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 Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If customized cooling loops are implemented for expansion components, then cooling effectiveness is improved, but system complexity and cost increase

Engineering Contradiction:
Improvecooling effectivenessVSAvoidsystem complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The fluid coupling is designed to perform multiple functions: it serves as a simple bypass connection when no expansion component is installed, and automatically switches to direct coolant flow to expansion components when they are installed. This eliminates the need for separate customized cooling loops while maintaining cooling effectiveness.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically detects the presence of expansion components and self-adjusts the coolant flow path without requiring external control or customization. The fluid coupling inherently redirects flow based on installation configuration, reducing system complexity.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If expansion components are added or removed, then system adaptability is improved, but coolant flow rate becomes insufficient

Engineering Contradiction:
Improvesystem adaptabilityVSAvoidcoolant flow rate
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The fluid coupling dynamically adjusts the coolant flow path based on the installation state of expansion components. When expansion components are installed, the coupling automatically redirects coolant flow to them; when removed, it redirects flow through the bypass path, ensuring optimal flow rates are maintained regardless of system configuration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system provides automatic feedback response to the presence or absence of expansion components through the mechanical configuration of the fluid coupling itself. The physical state of component installation directly controls the flow path, ensuring coolant flow rate adapts to system needs without external intervention.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If manual switching of bypass paths is required, then flow control precision is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveflow control precisionVSAvoidease of operation
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The fluid coupling automatically performs the switching function based on the installation state of expansion components, eliminating the need for manual operation. The system self-regulates the bypass path configuration, maintaining flow control precision while dramatically improving ease of operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The fluid coupling acts as an automatic intermediary mechanism that translates the physical presence or absence of expansion components into corresponding flow path configurations. This automatic mediation eliminates manual switching requirements while maintaining precise flow control.

Inventive Principle:
Principle #24Intermediary (Mediator)

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.
