<p>PCT No. PCT/SE85/00341 Sec. 371 Date May 8, 1986 Sec. 102(e) Date May 8, 1986 PCT Filed Sep. 11, 1985 PCT Pub. No. WO86/01837 PCT Pub. Date Mar. 27, 1986.This invention relates to anodic corrosion protection for heat exchangers and comprises cathodes put into the inlet channel and the outlet channel for the corrosive medium and an anode constituted by the metal being the partition walls in the heat exchanger. The anode and the cathodes are integral parts of a direct current circuit, the amperage of which is influenced by a control reference electrode placed in the flow way for the corrosive medium. The characterizing feature of the invention is that the control reference electrode (11) is arranged in the ordinary or a separate flow way for the corrosive medium at an essential distance from the cathodes (9, 10) so that the corrosion protection of all parts of the heat exchanger, which are to be protected, is secured.</p> |
