R-113, which is the first component of the cooling liquid of the present invention, enhances the cooling effect of the cooling liquid and lowers its boiling point, and also lowers its viscosity and provides good fluidity. It also serves to improve the compatibility between the fluorinated oil and the mineral oil, synthetic oil, and silicone oil that constitute the other components of the cooling liquid of the present invention. The mixing ratio in the cooling liquid needs to be 2 to 50% by weight. If this blending ratio is less than 211 L'tsrs, it will not be able to fulfill the above-mentioned role sufficiently, and if it exceeds 50 L'tsrs, the boiling point will drop too much, making it unsuitable for use in high pressure equipment, etc. It is not suitable and also causes material deterioration due to its chemical action.

It is necessary that the content is 2 to 96% by weight. If the blending ratio is less than 2ffiM%, there is no effect of suppressing the generation of bubbles, and if it exceeds 96%, the heat transfer coefficient decreases significantly and the viscosity increases. In addition, these plants have 4i, which suppresses the chemical f'y activity of ζ-113, but the effect is insufficient at less than 2ntmiφ (:1).
