Kaori's brazed type heat exchanger consists of a series of thin and corrugated stainless steel plates. These plates are compressed and brazed together with copper or nickel depending on the application. This creates flowing channels between plates, with one fluid in odd number channels and the other in the even number channels, thus reaching the purpose of heat exchanging.Different from the gasket seal type, brazing type uses soldering material (copper or nickel depending on the application) to seal the exchanger. By applying high temperatures in the vacuum environment at the manufacturing process, it melts down the soldering material to form the seal between each of the plates.
