Rare earth magnetic refrigeration device into practical

Reporters learned from the Baotou Rare Earth Research Institute , refrigerator magnet hospital research project is progressing well , has completed two sets of magnetic refrigeration device and subsequent design study , the first three magnetic refrigeration device is currently being manufactured .

Magnetic refrigeration is using the principle of magnetocaloric effect has performed magnetic refrigeration . According to Huang , deputy chief engineer of rare earth homes macro focus introduced in 2012, Haier Group set up a dedicated R & D team in the research and application of magnetic refrigeration research and development prospects at home and abroad , in March 2013 in cooperation with the Baotou Rare Earth Research Institute to develop practical magnetic refrigerator and invested 5 million yuan joint design and development of magnetic refrigerators . Current research of rare earth magnetic refrigeration hospital is practical , consider using a performance guarantee from both the cost and price , each magnetic refrigerator consumes 2-5 kg ​​NdFeB, but only at the cost of less than 1,000 yuan NdFeB , refrigerator final price of 3,000 yuan , the product to get market recognition.

It is understood that China's current annual output of air conditioners, refrigerators approximately 100 million units, even if the initial magnetic refrigerator running only 1% of the market share , the annual output can reach 100 million units , the estimated annual consumption of 2,000 tons to 5,000 NdFeB ton, plus the demands of foreign markets , mass production of magnetic refrigerator demand for NdFeB magnets will be very considerable. Currently, developed countries are actively researching magnetic refrigerator .
