HELICAL COIL TYPE HEAT EXCHANGER AND POWER CONVERSION DEVICE FOR HIGH-TEMPERATURE GAS-COOLED REACTOR

摘要

PROBLEM TO BE SOLVED: To enhance the heat exchange efficiency of an intercooler and make it compact. SOLUTION: Plural heat exchanger tubes 51 are formed in a helical coil 52, and a hollow ring header 53 is installed at the end of the helical coil 52. A coolant 54 introduced from the specified heat exchanger tube 51 is returned at the ring header 53, and reaches an outlet header through the heat exchanger tube 51 forming the helical coil 52. Since the coolant goes to and from the helical coil 52, heat exchange efficiency is enhanced. Attendant on the enhance of heat exchange efficiency, the helical coil 52 can be made compact.
