And permanent magnet is made to separate, contact with magnetic work package, to change the magnetic field for being applied to magnetic operation material.At this point, if making application
Magnetic field increases (excitation), then the temperature of magnetic operation material rises, if the magnetic field applied is made to reduce (demagnetization), magnetic operation material
Temperature decline.
On the other hand, using displacer (piston) or the thermal medium mobile device being made of pump and rotary valve etc., make heat
Medium (water etc.) moves back and forth between the temperature end and low-temperature end of magnetic work package.In this case, to magnetic operation material into
Row excitation rises its temperature, moves thermal medium to high temperature end side from low-temperature end side, so that temperature be made to rise because of excitation
The thermal medium heat exchange of magnetic operation material and low temperature.Magnetic work package generates the temperature that high temperature end side is high and low temperature end side is low as a result,
Gradient.
Then, if carrying out demagnetization to magnetic operation material, temperature decline makes thermal medium be moved to low-temperature end from temperature end side
Side, thus the thermal medium heat exchange for the magnetic operation material and high temperature for declining temperature because of demagnetization.The temperature of magnetic work package as a result,
Gradient further expansion.
So, by the temperature change accumulation of heat that will be generated by magnetothermal effect in magnetic work package itself, and low temperature is utilized
The thermal medium of end side and high temperature end side is efficiently expelled to outside, thus using external heat exchanger absorbed heat (refrigeration) or
It radiates (heating).

On the other hand, in the present invention, demagnetization (reducing magnetic field) is carried out in the magnetic operation material 13 to magnetic work package 11A
Later, it acts displacer 8 and is to continue with the heat exchange of thermal medium Yu magnetic operation material 13.Shown in Fig. 5
Dotted line L4 be thermal medium in this case temperature, dotted line L5 is thermal medium when making thermal medium mobile while demagnetization
Temperature.The temperature of dotted line L4 is lower than the temperature of dotted line L5.
Then, as shown in fig. 6, by displacer 8, make thermal medium from 14 side of temperature end of magnetic work package 11A towards low temperature
Hold 16 sides mobile.In this case, in embodiment, permanent magnet 6 (is made into application to the progress demagnetization of magnetic operation material 13
The size in magnetic field reduces) time be set as T2 in the case where, carrying out demagnetization to magnetic operation material 13 in permanent magnet 6 (makes to apply
The size in magnetic field reduces) after 0.25 × T2 or more, 0.33 × T2 time below after, by displacer 8, make thermal medium
It is mobile from 14 side of temperature end of magnetic work package 11A towards 16 side of low-temperature end.In addition, the L6 in figure is magnetic operation material 13 at this time
Temperature.
As described above, in the present invention, the size in the magnetic field for making permanent magnet 6 be applied to magnetic operation material 13 increase (into
Row excitation) before, by displacer 8, make thermal medium from 16 side of low-temperature end of magnetic work package 11A, 11B towards 14 sidesway of temperature end
It is dynamic, therefore, the thermal medium of low temperature can be sent into magnetic working substance before the size for being applied to the magnetic field of magnetic operation material 13 increases
Matter 13 can make the temperature difference of the magnetic operation material 13 risen because magnetic field later increases become larger.
Thereby, it is possible to make magnetic operation material 13 and thermal medium efficiently carry out heat exchange, expand magnetic work package 11A, 11B
Temperature gradient between temperature end 14 and low-temperature end 16, to efficiently and effectively utilize by the magnetothermal effect of magnetic operation material 13
The temperature change of generation.
In this case, in embodiment, increase in the size that permanent magnet 6 is made to the magnetic field for being applied to magnetic operation material 13
In the case that the big time is set as T1, starting to increase the 0 of the size in the magnetic field for being applied to magnetic operation material 13 than permanent magnet 6
Greatly, before 0.15 × T1 time below, by displacer 8, make low-temperature end 16 side court of the thermal medium from magnetic work package 11A, 11B
14 side of temperature end is mobile, and therefore, the temperature that can effectively utilize magnetic operation material 13 rises.
In addition, by displacer 8, making after the size in the magnetic field for making permanent magnet 6 be applied to magnetic operation material 13 reduces
Thermal medium is mobile from 14 side of temperature end of magnetic work package 11A, 11B towards 16 side of low-temperature end, therefore, can be applied to magnetic working substance
The size in the magnetic field of matter 13 makes thermal medium mobile after reducing, and the magnetic operation material that can be declined using temperature because magnetic field reduces
13, decline the temperature of thermal medium further.
Thereby, it is possible to effectively utilize the decline of the temperature of magnetic operation material 13, expand the temperature end of magnetic work package 11A, 11B
Temperature gradient between 14 and low-temperature end 16, to efficiently and effectively utilize by the magnetothermal effect generation of magnetic operation material 13
Temperature change.
In this case, in embodiment, subtract the size in the magnetic field for being applied to magnetic operation material 13 permanent magnet 6
In the case that the small time is set as T2, after permanent magnet 6 reduces the size for being applied to the magnetic field of magnetic operation material 13
After 0.25 × T2 or more, 0.33 × T2 time below, by displacer 8, make thermal medium from the height of magnetic work package 11A, 11B
Warm 14 side of end is mobile towards 16 side of low-temperature end, therefore, can effectively utilize the temperature decline of magnetic operation material 13.
In addition, in embodiment, implement makes thermal medium from 16 side of low-temperature end before carrying out excitation to magnetic operation material 13
Make thermal medium from 14 side of temperature end towards low temperature towards the mobile control in 14 side of temperature end and after carrying out demagnetization to magnetic operation material 13
The control for holding 16 sides mobile, however, it is not limited to this, and it is also effective for only implementing any control.
In addition, the overall structure of magnetic heat pump assembly is also not limited to embodiment, thermal medium mobile device can also be by recycling
Pump and rotary valve are constituted, to replace displacer 8.
