Hydrogen is pumped into the tank of a hydrogen car under high pressure. The heat added to the hydrogen by the compressor is cooled down again by the heat exchanger.
Cooling of the Hydrogen depends on the type of cooling system. In this case it is by a Shell & Tube liquid cooler, being cooled by using a refrigerant. The characteristics of this cooler are that there is no phase transition and the heat transfer takes place between two liquids.
Hydrogen is the future and is gaining ground. It is a sustainable alternative to fossil fuels. The hydrogen vehicles generate electricity from hydrogen and oxygen by means of a fuel cell. The electric motor(s) of the car is powered with this electricity. Instead of combustion gases, only water remains. Hydrogen is buffered at a medium pressure and must be at high pressure in the tank of the car. A refueling of approximately 4 kg of hydrogen (for 650 km of driving pleasure) should not take longer than a regular refueling. This partly determines the cooler. ROBOX has realized a compact design to fit in a container (in this case not the compact Micro Shell & Tube). This cooler is designed for the high pressures and cooling capacity that is required for the proper functioning of the filling station.
