DUCT OPTIMIZATION TO PREVENT FREEZING |
摘要 |
In a device for conveying liquids or moist gases through a closed duct in a vehicle fuel cell power systems, freezing of the duct is prevented by providing a part of its internal wall flow passages or flow chambers with a nonwoven material. The nonwoven material absorbs liquid in disperse form at low temperatures through its capillary action and inhibits premature ice formation. |
