Magnetic Condensing System for Cryogenic Engines

  • :

Patent number: EP 1 367340 A3
Abstract
A method and apparatus is provided for generating an artificial heat sink below ambient temperature for a cryogenic condenser by isothermally magnetizing a paramagnetic fluid and removing the magnetic field thereby creating a temperature drop in the fluid by the magentocaloric effect. The heat of magnetization is converted into mechanical work by initially placing the fluid (10) inside a sealed chamber (12) with a door that opens to a conduit (14) leading into the bore of a superconducting solenoid (18). When the solenoid (18) is energized with current, it creates a strong axial magnetic (20) field that exerts magnetic attractive forces on the fluid (10) inside the chamber (12). When the fluid (10) is released by opening the door, it is accelerated through the conduit (14) toward the superconducting solenoid (18) where it becomes magnetized by the increasing strength of the magnetic field (20). By mounting a nonmagnetic urbine inside the conduit (14) between the solenoid (18) and the chamber (12), the kinetic energy of the accelerating flow stream, which is equal to the heat of magnetization, is converted into mechanical work thereby achieving isothermal magnetization. By removing the magnetic field after the fluid enters the bore of the solenoid, a temperature reduction is achieved thereby enabling the fluid to absorb heat in a cryogenic condenser.

Abstract
A method and apparatus is provided for generating an artificial heat sink below ambient temperature for a cryogenic condenser (32) by isothermally magnetizing a paramagnetic fluid and removing the magnetic field, thereby creating a temperature drop in the fluid by the magentocaloric effect. The heat of magnetization is converted into mechanical work by initially placing the fluid inside a sealed chamber (80) with a door (76) that opens to a conduit (70) leading into the bore of a superconducting solenoid (72). When the solenoid (72) is energized, it creates a strong axial magnetic field that exerts magnetic attractive forces on the fluid. When the fluid is released by opening the door (76), it is accelerated through the conduit (70) toward the superconducting solenoid where it becomes magnetized by the increasing strength of the magnetic field. By mounting a non-magnetic turbine (120) inside the conduit between the solenoid and the chamber, the kinetic energy of the accelerating flow stream, which is accelerating flow stream, which is equal to the heat of magnetization, is converted into mechanical work, thereby achieving isothermal magnetization. By removing the magnetic field after the fluid enters the bore of the solenoid, a temperature reduction is achieved thereby enabling the fluid to absorb heat in a cryogenic condenser.
