Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature sensor is disposed on the inlet-side or outlet-side of the heat exchanger, then the refrigerant temperature can be detected, but the detection accuracy is insufficient due to lack of direct contact with the refrigerant tube
Solution Approach 1:
A guide tube is introduced as an intermediary component that bridges the temperature sensor and the refrigerant tube. The guide tube is inserted into the refrigerant tube and maintains direct contact, allowing the temperature sensor to accurately detect refrigerant temperature through the guide tube without requiring direct mounting on the refrigerant tube itself.
Solution Approach 2:
The temperature sensor is extracted from direct contact with the refrigerant tube and positioned separately on the inlet-side or outlet-side of the heat exchanger. The guide tube serves as a延伸 component that transfers the temperature information from the refrigerant tube to the sensor, simplifying the sensor mounting while maintaining detection accuracy.
2Reliability
If the guide tube and temperature sensor are not firmly fixed in contact, then the structure is simpler, but the temperature detection becomes unstable and inaccurate
Solution Approach 1:
The fixing device is segmented into two distinct support units: a tube support unit that secures the guide tube and a sensor support unit that secures the temperature sensor. This segmentation allows each unit to be optimized for its specific function while maintaining the contact relationship between the guide tube and sensor through the connecting structure.
Solution Approach 2:
The fixing device is designed to pre-establish and maintain firm contact between the guide tube and temperature sensor before operation begins. The tube support unit and sensor support unit are configured to ensure continuous, stable contact, preventing any separation or movement that could compromise temperature detection reliability during heat exchanger operation.
