<p>A pulse system for detaching ice includes a power supply (22) for applying a high-power heating pulse to the interface between ice and an object such as a cold plate (12(2)) of an ice making system, an ice-container (102(2)), a heat-exchanger (40), a refrigerator surface or an airplane wing (122). Pulse heating may be generated within a metal foil (18(1)) or resistive film disposed upon an object to be deiced, or a capillary tube (104(4)) proximate the object to be deiced. An interfacial layer of ice is melted and the ice is released from the object. A force, for example gravity, pressure of vaporization or mechanical scraping, removes the ice from the object.</p> |
