Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a traditional radiator is used in the motor controller, then heat dissipation function is provided, but the radiator is difficult to install due to axial length and volume limitations of the control box
Solution Approach 1:
The radiator is divided into multiple independent radiator components, each with smaller volume, allowing them to be installed in limited spaces within the control box. Each radiator includes a mounting plate and heat dissipation plate, forming modular units that are easier to install than a single large radiator.
Solution Approach 2:
The radiator structure transitions from a traditional axial arrangement to a planar mounting configuration where the mounting plate attaches to the inner wall surface of the control box. This dimensional change allows the radiator to utilize the available wall space rather than consuming axial length, making installation easier and more adaptable to compact control box designs.
2Temperature
If a large-volume radiator is used, then heat dissipation capacity is improved, but the radiator is only suitable for a few motor structures, thus versatility is poor
Solution Approach 1:
The radiator design with mounting plate and heat dissipation plate configuration can be adapted to different control box sizes and motor structures. The modular nature allows the same basic radiator design to be used across various motor controller applications, improving versatility while maintaining heat dissipation effectiveness.
3Volume of moving object
If IGBT modules are installed on the radiator in a tight arrangement, then space utilization is improved, but the heat dissipation effect is poor
Solution Approach 1:
The heat dissipation plate provides a dedicated thermal management surface with optimized local properties for heat dissipation. The IGBT modules are mounted on this specialized surface which has enhanced thermal conduction characteristics, allowing efficient heat transfer from the modules to the radiator without requiring tight spacing that would compromise heat dissipation.
