Compact recuperative heat transfer system - has low and high conductivity partitions ensuring high heat exchange rate, using copper and steel

摘要

The recuperative heat transfer arrangement is used for heat exchange between two separate media. The chambers have common partition walls and inlet and outlet openings at opposite ends. Large heat transfer surface areas are obtained from small volume. The length between inlet and outlet is reduced for high temperature differences. The partition wall has in succession in the main flow direction of the media, series arranged areas of high conductivity (4) and areas of lower conductivity (5). The regions of high thermal conductivity (4) are arranged as ribs across the main flow direction of the media in the free spaces of the chambers (1, 2, 3). The regions of high thermal conductivity (4) are made of copper. The regions of lower thermal conductivity (5) are made of stainless steel.
