A heat exchanger and manufacturing method thereof, include a plurality of radiating pins which are aligned at a predetermined interval and a plurality of refrigerant tubes which are positioned to be penetrated among the radiating pins and through which refrigerant passes. In addition, the refrigerant tubes are mutually connected by the connection pipes, inflow/discharge pipes are respectively connected with the refrigerant tubes of one side, and connection portions of the refrigerant tubes and connection pipes and connection portions of the inflow/discharge pipes and the refrigerant tubes are simultaneously joined by a melting processing. Accordingly, the heat exchanger can reduce a manufacturing process and cost, by simultaneously joining a connection portion of the refrigerant tubes and connection pipes and connection portion of the inflow pipe and discharge pipe, by a melting processing. |
