Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If heating units are arranged at different positions in a liquid cooling system, then the system can cover more heating areas, but the flow rates and heat dissipation efficiency become inconsistent among heating units
Solution Approach 1:
The patent designs the liquid passage lengths of all heating units to be equal, creating equipotential flow conditions. This ensures that cooling liquid flows through each heating unit at the same flow rate, eliminating the inconsistency caused by different positions in the cooling system.
2Ease of manufacture
If heating units have different liquid passage lengths, then the pipeline layout becomes simpler, but the flow rates and heat dissipation efficiency become inconsistent
Solution Approach 1:
The patent segments the cooling system into multiple independent heating unit modules, each with identical liquid passage lengths. This modular segmentation allows the system to maintain flow rate uniformity while accommodating different overall system configurations and heating areas.
3Productivity
If heating units operate at different temperatures due to flow rate variations, then individual heat dissipation may be optimized, but the temperature difference among heating units increases and service life decreases
Solution Approach 1:
The patent changes the critical parameter of liquid passage length to be uniform across all heating units. This parameter change ensures consistent flow rates and temperatures, optimizing heat dissipation efficiency while maintaining uniform service life across all heating units in the system.

AI summary
A liquid cooling system for cooling heating units each having an identical cooling flow channel includes a cooling liquid circulating supply device which is provided with a liquid supply port and a liquid return port and a pipeline system which includes a liquid supply pipe, a liquid return pipe, and a flow distribution subsystem. One end of the liquid supply pipe communicates with the liquid supply port, and the other end is connected to the flow distribution subsystem at a total flow distribution end. One end of the liquid return pipe communicates with the liquid return port, and the other end is connected to the flow distribution subsystem at a total liquid collection end. The flow distribution subsystem connects the total flow distribution end and the liquid inlet of each heating unit and connects the total liquid collection end and the liquid outlet of each heating unit.
