PURPOSE:To reduce processing cost, improve heat transfer characteristics and prevent electric corrosion by a method wherein legs for connecting heat medium tubes with flat plate heat absorbing fins and other curtain wall as well as fixing legs connecting the tubes with reinforcing members are formed integrally. CONSTITUTION:A flat plate 1, the heat absorbing and dissipating fins 2, legs 3 for heat medium tubes, the heat medium tubes 4, the connecting and fixing legs 6 and the connecting legs 8 are formed integrally by a metal such as aluminum, for example. According to this method, man-hours for attaching the heat medium tubes 4 to the legs 3 for heat medium tubes are omitted, a countermeasure for preventing electric corrosion of the heat medium tubes 4 and the legs 3 for the heat medium tubes becomes unnecessary and, further, contacting thermal resistance may be eliminated. The curtain wall of desired size may be formed by the combination of the connecting and fixing legs 6 and the connecting and reinforcing members 7 as well as the combination of the connecting legs 8 and other curtain walls 9.
