Manufacturing of heat exchangers for the HVAC&R industry, although well established, is capital and labor intensive. Additively manufactured heat exchangers are emerging as an alternative technology to traditional manufacturing. In this seminar, we present some ongoing research highlighting recent developments improving heat exchanger performance and producing more compact designs. The current high cost of 3D printing is addressed by exploring intermediate enhanced conventional manufacturing strategies. Process techniques are also presented that improve the performance of additively manufactured heat exchangers.
