Heat exchange tubing (404) may generally be coupled, or bonded, to header pipe arrangements (302) in order to produce heat exchanging devices which may be used in solar heating systems and thermal energy storage (TES) devices. According to one aspect of the present invention, a method for forming a heat exchanging device includes pretreating the ends of the heat exchange tubes (404) used in the device. The pretreated ends are then heated to at least partially melt the pretreated ends. At the same time, heat is also applied to the header pipe arrangement (302) included in the device to at least partially melt a flange arrangement (306) which is a part of the overall header pipe arrangement (302). The pretreated ends of the heat exchange tubes are then sealed against the header pipe arrangement. |
