Abstract: A clothes airer comprises hinged side bars supporting a number of hanging rails `B', and cutouts `F' for clipping or resting on a front bar `C' of a range cooker 'D'. Preferably, a hinge point `A' enables the airer to fold flat for storage. In use, the airer attaches to the front bar of any range cooker and utilises the `waste' radiated and convected heat from the front surface of the cooker to air and dry clothing or bedding `E' which is draped over and vertically suspended from the hanging rails.

Abstract: The heat exchanger 1 has a pair of spaced circular inner and outer walls 4,5 joined by a series of spaced ribs 6 extending in an axial direction between the opposite ends 2, 3 to form a series of parallel passageways 7. Interconnecting ports (e.g. 14a, fig 3) are milled or formed between adjacent passageways (fig 3), or groups of adjacent passageways (fig 4), at opposite ends of the extrusion, such that in one embodiment the fluid flows in opposite directions in the adjacent passageways or groups of adjacent passageways. A pair of end caps 9,10 close the ends 2,3 and have a respective fluid inlet 11 and a fluid outlet 12. An alternative embodiment (fig 5) has helical passageways. The heat exchanger may be an extrusion, moulding or welded; may be transparent or partially/wholly coloured black to absorb heat; and can be cylindrical, curved or flat. The ribs may be inclined to form a triangular cross-section passage (fig 7). The heat exchanger may be a radiator, solar panel, fireproof wall or part of a food processing machine; or cool a horticultural or industrial light bulb, or a chimney.
