Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermodynamic systems for producing heat by compressing a fluid struggle to increase the temperature of the fluid upstream of a heat exchanger without altering the setpoint pressure, leading to inefficiencies and potential pressure changes due to geometric transformations in the channel structure.
Innovation Solution
The system organizes the channel conveying the compressed fluid into a plurality of elementary channels with specific geometric configurations, including inlet and outlet chambers designed to maintain pressure and flow rate, utilizing a combination of flare and Venturi effect principles to minimize pressure changes and enhance heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the channel is transformed from a single pipe to a plurality of elementary channels, then the heat transfer efficiency is improved, but the pressure stability deteriorates due to geometric structural changes
Solution Approach 1:
The single channel is divided into multiple elementary channels arranged in parallel, increasing the surface area for heat transfer while maintaining fluid flow characteristics. This segmentation allows heat to be transferred more efficiently across multiple smaller pathways rather than one large channel.
Solution Approach 2:
The elementary channels are arranged concentrically with an inner channel and an outer channel, creating a nested structure where the inner channel is surrounded by the outer channel. This nested arrangement maximizes heat transfer surface area while maintaining compact geometry and pressure stability.
2Temperature
If the channel geometry is modified to increase heat transfer, then the temperature increase is improved, but the pressure change becomes harmful
Solution Approach 1:
Different sections of the channel system have different geometric properties optimized for their specific functions. The elementary channels have smaller diameters optimized for heat transfer, while the inlet and outlet chambers have larger dimensions optimized for maintaining pressure stability and reducing flow resistance.
Solution Approach 2:
Inlet and outlet chambers are introduced as intermediary structures between the single inlet/outlet pipes and the multiple elementary channels. These chambers act as buffers that distribute incoming flow evenly to all elementary channels and collect outflow, preventing pressure fluctuations that would occur with direct connection.
3Quantity of substance
If the cumulative sections of elementary channels match the main section, then the flow rate is maintained, but the pressure control becomes difficult due to transition zones
Solution Approach 1:
Inlet and outlet chambers serve as intermediary structures that facilitate smooth transitions between the single main channel and multiple elementary channels. These chambers reduce flow resistance at transition zones by providing gradual area changes rather than abrupt expansions or contractions, thereby maintaining pressure control.
Solution Approach 2:
The inlet chamber is designed with a flare that dynamically adapts the flow distribution to the multiple elementary channels. The flared geometry gradually expands the flow area, allowing smooth distribution of fluid into the parallel channels while maintaining velocity and pressure characteristics.
