PROBLEM TO BE SOLVED: To efficiently aggregate and line up heat storage material units in a heat storage tank used for an LNG cold energy system. SOLUTION: The system consists of a vertical supply pipe 11 for flowing down low temperature liquid, a branch line network 12 which is connected to the lower end of the pipe 11, a heat exchange piping group 13 which communicates with the network 12 and in which a plurality of the pipes are set up parallel to the pipe 11 from the pipe surface so as to have substantially the same height therewith for flowing up the low temperature liquid, a header 14 wherein the upper end of the piping group 13 is connected to individual portions for collection of the low temperature liquid, and a return pipe 15 which is connected to the header 14. The system except its upper part is embedded in a curing thermal storage material unit 10 of substantially narrow and long rectangular shape.
