Intercooler for supercharged internal combustion engine

摘要

An intercooler includes a first heat exchanger into which liquid coolant is sprayed and subsequently converted to vapor via the absorption of its latent heat of vaporization. The vapor is condensed in a radiator under the influence of a fan. The condensate is pumped back to the first heat heat exchanger via an thermostatically controlled expansion valve. When the intercooler is not in use it is filled with liquid coolant to prevent the intrusion of contaminating air. Excess coolant may be forced into the system when cold to purge out any non-condensible matter.
