SELF-REGULATING HEAT PIPE Russian patent published in 2011 - IPC F28D15/06 

FIELD: heating.

SUBSTANCE: device consists of heat pipe (HP) and thermal regulating unit containing three bellows: with non-condensing gas ("gas bellow"), "condensate" bellow exchanging the condensate with HP and "independent" bellow filled with specially chosen fluid and sealed. Bellows form power-reservoir system: "heat pipe - condensate bellow - independent bellow". When heating (cooling) the stabilised object, independent bellow is deformed, thus influencing two other ones. As a result of mechanical action some portion of gas fills in HP condenser, thus partially displacing from it the working medium to condensate bellow, which reduces effective conductivity of HP. During the cooling process, action of bellows has inverse sequence. Independent bellow is filled with fluid the inclination angle of steam saturation curve of which to temperature axis exceeds similar value in fluid in HP.

EFFECT: regulation after itself without special energy sources and additional devices of electric or other nature.
