INTEGRATED RADIATOR ASSEMBLY

Provided is an integrated radiator assembly, and belongs to the field of vehicles. The integrated radiator assembly includes: multiple groups of refrigerant flat tubes, wherein multiple refrigerant flow channels are disposed in each group of the refrigerant flat tubes; a refrigerant collection tube, disposed at two ends of the multiple groups of refrigerant flat tubes and in communication with each of the refrigerant flow channels; multiple groups of cooling liquid flat tubes, wherein each of the refrigerant flat tubes is externally sleeved with each of the cooling liquid flat tubes, and multiple cooling liquid flow channels are formed between an outer surface of the cooling liquid flat tube and an outer surface of the refrigerant flat tube; and a cooling liquid collection tube, disposed at two ends of the multiple groups of cooling liquid flat tubes and in communication with each of the cooling liquid flow channels, wherein the cooling liquid collection tube is separated from the refrigerant collection tube, so that a refrigerant circulates in the refrigerant flat tubes and the refrigerant collection tube, and cooling liquid flows in the cooling liquid flat tubes and the cooling liquid collection tube. The integrated radiator assembly is capable of meeting heating use requirements of a heat pump system without air supplement and enthalpy increase.
