Background technology
Magnetic thermal effect (EMC) of the magnetic refrigeration technique based on some materials, it is included in magneto-caloric material and is subjected to magnetic hot material during magnetic field
The temperature change of material.As long as these magneto-caloric materials is subjected to a series of magnetization and demagnetization circulations and utilize heat transport fluid real
Applying heat change can with the temperature change for reaching maximum possible.Passed as an example, the efficiency of this magnetic refrigeration cycle exceedes
The efficiency of controlling SAPMAC method about 30%, this causes this technology to be particularly conducive to room air adjusting or refrigeration application.However,
This technology can be applied to very more hot fields, and such as heating, temperature adjustment, freeze, refrigeration.
When the temperature of material is close to its Curie temperature, magnetic thermal effect (EMC) is the largest, and Curie temperature (Tc) is material
Lose temperature during its spontaneous manetization.Above this temperature, material is in the irregular state of so-called paramagnetic.
Some magnetic materials such as gadolinium, lanthanum or some manganese-iron (MnFe) type alloys have the magnetic heat particularly suitable for aforementioned applications
Performance.In these alloys, the alloy of silicon (Si) base is particularly, it is known that lanthanum-iron-silicon-cobalt is used according to the Curie temperature sought
The alloy of LaFeSiCo bases or with hydrogen lanthanum-iron-silicon-cobalt LaFeSi (H) base alloy, in these alloys by light atom such as
It is that the EMC effects of material are maintained at by a kind of increase and/or adaptation Curie temperature at the same time in hydrogen or cobalt Insertion compound LaFeSi
High-caliber effective ways.These materials are especially interesting, because the manufacture cost of their magnetic heating performance combination reduction,
Allow to utilize the material cost obtained for such as gadolinium of material known to its natural magnetic thermal effect and environmentally friendly influence aspect more favourable
Widely apply on ground.
Typically for the hot property of utilization magneto-caloric material, magnetic refrigeration technique is based on utilizing heat transport fluid these materials
