PURPOSE: An oil cooler of a power steering is provided to keep viscosity by decreasing temperature of oil with supplying oil to the steering system, and with changing the direction from pressure of oil. CONSTITUTION: An oil circulating cooling pipe(1) is installed between an oil pump and an oil compression cylinder, and a radiating fin(2) is mounted in the outside of the cooling pipe to cool oil in circulating. Plural cut parts are formed in the radiating fin for improving cooling efficiency. Plural inner fins are installed in the cooling pipe to form vortex in circulating, and a crease fin is fixed in the cooling pipe. Steering is performed actively by cooling oil with the cooling pipe and radiating fins. Vapor lock is prevented by keeping viscosity of oil, and cooling efficiency is improved with forming vortex.
