Phase-change buoyancy engine based on microwave heating

Abstract

The invention discloses a phase-change buoyancy engine based on microwave heating. The phase-change buoyancy engine comprises a buoyancy generating unit and a temperature control unit. The buoyancy generating unit comprises a clamp, a sealing ring, a casing, a heat insulating material, a phase change material, a base and a watertight connector. The temperature control unit comprises a magnetron, afilter conduit, a metal reflector, a metal heat-radiating plate, a power supply and a switch. The phase-change buoyancy engine has the advantages that a microwave heating device is used for rapid anduniform heating, and accordingly, the problem that phase change materials in the prior art are heated slowly and unevenly is solved.

Description

technical field [0001] The invention relates to a buoyancy engine, in particular to a phase-change buoyancy engine which utilizes microwaves to participate in temperature control. Background technique [0002] The buoyancy engine is an important subsystem of the underwater vehicle, which controls its floating or submerging by changing the net buoyancy of the submersible. Traditional buoyancy engines use hydraulically driven pistons to change the volume of water displaced by the submersible. This solution uses a complex hydraulic system and consumes a lot of electrical energy. [0003] Phase change materials will change their own volume when changing between solid and liquid phases. Using this property of phase change materials, phase change buoyancy engines can be made. Compared with traditional hydraulic power buoyancy engines, this type of engine has the advantages of compact structure, light weight, and low vibration and noise. [0004] In order to change the buoyancy o...
