A plate type heat exchanger is provided to increase a contact area with air by forming plural plates having inclination and to thereby improve heat-exchanging efficiency. A plate type heat exchanger comprises plural plates(1); and tubes(2) penetrated through the plate. Plural plates are faced to each other as one pair disposed adjacent to an elongation line of a profile of the tubes and inclined to a predetermined angle to be shaped of the whole plates as serration so as to increase a contact area between the plates and the tubes and an air contact area between the plates and air. The plates are arranged in a row longitudinally along the tubes to form the plate type heat exchanger. |
