Abstract: A system and method for deploying a heat harvesting system and for harvesting heat from a geothermal well using one or more heat pipes. A heat exchanger may receive heat from one or more heat pipes for transfer to a heat receiving component. The heat pipes may be thermally coupled to the heat exchanger via a thermal gap material having a relatively low thermal conductivity. A mounting component may engage heat pipes and define a thermal gap between the heat pipes and heat exchanger. A heat spreader, having a relatively high thermal conductivity, may be used to transfer heat from the heat pipes to the thermal gap material and help define a working temperature for the heat pipes. A heat pipe deployment system may include anti-buckling supports and/or a guide to help keep the heat pipes from buckling and to guide the heat pipes into corresponding well bores during deployment.
