Definitions

  • a self-cooling liquefied air engine comprises a high-pressure tank, a low-pressure cooler, a jet pipe, an intermediate-temperature cooler, a heat exchanger and a turbine.
  • the liquefied air in the high-pressure tank absorbs external heat and boils to produce high-pressure steam.
  • the pressure used in industry can now reach a supercritical state.
  • the high-pressure tank produces high-pressure steam, which is sucked into the steam of the low-pressure cooler through the jet pipe, so that the low-pressure cooler maintains a relatively low pressure. At low pressure, the boiling point is reduced, resulting in a relatively low temperature.
  • the steam enters the medium-temperature cooler to cool the steam that has done work. During the cooling process, the steam absorbs heat and expands, and then enters the heat exchanger to absorb external heat to further increase the temperature and expand.
  • the expanded steam enters the turbine to do work and output power.
  • the steam that has done work returns to the medium-temperature cooler and the low-pressure cooler to be cooled and liquefied again, forming a cycle.
  • Fig. 1 is a schematic diagram of the structure of the present invention, in which: 1. high pressure tank, 2. low pressure cooler, 3. jet pipe, 4. medium temperature cooler, 5. low temperature cooler, 6. heat exchanger, 7. turbine, 8. pressure relief valve, 9. high pressure pump, 10. vapor-liquid separator, 11. steam pipe, 12. exhaust gas pipe, 13. liquid pipe.
  • the high-pressure tank 1 and the low-pressure cooler 2 are both filled with liquefied air.
  • the high-pressure steam in the high-pressure tank 1 is ejected at high speed through the jet pipe 3.
  • the low-pressure cooler 2 is kept at a relatively low pressure, and the boiling point will be reduced accordingly.
  • the temperature after boiling will not be higher than the boiling point, thereby cooling and liquefying the high-boiling-point steam.
  • jet tube 3 can generally inhale several to dozens of times more gas.
  • the low pressure cooler 2 is insulated from the outside world and only absorbs the heat of the exhaust gas. Similarly, as long as the application does not mention the part that absorbs the outside heat, it is insulated from the outside world.
  • the exhaust gas is not discharged directly into the low-pressure cooler 2, but is stored in something like a heat pipe. Maintaining a relatively high pressure, it indirectly exchanges heat with the liquefied air of the low-pressure cooler 2.
  • the steam which still has a certain pressure and temperature after having done work through the turbine 7 is called exhaust gas.
  • the steam generated by the high-pressure tank 1 and the steam generated by the low-pressure cooler 2 are mixed in the jet tube 3 and enter the medium-temperature cooler 4 to cool the exhaust gas with a certain pressure and temperature after doing work.
  • the steam absorbs the heat of the exhaust gas in the medium-temperature cooler 4 and heats up, then enters the heat exchanger 6, absorbs the heat from the outside and further heats up and expands, and then enters the turbine 7 to do work and output power to the outside.
  • the exhaust gas then enters the low temperature cooler 5 and is further cooled by the steam.
  • the functions of the medium temperature cooler 4 and the low temperature cooler 5 are mostly repeated, and the low temperature cooler 5 can be removed.
  • the liquid is separated by the gas-liquid separator 10 and then returned to the high-pressure tank 1 through the high-pressure pump 9.
  • the exhaust gas enters the low-pressure cooler 2, and the liquefied air inside absorbs the exhaust gas heat and boils to produce steam. Because the liquefied air in the low-pressure cooler 2 has a low boiling point, the exhaust gas can be cooled to its own boiling point and liquefied. After the exhaust gas is liquefied, part of the liquid returns to the high-pressure tank 1 through the high-pressure pump 9, and part returns to the low-pressure cooler 2. The exhaust gas that cannot be liquefied is discharged by the pressure relief valve 8.
  • the steam from the low-pressure cooler 2 enters the low-temperature cooler 5 to cool the exhaust gas therein.
  • the steam from the low-pressure cooler 2 is mixed with the steam from the high-pressure tank 1 through the jet pipe 3.
  • the power output device is not limited to the turbine 7, and may be a cylinder or the like.
  • the gas used is not limited to liquefied air, but may also be other cryogenic liquefied gases.

Abstract

Moteur à air liquéfié à refroidissement automatique comprenant un réservoir haute pression (1), un refroidisseur basse pression (2), un échangeur de chaleur (6), un tuyau de jet (3) et un refroidisseur à température moyenne (4). Un gaz haute pression généré par le réservoir haute pression (1) est rapidement éjecté pour aspirer la vapeur du refroidisseur basse pression (2), de telle sorte que le refroidisseur basse pression (2) maintient une basse température, de façon à refroidir un gaz haute température. Le moteur à air liquéfié à auto-refroidissement utilise de l'air liquéfié ayant un point d'ébullition bas pour refroidir l'air haute pression en dessous du point d'ébullition de celui-ci, ce qui permet de re-liquéfier l'air haute pression.
