[0019] The present invention will be further described below in conjunction with the drawings.

[0020] Please refer to Figure 1 , which shows a mechanical energy conversion device of the present utility model that utilizes the environmental temperature difference. The device includes: a fluid storage device 1, a fluid heating device 2, a power device 3, and a fluid cooling device 4.

[0021] Among them, the fluid storage device 1 at least includes: a liquid storage tank 101 for storing fluid and an outlet valve 102 provided on the outlet pipeline of the liquid storage tank 101. The liquid storage tank 101 stores the cooled fluid medium, and its capacity meets the continuous working fluid supply of the entire mechanical energy conversion device of the present utility model, that is, it is sufficient to supply the mechanical energy output of the power device 3 before the cooled fluid flows back to the liquid storage tank 101.

[0022] The fluid heating device 2 at least includes: a heater 201 for heating a fluid medium and a diversion pump 202 disposed on the pipeline between the outlet valve 102 and the heater 201. The diversion pump 202 introduces the liquid stored in the liquid storage tank 101 into the heater 201, and the high-temperature liquid after heating flows out through the liquid and enters the power device 3.

[0023] The power device 3 at least includes: a high-pressure tank 301 that can withstand high temperature and high pressure and is connected to the heater 201 through a pipeline, an impeller device 302, and a torque output shaft 303. After the high-temperature fluid continuously enters the high-pressure tank 301, high-temperature and high-pressure liquid is formed. The high-pressure fluid forms a high-pressure and high-speed liquid flow at the outlet of the high-pressure tank 303, impacting the blades of the impeller device 302, and the impeller device 302 drives the torque output shaft 303 to rotate in the same direction to complete torque output. After the fluid is decompressed and decelerated during the flow process from the outside to the inside of the impeller device 302, the fluid flows into the output valve 304.

[0024] The fluid cooling device 4 at least includes: a cooler 401 for cooling the fluid connected to the impeller device 302 through a pipeline and a stop valve 402 disposed on the connecting pipeline between the cooler 401 and the liquid storage tank 101. After the fourth box body 402 cools the fluid flowing out of the power device 3 to the normal temperature state, it flows into the liquid storage tank 101 through the stop valve 402.

[0025] Furthermore, two sets of fluid heating devices 2 are provided between the power device 3 and the fluid storage device 1, and the power device 3 includes two high-pressure tanks 301 connected to the fluid heating device 2 through pipelines; the fluid storage device 1 is provided with two pipelines for fluid outflow and outlet valves 102 are respectively arranged along the fluid outflow direction.

[0026] Through the present utility model, the circulation of the fluid in the device is realized. During this process, the fluid heating device 2 transfers heat energy to the fluid medium to form the kinetic energy of fluid flow and the potential energy of increased pressure, and the impeller device 3 converts the kinetic energy and potential energy of fluid flow into the output mechanical energy, thereby realizing power output.

[0027] The fluid medium of the present utility model can be selected from liquid metal or metal alloy, and fluids that are easy to undergo low-temperature gas-liquid phase transformation;

[0028] The fluid heating device 2 can be used in cooperation with a device that can generate a large amount of waste heat for heat exchange or directly heated or heat exchanged by a device that can form high temperature using solar radiant energy;

[0029] The fluid cooling device 4 can cool the fluid medium of the present utility model in an environment that is easy to form a cold source such as a large natural gas storage station, a liquefied gas station, and liquid nitrogen and liquid oxygen; or the mechanical energy conversion device of the present utility model can be set through the natural temperature difference between heat and cold formed in industrial production.
