Patent ID: 7703503

Claim:
A method for fabricating a heat pipe heat exchanger, comprising the steps of: providing a heat pipe containing a predetermined amount of hydraulic fluid; providing a heat conductive member having a heat pipe-holding hole with a cross section other than a perfect circle prior to a heat treatment; installing the heat pipe in the heat pipe-holding hole to provide a gap between the heat pipe and the heat conductive member prior to a heating treatment such that at least one part of the heat pipe is surrounded at all sides by said heat conductive member; and embedding the heat pipe in the heat pipe-holding hole, the embedding of the heat pipe comprising plastically deforming the heat pipe in the heat pipe-holding hole by heating tube expansion such that the heat pipe is fixed to the heat conductive member, the plastically deforming of the heat pipe comprising heating the heat pipe at a predetermined temperature such that an outer periphery surface of the heat pipe is in contact with an inner periphery surface of the heat conductive member while keeping spaces between the outer periphery surface of the heat pipe and the inner periphery surface of the heat conductive member, after expansion of the heat pipe, positioning the heat conducting member to receive heat from a heat exchange object.
