Abstract
A method of forming a cast heat exchanger plate includes forming at least one hot core plate defining internal features of a one piece heat exchanger plate and at least one first set of interlocking features. At least one cold core plate is formed defining external features of the heat exchanger plate and at least one second set of interlocking features. A core assembly is assembled where each hot core plate is directly interlocked to at least one cold core plate. A wax pattern is formed with the core assembly with an external shell formed over the wax pattern. The wax pattern is removed to form a space between the core assembly and the external shell. The space is filled with a molten material. Once the molten material has solidified, the external shell and the core are removed.
