A pressure fluctuation suppression energy dissipator and fluid-structure interaction optimization method for liquid hydrogen pipelines
This invention provides a liquid hydrogen pipeline pressure fluctuation suppression energy dissipator and a fluid-structure interaction optimization method, relating to the field of liquid hydrogen storage and transportation safety technology. The energy dissipator adopts a modular integrated design, including a damping vibration reduction module, a gradient throttling module, and a pressure buffer module. The damping vibration reduction module has a corrugated damping inner wall combining spring damping and bellows; the gradient throttling module consists of multiple throttling plates with gradient-changing orifice parameters; the pressure buffer module is separated by an inert gas chamber and a liquid chamber containing a stored liquid layer by a gas-liquid separation membrane. Simultaneously, this invention proposes a corresponding fluid-structure interaction optimization method. By establishing a fluid-structure interaction model, the physical effects of the energy dissipator are abstracted into flow resistance, flow rate, and flow capacity parameters, solved using the method of characteristics, and the energy dissipation effect is verified by optimizing structural parameters. This invention achieves multi-structure synergistic energy dissipation, reducing liquid hydrogen pressure fluctuation amplitude by more than 40%, and is cryogenically resistant and compact, making it suitable for cryogenic liquid hydrogen transportation systems in the aerospace and energy fields.

An adaptive PDO fast charging power supply circuit and charger
ActiveCN224289326UImprove experiencereduce volumeBatteries circuit arrangementsElectric powerOvervoltageLow voltage
This utility model discloses an adaptive PDO fast charging power supply circuit and charger. A protocol chip receives GPIO signals and controls the PDO output voltage at the output port. One end of the input circuit can be electrically connected to a wide-voltage AC mains circuit, and the other end is connected to a voltage conversion circuit. The voltage conversion circuit converts the input voltage to a wide-voltage AC mains circuit and then to a specified voltage output sampling circuit. The secondary winding of the voltage conversion circuit samples the input voltage and transmits the voltage information to the protocol chip via GPIO lines. The output port is used to electrically connect to external devices and provide them with a specified output voltage for charging. The circuit of this application meets safety and temperature standards without increasing size, and is more suitable for domestic and international application scenarios. This adaptive PDO fast charging 100W power supply circuit samples the input voltage through transformer T1A, generates GPIO signals to the protocol chip, and thus changes the PDO, achieving adaptive PDO for high and low voltage inputs. This enables domestic compatibility with international voltage applications and reduces the size of existing market products.
