Engineering Contradiction Analysis
1Speed
If the oil pump injecting distance is increased to increase the circulation speed of the coolant, then the circulation speed is improved, but the power consumption of the pump is increased and the partial flow velocity for high heat generating devices is limited
Solution Approach 1:
The patent applies local quality by introducing a convection accelerator specifically positioned around heat generating devices to enhance coolant flow velocity locally, rather than uniformly increasing circulation speed system-wide. This targeted approach improves heat dissipation efficiency at critical locations without proportionally increasing overall pump power consumption.
Solution Approach 2:
The convection accelerator introduces dynamic elements that actively modify coolant flow patterns around heat generating devices. The accelerator creates localized flow acceleration and turbulence, dynamically adjusting the coolant distribution to prioritize high-heat-area regions without requiring proportional increases in pump power.
2Productivity
If the quantity of heat dissipation devices is increased to improve heat dissipation efficiency, then the heat dissipation efficiency is improved, but the device complexity is increased
Solution Approach 1:
The convection accelerator serves multiple functions: it accelerates coolant flow, enhances convection intensity, and improves heat dissipation efficiency simultaneously. By integrating this multi-functional component, the patent achieves improved heat dissipation performance without proportionally increasing the quantity of separate heat dissipation devices.
Solution Approach 2:
The convection accelerator acts as an intermediary component that mediates between the coolant supply system and the heat generating devices. It enhances the effectiveness of the existing coolant flow without requiring additional heat dissipation devices, thereby improving heat dissipation efficiency while controlling device complexity.
3Productivity
If the contact heat resistance between the heat generating device and the heat dissipation devices is reduced to improve heat dissipation efficiency, then the heat dissipation efficiency is improved, but the manufacturing precision is increased
Solution Approach 1:
The convection accelerator utilizes vibration mechanisms to enhance coolant flow and convection intensity around heat generating devices. This vibrational approach improves heat dissipation efficiency through dynamic flow enhancement rather than relying solely on precise static contact heat resistance control, thereby reducing the manufacturing precision requirements.
