Abstract:
1. An air to air heat exchanger comprising in combination: (a) a plurality of stacked spread apart plates; (b) a plurality of sets of clips intersect adjacent plates to define a space therebetween and to define an outline of each of a plurality of curvilinear air flow paths intermediate adjacent plates; (c) a length of compressible material generally coincident with each outline to define the boundaries of the air flow paths intermediate each pair of adjacent plates; (d) a first path of said plurality of paths between a first pair of said adjacent plates including a first end section curved in a first direction, a second end section curved in a second direction, said second direction being opposite to the first direction and a first straight center section interconnecting said first and second end sections; (e) a second path of said plurality of paths between a second pair of said adjacent plates including a third end section curved in the second direction and generally coincident with said first end section, a fourth end section curved in the first direction and generally coincident with said second end section and a second straight section generally coincident with said first straight section and interconnecting said third and fourth end sections; (f) a first inlet for introducing a first gas to said first end section and exhausting the first gas from said second end section through a first outlet; and (g) a second inlet for introducing a flow of a second gas to said fourth end section and exhausting the second gas from said third end section through a second outlet to provide counter flow.
