Description

Technical Field

[0001] This utility model belongs to the field of vehicle technology, and specifically relates to a heater oil supply structure and conduit device. Background Technology

[0002] With the continuous development of the automotive industry, vehicles are increasingly used globally, especially in cold climates where their performance and reliability face severe challenges. In low-temperature environments, the physical properties of fuel change significantly, such as increased viscosity and reduced fluidity. This directly affects the normal operation of the fuel system and the engine's starting efficiency. Traditional fuel supply systems often cannot effectively cope with this low-temperature challenge, leading to difficulties in cold starts, or even failure to start, severely impacting user experience and vehicle safety.

[0003] Furthermore, fuel supply issues in low-temperature environments bring a series of negative effects. Due to the poor flowability of fuel, the fuel pump needs to consume more energy during the fuel intake process, which not only increases fuel consumption but may also lead to premature wear of the fuel pump. Simultaneously, insufficient fuel supply affects engine combustion efficiency, leading to worsened exhaust emissions and increased environmental pollution. More seriously, if the fuel system operates unstablely at low temperatures for extended periods, it may cause engine malfunctions such as cylinder wear and piston ring seizure, further shortening the vehicle's lifespan.

[0004] To address these issues, researchers and engineers have been exploring various solutions. One effective approach is to introduce a heating device into the fuel system to improve fuel flow and combustion efficiency by heating the fuel. However, existing heater-based fuel supply systems often suffer from uneven heating, high energy consumption, and complex installation, making it difficult to meet the needs of vehicles operating under different climatic conditions. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a heater oil supply structure and conduit device, which solves the problems of uneven heating, high energy consumption and complicated installation that often exist in existing heater oil supply structures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heater oil supply structure and conduit device, comprising an outer shell, quick-connect connectors at both ends of the outer shell, quick-connect connectors connecting quick-connect connectors to quick-connect connectors via sanitary clamps, multiple inner tubes fixed to the inner side of the outer shell, inner partitions connected to both ends of the inner wall of the outer shell, a heating tube and multiple outer tubes connected between two inner partitions, the outer tubes being fitted onto the outer side of the inner tubes and a heating cavity being formed between the outer tubes and the inner tubes, the heating cavity penetrating both ends of the inner partitions, a temperature sensor installed on the inner side of quick-connect connectors, the temperature sensor being electrically connected to a temperature controller.

[0007] The beneficial effects of this utility model are: fuel can quickly and evenly transfer heat to the outer tube body as it passes through the heating chamber with a small thickness, achieving safe, fast and uniform heating; multiple outer tube bodies arranged circumferentially around the heating tube can be uniformly heated.

[0008] To ensure uniform heating of the fuel within the heating chamber;

[0009] As a further improvement to the above technical solution: the heating cavity is an annular cavity structure, and the axis of the heating cavity is collinear with the axes of the inner tube and the outer tube.

[0010] The beneficial effect of this improvement is that the fuel can come into uniform contact with the inner wall of the heating chamber during the flow of fuel in the heating chamber, thus achieving uniform heating.

[0011] To prevent the heat of the fuel from being lost through the inner tube;

[0012] As a further improvement to the above technical solution: the inner tube is a circular tube structure, and the interior of the inner tube is filled with heat insulation cotton.

[0013] The beneficial effects of this improvement are: the heat insulation cotton filled inside the inner tube plays a role in heat insulation and heat preservation, preventing the heat of the fuel from being lost through the transfer of heat through the inner tube.

[0014] To ensure that the heat from the heating element is safely and stably transferred to the outer tube;

[0015] As a further improvement to the above technical solution: the cavity formed between the two inner partitions and the outer shell is filled with thermally conductive silicone oil.

[0016] The beneficial effect of this improvement is that the thermally conductive silicone oil can safely and stably heat the outer tube body through an oil bath after being heated by the heating tube.

[0017] To ensure uniform heating of the multiple outer tubes;

[0018] As a further improvement to the above technical solution: multiple outer tubes are arranged at equal intervals around the axis of the heating tube.

[0019] The beneficial effect of this improvement is that multiple outer tubes arranged at equal intervals around the circumference can be uniformly heated by the heating tubes.

[0020] To reduce the resistance encountered by the fuel as it flows within the device;

[0021] As a further improvement to the above technical solution: the two ends of the outer shell have a gradually tapering diameter structure towards the quick-connect joint, and the axis of the heating cavity is parallel to the axis of the outer shell.

[0022] The beneficial effect of this improvement is that during the flow of fuel within the outer casing, it is guided by the variable diameter structure formed at both ends of the outer casing, thereby effectively reducing the resistance when entering the heating chamber.

[0023] In order to achieve automatic control of oil temperature heating;

[0024] As a further improvement to the above technical solution: the temperature controller is electrically connected to the heating element.

[0025] The beneficial effects of this improvement are as follows: the temperature sensor monitors the temperature of the oil and feeds it back to the thermostat. When the fuel temperature is lower than the set threshold, the thermostat controls the heating element to be powered on for heating.

[0026] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0032] Example 1:

[0033] like Figure 1As shown in Figure 3: A heater oil supply structure and conduit device includes an outer shell 1. Quick-connect couplings 2 are provided at both ends of the outer shell 1. The quick-connect couplings 2 are connected to quick-connect couplings 4 via sanitary clamps 3. Multiple inner tubes 5 are fixed to the inner side of the outer shell 1. Inner partitions 6 are connected to both ends of the inner wall of the outer shell 1. A heating tube 9 and multiple outer tubes 7 are connected between two inner partitions 6. The outer tubes 7 are fitted onto the outside of the inner tubes 5, and a heating cavity 8 is formed between the outer tubes 7 and the inner tubes 5. The heating cavity 8 penetrates the inner partitions. Temperature sensors 10 are installed on the inner side of the quick-connect connector 2 at both ends of 6. The temperature sensors 10 are electrically connected to the thermostat 11. Fuel can quickly and evenly transfer heat to the outer tube 7 as it passes through the thinner heating chamber 8, achieving safe and rapid uniform heating. Multiple outer tubes 7 arranged circumferentially around the heating tube 9 can be uniformly heated. The heating chamber 8 has an annular cavity structure, and the axis of the heating chamber 8 is collinear with the axes of the inner tube 5 and the outer tube 7. As fuel flows within the heating chamber 8, it can be evenly heated. Uniform heating is achieved through contact with the inner wall of the heating tube 8. The inner tube 5 is a circular tube structure and is filled with heat-insulating cotton. The heat-insulating cotton inside the inner tube 5 serves to insulate and prevent the heat of the fuel from being lost through the transfer of heat through the inner tube 5. The cavity formed between the two inner partitions 6 and the outer shell 1 is filled with thermally conductive silicone oil. After being heated by the heating tube 9, the thermally conductive silicone oil can safely and stably heat the outer tube 7 through an oil bath. Multiple outer tubes 7 are equidistantly spaced around the axis of the heating tube 9. Multiple outer tubes 7 can be uniformly heated by heating tubes 9. The two ends of the outer shell 1 have a gradually tapering diameter structure towards the quick-connect connector 2. The axis of the heating chamber 8 is parallel to the axis of the outer shell 1. During the flow of fuel in the outer shell 1, it is guided by the tapering structure formed at both ends of the outer shell 1, thereby effectively reducing the resistance when entering the heating chamber 8. The temperature sensor 10 monitors the temperature of the fuel and feeds it back to the temperature controller 11. When the fuel temperature is lower than the set threshold, the temperature controller 11 controls the heating tubes 9 to be powered on for heating.

[0034] The working principle of this technical solution is as follows: a high-pressure oil pipe is used to connect the quick-connect connector 4 at one end of the outer shell 1 to the fuel tank, and another high-pressure oil pipe is used to connect the quick-connect connector 4 at the other end of the outer shell 1 to the engine fuel injector. The thermostat 11 is connected to the vehicle power supply. After the fuel enters the interior of the outer shell 1, it flows into the heating chamber 8 and then enters the engine fuel injector. The temperature sensor 10 monitors the temperature of the fuel and feeds it back to the thermostat 11. When the fuel temperature is lower than the set threshold, the thermostat 11 controls the heating tube 9 to be powered on. The heating tube 9 heats the thermally conductive silicone oil in the cavity formed between the two inner partitions 6 and the outer shell 1. The thermally conductive silicone oil and the outer tube 7 generate heat transfer, which raises the temperature of the outer tube 7, thereby rapidly and evenly heating the fuel in the heating chamber 8.
