Wave power generation system

A wave power generation system comprising:

• a hydraulic pump device configured to operate by force of a wave to discharge an operating liquid to a main passage;
• a hydraulic motor device configured to be rotated by the operating liquid flowing through the main passage;
• a power generator configured to be driven by the hydraulic motor device to generate electric power;
• and
• a heat exchanger device configured to perform heat exchange of the operating liquid, wherein
• the heat exchanger device includes
• a heat exchange motor device connected to the main passage through a sub passage and configured to be operated by the operating liquid introduced through the sub passage,
• a refrigerant pump device driven by the heat exchange motor device and configured to pump up sea water from the sea and discharge the sea water as a refrigerant liquid, and
• a heat exchanger to which the refrigerant liquid discharged from the refrigerant pump device and the operating liquid are introduced, the heat exchanger being configured to perform heat exchange between the refrigerant liquid and the operating liquid to cool the operating liquid.
