Abstract

A compact cooling system including a radial fan directing air flow outwardly and a plurality of heat exchangers disposed around the radial fan. Each heat exchanger has a plurality of tubes extending between an inlet header and an outlet header, with the headers extending generally in the same direction as the fan axis. A system inlet is connected to the inlet headers and a system outlet is connected to the outlet headers, whereby the length of the connection between each heat exchanger and the system outlet and system inlet is generally the same for each heat exchanger.
