摘要
The radiator comprises a number of concentric tubular arrangements (11a,11b). Each arrangement consists of two concentric tubes (13,14) welded together at the ends to form a watertight annular space (18) between 25mm and 10mm wide. The annular waterways of the two tubular arrangements are connected at the top (19) and at the bottom (20). The bore (17) of the inner table (14) is open to allow free passage for convected air currents. Water is introduced into the radiator near to the base of one tube at an inlet connection (21) and flows in the direction of the arrows upwards through the annular space, through the interconnection (19) and downward in the second tube, returning to the outlet (22) through the interconnection (20).
