Bent Pipe with Retention Member to Maintain Bending Angle Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bent pipes used in semiconductor refrigerators are prone to deformation under external forces during manufacture, transportation, and installation, affecting the consistency of the bending angle and the refrigerant flow, which is critical for effective heat exchange.
Innovation Solution
A bent pipe design with retention members of high elastic modulus, such as carbon steel or alloy steel, is implemented to maintain the constant bending angle and increase rigidity by being successively fixed to the bent portions, ensuring reliable refrigerant flow and phase-change heat exchange.

Engineering Contradiction Analysis
1Ease of operation
If the bent pipe is subjected to external forces during manufacture, transportation and installation, then the pipe may be easier to handle and install, but the bent portions deform and the bending angle changes
Solution Approach 1:
Retention members are pre-installed on the bent pipe at specific locations along the bent portions. These retention members are prepared in advance to prevent deformation during subsequent handling, transportation, and installation processes, thereby maintaining the bending angle precision while allowing ease of operation.
Solution Approach 2:
Retention members are selectively installed only at the bent portions of the pipe where deformation is most likely to occur, rather than along the entire length of the pipe. This localized approach provides precise protection where needed while maintaining ease of handling in other areas.
2Strength
If retention members are added to the bent pipe, then the rigidity and bending angle stability are improved, but the device complexity increases
Solution Approach 1:
Retention members are installed only at the bent portions of the pipe where additional support is needed to maintain rigidity and prevent deformation. The straight sections of the pipe remain unprotected, maintaining simplicity. This localized approach increases strength where necessary without unnecessarily complicating the entire structure.
Solution Approach 2:
Instead of providing continuous support along the entire length of the bent pipe, retention members are installed at specific critical locations along the bent portions. This partial action provides sufficient rigidity and deformation prevention while avoiding the excessive complexity of complete coverage.

AI summary
A bent pipe and a semiconductor refrigerator having the same are provided. The bent pipe for a fluid to flow therein includes a plurality of bent portions; a plurality of connecting pipe sections, each connecting two adjacent bent portions; and a retention member, which is successively fixed at different locations along the length thereof to the bent portions on the same side of the bent pipe. At least some of the pipe sections of the bent pipe can be kept in the bent shape by a retention member.
