Solution Overview
Problem
Existing mass spectrometers and ion mobility spectrometers face challenges in efficiently maintaining a heated ion block at a constant temperature while minimizing heat transfer to other components, leading to increased power consumption and potential functional issues.
Innovation Solution
A polymer interface block is used between the ion block and the vacuum housing, which includes conduits for ion and gas transmission, providing thermal insulation and electrical isolation, thereby containing heat within the source region and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If electrical heaters are used to maintain the ion block at constant temperature, then the ion block temperature is stabilized, but heat transfer to the vacuum housing increases power consumption
Solution Approach 1:
A polymer interface block is introduced as an intermediary component between the heated ion block and the vacuum housing. This polymer material acts as a thermal barrier that mediates the heat transfer path, allowing mechanical support and electrical connection while blocking excessive thermal conduction to the vacuum housing, thereby reducing power consumption.
Solution Approach 2:
The interface block is segmented into distinct functional regions: an axial conduit for ion transmission, gas conduits for transmitting gas to the ion block, and thermal insulation regions. This segmentation allows each region to perform its specific function while collectively managing heat transfer and maintaining temperature stability.
2Productivity
If the ion block is heated to maintain temperature, then desolvation efficiency is improved, but heat transfer to other components causes functional problems
Solution Approach 1:
The polymer interface block serves as a thermal mediator that protects the vacuum housing and analyser from excessive heat. The polymer material's low thermal conductivity allows it to block harmful heat transfer while still permitting mechanical support and electrical signal transmission, thus protecting downstream components from thermal damage.
Solution Approach 2:
The interface block exhibits local quality differentiation where different regions have different thermal properties. The axial conduit region allows ion passage while the surrounding polymer regions provide thermal insulation. This localized functional differentiation enables heat containment in the source region while maintaining structural integrity.
3Strength
If conventional materials are used for the interface block, then mechanical strength is adequate, but thermal insulation performance is insufficient
Solution Approach 1:
The interface block is constructed from polymer composite materials that combine mechanical strength with superior thermal insulation properties. These composite materials provide both the structural support needed to hold the ion block and the vacuum housing, and the thermal barrier properties needed to reduce heat transfer to the vacuum housing.
