Abstract
A heat exchanger disclosed in the present disclosure includes a first collecting pipe, a second collecting pipe, a number of heat exchange tubes, at least one fin and a hygroscopic colloid. The heat exchange tube has a pipe wall and a refrigerant flow channel for a refrigerant to circulate. The heat exchange tube has a first end and a second end. The refrigerant flow channel extends from the first end to the second end along an extension direction of the heat exchange tube and extends through the heat exchange tube. The hygroscopic colloid is adhered to at least part of an outer surface of the heat exchange tube and/or the fin. The present disclosure also discloses a heat exchange system having the heat exchanger and a method for making the heat exchanger. The hygroscopic colloidal material of the present disclosure is friendly to metal surfaces.
