Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In refrigerant units with multiple heat exchangers serving different functions, thermal interference between these exchangers complicates the ability to meet desired temperature requirements for temperature adjustment targets.
Innovation Solution
A refrigerant unit design where a first heat exchanger is positioned between a plurality of second heat exchangers, with the distance from one side of the second exchangers to the first exchanger being greater than the distance from the other side, reducing thermal interference and allowing for independent temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If heat exchangers having different functions are disposed adjacent to each other to shorten channel length, then the refrigerant unit becomes more compact, but thermal interference occurs between heat exchangers making it difficult to respond to desired temperature requirements
Solution Approach 1:
The patent applies asymmetry by intentionally creating unequal distances from the first heat exchanger to the second heat exchangers on opposite sides. Specifically, the distance on one side is made greater than the distance on the other side, which asymmetrically distributes thermal interference effects and allows optimization of temperature control for different heat exchangers while maintaining compact overall design
2Productivity
If heat exchangers are arranged to minimize channel length, then refrigerant flow efficiency improves, but thermal coupling between heat exchangers increases reducing temperature control precision
Solution Approach 1:
The patent applies local quality by creating different spatial relationships between heat exchangers at different locations. The unequal distances from the first heat exchanger to the second heat exchangers on opposite sides create localized thermal environments that can be optimized for specific temperature control requirements, allowing different regions of the refrigerant unit to have different thermal characteristics
