HEAT EXCHANGER FOR INTERNAL COMBUSTION ENGINE RECYCLED EXHAUST GASES

摘要

The exhaust gases circulate inside an array of tubes (2) cooled by a refrigerating liquid. The efficient length of the tube array (2) is determined on the basis of the efficient cross-section S of gas passage in the tube array (2) such that the EF/S ratio between the efficient length of the tube array (2) and the efficient cross-section S of the gas passage in the tube array (2) ranges between a maximum value EF/S max and a minimum value EF/S min for which the clogging of the tube array is minimal. The invention is applicable to internal combustion engines, in particular of motor vehicles.
