摘要:	This paper describes the development of triangular grooved MHP, star grooved MHP and rhombus grooved MHP their fabrication and testing. The heat transfer performance of micro heat pipe was enhanced due to the better capillarity provided by more acute angles and micro gaps. Triangular grooved MHP, Star grooved MHP and rhombus grooved MHP were fabricated by bulk micro machining on 4-inch (100) silicon wafers. Finally, triangular grooved MHP structure was bonded by employing anodic bonding technique. Star grooved MHP and rhombus grooved MHP structure was bonded by employing an eutectic bonding technique. Testing was conducted to evaluate the performance over a range of working fluid volume and heat fluxes. A heater was glued on the evaporator section of the heat pipe, cold water was poured through a copper pipe in the condenser section, and K-type thermocouples were pasted on the micro heat pipe in the direction of the length. Then the thermocouples were joined to a data acquisition system and Fourier’s Law was used to calculate the effective thermal conductivity. The best thermal conductivities of triangular grooved MHP, star grooved MHP and rhombus grooved MHP are 208 W/mK, 277.9 W/mK and 289.4 W/mK, respectively.
