Definitions
- the present invention relates to a double wall diffusion bonded heat exchanger with micro-channels, commonly known as a printed circuit heat exchanger.
- Printed circuit heat exchangers offer significant space savings when compared to industry standard shell & tube heat exchangers, which have been in use for some time. They also offer the capability to operate at high pressures and low temperatures, which is ideal for the application of liquefied fuels such as LNG, LEG, LPG, LH 2 .
- LNG, LEG, LPG, LH 2 liquefied fuels
- LH 2 liquefied fuels
- one of the disadvantages of using these fuel types is that they are highly explosive, and even small leakages can lead to explosions as they vaporize in air and form highly combustible mixtures.
- Double wall piping systems typically have an inner pipe, and a secondary barrier in the form of an outer pipe, with an annular space in between which can be used to monitor any leakages of the inner pipe.
