Claim:
1. An intercooler for an internal combustion engine comprising: a plurality of heat transfer plates arranged parallel to one another to define gaps therebetween, the plates having respective first parallel edges coinciding with an air inlet end and second parallel edges shorter than the first parallel edges coinciding with an air outlet end, each plate having internal passages carrying a liquid coolant and extending transverse to an airflow direction between the plates; and a plurality of fin units disposed in the gaps and contacting adjacent pairs of the plates, at least one of the fin units comprising a plurality of fins extending along the airflow direction, adjacent fins converging with one another along the airflow direction such that a first spacing between adjacent fins at the air inlet end is greater than a second spacing between adjacent fins at the air outlet end, and such that adjacent fins define therebetween a plurality of airflow passages, respective airflow passages having an inlet area greater than an outlet area, the inlet and outlet areas measured perpendicular to the airflow direction.
