Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-chamber heat treatment devices experience a decrease in cooling performance when transitioning from mist cooling to gas cooling, as the cooling efficiency of gas cooling systems is inferior to mist cooling systems.
Innovation Solution
A multi-chamber heat treatment device is designed with a gas cooling chamber adjacent to an intermediate transport chamber, featuring a cooling gas circulation device with a gas inlet and outlet positioned to blow and exhaust cooling gas directly onto the treatment object, enhancing cooling efficiency by minimizing gas dispersion and maximizing gas usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gas cooling system is used instead of a mist cooling system, then the device complexity is reduced and ease of operation is improved, but the cooling efficiency deteriorates
Solution Approach 1:
The gas inlet and gas outlet are positioned at specific locations within the cooling chamber to create localized high-velocity gas flow zones. The gas inlet is arranged to blow cooling gas directly onto the treatment object, while the gas outlet is positioned to exhaust used gas efficiently, creating localized quality differences in gas flow distribution to maximize cooling efficiency
Solution Approach 2:
The gas cooling system transitions from a conventional single-direction gas flow to a bidirectional flow system where cooling gas is blown from the gas inlet onto the treatment object and exhausted from the gas outlet. This dimensional change in gas flow direction creates a circulation pattern that improves cooling efficiency by ensuring continuous fresh cooling gas contact with the treatment object
2Loss of energy
If cooling gas is blown directly onto the treatment object, then the cooling efficiency is improved, but the gas consumption increases
Solution Approach 1:
The cooling gas circulation system creates a feedback loop where used cooling gas is exhausted from the gas outlet and potentially recirculated or replaced by fresh cooling gas from the gas inlet. This feedback mechanism ensures that the cooling gas flow is continuously optimized to maintain high cooling efficiency while minimizing excessive gas consumption
Solution Approach 2:
The system discards used cooling gas through the gas outlet while maintaining a controlled supply of fresh cooling gas through the gas inlet. By strategically positioning the gas outlet to exhaust used gas efficiently, the system recovers the cooling effect by continuously introducing fresh cooling gas, thereby reducing overall gas consumption while maintaining high cooling efficiency
