<p>A casting method involves casting a metal heat exchanger by way of a high pressure die casting process on a core, the core having a salt component soluble to a water solvent and a metal component non-soluble to the solvent. The soluble salt core component is integrally cast on the surface of the metal core component to form a desired shape. During casting the insoluble core component and the soluble core component are directly in contact with molten metal and remain in place within the solidified metallic casting. The method further comprises dissolving the soluble portion of salt with the water solvent to form one or more cavities and/or channels of the desired shape in the heat exchanger casting.</p> |
