 Technical field

 The present invention relates to a cooling system for an ozone generator, and more particularly to a cooling system for a cellular ozone generator using tubular corona discharge.

 Background technique

 Ozone is a strong oxidant for sterilization, decolorization and odor removal. After disinfecting the environment, water, air, utensils and food, there is no secondary pollution harmful to the human body. At present, there are many methods for artificially producing ozone. According to the principle, there are mainly photochemical methods, electrochemical methods, atomic radiation methods, and corona discharge methods. Corona discharge methods include tubular, flat and other structural forms. Although oxygen molecules or oxygen atoms are ionized at normal temperature until the oxygen ions react with oxygen molecules to form ozone, the whole process needs to absorb a certain amount of heat. However, the higher the temperature, the faster the decomposition of ozone, and the ozone yield. Lowering, therefore, reducing the operating temperature of the ozone generator is an effective way to increase ozone yield. At present, the cooling methods for cooling the ozone generator mainly include liquid cooling and air cooling.
