Abstract:
A heat exchanger assembly, comprising:a plurality of first fluid pathway layers that allow fluid to flow in a first direction through the assembly; a plurality of second fluid pathways layers that allow fluid to flow in a second direction through the assembly; a parting sheet separating each of the fluid pathway layers; and a plurality of first closure bars associated with the first fluid pathway layers, the first closure bars having a solid surface that is operative to guide fluid through the first fluid pathways in the first direction and having a reinforcing portion extending at least partially into the first fluid pathways, each reinforcing portion having a modified flow passage that allows fluid flow in the first direction, each reinforcing portion having two reinforcing members spaced apart from each other, a distal edge of the reinforcing members being spaced from the solid surface a varying distance along a length of the reinforcing members, a distance between the distal edges and the solid surface being greatest near one end of the reinforcing members.
