1. A transparent solar heat absorbing apparatus comprising:
- a transparent member that allows sunlight to pass through;
a wavelength selective member disposed beneath the transparent member, the wavelength selective member allowing light in a transmission range including at least a visible wavelength range to pass through and reflecting light in a reflection range including at least an infrared wavelength range; and
a heating tank formed between the transparent member and the wavelength selective member, the heating tank being filled with a heating medium,wherein at least one of the transparent member and the wavelength selective member has a waveform structure on at least one of its upper surface and bottom surface;
wherein the transparent member has the waveform structure on at least one of the upper surface and the bottom surface of the transparent member in a first cross sectional view, and a pseudo traveling direction of the waveform structure of the transparent member is a first direction, andwherein the wavelength selective member has the waveform structure on at least one of the upper surface and the bottom surface of the wavelength selective member in a second cross sectional view, and a pseudo traveling direction of the waveform structure of the wavelength selective member faces to a second direction substantially orthogonal to the first direction.

Abstract
A transparent solar heat absorbing apparatus includes a transparent member allowing sunlight to pass through, a wavelength selective member disposed beneath the transparent member, a heating tank formed between the transparent member and the wavelength selective member. The wavelength selective member allows light in a transmission range including at least a visible wavelength range to pass through and reflects light in a reflection range including at least an infrared wavelength range. At least one of the transparent member and the wavelength selective member has a waveform structure on at least one of its upper surface and bottom surface.
