Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0014] A liquefied natural gas cylinder liner with cooling function, one end of the gas cylinder liner is provided with a safe gas phase space, and the gas cylinder liner is provided with a liquid inlet spray pipe and a capacitive liquid level gauge. The shower pipe is arranged on the tank wall, and the capacitive liquid level gauge is mainly composed of a display, a main transmitter, an auxiliary transmitter, a liquid level sensor and a pressure sensor. The middle position in the gallbladder. If there are multiple gas cylinders, the liquid level sensor and pressure sensor in each gas cylinder are connected to the auxiliary transmitter, and the auxiliary transmitter is connected to the main transmitter after being connected in series. The volume of the inner tank is 400-700L.

The invention discloses a liquefied natural gas cylinder inner container with a cooling function. A safety gas phase space is arranged at one end of the gas cylinder inner container. A liquid inlet spraying pipe and an electric capacity type liquidometer are arranged in a container body of the gas cylinder inner container. The liquid inlet spraying pipe is arranged on the wall of the container body. The electric capacity type liquidometer is arranged in the middle of the interior of the container body of the gas cylinder inner container. According to the liquefied natural gas cylinder inner container with the cooling function, the safety gas phase space is arranged, and a vacuum space is formed between the safety gas phase space and a shell. In this way, the inner container can be better protected, and a gas cylinder can be supported and protected.
Description
technical field [0001] The invention relates to an automobile energy storage device, in particular to a liquefied natural gas cylinder liner with a cooling function. Background technique [0002] As a vehicle fuel, liquefied natural gas (LNG) has the characteristics of low pollution, high combustion calorific value, long continuous driving mileage, and high safety performance. It has become a "green" alternative fuel with great potential. LNG gas cylinders for vehicles include an inner tank and an outer shell. The inner tank is usually connected to the outer shell by a support. Since the vehicle faces various complex road conditions during operation, and the inner tank of the gas cylinder is loaded with LNG cryogenic liquid fuel, the support has Sufficient strength and small heat transfer performance. The existing natural gas cylinder liner is hard-connected to the gas cylinder shell, which easily causes the liner to overheat; and there is no liquid inlet spray pipe to fill...
