Liquid cyclone, heat exchanger including liquid cyclone and air conditioner including liquid cyclone

The utility model provides a liquid cyclone, a heat exchanger including the liquid cyclone and an air conditioner including the liquid cyclone. The liquid cyclone comprises a basal body formed by a panel veneer, wherein a first end of the basal body is a closed end with an inner chamber, and a second end of the basal body is an open end with a plurality of flowing holes communicated with the inner chamber; the flowing holes are formed by continually circling the panel veneer; and the panel veneer parts among the flowing holes parallelly extend and are combined to form connecting parts. According to the liquid cyclone provided by the utility model, the panel veneer of the basal body formed by the panel veneer is pressed to form the connecting parts and the flowing holes under the action of an external force, and the flowing holes are communicated through the inner chamber of the closed end so as to obtain the liquid cyclone; owing to the flow dividing parts formed by the flowing holes, a special welding tool r
