摘要:
A passive thermosiphon loop of circulating heat transport liquid transfers heat from an inclined absorber to a heat exchanger in thermal contact with a second fluid. Reverse thermosiphoning under normal conditions is prevented by a ball type check valve. Due to differences in the thermal expansion between the valve ball and the transport liquid, the valve will, however, permit reverse thermosiphoning at high temperatures.
