Heat exchanger for exchange of heat between gases

摘要

The heat exchanger is for use in a shaft-like casing. Fresh air is heated by exhaust air from the rooms. It consists of a rolled insert consisting of a mat of several parallel spaced-out tubes with thin crossed stainless steel braids between them in the shaft. The intermediate cavities (5) between the tubes at the ends of the shaft are filled with a sealing mass. The shaft ends have narrowing tube connectors for the input and output of fresh and exhaust air
