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
Engineering 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
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.
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.
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
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.
3Ease of manufacture
If holding device is designed to click onto pipeline, then assembly is simplified, but heat-transferring contact surface becomes very small
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.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration increases the heat transfer surface area, enhances stability, and maintains effective horizontal heat transfer without reducing the surface area for air flow, while also providing efficient sound absorption and adaptable manufacturing for cost-effectiveness.
Implementation Method 1
a contact profile (4) which is arranged between the heat transfer profile (3) and the pipeline section (5) and is in heat-transferring contact with both the heat transfer profile and the pipeline section
Implementation Method 2
at least one pipeline for the flow of a heat transfer medium, wherein at least one pipe section runs parallel to a longitudinal axis of a heat transfer profile and is coupled to the latter in a heat-transferring manner
Implementation Method 3
Due to the large area of the heat transfer profile, which is oriented towards the room, good heat transfer can be achieved by means of radiant heat exchange
Implementation Method 4
the heat transfer profile is clicked onto the pipeline through which the heat transfer medium flows. A heat exchange between the heat transfer medium and the heat transfer profiles takes place via the pipeline and the holding device attached to it
