Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an integrated structure liquid cooling heat dissipation apparatus is used, then heat dissipation effectiveness is improved, but adaptability to different chip specifications deteriorates

Engineering Contradiction:
Improveheat dissipation effectivenessVSAvoidadaptability to different chip specifications
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The heat dissipation apparatus is divided into separate modules: a mounting base, a heat-conducting plate, and a pressing plate. These modules can be independently selected and combined based on different chip specifications, allowing the system to maintain effective heat dissipation while adapting to various chip sizes and thermal requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting base and pressing plate are designed as universal components that can accommodate multiple chip specifications. The mounting base includes a positioning structure that can adapt to different chip dimensions, and the pressing plate applies uniform pressure across various chip sizes, enabling a single set of these components to serve multiple heat dissipation configurations.

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

2Adaptability or versatility

If different liquid cooling heat dissipation apparatuses are designed for various chip specifications, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability to different chip specificationsVSAvoidcomplexity of multiple apparatus specifications
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By segmenting the heat dissipation apparatus into standardized modules (mounting base, heat-conducting plate, pressing plate), the system reduces complexity. Instead of designing entirely different apparatuses for each chip specification, only the heat-conducting plate needs to be varied, while the mounting base and pressing plate remain standardized across all configurations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting base and pressing plate serve as universal components across all chip specifications, reducing the number of unique parts needed. This modular approach allows a single set of mounting and pressing plates to work with multiple heat-conducting plates of different sizes, thereby simplifying the overall system complexity.

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

3Adaptability or versatility

If different liquid cooling heat dissipation apparatuses are designed for various chip specifications, then adaptability is improved, but production difficulty increases

Engineering Contradiction:
Improveadaptability to different chip specificationsVSAvoidproduction difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Segmenting the apparatus into standardized modules simplifies manufacturing. The mounting base and pressing plate can be mass-produced as standard components, while only the heat-conducting plate requires customization based on chip specifications. This significantly reduces production complexity compared to manufacturing entirely different apparatuses for each chip type.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The universal mounting base and pressing plate can be produced using the same manufacturing processes and tooling for all chip specifications, reducing setup costs and production complexity. Only the heat-conducting plate requires variant production, making the overall manufacturing process more efficient and scalable.

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

AI summary

This application provides a heat dissipation apparatus, a device, a rack, and a system. The heat dissipation apparatus mainly includes a heat-conducting plate, where a liquid channel is disposed on a first surface of the heat-conducting plate; a mounting base, where an accommodation cavity configured to accommodate a partial area that is in the heat-conducting plate and that includes a second surface is disposed on the mounting base, and the first surface and the second surface are disposed opposite to each other; and a pressing plate, configured to fasten the heat-conducting plate in the accommodation cavity, where the pressing plate is detachably and firmly connected to the mounting base, a sealing cavity is formed between the pressing plate and the first surface of the heat-conducting plate, the sealing cavity is configured to accommodate the liquid channel, and a liquid inlet connector and a liquid outlet connector that are connected to the liquid channel are disposed on the pressing plate. In the foregoing structure, the entire heat dissipation apparatus uses a modularized standard separated structure, and the pressing plate and the mounting base may be made into standard parts. When heat dissipation is performed on chips having different heat dissipation requirements, only a corresponding heat-conducting plate needs to be selected as required, and the mounting base and the pressing plate may still be used. This improves adaptability of the heat dissipation apparatus.
