Title:
VORTEX FILL
Document Type and Number:
WIPO Patent Application WO/2016/004033
Kind Code:
A3
Abstract:
Improved methods, systems, and devices for filling fuel tanks, particularly compressed natural gas (CNG) fuel tanks, are provided. Such methods, systems, and devices enhance heat rejection when the fuel tank is being filled to a temperature lower than that if such methods, systems, and devices were not used. Pressure sensor logic on a fuel station will be less prone to error in gauging the mass of the fuel in the tank, enabling the tank to be filled more accurately and fully. To enhance heat rejection, the fuel tank may be provided with a heat sink to passively facilitate heat transfer from the fuel tank interior to the exterior. Alternatively or in combination, the fuel tank can be provided with a fuel flow channel through which fuel from the fuel tank interior is circulated. The fuel flow channel can be actively cooled with a fan or water cooling system.
