[0033] Reference Figure 1-2 A fuel heating and warm air system for the cab of a new energy vehicle is used for heating the cab of a vehicle in order to keep the cab of the vehicle at a suitable temperature at all times while reducing the power battery consumption of the new energy vehicle.

[0034] The fuel heating and warm air system of the new energy vehicle cab comprises a fuel tank 1, a fuel pump 2, a fuel burner 3, a heat exchanger 4, a water pump 5, a heater 6 and a controller;

[0035] The fuel tank 1 is connected to the fuel burner 3 through a pipeline, and the oil pump 2 is arranged on the pipeline between the fuel tank 1 and the fuel burner 3. An oil extraction pipe 101 and an oil return pipe 102 are arranged between the oil pump 2 and the fuel tank 1. An oil inlet pipe is arranged between the oil pump 2 and the fuel burner 3. The oil pump 2 extracts the fuel inside the fuel tank 1 through the oil extraction pipe 101, and then pumps it into the fuel burner 3 through the oil inlet pipe for combustion. The controller can control the output oil volume of the oil pump 2, thereby controlling the heat generation of the fuel burner 3, and the excess fuel is returned to the fuel tank 1 through the oil return pipe 102 for storage.

[0036] The fuel burner 3 is provided with an air inlet 301 and an air outlet 303. A muffler 302 is provided at the air inlet 301. When the fuel burner 3 burns, the air sucked in from the air inlet 301 and passing through the muffler 302 will be heated. The heat exchanger 4 includes a gas pipeline and a liquid circulation pipeline. The gas pipeline is connected between the fuel burner 3 and the heat exchanger 4. The air heated by the combustion of the fuel burner 3 will be output to the heat exchanger 4 through the gas pipeline. The liquid circulation pipeline is connected between the heat exchanger 4 and the heater 6. The heat exchanger 4 allows the air carrying heat energy in the gas pipeline to heat the antifreeze inside the liquid circulation pipeline. The heated antifreeze is output to the heater 6 through the liquid circulation pipeline and heats the air blown out of the heater 6. Since the heater 6 is arranged inside the cab, the warm air will be blown into the cab, thereby raising the temperature inside the cab.

[0037] The water pump 5 is arranged on the liquid circulation pipeline, and an expansion water tank 501 is provided on the liquid circulation pipeline. The expansion water tank 501 is connected to the water pump 5 through a pipeline. The speed and flow of the water pump 5 can be controlled by the controller, thereby controlling the liquid circulation speed inside the liquid circulation pipeline and controlling the air temperature blown out by the heater 6.

[0038] Since a heat exchanger temperature sensor is provided on the heat exchanger 4 and a heater temperature sensor is provided on the heater 6, the controller controls the output oil volume of the oil pump 2 and the speed flow of the water pump 5 through feedback from the heater temperature sensor and the heat exchanger temperature sensor, thereby performing dual control over the temperature in the system, thereby being able to accurately control the air temperature blown out by the terminal heater 6.

[0039] In addition, the new energy vehicle cab fuel heating and warm air system also includes a power supply, which is connected to the oil pump 2, the fuel injector 3, the heat exchanger 4, the water pump 5, the heater 6 and the controller to supply power to the oil pump 2, the fuel injector 3, the heat exchanger 4, the water pump 5, the heater 6 and the controller, and since fuses are arranged between the power supply and the oil pump 2, the fuel injector 3, the heat exchanger 4, the water pump 5, the heater 6 and the controller, the safety of each line can be controlled by the fuse. When abnormally high temperature appears in the system and the line exceeds a certain load, the fuse in the fuse blows and the warm air system automatically shuts down, which protects the cab and personnel. The controller also includes a manipulator and an instrument. The manipulator is used to control the controller to realize manual control of the cockpit warm air system, and the instrument is used to display data, so that the temperature of the warm air system can be understood in real time.

[0040] The working principle of the fuel heating and warm air system in the cab of the new energy vehicle is as follows: the fuel is extracted from the fuel tank 1 through the fuel pump 2 and the fuel extraction pipe 101, and then the fuel is pumped into the fuel burner 3 through the fuel inlet pipe for combustion. The controller can control the output oil volume of the fuel pump 2, thereby controlling the heat generation of the fuel burner 3, and the excess fuel is returned to the fuel tank 1 through the return pipe 102 for storage;

[0041] The fuel burner 3 generates heat, thereby heating the air in the gas pipeline. The air heated by the fuel burner 3 is output to the heat exchanger 4 through the gas pipeline. The heat exchanger 4 exchanges heat between the air carrying heat energy in the gas pipeline and the antifreeze in the liquid circulation pipeline. The antifreeze is heated. The heated antifreeze is output to the heater 6 through the liquid circulation pipeline, thereby heating the air blown out of the heater 6. The heater 6 blows out warm air, thereby raising the temperature inside the cab.

[0042] The heat exchanger temperature sensor detects the temperature of the heat exchanger 4 and feeds back to the controller, and the heater temperature sensor detects the temperature of the heater 6 and feeds back to the controller, thereby performing dual temperature detection on the system. The controller controls the output oil volume of the oil pump 2 and the speed flow of the water pump 5 according to the dual temperature feedback, and performs dual feedback control on the temperature in the system, thereby being able to quickly and accurately control the air temperature blown out by the terminal heater 6.

[0043] It should be noted that the controller, temperature sensor and temperature feedback control circuit involved in the present invention are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to the internal structure and method.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
