<p>PROBLEM TO BE SOLVED: To achieve a heat exchange part capable of maintaining heat exchange efficiency at a high level while eliminating troublesome processing and refrigerant leakage in an ice plant.SOLUTION: In the ice plant comprising: a heat exchange region 18 where heat exchanges with brine; an ice making vessel for ice making by immersing an ice making can filled with fresh water into brine in the heat exchange region 18 where brine circulation is formed; and a heat exchange part 18a for cooling brine, the heat exchange part 18a includes a plurality of linear refrigerant pipes 44 arranged in a flow direction of brine as well as slanting to a vertical direction with respect to a horizontal plane, and header pipes 60 and 62 connected to the plurality of linear refrigerant pipes in a pipe axial direction keeping intervals. Both ends of the linear refrigerant pipes 44 are connected to the header pipes in a state of orthogonally crossing the header pipes, so that a refrigerant supply pipe 40a and a refrigerant return pipe 40b are connected to the header pipes 60 and 62, specifically, the refrigerant supply pipe 40a is connected to a lower portion of the header pipes 60 and 62 and a refrigerant gas return pipe 40b is connected to an upper portion of the header pipes 60 and 62.</p> |
