Abstract
In an internally cooled tubular ozonizer, there is built into the interior of the glass tube (5) a cooling tube (9) whose outer diameter is only slightly smaller than the inner diameter of the glass tube (5). The annular gap left is filled up with a temperature-resistant casting compound (10) which conducts heat well. In the case of a synthetic resin casting compound (10), the cooling tube (9) is connected galvanically via contact springs (11) to the metal layer (8), serving as the inner electrode, on the inner wall of the glass tube (5). The heat transfer from the cooling agent in the cooling tube (8) to the glass tube (5) is not impeded by the casting compound (10). Temperature stresses between the glass tube (5) and the cooling tube (9) are largely reduced, as a result of which the operational safety of the ozonizer is increased, especially at fairly high power densities.
