HEAT EXCHANGER FOR COOLING MULTIPLE FLUIDS

Abstract:

A heat exchanger having a stack of nested shells joined to a base plate includes two coolant manifolds and four fluid manifolds extending through the stack. The coolant manifolds extend the entire length of the stack in the stacking direction. Two of the fluid manifolds extend from one end of the stack to an intermediate location along the stacking direction, and the other two fluid manifolds extend from the other end of the stack to the intermediate location. Fluid transfer conduits extend through the stack, from a face of the base plate opposite the stack to the fluid manifolds at the end of the stack opposite the base plate, in order to transfer fluid to and from fluid flow passages extending between those fluid manifolds at that end of the stack.
