[0043] Air heating circulation path: The fresh air inlet is connected to the combustion unit, providing fresh air to the unit. After the combustion unit heats the air, it is transported out through a duct connected to the heated air outlet. Simultaneously, the exhaust gas generated by the combustion unit is discharged through a pipe connected to the combustion air exhaust port.

[0044] The specific working principle is as follows:

[0045] Start-up phase:

[0046] (1) The user issues a start command through the control panel, which is transmitted to the combustion device through the power plug.

[0047] (2) The fuel in the fuel tank assembly begins to flow through the fuel line to the fuel filter, which filters the fuel to remove impurities and particles.

[0048] (3) The filtered clean fuel enters the combustion device.

[0049] Combustion heating stage:

[0050] (1) Fresh air enters the combustion device through the fresh air inlet to provide the necessary oxygen for fuel combustion.

[0051] (2) The combustion device ignites the fuel oil and burns it, releasing a large amount of heat, which is used to heat the air entering from the fresh air inlet.

[0052] (3) The heated air is discharged from the heated air outlet through the air duct to provide warm air for the interior of the commercial vehicle or to preheat other systems.

[0053] Monitoring and control phase:

[0054] (1) The carbon monoxide sensor continuously monitors the concentration of carbon monoxide in the exhaust gas of the combustion device, i.e., in the air, and transmits the monitoring data to the control panel in real time through the power plug.

[0055] (2) If the carbon monoxide concentration exceeds the safety threshold, the control panel will immediately issue an alarm and send a command to the combustion device to stop combustion via the power plug to prevent carbon monoxide leakage from causing danger.

[0056] (3) Users can also adjust the power of the combustion device through the control panel to control the temperature and air volume of the warm air. The control panel transmits the adjustment command to the combustion device through the power plug to achieve the corresponding adjustment.

[0057] Exhaust gas discharge stage:

[0058] The exhaust gases produced by the combustion device, such as carbon dioxide, carbon monoxide, and nitrogen oxides, are discharged outside the vehicle through the combustion air exhaust port via pipes, ensuring the safety of the air environment inside the vehicle.

[0059] The installation process of this commercial vehicle fuel air PTC heating device is as follows: according to the commercial vehicle body structure, the mounting bracket is fixed to a preset position on the side of the vehicle body, the air guide channel is connected to the fresh air inlet, the PTC heating module is embedded and the circuit connection is completed.

[0060] In another specific embodiment, the combustion device includes: a heated air outlet 6, a fresh air inlet 7, a combustion air exhaust port 8, and a combustion air intake port 11 disposed on the combustion housing. A fan 13 and a motor 14 are disposed at one end of the combustion housing near the heated air outlet 6, and a combustion chamber 12 and heating fins 15 are disposed at the other end. The motor 14 is connected to the fan 13. During operation, the motor 14 controls the fan 13 to start, so that cold air flows into the combustion device through the fresh air inlet 7, is heated through the combustion chamber 12, and finally the heated cold air becomes hot air and enters the vehicle through the heated air outlet 6 to heat the people in the vehicle.

[0061] The heating fins 15 are circumferentially arranged on the side walls of the combustion chamber 12 to improve the heating efficiency of cold air.

[0062] The combustion chamber 12 is connected to the fuel outlet of the fuel supply path. In this way, the fuel in the fuel supply path can directly enter the combustion chamber 12 after being injected from its outlet.

[0063] In this embodiment, the combustion air exhaust port 8 and the combustion air inlet 11 are connected to the combustion chamber 12. The combustion air inlet is used to introduce combustion-supporting gas, such as oxygen, chlorine, or some oxidants, into the combustion chamber 12. The combustion air exhaust port can be connected to the bottom side wall of the combustion chamber 12, mainly used to discharge the exhaust gas generated after fuel combustion. Preferably, the lower side of the combustion device is provided with a combustion air exhaust port for discharging combustion exhaust gas from the combustion chamber 12 and a combustion air inlet for introducing combustion-supporting gas into the combustion chamber 12; the pipeline connecting the fuel tank assembly is connected to the lower side of the combustion device and enters the combustion chamber 12.

Furthermore, the temperature sensor is connected to the controller signal, sending its detected temperature values ​​to the controller. This allows the controller to adjust the amount of heating applied to the cold air, bringing the interior temperature closer to the value confirmed by the user.

[0065] Of course, the combustion device in this invention can also adopt other existing structures, consisting of a combustion chamber, a heat exchanger, a fuel supply system, an air supply system, and a control system. A motor connects to the power supply, driving a fan while an oil pump supplies fuel to the combustion chamber. The fuel is atomized at the combustion chamber inlet and mixes with the air coming in from the self-ignition air inlet, then ignited by an ignition device. The heat generated by combustion is exchanged with cold air coming in from the cold air inlet via the heat exchanger, turning the cold air into warm air, which is then supplied to the passenger compartment through the warm air outlet. The entire heater operation is controlled by a controller.

[0066] This utility model discloses a PTC heating device for commercial vehicle fuel air. It provides warm air to the interior of the commercial vehicle through a combustion device, or preheats other systems. The combustion device has a fast response and uniform heating, rapidly increasing air temperature, improving fuel atomization, and ensuring engine low-temperature start-up performance. This reduces energy consumption of the power battery, achieving efficient heating of fuel air in commercial vehicles and improving the vehicle's adaptability to low-temperature environments. Furthermore, the modular design of the combustion device allows for quick disassembly of the PTC heating device, and the airflow channel is easy to clean, reducing maintenance costs.
