1Volume of moving object
If the control unit is integrated with the robot base, then the robot structure becomes more compact, but heat dissipation becomes more difficult
Solution Approach 1:
The control unit is segmented into separate functional modules (control circuit, energy consumption unit, power supply unit) that can be independently positioned and managed thermally within the integrated structure
Solution Approach 2:
Heat dissipation fins are introduced as intermediary structures between the heat-generating components and the surrounding environment, increasing the effective heat transfer surface area without increasing the overall robot volume
2Temperature
If high thermal conductivity materials are used for heat dissipation, then heat transfer efficiency improves, but manufacturing complexity increases
Solution Approach 1:
The heat dissipation fins are merged with the control unit housing as a single integrated component, eliminating the need for separate heat sinks or thermal management modules and simplifying assembly
Solution Approach 2:
The thermal conductivity parameter of the housing material is optimized by selecting materials with appropriate thermal properties, balancing heat dissipation efficiency with manufacturing feasibility and cost
