Remeber from a while back I think it was steve scotts rally car in one of the mags and it was littered with these little modules in the engine bay called heat exchangers. Anyone care to enlighten me on what they do please?
thanks
Steve

 

isnt that just another name for a charge cooler?

prob. completely wrong

 

heat exchanger is just a unit that allows heat to be exchanged between 2 mediums without them touching, eg radiator - water to air, intercooler air to air, chargecooler - air to water
