Heat exchanger and related method of manufacture

Abstract

A heat exchanger for an internal combustion engine of a motor include first and second radiator tanks and a plurality of radiator tubes extending between the first and second radiator tanks. The first radiator tank includes a plurality of walls. Brazed joints are between the plurality of walls to make the first radiator tank liquid tight. Brazed joints are also between the plurality of radiator tubes and the first and second radiator tanks. An oil-cooling structure is disposed inside the first radiator tank. The brazed joints between the plurality of walls and between the plurality of radiator tubes and the first and second radiator tanks are simultaneously formed.
