AI Technical Summary
In existing Stirling refrigeration systems, as the length of the heat exchange tubes increases, the stability and strength of the welded joints decrease, affecting the stability and heat exchange efficiency of the heat exchange tubes.
The design employs an arc-shaped connector for welding the heat exchange tubes. Through the connecting holes and positioning steps within the arc-shaped connector, the heat exchange tubes are stably positioned and sealed. The annular gap accommodates the solder, enhancing the connection strength, and stable flow is achieved through the positioning holes and connecting grooves.
Extending the flow path length of the heat exchange tube increases the heat exchange area and refrigeration efficiency, while maintaining the installation stability and sealing of the heat exchange tube, thereby improving the overall performance of the refrigeration unit.
