Description

Technical Field

[0001] This invention relates to the field of turbocharger technology, and more specifically, to a thermal management system for a hybrid vehicle turbocharger. Background Technology

[0002] A turbocharger is part of a range extender and works in conjunction with an internal combustion engine to provide additional electrical energy to an electric vehicle, increasing its driving range.

[0003] Hybrid vehicles are primarily powered by the battery inside the hybrid system. However, in cold environments, the battery voltage drops due to the low temperature, resulting in insufficient power. In such cases, if the heat from the exhaust gases in the internal combustion engine and turbocharger can be used to heat the battery, allowing it to quickly reach a suitable operating temperature, the vehicle's power can be rapidly restored.

[0004] Therefore, it is necessary to provide a thermal management system for hybrid vehicle turbochargers to solve the above problems. Summary of the Invention

[0005] Based on the aforementioned problems in the prior art, the purpose of this application is to provide a thermal management system for a hybrid vehicle turbocharger, so as to enable the battery to quickly reach a suitable operating temperature.

An exhaust gas outlet is provided on one side of the turbocharger. The intercooler includes a cooling box, an exhaust gas pipe, and an air pipe. Both the exhaust gas pipe and the air pipe pass through the cooling box. The air pipe located inside the cooling box is wrapped around the surface of the exhaust gas pipe. A first Y-shaped pipe is connected to a pipe on one side of the cooling box. One outlet of the first Y-shaped pipe is connected to the battery. The exhaust gas outlet pipe is connected to a second Y-shaped pipe. The two outlets of the second Y-shaped pipe are respectively connected to one end of the exhaust gas pipe and the exhaust pipe.

[0007] Furthermore, the turbocharger is also provided with an exhaust gas inlet, which is connected to the exhaust port of the internal combustion engine.

[0008] Furthermore, the booster is also provided with an air inlet and an air outlet.

[0009] Furthermore, the two ends of the air duct are respectively connected to the air outlet and the internal combustion engine.

[0010] Furthermore, the other outlet of the first Y-shaped tube is an exhaust port.

[0011] Furthermore, the other end of the exhaust pipe is also connected to the exhaust pipe.

[0012] Furthermore, the air duct located inside the cooling box is spiral-shaped.

[0013] Furthermore, a reversing valve is installed inside the first Y-shaped tube.

[0014] Furthermore, a regulating valve is installed inside the second Y-shaped tube.

[0015] The beneficial effects of this invention are: by managing the heat of the turbocharger exhaust gas through the pipeline system, the battery and range extender of the hybrid vehicle can quickly reach the appropriate operating temperature in cold regions. Attached Figure Description

[0027] like Figure 1-4 As shown, this application provides a thermal management system for a hybrid vehicle turbocharger, including a turbocharger 1 and an intercooler 2.

[0028] The turbocharger 1 has an exhaust gas inlet 11 and an exhaust gas outlet 12 on one side, and an air inlet 13 and an air outlet 14 on the other side.

[0029] The intercooler 2 includes a cooling box 21, an exhaust gas pipe 22 and an air pipe 23. Both the exhaust gas pipe 22 and the air pipe 23 pass through the cooling box 21. The air pipe 23 located inside the cooling box 21 is spiral and wrapped around the surface of the exhaust gas pipe 22.

[0030] A first Y-shaped pipe 24 is connected to one side of the cooling box 21. A reversing valve is installed inside the first Y-shaped pipe 24. One outlet of the first Y-shaped pipe 24 is connected to the battery, and the other outlet of the first Y-shaped pipe 24 is the exhaust port.

[0031] The turbocharger 1's exhaust gas inlet 11 is connected to the exhaust port of the internal combustion engine, used to input the exhaust gas produced after fuel combustion in the internal combustion engine. The exhaust gas outlet 12 is connected to a second Y-shaped pipe 15, which contains a regulating valve. The two outlets of the second Y-shaped pipe 15 are respectively connected to one end of the exhaust gas pipe 22 and the exhaust pipe. The other end of the exhaust gas pipe 22 is also connected to the exhaust pipe, allowing the amount of exhaust gas, after passing through the turbocharger 1, to be regulated so that it can be discharged directly through the exhaust pipe, or after passing through the exhaust gas pipe 22 and then through the exhaust pipe.

[0032] The two ends of the air duct 23 are connected to the air outlet 14 and the internal combustion engine, respectively, so that the air pressurized by the turbocharger 1 passes through the air duct 23 and then enters the internal combustion engine for combustion.

[0033] Understandably, temperature sensors are installed in both the air duct 23 and the battery of the hybrid vehicle to detect the temperature of the compressed air and the battery.

[0034] Under normal operating conditions, the first Y-shaped pipe 24 allows the gas from the intercooler to be directly discharged, while the second Y-shaped pipe 15 directs all the exhaust gas to the exhaust pipe, preventing the exhaust gas from contacting the compressed air in the air duct 23 and thus avoiding excessively high temperatures in the compressed air within the air duct 23. Simultaneously, the intercooler 2 provides cooling airflow to the air duct 23, reducing the temperature of the compressed air and improving the combustion efficiency of the internal combustion engine.

[0035] In cold regions, if the battery temperature is normal and the range extender is running, but the compressed air temperature is low, such as when the car is first started, the overall temperature is low. Even if the compressed air is heated by the turbocharger 1, the temperature may still be too low. In this case, the intercooler 2 is turned off, and the second Y-shaped pipe 15 allows some exhaust gas to flow to the exhaust pipe. When the exhaust gas passes through the exhaust pipe 22, the air pipe 23 located inside the cooling box 21 wraps around the surface of the exhaust pipe 22, allowing the heat of the exhaust gas to be transferred to the compressed air in the air pipe 23, raising the temperature of the compressed air to ensure the fuel efficiency of the compressed air. This continues until the temperature of the compressed air becomes too high, at which point the intercooler 2 is activated again.

[0036] If the battery temperature becomes too low, the range extender and intercooler will be activated regardless of whether range extension is required. The first Y-tube 24 directs the intercooler gas towards the battery. Then, based on the temperature of the compressed air, the system controls whether exhaust gas is allowed to pass through the exhaust gas pipe 22. This allows the intercooler to blow the heat-absorbing gas towards the battery, rapidly raising the battery to a suitable temperature to ensure normal battery operation.

[0037] In the above process, as the overall temperature of the car rises, the air, when being drawn in and compressed, also begins to heat up slowly by absorbing heat from the car. At this time, by reducing the amount of exhaust gas flowing to the exhaust pipe 22 through the regulating valve inside the second Y-shaped pipe 15, the heating effect of the exhaust gas on the compressed air can be reduced. Similarly, if the intercooler 2 causes the temperature of the compressed air to drop, the amount of exhaust gas flowing to the exhaust pipe 22 can be increased to stabilize the temperature of the compressed air. This achieves the effect of controlling the temperature of the compressed air.

[0038] In summary, by managing the heat of the turbocharger 1 exhaust gas through the pipeline system, the hybrid vehicle's battery and range extender can quickly reach a suitable operating temperature in cold regions, thereby enhancing the user experience of hybrid vehicles in cold areas.
