Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional single pump module is used for temperature control, then temperature control function is provided, but electrical current is high causing electromagnetic interference and large device size
Solution Approach 1:
The pump module is divided into multiple smaller pump modules (first pump module, second pump module, etc.) connected in series. This segmentation reduces the electrical current required for each individual module while maintaining the overall temperature control function, thereby reducing electromagnetic interference with electronic components.
2Reliability
If large pump module is used for temperature control, then sufficient cooling power is provided, but mechanical stress and heat flow increase
Solution Approach 1:
The temperature control system is segmented into multiple independent pump modules that can be distributed across different locations. This allows the cooling function to be provided with smaller, less stressful units rather than one large high-stress pump module, reducing mechanical stress and heat flow on individual components.
Solution Approach 2:
Different pump modules are positioned at specific locations (e.g., first pump module at first location, second pump module at second location) to provide localized temperature control. This enables precise cooling where needed while minimizing unnecessary mechanical stress and heat flow in other areas, improving overall system reliability.
3Measurement precision
If multiple pump modules are used for individual channel control, then precise temperature control is achieved, but device complexity increases
Solution Approach 1:
The channel system is divided into multiple independent channels (first channel, second channel, etc.), each with its own pump module. This segmentation enables precise independent temperature control of each channel while maintaining manageable system complexity through modular design, where each module can be controlled separately according to specific cooling requirements.
