[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.
[0028] The following is for reference. Figures 1-5 A muffler assembly 100 according to an embodiment of the present invention is described, which is applied in a vehicle, such as an engine 60.
[0029] like Figures 1-3 As shown, the muffler assembly 100 according to the present invention includes: a muffler 10 and a heat exchanger 20. The muffler 10 is provided with a muffler cavity, and the heat exchanger 20 is disposed in the muffler cavity. The heat exchanger 20 is provided with a liquid inlet and a liquid outlet, and the liquid inlet is located below the liquid outlet.
[0030] Understandably, the muffler 10 and the heat exchanger 20 constitute the main structure of the muffler assembly 100. The muffler 10 can attract and reduce noise from adjacent components, thereby reducing the noise of adjacent components and improving the driving experience for passengers. The heat exchanger 20 is located inside the muffler 10, which protects the heat exchanger 20 and extends its service life. For example, the adjacent components of the muffler 10 can be one of the following: engine 60, transmission, turbocharging system, turbocharged air cooling system, or EGR heat recovery system.
[0031] The muffler 10 is equipped with a muffler cavity, which provides an installation position for the heat exchanger 20. This allows the heat exchanger 20 to be installed inside the muffler 10. When the coolant passes through the heat exchanger 20, it cools and dissipates the exhaust gas entering the muffler 10, thereby reducing the heat generated by the exhaust gas from the engine 60.
[0032] In addition, the heat exchange member 20 is provided with an inlet and an outlet at two ends, and the inlet is located below the outlet. In this way, the cooling liquid can flow into the heat exchange member 20 through the inlet, so that the cooling liquid can radiate and cool the high-temperature exhaust gas, and the heated cooling liquid flows out of the outlet, so that the heat can be discharged, and the high-temperature air converted from the cooling liquid is also discharged. In this way, the high-temperature medium can be prevented from remaining in the heat exchange member 20, so that the heat exchange efficiency of the heat exchange member 20 can be improved, and the probability of boiling heat transfer can be reduced.
[0033] Therefore, by providing the muffler cavity in the muffler 10, the heat exchange member 20 can be arranged in the muffler cavity. The cooling liquid flows into the heat exchange member 20 through the inlet, so that the cooling liquid can cool the muffler 10, thereby ensuring the use performance of the muffler 10. The cooling liquid carries away the high temperature from the outlet, and the heat of the cooling liquid is transferred to the cab, thereby saving the energy consumption of the vehicle, and further saving the cost.
[0034] As shown in Figure 3 , the heat exchange member 20 comprises a plurality of bending segments 21 connected in sequence. That is, the plurality of bending segments 21 are connected in sequence to form the main body of the heat exchange member 20. The cooling liquid flows into the plurality of bending segments 21 from the inlet. In this way, the heat exchange area of the cooling liquid and the high-temperature exhaust gas can be improved, so that the cooling efficiency of the high-temperature exhaust gas can be improved. The plurality of bending segments 21 can increase the flow resistance of the cooling liquid. In this way, the flow rate of the cooling liquid can be reduced, so that there is sufficient heat exchange area and time between the cooling liquid and the high-temperature exhaust gas, thereby further improving the cooling efficiency of the heat exchange member 20 to the high-temperature exhaust gas. For example, the plurality of bending segments 21 occupy 70% of the internal space of the muffler cavity. In this way, the cooling area of the heat exchange member 20 to the high-temperature exhaust gas can be increased, thereby preventing the heat damage of the engine 60.
[0035] In particular, as shown in Figure 3 , the plurality of bending segments 21 extend in the vertical direction, or the plurality of bending segments 21 extend in the horizontal direction. It can be understood that part of the plurality of bending segments 21 extends vertically, and part of the plurality of bending segments 21 extends horizontally. In this way, the vertically extending part can avoid the exhaust port of the engine 60, so that the muffler 10 can be arranged on one side of the engine 60, thereby cooling and radiating the high-temperature exhaust gas of the engine 60 by the heat exchange member 20.
[0036] In addition, as shown in Figures 1-3As shown, the muffler 10 comprises a main shell 11 and a side shell 12, the heat exchange element 20 is arranged in the main shell 11, the side shell 12 is arranged on one side of the main shell 11, and the side shell 12 is arranged in close contact with the heat exchange element 20. That is, the main shell 11 and the side shell 12 constitute the main structure of the muffler 10, the main shell 11 and the side shell 12 are arranged opposite to each other, so that the muffling cavity can be formed between the main shell 11 and the side shell 12, and the heat exchanger can be arranged inside the main shell 11 and the side shell 12. Moreover, the side shell 12 and the heat exchange element 20 are arranged in close contact, so that after the heat exchange element 20 is installed in the muffling cavity, the side shell 12 covers the main shell 11 and the heat exchange element 20, so that the side shell 12 can protect the heat exchange element 20. The side shell 12 can also act as a heat insulation layer between the heat exchange element 20 and the air, so that the muffler 10 can prevent the heat damage of high-temperature exhaust gas, thereby reducing the arrangement of surrounding heat insulation plates, heat insulation cotton or other heat insulation measures, and saving costs.
[0037] In addition, as shown in Figures 1-3 The muffler assembly 100 further comprises a catalyst 30 connected to the upper end of the main shell 11, and the catalyst 30 is in communication with the muffling cavity. It can be understood that the catalyst 30 is located on the upper side of the main shell 11, so that the catalyst 30 can convert harmful gases of high-temperature exhaust gas into harmless gases, and the catalyst 30 is in communication with the muffling cavity, so that the high-temperature exhaust gas purified by the catalyst 30 can enter the muffling cavity for cooling and heat dissipation, thereby realizing the cooling and heat dissipation of the high-temperature exhaust gas.
[0038] As shown in Figures 1-3 The upper part of the catalyst 30 is provided with an air inlet 31, and the lower part of the main shell 11 is provided with an air outlet 32, and the air inlet 31 and the air outlet 32 are in communication with the muffling cavity. That is, the upper end of the catalyst 30 is provided with the air inlet 31, and the lower part of the main shell 11 is provided with the air outlet 32, the exhaust gas of the engine 60 enters the catalyst 30 from the air inlet 31, and the exhaust gas is oxidized and reduced in the catalyst 30, thereby reducing the content of harmful substances in the exhaust gas. The exhaust gas enters the heat exchange element 20 from the catalyst 30, the heat exchange element 20 cools and heats the exhaust gas, and the low-temperature exhaust gas is discharged from the air outlet 32. This arrangement can improve the integration of the muffler 10, thereby omitting the arrangement of the exhaust pipe, and optimizing the vehicle space and saving costs.
[0039] The heat management system according to the present application comprises: an engine 60 and the muffler assembly 100 of the above embodiment, the engine 60 is provided with an exhaust port, the muffler assembly 100 is arranged on the engine 60, and the muffler assembly 100 is provided with the air inlet 31 which is communicated with the exhaust port. By arranging the sound attenuation cavity in the muffler 10, the heat exchange element 20 is arranged in the sound attenuation cavity, the cooling liquid flows into the heat exchange element 20 through the liquid inlet, so that the cooling liquid can cool the muffler 10, thereby guaranteeing the use performance of the muffler 10, the cooling liquid takes away the high temperature from the liquid outlet, and the heat of the cooling liquid is transferred to the cab, so that the energy consumption of the vehicle can be saved, and the cost can be saved.
[0040] In addition, as shown in Figure 4 , the heat management system further comprises: a heater core 40 which is selectively communicated with the liquid outlet. It can be understood that the liquid outlet can be connected with the heater core 40, and the cooling liquid has high temperature after radiating the high-temperature exhaust gas, and the cooling liquid itself also has high temperature after heat transfer. In the warm-up working condition or cold climate, the engine cooling system is in a small circulation mode, and the cooling liquid with high temperature can quickly warm up the engine 60, so that the warm-up time of the engine 60 can be reduced, the oil temperature can be improved, the viscosity of the oil can be reduced, the movement resistance of each moving mechanism can be reduced, and the lubrication condition can be improved. In this way, the effective power of the engine 60 is improved, and the service life of the engine 60 is prolonged. Moreover, the cooling liquid with high temperature is transported to the heater core 40, and the heater core 40 increases the temperature in the cab, so that the energy consumption of the vehicle can be saved, and the cost can be saved.
[0041] In addition, as shown in Figure 5 , the heat management system further comprises: a radiator 50 which is selectively communicated with the liquid outlet. That is, the liquid outlet can be connected with the radiator 50, and the cooling liquid has high temperature after radiating the high-temperature exhaust gas, and the cooling liquid itself also has high temperature after heat transfer. When the temperature of the cooling liquid reaches a preset value, the radiator 50 radiates the cooling liquid, so that the heat of the cooling liquid can be dissipated to the air, and the use performance of the heat exchange element 20 can be improved.
[0042] The vehicle according to the present application comprises the heat management system of the above embodiment. By arranging the sound attenuation cavity in the muffler 10, the heat exchange element 20 is arranged in the sound attenuation cavity, the cooling liquid flows into the heat exchange element 20 through the liquid inlet, so that the cooling liquid can cool the muffler 10, thereby guaranteeing the use performance of the muffler 10, the cooling liquid takes away the high temperature from the liquid outlet, and the heat of the cooling liquid is transferred to the cab, so that the energy consumption of the vehicle can be saved, and the cost can be saved.
