Immersion Heater Flame Path for Pressurized Gas Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersion heaters lack effective mechanisms to safely manage pressurized gases generated when combustible vapors or gases come into contact with heating elements, potentially leading to unsafe conditions and inefficiencies in heat transfer.
Innovation Solution
The design incorporates a flame path or exhaust path between the heating element and surrounding components, which allows pressurized gases to escape along a predetermined path, featuring a tortuous configuration to control the exhaust and prevent re-ignition, ensuring safe venting and efficient heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a heating element is placed in a tube to heat substances, then heating efficiency is improved, but pressurized combustible gases may accumulate and create safety hazards
Solution Approach 1:
The patent extracts the harmful pressurized combustible gases from the heating system by providing a dedicated exhaust path that leads away from the heating element and tube assembly. The exhaust path includes an outlet positioned away from the heating element that allows these gases to escape safely without accumulating in the heating zone, thus resolving the safety hazard while maintaining heating efficiency.
Solution Approach 2:
The patent introduces an intermediary exhaust path and outlet structure that mediates between the heating element and the surrounding environment. This intermediary pathway allows pressurized combustible gases to be transported away from the heating element through a controlled route, preventing direct accumulation near the heat source while maintaining the integrity of the heating function.
2Temperature
If the heating element is enclosed in a tube, then heat transfer to the substance is improved, but pressurized gases have no safe escape path
Solution Approach 1:
The patent segments the enclosed heating system into distinct functional zones: a heating zone where the heating element is enclosed in the tube for efficient heat transfer, and an exhaust zone with a separate exhaust path and outlet that provides a dedicated escape route for pressurized gases. This segmentation allows the tube to maintain its heat transfer function while the separate exhaust pathway ensures safety by providing a designated escape route for gases.
Solution Approach 2:
The patent extends the system into another spatial dimension by adding an exhaust path that leads away from the tube assembly in a different direction. The outlet is positioned away from the heating element and extends in a direction that provides a three-dimensional escape path for pressurized gases, allowing them to leave the enclosed heating zone without compromising the heat transfer efficiency within the tube.
3Device complexity
If no exhaust path is provided, then the heating unit structure is simpler, but combustible vapors may ignite and create unsafe conditions
Solution Approach 1:
The patent converts the potentially harmful ignition of combustible vapors into a beneficial controlled exhaust process. By providing an exhaust path with an outlet positioned away from the heating element, the system allows combustible vapors to escape and be safely vented rather than accumulating and igniting. The exhaust path transforms what would be a dangerous situation into a controlled and safe operation.
4Length of moving object
If the outlet is positioned close to the heating element, then the exhaust path is shorter, but igniting combustible vapors may heat surrounding components
Solution Approach 1:
The patent applies preliminary anti-action by positioning the outlet away from the heating element before any ignition of combustible vapors can occur. This preemptive positioning ensures that even if vapors ignite in the exhaust path, the flame cannot reach back to heat the heating element or surrounding components. The spatial separation acts as a preventive measure against thermal feedback to the heating system.
