摘要： A flexible, pressurized insert for insertion within the hot (evaporator) side of an inclined heat pipe that forms a part of a heat pipe heat exchanger. This insert is employed in order to prevent such heat pipe from rupturing in the event the working fluid contained therein freezes. This insert is constructed of a thin-walled flexible material that is capable of being deformed (i.e. compressed) thereby absorbing the expansion pressures exerted by the working fluid should the working fluid freeze or be exposed to freezing temperatures. By such absorption, the outer heat pipe itself will not be over-pressurized which might otherwise lead to its rupture. Upon the thawing of the working fluid, the pressurized insert (which is at a pressure greater than that of the working fluid in its non-frozen state) will once again regain its shape.
