摘要： A heat exchanger (102) for exchanging heat between gasses such as air and a liquid or gaseous coolant has narrow spacing (108) between exchanger surfaces for high efficiency. To avoid undue obstruction of gas flow due to ice buildup on the exchanger surfaces,- the heat exchanger (102) is equipped with sensors (110, 112) to monitor the gas flow and an actuator (116, 118) that widens the spacing (108) between exchanger surfaces such that gas flow remains unimpeded. Embodiments provide for defrosting of the exchanger surfaces when an limit on spacing (108) of exchanger surfaces is reached, and for relaxing the spacing (108) to the original narrow spacing (108) when defrosting is completed.

摘要： Systems and methods for pulse electrothermal and heat-storage ice detachment. A pulse electrothermal ice detachment apparatus includes one or more coolant tubes (4) , and optionally, fins (2) in thermal contact with the coolant tubes. The tubes and/or fins form a resistive heater (10) . One or more switches (12) may apply electrical power to the resistive heater, generating heat to detach ice from the tubes and/or the fins. A freezer unit (400) forms a heat-storage icemaking system having a compressor (410) and a condenser (420) for dissipating waste heat, and coolant that circulates through the compressor, the condenser and a coolant tube (430) . The coolant tube is in thermal contact with an evaporator plate (435) . A tank (440), after the compressor and before the condenser, transfers heat from the coolant to a heating liquid (445) . The heating liquid periodically flows through a heating tube in thermal contact with the evaporator plate, detaching ice from the evaporator plate.

摘要： A pulse system for detaching ice includes a power supply for applying a high-power heating pulse to the interface between ice and an object such as a cold plate of an ice making system, an ice-container, a heat-exchanger, a refrigerator surface or an airplane wing. Pulse heating may be generated within a metal foil or resistive film disposed upon an object to be deiced, or a capillary tube 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.

A controller is capable of detecting ice accumulation and connecting the tubes to a source of electrical power for deicing when it is necessary to deice the tubes. Embodiments having a manifold having multiple conductive sections insulated from each other are disclosed for coupling tubes electrically in series. Alternative embodiments with a single, long, wide-bore, tube are disclosed, as are embodiments having an evaporating pan coupled in series or parallel with the tubes, and embodiments with thermal cutoff and electrical safety interlocks.

A method of optimizing thicknesses of complex shapes for a pulse electrothermal deicing system includes assigning initial estimates of the pulse electrothermal deicing system parameters. A temperature distribution, a temperature range and a refreezing time produced by a deicing pulse are modeled. Shape thicknesses are adjusted according to the temperature range, deicing pulse parameters are adjusted according to the deicing pulse, and the modeling and adjusting is repeated until the temperature range and the refreezing time are within predetermined limits.
