Immersion Cooling Tank Layout for Uniform Coolant Flow Across Servers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersion cooling systems experience uneven heat dissipation due to non-uniform coolant flow rates, with coolant flowing slower near the outlet than further away, leading to inconsistent cooling of servers.
Innovation Solution
The immersion cooling tank design incorporates a liquid flow tube with adjusters and a cold source distributor that ensures uniform coolant flow by controlling the inflow and outflow through strategically positioned inlets and outlets, and optionally using driving members like fan blades to enhance coolant circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If coolant flows through the tank naturally without flow control, then the system structure is simple, but the coolant flow rate is uneven causing inconsistent cooling
Solution Approach 1:
The patent applies local quality by positioning multiple inlets and outlets at different locations throughout the tank, and by using adjustable flow controllers at each outlet. This creates locally optimized flow conditions in different regions of the tank, ensuring uniform coolant distribution and consistent cooling across the entire server surface rather than relying on a single centralized flow path.
Solution Approach 2:
The patent implements dynamics through adjustable flow controllers that can dynamically regulate coolant flow rates at different outlets. This dynamic control allows the system to adapt flow distribution based on varying thermal loads and operational conditions, maintaining optimal cooling uniformity while managing the complexity through controllable parameters rather than fixed rigid structures.
2Manufacturing precision
If multiple inlets and outlets are added to control flow distribution, then cooling uniformity improves, but the device complexity increases
Solution Approach 1:
The patent applies parameter changes by using adjustable flow controllers that can modify flow rate parameters at different outlets. This allows precise control over coolant distribution to achieve consistent cooling across the server, while the adjustability means the same hardware configuration can adapt to different operational requirements without requiring multiple fixed configurations.

Function Achieved in This Case
This design achieves uniform cooling of electronic devices by maintaining consistent coolant flow rates, effectively addressing the issue of uneven heat dissipation and ensuring efficient heat transfer across the server.
Implementation Method 1
the coolant 20 flows into the tank body 10 or out of the tank body 10 through the liquid flow tube 30
Implementation Method 2
the coolant adjacent to an outlet of the tank flows slower than the coolant further away from the outlet, which causes uneven dissipation of heat of the server

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.
