Abstract : An analytical study was conducted to determine the practicality of using a buried closed-loop, small-diameter coiled-pipe heat sink instead of a reservoir-type sink for emergency disposal of waste heat. The analysis was broadly based to permit application to a variety of soil types, mean ground temperatures, heat rejection rates, coolant water flow rates, pipe sizes, coil surface areas and coil spacings. The intent of the study was to present a problem-solving technique that would be useful to a design engineer faced with considering the use of a buried coiled pipe to dissipate a rather large amount of heat to the ground during a very limited period. The feasibility of such a system was found to be highly dependent upon the length of pipe required and the installation layout requirements for such a pipe network. (Author)
