Abstract: Disclosed is a sub-Kelvin temperature zone refrigeration mechanism. The sub-Kelvin temperature zone refrigeration mechanism includes a pulse tube refrigeration unit, first pre-cooling heat exchangers, a throttling refrigeration unit, second pre-cooling heat exchangers, an adsorption refrigeration unit, a third pre-cooling heat exchanger and a dilution refrigeration unit. The pulse tube refrigeration unit includes a pulse tube refrigeration part. The throttling refrigeration unit includes a throttling refrigeration part, and the throttling refrigeration part is connected with the adsorption refrigeration unit through the second pre-cooling heat exchangers so as to pre-cool the adsorption refrigeration unit. The adsorption refrigeration unit includes an adsorption refrigeration part, and the adsorption refrigeration part is connected with the dilution refrigeration unit through the third pre-cooling heat exchanger.

Abstract: The present disclosure provides a light transmission processing system and method for a solar chip module. The light transmission processing system includes: an ink printing unit configured to print a preset pattern on an upper surface of the chip module with a UV ink so that a hollowed out region is formed on an area of the upper surface of the chip module not covered by the pattern, the chip module including a transparent substrate and a chip layer superposed on an upper surface of the transparent substrate; a curing unit configured to cure the UV ink printed on the chip module with UV light to form a UV ink protective film; and a layer removing unit configured to remove a portion of the chip layer corresponding to the hollowed out region to expose a portion of the transparent substrate corresponding to the hollowed out region.

Abstract: A device for supporting an anti-glare plate and an anti-glare device are provided. The device for supporting an anti-glare plate includes a supporting member and a connecting member, the connecting member is connected with the supporting member and the anti-glare plate, and the anti-glare plate is capable of rotating relative to the supporting member. The present disclosure is used for fixing the anti-glare plate.
