Description

technical field [0001] The invention relates to the technical field of centrifugal heat exchangers, in particular to a novel integrated high-efficiency phase-change centrifugal heat exchanger. Background technique [0002] At present, compared with traditional heat dissipation devices, air bearing heat exchangers and vapor chambers are two emerging heat dissipation structures, and the heat dissipation effect has been significantly improved. The air bearing heat exchanger is a brand-new air-cooled heat exchanger. The heat exchanger is composed of a brushless motor, a static plate fixed on the bottom plate, a fin and a moving plate composed of a fin base plate. There is an air gap of about 30 μm; the heat load is loaded on the static disk, and the heat on the static disk is transferred to the fins of the moving disk. The traditional stationary fins rotate at high speed under the drive of the motor, and the heat is carried by the air through centrifugal motion. Pass it on qu...
