Abstract: An oil-cooled motor cooling system, comprising an oil collection assembly (1), an oil spray tube (2), and a motor (4). A plurality of oil spray holes (23) are provided on the oil spray tube (2), and thereby cooling oil within the oil spray tube (2) can be sprayed onto the oil collection assembly (1). The oil collection assembly (1) comprises a first oil collection pan (11) and a second oil collection pan (12) which are circular arc-shaped and provided with a plurality of through holes, and cooling oil in the oil collection pans further passes through the through holes and drips onto a stator winding (44) and a stator core (45). The present oil-cooled motor cooling system is used in a vehicle. By means of the oil collection assembly and the oil spray tube which both have relatively simple structures, cooling of the stator winding and the stator core, which emit a relatively large amount of heat, is implemented.

Abstract: The invention discloses a physically unclonable structural-color anti-counterfeiting label with artificial intelligence (AI) authentication, which is formed by doping micron-sized particles into disorderedly arranged monodisperse submicron-sized particles and coating onto a black substrate; alternatively, by doping micron-sized particles and black nanoparticles into disorderedly arranged monodisperse submicron-sized particles and coating onto a substrate. The disordered arrangement of monodisperse submicron-sized microspheres has a special effect on light to make the anti-counterfeiting label show a specific structural color. AI is used to learn the anti-counterfeiting label images obtained from an optical microscope and memorize their structural characteristics to form an anti-counterfeiting label database.
