A hydrogen-fired heating device and its control method

Abstract

The invention discloses a hydrogen-burning heating device and a control method thereof, belonging to the technical field of fuel cells. The hydrogen-fired heating device includes a combustion chamber, which is provided with a first inlet and a second inlet, and the first inlet is provided with a first regulating valve for regulating the flow of hydrogen, and the second inlet is provided with a second regulating valve for regulating the flow of air, The outer side of the combustion chamber is provided with fins for transferring the heat in the combustion chamber; the housing, which is covered on the outer side of the combustion chamber, is provided with a first outlet for cooling liquid to flow out and a first outlet for cooling liquid to flow in. The third inlet, and the third inlet is provided with a first sensor for detecting the third inlet temperature, and the first outlet is provided with a second sensor for detecting the first outlet temperature; a control module, which is connected with the first regulating valve and the second regulating valve The valve control connection is in signal connection with the first sensor and the second sensor. The utility model has the advantages of not being affected by ambient temperature, high heating power, simple structure and environmental protection.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a hydrogen-burning heating device and a control method thereof. Background technique [0002] With the continuous growth of the national economy and the continuous improvement of people's living standards, automobiles have become an essential tool for travel. However, with the increasing smog in cities, new energy vehicles have become the current research and development direction of automobiles. Among them, fuel cell vehicles have attracted more and more attention from the industry and consumers due to their fast filling, zero emissions and low temperature resistance. A fuel cell vehicle is an electric vehicle, and a fuel cell vehicle is a vehicle powered by electricity generated by a vehicle-mounted fuel cell device. [0003] In winter, especially in the north, the outdoor temperature is extremely low. During the low-temperature cold start process of fuel cell vehicles, in...

Problems solved by technology

However, in the ultra-low temperature environment, the discharge capacity of the power battery as the power source of the electric heating device is limited, especially in the low temperature state where the outdoor temperature is -30°C, the power battery basically does not have the discharge capacity, which leads to the failure of the power battery as a fuel cell system. The important auxiliary electric heating device for cold start at ultra-low temperature cannot start to work; and in a low temperature environment, when the power battery has the discharge capacity, the power battery is continuously discharged at low temperature to support the operation of the electric heating device, which will directly affect the power battery. Due to the long service life, the user needs to replace the power battery frequently; at the same time, due to the small power of the electric heating device, the heating effect on the fuel cell system is limited, so that the fuel cell system reaches the ideal operating temperature slowly.
