DE-EE0007680

Advanced Serpentine Heat Exchangers to Minimize the Number of Joints and Leakage in HVAC&R Systems

(2017 – 2020)

Project Members: Optimized Thermal Systems, Brazeway, Sub-Zero, Virtus Precision Tubes, Heat Transfer Technologies

The Serpentine Aluminum heat exchanger with "dog-bone" fins has just one inlet and one outlet, with a continuous tube connecting the two. Thus, the unit has only two brazed joints.
