Solution Overview

Problem

Existing room temperature control devices face inefficiencies in heat exchange due to small heat-transferring contact surfaces between heat transfer profiles and pipelines, leading to reduced heat transfer effectiveness and increased production costs.

Innovation Solution

The device features elongated heat transfer profiles with a U-shaped central section and thermally conductive contact profiles that ensure full-surface contact with both the base and legs, combined with a D-profile pipeline section for enhanced heat transfer, and includes sound absorbers and a supply air device for improved acoustics and airflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If aluminum extruded profiles are used to completely enclose the pipe, then heat transfer surface area is increased, but production time and cost increase significantly

Engineering Contradiction:
Improveheat transfer surface areaVSAvoidproduction efficiency
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

The heat transfer profile is divided into a base section and leg sections that can be separately manufactured and then assembled. This segmentation allows for more efficient production methods such as stamping and bending of sheet metal, replacing the time-consuming aluminum extrusion process while maintaining the enclosing function and heat transfer surface area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses composite construction with sheet metal components (base and leg sections) instead of solid aluminum extrusion. This composite approach combines the advantages of sheet metal forming efficiency with the structural integrity needed to enclose the pipe and provide adequate heat transfer surface area.

Inventive Principle:
Principle #40Composite materials

2Area of stationary object

If sheet metal profile halves are assembled to enclose the pipeline, then heat transfer surface area is increased, but continuous contact surface between profile and pipeline cannot be guaranteed

Engineering Contradiction:
Improveheat transfer surface areaVSAvoidheat transfer continuity
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

A contact profile is introduced as an intermediary element between the sheet metal heat transfer profile and the pipeline. This contact profile ensures continuous thermal contact by bridging the gap between the assembled profile halves and the pipe surface, guaranteeing reliable heat transfer continuity while maintaining the benefits of sheet metal construction.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If holding device is designed to click onto pipeline, then assembly is simplified, but heat-transferring contact surface becomes very small

Engineering Contradiction:
Improveassembly simplicityVSAvoidheat transfer contact surface
Core Design Contradiction:
Ease of manufactureVSArea of stationary object

Solution Approach 1:

The holding device and heat transfer profile functions are merged into a single integrated base section. The base section simultaneously provides the clicking mechanism for simple assembly and the large heat transfer surface area needed for effective thermal exchange, eliminating the need for separate holding devices with limited contact surfaces.

Inventive Principle:
Principle #5Merging (Combining)
