Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single cooling water pipeline is used for heat dissipation, then the system structure is simple, but the inlet water temperature cannot be quickly adjusted to a user-defined range
Solution Approach 1:
The cooling water pipeline is divided into multiple independent branch pipelines (first cooling water branch pipeline, second cooling water branch pipeline, third cooling water branch pipeline), each with its own regulating valve. This segmentation allows independent control of water flow to different heat dissipation units, enabling quick adjustment of inlet water temperature to the user-defined range by coordinating the opening degrees of different valves.
2Manufacturing precision
If multiple regulating valves are used in parallel pipelines, then the inlet water temperature can be precisely controlled, but the system complexity increases
Solution Approach 1:
Each regulating valve in the parallel branch pipelines serves multiple functions: controlling water flow to specific heat dissipation units, adjusting inlet water temperature to user-defined ranges, and coordinating with other valves to achieve precise temperature control. The first regulating valve controls the temperature-stabilizing water branch pipeline, while the second and third regulating valves control the cooling water branch pipelines, enabling multi-functional temperature regulation.
3Loss of energy
If cooling water is used to absorb heat from network devices, then heat dissipation is achieved, but energy consumption increases
Solution Approach 1:
The system converts the heat generated by network devices from a harmful factor into a useful resource by using cooling water to absorb this heat. The heat absorption unit efficiently transfers heat from network devices to cooling water, which is then distributed through parallel branch pipelines to heat dissipation units. This approach not only achieves heat dissipation but also reduces energy consumption by utilizing the heat absorption capability of cooling water.
4Reliability
If the heat absorption unit absorbs heat from network devices, then stable operation is ensured, but the system requires precise temperature monitoring
Solution Approach 1:
The system implements temperature monitoring and feedback control through temperature acquisition units that detect the temperature of cooling water at different locations. The controller receives temperature data and adjusts the opening degrees of regulating valves accordingly to maintain inlet water temperature within the user-defined range. This feedback mechanism ensures stable operation of network devices while managing temperature monitoring complexity through automated control.
