Abstract:
A system for cooling an inner vessel that is exposed to high temperatures within its interior, comprising:an outer vessel surrounding said inner vessel;a means for spacing said outer vessel from said inner vessel thereby defining and maintaining a gap intermediate said outer vessel and said inner vessel;a means for pumping a liquid heat removal agent into and out of said gap;a means for enhancing the rate of heat transfer from relatively hotter said inner vessel to relatively cooler said heat removal agent through the creation of turbulent flow in said heat removal agent proximate said inner vessel;said means for enhancing comprising at least one helical bar;each of said at least one helical bar twisted along its longitudinal axis thereby providing it with its helical shape;each of said at least one helical bar attached to said inner vessel within said gap; andwherein, as said heat removal agent flows within said gap, said heat removal agent flows along the length of said at least one helical bar and is induced by said helical shape to flow in a spiral motion thereby creating vortices and turbulent flow proximate said inner vessel.
