Heat exchanger, for heat recovery, has a heat transfer dividing wall between the channels for the hot fluid flow and the receiving fluid flow, with passages in the wall to give a compact structure and a low flow resistance

摘要

The heat exchanger (4) has at least one initial channel for a flow of fluid (1) to deliver heat, and a second channel for a flow of fluid (2) to receive the heat. At least one heat transfer wall (3) is between the channels, with at least one fluid passage (1a,1b) in the wall. The channel dividing wall can be porous, e.g. of a ceramic material.
