    Abstract: PURPOSE:To prevent cooling pipes from being corroded due to dew condensation on them by improving the heat conduction between the outer casing and the pipes in the inner casing zone by using a thermally conductive and corrosion-resistant hot melt for fastening the plastic inner casing and the cooling pipes, for treating the cooling pipes for corrosion resistance, and for fastening the outer casing and the heat radiating pipes. CONSTITUTION:The cooling pipes 5 are temporarily set just off of the inner casing 3 and the heat radiation pipes 6 just off of the outer casing 2 similarly, and then, the thermally conductive and corrosion-resistant hot melt 8 is applied to them for bonding. The hot melt 8 contains carbon powder 10 and metallic oxide powder in the base of atactic polypropylene 9. Because the metallic oxide 11 has a greater specific gravity, the thermally conductive and corrosion-resistant metallic oxide powder 11 and the corrosion-resistant atactic polypropylene 9 get between the inner casing 3 and the cooling pipes 5, and between the outer casing and the heat radiation pipes 6. The inner casing 3 is set inside the outer casing 2 with the closed space 13 filled with a heat insulating material 4. As the heat insulating material 4 does not enter between the inner casing 3 and the cooling pipes 5 and between the outer casing 2 and the heat radiation pipes 6, the heat exchange takes place efficiently, and, because the cooling pipes 5 are covered with the hot melt 8, they are prevented from being corroded due to condensation thereon.
