Solution Overview

Problem

Conventional heat exchanger designs require separate manufacturing and assembly with components, limiting material choices and maintenance accessibility, and often result in inefficient use of space and increased material usage.

Innovation Solution

An integrated heat exchanger design where the housing is combined with the component housing, allowing for a removable core that can be easily maintained, inspected, or replaced, and manufactured from different materials, with fluid paths formed integrally within the housings to reduce external plumbing and enhance thermal efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the heat exchanger is designed as a separate component with external plumbing, then the heat exchanger can be manufactured independently, but the device complexity and material usage increase

Engineering Contradiction:
Improveindependent heat exchanger manufacturingVSAvoidexternal plumbing connections
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent integrates the heat exchanger housing with the component housing into a single unified structure. The heat exchanger housing is formed as an integral part of the component housing, eliminating the need for separate manufacturing and external plumbing connections. This merging reduces device complexity while maintaining manufacturing feasibility through integrated forming processes.

Inventive Principle:
Principle #5Merging (Combining)

2Loss of energy

If the heat exchanger core is permanently integrated into the housing, then the thermal efficiency is maximized, but the ease of repair and maintenance deteriorates

Engineering Contradiction:
Improvethermal efficiencyVSAvoidcore maintenance accessibility
Core Design Contradiction:
Loss of energyVSEase of repair

Solution Approach 1:

The heat exchanger is divided into two distinct segments: a permanent housing that remains integrated with the component, and a removable core that can be easily extracted. The housing contains fluid paths and mounting structures, while the core contains the heat exchange surfaces. This segmentation allows the core to be removed for maintenance while the housing remains, enabling easy repair without compromising the integrated thermal design.

Inventive Principle:
Principle #1Segmentation

3Loss of substance

If the heat exchanger housing is integrated with the component housing, then the material usage is reduced, but the adaptability of the heat exchanger core construction is limited

Engineering Contradiction:
Improvematerial usage reductionVSAvoidcore material and construction choices
Core Design Contradiction:
Loss of substanceVSAdaptability or versatility

Solution Approach 1:

By separating the housing from the core, the patent enables different materials and construction methods to be used for each part. The housing can be made from a material optimized for structural integration with the component, while the core can be manufactured from materials and processes (such as additive manufacturing) optimized for heat exchange performance. This segmentation maintains design freedom for the core despite the integrated housing.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If external plumbing is used to connect the heat exchanger, then the heat exchanger can be independently designed, but the packaging efficiency and space utilization deteriorate

Engineering Contradiction:
Improveindependent heat exchanger designVSAvoidpackaging space utilization
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The heat exchanger housing is merged with the component housing to form a single integrated assembly. Fluid paths are formed within the integrated housing structure, eliminating the need for external plumbing connections. This integration significantly reduces the overall volume required for packaging, as the heat exchanger occupies space within the component housing rather than requiring separate external connections and routing space.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A component 10 that generates or requires heat includes a heat exchanger 16 integrated with the component 10. The component 10 includes a component housing 12 holding functional parts 14 of the component, and the heat exchanger 16 has a heat exchanger housing 18 formed integrally with the component housing 12. There is a first fluid circuit in which a first fluid flows through the component 10 in a heat exchange relationship with the functional parts 14, into the heat exchanger 16 via a first fluid inlet 22, through the heat exchanger 16, out of the heat exchanger 16 via a first fluid outlet 24, and back to the functional parts 14 of the component 10. The heat exchanger 16 has a second fluid inlet 26 and a second fluid outlet 28 for connection into a second fluid circuit in which a second fluid flows from outside of the component 10 into the component housing 12 and into the heat exchanger 16 via the second fluid inlet 26, out of the heat exchanger 16 via the second fluid outlet 28 and out of the component housing 12. The heat exchanger housing 18 contains a removable heat exchanger core 20 for exchange of heat between the first fluid in the first fluid circuit and the second fluid in the second fluid circuit, with the heat exchanger core 20 being separate to the heat exchanger housing 18 and removable from the heat exchanger housing 18 during maintenance operations.
