Heat exchanger for use as circulating air-exhaust gas-heat exchanger or as fresh air-exhaust gas heat exchanger, consists of heat transfer body which is made from heat conducting embedding material

摘要

The heat exchanger consists of heat transfer body which is made from a heat conducting embedding material (3). The embedded pipes (1,2) are provided for two fluids in the embedding material .The heat flows for balancing the temperature difference between the fluids through the wall of the pipes and embedding material. The pipes are commercial drinking straw, particularly from polypropylene, polyethylene or polyvinyl chloride.
