Description

Technical Field

[0001] The utility model belongs to the technical field of heaters, and in particular relates to a low-power heater specially used for plateau environments. Background Art

[0002] Car heaters, as a device to increase the temperature inside the vehicle, are particularly important in cold seasons or low-temperature environments. Small-power heaters are mostly installed inside the vehicle's compartment. By drilling holes in the compartment floor, a channel for pipes to enter and exit is provided, and the heater is fixed. The heater is connected to the fuel tank installed on the outside of the vehicle body through an oil pipe and an oil pump for oil supply. The fuel is burned inside the heater to heat the air. However, when used in a plateau environment, due to the low oxygen content and temperature in the air, as well as the low environmental pressure, it is difficult for the fuel to burn completely at one time, which will cause certain waste. For this reason, we propose a small-power heater specifically for plateau environments. Utility Model Content

An oil pipeline 22 is connected to the partition 18 on the inner side of the first combustion chamber 8, and one end of the oil pipeline 22 is connected to the atomizing nozzle 23. An igniter 24 is installed on the side of the partition 18.

[0030] This device can meet the demand for full combustion of fuel under plateau conditions. Combined with the function of being able to transport a large amount of air to the combustion chamber and heat the air, it further improves the combustion efficiency of the fuel and is suitable for use in operating vehicles, trucks, etc. in plateau areas.

[0031] One end of the heater housing 2 is connected to an air inlet pipe 3 , and the other end of the heater housing 2 is connected to an air outlet pipe 4 .

[0032] The air inlet pipe 3 and the air outlet pipe 4 are used for drawing air into the interior of the heater housing 2 and for exhausting air from the interior of the heater housing 2 , respectively.

[0033] The diversion holes 19 are evenly distributed on the partition plate 18 in an annular shape.

[0034] The diversion holes 19 are evenly distributed in an annular shape on the partition plate 18, so that the air flow enters the combustion chamber 20 evenly.

[0035] Heat exchange fins 10 are provided on the outside of the first combustion chamber 8 and the second combustion chamber 9 .

[0036] The heat exchange fins 10 are used to exchange heat between the first combustion chamber 8 and the second combustion chamber 9 and the air circulating outside, thereby heating the air.

[0037] A combustion chamber 20 and an air intake chamber 21 are respectively provided on both sides of the partition 18 inside the first combustion chamber 8 and the second combustion chamber 9.

[0038] The air inlet chamber 21 is used for the entry of combustion-supporting airflow, and the combustion chamber 20 is used for mixing the combustion-supporting air with fuel droplets and burning to generate heat.

[0039] A screw base 25 is installed at the bottom of the heat-insulating shell 1 .

[0040] The screw base 25 is used to be fixed to the floor inside the vehicle compartment.

[0041] The working principle and use process of the present invention are as follows: when installing the device, holes are punched on the floor of the carriage according to the positions of the oil pipe 22, the exhaust gas exhaust pipe 17 and the combustion air supply pipe 11, and the oil pipe 22, the exhaust gas exhaust pipe 17 and the combustion air supply pipe 11 are connected to the outside air through an extended hose. The device is installed on the floor inside the carriage through a screw base 25, and the oil pipe 22 is connected to the oil pump. When the interior of the carriage starts to be heated, the first motor 6, the second motor 13 and the air heating pipe 15 are controlled to operate. The first motor 6 drives the first turbofan 7 to rotate, and air is drawn in from the air inlet pipe 3. At the same time, the second motor 1 3 drives the second turbofan 14 to rotate, drawing air from outside the vehicle into the air intake chamber 21 inside the first combustion chamber 8, effectively increasing the intake volume and ensuring the combustion-supporting effect. The air is evenly input into the combustion chamber 20 of the first combustion chamber 8 through the diversion hole 19 on the partition 18. In the process of the air passing through the combustion air supply pipe 11 and entering the combustion chamber 20, the air can be heated by the air heating pipe 15, so that the temperature of the air entering the combustion chamber 20 of the first combustion chamber 8 is increased, thereby increasing the kinetic energy of the oxygen molecules, enabling them to mix more effectively with the fuel and participate in the combustion reaction, which helps to improve the completeness of combustion. The oil is pumped into the oil pump by the oil pump. The oil is evenly sprayed into the combustion chamber 20 after being atomized by the atomizing nozzle 23 and mixed with oxygen in the air. At the same time, the igniter 24 starts to ignite, causing the oil mist to start burning. The burned gas is transported to the air inlet chamber 21 of the second combustion chamber 9 through the intermediate delivery pipe 16, and is input into the combustion chamber 20 of the second combustion chamber 9 through the diverter hole 19 on the partition 18. The remaining combustible material is ignited again by the igniter 24 in the second combustion chamber 9, so that the oil can be fully burned and utilized. The exhaust gas is discharged to the outside of the car through the exhaust gas exhaust pipe 17. The two-stage combustion chamber arrangement of the first combustion chamber 8 and the second combustion chamber 9 makes The fuel is fully burned and utilized, releasing more heat energy, meeting the demand for full combustion of fuel under plateau conditions and improving heating efficiency. The heat generated by combustion inside the first combustion chamber 8 and the second combustion chamber 9 is transferred to the air flow flowing through the outside of the first combustion chamber 8 and the second combustion chamber 9 through the heat exchange plate 10, and is discharged into the car through the air outlet pipe 4 to heat the air inside the car. In summary, this device can meet the demand for full combustion of fuel under plateau conditions, and with the function of being able to transport a large amount of air to the combustion chamber and heat the air, it further improves the combustion efficiency of the fuel and is suitable for use in working vehicles, trucks, etc. in plateau areas.
