Abstract:
1. A heat exchanger including: a heat exchanger section having a plurality of parallel tubes running from a first end thereof to a second end thereof in a close-spaced geometrical pattern; a solid heat-conductive matrix in contact with the plurality of parallel tubes; a first manifold coupled to a first end of the heat-exchange section and fluidly coupled to first ends of a first group of tubes; a second manifold coupled to a distal end of the first manifold and isolated from the first manifold by a first bulkhead disposed at an acute angle with respect to the first end of the heat-exchange section, the second manifold fluidly coupled to first ends of a second group of tubes alternating with the first group of tubes, the first ends of the second group of tubes extending through the first manifold and passing through the first bulkhead to reach the second manifold; a third manifold disposed at a second end of the heat-exchange section and fluidly coupled to second ends of the first group of tubes; and a fourth manifold coupled to a distal end of the third manifold and isolated from the third manifold by a second bulkhead disposed at an acute angle with respect to the second end of the heat-exchange section, the fourth manifold fluidly coupled to second ends of the first group of tubes, the second ends of the first group of tubes extending through the third manifold and passing through the second bulkhead to reach the fourth manifold.
