Embodiment 1

[0023] Such as figure 1 As shown, the device is composed of a heating device 2 and a heat conversion device 8. The heating device utilizes the existing solar heating device to heat the heat exchange medium in the heating device through the solar heating device.

[0024] The thermal power conversion device 8 is made up of a closed container with a vacuum state inside. The closed container is divided into two vacuum closed rooms, an upper airtight chamber 9 and a lower airtight chamber, by a partition 10 inside the airtight container. The upper airtight chamber is equipped with a corresponding Change heat medium. The evaporation chamber 14 is inserted into the hole on the partition, and the outer wall of the evaporation chamber is airtightly connected with the hole on the partition. A heat pipe 13 is inserted at the bottom of the evaporation chamber, and the outer circle of the heat pipe is airtightly connected with the bottom of the evaporation chamber. The upper end of the h...

Embodiment 2

[0035] On the basis of above-mentioned embodiment 1, in order to further improve the performance of this device, as figure 2 As shown, an energy storage device 18 is added between the heating device 2 and the heat conversion device 8, and the circulation pump I17 is changed into a compressor 22.

[0036] The energy storage device is composed of a heat exchange airtight container and a heating device. A heat exchange medium is installed in the heat exchange airtight container. A heat exchanger 19 and a heat exchanger I21 are installed in the heat exchange airtight container of the energy storage device. The heat exchanger The liquid outlet pipe 1 and the liquid return pipe I20 are connected to the heating device 2, and the heat exchanger I is connected to the heat absorbing device 5 through two pipelines; Machine 22, the suction port of the compressor is connected with the liquid outlet of the heat absorbing device, and the exhaust port of the compressor is connected with the ...

Embodiment 3

[0039] In the above-mentioned embodiment 1 or 2, the air flow power generation device of the thermal power conversion device can be replaced by a structure equivalent to an internal combustion engine composed of a cylinder, a piston, a crank linkage and an exhaust port on the cylinder, and the nozzle installed at the upper end of the evaporation chamber 34 is fixedly installed in the cylinder. When the pressure control valve on the nozzle is opened, the high-pressure gaseous phase-change heat medium pushes the piston to move, and drives the crank connecting rod mechanism to rotate. At the same time, the exhaust port on the cylinder opens and the phase-change heat medium into the upper airtight chamber.

[0040] The above-mentioned structure is an improvement on the basis of the existing internal combustion engine. The high-pressure gaseous phase-change heat medium ejected from the nozzle is used to push the piston to move, and the heat is converted into rotational mechanical en...
