Title:
PHOTO-THERMAL MULTIPLEXING APPARATUS BASED ON SUB-BAND REVERSE DIFFERENTIAL OPTICAL PATH
Document Type and Number:
WIPO Patent Application WO/2023/020449
Kind Code:
A1
Abstract:
The present application provides a photo-thermal multiplexing apparatus based on a sub-band reverse differential optical path. The apparatus comprises, but is not limited to: a sub-band reverse differential optical path element, a mid-infrared radiative cooling device, and a sunlight converter. The sub-band reverse differential optical path element is disposed above the mid-infrared radiative cooling device and the sunlight converter, suspended by means of a support so as to avoid generating heat conduction due to contact between the sub-band reverse differential optical path element and a component under it. A cavity is provided between the mid-infrared radiative cooling device and the sunlight converter below. The cavity is provided to prevent thermal conduction between the two. Such a design achieves simultaneous and efficient utilization of a solar heat source and a cold source for radiative cooling.
