ELASTOCALORIC HEAT PUMP AND MOTOR VEHICLE COMPRISING ELASTOCALORIC HEAT PUMP

An elastocaloric heat pump including at least one first cooling medium channel, at least one second cooling medium channel, at least one elastocaloric element, and a drive device. The elastocaloric element is positioned between the first and second cooling medium channels and connected at each end to a carriage. The carriages are displaceably arranged on two guide means that are not parallel to each other. The drive device is configured to cyclically displace the carriages along the guide means, thereby alternately bringing the elastocaloric element into thermal contact with an outer wall of the first cooling medium channel and an outer wall of the second cooling medium channel. This configuration satisfies high leak tightness requirements and achieves high efficiency.
