Abstract
Disclosed is a heat exchanger comprising a boiling passage and cooling passage defined by opposite sides of metal walls. Layers of brazing material between the metal walls and a spacer member bond components of the heat exchanger together. It has been found that good quality brazed joints can be made by modifying the brazing thermal cycle to first employing a temperature of about 500° C. for an extended period of time and then elevating the temperature to about 590° to 600° C.
