High-performance multimode elastocaloric cooling system (VIDEO)
Caption
Video showing live operation of a multi-mode elastocaloric cooler (at 10x speed). Superelastic NiTi tube bundles are compressed using hydraulic actuators. In this configuration, there are two top bundles and two bottom bundles operated in concert in direct work recovery mode in order to deliver 150 W of cooling power. The left plot is monitoring the temperature of the cooling medium (water) at outlet points of the bundles (blue: top; red: bottom). The right plot shows the temperatures of the heat source (blue) and the heat sink (red) as a function of time.
