Solution Overview

Problem

Existing ceiling radiator profiles face limitations in air distribution efficiency, particularly in cooling modes where condensation occurs, and they often require longer profiles to achieve desired cooling capacity, which can be material-intensive.

Innovation Solution

A ceiling radiator profile design featuring two parallel radiant surfaces connected via convex connecting webs, forming air ducts that utilize the Coandă effect for enhanced air distribution and condensation management, allowing for the use of cooling liquids below the dew point, thereby increasing cooling capacity or reducing profile length while saving material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional ceiling radiator profiles are used with separate tubes and radiant panels, then the structure is simple to manufacture, but the air distribution efficiency is poor and condensation cannot be effectively removed

Engineering Contradiction:
Improvestructural simplicityVSAvoidair distribution efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent combines the tube, connecting web, and radiant panels into an integrated extruded profile structure. The tube is arranged in the connecting web which connects two parallel radiant panels, forming a unified component that is manufactured as a single extruded piece. This merging maintains manufacturing simplicity while enabling sophisticated air distribution through the integrated design of air ducts within the profile.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces air ducts as a third dimension within the profile structure, formed by the space between the radiant panels and the tube arrangement in the connecting web. This internal three-dimensional air duct configuration enables effective air distribution and condensation removal without adding external complexity to the overall profile structure.

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

2Power

If longer ceiling radiator profiles are used to increase cooling capacity, then more cooling power is achieved, but more material is consumed and installation becomes more complex

Engineering Contradiction:
Improvecooling capacityVSAvoidmaterial consumption
Core Design Contradiction:
PowerVSLoss of substance

Solution Approach 1:

The patent changes the internal flow parameters by designing optimized air ducts within the profile that enhance air distribution efficiency. The convex connecting webs and strategically positioned tubes create effective Coandă effects that improve air flow patterns, allowing shorter profile lengths to achieve the same cooling capacity, thereby reducing material consumption.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a controlled air flow environment within the profile using the air ducts formed by the connecting webs and radiant panels. This internal air channel system efficiently manages air distribution and condensation removal, maximizing the cooling capacity per unit length of profile and reducing the total material needed.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

3Power

If cooling liquid temperature is reduced below dew point to increase cooling capacity, then cooling efficiency improves, but condensation forms on the profile surfaces

Engineering Contradiction:
Improvecooling capacityVSAvoidcondensation formation
Core Design Contradiction:
PowerVSObject-generated harmful factors

Solution Approach 1:

The patent extracts condensation from the problem by providing dedicated air ducts that actively remove moisture from the profile surfaces. The air flow system pulls condensation away from the cold surfaces where it forms, preventing water accumulation and allowing the use of sub-dew-point cooling temperatures to maximize cooling capacity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The air ducts act as an intermediary system between the condensation formation sites on the radiant panels and the external environment. These ducts facilitate the removal of condensation by channeling air flow that captures and transports moisture away from the cold surfaces, enabling effective use of low-temperature cooling.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Device complexity

If air is supplied at only a few points in the profile, then the air distribution system is simple, but the air release along the profile length is insufficient

Engineering Contradiction:
Improveair supply system complexityVSAvoidair release distribution
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent prepares the air distribution system in advance by designing pre-formed air ducts within the extruded profile structure. These internal channels are built into the profile during manufacturing, creating ready-made pathways that guide air from supply points along the entire length of the profile, enabling efficient air release without complex additional components.

Inventive Principle:
Principle #10Preliminary action
