Heat retaining device of heat retaining device line U letter die structure of cylindrical drum or tank and cylindrical steel

摘要

(57) Abstract (Modified) Topic With former heat retaining device inishiyarukosuto or runThere to be a problem as for ningukosuto and the like as an energy-saving structure, in applicationResponding there to be also a structure which it cannot be adapted, still being able to solveIt is. SolutionsThe surface or surface condition heating element 3 which has flexibility, furthermore the surfaceControl heating element 3 is designated as power source, the high temperature effect is brought in low temperatureYou are confined as a configuration and provide thermal layer 4. As for confined heat from belt surfaceOne is effective, with respect to energy-saving structure, it fits to orbicular structure,The te can be interposed with the flexibility which, surface heating element utilization the thermal returnEfficiency is high.
