Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a liquid cooling system is used to dissipate heat from heating elements, then heat dissipation efficiency is improved, but liquid leakage risk increases which can cause damage to electronic devices

Engineering Contradiction:

Improveheat dissipation efficiencyVSAvoidliquid leakage risk

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

A liquid collection device is introduced as an intermediary component between the liquid cooling system and the electronic device. This collection device captures any leaked liquid before it can reach and damage the electronic device, thus resolving the contradiction between maintaining effective heat dissipation and preventing liquid leakage damage.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The liquid collection device is positioned in advance to catch potential liquid leaks before they cause harm. This preemptive measure cushions against the harmful effects of liquid leakage while allowing the liquid cooling system to continue operating at full heat dissipation efficiency.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Use of energy by moving object

If the liquid cooling body completely covers the heating element for better heat absorption, then heat exchange efficiency is improved, but the risk of liquid leakage onto the electronic device increases

Engineering Contradiction:

Improveheat exchange efficiencyVSAvoidliquid leakage harm

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The liquid collection device serves as a protective intermediary that allows the liquid cooling body to maintain full contact with the heating element for optimal heat exchange, while simultaneously preventing any leaked liquid from reaching the electronic device.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system is segmented into distinct functional zones: the liquid cooling body zone for heat exchange, the liquid collection device zone for leakage containment, and the electronic device zone for operation. This segmentation allows each component to perform its function independently without compromising the others.

Inventive Principle:

Principle #1Segmentation

3Volume of moving object

If the liquid cooling system uses small-sized components to reduce space occupation, then device compactness is improved, but the reliability against liquid leakage deteriorates

Engineering Contradiction:

Improvespace occupationVSAvoidleakage safety

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The liquid collection device is designed to nest around the liquid cooling body and multi-channel structure, forming a protective enclosure without significantly increasing the overall footprint. This nested configuration maintains device compactness while providing comprehensive leakage protection.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The liquid collection device employs a shell structure that flexibly adapts to the compact geometry of the liquid cooling components, providing effective leakage containment within a minimal volume that does not compromise device compactness.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A liquid cooling system for an electronic device is provided. The liquid cooling system includes a liquid guide tube, a liquid cooling body, a multi-channel structure, and a liquid collection device. The liquid cooling body and the multi-channel structure are communicated through the liquid guide tube. The liquid collection device continuously surrounds the multi-channel structure, the liquid guide tube, and the liquid cooling body, and has a window to expose a heated surface of the liquid cooling body. In the liquid cooling system for an electronic device, the liquid guide tube, the liquid cooling body, and the multi-channel structure are continuously surrounded, which can effectively collect the leaking liquid in all areas, and sufficiently prolong the duration of continuous operation of the electronic device after the leakage of the liquid cooling system.
