PURPOSE: An installation structure of refrigerant tube of aluminum heat exchanger is provided to help increase of productivity and heat exchanging efficiency of the heat exchanger. CONSTITUTION: A heat exchanger includes a pair of header pipes(10); a plurality of refrigerant tubes(12) joined to the header pipes in a way that one ends of the refrigerant tubes are inserted to side surfaces of the header pipes; and cooling fins interposed among the refrigerant tubes. An alignment device, a pair of fixing blocks(20), is placed to the header pipes to align front ends of the refrigerant tubes on a same plane by restricting movement of the refrigerant tubes inserted to the header pipes at fixed position.
