Description

Hydrogen cooling device for hydrogen fuel automobile

Technical Field

The invention relates to the technical field of hydrogen fuel automobiles, in particular to a hydrogen cooling device for a hydrogen fuel automobile.

Background

As its name implies, a hydrogen-powered vehicle uses hydrogen as an energy source to convert chemical energy generated by hydrogen reaction into mechanical energy to propel the vehicle. Hydrogen energy vehicles are classified into two types, one is a hydrogen internal combustion engine vehicle, which uses an internal combustion engine to burn hydrogen (usually obtained by decomposing methane or electrolyzing water) to generate power to propel the vehicle. Hydrogen or a substance containing hydrogen reacts with oxygen in the air in a fuel cell to generate electric power to drive an electric motor, and the electric motor drives a vehicle. Among them, a hydrogen fuel cell is used as a power source for a hydrogen fuel vehicle, and the hydrogen fuel cell is a power generation device that directly converts chemical energy of hydrogen and oxygen into electric energy. The basic principle is that hydrogen and oxygen are respectively supplied to the anode and the cathode by the reverse reaction of electrolytic water, and after the hydrogen diffuses outwards through the anode and reacts with the electrolyte, electrons are released to reach the cathode through an external load, so that the fuel cell has no pollution to the environment. It is through electrochemical reaction, rather than combustion (gasoline, diesel) or energy storage (battery) -the most typical traditional backup power scheme. Combustion releases pollutants like COx, NOx, SOx gases and dust. As described above, the fuel cell generates only water and heat. If hydrogen is generated by renewable energy sources (photovoltaic cell panels, wind power generation and the like), the whole cycle is a complete process without harmful substance emission, the fuel cell runs quietly, and the noise is only about 55dB, which is equivalent to the level of normal conversation of people. This makes the fuel cell suitable for indoor installation, or in the place where there is a limit to noise outdoors, the power generation efficiency of the fuel cell can reach more than 50%, which is determined by the conversion property of the fuel cell, directly converts chemical energy into electric energy without intermediate conversion of thermal energy and mechanical energy (generator); the hydrogen combustion internal combustion engine is another development way, and a hydrogen internal combustion vehicle is different from a hydrogen fuel cell vehicle. A hydrogen internal combustion engine is a version of a conventional gasoline internal combustion engine with minor modifications. Hydrogen combustion directly combusts hydrogen without the use of other fuels or the production of steam for venting. The problem with these vehicles is that the hydrogen fuel is quickly depleted. The hydrogen-filled cylinders can only travel miles and quickly become energy-free. On the other hand, various methods are being studied to reduce the consumed space, such as with liquid hydrogen or hydrides.

At present, hydrogen fuel automobiles adopting hydrogen as a power source of an internal combustion engine generally use liquid hydrogen as the power source for improving the endurance performance, but the liquid hydrogen needs to be stored in a steel cylinder for use when in use, but the steel cylinder can be influenced by high temperature due to the fact that the automobile driving environment is generally severe, the existing hydrogen fuel automobiles generally utilize the air flow of the automobile during driving to effectively dissipate heat of the hydrogen tank, but the heat dissipation effect is extremely limited, and the hydrogen tank can not be effectively dissipated when the automobile idles, so that the practicability is low.
