The core usually sits between a cooler/radiator’s inlet and outlet tanks, and it contains the series of tubes and fins that transfer heat away from the engine. Cooler cores come in a variety of shapes and sizes. There are even some radiators with two or three cores. In general, larger pieces of equipment need larger radiators to keep their engines cool.
Most cooler cores are made of metal, with aluminum being the most common type. Older models may have copper or brass cores. The purpose of the core is to transfer heat away from the engine, so whatever materials are used must be effective heat conductors.
There are different types of core design, but the most common is a fin-and-tube construction. In this type of cooler core, a length of metal tube or pipe bends around many times within a compact pattern. As the liquid coolant snakes its way through the tubing and cool air passes over it, heat radiates away from the engine. A series of thin metal fins around the tubing improves this process by providing extra surface area through which the heat can transfer.
