Abstract

The invention discloses a phase transformation buoyancy engine cooled by a heat pipe. The phase transformation buoyancy engine is composed of a buoyancy generating unit and a temperature control unit.The buoyancy generating unit is composed of a hoop, a seal ring, a shell, an insulating material, a phase transformation material, a base and a watertight connector. The temperature control unit is composed of a heat-dissipating metal plate, the heat pipe, an electric heating wire, a direct current power supply and a switch. The phase transformation buoyancy engine is cooled efficiently by meansof the heat pipe, so that the cooling speed of a phase transformation material is improved, and a cooling process without energy consumption is achieved. In addition, the phase transformation buoyancyengine disclosed by the invention also has the advantages of being good in insulating effect, simple and stable in structure, light in weight and the like.

Description

technical field [0001] The invention relates to a buoyancy engine, in particular to a phase change buoyancy engine which utilizes a heat pipe 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. The traditional buoyancy engine uses a hydraulically driven piston to change the volume of the submersible's drainage. 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 of ...
