Solution Overview
Problem
Radiant heaters with transparent glass tubes face issues of overheating and potential melting due to high flame temperatures, limiting the effective heating output and visibility of flames, which affects both heating efficiency and aesthetic appeal.
Innovation Solution
Incorporating an opaque flame bundle tube made of metal or ceramics within the glass tube to contain and radiate heat, while allowing visible flames through openings, ensuring the glass tube remains cooler and stable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If flames are allowed to reach high into the radiating unit for maximum heating effect, then heat output is improved, but the glass tube becomes too hot and may soften or melt
Solution Approach 1:
The patent implements a nested structure where an inner flame bundle tube is placed inside the outer glass tube. The inner tube contains the hottest flame region while the outer glass tube remains at lower temperatures. This nested arrangement allows the flames to reach high for maximum heating effect while the glass tube is protected from direct exposure to extreme temperatures, preventing softening or melting.
Solution Approach 2:
The inner flame bundle tube acts as an intermediary element between the flames and the outer glass tube. It mediates the thermal interaction by containing the high-temperature flame region and transferring heat to the outer tube in a controlled manner, preventing direct contact between the hottest flames and the glass tube that could cause damage.
2Stability of the object's composition
If an opaque flame bundle tube is used to contain high temperatures, then glass tube stability is improved, but flame visibility is reduced
Solution Approach 1:
The inner flame bundle tube is designed to glow with characteristic colors (yellow-orange) at high temperatures, creating a visually appealing effect. This color change at high temperature serves both functional purposes (indicating temperature containment) and aesthetic purposes (providing pleasant visual effect), partially compensating for the reduced visibility through the opaque material.
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 enhances heat radiation and maintains the glass tube's stability, achieving higher heat output and a pleasant visual effect by containing high flame temperatures within the opaque tube, which glows and radiates heat more effectively than transparent tubes.
Implementation Method 1
the flame bundle tube comprises an opaque flame bundle tube... through which combustion gases resulting from the combustion are led... containing high flame temperatures within the opaque tube, which glows and radiates heat more effectively
Implementation Method 2
The space between the glass tubes can be flushed with water so that the glass tubes are cooled... the flame bundle tube... ensures the glass tube remains cooler and stable
