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.

A temperature sensor probe is provided with a series of flow channels for deflecting a fluid to be sensed as it flows over the surface of the probe. The flow channels reduce the separation of flow from the surface of the probe thereby increasing the convective heat transfer of the probe and improving the time response of the probe. The temperature sensor probe includes a temperature sensing element housed in a probe housing. In channels are formed on the outer surface of the probe housing. In the preferred form of the invention, the housing is cylindrically shaped and the flow channels extend around the entire circumference of the housing in a spiral fashion so as to form a helical shape extending substantially the entire length of the probe housing.
