Effect of heat transfer performance of heat pipe on heat rejection efficiency of the miniature heat pipe heat exchanger;

The experimental design and multivariate analysis of heat rejection efficiency of miniature heat pipe heat exchanger

The device absorbing and cooling ammonia was incorporated with U-type heat exchanger,whose upper part is absorbing tower and the lower part is a U-type heat exchanger.

Through measuring the vibration of U-tube heat exchangers in operation and analyzing the vibration of tube bundles, it can be judged the resonance of tube bundles which induced by gas streams and sound waves, is produced while gas flows through shell side and baffle plates.
