Abstract

In recent years, with the development of miniaturization and high-power electronic devices,

electronic cooling devices have become increasingly important. The concept of Micro Heat
Pipe (MHP) was first proposed in 1984 in the context of electronic cooling applications.
MHPs are known for their small size and high heat transfer efficiency, which provides an

adaptable solution for applications with limited weight and space. Since then, many theories
and experimental tests have been proposed to validate and improve the thermal efficiency of
micro heat pipes(Hung,2011). In this study, we investigated the improvement of the cooling
efficiency of the basic micro heat pipe through practical experiments, and studied the effect of
the channel geometry on the cooling efficiency and its principle through literature collection.

The results show that the basic miniature heat pipe has been able to bring up to 21.5%
efficiency improvement; and among the different polygonal channels, the star groove channel
has the highest heat dissipation efficiency.
