Title:
HEATPIPE PROVIDED WITH PHOTONIC CRYSTAL, HEAT TRANSFER APPARATUS AND DATA PROCESSING SYSTEM
Document Type and Number:
Japanese Patent JP3639575
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus for transporting and ejecting heat energy.
SOLUTION: A heat transporter includes a photonic microheatpipe and a source of photons. The photonic microheatpipe is a photonic crystal that shows pronounced Raman effect and is thermally coupled to a heat source. When a photon scatters back from phonons (lattice vibrations) in the crystal, the properties of the reflected spectrum are governed by the Raman effect. According to the present invention, the photonic crystal is selected such that the Stokes lines are suppressed while the anti-Stokes lines are not attenuated. Hence the photons reflected from the photonic crystal have frequencies (and energy) greater than the incident photons. Thus, heat energy represented as acoustic phonons is transferred into photons. The photons corresponding to the anti-Stokes lines are transmitted through the photonic microheatpipe away from the heat source to a suitable point for rejecting the heat energy.
