<p>PROBLEM TO BE SOLVED: To provide a water flow generating device which does not require supply of driving energy such as electric power and the like from outside, and which is hardly affected by change of weather.SOLUTION: A water flow generating device includes: a heating side sealed container 4 and a cooling side sealed container 5 in which a high-pressure liquefied gas in a gas-liquid mixed state is filled; an evaporator 6 connected to the sealed container 4; a condenser 7 connected to the sealed container 5; reciprocating drive means 9 communicating with the sealed container 4 and connected to the sealed container 4 via flow passage change means 8; gas phase flow passages 13, 21, 23 for connecting the reciprocating drive means 9 and the condenser 7 via the flow passage change means 8; liquid phase flow passages 14, 16 for connecting the sealed container 5 and the evaporator 6; a drive shaft 19 for reciprocating being interlocked with the reciprocating movement of the reciprocating drive means 9; and water flow generation fins 31, 32, 33 accommodated under water and pivotally supported by the drive shaft 19 in a freely tiltable manner. The evaporator 6, the flow passage change means 8 and the reciprocating drive means 9 are heated at the same temperature as the sealed container 4.</p> |
