Summary
This study introduces a flexible thermoelectric device (FTD) for stable, pollution-free temperature monitoring of coal gangue mountains, preventing spontaneous combustion without harming vegetation.
Area of Science:
- Materials Science
- Environmental Engineering
- Energy Harvesting
Background:
- Coal gangue mountains pose spontaneous combustion risks.
- Existing temperature monitoring systems are inadequate, causing pollution and harming vegetation.
Purpose of the Study:
- To develop a stable, pollution-free temperature monitoring system for coal gangue mountains.
- To enhance thermoelectric power generation efficiency for effective monitoring.
Main Methods:
- Proposed a flexible thermoelectric device (FTD) using a protrusion-structured liquid metal elastomer (LME).
- Utilized high-thermal-conductivity LME for adherence to gravity heat pipes (GHP) and low-thermal-conductivity elastomer to concentrate heat.
- Investigated the influence of protrusion structure parameters on GHP efficiency.
Main Results:
- The FTD demonstrated effective adherence and heat concentration capabilities.
- Optimized protrusion structure parameters improved thermoelectric power generation efficiency.
- Successful practical application of FTD on GHP was achieved.
Conclusions:
- The developed FTD offers a viable solution for stable, eco-friendly temperature monitoring of coal gangue mountains.
- This technology can prevent spontaneous combustion while supporting vegetation growth.
- The study highlights the potential of LME-based thermoelectric devices for environmental monitoring and energy harvesting.
