Solution Overview
Problem
Existing gas-heated infrared radiation emitters suffer from long warm-up times, instability, and suboptimal performance in terms of infrared radiation emission.
Innovation Solution
A gas-heated infrared radiation emitter with a screen formed by a specific structure comprising through-prisms or through-channels with polygonal bases that are juxtaposed to form a tiling of the main surfaces, allowing for high degrees of opening and efficient gas circulation, and optionally including a central through-opening for improved ignition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional screens (ceramic rods, metal wires, or mesh materials) are used in gas-heated infrared radiation emitters, then the structure provides stability and optimized operation, but the warm-up time is long (several minutes) and operating stability may be unstable with unexpected shutdowns
Solution Approach 1:
The screen is segmented into a modular structure composed of multiple parallel plates with through-prisms, where each plate can be independently manufactured and assembled. This segmentation allows for optimized thermal pathways while maintaining structural integrity, reducing warm-up time without compromising operating stability
Solution Approach 2:
The invention uses composite construction combining multiple plates with through-prisms arranged in parallel, creating a hybrid structure that leverages the advantages of different configurations. This composite approach enables both rapid heating and stable operation by distributing thermal and mechanical loads across multiple elements
2Quantity of substance
If screens with foamed materials or open pores are used, then the structure allows gas circulation, but the infrared radiation performance is below average and warm-up time is extended
Solution Approach 1:
The through-prisms create controlled porous channels that allow gas circulation while maintaining structural integrity. The geometric precision of the through-prisms optimizes both gas flow and thermal radiation pathways, improving infrared radiation efficiency compared to random foam structures
Solution Approach 2:
The invention transitions from two-dimensional mesh or wire screens to three-dimensional through-prism structures with optimized geometric configurations. This dimensional enhancement allows for improved gas circulation patterns and enhanced infrared radiation emission through controlled geometric shapes
3Use of energy by moving object
If mesh materials with geometric unit cells are used, then the screen structure is efficient for infrared radiation, but the operation is unstable with unexpected shutdowns and long warm-up times
Solution Approach 1:
The screen is divided into multiple parallel plates with through-prisms, where each plate acts as an independent radiating element. This segmentation provides multiple parallel thermal pathways, ensuring that if one element fails or cools down, others maintain operation, thereby improving reliability while preserving infrared radiation efficiency
Solution Approach 2:
The invention optimizes geometric parameters of the through-prisms (shape, size, spacing, and arrangement) to achieve the optimal balance between infrared radiation efficiency and thermal stability. By carefully controlling these parameters, the system maintains high radiation efficiency while ensuring stable operation and preventing unexpected shutdowns

AI summary
The disclosure relates to a gas-heated infrared radiation emitter comprising at least one radiating screen, which is for example made of ceramic and/or metal, in the form of at least one plate comprising a lower main surface and an upper main surface that are distant from each other, and a plurality of through-prisms, which are preferably hollow, extending from the lower main surface to the upper main surface, each prism being defined by a polygonal base and by an axis. The prisms may be juxtaposed with one another so that their polygonal bases form a tiling of at least one portion of the lower and upper main surfaces of said plate.
