Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional standardized coolant distribution units are used, then the device complexity is reduced and installation is simplified, but the flow rate and static pressure are insufficient to meet increasing heat dissipation requirements
Solution Approach 1:
The system segments the coolant distribution function into multiple standardized CDU units that can be independently configured. Each CDU maintains standardized interfaces for ease of installation, while multiple units working together through serial/parallel connections achieve the required flow rate and pressure for high heat dissipation applications.
Solution Approach 2:
The adapting device introduces dynamic reconfigurability through switch valves that allow the system to switch between serial and parallel connection modes. This enables the same standardized components to adapt their configuration dynamically based on the required flow rate and pressure conditions, resolving the contradiction between standardized simplicity and performance requirements.
2Adaptability or versatility
If preset specification coolant distribution units are used, then manufacturing and installation are simplified, but adaptability to different cooling requirements is reduced
Solution Approach 1:
The adapting device serves multiple functions: it connects standardized CDU units in series to increase pressure, connects them in parallel to increase flow rate, and provides configuration flexibility through switch valves. This single universal device replaces the need for multiple specialized CDU designs, achieving adaptability without increasing manufacturing complexity.
Solution Approach 2:
The switch valves enable dynamic reconfiguration of the system architecture, allowing standardized units to adapt to different cooling requirements (different flow rates and pressures) without requiring custom-designed units for each application scenario.
3Productivity
If multiple coolant distribution units are connected to increase flow rate and pressure, then heat dissipation capability is improved, but the connection configuration becomes more complex
Solution Approach 1:
The adapting device acts as an intermediary between multiple standardized CDU units and the server cabinet manifolds. It provides standardized connection interfaces and automated switch valve control, simplifying the operation of connecting multiple units while enabling complex serial/parallel configurations to achieve the required flow rate and pressure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adapting device increases the flow rate and pressure of the coolant distribution system, enabling more effective heat dissipation and accommodating different cooling requirements without the need for specialized units, thus improving the heat dissipation capability and flexibility of the system.
Implementation Method 1
The switch valves are disposed on the casing and connected to the plurality of first liquid inlets, the plurality of first liquid outlets, the at least one second liquid inlet and the at least one second liquid outlet so as to change a connection among the plurality of first liquid inlets, the plurality of first liquid outlets, the at least one second liquid inlet and the at least one second liquid outlet
Implementation Method 2
When the coolant in a relatively low temperature flows through an electronic component in a relatively high temperature, it can directly absorb the heat energy to lower the temperature of the electronic component
Implementation Method 3
The liquid cooling uses coolant as a heat-dissipating medium and it is coupled with a pump to drive the coolant to form a continuous circulation in the applied system
Implementation Method 4
The coolant that absorbs heat will have a heat exchange in another area to release its heat energy and then be cooled down and flows back to the circulation
