GLAS-METALL-VERBINDUNG INSBESONDERE FÜR EINEN VAKUUM-ROHR-SOLARKOLLEKTOR |
摘要 |
The invention relates to a glass-metal connection, in particular for a vacuum-tube solar collector, comprising a metallic connecting part (1), which connects a heat recovery tube (3) and a enclosing tube (2) of glass in a vacuum-tight manner, one end (5) of the enclosing tube (2) being inwardly deformed in a flange-like manner in such a way that it encloses an outer edge portion (7) of the metallic connecting part (1) in a vacuum-tight manner on both sides by fusing. This edge portion (7) is expediently formed in a rotationally symmetrical manner and/or the enclosing tube (2) is produced from a soda-lime glass. The connecting part (1) is connected in a vacuum-tight manner to one or more heat recovery tubes (3). The connecting part (1) and the glass of the enclosing tube (2) have approximately the same coefficient of expansion. |
