摘要： Disclosed is a heat transfer system with a module that includes a peripheral frame (10) and an electrocaloric element (46) disposed in an opening in the peripheral frame. The electrocaloric element includes an electrocaloric film (46), a first electrode (48) on a first side of the electrocaloric film, and a second electrode (50) on a second side of the electrocaloric film. First and second electrically conductive elements (24, 25) are disposed adjacent to first and second surfaces of the peripheral frame, and provide an electrical connection to the first and second electrodes.

摘要： A heat transfer system includes first (62) and second (64) electrocaloric module with aligned first and second sides. First and second prime movers (80,82) are arranged to direct a working fluid in opposite directions along flow paths through the electrocaloric modules. A rotary fluid control device (92,98) including a plurality of openings (94,96,100,102) is disposed around the electrocaloric modules, and is configured to rotate between positions relative to the modules. In a first position, the first module is in operative fluid communication through the openings with the first prime mover, and the second module is in operative fluid communication through the openings with the second prime mover. In a second position, the first module is in operative fluid communication through the openings with the second prime mover, and the second module is in operative fluid communication through the openings with the first prime mover.

摘要： A cooling system includes an electrocaloric element having a nanoparticulate ion scavenger and a co-continuous polymer network of a first polymer phase and a second polymer phase wherein the first polymer includes a liquid crystal polymer. A pair of electrodes is disposed on opposite surfaces of the electrocaloric element. A first thermal flow path is disposed between the electrocaloric element and a heat sink. A second thermal flow path is disposed between the electrocaloric element and a heat source. The system also includes a controller 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.
