The heat exchanger has a fan which impels air through it and a conduit system (21,22) in the air passage is for circulating fluid under heat exchange with the passing air. The passage of air is limited between two plates (14,17) arranged one above the other at a reciprocal distance from each other and with a peripheral gap (30) between them. - This gap acts as an air inlet or outlet, whilst a central opening (15) also acts as an air outlet or inlet in the upper plate. The conduit system is arranged as a tube or hose coil concentrically placed between the plates around the central aperture in front of the peripheral gap. |
