Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If radiating fins and flat tubes are soldered together to form a water-cooling radiator device, then the structural connection is achieved, but thermal impedance increases and heat conduction efficiency decreases
Solution Approach 1:
The patent merges the radiating fin and flat tube into a single integrated component formed from a single sheet body. The flat tube portion and radiating fin portion are created as one continuous piece through folding and forming operations, eliminating the soldered joint entirely. This integration removes the thermal impedance interface while maintaining structural connection, directly resolving the contradiction between structural integrity and heat conduction efficiency.
Solution Approach 2:
The patent replaces the thermal-mechanical joining method (soldering) with a purely mechanical forming process. The single sheet body is folded and formed to create both the flat tube and radiating fin structures, substituting the thermal field soldering process with a mechanical forming process that preserves thermal continuity.
2Ease of manufacture
If soldering is used to connect radiating fins, flat tubes, and water tanks, then the components are joined together, but manufacturing complexity and cost increase
Solution Approach 1:
The patent combines multiple separate components (flat tubes, radiating fins, and connection structures) into a single integrated sheet body structure. This reduces the number of assembly steps from multiple soldering operations to a single forming process, significantly simplifying manufacturing while improving ease of assembly.
Solution Approach 2:
The patent changes the manufacturing parameter from thermal processing (soldering temperature and time) to mechanical processing (forming force and geometry). This parameter transformation eliminates the need for controlled thermal environments, skilled soldering operations, and complex quality control, thereby reducing manufacturing complexity.
3Ease of manufacture
If molten filling material is used during soldering, then components are connected, but fluid outlets and inlets become blocked
Solution Approach 1:
The patent replaces the thermal-melting process with a cold-forming mechanical process. The sheet body is folded and formed at ambient temperature to create the flat tube and radiating fin structures, eliminating molten filling material entirely. This substitution prevents blockage of fluid outlets and inlets while achieving secure component connection through geometric interlocking.
Solution Approach 2:
The patent extracts and eliminates the harmful element (molten filling material) from the manufacturing process. By removing the soldering step entirely and using a forming process instead, the source of blockage is eliminated, thereby improving manufacturing precision regarding fluid outlet positioning.
4Reliability
If radiating fins are soldered to flat tubes, then heat transfer is enabled, but structural strength at the connection point decreases
Solution Approach 1:
The patent merges the radiating fin and flat tube into a continuous single sheet body structure. This integration eliminates the weak soldered joint and creates a uniform structural strength throughout the entire component, while maintaining effective heat transfer through the continuous metal path from the tube to the fin.
