Solution Overview

Problem

Existing heat exchanger systems are not optimized for efficient heat transfer and compact structure, particularly in heat sources or sinks with fluid media, as they lack a configuration that maximizes the efficiency of heat exchange while minimizing space requirements.

Innovation Solution

The heat exchanger system incorporates line layers with spiral lines that alternate in flow direction, allowing for efficient heat transfer by having pairs of line layers with opposite flow circulation directions, and is designed to float within the fluid medium, using a housing with buoyancy bodies and optimized flow channels for convection-based operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If pipe layers are arranged at a significant distance from each other, then heat transfer efficiency is improved, but device volume increases

Engineering Contradiction:
Improveheat transfer efficiencyVSAvoiddevice volume
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The patent transitions from a planar arrangement to a three-dimensional stacked configuration with multiple pipe layers arranged vertically. Pipe layers are positioned at different heights (e.g., first pipe layer at a first height, second pipe layer at a second height), enabling heat transfer optimization without excessive volume increase by utilizing the vertical dimension for spacing while maintaining compact horizontal footprint.

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

Solution Approach 2:

Multiple pipe layers are nested within a single heat exchanger device, with each layer containing spiral pipes that are radially arranged around a central axis. The pipes in different layers are offset radially (e.g., first spiral pipe at a first radial distance, second spiral pipe at a second radial distance), creating a nested concentric structure that maximizes heat transfer surface area within a compact volume.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Productivity

If multiple spiral pipes run side by side in each pipe layer, then heat transfer efficiency is improved, but device complexity increases

Engineering Contradiction:
Improveheat transfer efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The heat exchanger is segmented into multiple pipe layers, with each layer containing one or more spiral pipes. This segmentation allows the complex heat transfer function to be distributed across multiple simpler modular units (individual spiral pipes in different layers), making the overall system more manageable while achieving high heat transfer efficiency through the combined surface area of all segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each spiral pipe layer serves the universal function of heat transfer between the process fluid and the surrounding medium. The repeated modular structure of spiral pipes across multiple layers provides a universal, scalable design where the same basic heat transfer unit (spiral pipe) is replicated and stacked to achieve the required total heat transfer capacity without increasing structural complexity.

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

3Ease of operation

If the heat exchanger unit is designed to float within the fluid medium, then ease of installation is improved, but structural stability may be compromised

Engineering Contradiction:
Improveease of installationVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The heat exchanger device incorporates buoyancy elements that provide an upward buoyant force to counteract the downward gravitational force on the device. This anti-weight mechanism enables the heat exchanger to float at a desired depth within the fluid medium, facilitating easy installation and removal while maintaining structural stability through force equilibrium between buoyancy and gravity.

Inventive Principle:
Principle #8Anti-weight (Counterweight)
