Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersion cooling systems experience uneven heat dissipation due to varying coolant flow rates, leading to non-uniform cooling of servers.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If coolant flows through the tank without flow control, then the cooling system is simple, but the coolant flow rate is uneven causing non-uniform heat dissipation
Solution Approach 1:
The liquid flow tube is divided into multiple segments with individual adjusters, allowing independent control of coolant flow at different locations. This segmentation enables uniform distribution of coolant across the server components, resolving the non-uniform heat dissipation issue while maintaining manageable system complexity through modular design
Solution Approach 2:
Adjusters are placed at specific locations along the liquid flow tube to locally control coolant flow rates. This local quality approach allows precise regulation of flow distribution to match the thermal load distribution of server components, achieving uniform heat dissipation without requiring complete system redesign
2Productivity
If coolant flow rate is increased to improve cooling efficiency, then heat dissipation improves, but flow uniformity decreases causing uneven cooling
Solution Approach 1:
The adjusters enable dynamic control of coolant flow rates at different locations along the liquid flow tube. This dynamic adjustment capability allows the system to optimize both overall cooling efficiency and local flow uniformity simultaneously, resolving the contradiction between high cooling performance and even temperature distribution
Solution Approach 2:
By changing the flow resistance parameters through adjustable components, the system can regulate coolant flow distribution. This parameter adjustment allows maintaining high overall flow rates for efficient cooling while ensuring uniform local distribution for even temperature across server components

AI summary
An immersion cooling tank includes a tank body and a liquid flow tube. The tank body holds a coolant and an electronic device. The tank body defines an inlet and an outlet. The inlet and the outlet are respectively located at opposite ends of the electronic device for inputting and outputting the coolant. The coolant flows through the electronic device. The liquid flow tube includes at least one adjuster. The liquid flow tube is located inside the tank body and coupled to at least one of the inlet or the outlet. The at least one adjuster faces the electronic device for controlling an amount of the coolant flowing in or out of the tank body.
