A brazing method is developed for high efficiency microchannel heat plate heat exchangers for waste heat recovery. Prototype elements for these heat exchangers are fabricated by laser machining 316 stainless steel, and bonding with AMS 4777 brazing alloy. Specifications require that the heat exchangers withstand in excess of 5000psi of fluid pressure, tested with a high pressure water system that was developed for this project. Due to the costly nature of the pressure test, a model is developed to correlate braze performance in the heat exchanger with data from inexpensive mechanical tensile and peel tests. The model predicts that the maximum peel load per specimen width will be 342lbs/in and a maximum pressure of 7200psi in the heat exchanger. The highest value from the experiments is 330lbs/in for peel load and 6467psi in the pressure test, 97% and 90% of their respective theoretical values.
