Intumescent Fire Wrap with Ventilation Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire-protection solutions, such as mineral wool, are not suitable for locations requiring minimal dust and fiber presence, like clean rooms or telecommunication systems, as they tend to form dust and contain fibers, and fail to effectively manage heat through air circulation.
Innovation Solution
A fire-protection element comprising a mat of intumescent material with ventilation holes and a reinforcing inlay, which stabilizes the intumescent crust and facilitates air circulation to remove heat, is designed to be flexible and fiber-free, allowing for easy adaptation to various surfaces and efficient heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mineral wool is used for fire-protection wraps, then fire protection is provided, but dust and fiber formation occurs making it unsuitable for clean rooms and telecommunication systems
Solution Approach 1:
The patent uses a porous fire-protection material with controlled pore structure that provides fire protection while preventing dust and fiber formation. The porous structure allows air circulation for cooling while maintaining material integrity and not shedding particles, making it suitable for clean room and telecommunication applications.
Solution Approach 2:
The invention employs a composite material structure combining fire-retardant properties with low dust/fiber generation characteristics. The composite nature allows simultaneous achievement of fire protection reliability and cleanliness requirements for sensitive environments.
2Reliability
If traditional fire-protection materials are used, then fire sealing is achieved, but heat removal through air circulation is insufficient
Solution Approach 1:
The porous structure of the fire-protection material enables air to circulate through it, facilitating heat removal by convection while maintaining fire sealing integrity. The interconnected pores allow airflow paths that carry heat away from protected components.
Solution Approach 2:
The invention utilizes pneumatic principles by allowing air flow through the material structure. The ventilation holes and porous structure create channels for air circulation, using fluid dynamics to achieve passive cooling of protected elements during fire exposure.
3Adaptability or versatility
If the fire-protection element needs to adapt to various surfaces, then flexibility is required, but structural stability may be compromised
Solution Approach 1:
The fire-protection element is designed as a flexible wrap that can conform to various cable arrangements and surface geometries. The flexible thin-film structure maintains structural integrity while adapting to different shapes, ensuring both adaptability and stability.
