Abstract: According to the present invention, a heat exchanger comprises a coolant tube, and a fin having a collar coupled with the coolant tube and projected from a plate part, wherein the collar includes a call connection non-contacting part having an inner diameter larger than an outer diameter of the coolant tube, the call connection non-contacting part not contacting an outer surface of the coolant tube, and a call connection contacting part, an inner surface of the call connection contacting part contacting the outer surface of the coolant tube when the coolant tube is inserted, wherein a connecting member is positioned between an inner surface of the call connection non-contacting part and the outer surface of the coolant tube. Accordingly, without a tube expanding process for tube expanding the coolant tube, the coolant tube may be brought in tight contact with the fin. Further, the furnace brazing process is performed to minimize the defect rate.
