High-Pressure Tank Heating via Vertical Gas Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing high-pressure tank producing apparatuses require longer times for heat treatment due to decreased heat transfer rates, particularly at the lower portions of the tank body, as high-temperature gas does not efficiently flow and stagnate, leading to slower resin curing.
Innovation Solution
The apparatus positions the exhaust port opposite to the injection port across the tank body, allowing high-temperature gas to flow along the surface from the injection to the exhaust port side, enhancing heat transfer and reducing stagnation, with optimized port configurations and distances to increase gas velocity and coverage, thereby increasing the average heat transfer rate across the tank body's surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the gas blowing portion injects high-temperature gas onto the tank container from above, then the upper portion of the tank container is heated, but the lower portion receives insufficient heat due to gas flow direction
Solution Approach 1:
The exhaust port is positioned at the upper portion and the injection port at the lower portion, inverting the conventional arrangement. This causes hot gas to flow from bottom to top through the tank container, ensuring the lower portion receives adequate heat while maintaining efficient gas flow without stagnation.
Solution Approach 2:
The invention introduces vertical flow direction through strategic port positioning, creating a three-dimensional heat distribution pattern. The injection port at the lower portion and exhaust port at the upper portion establish a vertical convection current that penetrates the entire tank container height, improving heat coverage in previously underserved lower regions.
2Ease of manufacture
If the exhaust duct is disposed above the tank container in the gas injecting direction, then gas discharge is simplified, but heat transfer rate decreases due to gas flow stagnation
Solution Approach 1:
The exhaust port is inverted to the upper portion while the injection port is placed at the lower portion. This reversal creates continuous gas flow from bottom to top, preventing stagnation and maintaining high heat transfer rates throughout the treatment process.
Solution Approach 2:
The strategic positioning of injection and exhaust ports creates continuous convective flow through the tank container. Hot gas continuously circulates from the lower injection port through the tank body to the upper exhaust port, ensuring sustained heat transfer without stagnation or dead zones.
3Speed
If gas flows directly from injection port to exhaust port without contacting tank body, then gas flow velocity is high, but heat transfer efficiency decreases
Solution Approach 1:
The injection port is positioned at the lower portion to create localized high-velocity jet flow that impinges on the lower tank surface. This localized energy concentration ensures efficient heat transfer at the injection zone while maintaining overall flow velocity throughout the system.
Solution Approach 2:
The vertical arrangement of injection and exhaust ports creates multi-dimensional heat distribution. Gas flows vertically through the tank container height, ensuring heat is delivered to all regions including previously underserved lower portions, while maintaining flow velocity through the pressure gradient.

AI summary
A high-pressure tank producing apparatus capable of reducing time for increasing temperature of a tank body. The apparatus that heats the tank body with fibers impregnated with a thermosetting resin wound around its surface includes a heating chamber for housing the tank body and a retaining mechanism for retaining the tank body within the heating chamber, in which the heating chamber has an injection port for injecting heated gas onto the surface of the tank body and an exhaust port for discharging the gas to the outside of the heating chamber, the exhaust port being disposed in a position where the injection port is projected in a gas injecting direction, and the retaining mechanism retains the tank body in a region where the injection and exhaust ports overlap with each other as viewed from the gas injecting direction and in a position between the injection and exhaust ports.
