  • Publication number: 20250026980
    Abstract: A preparation method of an indium phosphide quantum dot (InP QD) with a large Stokes shift includes: fully dissolving the indium precursor at a first temperature under isolation from oxygen and water, adding a phosphorus precursor, and heating to a second temperature to allow a reaction to obtain an indium phosphide (InP) core; adding a shell precursor to the InP core, and heating to a third temperature to obtain QD with a core-shell structure; and adding anionic and cationic precursors successively to the QD with the core-shell structure at the third temperature to obtain the InP QD with an emission peak adjustable in a range of 465 nm to 650 nm, a high quantum efficiency, and a large Stokes shift. The InP QD mainly has a large Stokes shift to inhibit self-absorption and non-radiative resonance energy transfer.

  • Patent number: 12058803
    Abstract: A circuit board assembly is applied to the field of electronic communications technologies to resolve a prior-art heat dissipation problem of a circuit board. The circuit board assembly combines, on a second circuit board, low-speed signals transmitted between a plurality of I/O modules and an IC chip, and then transmits the combined low-speed signals to the IC chip by using a low-speed cable. A low-speed signal sent by the IC chip to the plurality of I/O modules is extended to a plurality of low-speed signals on the second circuit board, and then the plurality of low-speed signals are separately sent to the plurality of I/O modules. This may be applied to a scenario in which a relatively large quantity of electronic components need to be disposed on a circuit board.

  • Publication number: 20230225081
    Abstract: A heat dissipation cabinet includes a cabinet body and a heat dissipation apparatus. A first accommodation region of the cabinet body can accommodate a plugboard in a stacked manner, and heat source components of the plugboard dissipate heat through the heat dissipation apparatus. An evaporator, a condenser, and an evaporation pipeline of the heat dissipation apparatus are connected to a liquid return pipeline to form a heat exchange loop, and the evaporator is in thermal contact with an outer surface of a heat source component. The condenser is disposed in a second accommodation region and located above the evaporator. A refrigerant flows in the heat exchange loop, to draw heat of the heat source component far to the condenser, and take away heat of the condenser using air generated by a fan. A second accommodation region is used as an independent air duct whose path is relatively short.
