Summary

A new heat transporter is described, the tiltpipe liquid thermosiphon (TLT). In service, a straight, sealed pipe, filled with liquid, is maintained in a tilted orientation. By means of the contained liquid, heat is received from a heat source at the lower end of the pipe, transported to the elevated end, and delivered to a heat sink. The heat transport rate and the temperature distribution in the TLT were studied over a wide range of tilts, with water as the liquid, contained in a steel pipe. At its optimum tilt the TLT combined a high heat transport rate with virtually no temperature degradation in the water from end-to-end of the pipe. In both of these criteria the TLT far exceeded the performance of the unit in vertical orientation, the only one examined by previous investigators. Differences in the behaviour of vertical and tilted pipes are explored and explained.
