Title:
FABRICATION METHOD FOR MAKING BRAZED HEAT EXCHANGER WITH ENHANCED PARTING SHEETS
Document Type and Number:
WIPO Patent Application WO/2012/082540
Kind Code:
A3
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 500°C for an extended period of time and then elevating the temperature to 590° to 600°C.
