<p><P>PROBLEM TO BE SOLVED: To provide a plate type heat exchanger in which, even when set to a seawater cooling water system, marine deposition organisms, and fouls such as slime and scale are prevented from be stuck to the surface of the heat exchanger, and which secures space-saving and further can maintain heat exchangeability over a long period, and to provide an antifouling device therefor. <P>SOLUTION: In the plate type heat exchanger, insulation treatment is performed so as to prevent the short-circuit of the contact part in each heat-transfer plate. In the antifouling device for the plate type heat exchanger, a power source of applying direct electric current with the heat-transfer plates in the plate type heat exchanger as electrodes is provided, and the anode plates and the cathode plates are alternatively arranged. <P>COPYRIGHT: (C)2004,JPO</p> |
