includes a heat exchanger and a water guider. The water guider is arranged on the heat exchanger and has a water guide groove, and condensed water on at least a part of the heat exchanger can flow out through the water guide groove. The heat exchange device has a good drainage performance, can prevent the condensed water from accumulating, and thus improves a heat exchange area and a heat exchange efficiency of the heat exchanger.
