HEAT EXCHANGER WITH UNDULATING PLATES

Abstract:

A heat exchanger includes a first plate defining a first plurality of undulations that extend along a first axis and a second axis, and a second plate defining a second plurality of undulations. The second plate is spaced apart from and coupled to the first plate to define a first fluid flow passage. A first flow area of the first fluid flow passage is constant from a first inlet to a first outlet. The heat exchanger includes a third plate defining a third plurality of undulations. The third plate is spaced apart from and coupled to the second plate to define a second fluid flow passage. The second fluid flow passage is discrete from the first fluid flow passage. A second flow area of the second fluid flow passage is constant from a second inlet to a second outlet.
