Immersion Cooling Tank Adjusters for Uniform Server Coolant Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersion cooling systems for servers suffer from uneven heat dissipation due to non-uniform coolant flow rates, leading to inconsistent cooling performance.
Innovation Solution
The immersion cooling tank incorporates a liquid flow tube with adjusters to control the coolant flow, ensuring uniform distribution around the server, and optionally uses driving members like fan blades to enhance coolant flow.
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 inconsistent cooling performance
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 precise flow rate adjustment to achieve uniform cooling across the server while maintaining manageable system complexity through modular design
Solution Approach 2:
Different sections of the liquid flow tube are equipped with adjustable flow controllers that can be tuned independently based on local cooling requirements. This local quality approach ensures that each region of the tank receives appropriate coolant flow rates, achieving uniform cooling performance without requiring complete system redesign
2Temperature
If coolant flows naturally in the tank, then the system requires minimal components, but the coolant adjacent to the outlet flows slower causing uneven heat dissipation
Solution Approach 1:
The flow control system incorporates adjustable components that can be dynamically tuned to optimize coolant flow rates at different locations. This dynamic adjustment capability allows the system to compensate for natural flow variations and maintain consistent coolant speed throughout the tank, ensuring uniform temperature distribution
Solution Approach 2:
The adjustable flow controllers can be configured based on observed cooling performance, creating a feedback mechanism where flow rates are optimized to achieve desired temperature uniformity. This feedback approach corrects the natural tendency for slower flow near the outlet by adjusting local flow rates to achieve overall consistency

Function Achieved in This Case
This configuration achieves uniform cooling of servers by ensuring consistent coolant flow rates, thereby preventing hotspots and ensuring efficient heat dissipation.
Implementation Method 1
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
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.
