In March 2023, the VPE & VPE Thermal teams completed the manufacturing of a Hybrid Dry Cooler System for sCO2 Power Cycles in CSP Applications.  This novel dry cooler system combines stainless steel microchannel heat exchanger plates with stainless steel fins.  To achieve this hybrid heat exchanger, the plates are first diffusion bonded and then later vacuum brazed to the fins.  This program aims to improve the current state-of-the-art (SOA) for dry cooling technology for remote, arid CSP installations.
