Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large cooling tank is used for conventional immersion cooling, then heat dissipation efficiency is improved, but ease of repair deteriorates
Solution Approach 1:
The cooling system is divided into multiple independent cooling modules, each capable of operating separately. This segmentation allows individual modules to be removed and repaired without draining the entire cooling tank, thus maintaining heat dissipation efficiency while significantly improving ease of repair.
Solution Approach 2:
The electronic equipment is extracted from the conventional large cooling tank and placed into individual cooling modules. This extraction enables the equipment to be easily removed from its cooling module for repair while the module remains in the cooling tank, resolving the contradiction between maintaining cooling efficiency and enabling easy repair.
2Ease of operation
If the entire rack is hung out for repair, then access to internal parts is improved, but productivity deteriorates
Solution Approach 1:
The electronic equipment is extracted from the cooling liquid by removing only the specific module containing the equipment, rather than draining the entire tank and removing the whole rack. This provides sufficient access to internal parts for repair while minimizing system downtime and maintaining productivity.
Solution Approach 2:
The system is segmented into independent cooling modules, each housing specific electronic equipment. This segmentation allows targeted removal of only the module requiring repair, providing full access to internal parts without the need to halt the entire cooling system or remove the complete rack structure.
3Ease of operation
If cooling liquid is drained for repair, then access to equipment is improved, but loss of substance increases
Solution Approach 1:
The electronic equipment is extracted from the cooling liquid by removing only the specific module, allowing access to equipment without draining the cooling liquid from the tank. This eliminates the loss of cooling substance while providing necessary access for repair operations.
4Reliability
If a large cooling tank is used, then cooling capacity is improved, but device complexity increases
Solution Approach 1:
The large cooling tank is segmented into multiple independent cooling modules that can be individually managed. This segmentation maintains the overall cooling capacity of the system while reducing the operational complexity of each individual module, making the system easier to maintain and repair.

Function Achieved in This Case
Facilitates efficient and cost-effective maintenance and expansion of cooling systems, allowing single module repair without affecting others, with improved liquid circulation and reduced maintenance costs.
Implementation Method 1
The temperature of the cooling liquid can be made uniform based on the convection or stirring of the cooling liquid
Implementation Method 2
When the electronic equipment generates heat during operation, the heat will be transferred to the surrounding cooling liquid

AI summary
The disclosure describes an immersion cooling module, a multilayered immersion cooling system, and a method thereof. The immersion cooling module includes a main tank and an overflow plate. The partition divides the main tank into a liquid storage tank and a temporary storage tank. The top of the liquid storage tank is provided with a liquid inlet. The liquid storage tank may accommodate a cooling liquid and a module to be cooled. The bottom of the temporary storage tank is provided with a liquid outlet. The overflow plate is arranged in the main tank. When the top of the cooling liquid is higher than that of the overflow plate, the cooling liquid flows from the liquid storage tank to the temporary storage tank over the top of the overflow plate, and finally discharges from the liquid outlet, thereby generating the flow of the cooling liquid.
