Description

technical field [0001] The invention belongs to the field of ocean temperature difference energy conversion, and specifically relates to an energy conversion hydraulic system that collects ocean temperature difference heat energy through phase change power heat pipes, converts the volume change of phase change materials into mechanical energy of a hydraulic system, and then converts it into electrical energy. Background technique [0002] Most of the marine detection equipment is powered by batteries to maintain the battery life and detection capabilities of the marine detection equipment. Marine environmental detection equipment that uses marine environmental energy as its energy source mainly uses solar energy, wave energy, wind energy, and temperature difference energy as energy sources to provide energy demand for marine detection equipment. [0003] In the field of ocean temperature difference energy conversion, relatively warm tropical water currents are usually used t...

AI Technical Summary

Problems solved by technology

[0004] This battery power supply method has certain defects, mainly in the following aspects: First, the battery storage energy is limited, which limits the endurance and detection capabilities of marine detection equipment

Second, energy sources such as solar energy, wave energy, and wind energy are suitable for marine detection equipment working near the sea surface, but not for profile movement marine detection equipment

Third, the existing ocean temperature difference power generation circulation system is too large, requiring a large amount of circulating liquid, and the power generation equipment is not convenient for ocean detection equipment to carry
