Abstract

PURPOSE: To suppress mechanical vibration and noise by providing a condenser, an expansion valve, an evaporator and a fluid pump comprising a superconducting coil, a pair of electrodes and a DC power supply and adding an alkaline salt to a refrigerant. CONSTITUTION: A strong magnetic field is generated between superconducting coils 10, 11 by inducing a current between electrodes 12, 13 in refrigerant piping 8a thus producing a refrigerant flow by Lorentz force. Ionization of fluid in the piping 8a through the electrodes 12, 13 is accelerated by an alkaline salt added to refrigerant 15. Consequently, a current flows easily between the electrodes 12, 13 to enhance Lorentz force thus realizing an efficient fluid pump 9 free from mechanical vibration.

The operation of the cooling device configured as described above will be explained below. The refrigerant 16 in the refrigerant pipe 8a of the fluid pump 9 section is ionized by the positive and negative electrodes 12 and 13, and is transferred from the electrode 12 to the electrode 13.
Current flows towards. On the other hand, superconducting carp Iv1o,
Between the electrodes 12 and 13, a strong magnetic flux is generated by the superconducting coil from the superconducting coil/I/1o toward the superconducting coil 11. Therefore, the current flowing between the electrodes 12 and 13 and the superconducting coil/I/10 The flowing magnetic flux creates a Shirolentz force, causing the ionized refrigerant 16 to move toward the condenser, creating a flow of refrigerant 16 toward the condenser and expanding between the condenser 2 and the evaporator 4, which circulate through the cooling system. Because it goes through valve 3,
The refrigerant 16 has a high pressure on the condenser 2 side and a low pressure on the evaporator 4 side, so a cooling cycle can be formed in which the condenser 2 radiates heat and the evaporator 4 absorbs heat. Furthermore, the refrigerant 16 contains C8 salt. Since fine particles are added, ionization by the electrodes 12 and 13 is promoted, making it easier for current to flow between the electrodes, thereby strengthening the Lorentz force, increasing the refrigerant flow rate, and improving performance. In addition, since the flow of the refrigerant 16 is generated electromagnetically by the Lorentz force, no mechanical vibration noise is generated.Furthermore, since the flow is generated with a continuous and constant force, there is no pressure pulsation of the refrigerant, and the refrigerant piping system Since it is possible to prevent the generation of vibration and noise at Therefore, the flow rate of the refrigerant can be increased due to the increase in the Lorentz force, the capacity is improved, and an efficient cooling system can be formed. Since it changes, superconducting carp A/1
In addition to being able to control the flow rate of the refrigerant 15 by controlling the current flowing through the electrodes 12 and 11, the flow rate of the refrigerant 15 can also be controlled by controlling the voltage between the electrodes 12 and 13, making capacity control extremely easy. be.

A superconducting coil, a pair of electrodes located in the refrigerant pipe corresponding to the superconducting coil, and a DC power supply connected to the electrodes, and by adding an alkali metal salt to the refrigerant, By generating an electric current in the refrigerant between the electrodes in the refrigerant pipe and further generating a strong magnetic field through the superconducting coil, a flow of the refrigerant is generated by the Schiller-Lenz force, thereby forming a fluid pump free of mechanical vibrations. Furthermore, since the refrigerant flow is generated with a continuous and constant force, there is no pressure pulsation in the refrigerant, and vibration noise in the refrigerant pipe system can be prevented, resulting in extremely effective noise reduction. Moreover, by adding an alkali metal salt to the refrigerant, it is possible to make the current flow between the electrodes easier, so the flow rate of the refrigerant can be increased by increasing the Lorentz force, improving the capacity and forming an efficient cooling system. Furthermore, the capacity can be easily controlled by controlling the voltage flowing through the superconducting coil and the voltage between the electrodes.
