Magnetocaloric effect and magnetic cooling method

Magnetocaloric effect and magnetic cooling method.

 

 

The magnetocaloric effect is the reversible temperature change of a magnetic substance (magnetic substance) in its adiabatic magnetization (or demagnetization).

 


Description:

The magnetocaloric effect is the reversible temperature change of a magnetic substance (magnetic substance) in its adiabatic magnetization (or demagnetization).

The magnetocaloric effect is such a chemical elementas gadolinium. It is as follows: if to the gadolinium to bring the magnet, it will heat up, and if removed, then it cools down. This property makes the installation in the form of a wheelcontaining gadolinium crushed. The wheel rotates near a permanent magnet. When approaching the magnet, the gadolinium heats up. From gadolinium through the heat exchanger with water or other working fluid is drawn off the heat. Then gadolinium when removed from the magnetic field cools and takes heat to another closed system through a heat exchanger, which circulates water or other working fluid.

It is established that gadolinium discovers the largest magnetocaloric effect. Magnetocaloric effect in other materials, e.g., NdFeB.

Based on the magnetocaloric effect created by the magnetic refrigerator.
