<p>PROBLEM TO BE SOLVED: To reduce heat losses during the transportation of a heat medium by arranging a conductive wire between a plurality of heat medium flow passages so as to keep distances between the plurality of heat medium flow passages and covering the entire parts of the plurality heat medium flow passages and the conductive wire with a heat insulating covering material. SOLUTION: First and second cables 3 and 4 are arranged between first and second heat medium flow passages 1 and 2 and the first and second heat medium flow passages 1 and 2 are placed away from each other. The first and second heat medium flow passages 1 and 2 and the first and second cables 3 and 4 are integrally covered with a heat insulating covering material 5. Thus, heat transmission between the heat medium flow passages is almost surely shut off. Further, since the outer peripheral parts of the heat medium flow passages are covered with the heat insulating covering material, heat radiation to the outside of the heat medium flow passages is reduced.</p> |
