PURPOSE: A laminate type heat exchanger assembly is provided to easily form plates and extend durable life. CONSTITUTION: A laminate type heat exchanger assembly includes blocking plates. The blocking plates has blocking parts(6) selectively formed on upper parts or lower parts thereof and are interposed between heat exchange tubes(T1,T2,T3,T_L, T_R). The blocking plates close flowing holes(9) on upper parts or lower parts of the heat exchange tubes close to the blocking plates by the blocking parts to change passage of heat exchange fluid connected in side direction of a heat exchanger through the flowing holes of plates comprising the heat exchanger. Inlet holes(5) are formed on upper ends of one sides of the plates of the heat exchange tubes and the blocking plates whose air-tightness is kept by joining surfaces. A heat exchange passage is connected from the heat exchange tube on one end to the heat exchange tube on the other end through the inlet holes and successively connected from the inlet hole of the heat exchange tube on the other side to the flowing hole of the heat exchange tube on one end following the heat exchange tubes between the heat exchange tubes on both ends. Direction of passage is vertically alternated by the blocking parts of the blocking plates.
