PURPOSE: To provide the title element with a resistance to corrosion, facilitate to enlarge the size thereof and increase the heat transfer area per unit volume thereof by a method wherein a plurality of tubes, made of glass, is arranged in parallel substantially, connecting between tubes is effected by a resin form and gaps, through which liquid passes, are provided between tubes.
CONSTITUTION: In the heat accumulating element 11, multiple glass tubes 12 are arranged in parallel substantially and both ends thereof are retained by retainers 13 while the glass tubes are attached to a section surrounded by an inner ring 19, an outer ring 20 and supporting members 21 connecting the inner ring 19 to the outer ring 20. Gas to be heated and heating gas are made to flow through the inside and outside of the tubes 12 utilizing the inner and outer peripheral walls of the tubes 12 as the heat transfer surface and the tubes are long in the flow direction of the gas, therefore, large heat transfer area may be obtained, heat retrieving efficiency may be improved and the pressure loss of the gas may be reduced. Further, stress and mechanical shock, which are caused by thermal expansion, are absorbed by the retainers 13, therefore, breakage of the glass tubes may be prevented. Furthermore, the tubes 12 are made of glass and the retainers 13 are made of fluorine resin, therefore, anticorrosion may be obtained.
