Patent ID: 8915058

Claim:
A heat transfer arrangement for a fluid-washed body having first and second ends and a fluid-washed surface extending there-between, said arrangement comprising: a heat transfer member extending from the first end at least part way along the body towards the second end; a heat source arranged in use to heat the heat transfer member in the vicinity of the first end of the body; and, a plurality of thermal control layers on said heat transfer member, each of said layers having a different thermal conductivity and being juxtaposed so as to create a thermal conductivity profile which varies along the length of the member, the plurality of control layers including first and second thermal control layers., wherein the second layer overlays a portion of the first layer such that the first layer covers a greater portion of the heat transfer member than the second layer, wherein the thermal conductivity of said first layer is greater than that of the heat transfer member and the thermal conductivity of said second layer is less than that of the heat transfer member.
