Abstract

A thermosyphon heat exchanger having evaporator and condenser sections is provided which includes an internal bladder capable of defining an internal volume which is substantially equivalent to the internal volume of the thermosyphon, the bladder containing working fluid which acts to transfer heat being delivered to the evaporator section of the thermosyphon to the condenser section of the thermosyphon. The thermosyphon provided, including the internal bladder, is more easily constructed than known thermosyphons due the ease of pressure relief and there being no requirement of extreme cleanliness within the thermosyphon. Also provided is a method of constructing a thermosyphon in accordance with present thermosyphon.
