Abstract

A heat exchanger, for heating or cooling fluids, incorporates a number of parallel elements which are good conductors of heat, and which are held in a transverse support, so that thre is a narrow gap between neighbouring elements. Each element has a convex part on one side and is fitted with a soruce of heat which may ben an electrical resistance or a tube carrying a hot fluid, or a source of cold, e.g., a tube carrying a cold fluid. A primary fluid under pressure, on one side of the exchanger flows over the elements and through the gaps, and mixes with a secondary fluid on the other side, entraining it and forming a combined stream. In alternative forms, the elements themselves may constitute the source of heat or cold, or the exchanger may be a perforated sheet, the holes forming the parallel elements and the gaps, the heat sources being fixed on to pieces cut and bent inwards. The flow of primary fluid under pressure, on one side of the exchanger allows a large flow of secondary fluid on the other side, so that only a small fan or pump is needed, compared with one which would be required for the whole flow. For a given duty, therefore, the space occupied is much less than with existing exchangers. In addn. the transfer of heat to the primary fluid is uniform.
