A deicing apparatus includes a heat source for producing deicing heat at one location on the body of an object and a heat distributing arrangement for distributing the deicing heat to one or more surface areas to be deiced. The heat distributing arrangement comprises thin strips or channels of heat distributing material having a heat conductivity greater than that of the material from which the remainder of the object is formed. One end or a portion of each strip or channel of the heat distributing material is in contact with the heat source itself or in contact with a highly heat conductive potting material in which the heat source is set. Another portion of each strip or channel of heat distributing material preferably forms a portion of one of the surface areas to be deicd. The heat distributing arrangement conducts heat from the remote heat source to each surface to be deiced through the highly heat conductive heat distributing material alone and without having to extend a heating element across each separate surface to be deiced.

An aerodynamic component adapted to operate in icing conditions comprising: (a) a component body having a leading edge, said component body including a plurality of channels, each channel extending from the heat source cavity to a different deicing area on the component body and across the surface of the component body in the respective deicing area; (b) a heat source capable of supplying deicing heat, the heat source being mounted within the component body in a heat source cavity beneath a first surface area of the body; and (c) heat distributing means in contact with the heat source and extending away from the first surface area of the body to a deicing area on the outer surface of the body where deicing is desired and forming a portion of the outer surface of the component in the deicing area, the heat distributing means for conducting the deicing heat supplied by the heat source to the deicing area and comprising a heat distributing material which includes a channel material positioned in the channel, said heat distributing material having a heat conductivity greater than that of the material from which the remainder of the component body outer surface is formed.
