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.

In an arrangement having a passage through which heated fluid flows, a device for cooling said heated fluid comprising: first heat exchange means including a first heat exchanger exposed to said heated fluid for vaporizing liquid coolant; second heat exchange means including a second heat exchanger

In an arrangement having a passage through which heated fluid flows, a device for cooling said heated fluid comprising: first heat exchange means including a first heat exchanger exposed to said heated fluid for vaporizing liquid coolant; second heat exchange means including a second heat exchanger for condensing coolant vapor formed in said first heat exchanger; means responsive to a parameter which varies with the temperature of the fluid in said passage downstream of said first heat exchanger, said parameter responsive means increasing the heat exchange between said first heat exchanger and a cooling medium in contact with said first heat exchanger; a first pump for pumping liquid coolant from said second heat exchanger to said first heat exchanger; a reservoir; a first valve which controls fluid communication between said reservoir and one of said first and second heat exchangers, said first valve including means for opening and establishing fluid communication between said reservoir and said one of said first and second heat exchangers when said cooling device is not in use.
