An immersion cooling system with a storage tank, adapter frame, and electronic device configuration that allows vertical placement of electronic devices, featuring a first and second wire channel for power wire connection, facilitating easy installation and reducing coolant loss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional horizontal arrangement of server apparatuses is used, then installation in immersion cooling systems is simpler, but heat dissipation performance is compromised and coolant loss increases

Engineering Contradiction:
Improveinstallation simplicityVSAvoidheat dissipation performance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent transitions from traditional horizontal arrangement to vertical arrangement of electronic devices in the immersion cooling system. This dimensional change allows the devices to be positioned upright with their heat-generating components oriented vertically, improving heat dissipation efficiency while maintaining installation simplicity through the adapter frame design.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If vertical installation of electronic devices is implemented, then heat dissipation performance improves, but installation difficulty and complexity increase

Engineering Contradiction:
Improveheat dissipation performanceVSAvoidinstallation difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The adapter frame serves as an intermediary component between the electronic device and the immersion cooling system. It provides a standardized interface that simplifies the vertical installation process, allowing electronic devices to be easily mounted in the vertical position while maintaining good heat dissipation performance.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If vertical installation is adopted, then heat dissipation improves, but coolant loss increases

Engineering Contradiction:
Improveheat dissipation performanceVSAvoidcoolant loss
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent designs the liquid level in the immersion cooling system to be higher than the highest point of the vertically arranged electronic devices. This creates an equipotential condition where the coolant continuously covers the devices, preventing vaporization and reducing coolant loss while maintaining effective heat dissipation.

Inventive Principle:
Principle #12Equipotentiality
