1. Pulse electrothermal ice detachment apparatus, comprising:

  • one or more coolant tubes of a refrigeration unit;

    a resistive heater formed from a structure selected from the group consisting of cooling fins in thermal contact with the coolant tubes, and the coolant tubes, the resistive heater comprising a plurality of sections; and

    apparatus for applying electrical power to the resistive heater comprising an intermittent-duty power supply capable of providing at least one kilowatt per square meter of heat exchange surface area of a section of the plurality of sections of the resistive heater;

    wherein the resistive heater is for generating heat to detach ice from at least one of the coolant tubes and the cooling fins;

    wherein the apparatus for applying electrical power comprises a plurality of switches, andthe switches are configured to apply the electrical power to the heater sections individually.
