Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile machinery, in particular to a fuel heating device and a vehicle with the fuel heating device. Background Art
[0002] When a vehicle is in a low-temperature environment, the fuel in the fuel tank will partially wax or even freeze completely, blocking the filter screen, filter paper and other parts in the oil pipeline, often causing the vehicle to be unable to start and run normally. Therefore, it is necessary to insert a fuel heating device into the fuel tank. After power is turned on, the heating rod of the heating device begins to heat the fuel, so that the fuel melts and can pass through the fuel filter element normally and be sucked into the engine. However, in the existing technology, the heating rod is inserted into part of the fuel. After the fuel heats up and melts, the melted part of the diesel is sucked into the engine, but the fuel away from the heating rod is still in a frozen state, resulting in a cavity near the heating rod. The heating rod cannot contact the frozen fuel in other parts of the fuel tank and cannot continue to heat the fuel. There are problems such as uneven heating of the fuel tank and too low heating efficiency. Utility Model Content

[0021] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the description of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are also within the scope of protection of the present invention.
[0022] like Figure 1 As shown, an embodiment of one aspect of the present application provides a fuel heating device, including a heating rod 1 for heating and melting fuel installed in a fuel tank 7; the fuel heating device also includes a power device and a fluid circulation drive member, the power device being in transmission connection with the fluid circulation drive member, and being used to drive the fluid circulation drive member to rotate to drive the fuel melted by the heating rod 1 to flow. In this embodiment, the power device can preferably be an oil pump motor, and the fluid circulation drive member can preferably be an impeller 3. In the following embodiments, the oil pump motor is used as the power device, and the impeller 3 is used as the fluid circulation drive member. In a further embodiment, the power device also includes a drive rod 2, which is used to drive the fluid circulation drive member to rotate and is installed inside the heating rod 1.
[0023] The fuel heating device provided in the present application is in the shape of a long tube, including a heating rod 1, a heating power supply, an oil pumping motor, a driving rod 2, an impeller 3 and a protective shell 4. The heating rod 1 is used to heat and melt fuel frozen in a low-temperature state. It is installed in the fuel tank 7 of the vehicle 10 and is a hollow long tube; the oil pumping motor is used to drive the impeller 3 to rotate and pump out the melted fuel. The oil pumping motor and the driving rod 2 are both installed inside the heating rod 1; the impeller 3 is connected to the driving rod 2 and is arranged at the end of the heating rod 1. The protective shell 4 is covered on the outside of the impeller 3 and is fixedly connected to the driving rod 2 for protecting and further fixing the impeller 3. The oil pump motor and heater rod 1 share a heating power source. Heating rod 1 starts first, melting the cold fuel near it. The oil pump motor is set to start three minutes after heating rod 1. Three minutes later, the oil pump motor, via drive rod 2, drives impeller 3 to rotate, mixing some of the melted fuel with the cold fuel, creating a circulation flow and accelerating heat exchange between the melted and cold fuels. This allows the fuel tank 7 to be heated more evenly, allowing frozen fuel away from the heater rod to be heated and melted by the heated fuel, thus avoiding the formation of "cavities" and improving heating efficiency. Furthermore, the oil pump motor can also draw some of the melted fuel from the bottom end of heater rod 1 and pump it out to engine 9 through vehicle 10's fuel inlet pipe 8. In further embodiments, the oil pump motor can be replaced with a gear pump, jet pump, or other type of electric pump; and the heating power source can also be replaced with an onboard power supply or other form of external power supply.
[0024] The fuel heating device also includes a filter cartridge 5 and an oil level sensor 6. The filter cartridge 5 is positioned at one end of the heating rod 1 in the fuel tank 7. The oil level sensor 6 is mounted on top of the heating rod 1 to sense the fuel level and ensure the heating device is positioned accurately to fully melt the fuel. The filter cartridge 5 is used to filter out large scum in the fuel tank, preventing the suction pipe from clogging and preventing fuel from being drawn. It is mounted inside the heating rod 1 to ensure that the melted fuel can be properly drawn into the engine. In further embodiments, the filter cartridge 5 can be mounted externally to the heating rod 1.
[0025] The fuel heating device also includes a temperature control chip, which is connected to the sensor and the heating power supply. This chip is used to adjust the power of the heating power supply based on the oil temperature sensed by the sensor. When the heating rod 1 is first activated, the temperature of the fuel and the heating rod 1 are both low. The temperature control chip receives the temperature signal from the sensor and, in order to quickly heat the fuel, increases the power of the heating power supply based on the sensor signal. This rapidly heats both the heating rod 1 and the fuel tank 7 to their normal temperatures.
[0026] In addition, the heating rod 1 of the fuel heating device provided in this embodiment uses a positive temperature coefficient (PTC) material. As the temperature rises, the resistance value of the heating material will continue to increase. When the temperature rises to a value close to the maximum set temperature of the material, the resistance value will increase sharply, causing the heating material to be close to a power-off state, thereby limiting the fuel temperature to within the maximum set temperature value, ensuring the safety of the vehicle 10.
[0027] This embodiment provides a fuel heating device with the following specific operating principles: Under low-temperature conditions, a heating rod 1 is connected to a heating power source. A temperature control chip receives temperature signals from a sensor and increases the heating power, accelerating the melting of the nearby low-temperature fuel by the heating rod 1. After heating for three minutes, the pumping motor activates. This pumping motor draws a portion of the melted fuel through the impeller 3 at the bottom of the heating rod 1 and pumps it out to the engine 9, where it enters and burns. Furthermore, the pumping motor, via a drive rod 2, drives the impeller 3 to rotate, mixing the remaining melted fuel with the low-temperature fuel, creating a circulating flow. This accelerates heat exchange between the melted and low-temperature fuels, resulting in more uniform heating of the fuel tank 7 and improved heating efficiency. When the temperature reaches the maximum set point, the resistance of the heating rod 1 increases dramatically, and the heating rod 1 becomes nearly de-energized, limiting the temperature to within the maximum set point until the fuel is completely melted.
[0028] In summary, the above-mentioned embodiment of the present invention provides a fuel heating device, which is equipped with a power device and a fluid circulation drive member on the basis of the heating rod 1, and the power device drives the fluid circulation drive member to rotate through the drive rod 2; the heating rod 1 first heats the fuel near it, and then the power device is started, and the power device sucks a part of the melted fuel from the bottom end of the heating rod 1 and pumps it to the engine 9, so that the fuel enters the engine 9 for combustion; the other part of the melted fuel is mixed with the surrounding low-temperature fuel under the rotation action of the fluid circulation drive member to form a circulation, and heat exchange is carried out, so that the part of the low-temperature fuel away from the heating rod 1 is quickly melted, which solves the problems of slow heating speed and uneven heating of traditional fuel heating systems.
[0029] Another embodiment of the present invention provides a vehicle 10, including a fuel tank 7, an engine 9 and the above-mentioned fuel heating device, the heating rod 1 of the fuel heating device and the fluid circulation drive are both arranged in the fuel tank 7, the engine 9 also includes a combustion chamber and an oil inlet pipe 8, one end of the oil inlet pipe 8 is connected to the combustion chamber, and the other end of the oil inlet pipe 8 extends into the fuel tank 7, enters the fuel tank 7 from the upper end of the heating rod 1, and opens above the impeller 3. The power device is powered, and the heated fuel is sucked in from the bottom end of the heating rod 1, pumped out in the combustion chamber of the engine 9 for combustion.
[0030] The heating rod 1 is installed in the fuel tank 7. Under low temperature conditions, the heating rod 1 is connected to the heating power supply and begins to heat the fuel. The temperature control chip increases the power of the heating power supply to accelerate the melting of the fuel near the heating rod 1. After the heating rod 1 is heated for 3 minutes, the power unit is started. On the one hand, the power unit draws a portion of the melted fuel from one end of the oil inlet pipe 8 at the bottom of the heating rod 1 and pumps it into the combustion chamber of the engine 9 through the oil inlet pipe 8. The melted fuel enters the combustion chamber of the engine 9 and burns. On the other hand, the power unit drives the fluid circulation drive member through the drive rod 2 to start rotating, mixing another portion of the melted fuel with the low-temperature fuel to form a circulation, accelerating the heat exchange between the melted fuel near the heating rod 1 and the low-temperature fuel away from the heating rod 1, making the fuel tank 7 heated more evenly and improving the heating efficiency, thereby solving the problems of slow heating speed and uneven heating in traditional fuel heating systems.
[0031] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
