Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle engineering, and in particular relates to an engine oil tank heating system. Background Art

[0002] In winter, as the outside temperature drops, the viscosity and density of diesel increase, and the surface tension increases. According to measurements, when the temperature drops from 40°C to -10°C, the viscosity of diesel increases by 83%, the density increases by 8%, and the 0# diesel in the tank will wax, which will cause the fluidity of diesel to deteriorate, the atomization to be poor, and the ignition lag period to be extended, resulting in poor fluidity of the oil and the engine not being able to work properly. Especially in winter, diesel engines often fail to start or break down when stopped due to waxing of diesel. If there is severe weather such as a snowstorm, it will threaten the lives of drivers and passengers.

[0003] In actual applications, drivers usually use a blowtorch or open flame to bake the fuel tank and related parts. This operation has the risk of burning the vehicle body or burning the vehicle, and will also cause damage to the fuel tank. In addition, many vehicles use engine coolant to flow through the fuel tank for heating. Manufacturers recommend using the engine body to take water, while most vehicle manufacturers separate a branch before entering the urea heating water circuit and flow through the fuel tank to heat the fuel. In this case, the coolant leaves the body and flows into the pipeline. There will be heat loss in the process. The longer the pipeline, the greater the heat loss. In addition, the coolant temperature is low when the vehicle is just started, and it takes a long time to warm up the car, affecting the user experience. In addition, the coolant heating tank pipeline valve is manual, and the driver is prone to forget to open or close it, which causes fuel consumption waste in summer and affects normal use.

[0032] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0033] The utility model relates to an engine oil tank heating system, such as Figure 1 As shown, it includes a fuel tank body 1, a vortex tube 2 and an air intake assembly; a heating tube 3 is distributed in the fuel tank body 1; the vortex tube 2 has an air intake port 16 and a hot end outlet 15; the air intake assembly is connected to the air intake port 16, and the air intake of the heating tube 3 is connected to the hot end outlet 15; the air intake assembly is used to transport gas to the air intake port 16, and the gas is divided into high-temperature gas and low-temperature gas in the vortex tube 2, and the high-temperature gas is output to the heating tube 3 through the hot end outlet 15 for heating the interior of the fuel tank body 1.

[0034] like Figure 2The figure shows the internal structure of the vortex tube 2. The vortex tube 2 is an energy splitting device that controls and reaches the required temperature and flow rate through an internal replaceable generator. The vortex tube 2 has a hot end outlet 15, a cold end outlet 14 and an air inlet port 16. The vortex tube 2 has a vortex chamber on the side opposite to the air inlet port 16. A hot end tube is arranged on one side of the vortex chamber of the vortex tube 2. A cold end tube is arranged on the other side of the vortex chamber of the vortex tube 2 in communication with the hot end tube. The hot end outlet 15 is located at the pipe mouth of the hot end tube, and the cold end outlet 14 is located at the pipe mouth of the cold end tube. A hot end valve 17 is arranged in the hot end tube to adjust the flow rate of the gas at the hot end outlet 15.

[0035] The air intake of the vortex is compressed air. The compressed air enters the vortex chamber tangentially through the air intake port 16 and the nozzle flow channel. After the vortex is generated in the vortex chamber, the vortex gas entering the hot end tube undergoes energy separation in the process of flowing to the hot end tube, and gradually separates into two streams of cold and hot. The outer layer of gas flows along the wall from the air intake port 16 toward the hot end outlet 15 of the hot end tube, and the temperature gradually increases, and finally flows out from the hot end outlet 15. The inner layer of gas flows from the hot end valve 17 to the cold end outlet 14 on the axis, and the temperature gradually decreases, and finally flows out from the cold end outlet 14. The lowest temperature of the air generated at the cold end outlet 14 can reach -46°C, and the highest temperature of the air generated at the hot end outlet 15 can reach 127°C. The high-temperature gas output through the hot end outlet 15 enters the heating tube 3 through the air inlet of the connected heating tube 3. Since the heating tube 3 is distributed inside the tank body 1, the oil inside the tank can be fully heated. The present application uses the high-temperature gas generated by the vortex tube 2 to heat the engine 4 tank, without the need to use the gas source inside the engine 4, thereby avoiding heat loss and long warm-up time caused by the gas reaching the tank from the engine 4 through a long pipeline; avoiding the traditional driver's use of open flame to bake the tank, which is easy to cause damage to the tank; being able to increase the temperature of the oil in the tank in a cold environment, so that the oil in the tank body 1 does not need to be replaced with low-temperature diesel, saving the vehicle's operating costs and avoiding the waxing of the oil under cold conditions; and the structure of the entire system is simple, avoiding the complexity of the device, reducing the warm-up time, improving the heating efficiency, achieving convenience and practicality, and enhancing the user experience.

[0036] As a preferred embodiment, the engine oil tank heating system also includes an engine 4, the circulating gas inlet of the engine 4 is connected to an intercooler 5, the circulating gas outlet of the engine 4 is connected to a supercharger 6, and the outlet end of the supercharger 6 is connected to the inlet end of the intercooler 5; the gas discharged from the circulating gas outlet of the engine 4 is discharged to the outside through the outlet end of the supercharger 6 in one way, and flows through the intercooler 5 through the outlet end of the supercharger 6 in the other way, and circulates to the circulating gas inlet of the engine 4 through the outlet end of the intercooler 5 through the outlet end of the intercooler 5.

[0037] By setting the intercooler 5 and the supercharger 6, the circulation efficiency of the gas inside the engine 4 is further enhanced. The supercharger 6 increases the intake amount entering the engine 4. The intercooler 5 can cool down the overheated gas. After the engine 4 completes the work, the gas is cooled by the intercooler 5 and enters the supercharger 6, where it can be compressed again into the engine 4 to participate in the circulation, thereby saving energy consumption and improving utilization efficiency.

[0038] As a preferred embodiment, the vortex tube 2 also has a cold end outlet 14, and the cold end outlet 14 is connected to the outlet end of the intercooler 5 through a pipeline; the low-temperature gas is output to the outlet end of the intercooler 5 through the cold end outlet 14, and is mixed with the gas output from the outlet end of the intercooler 5 and transported to the circulating gas inlet of the engine 4.

[0039] The vortex tube 2 can separate the input gas into cold and hot streams, that is, after the gas generates swirl in the vortex tube 2, energy separation will occur in the swirl gas in the process of flowing to the hot end outlet 15, and it will gradually be divided into two streams of cold and hot air. The low-temperature gas will be output from the cold end outlet 14 of the vortex tube 2 and meet the gas output from the outlet end of the intercooler 5 in the pipeline and be transported to the circulating gas inlet of the engine 4, thereby increasing the air intake of the engine 4, improving the economy and power of the whole machine, reducing energy loss, and improving recycling efficiency.

[0040] As a preferred embodiment, the air outlet of the heating tube 3 is connected to the air inlet end of the intercooler 5 through a pipeline; the gas output through the air outlet of the heating tube 3 is mixed with the gas output from the air outlet end of the supercharger 6 and enters the intercooler 5.

[0041] The high-temperature gas output from the hot end outlet 15 of the vortex tube 2 enters the heating tube 3 through the air outlet of the heating tube 3 to heat the oil in the tank body 1. The heated gas is output through the air outlet of the heating tube 3 and enters the air inlet end of the intercooler 5 through the pipeline, and is mixed with the gas output from the air outlet of the supercharger 6 and finally enters the interior of the intercooler 5 through the pipeline, so as to enter the circulating air inlet of the engine 4 through the air outlet of the intercooler 5, thereby further increasing the air intake amount of the engine 4 and improving the economy and power performance of the whole machine.

[0042] As a preferred implementation, the air inlet end of the supercharger 6 is connected to an air filter 7 , and the purified gas is delivered to the supercharger 6 through the air filter 7 .

[0043] The purpose of the supercharger 6 is to compress the air before it enters the cylinder of the engine 4 to increase the density of the air, so that more air can be filled into the cylinder, thereby increasing the power of the engine 4, and the compressed air enters the interior of the engine 4, thereby increasing the amount of air entering the engine 4. Before the air enters the supercharger 6, an air filter 7 is connected to it, the purpose of which is to filter air impurities. If the air quality is not good, for example, impurities are mixed in the air, it will accelerate the damage to the supercharger 6, the engine 4 and the corresponding connecting pipelines, and in severe cases it will affect the life of the supercharger 6 or even the engine 4. Therefore, by setting the supercharger 6 to be connected to the air filter 7, the service life of the whole machine is further improved.

[0044] As a preferred embodiment, a one-way valve 8 is connected between the cold end outlet 14 of the vortex tube 2 and the air outlet end of the intercooler 5, and the one-way valve 8 enables the gas output from the air outlet end of the intercooler 5 to flow unidirectionally to the circulating gas inlet of the engine 4.

[0045] The low-temperature gas output from the cold-end outlet 14 of the vortex tube 2 is transported to the pipeline connected to the outlet end of the intercooler 5 through a pipeline, mixed with the gas output from the outlet end of the intercooler 5 in the pipeline, and then transported to the circulating gas inlet of the engine 4 and finally enters the engine 4 to perform work. Since a one-way valve 8 is provided in the connecting pipeline of the cold-end outlet 14 of the vortex tube 2, the gas at the outlet end of the intercooler 5 will not flow back into the cold-end outlet 14 of the vortex tube 2 to avoid backflow into the vortex tube 2, thereby increasing the intake volume of the engine 4, saving energy consumption, and improving the operating efficiency of the engine 4. The low-temperature gas output from the cold-end outlet 14 of the vortex tube 2 has a certain pressure, thereby further increasing the intake volume of the engine 4, improving the power performance and economy of the whole machine, and reducing the operating cost. There is no need to use additional equipment to increase the intake volume for the engine 4, and there is no need to change the original pipeline and structure. It is easy to implement and convenient to carry out in practical applications, and has high practicality and reliability.

[0046] As a preferred embodiment, the air intake assembly includes an air compressor 9 and an air storage tank 10; the air outlet of the air storage tank 10 is connected to the air intake port 16 for storing air; the air is compressed by the air compressor 9 and transported to the air intake port 16 through the air storage tank 10.

[0047] The air compressor 9 provides an air source for the vortex tube 2; connecting the air compressor 9 to the gas tank 10 can effectively improve the efficiency of the air compressor 9. Since the gas tank 10 can provide sufficient gas storage, the air compressor 9 can be started throughout the entire process when needed, or the air compressor 9 can be started when the air pressure in the gas tank 10 is insufficient. This avoids the problem of the air compressor 9 being started multiple times and operating under low pressure, resulting in frequent starts and stops of the motor and increased wear of the equipment itself, effectively improving the working efficiency of the air compressor 9 and extending its service life.

[0048] The hot end outlet 15 of the vortex tube 2 is connected to the air inlet of the heating tube 3, and the air inlet port 16 of the vortex tube 2 is connected to the gas storage tank 10, which is connected by the air compressor 9. The air compressor 9 provides a gas source for the vortex tube 2. The high-temperature gas generated after the gas passes through the vortex tube 2 is output through the hot end outlet 15 and enters the interior of the oil tank body 1 through the air inlet of the heating tube 3 to heat the oil. Due to the action of the air compressor 9, the gas pressure entering the vortex tube 2 through the air inlet port 16 of the vortex tube 2 can be different, which further causes the gas temperature of the hot end outlet 15 of the vortex tube 2 to be different, and the two are proportional.

[0049] According to simulation estimation, for example, for common vortex tubes 2 with models VC52004S, VC52008S and VC52010S, the output gas temperature at the hot end can reach 80°C or above at an input gas pressure of 1MPa. Taking into account all usage environments, general vehicles will use 0# diesel at 8~4°C, -10# diesel at 4~-5°C, -20# diesel at -5~-14°C, -35# diesel at -14~-29°C, and -50# diesel at -29~-44°C.

[0050] As a preferred embodiment, a control valve 11 is also connected between the gas storage tank 10 and the air intake port 16, and the control valve 11 is connected to a controller 13. The opening of the control valve 11 is controlled by the controller 13 to control the amount of air intake from the gas storage tank 10 into the vortex tube 2.

[0051] When the controller 13 detects that the oil temperature signal output by the temperature sensor 12 is low, if T1=-5℃<T<T=4℃, the oil tank of the engine 4 needs to be heated, and the control valve 11 adjusts the output pressure P1 to enter the vortex tube 2 according to the signal sent by the controller 13. If T1=-14℃<T<T=-5℃, the output pressure of the control valve 11 is P2, and if T1=-29℃<T<T=-14℃, the output pressure of the control valve 11 is P3. In this way, gases with different pressures are input into the vortex tube 2, and the hot end outlet 15 outputs different and higher temperature gases, which enter the oil tank body 1 through the air inlet of the heating pipe 3, and circulate in the heating pipe 3 flowing through the oil tank body 1 to heat the diesel in the oil tank body 1.

[0052] As a preferred embodiment, the oil tank body 1 has a temperature sensor 12 inside for sensing the oil temperature inside the oil tank body 1; the controller 13 is connected to the temperature sensor 12 for controlling the opening of the control valve 11 according to the signal fed back by the temperature sensor 12.

[0053] The purpose of setting the temperature sensor 12 is to increase the temperature control of the internal oil of the tank body 1. The oil temperature is monitored by the temperature sensor 12. When the oil temperature exceeds a preset threshold, the temperature sensor 12 transmits a signal to the controller 13. The controller 13 controls the start of the air compressor 9 in the corresponding air intake assembly and the opening of the control valve 11, and outputs it to the vortex tube 2 through the air storage tank 10. The high-temperature gas in the vortex tube 2 enters the heating tube 3 to heat the oil in the tank body 1. When the oil temperature is at a specified threshold, the temperature sensor 12 transmits a signal to the controller 13, and the controller 13 controls the closing of the control valve 11 and the shutdown of the air compressor 9. The intelligence and reliability of the system are further enhanced by the setting of the temperature sensor 12 and the controller 13, and the ECU intelligent control heating mode is realized, avoiding the inconvenience caused by manual control and improving work efficiency.

[0054] As a preferred embodiment, the heating tube 3 is distributed in a spiral shape at the center of the tank body 1 along the length direction of the tank body 1; and / or the heating tube 3 is distributed in a spiral shape on the inner wall of the tank body 1 along the length direction of the tank body 1.

[0055] Preferably, the air outlet and air inlet of the heating tube 3 extend out of the fuel tank body 1 respectively, wherein the air outlet of the heating tube 3 extends toward the vortex tube 2 , and the air inlet of the heating tube 3 extends toward the air outlet end of the intercooler 5 .

[0056] In this embodiment, there may be multiple embodiments for the structural arrangement of the heating tube 3, which are not limited by the present application, and any of the following embodiments may be adopted:

[0057] Embodiment 1: The heating tube 3 is distributed in a spiral shape at the center of the fuel tank body 1 along the length direction of the fuel tank body 1 , and the heating tube 3 is distributed in a spiral shape on the inner wall of the fuel tank body 1 along the length direction of the fuel tank body 1 .

[0058] In this embodiment, the heating pipe 3 has a special structure. One end of the air inlet of the heating pipe 3 extends outside the fuel tank body 1, and one end of the air inlet of the heating pipe 3 is connected to a tee, through which three pipelines are connected, namely, an air inlet pipeline, a first air outlet pipeline and a second air outlet pipeline, wherein the air inlet pipeline extends outside the fuel tank body 1 and is connected to the pipeline where the hot end outlet 15 of the vortex tube 2 is located, the first air outlet pipeline is spirally distributed at the center of the fuel tank body 1 along the length direction of the fuel tank body 1, the second air outlet pipeline is spirally wound along the length direction of the fuel tank body 1 and connected to the inner wall of the fuel tank body 1 and then connected to the first air outlet pipeline, extending to the side of the fuel tank body 1 facing the intercooler 5, and is connected to the pipeline connected to the air inlet end of the intercooler 5 and the air outlet end of the supercharger 6 through a pipeline.
