Abstract:
A thermal management system for gas flow from an on board high pressure vehicle gas storage tank comprising an on board heat source operatively interconnected with a heater disposed in proximity to the metal component gas outlet flow control system of the on board tank; a thermostat regulating the flow of heat to the heater such that the thermostat regulates the temperature of the metal component outlet flow control system of the tank to a temperature corresponding to at least the minimum lower limit temperature permitted by the temperature tolerance range of metal component outlet flow control system of the tank; and an optional insulating shroud circumferentially disposed surrounding the gas flow heater installed in the system.
Abstract:
A pressure tank including, a tank wall; a supporting member which includes fiber reinforced plastic and supports an outer surface of the tank wall; a supersonic wave sensor which is connected to the tank wall, and which detects a sonic wave propagated in the tank wall; and an internal abnormality determination member which is connected to the supersonic wave sensor, and which determines whether an internal abnormality exits in the tank wall, wherein the internal abnormality determination member determines the existence of the internal abnormality based on the detection result during gas is charged into the pressure tank, and outputs an abnormality signal when the internal abnormality was determined to exist.

Abstract:
A heat management system for a high pressure gas tank comprising a loop circulation path for the gas including a path through an internal heat exchanger in the tank and a path through a heat exchanger external to the tank, wherein, in the instance of refueling, the refueling gas circulates multiple times in the loop through the internal heat exchanger and the external heat exchanger and in the course of circulation, a portion of the gas from the refuel line is introduced into the tank. In a reverse circulation during driving, the tank is warmed by heat exchange from the external heat exchanger to the internal heat exchanger.
Abstract:
Apparatus wherein the compression heat of refueling of a high pressure storage tank is evacuated from the interior of the tank in which a gas circulating within the tank passes through an ejector pump powered by the mechanical energy of the refueling gas as the gas traverses from the high pressure refuel depot to the storage tank and the circulating gas absorbs the refueling heat and carries the heat to a cooling system before the gas is introduced into the tank for storage.
Abstract:
A pressure vessel includes a liner, a reinforcing layer, and a protective layer. An inside of the liner forms a reserving chamber. The reinforcing layer is made of fiber reinforced plastic and is provided on an outer surface of the liner. A protective layer is provided on an outer surface of the reinforcing layer and includes fiber materials and a thermally foamed material. The thermally foamed material is interposed between the fiber materials.

Provided is a gas tank wherein the pressure of gas filled in the tank hardly increases. A hydrogen tank (1) includes: a container main-body (10) into which hydrogen is filled; a first thermal-foam heat insulation layer (21) provided on the outer surface (11) of the container main-body (10); a belt fitting region (16) virtually provided at a portion of the outer surface (11) of the container main-body (10); a belt (31), wherein the back surface (35) being a part of the surfaces of the belt (31) is in contact with the belt fitting region (16), and wherein the belt (31) is fixed to a vehicle body (141) so that the container main-body (10) is fixed to the vehicle body (141); and a second thermal-foam heat insulation layer (41) provided on a surface of the belt (31) other than the back surface (35).
Abstract:
A high pressure fuel flow control device wherein pressure sensors are interposed on either side of the main restriction point of a refueling depot when the vehicle tank(s) to be refilled are interconnected in a flow circuit that connects the refilling depot and the vehicle tanks. The sensors measure pressure on the side of the depot tank[s] and pressure on the side of the vehicle tank at a restriction point in the gas flow circuit. Flow from a tank is complete and a tank is switched when the difference in the pressures sensed on opposite sides of the restriction point approaches zero or slightly greater than zero.
Abstract:
A system for increasing the overall efficiency of a high pressure gas fueled vehicle and refilling station infrastructure wherein the compression heat of high pressure refueling of an on board tank is absorbed by a temperature dependent melting/solidifying media within the interior of an on board tank and may be dispersed through an external radiator.
Abstract:
A warming system for high pressure storage tanks for hydrogen and CNG gas fuel wherein a warming device is installed upon a tank port that is interconnected in thermal communication with a metal liner within the tank and heat derived from an on board vehicle heat source is transmitted by conduction from the tank port to the tank interior. Heating ameliorates mechanical stresses to the tank and the component parts of the tank assembly caused by the thermal conditions of the tank environment and thermal changes in gas temperature associated with the depletion of high pressure gas from the tank.
