Abstract:
A radial flow heat exchanger comprising:a. a longitudinal axis;b. a plurality of first passages for transporting a first fluid;c. a plurality of second passages for transporting said first fluid;d. a plurality of third passages for transporting a second fluid;e. a plurality of fourth passages for transporting said second fluid;f. wherein each of said first plurality of passages, said second plurality of passages, said third plurality of passages and said fourth plurality of passages surround said longitudinal axis and extend in a direction so as to have a radial change in direction, as measured along radii of said longitudinal axis, divided by a tangential change in direction, as measured tangentially to said radii, that is greater than 10%; andg. further wherein at least one passage in said first plurality of passages, said second plurality of passages, said third plurality of passages and said fourth plurality of passages is constructed such that a first interior portion in said at least one passage lying along a first axis within said at least one passage extending radially to said longitudinal axis is in fluid communication along a major portion of its length with a second interior portion in said at least one passage lying along a second axis within said at least one passage extending radially to said longitudinal axis, with said first axis and said second axis subtending an angle of at least 10.degree..
