ABSTRACT:
The problem of designing an impingement plate type heat exchanger (10) for exchanging heat between a pair of fluids wherein one of the fluid is a gas, such as air, is solved by providing a stack of plates (12) including impingement orifice plates (14), spacer plates (16) and manifold plates (18, 20). The impingement orifice plates and the spacer plates cooperate to define first and second flow paths (F and E) generally parallel to each other and perpendicularly through the plates for the liquid and the gas, respectively. The first flow path (F) for the liquid is tortuous through orifices (56) of the plates. The manifold plates define flow passages (24) for distributing the liquid to the first tortuous flow path. The flow passages in the manifold plates extend generally parallel to the plates.
