A cooling system for a high voltage system can include a high voltage supply and an electrical component coupled to the high voltage supply. The electrical component can generate heat that needs to be dissipated. The cooling system can include a cooling mechanism for dissipating the heat. The cooling mechanism can include a liquid conduit thermally coupled to the electrical component. The liquid conduit can contain a cooling solution comprising an alcohol having the formula R-OH, wherein R is a hydrocarbon having the formula C.sub.nH.sub.2n+1 and n is any positive integer between 1 and 6. The cooling system can additionally include a pump and a heat exchanger, each of which may be coupled to the liquid conduit.
