Abstract
A cooling system includes an electrocaloric element (12) having a liquid crystal elastomer or a liquid form liquid crystal retained in an elastomeric polymer matrix. A pair of electrodes (14.16) is disposed on opposite surfaces of the electrocaloric element. A first thermal flow path (18) is disposed between the electrocaloric element and a heat sink (17). A second thermal flow path (22) is disposed between the electrocaloric element and a heat source (20). The system also includes a controller (24) configured to control electrical current to the electrodes and to selectively direct transfer of heat energy from the electrocaloric element to the heat sink along the first thermal flow path or from the heat source to the electrocaloric element along the second thermal flow path.
