ABSTRACT:
Engineers have learned that if the temperature of coolant within a heat exchanger is raised above the coolant's boiling point by the entering hot fluid, the boiling of the coolant can cause corrosion within the heat exchanger. The heat exchanger of the present invention includes a heat exchanger body that defines a plurality of fluid passages that are operable to exchange heat with a plurality of liquid passages. At least one of the liquid passages is re-sized to include a greater cross-sectional flow area than another liquid passage. Thus, a greater amount of liquid can flow through the coolant passage with the greater cross-sectional flow area, thereby reducing the risk of boiling coolant that may cause corrosion within the coolant passage.
