Definitions

  • the invention relates to a pressure reduction system for a high-pressure tank according to the preamble of claim 1.
  • Vehicles powered by hydrogen or natural gas for example, use high-pressure tanks for fuel storage. Pressures of several hundred bar, such as 700 bar in passenger cars, are typical for these high-pressure tanks.
  • the high-pressure tanks are equipped with a thermal pressure relief device, which is usually a pipe system or a relief pipe that empties the high-pressure tanks in the event of a vehicle fire.
  • Relief pipes or thermal pressure relief devices directly coupled to a high-pressure hydrogen tank are already known in the prior art. These are typically stainless steel pipes that provide a relatively They exhibit high mechanical strength and can therefore withstand increased pressure conditions during fuel discharge. Depending on the system design, the line pressure reaches up to approximately 80-95% of the tank pressure when the thermal pressure relief device is activated and the hydrogen flows from the high-pressure tank into the pipeline.
  • a pressure reducer is provided in the thermal pressure relief device according to the invention for reducing the pressure when the high-pressure tank is relieved.
  • the thermal pressure relief device is designed as a polymer tube.
  • Polymer tubes are particularly cost-effective to manufacture and, at the same time, very lightweight compared to stainless steel tubes.
  • the polymer tube can be manufactured, for example, using a simple injection molding process.
  • the invention provides that the pressure reducer accelerates the flow at the outlet to supersonic speed. Due to the acceleration of the fluid or fuel into the supersonic range, in the A thermal pressure relief device achieves an effective pressure reduction downstream or in the direction of flow.
