PURPOSE: A cooling system is provided to improve the productivity, reduce the manufacturing cost, and improve the cooling efficiency by simplifying the manufacturing of a spiral shaped cooling channel inside the cooling system of a hollow cylinder type and by easily manufacturing the process. CONSTITUTION: A cooling system (100) is able to coat and install the carbon fiber composite material (40) on the outer side of a housing main body (10"), by surrounding the carbon fiber textile and the carbon fiber thread on the outer surface of a helical structure (10') and the outer side of the coupling ends (61,62).
