Solution Overview
Problem
Existing devices for temperature-controlled fluid flows used in shrink packaging face issues with inhomogeneous heat distribution and high flow resistance when mixing combustion gases with cold air, affecting the quality and consistency of packaging material shrinkage.
Innovation Solution
A device and method that combine a fluid flow with a hot gas volume flow using a feed device with multiple openings at different vertical levels, allowing for a homogeneous temperature control by passing the hot gas volume flow through a channel with a widening section and oriented hollow bodies to ensure efficient heat exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If combustion gases are mixed with cold air flow in prior art devices, then temperature control is achieved, but inhomogeneous heat distribution and high flow resistance occur
Solution Approach 1:
The feed device is divided into multiple hollow bodies arranged in rows, each with multiple openings. This segmentation allows the hot gas volume flow to be distributed across numerous small openings rather than a single large opening, creating multiple discrete heat sources in the fluid flow. The result is a more uniform temperature distribution throughout the packaged goods, eliminating the inhomogeneous heating problem of prior art devices.
Solution Approach 2:
The openings in the hollow bodies are strategically positioned at different vertical levels and orientations to deliver hot gas to specific locations within the packaged goods. This local quality approach ensures that heat is delivered precisely where needed, achieving uniform temperature control across the entire product assembly rather than creating hot or cold spots.
2Temperature
If combustion gases are mixed with cold air flow in prior art devices, then temperature control is achieved, but flow resistance increases
Solution Approach 1:
The device utilizes pneumatic principles by introducing the hot gas volume flow through multiple small openings in hollow bodies rather than forcing it through a narrow mixing channel. This approach dramatically reduces flow resistance, as the gas can escape through numerous pathways simultaneously, eliminating the high pressure drop and flow resistance problems associated with traditional mixing devices.
3Temperature
If combustion gases are mixed with cold air flow in prior art devices, then temperature control is achieved, but burner performance is degraded
Solution Approach 1:
The invention extracts the mixing function from the burner system entirely. Instead of mixing combustion gases with cold air in a channel (which interferes with burner operation), the hot gas is delivered separately through the feed device hollow bodies. This separation eliminates the negative interaction between the mixing process and burner performance, allowing the burner to operate at full efficiency while still achieving temperature control through the distributed opening system.
