Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cooling systems for heat-generating electronic devices lack dynamic control over coolant flow, failing to account for variable heat dissipation patterns and thermal resistances across different components, leading to inefficient heat management and potential damage from temperature cycling.
Innovation Solution
Implementing multiple independently controllable flow adjusters within the device that can dynamically alter coolant flow impedance in response to temperature changes, allowing for localized temperature control and tailored cooling solutions for different components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a same active cooling source is used to flow coolant through a group of servers, then device complexity is reduced, but adaptability to different cooling needs of individual servers deteriorates
Solution Approach 1:
The patent divides the cooling system into segmented units by placing individual flow adjusters in each server's coolant channel. Each flow adjuster can independently control flow impedance for its respective server, allowing tailored cooling without requiring separate cooling sources for each server. This segmentation enables localized flow control while maintaining a shared cooling infrastructure.
Solution Approach 2:
The patent implements local quality by enabling each server to have customized flow impedance characteristics through its dedicated flow adjuster. Each component can be configured with different flow resistance values matched to its specific thermal requirements, allowing optimal cooling performance for each server's unique heat generation pattern while using a common cooling source.
2Device complexity
If coolant flow is uniformly distributed across all channels, then device complexity is minimized, but manufacturing precision of temperature control deteriorates
Solution Approach 1:
The patent applies parameter changes by allowing each flow adjuster to independently modify flow impedance parameters according to the specific thermal requirements of different servers or components. Each adjuster can be configured with different resistance values to optimize coolant flow distribution, enabling precise temperature control without complex active control systems.
3Adaptability or versatility
If actively controlled cooling systems are used with multiple flow adjusters, then adaptability to different cooling needs is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by designing flow adjusters that can be passively configured based on predetermined thermal requirements. The flow impedance settings can be established during manufacturing or installation without requiring active control systems, sensors, or power consumption. Each flow adjustor independently regulates its own channel's flow based on its configured parameters, eliminating the need for complex centralized control.

Implementation Method 1
selectively altering a first flow impedance within a first channel of the electronic device by changing a physical configuration of a first flow adjuster positioned in-line with the first channel
Implementation Method 2
a passively-controlled cooling system typically does not include a fan or coolant pump and is instead driven by natural conduction and/or convection processes that dissipate heat to a target heat outlet
Implementation Method 3
a passively-controlled cooling system typically does not include a fan or coolant pump and is instead driven by natural conduction and/or convection processes that dissipate heat to a target heat outlet

AI summary
A device cooling system includes a first flow adjuster positioned in-line with a first channel and a second flow adjuster positioned in-line with a second channel. The first flow adjuster is configurable to selectively adjust a first flow impedance within the first channel and the second flow adjuster is configurable to selectively adjust a second flow impedance within the second channel. The first flow impedance is independently adjustable relative to the second flow impedance.
