HEAT MEDIUM DISTRIBUTOR FOR ANNULAR DUCT OF REACTOR AND HEAT EXCHANGER

摘要

An annular duct and a heat exchanger comprising the same are provided to prevent internal disturbance due to flowing of fluid within the heat exchanger, by dividing or collecting the fluid at the uniform amount rate using a guide plate when the fluid flows into or flows out of the duct. An annular shaped slit layer(9) is formed on an inner circumference of an annular duct(5a), wherein the slit layer has one or more slits for inflow or outflow of fluid. A guide plate(11) is perpendicularly installed within the duct in an extension direction of a diameter defined by the inner circumference of the duct. The guide plate divides the fluid inputted through the duct at the uniform amount rate, and collects the fluid outputted through the duct at the uniform amount rate.
