HEAT EXCHANGER AND METHOD FOR COOLING A HEAT ENGINE IN TWO-PHASE MODE.

摘要

P The circulation of the cooling fluid in the heat exchanger is done in two passages, first by a lower sub-assembly (3b) of a bundle of horizontal tubes (3) between lower chambers (1b and 2b) of two fluid boxes (1 and 2), then through the upper sub-assembly (3h) of the tube bundle between the upper chambers (2h and 1h) of the fluid boxes (2 and 1). Only the fluid in the liquid state can pass from the lower chamber (2b) to the upper chamber (2h) of the second fluid box via a bypass line (6). /P
