A radiator comprising a plurality of longitudinally finned tubes formed from extruded aluminum and extending between upper and lower header pipes likewise of extruded aluminum. A water-tight joint is formed at the junction of each finned tube with the adjacent header by means of an interference fit nipple. The fins are shaped so as to define a gap between adjacent finned tubes through which air to be heated may be drawn. Such air enters a chamber defined between each adjacent pair of finned tubes and exits to the rear via louvers formed in the rear fins of the finned tubes, taking the general direction of arrows A. A degree of control of the heat output of the radiator may be achieved by rotation of a flap located at the bottom of the space between the radiator and the adjacent wall surface. |
