[0030] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0031] Reference below Figure 1-Figure 3 A cooler 1 according to an embodiment of the utility model is described. The cooler 1 can be applied to an exhaust gas cooling and recirculation system of an engine 2, and is mainly used for cooling the exhaust gas in the cylinder of the engine 2 to achieve exhaust gas recirculation.

[0032] like Figure 1 and Figure 2As shown, the cooler 1 according to the embodiment of the utility model comprises: a main body 10 and an air intake 20. The main body 10 is the main body 10 of the cooler 1, and the exhaust gas in the cylinder of the engine 2 can be cooled in the main body 10, and then the exhaust gas returns to the cylinder of the engine 2 after being cooled. The air intake 20 is a structural part for air intake, and the exhaust gas in the cylinder of the engine 2 can enter the main body 10 through the air intake 20, so as to be cooled.

[0033] like Figure 1 and Figure 2 As shown, the main body 10 has an intake side 11 and an outlet side 12 arranged opposite to each other, and the intake part 20 is connected to the intake side 11 of the main body 10. The intake side 11 is the side of the main body 10 where air is taken in, and the outlet side is the side of the main body 10 where air is discharged, and the intake side 11 and the outlet side are respectively located on opposite sides of the main body 10. The intake part 20 is connected to the intake side 11 of the main body 10. This arrangement is reasonable, and the exhaust gas in the cylinder of the engine 2 can enter the main body 10 from the intake side 11 through the intake part 20, and be discharged from the outlet side 12 on the opposite side after cooling, and then enter the cylinder of the engine 2.

[0034] like Figure 1 and Figure 2 As shown, the main body 10 is arranged to be tilted upward in the direction from the air intake side 11 to the air outlet side 12. That is to say, the exhaust gas in the cylinder of the engine 2 moves in the main body 10 in an inclined upward direction. It should be noted that since the exhaust gas is heat exchanged with the coolant in the main body 10, the exhaust gas temperature is reduced, and condensed water is generated in the main body 10. The main body 10 is arranged tilted, the air intake side 11 of the main body 10 is lower than the air outlet side of the main body 10, and the air intake part 20 is connected to the air intake side 11 of the main body 10, that is, the air intake part 20 is connected to the lowest point of the main body 10. The condensed water can flow into the air intake part 20 through the main body 10, and finally be discharged from the air intake part 20, so that the local accumulation of condensed water in the main body 10 can be avoided, and the cooler 1 can be further prevented from being corroded by the condensed water.

[0035] Therefore, by arranging the main body 10 at an angle, the air inlet side 11 of the main body 10 is lower than the air outlet side of the main body 10, and at the same time the air inlet 20 is connected to the air inlet side 11 of the main body 10, that is, the air inlet 20 is connected to the lowest point of the main body 10, condensed water can flow into the air inlet 20 through the main body 10, and finally be discharged from the air inlet 20. In this way, the condensed water in the cooler 1 can be treated without adding additional devices, space and control logic, thereby avoiding the accumulation of condensed water in the cooler 1, thereby causing corrosion to the control valve 120 and the cooler 1.

[0036] Among them, the main body 10 forms an angle α with the horizontal plane, and the value range of α is: 5°≤α≤90°. Since the main body 10 is tilted, an angle is formed between the main body 10 and the horizontal plane. However, the angle α between the main body 10 and the horizontal plane needs to be within a reasonable range, and the angle α cannot be too small, that is, less than 5°. In this way, the inclination of the main body 10 is too small, which is not conducive to the discharge of condensed water in the cooler 1, and it is easy to cause the accumulation of condensed water in the cooler 1, causing corrosion to the cooler 1. Of course, the angle α cannot be greater than 90°, which will cause the air inlet side 11 of the main body 10 to be higher than the air outlet side of the main body 10. An inclined or vertical angle is formed between the main body 10 and the horizontal plane.

[0037] In addition, if Figure 1 and Figure 2 As shown, the cooler 1 also includes: an air outlet portion 30, which is connected to the air outlet side of the main body 10. The air outlet portion 30 is a structural member for air outlet, and the air outlet portion 30 is connected to the air outlet side 12 of the main body 10. This arrangement is reasonable, and the exhaust gas in the cylinder of the engine 2 is cooled in the main body 10 and then flows to the air outlet side 12, and then can be discharged from the air outlet portion 30, and finally enter the cylinder of the engine 2, completing the exhaust gas cooling cycle of the engine 2.

[0038] Of course, if Figure 1 and Figure 2 As shown, the cooler 1 further includes: a liquid inlet portion 40 and a liquid outlet portion 50 , wherein the liquid inlet portion 40 is disposed between the main body 10 and the air inlet portion 20 , and the liquid outlet portion 50 is disposed between the main body 10 and the air outlet portion 30 . The liquid inlet 40 is mainly used for the entry of coolant, and the liquid outlet 50 is mainly used for the outflow of coolant. The liquid inlet 40 is arranged between the main body 10 and the air inlet 20, and the liquid outlet 50 is arranged between the main body 10 and the air outlet 30. It should be noted that the liquid inlet 40 is connected with one side of the water outlet of the engine 2 through a hose, and the liquid outlet 50 is connected with one side of the water inlet of the engine 2 through a hose. A steel belt-type elastic hoop is fixed at the connection between the hose and the liquid inlet 40 and the liquid outlet 50 to ensure the sealing of the connection. Specifically, the water on one side of the water outlet of the engine 2 partially enters the main body 10 from the liquid inlet 40, and then flows into the engine 2 through the water inlet of the engine 2 from the liquid outlet 50. Through the flow of the coolant of the engine 2, a cooling circuit of the cooler 1 of the exhaust gas recirculation system is formed.

[0039] Furthermore, if Figure 1 and Figure 2As shown, the cooler 1 further includes: a first connection part 60 and a second connection part 70, the first connection part 60 is connected between the main body 10 and the air inlet 20, the liquid inlet 40 is arranged below the first connection part 60, the second connection part 70 is connected between the main body 10 and the air outlet 30, and the liquid outlet 50 is arranged above the second connection part 70. The first connection part 60 and the second connection part 70 can both play the role of intermediate connection, connecting the first connection part 60 between the main body 10 and the air inlet 20, and the second connection part 70 between the main body 10 and the air outlet 30, so that the first connection part 60 can connect the main body 10 and the air inlet 20, and the second connection part 70 can connect the main body 10 and the air outlet 30, and the liquid inlet 40 is arranged below the first connection part 60, and the liquid outlet 50 is arranged above the second connection part 70. 0, it can be understood that since the first connecting portion 60 is arranged close to the air inlet portion 20 and the second connecting portion 70 is arranged close to the air outlet portion 30, the liquid inlet portion 40 is arranged close to the air inlet portion 20, and the liquid outlet portion 50 is arranged close to the air outlet portion 30, and the liquid inlet portion 40 is located below the liquid outlet portion 50 as a whole, so that the coolant flows from bottom to top, so that the coolant can fully flow through the main body 10, the exhaust gas can better exchange heat with the coolant in the main body 10, and then the cooling effect of the exhaust gas can be improved.

[0040] In addition, Figure 1 and Figure 2 As shown, the cooler 1 further includes: a first mounting portion 100 and a second mounting portion 110. The first mounting portion 100 is arranged on the main body 10, and the first mounting portion 100 is suitable for fixing with the cylinder head of the engine 2. The second mounting portion 110 is arranged on the air intake portion 20, and the second mounting portion 110 is suitable for fixing with the cylinder body of the engine 2. The first mounting portion 100 and the second mounting portion 110 can both play the role of installation and fixing. The first mounting portion 100 is arranged on the main body 10, and the second mounting portion 110 is arranged on the air intake portion 20. In this way, the main body 10 can be fixed to the cylinder head of the engine 2 through the first mounting portion 100, and the air intake portion 20 can be fixed to the cylinder body of the engine 2 through the second mounting portion 110. In this way, the cooler 1 as a whole can be more firmly arranged on the engine 2.

[0041] like Figure 3 As shown, the engine 2 according to the embodiment of the utility model comprises: a catalyst and the cooler 1 described in the above embodiment, and the air intake 20 is connected to the catalyst. It should be noted that the air intake 20 is connected to the catalyst after the supercharger turbine, and a part of the exhaust gas is separated from the catalyst to enter the exhaust gas recirculation system. Moreover, a filter gasket is provided at the connection between the air intake 20 and the catalyst. The filter gasket can be a gasket with a filter screen, so that the sealing of the connection between the air intake 20 and the catalyst can be ensured, and at the same time, it can play a role in preliminary filtering of exhaust gas impurities.

[0042] In addition, if Figure 3 As shown, the engine 2 also includes: a control valve 120, and the air outlet 30 is connected to the control valve 120. The control valve 120 can play a control role. One end of the control valve 120 can be connected to the air inlet of the supercharger compressor through a hose. The connection between the hose and the control valve 120 can be fixed by a steel belt type elastic hoop to ensure the sealing of the connection. The air outlet 30 is connected to the control valve 120, so that the amount of exhaust gas discharged from the air outlet 30 can be adjusted by adjusting the opening of the control valve 120, thereby adjusting the amount of exhaust gas entering the exhaust gas recirculation system. Of course, a sealing gasket is provided at the connection between the air outlet 30 and the control valve 120, so that the sealing of the connection between the air outlet 30 and the control valve 120 can be ensured, thereby preventing the exhaust gas from leaking.

[0043] According to an optional embodiment of the present utility model, Figure 1-Figure 3 As shown, the engine 2 also includes: a pressure difference sensor 130, and the cooler 1 also includes: an upstream interface 90, which is arranged at the air outlet 30, and the upstream interface 90 is suitable for communicating with the upstream of the pressure difference sensor 130, and the outlet end of the control valve 120 is provided with a downstream interface 121, and the downstream interface 121 is connected with the downstream of the pressure difference sensor 130. The differential pressure sensor 130 can detect the pressure difference between the two ends. Specifically, an upstream interface 90 is provided above the air outlet 30. One end of the hose is connected to the upstream interface 90, and the other end is connected to the upstream of the differential pressure sensor 130. Steel belt-type elastic ring hoops are provided at the connection of the two ends of the hose to ensure the sealing of the connection. A downstream interface 121 is provided at the outlet end of the control valve 120. One end of the hose is connected to the downstream interface 121, and the other end is connected to the downstream of the differential pressure sensor 130. Steel belt-type elastic ring hoops are also provided at the connection of the two ends of the hose to ensure the sealing of the connection. The differential pressure sensor 130 monitors the pressure difference between the exhaust gas entering the cooler 1 and the exhaust gas after passing through the control valve 120, thereby adjusting the opening of the control valve 120, and then adjusting the amount of exhaust gas entering the exhaust gas recirculation system to ensure the normal operation of the engine 2. The differential pressure sensor 130 can be an exhaust gas particle differential pressure sensor 130.

[0044] Furthermore, if Figure 1-Figure 3As shown, the cooler 1 further includes: a temperature interface 80, which is arranged at the air outlet 30, and is suitable for communicating with a temperature sensor 160.
