Portable and other compressors frequently use automobile type radiators. One form of construction uses corrugated metal sheets, laid together and dip-brazed; another type uses an aluminium cooling matrix. The designs are based on the principle of providing a large exposed area in a high conductive material.

Air is forced through by a motor driven fan. Analysis of this type of cooler is best done by the use of characteristics obtained from tests. Suppliers of coolers have comprehensive design charts for selecting the appropriate type, and much practical experience in choosing the ideal design parameters.
