Abstract
A heat transfer model of the Annular type downhole heat exchanger (DHE) is presented. Based on his model and the "U" tube type model described by Pan (1983), an optimum design of the DHE using Powell's method is programmed and described in this paper. It is analyzed qualitatively and some parameters of DHE and well affects on the heat output are shown.
