Solution Overview

Problem

Conventional heating and cooling panels have inefficiencies due to high water content, slow control response, and limited heat output, which can be improved by optimizing the wetted surface area and air cross-section while maintaining the panel's shape and construction.

Innovation Solution

The design features half-shells with elevations and depressions that create a thin flow path for the heat transfer fluid, ensuring almost complete wetting of inner surfaces for enhanced heat transfer, reduced fluid content, and a variable structure that allows for optimized flow characteristics and stability, with connecting knobs and spacers for cohesion and support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If conventional panel designs are used with larger fluid content, then the panel structure is simpler and more stable, but the control response speed is slow and heat output is limited

Engineering Contradiction:
Improvecontrol response speedVSAvoidfluid content
Core Design Contradiction:
SpeedVSQuantity of substance

Solution Approach 1:

The panel is divided into two separate half-shells that are connected, creating a segmented fluid pathway. This segmentation allows the fluid to flow through a more optimized path with larger wetted surfaces, improving heat transfer efficiency and control response without requiring a complete redesign of the entire panel structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces a third dimension by creating elevations and depressions that extend into the flow path from both half-shells. This dimensional addition increases the wetted surface area and optimizes the fluid flow path, enabling faster control response and improved heat output while managing fluid content efficiently.

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

2Productivity

If the wetted surface area is increased to improve heat output, then the heat transfer efficiency increases, but the panel complexity and manufacturing difficulty increase

Engineering Contradiction:
Improveheat outputVSAvoidpanel structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The elevations and depressions from both half-shells are merged together to form the complete flow path structure. This merging approach allows the complex wetted surface geometry to be achieved by combining two simpler half-shell components, each with complementary features that together create the optimized heat transfer surfaces.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Different regions of the panel have different structural characteristics - the half-shells have elevations and depressions in specific locations to maximize wetted surface area where heat transfer is most effective, while other regions maintain simpler structures for structural support and manufacturing ease.

Inventive Principle:
Principle #3Local quality

3Quantity of substance

If the flow path is made thinner to reduce fluid content, then the control inertia is reduced, but the structural stability and cohesion of the panel decreases

Engineering Contradiction:
Improvefluid contentVSAvoidpanel structural stability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The panel structure is segmented into two half-shells that can be manufactured and assembled separately. This segmentation allows the thin flow path structure to be achieved while maintaining structural integrity through the connection of two stable half-shell components rather than relying on a single thick-walled structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The panel uses a composite structure combining two half-shells with complementary elevations and depressions. This composite approach creates a stable structure with thin flow paths, as each half-shell provides structural support while the combined structure achieves the desired thin fluid pathway for reduced control inertia.

Inventive Principle:
Principle #40Composite materials

AI summary

The heater and cooler panel is formed with two profiled half-shells (H1,H2) connected with each other in their boundary areas. The half-shells are formed between two parallel collection channels. The flow path (S) for the working fluid is limited between the collection channels. The elevations towering from the inner surface of the connected half-shells and reversed from the flow path of the both half-shells protrude into the recesses in one half-shell. The recesses are formed in the inner surface of the opposite lying half-shell.
