This thesis focuses on enhancing the internal cooling mechanisms of ABB’s Omnicore V400XT control cabinets, which are integral to robotic operations. The research aims to mitigate thermal inefficiencies and eliminate hot spots by improving air distribution within the cabinets. SolidWorks flow simulations and experimental validationswere employed to assess various fan housing designs and air chamber configurations. Results indicate that the introduction of an elevated air chamber outlet significantly improves air distribution, ensuring higher air velocities across critical components. This modification also presents the challenge of air potentially exiting the chamber prematurely, thus reducing the cooling efficiency through convection and conduction. Experimental data corroborate that while the elevated air chamber outlet enhances air distribution, the overall average temperature within the cabinet remains largely unaffected by different fan designs. This suggests that the rotational force exerted by the fan directs airflow towards the cabinet walls rather than the components, limitingthe cooling efficiency. Tools such as Simscape and 3D printing were utilised for prototype development and testing. These findings provide a cost-effective approach to improving thermal management in robotic control cabinets, potentially setting a new standard for industrial applications. This comprehensive approach aims to enhance the efficiency and reliability of robotic control systems, contributing to the advancement of industrial automation.
