<p>The heat exchanger has fixed surfaces transmitting sensible heat, and is mounted between an air inlet and outlet passage so as to recover heat from the stale air, e.g. in a private house. The exchanger (1) comprises a large number of adjacent flat heat-conductive elements extending in the direction of the air currents and forming partitions which are airtight and heat- conductive and connected together. Thus two separate air passages (3,4) for fresh and stale air, are formed by them. The exchanger can be in one piece and of copper sheet in a meander pattern.</p> |
