Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling systems for information processing devices face challenges in efficiently cooling expansion components due to the need for customized cooling loops, which increase costs and limit upgradability, and result in insufficient coolant flow rates when expansion components are added or removed.
Innovation Solution
A modular liquid cooling infrastructure using 3-way fluid couplings that automatically switch between expansion-present and expansion-absent states based on the presence of expansion loops, ensuring optimal coolant flow rates by diverting liquid flow through the expansion loop when installed and the bypass path when not.

Engineering Contradiction Analysis
1Temperature
If customized cooling loops are used for expansion components, then cooling effectiveness is improved, but system complexity and cost increase
Solution Approach 1:
The fluid coupling body is designed to perform multiple functions: it serves as a simple bypass connection when no expansion loop is installed, and automatically switches to route coolant through the expansion loop when one is installed. This universal design eliminates the need for separate customized cooling loops for different configurations, reducing system complexity while maintaining cooling effectiveness.
Solution Approach 2:
The fluid coupling incorporates a movable poppet that dynamically switches between two positions based on the presence of an expansion loop. In the first position, coolant flows directly through the bypass path; in the second position, coolant is directed through the expansion loop. This dynamic adaptation allows the system to optimize cooling effectiveness for expansion components without requiring permanent complex infrastructure.
2Adaptability or versatility
If expansion loops are selectively installed, then system adaptability is improved, but coolant flow rate becomes insufficient when expansion components are added or removed
Solution Approach 1:
The movable poppet dynamically adjusts the coolant flow path based on the presence or absence of expansion loops. When expansion loops are installed, the poppet switches to direct coolant flow through them, ensuring adequate flow rates. When removed, the poppet returns to the bypass path, maintaining proper flow rates for the base system. This dynamic adjustment prevents flow rate insufficiency that would occur with fixed configurations.
Solution Approach 2:
The fluid coupling automatically detects the presence or absence of expansion loops and self-adjusts the coolant flow distribution without external intervention. The movable poppet responds to the physical state of the system, ensuring optimal coolant flow rates are maintained regardless of whether expansion components are installed, eliminating the need for manual flow rate adjustments.
3Manufacturing precision
If manual switching of bypass paths is required, then flow control precision is improved, but ease of operation deteriorates
Solution Approach 1:
The fluid coupling performs the switching operation automatically through the movable poppet mechanism that responds to the presence or absence of expansion loops. This self-service operation eliminates manual intervention entirely, greatly improving ease of operation while maintaining precise flow control through the mechanically actuated poppet position changes.
Solution Approach 2:
The movable poppet acts as an intermediary element that automatically mediates between the two possible system configurations (with or without expansion loops). It translates the physical state of expansion loop installation into the appropriate coolant flow path, providing precise flow control without requiring manual operation. The poppet serves as a self-actuating intermediary that simplifies user interaction while maintaining flow control precision.

AI summary
A 3-way fluid coupling for an information processing device having a primary liquid cooling loop and an expansion space. When no expansion device is present, the coupling directs liquid down a bypass path of the primarily loop. When an expansion device is present in the expansion space, the coupling directs liquid to flow through an expansion liquid cooling loop of the expansion device while substantially blocking liquid from flowing through the bypass path. The 3-way fluid coupling has a body and a poppet in the body. The poppet moves between a first position, in which first and second ports of the body are open while a third port is closed, thus directing liquid along the bypass path, and a second position in which the first and third ports are open and the second port is blocked, thus directing liquid to the expansion loop and substantially blocking the bypass path.
