Flow and thermal characteristics of cooling system for the robot controller were numerically as well as experimentally investigated. To obtain the overall flows within controller, the system level solutions were analysed at first and then the board level solutions were pursued to understand the detailed flow and temperature fields near the main board which have a significant influence on the cooling of electronic components. The evaluation for a performance of the heat exchanger was conducted on the basis of the obtained flow and temperature patterns. The results showed that the heat exchanger made a small contribution to the cooling of controller and caused an increase of the temperature in CPU.
