What liquid is inside a water cooled radiator is it toxic

The liquid used in water-cooled radiators may be water or distilled water, non-toxic.

Because the entire water-cooled system in the radiator, pumps, suction box, hoses, etc. are used in copper, aluminum, welding material system PVC hoses, etc., so many kinds of material system together, such as the use of ordinary distilled water and deionized water, after a period of time will become a weakly acidic liquid cold, long time to use will make the metal structure of the rust, a serious impact on the cooling system's heat dissipation function.

Radiator is a series of devices used to conduct, release heat collectively. Radiators are mainly heating radiators, computer radiators, of which heating radiators can be divided into a number of types according to the material and mode of operation, computer radiators can be divided into a number of types according to the use and installation methods.
