The invention relates to a hydrazine arc thruster support in split design, and relates to the field of spacecraft supports, the hydrazine arc thruster support comprises a generator support and a thruster support, the generator support is fixedly connected with a fuel gas generator, the thruster support is fixedly connected with an arc thruster, and the generator support is made of an aluminum alloy material and is in heat conduction connection with a satellite mounting surface; the thruster bracket is made of a titanium alloy material and is in heat insulation connection with a satellite mounting surface; and one side of the generator bracket is fixedly connected with one end of the thruster bracket through a blocky bracket connecting piece. The electromagnetic valve has the advantage that the use temperature and the mounting surface temperature of the electromagnetic valve are effectively reduced.

The application provides a substrate carrier, a conveying system, a vacuum system and a method for operating the substrate carrier, the substrate carrier comprising a bearing frame, a substrate bearing surface, a groove and a heat absorbing sheet, the substrate bearing surface is used for placing a substrate, a groove is arranged on the bottom side of each substrate bearing surface, a heat absorbing sheet is arranged on the bottom surface of the groove, the emissivity of the first surface of the heat absorbing sheet is greater than the emissivity of the second surface of the groove bottom surface and / or the heat absorbing sheet, in this case, the low emissivity surface can inhibit heat dissipation, and the high emissivity surface can allow heat to pass through efficiently, therefore the first surface of the heat absorbing sheet can reabsorb the thermal radiation of the substrate and transmit to the second surface or the groove bottom surface, and good heat dissipation effect is achieved. This technology is simple and low in cost, meanwhile, the coating speed does not need to be reduced, and the problem of temperature rise of the substrate can be effectively solved without reducing the processing efficiency.

The invention relates to a dual-module intercooler type fuel cell cathode inlet temperature and humidity cooperative control method. The method comprises the steps that fuel cell cathode air inlet real-time state parameters and operation parameters are obtained, a multivariable coupling prediction model is constructed after preprocessing, and a temperature and humidity reference and an oxygen stoichiometric ratio target reference are set in combination with heat exchange characteristics of a dual-module intercooler; then the core body heat exchange distribution proportion is regulated and controlled, humidification adjustment is matched, and the core body heat exchange distribution proportion and the humidification adjustment intensity are dynamically adjusted according to the real-time working condition; comparing the deviation between the adjusted actual temperature and humidity and the target temperature and humidity reference, and correcting the heat exchange distribution proportion and the humidifying adjustment parameter through a dynamic constraint correction model; cooperative regulation and control of cathode inlet temperature and humidity are realized, dynamic change of working conditions is adapted, and stable operation of the fuel cell is guaranteed.
