Machine Details
Description
It is a demonstration device to show the magnetic cooling to interested people. The system consists of a Halbach magnet arrangement with a flux density of up to 1.5 T, which is in a fixed position. The magnetocaloric material is moved in and out the magnet linearly by manually operating a crank wheel. The transmission allows for frequencies up to 3 Hz. Furthermore, a piston pump, also driven via the shaft generates an oscillating fluid. The heat generator consists of a housing with a sample of gadolinium spheres and temperature sensors. A microcontroller
measures the temperature and plots the data on a touch display To be used under the supervision of trained operators for demonstration purposes. Not CE, EMC or ATEX certified.
