Countercurrent heat exchanger

摘要

In known countercurrent heat exchangers for the aeration and deaeration of stables, the foul-air guidance does not always run vertically, since the lower ends of the throughflow ducts for the foul air are curved towards one side. As a result, foreign bodies and condensation water collect in the curves. The novel countercurrent heat exchanger is to avoid obstruction by means of vertical foul-air guidance. The throughflow ducts (22) of the novel countercurrent heat exchanger serve to supply the fresh air (52) and open at their upper ends (28) into sucking-in ducts (30), each of which connects a row of throughflow ducts (22) and is laterally linked to supply-air openings (46) of the heat exchanger constructed as a chimney (10). The countercurrent heat exchanger is particularly suitable for the aeration and deaeration of stables.
