AI Technical Summary
In existing technologies, the outer shell of the insulation module deforms at high temperatures, causing internal stress that cannot be released, which can easily damage the weld between the insulation module and the inner shell, posing a safety hazard.
The design employs thermal insulation fixed wall panels and thermal insulation modules. Through flexible plug-in connection between the outer shell and the thermal insulation fixed body, and by utilizing structures such as deformation grooves and limiting rings, thermal stress can be flexibly released. Furthermore, the smoothness of installation and structural strength are improved through guiding slopes and deformation reinforcements.
It effectively releases thermal stress on the outer casing, reduces the risk of damage at the weld joints, improves the service life and safety of the electric heater, and maintains the purity of the airflow.
