ABSTRACT:
A laminated spiral heat exchanger (10) in accordance with the invention includes a heat conductive top laminate (30); a heat conductive bottom laminate (36), at least one spiral heat conductive laminate (42), the laminates being joined together to form a heat exchanger core; at least one spiral channel (18) disposed within at least one spiral laminate; a first fluid port (20) coupled to each spiral channel at a first radius with respect to a center of the spiral heat exchanger; and a second fluid port (24) coupled to each spiral channel at a second radius with respect to the center point of the spiral heat exchanger which is greater than the first radius.
