Multifluid heat exchanger
A multifluid heat exchanger includes a first tank connected to a second tank through a plurality of fluid conduits. A partition disposed inside the first tank divides an internal space of the first tank into a first space and a second space. The first space is in fluid communication with the second tank through the plurality of fluid conduits. As a result, a first internal fluid may flow from the first space to the second tank, while a second internal fluid may flow through the second space.
