A counter flow heat exchanger with integrated fins and tubes comprises metal plates overlapping with each other. Each of the metal plates has multiple elongated ridges spacing apart from each other. Adjacent metal plates oppositely overlap with each other such that the ridges in pairs form horizontal tubes and multiple connecting tubes on the plates form vertical tubes. A lowermost plate is set on two guide tubes, which are connected to lower ends of the connecting tubes and connected to a fluid pumping unit via a connecting pipe respectively. Thus, fluid inside the heat exchanger flows counter to external air and a better efficiency of heat exchange can be reached effectively.
