CONTINUOUS TYPE FLUID TEMPERATURE-RETAINING CONTAINER

摘要

PROBLEM TO BE SOLVED: To obtain a continuous type fluid retaining container capable of preparing a flow path having prescribed length so as to be low in height and simply and inexpensively carrying out heat-retaining engineering work and installation work by spirally rolling two sheets of metal plates and forming continuous flow path in one container. SOLUTION: This continuous type fluid temperature-retaining container comprises a bulkhead plating 1, two sheet of spiral plates 2 and 3 connectedly installing the ends of the internal circumference at both ends of the bulkhead plating 1 and two flange plates 7 and 8. Spiral flow paths R1 and R2 which are each independent are formed by spirally rolling both spiral plates 2 and 3 and the space between both flow paths is made to conduct in outer peripheral end parts of these both flow paths R1 and R2.
