The insulating materials divide the inner from the outer surface.
As the assumption that heat transfer limit of heat pipe is not considered, the boundary condition of inner of heat pipe can be set to dummy materials except considering the materials attributes of heat pipe.

Purely as a hinge, it will waste material.At the same time,the end-plate of the original flexural capacity can not play ,and even affect the structure moment distribution.
All material stress-strain relationship uses an ideal elastic-plastic model to express. yield criterion uses Von Mises.
The remaining material yield strength:235 Mpa, E=2×105Mpa.

In order to know the influence of heat exchange efficiency under different channel shapes, structures and materials, the test piece is designed to be replaceable.
The material of shell as well as inlet and outlet ports is selected PP-R which has good toughness and intension.
So in order to meet the research requirements, just switching to a different experimental test piece, we can go on studying heat exchangers with different structures and materials.
