ROLLED MAT HEAT EXCHANGER AND METHOD OF MANUFACTURE

摘要

A method of manufacturing a bundled mat construction (22) for an extracorporeal blood circuit heat exchanger (20) includes attaching a leading edge of a first capillary tube mat segment to a first side of a mandrel. A leading edge of a second capillary tube mat segment is attached to a second side of the mandrel. The first side is diametrically opposite the second side. The mandrel is rolled relative to the mat segments to generate a bundled mat construction (22). Radial layers of the bundled mat construction are symmetrical relative to a central axis of the mandrel.
