The heat exchanger 1 adopts a double-layer tubular structure, the outer layer of the heat exchanger 1 is a heat exchange pressure-resistant bin, and the shell of the heat exchanger is a metal pressure-resistant pipe, so that heat conduction is convenient. The outer layer of the heat exchanger 1 is a medium cavity which is a rubber hose. The rubber hose is arranged along the axial direction of the metal pressure-resistant pipe, and the phase-change material 11 is filled between the inner wall of the metal pressure-resistant pipe and the outer wall of the rubber hose. The phase change material 11 can catch the sea water temperature change, utilizes the rubber hose to keep apart phase change material 11 and medium, and 11 volume changes back of phase change material act on the medium in the rubber hose, promptly: as the aircraft sinks, the seawater cooling phase change material 11 is solidified, the volume is reduced, and the pressure on the rubber hose is reduced; as the aircraft floats upwards, the seawater warming phase change material 11 melts, the volume is increased, and the pressure on the rubber hose is increased.
The inner storage cavity 2 and the outer storage cavity 3 are both flexible storage cavities, and leather bags can be adopted in practical application. The heat exchange pressure resistant bin and the outer storage cavity 3 of the heat exchanger 1 are both positioned in the external environment of the aircraft, such as seawater; the inner storage chamber 2, the accumulator 4, the hydraulic motor 5, the generator 6, the battery 7, the media tank 8 and the battery management module 10 are all located inside the aircraft.

When the vehicle is suspended under water, a valve between the accumulator 4 and the outer storage chamber 3, hereinafter referred to as valve number two, is opened. The internal pressure of the energy accumulator 4 is greater than the pressure of seawater borne by the outer storage cavity 3, so that a medium flows from the energy accumulator 4 to the outer storage cavity 3, the volume of the outer storage cavity 3 is increased, the buoyancy is increased, and the aircraft floats upwards. And when the buoyancy is equal to the gravity, the second valve is closed, and the aircraft floats near the water surface.
In the floating change process, the phase change material 11 in the heat exchange pressure-resistant bin of the heat exchanger 1 gradually melts with the floating of the aircraft and the pressure on the rubber hose is increased, so that the medium flows into the energy accumulator 4 from the medium cavity through the one-way valve.
2. The electric energy driving method realizes fine adjustment of the position of the aircraft and rapid adjustment of the position, and specifically comprises the following steps:
when the aircraft sinks to the depth close to the underwater target, the battery management module 10 controls the pump 9 to be started, and micro-pumps the medium in the medium box 8 into or out of the outer storage cavity 3, so that the volume of the outer storage cavity 3 is finely adjusted, the buoyancy of the outer storage cavity 3 is finely adjusted, and the fine adjustment of the position of the aircraft is finally realized.

3. The method for converting the temperature difference energy into the electric energy comprises the following steps:
the valve at the fluid inlet of the hydraulic motor 5, i.e., valve number one, is opened. The pressure in the energy accumulator 4 is greater than the pressure in the inner storage cavity 2, the medium actively flows from the energy accumulator 4 to the inner storage cavity 2, when the medium flows through the hydraulic motor 5, the hydraulic motor 5 is driven to rotate, the generator 6 is driven to generate electricity, and the conversion from temperature difference energy to electric energy is realized. When the pressure of the energy accumulator 4 is reduced to an initial value, the first valve is closed, and the power generation is finished. At this point the volume of medium in the inner storage chamber 2 is just equal to the initial volume, completing one working cycle.
