Solution Overview
Problem
Current gas heating devices for liquids or viscous fluids suffer from low efficiency and uneven heating due to the geometry of heat exchange tubes lacking control elements, requiring high gas pressure and complex constructions to achieve homogeneous heat distribution.
Innovation Solution
A gas heating device with a simplified construction featuring gas injection nozzles without radial air inlets and deflectors that direct gas flow along the horizontal axis of the heat exchange tube, combined with a deflecting cover for controlled gas exhaustion, allowing efficient and homogeneous heat distribution at lower gas pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If high gas pressure is used to improve thermal efficiency, then combustion efficiency improves, but gas consumption increases and safety risks increase
Solution Approach 1:
The patent changes the gas pressure parameter from high pressure to low pressure operation. The injection nozzles are designed to work efficiently at low pressure, and the deflector geometry is optimized for low-pressure flow patterns, achieving good combustion and heat distribution without requiring high gas pressure input
Solution Approach 2:
The patent introduces local quality variations through the deflector plate geometry and window distribution. The deflector creates localized flow control zones that optimize combustion efficiency at each location, allowing effective heating without uniform high pressure throughout the system
2Manufacturing precision
If complex internal structures are added to heat exchange tubes to control gas flow, then homogeneous heating improves, but device complexity increases
Solution Approach 1:
The patent segments the heat exchange tube into multiple sections with deflectors positioned at different locations along its length. Each deflector segment controls the flow in its local region, creating homogeneous heating through distributed control rather than a single complex internal structure
Solution Approach 2:
The deflector plate acts as an intermediary element between the gas injection nozzle and the heat exchange tube. It mediates the gas flow by directing it along the tube walls and controlling its distribution, achieving flow control without modifying the tube's internal geometry
3Loss of energy
If gas injection nozzles with radial air inlets are used, then combustion efficiency improves, but device complexity and cost increase
Solution Approach 1:
The patent employs self-service combustion where ambient air enters the heat exchange tube naturally through openings and convection currents. The system uses the existing flow dynamics and temperature differences to supply air for combustion without requiring dedicated air inlet structures on the nozzles
Solution Approach 2:
The patent merges the functions of gas injection and air supply into a single simplified nozzle design. The deflector plate and heat exchange tube openings collectively perform the air mixing function that would otherwise require complex radial air inlet structures on each nozzle
4Ease of manufacture
If continuous cross section heat tubes are used, then manufacturing is simple, but homogeneous heat distribution is poor
Solution Approach 1:
The patent maintains the simple continuous cross-section tube design but segments the flow control function by adding external deflector plates at different locations. This keeps the tube itself simple to manufacture while achieving homogeneous heat distribution through the segmented flow control provided by the deflectors
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
The solution provides improved thermal efficiency and homogeneous heating of fluids with a simpler, less costly design that maintains heat within the heat exchange tube, reducing gas consumption and operational complexity.
Implementation Method 1
gas injection nozzles, which are turned and open to the inlet end of the heat exchange tube in order to provide, upon gas burning, flows of combustion gases through the heat exchange tube
Implementation Method 2
the heat, generated by the burning of the gas released by the injection nozzles, passes, with reduced speed through the interior of the heat tubes, which are usually provided submerged in the bath of the fluid to be heated
