<p>A hollow cast iron radiator element (1) to be heated internally by water has a longitudinal front fin (2) and on the opposed sides a series of short inclined fins (4) which define channels for deflecting and directing heated air streams upwards and away from the rear of the element to a further channel between the front fin and the ends of the fins (4). Various inclinations of the short fins are proposed including extending them parallel to the front fin, which is vertical in use. Furthermore, different shapes of the interior of the element for heat transfer surfaces to conduct heat to the front fin (2) and the series of fins (4) are described. <IMAGE></p> |
