Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersion cooling systems face inefficiencies in heat dissipation across servers due to inconsistent heat generation and coolant flow, leading to local overheating and increased pump power consumption.
Innovation Solution
A cooling system with an accommodating tank, turbulence plate, adjustment structure, and control mechanism that adjusts the flow direction and amount of coolant by moving an adjustment plate through a groove in the turbulence plate, ensuring optimal heat dissipation for servers at different positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If servers are directly disposed in the accommodating tank with uniform coolant flow, then the system structure is simple, but heat dissipation efficiency is inconsistent leading to local overheating
Solution Approach 1:
The liquid inlet space is segmented into multiple chambers by the adjustment plate, which divides the coolant flow into separate streams. This segmentation allows different regions of the tank to receive customized coolant flow rates, enabling consistent heat dissipation across servers at different positions without requiring a completely complex system redesign.
Solution Approach 2:
The adjustment plate is designed to be movable rather than fixed, allowing the system to dynamically adapt coolant distribution based on thermal conditions. This dynamic adjustment capability enables the system to optimize heat dissipation efficiency for different operational scenarios while maintaining a relatively simple overall structure.
2Temperature
If coolant flow rate is increased to prevent local overheating, then heat dissipation efficiency improves, but pump power consumption increases
Solution Approach 1:
Different chambers created by the adjustment plate receive different coolant flow rates tailored to the specific thermal requirements of servers in those regions. This local customization of coolant flow quality ensures adequate heat dissipation for high-heat servers without unnecessarily increasing flow rates throughout the entire system, thereby avoiding excessive pump power consumption.
Solution Approach 2:
The system changes the coolant flow rate parameter locally in different chambers rather than uniformly across the entire system. By adjusting the flow rate parameter only where needed to prevent local overheating, the system achieves improved heat dissipation efficiency without the penalty of increased overall pump power consumption that would result from a uniform flow rate increase.
3Ease of operation
If servers at different positions are cooled uniformly, then the cooling system is simple to control, but servers with different heat generation requirements experience inconsistent cooling
Solution Approach 1:
The adjustment plate segments the liquid inlet space into multiple controllable chambers, creating distinct flow zones that can be independently optimized for servers at different positions. This segmentation enables customized cooling for servers with different heat generation requirements while maintaining relatively simple control through a single adjustable component.

Implementation Method 1
The turbulence plate is disposed in the accommodating tank, to divide the accommodating tank into a liquid inlet space and a cooling space, the turbulence plate includes a groove, the groove divides the turbulence plate into a first plate portion and a second plate portion, and the first plate portion and the second plate portion are opposite to each other, and have a plurality of communication holes communicating the liquid inlet space with the cooling space.
Implementation Method 2
a server is directly immersed in a non-conductive coolant, and after thermal energy generated by components of the server is conducted to the coolant
Implementation Method 3
The control mechanism is disposed at the accommodating tank, and connected to the adjustment structure, where the control mechanism is adapted to control the adjustment plate to move between a first position and a second position, where when the adjustment plate moves from the first position to the second position, the adjustment plate passes through the groove and enters the liquid inlet space, to divide the liquid inlet space into a first chamber corresponding to the first plate portion and a second chamber corresponding to the second plate portion.
