For orderly ferromagnetic phase and therefore lead to magnetic phase transition, the induction which can also be described as the Curie temperature of material is increased to
On environment temperature.This magnetic phase transition means magnetic entropy Δ SmagReduction and close to adiabatic process (heat with environment temperature
Insulation) caused by phonon generation magnetocaloric material lattice entropy contribution increase to save entropy under adiabatic conditions.
Due to applying external magnetic field, the heating (Δ T) of magnetocaloric material occurs.
In the cooling application of technology, this additional heat is removed and the heat transfer to environment heat sink from material.Heat is logical
It crosses heat transfer medium and is transported to environment heat sink from material.Water is the example for the heat transfer medium from magnetocaloric material removal heat.
For being lower than 0 DEG C of temperature, antifreeze additive, such as ethylene or propylene glycol, ethyl alcohol or salt can be added into water.
Then, remove external magnetic field can be described as Curie temperature fall back to magnetocaloric material initial temperature it
Under, and therefore magnetic moment is allowed to revert to random arrangement.In the condition for being almost insulated --- being thermally isolated with environment temperature ---
Go down to remove external magnetic field, it means that the total entropy in system remains unchanged.Since magnetic entropy increases in the case where no external magnetic field
Its base level is added to, the entropy of the lattice of magnetocaloric material itself, which is contributed, to be reduced, and therefore under the conditions of almost adiabatic process
Magnetocaloric material is caused to be cooled under initial temperature.
In equipment applications, described includes magnetizing typically periodically to carry out with the process of demagnetization circulation.
2012/0031107 A1 of document US describes a kind of heater, has at least one thermal modules, the hot-die
Block includes at least two mangneto thermal elements.The heater is characterized in that it includes at least two magnet assemblies, one of them
Magnet assembly makes at least one mangneto thermal element of thermal modules be subjected to alternate magnetic phase.The heater is further characterized in that it is wrapped
Heat insulator is included, which keeps magnet assembly insulated from each other and formed to include a magnet assembly and its corresponding mangneto
The thermal isolation cell of thermal element.
Summary of the invention
The design of the prior art can be modified.It is an object of the invention to create a kind of improved mangneto thermal.Tool
For body, it is an object of the present invention to reduce the temperature difference between the environment of magnetocaloric material and magnetocaloric material itself to be led
The heat leak of cause.
According to the present invention, the purpose is realized using mangneto thermal as defined in claim 1.
The present invention provides a kind of mangneto thermals, especially mangneto heat driven heat pump comprising：

Mangneto thermal according to the present invention is provided with exhausted advantageously around the mangneto thermal element comprising magnetocaloric material
Edge device.Particularly, the thermal conductivity between mangneto thermal element and magnet assembly and/or ambient enviroment with there is no around mangneto heat
The mangneto thermal of the seal of element is compared to reduction.
By providing reduced thermal conductivity, mangneto thermal according to the present invention realize reduced heat leak amount and because
This can pump more heat for given input work, this improves the efficiency of mangneto thermal.In addition to low heat conductivity it
Outside, the low heat transfer of the component of mangneto thermal can advantageously reduce the overall heat-transfer coefficient of mangneto thermal.Particularly, it insulate
Device can prevent or reduce water condensation, freeze or being thermally connected by ambient enviroment into the heat transfer or system of ambient enviroment
The component under the different temperatures between heat transfer.The heat transfer coefficient of free convection is usually less than 10W/m2/K.Conversely, because
Heat transfer caused by condensation typically results in heat transfer coefficient greater than 100000W/m2/ K, and by the compulsory convection current of rotating magnetic field generator
Heat transfer coefficient be can lead to greater than 100W/m2/K.It is thus particularly advantageous to provide a kind of magnetic thermal device, wherein seal can
To reduce due to condensation and/or conduct heat as caused by the compulsory convection current of rotating magnetic field generator.
According to the heating of the magnetocaloric material during the magnetization and demagnetization phase triggered by periodically variable external magnetic field
