Technical Field
[0001] This utility model belongs to the field of automotive heater technology, specifically relating to an automatically adjustable air intake volume adaptive high-altitude electronic fuel injection heater. Background Technology
[0002] Currently, existing electronic fuel injection heaters are widely used in buses, public buses, construction machinery, and trucks for low-temperature engine starting, windshield defrosting, and passenger compartment heating. With the booming development of the transportation industry and people's increasing demands for comfort, air conditioning in summer and heating in winter have become essential equipment for vehicles.
[0003] However, the effectiveness of heaters is affected by altitude, especially in high-altitude areas. Air density decreases with altitude, and at high altitudes, heaters may drip oil, smoke, or fail to ignite. Such malfunctions require manual intervention, which is troublesome and necessitates professional personnel. Cities in Tibet are far apart, and repair shops are scarce; if a problem occurs, the vehicle is unlikely to start, and roadside assistance requires significant time and expense.
[0004] Therefore, it is necessary to design an electronically controlled fuel injection heater that can work normally across the entire altitude range. At plains or low altitudes, the controller does not need to participate in the adjustment, while at high altitudes, the opening is automatically adjusted to increase the air intake so that the heater can work normally. This is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the present invention provides an automatically adjustable air intake volume high-altitude adaptive electronic fuel injection heater. The present invention automatically adjusts the opening of the air intake regulator at high altitudes to increase the air intake volume so that the heater can work normally.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatically adjustable air intake adaptive high-altitude electronically controlled heater includes a burner, a heat exchanger, a circulating water pump, a controller, and an air intake regulator. The burner is located at the front end of the heat exchanger, and the circulating water pump is installed at the water inlet on the front side of the heat exchanger for circulating antifreeze. The controller is located on the surface of the burner, and the air intake regulator is located at the air inlet at the front end of the burner. The air intake regulator includes an altitude sensor, a control unit, and an air intake actuator. The altitude sensor measures the altitude in real time, the control unit measures the air intake opening, and controls the opening through the air intake actuator.
[0008] Furthermore, the heat exchanger includes an inner sleeve and an outer sleeve, with a cavity formed between the inner sleeve and the outer sleeve. A circulating guide bar is pre-placed in the interlayer to heat the low-temperature antifreeze.
[0009] Furthermore, the burner includes an aluminum bracket, a combustion chamber, an air supply shroud, a combustion-supporting fan, a motor, an oil pump, and an ignition device. The combustion chamber is located at one end of the aluminum bracket and extends into the interior of the inner sleeve. The air supply shroud and the aluminum bracket form a sealed space. The motor is installed inside the aluminum bracket. The combustion-supporting fan is installed at one end of the motor. The oil pump is installed at the other end of the motor. An oil injector is located at the end of the oil pump and extends into the interior of the combustion chamber. The ignition device is installed on the aluminum bracket and is connected to the oil injector.
[0010] Furthermore, a vent valve is provided on the upper surface of the outer jacket of the heat exchanger.
[0011] Furthermore, the heat exchanger has a water outlet at the top of its outer casing and a drain valve at the bottom of its outer casing.
[0012] Furthermore, a temperature sensor and an overheat protector are also provided at the top of the heat exchanger.

[0027] Example 1
[0028] like Figure 1-5 As shown, this embodiment discloses an automatically adjustable air intake volume high-altitude adaptive electric injection heater, including a burner 12, a heat exchanger, a circulating water pump 4, a controller 3, and an air intake regulator.
[0029] The burner 12 is located at the front end of the heat exchanger, which includes an inner sleeve 14 and an outer sleeve 13, with a cavity formed between them. A circulating guide bar is pre-installed in the interlayer to heat the low-temperature antifreeze. A circulating water pump 4 is installed at the water inlet on the front side of the heat exchanger to circulate the antifreeze. A controller 3 is located on the surface of the burner 12 to control the operation of the heater. An air intake regulator is located at the air intake vent 2 at the front end of the burner 12. The air intake regulator includes an altitude sensor, a control unit, and an air intake actuator. The altitude sensor measures the altitude in real time, the control unit measures the air intake opening, and the air intake actuator controls the opening. When the air intake opening does not match the altitude, the air intake actuator adjusts to a suitable position to meet the air requirements for normal heater operation.
[0030] The burner 12 includes an aluminum bracket 15, a combustion chamber, an air supply shroud, a combustion-supporting fan, a motor, an oil pump 16, and an ignition device 5. The combustion chamber is located at one end of the aluminum bracket 15 and extends into the interior of the inner sleeve 14. The air supply shroud and the aluminum bracket 15 form a sealed space. The motor is installed inside the aluminum bracket 15. The combustion-supporting fan and the oil pump 16 are respectively fixedly connected to the motor shaft. The combustion-supporting fan is installed at one end of the motor, and the oil pump is installed at the other end of the motor. The oil pump 16 is equipped with an oil injector 17 at its end, which extends into the interior of the combustion chamber. The ignition device 5 is installed on the aluminum bracket 15 and is connected to the oil injector 17.
[0031] In a preferred embodiment of this utility model, the upper surface of the heat exchanger jacket 13 is provided with a vent valve 9 for venting air, the top of the heat exchanger jacket 13 is provided with a water outlet 8, the bottom of the heat exchanger jacket 13 is provided with a drain valve 11 for draining antifreeze, the top of the heat exchanger is also provided with a temperature sensor 6 and an overheat protector 7, and the bottom of the heat exchanger is provided with a mounting bracket 10 for easy installation of the heater.
[0032] The working principle of this utility model is as follows: After the heater is turned on, the air volume regulator 1 starts working, the altitude sensor measures the altitude, and sends the measurement result to the control unit with 12-bit ADC precision data. The control unit measures the air intake opening. If the altitude, after conversion, is greater than the opening, the controller 3 increases the air intake; if the altitude, after conversion, is less than the opening, the controller 3 decreases the air intake. The heater controller 3 controls the motor to work. One end of the motor drives the combustion fan to rotate, and air enters the heater through the air intake cover. The other end of the motor drives the oil pump 16 to rotate, and fuel enters the oil pump 16. The fuel injector sprays high-pressure fuel mist, which is fully mixed with the combustion air and then ignited by the ignition device 5, burning in the combustion chamber. The heat generated by combustion is transferred to the antifreeze in the heat exchanger through the conductive plates.
[0033] The heated antifreeze is circulated from the outlet of the heat exchanger to the engine or vehicle cooling system by the action of the circulating water pump 4, to meet the cold start requirements or provide heating or defrosting for the vehicle.
[0034] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
