Abstract
Abstract A compact chlorine generation device generates chlorine and usually ozone. The device is water cooled. A power transformer has a housing thereabout in heat conductive contact therewith. A highly heat conductive metal frame is attached in direct efficient heat conductive relation with the housing. The frame has a conduit therethrough generally adjacent to the housing. A metal block has a semi-conductor power rectifier held in a cavity therein and in thermal contact therewith. The block is attached in direct heat conductive relation with the frame. A coolant is flowed through the conduit thereby cooling the transformer and the rectifier. A chlorine generating electric cell has an anode and a cathode which are connected to the respective DC output poles of the rectifier. The coolant which exits the conduit is led to the cell wherein it serves as the electrolyte. Outflow liquid from the cell and having an enhanced chlorine level dissolved therein is directed to a reservoir which may be a swimming pool, a health spa, a purified water supply, or the like. The chlorine content of the reservoir is thereby increased to provide a sterilizing and disinfecting action.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
191 words
A compact device for generating chlorine for sterilizing use in swimming pools, health spas, water supplies, and the like, comprising, in combination: a power transformer having a housing thereabout in heat conductive contact therewith; a highly heat conductive metal frame attached in direct efficient heat conductive relation with said housing, said frame having a conduit therethrough generally adjacent to said housing; a metal block having a cavity therein; a semi-conductor power rectifier held in said cavity in thermal contact with said block; means for attaching said block in direct heat conductive relation with said frame; means for flowing an aqueous coolant through said conduit for cooling said frame and thereby cooling both said transformer and said rectifier; a chlorine generating electrolytic cell having an anode and a cathode; means for connecting an output from said rectifier to said anode and said cathode; means for conducting said coolant into said cell where it serves as the electrolyte therein; and means for conducting overflow coolant having enhanced chlorine level therein from said cell to an aqueous liquid containing reservoir to increase the chlorine content in said reservoir and thereby provide a sterilizing action.
Claim 2
Dependent Claim
