When stacking two or more layers of spiral tubes as a paraffin-impregnated layer, the heat storage tube can be bent by winding the paper tube in a spiral shape while gradually shifting the winding end faces in the same direction. Furthermore, if the helical direction is reversed, the strength of the paper tube increases.
