All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-9, a permanent magnet type magnetic refrigerator using AMR technology as a core comprises a refrigerator main body 1, a mounting base 2 is arranged inside the refrigerator main body 1, a refrigerator inner chamber 3 is arranged inside the refrigerator main body 1, a refrigerator outer wall 4 is arranged outside the refrigerator main body 1, a double-sided permanent magnet pole 5 is arranged inside the refrigerator outer wall 4, a magnetic spring 6 is movably connected to the inner side of the double-sided permanent magnet pole 5, a magnetic field air gap channel 7 is movably connected to the inner side of the refrigerator outer wall 4, one end of the magnetic field air gap channel 7 far away from the refrigerator outer wall 4 is movably connected to a valve pump body 8, one end of the valve pump body 8 far away from the magnetic field air gap channel 7 is movably connected to a cold air pipeline 9, a protection spring group 10 is sleeved outside the cold air pipeline 9, and one end of the cold air pipeline 9 far away, a movable tooth track 12 is movably mounted on the inner side of the mounting block 11, and an electromagnetic gear 13 is meshed on the inner side of the movable tooth track 12.
A circulating sealed electromagnetic space is formed by four groups of sealed movable electromagnetic valves 17 and electromagnetic gears 13; meanwhile, the double-sided permanent magnet poles 5 in the inner cavity 3 of the refrigerator work simultaneously to generate a circulating magnetic field, so that two groups of heat insulation magnetic fields are formed; based on the thermodynamic principle of magnetic refrigeration and the Carnot cycle principle, the temperature of the material is reduced, and heat is absorbed from the outside, so that the refrigeration effect is formed.
A support frame 14 is movably arranged on the outer side of the valve pump body 8. The outer side swing joint of support frame 14 has solenoid valve 15, the one end swing joint that support frame 14 was kept away from to solenoid valve 15 has electromagnetic channel 16, the inside movable mounting of electromagnetic channel 16 has movable solenoid valve 17, the one end swing joint that electromagnetic channel 16 kept away from solenoid valve 15 has conduction magnet 18, the one end swing joint that electromagnetic channel 16 was kept away from to conduction magnet 18 has solenoid 19, the one end fixed mounting that conduction magnet 18 was kept away from to solenoid 19 has electro-magnet 20.
Because the electromagnetic valve 15 and the electromagnet 20 are respectively arranged at the two opposite ends of the moving electromagnetic valve 17, the moving electromagnetic valve 17 moves irregularly and ceaselessly in the electromagnetic channel 16 due to the electromagnetism; meanwhile, because of the irregular movement of the movable electromagnetic valve 17, the electromagnetic gear 13 at the central positions of the electromagnetic valve 15, the movable electromagnetic valve 17 and the electromagnet 20 is subjected to the fluctuation of the magnetic field and also irregularly moves at the inner side of the movable tooth path 12; one circulation sealed electromagnetic space is formed by four sets of moving electromagnetic valves 17 and electromagnetic gears 13 in a sealed manner.
The working principle is as follows: AMR is an active magnetic regenerator technology, and is firstly proposed to establish a room temperature magnetic refrigeration demonstration machine by C.Zimm of American aerospace company in 1996. The refrigerating capacity of 500-600W is obtained under the Tesla magnetic field provided by the superconducting magnet. Then, AMR is commonly used in magnetic refrigerators and becomes a core component of magnetic refrigerators.
When the refrigerator main body 1 is used, the external power supply is continuously electrified, so that the electromagnet 20 and the electromagnetic valve 15 both generate electromagnetism, the electromagnetic valve 15 attracts the movable electromagnetic valve 17 in the electromagnetic channel 16, the outside of the movable electromagnetic valve 17 is provided with a latch matched with the inner side of the electromagnetic channel 16, and the movable electromagnetic valve 17 moves in the electromagnetic channel 16; meanwhile, the electromagnet 20 is conducted through the conducting magnet 18 due to the electromagnetic property thereof, and the moving electromagnetic valve 17 is synchronously attracted, and the electromagnetic valve 15 and the electromagnet 20 are respectively arranged at the two opposite ends of the moving electromagnetic valve 17, so that the moving electromagnetic valve 17 irregularly and ceaselessly moves in the electromagnetic channel 16 due to the electromagnetic property; meanwhile, because of the irregular movement of the movable electromagnetic valve 17, the electromagnetic gear 13 at the central positions of the electromagnetic valve 15, the movable electromagnetic valve 17 and the electromagnet 20 is subjected to the fluctuation of the magnetic field and also irregularly moves at the inner side of the movable tooth path 12; one circulation sealed electromagnetic space is formed by four sets of moving electromagnetic valves 17 and electromagnetic gears 13 in a sealed manner.
Meanwhile, the thermodynamic principle of magnetic refrigeration is as follows: the magnetocaloric effect is a change in the entropy of a magnetic material by an external magnetic field, resulting in a temperature change. In a system with magnetic field intensity of H, temperature of T and pressure of P, the magnetic entropy has a full differential formula as follows:
as for the magnetic pole material, it is known from its basic properties,
the constant value is negative, so in the above formula, dH is less than 0, dT is less than 0, namely, when the material is subjected to adiabatic demagnetization, the temperature of the material is reduced, and heat is absorbed from the outside; dH is more than 0, dT is more than 0, namely, when the magnetization is carried out, the temperature of the material is increased, and heat is released to the outside.
Meanwhile, based on the carnot cycle principle: the Carnot cycle comprises two isothermal processes and two adiabatic processes, wherein in the two adiabatic processes, the system does not exchange heat with the outside, and the total entropy value of the system is kept constant; when the magnetic entropy of the magnetic refrigeration working medium is changed by the magnetic field, the temperature is inevitably changed, so that heat release and heat absorption can be realized in two isothermal processes, and the aim of refrigeration is fulfilled.
A circulating sealed electromagnetic space is formed based on the four groups of movable electromagnetic valves 17 in a sealed shape and the electromagnetic gear 13; meanwhile, the double-sided permanent magnet poles 5 in the inner cavity 3 of the refrigerator work simultaneously to generate a circulating magnetic field; thereby forming two sets of adiabatic magnetic fields; based on the thermodynamic principle and the carnot cycle principle of the magnetic refrigeration, the two groups of adiabatic magnetic fields cause the demagnetization of the magnetic material in the refrigerator main body 1, namely dH is less than 0, dT is less than 0, the adiabatic demagnetization is realized, the temperature of the material is reduced, and heat is absorbed from the outside, so that the refrigeration effect is formed.
