Solution Overview

Problem

Existing cooling systems for heat-generating components, such as computer processors, often require complex setups and multiple connections to manage varying heat removal requirements, which can complicate the cooling process and increase costs.

Innovation Solution

A manifold element with interdigitated inlet and outlet channels on its upper surface is used to control the flow of a cooling fluid, allowing it to match the specific heat removal requirements of each component by adjusting flow restrictions, enabling efficient cooling of multiple components with a single fluid flow path, either in series or parallel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate cooling connections are used for each heat generating component, then each component can be cooled according to its specific heat removal requirement, but the system complexity and number of connections increase

Engineering Contradiction:
Improveheat removal effectivenessVSAvoidnumber of connections
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple cooling connections into a single manifold element that distributes cooling fluid to multiple heat generating components through integrated inlet and outlet channels. This merging approach maintains the ability to cool each component according to its specific heat removal requirements while reducing the total number of external connections needed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The manifold element serves multiple functions simultaneously: it distributes cooling fluid to multiple components, provides flow restrictions for each component, and collects cooled fluid from all components through a single integrated structure. This multi-functionality eliminates the need for separate cooling systems for each component.

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

2Device complexity

If a single cooling fluid flow path is used for multiple components, then the system complexity is reduced, but it becomes difficult to meet different heat removal requirements of each component

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The manifold element incorporates local flow restrictions at each outlet channel that can be individually adjusted to match the specific heat removal requirements of each heat generating component. This local customization within a unified structure allows each component to receive the appropriate cooling flow rate while maintaining a single external fluid connection.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The flow restrictions in the manifold element can be dynamically adjusted or designed with varying characteristics to accommodate different heat removal demands of various components. This dynamic adaptability enables a single flow path to serve multiple components with diverse cooling requirements.

Inventive Principle:
Principle #15Dynamics

AI summary

An assembly for cooling heat generating components, such as power electronics, computer processors and other devices. Multiple components may be mounted to a support and cooled by a flow of cooling fluid. A single cooling fluid inlet and outlet may be provided for the support, yet multiple components, including components that have different heat removal requirements may be suitably cooled. One or more manifold elements may provide cooling fluid flow paths that contact a heat transfer surface of a corresponding component to receive heat.
