Technical Field

[0001] The utility model belongs to the technical field of automobiles and relates to a methanol heater. Background Art

[0002] With the rapid development of my country's economy, the automobile industry, as an important pillar industry of the national economy, has achieved remarkable results. However, as the automobile industry develops rapidly, energy consumption and environmental pollution problems are becoming increasingly serious. To solve this problem, new energy vehicles have received widespread attention and are being vigorously promoted. Among them, methanol, as a renewable energy source, has the advantages of complete combustion, low emissions, and high calorific value, and has gradually become an important component of automobile fuel.

[0003] A methanol heater is a heating device designed specifically for the characteristics of methanol fuel. Its primary function is to raise the temperature of methanol fuel in low-temperature environments, allowing it to reach optimal combustion conditions and thus ensure the proper functioning of the vehicle engine. Methanol heaters have broad application prospects in the methanol vehicle sector.

[0004] The Chinese utility model patent application number 201620796228.0 discloses a water-electric integrated heater, including a heat exchanger, a combustion tube, an electric heating component, an intermediate connector, a fuel pump, an ignition coil, a controller, a motor, an intake fan wheel, an intake cover and a throttle cover. The heat exchanger consists of an inner sleeve, an outer sleeve and a positioning ring. The left end of the inner sleeve is welded with an inner plug, and the right ends of the inner sleeve and the outer sleeve are welded to the positioning ring. An interlayer with an open end is formed between the inner sleeve and the outer sleeve. A water inlet and a water outlet connected to the interlayer are provided on the upper outer wall of the heat exchanger, an exhaust port connected to the inner cavity of the inner sleeve is provided on the lower outer wall of the heat exchanger, and a plurality of heat exchange fins are welded circumferentially on the inner wall of the inner sleeve; the electric heating component is connected to the left side of the heat exchanger, and the intermediate connector and the intake cover are connected in sequence on the right side of the heat exchanger. The intake wheel fan and the throttle cover are provided in the inner sleeve of the intake cover, and the left end is provided with a throttle cover; the combustion tube is sleeved in the heat exchanger. This heater can use both fuel and electricity for heating, making it highly versatile. However, vehicles using methanol and other alcohol fuels often experience difficulty starting in low winter temperatures. Especially in northern my country, where winter temperatures are very low, methanol vehicles parked for extended periods of time can experience frost and ice forming on the fuel injectors, preventing the methanol from spraying out and preventing the vehicle from starting. Therefore, designing a methanol heater to address this issue is crucial. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The following is combined with Figure 1-4 The specific implementation methods of the present utility model are further described in detail.

[0020] In this embodiment, by Figure 1-3 As shown, the utility model includes a heat exchanger, a combustion tube 1, an intermediate connector, a fuel pump 2, an ignition coil, a controller, a motor, an air intake fan wheel, an air intake cover and a throttle cover, wherein the right end of the combustion tube 1 is connected to an end cover, and a fuel injection tube 3 is provided on the fuel pump 2. Two circulation rings 4 are fixed in the fuel injection tube 3. The two circulation rings 4 are connected through multiple air columns 5 and multiple heating tubes 6. Each heating tube 6 is provided with a heating component. Multiple heat-conducting rods 7 are fixed to the bottom of the lower circulation ring 4. A fuel injection port 8 is opened at the bottom of the fuel injection tube 3. A heat-conducting rod 9 is provided just above the fuel injection port 8. The heat-conducting rod 9 is fixed to the bottom of the multiple heat-conducting rods 7.

[0021] The heat exchanger, combustion tube 11, intermediate connector, fuel pump 2, ignition coil, controller, motor, air intake fan wheel, air intake cover, throttle cover, and the right end of the combustion tube 11 is connected to the end cover 15. The structure is the same as that of the water-electric integrated heater (heat exchanger, combustion tube 1, intermediate connector, fuel pump 2, ignition coil, controller, motor, air intake fan wheel, air intake cover and throttle cover, and the right end of the combustion tube 1 is connected to the end cover) in application number 201620796228.0, and the working principle of the above structure is as follows:

[0022] When heating fuel: After installing the heater, connect the water inlet and outlet, the fuel pump 2 inlet and outlet pipes and cables, turn on the power switch to start the heater, and the circulating water pump circulates the heat transfer medium water. The controller controls the ignition coil to spark continuously at a certain frequency. The solenoid valve on the fuel pump 2 opens, and its fuel enters the fuel injection pipe. The heating component will heat the circulation ring 4, heating pipe 6, air column 5, heat conducting rod 7 and heat conducting rod 9. After passing through the circulation ring 4, heating pipe 6 and air column 5 in the fuel injection pipe, it is ejected from the fuel injection port 8. The heat conducting rod 9 will heat the area around the fuel injection port 8 to prevent the methanol at the fuel injection port 8 from cooling and blocking the fuel injection port 8, and then mix with the air provided by the intake fan wheel to burn. After heat release and ignition, the high-temperature gas turns 180 degrees through the tail end of the flame tube and enters the gas channel between the heat exchanger and the combustion tube 1. The heat is transferred to the heat transfer medium water spirally flowing in the sealed chamber by the inner plug of the heat exchanger inner sleeve and the heat exchange fins arranged on the wall of the inner sleeve. Finally, the gas with a lowered temperature is discharged into the atmosphere through the exhaust port connected to the inner cavity of the outer sleeve. When the water temperature reaches the set temperature, the controller will control the fuel flow rate according to the signal of the water temperature sensor to reduce the heat release. When the water temperature is lower than the set value, the controller will restore the normal fuel supply of the fuel injection port 8 to achieve normal heat supply. The methanol spray is mixed with the air through the stirring component to make the mixture more uniform and burn more fully when ignited in the heater.

[0023] The operation of the first motor 10 drives the fan blades 11 to rotate, thereby driving the air flow in the circulation ring 4, the heating tube 6 and the air column 5. The electric heating wire 12 heats the internal air, and the methanol in the fuel injection cylinder 3 is heated through the circulation ring 4, the heating tube 6, the air column 5, the heat-conducting rod 7 and the heat-conducting rod 9. The heat-conducting rod 9 heats the methanol around the fuel injection port 8 to prevent the fuel injection port 8 from being blocked by methanol due to excessive cold weather.

[0024] The air flows in sequence from the upper circulation loop 4, the air column 5, the lower circulation loop 4 to the heating tube 6, and finally returns to the upper circulation loop 4, circulating in sequence.

[0025] In this embodiment, by Figure 3-4 As shown, the two circulation loops 4 are connected to the upper and lower ends of the heating tube 6 respectively.

[0026] In this embodiment, by Figure 4 As shown, the heating assembly includes a first motor 10 fixed in the heating tube 6 , a fan blade 11 is fixed to the output end of the first motor 10 , and an electric heating wire 12 is fixed in the heating tube 6 .

[0027] In this embodiment, by Figure 3-4 As shown, the gas column 5, the heating tube 6 and the heat-conducting rod 7 are all equidistantly distributed around the central axis of the heat-conducting rod 9, which can evenly heat the methanol in the fuel injection cylinder 3.

[0028] In this embodiment, by Figure 3-4 As shown, the heating tube 6 is located on the outer ring of the gas column 5.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
