The miniaturization of electronics continues to advance, creating a greater need for the development and optimization of heat dissipation equipment. A heat pipe is an essential component in electronic cooling systems. This study analyzed a grooved heat pipe using modeling in ANSYS 22, with aqueous surfactant solutions (SDS and Rhamnolipid) serving as working fluids. The thermal and fluid behavior was examined through graphical representations. The thermal resistance of each fluid was calculated, indicating that SDS and Rhamnolipid have nearly identical values. However, a significant advantage of Rhamnolipid is that it is a bio-surfactant, making it a suitable replacement for SDS, which is a synthetic surfactant.

摘要

The miniaturization of electronics continues to advance, creating a greater need for the development and optimization of heat dissipation equipment. A heat pipe is an essential component in electronic cooling systems. This study analyzed a grooved heat pipe using modeling in ANSYS 22, with aqueous surfactant solutions (SDS and Rhamnolipid) serving as working fluids. The thermal and fluid behavior was examined through graphical representations. The thermal resistance of each fluid was calculated, indicating that SDS and Rhamnolipid have nearly identical values. However, a significant advantage of Rhamnolipid is that it is a bio-surfactant, making it a suitable replacement for SDS, which is a synthetic surfactant.
