Abstract

A thermal pump may include a cylinder having a hot end and a cold end, with heating elements at the hot end and cooling elements at the cold end. A piston assembly movable within the cylinder may include a regenerator, a hot displacer, and a cold displacer. The hot displacer can include a thermally-conductive segment shaped to surround the heating elements when in a cooling position, and a thermally-insulating segment between the conductive segment and the regenerator. The cold displacer can include a thermally-conductive segment shaped to surround the cooling elements when in a heating position, and a thermally-insulating segment between the conductive segment and the regenerator.
