Stocker Thermal Insulation for Heat Transfer Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stockers in semiconductor manufacturing facilities face challenges in effectively blocking heat transfer from control panels to storage areas, leading to potential temperature increases that can influence stored containers and their contents.
Innovation Solution
The implementation of a stocker design featuring a wall with a first thermal insulation layer on the control panel storage side and a second thermal insulation layer on the storage area side, along with fans to manage airflow and release heat outside the system, effectively blocking heat transfer and reducing temperature rises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a single thermal insulation layer is arranged on the storage area side of the control panel storage, then heat transfer through the boundary portion is blocked, but heat may still be transferred to the storage area from parts other than the boundary portion
Solution Approach 1:
The thermal insulation structure is divided into two separate layers: a first thermal insulation layer on the wall side of the control panel storage and a second thermal insulation layer on the storage area side. This segmentation allows each layer to independently block heat transfer from different directions, ensuring comprehensive heat protection that a single layer cannot achieve.
Solution Approach 2:
The first thermal insulation layer acts as an intermediary between the control panel storage and the wall, blocking heat transfer from the wall side. The second thermal insulation layer acts as an intermediary between the control panel storage and the storage area, blocking heat transfer to the storage area. Together, they form a complete thermal barrier system.
2Device complexity
If the control panel storage is positioned on the inner side of the wall laterally to the storage area, then the control panel can be housed within the stocker structure, but heat generated in the control panel may still influence the container stored in the storage area
Solution Approach 1:
The stocker is divided into functionally independent zones: a control panel storage area for housing control panels and a storage area for containers. This spatial segmentation, combined with thermal insulation layers, allows the control panel to be integrated into the stocker structure while preventing its heat from affecting stored articles.
Solution Approach 2:
The control panel storage is extracted as a separate functional unit from the main storage area, positioned on the inner side of the wall laterally adjacent to the storage area. This extraction allows independent thermal management of the control panel, enabling heat blocking measures to be applied specifically to protect the storage area without interfering with control panel operation.
