Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional turbomolecular pumps require separate cooling mechanisms for the main unit and control device, leading to increased complexity, labor, and reduced cooling efficiency due to separate panels and integration challenges, which hinder cost reduction and simplify operations.
Innovation Solution
Integration of the turbomolecular pump main unit and control device with a cooling mechanism that serves as a single panel, allowing the cooling mechanism to directly contact and cool both units, reducing the number of components and enabling independent assembly of the turbomolecular pump main unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the turbomolecular pump main unit and control device are structured separately with separate cooling mechanisms, then each unit can be cooled independently, but the device complexity increases and requires more components
Solution Approach 1:
The patent merges the cooling mechanism with the control device case, making the control device case itself serve as the cooling mechanism housing. This integration eliminates the need for a separate cooling mechanism structure, reducing device complexity while maintaining the cooling function through direct thermal contact between the turbomolecular pump main unit and the control device case.
2Device complexity
If the cooling mechanism is integrated with the control device, then the number of components is reduced, but two panels are required at the contact surface increasing complexity
Solution Approach 1:
The control device case is designed to serve multiple functions simultaneously: it houses the control device components and acts as the cooling mechanism housing. This multi-functionality eliminates the need for separate panels at the contact surface, as the case itself provides both structural and cooling functions, simplifying manufacturing.
3Ease of operation
If the turbomolecular pump main unit requires periodic overhaul, then maintenance is necessary, but integration with control device increases disassembly work
Solution Approach 1:
The patent designs the integrated structure with separable connections between the turbomolecular pump main unit and the control device case. This segmentation allows the turbomolecular pump main unit to be removed for overhaul without damaging the control device case, reducing disassembly complexity while maintaining integration benefits during normal operation.
4Device complexity
If cooling is performed through the control device case rather than direct component contact, then structural simplicity is achieved, but cooling efficiency decreases
Solution Approach 1:
The control device case acts as an intermediary thermal conductor between the turbomolecular pump main unit and the external environment. The case is designed with appropriate thermal conductivity and heat dissipation structures to efficiently transfer heat from the pump unit while maintaining structural simplicity, balancing cooling efficiency with design simplicity.

AI summary
The provision of the components requiring cooling on top of the cooling mechanism enables the cooling efficiency to be increased. Furthermore, a case of a control device is attached to the cooling mechanism whereon the components requiring cooling are disposed. The cooling mechanism fulfills the role of the contact surface of the case of the control device with the turbomolecular pump main unit, where the case does not have a case panel on the contact surface with the turbomolecular pump main unit. The cooling mechanism fulfills the role of one surface of the case for the control device, where the cooling mechanism is structured integrally with the control device. Additionally, the turbomolecular pump main unit, the cooling mechanism, and the control device are structured integrally by the turbomolecular pump main unit and the cooling mechanism being in contact.
