Abstract: In order to contain the thermal expansion of a positioning device where a ball screw is used, a new type of water jacket with double spiral paths has been designed for cooling the mut directly by circulating the temperature-controlled cooling water. It was found that with the proper adjustment of the inlet temperature, it was possible to control the thermal expansion within Sum. Also, an experimental system was established to investigate the heat transfer characteristics of the cooling jacket. At current paper, in order to propose a cooling jacket with double screw paths with the best heat transfer performance, a simulation calculation based on Solidworks was carried out under different screw pitches and screw heights and flow rates. As a result of applying heat flux of 951W/m2 to the inner wall and conducting thermal analysis under various flow rate conditions, it was confirmed that the best cooling effect appeared when the spiral pitch is 6 mm and spiral height is 10 mm
