Project Term:

Technology Description:

The University of Maryland (UMD) will leverage recent advances in additive manufacturing to develop a next-generation air-cooled heat exchanger. The UMD team will assess the performance and cost of current state-of-the-art technology, including innovative manufacturing processes. The team will then utilize computer models to simulate a wide-range of novel heat exchanger designs that can radically enhance air-side heat transfer performance. The team will then physically build and test two 1 kilowatt (kW) prototype devices. If successful, these heat exchangers would enable new, highly-efficient dry cooling of steam condensers that could eliminate evaporative water losses from power plant cooling. Advances in efficient air-side cooling could also have significant spillover benefits in aerospace, automobile, air-conditioning and refrigeration, electronics cooling, and chemical processing.
