AB - The heat exchanger is a devise used for transferring thermal energy between  two or more different temperatures. The widespreadly used heat exchanger can  only achieve heat exchange between two substances. In this paper, a coupled  heat exchanger is proposed, which includes a finned heat exchanger and a  double pipe heat exchanger, for multiple heat exchange simultaneously. An  experiment is conducted, showing that the average heating capacity increases  more than 35%, and the average heating efficiency increases more than 55%,  compared with the ordinary air-source heat pump.
