Thermal Design and Thermal Analysis of Control Cabinet for Pattern Sewing Machine

Thermal design and thermal analysis of control cabinet for pattern sewing machine was researched to make components’ temperature meets the requirement. Basic flow sheet of research process was introduced. Then, preliminary thermal design and thermal analysis was performed, and the computed result indicated that temperature of some components was out of limit. Next, by optimizing the location of fan and components in cabinet, the temperature of servo driver 1 to 3 dropped 11.1 oC, 10.8 oC and 11.3 oC respectively. The data shows that cabinet’s heat dissipation is improved, and the thermal design of the cabinet is reasonable. Finally, Thermal test of the prototype was performed, which proves the thermal design is effective, and the numerical simulation result is correct.
