Abstract
An elastocaloric heat pump requiring little installation space wherein the elastocaloric heat pump includes an elastocaloric element, a first coolant duct and a second coolant duct and at least one drive device, wherein the elastocaloric element is connected to a carriage on the end sides in each case, the carriages are arranged displaceably on two guide mechanisms which are not parallel to each other, and the drive device cyclically displaces the carriages along the guide mechanism so the elastocaloric element is displaced cyclically and cyclically expanded between the first coolant duct and the second coolant duct.
Claims7
An elastocaloric heat pump comprising:
- a first coolant duct;
- a second coolant duct;
- an elastocaloric element connected on each end side to a respective carriage, wherein the carriages are arranged displaceably on two guide mechanisms, which are not parallel to each other;
- and
- at least one drive device that cyclically displaces the two guide mechanisms that correspond to the carriages so the elastocaloric element is displaced cyclically and cyclically expanded between the first coolant duct and the second coolant duct.
