| Abstract |
This study evaluated the thermal management and CO2 capture performance of LED heatsinks coated with multi-walled carbon nanotubes (MWCNT) and polyethyleneimine (PEI), demonstrating their potential for enhancing heatsink efficiency. By combining MWCNT, a physical adsorbent, with PEI, a chemical adsorbent, a porous material was created and applied to the heatsink surfaces. The heatsink containing 16 wt% MWCNT showed a maximum temperature 9.99% lower than that of an uncoated heatsink, indicating improved thermal management capabilities. The endothermic effect during CO2 desorption significantly mitigated temperature increases, further enhancing the cooling effect. The heatsink with 12 wt% MWCNT-PEI achieved the highest CO2 capture capacity at 4.25 mmol g?¹. This material effectively utilized heat from the LEDs to promote CO2 desorption, reducing heat generation from the LEDs. The released CO2 can be applied in areas such as indoor agriculture to optimize plant growth. These findings underscore the potential for integrating LED heatsink technology with CO2 capture systems to enhance environmental sustainability and energy efficiency. |
