PROBLEM TO BE SOLVED: To provide a heat exchanger device capable of generating expansion, evaporation process correlated with condensation and liquefaction of high pressure gas by itself, and capable of maintaining heat balance by a synergistic effect of both generated heat of condensation latent heat and evaporation latent heat during phase change of the high pressure gas. SOLUTION: In the self-balancing condensing and evaporating heat exchanger device, a heat exchange plate is provided in the middle to partition off a primary side and secondary side, both of which are equipped with an inlet and outlet, and it is regarded as a heat exchanger of a composition serially connecting the outlet of the primary side and the inlet of the secondary side by a connection pipe via an expansion valve. High-pressure high-temperature un-condensed gas is introduced into the inlet of the primary side, it is passed through the connection pipe from the primary side, it is decompressed by the expansion valve, the high-pressure high-temperature gas is decompressed and cooled by a throttling expansion effect, it is introduced into the secondary side inlet, a process of cooling the secondary side by the throttling expansion effect to a lower temperature than a condensation temperature of the high-pressure gas is repeated, and an amount of a condensed liquid is increased to maintain the heat balance.
