Abstract (en)
The exhaust gas heat exchanger (1) for a road vehicle internal combustion engine has a square- or rectangular-section housing (2). It is made of a U-section (2') with a shallow inverted U- section lid (2''). The interior contains an array of flattened rectangular-section tubes (3) with fins (4) made of corrugated metal sheet between them. Cooling fluid may flow past the fins to cool hot exhaust gas before entering silencers and catalysers. The exhaust gas may flow straight through and the cooling fluid may flow through side connections (5).
