Russian scientists invented a high-performance magnetic refrigerator

According to the information department of the National University of Science and Technology (NUST MISI) reporting to RIA Novosti, Russian engineers designed a next-generation refrigerator that cooled with magnetic metal. instead of evaporating liquid. This device helps improve energy efficiency by 30-40%.

Researchers from the National University of Science and Technology MISIS (NUST MISI) and Tver State University have invented a new type of refrigerator based on semiconductor magnetic system to improve energy efficiency to 30-40 % compared to gas compressors used in conventional refrigerators. This new design is based on the effect of heat , in which a magnetic field changes the temperature of the magnetic material.

The senior researcher at NUST MISIS, Dmitry Karpenkov, told RIA Novosti that the developers see it as the main achievement of the serial impact in which gadolinium metal bars are placed on a special wheel to put them into a magnetic field by rotating at high velocity.

According to Karpenkov, this is a relatively young technology, only about 20 years old. Even so, Russian researchers are the first to implement the principle of serial. The existing tools are not designed to make the temperature drop sharply and can only maintain a certain temperature.

Researchers have also discussed plans for the future. Developers intend to continue studying the serial principle to expand the temperature range that this refrigerator can reach. Until now, its temperature has changed about 10 degrees, but this range can extend to 12 or 15 degrees.

Karpenkov notes that the edges of the test unit do not exceed 15cm. This small device is believed to be used primarily in car air conditioners and microprocessor cooling systems.
