Abstract
It is well known that the thermal conductivity of a working fluid, such as water or organic solution, can be significantly improved by adding suspended nanoparticles. The fluid with added nanoparticles is termed “nanofluids”. After investigations conducted to study the thermal conductivity of nanofluids in the past five years, the factors for a higher thermal conductivity of nanofluids than that of pure fluids can be attributed to both cluster and diffusion effects of nanoparticles.
In this proposal, the nanofluid will be applied to a novel packaging base for a laser diode. This packaging base is essentially a miniature disk-type heat pipe with radiating microchannels from the center to the peripheral. The added gold nanoparticles with diameter ranging from 3 nm (±2nm) to 80 nm (±10nm) are fabricated in our own laboratory. In the first year, the primary goal is to compare the thermal resistance and maximum heat flux of miniature disk-type heat pipe (DMHP) and traditional heat pipes with and without nanoparticles. If the thermal performance of DMHP and traditional heat pipes can be enhanced significantly by adding nanoparticles into the working fluid, one can foresee the potential market value of nanofluids in the cooling applications of electronic devices.
After a study on the property of nanofluids, this project will proceed to a series studies on the fundamental thermal properties of nanofluids, included the calculated and measured data. This project will research on the effect of pool boiling of nanofluids.
