DETAILED DESCRIPTION

[0039] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0040] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0041] As described in the background technology section, in order to improve the fuel economy of the vehicle, the exhaust gas recirculation system (EGR system) is widely used in the engine. When the EGR system is working, the collected engine exhaust gas is mixed with fresh air, and the mixed gas is further cooled through the intercooler before being delivered to the engine, wherein the ratio of the exhaust gas volume to the total gas after mixing is the EGR rate. In the process of cooling the mixed gas, the water vapor contained in the mixed gas may condense inside the intercooler to form condensed water when passing through the intercooler. The condensed water may flow into the engine cylinder from the outlet end of the intercooler under the action of gravity and airflow, affecting the combustion of the cylinder, and thus affecting the stability of the engine operation.

[0042] In the process of realizing the present invention, the applicant discovered that the greater the EGR rate, the higher the condensed water content. When the condensed water content flowing into the cylinder is high, it will not only cause poor combustion in the cylinder and misfire, but may also further damage the engine. If the condensed water content is reduced by directly reducing the EGR rate, the economy of the engine will also be reduced. Therefore, how to discharge the condensed water while ensuring a high EGR rate to ensure good fuel economy of the engine has become a problem that needs to be solved urgently.

[0043] The technical solution of the present invention is further described in detail below through specific embodiments.

[0044] According to an embodiment of the present invention, a condensate discharge system is provided, referring to Figure 1-Figure 9 The condensed water discharge system includes: a water retaining structure 10, which is arranged at the outlet end 120 of the intercooler 100 and is used to block the condensed water gathered at the outlet end 120; a water collecting structure 20, which is arranged at the bottom of the outlet end 120 and is used to accumulate the condensed water blocked by the water retaining structure 10; a first solenoid valve 30 and a water storage tank 40, which is arranged between the water collecting structure 20 and the water storage tank 40 and is used to control the selective communication between the water collecting structure 20 and the water storage tank 40 and to adjust the pressure in the water storage tank 40; the water storage tank 40 is used to store the condensed water discharged from the water collecting structure 20; a second solenoid valve 5 ... store the condensed water discharged from the water collecting structure 20; a second solenoid valve 50, which is arranged between the water collecting structure 20 and the water storage tank 40 and is used to store the condensed water discharged from the water collecting structure 20; a second solenoid valve 50, which is arranged between the water collecting structure 20 and the water storage The second solenoid valve 50 is used to control the condensed water in the water tank 40 to be discharged from the water tank 40; the water level sensor 60, the water level sensor 60 is arranged in the water tank 40, and is used to detect the water level of the condensed water in the water tank 40, and generate water level data, and send the water level data to the controller; the controller is communicated with the first solenoid valve 30, the second solenoid valve 50 and the water level sensor 60, and the controller is used to control the first solenoid valve 30 and / or the second solenoid valve 50 to operate according to the water level data so that the condensed water accumulated in the water collection structure 20 is discharged to the water tank 40 or the condensed water in the water tank 40 is discharged from the water tank 40 to the external environment.

[0045] Specifically, refer to Figure 2 The fins 110 of the intercooler 100 serve as the main heat dissipation element. When the high-temperature and high-pressure mixed gas flows through the intercooler 100, the water vapor in the mixed gas will be cooled into liquid water (condensed water) on the surface of the fins 110. Under the influence of gravity and airflow, the condensed water will flow from the lower wall inside the intercooler 100 to the outlet end 120 of the intercooler 100. At the same time, a small amount of condensed water will also flow from the side wall and upper wall inside the intercooler 100 to the outlet end 120 of the intercooler 100.

[0046] In order to prevent the condensed water from flowing out from the outlet end 120 of the intercooler 100 , a water retaining structure 10 is provided at the outlet end 120 , which can block the condensed water flowing toward the outlet end 120 of the intercooler 100 .

[0047] It should be noted that, as shown in Reference 3, the water retaining structure 10 can be designed to be inclined, wherein the upper end of the water retaining structure 10 is closer to the fin 110 of the intercooler 100 than the lower end, so that the condensed water blocked by the upper wall and side wall inside the intercooler 100 can better flow to the lower end of the water retaining structure 10 under the action of gravity, thereby improving the collection efficiency of the condensed water.

[0048] refer to Figure 2-Figure 4 The water collecting structure 20 can be a partially recessed water collecting trough, which is arranged at the bottom of the outlet end 120 (i.e., the lower wall surface of the outlet end 120 of the intercooler 100), and is located between the water retaining structure 10 and the fins 110 of the intercooler 100, so as to ensure that the condensed water blocked by the water retaining structure 10 will not flow back to the fins 110 of the intercooler 100, but will be accumulated by the water collecting structure 20. The water collecting structure 20 can also collect the condensed water flowing out of the fins 110 of the intercooler 100, so as to ensure that the condensed water in the intercooler 100 can be fully collected.

[0049] refer to Figure 1 and Figure 6 The water collection structure 20 is connected to the water storage tank 40, and the water storage tank 40 can store the condensed water discharged from the water collection structure 20. The first solenoid valve 30 is arranged between the water storage tank 40 and the water collection structure 20, and is used to control the selective connection between the water collection structure 20 and the water storage tank 40. The first solenoid valve 30 can also control and adjust the pressure in the water storage tank 40 so that the condensed water in the water storage tank 40 can be discharged smoothly; the second solenoid valve 50 is arranged on the side of the water storage tank 40 away from the water collection structure 20, and is used to cooperate with the first solenoid valve 30 to open and control the condensed water in the water storage tank 40 to be discharged from the water storage tank 40.

[0050] refer to Figure 6-Figure 7A water level sensor 60 is also provided inside the water tank 40. The water level sensor 60 is located on one side of the water tank 40 in the axial direction close to the first solenoid valve 30. For example, the volume of the water tank 40 may be 300 ml, and the water level sensor 60 may be provided at three quarters of the volume of the water tank 40, so as to ensure that the water tank 40 can store as much condensed water as possible while retaining part of the cavity portion, so that the air originally stored in the water tank 40 can have enough space to be compressed. When the first solenoid valve 30 controls and adjusts the pressure in the water tank 40, the water in the water tank 40 can be discharged smoothly.

[0051] The controller is communicatively connected with the first solenoid valve 30, the second solenoid valve 50 and the water level sensor 60. The water level sensor 60 can detect the water level of the condensed water stored in the water tank 40, and generate water level data to send to the controller. The controller further controls the first solenoid valve 30 and the second solenoid valve 50 accordingly according to the water level data, so that the condensed water accumulated in the water collection structure 20 can be discharged to the water tank 40, or the water in the water tank 40 can be discharged to the external environment.

[0052] It should be noted that the solenoid valve consists of an electromagnetic coil and a valve body. The movement of the valve body is manipulated by controlling the on and off of the electromagnetic coil, thereby changing the fluid path. When the electromagnetic coil is energized, an electromagnetic force is generated to attract the valve body to move, causing a through hole to open or close, thereby controlling the flow of the fluid.

[0053] As an optional embodiment, refer to Figure 4 , Figure 5 and Figure 8 The retaining structure is composed of an annular water retaining rib, and the outer peripheral surface of the annular water retaining rib is water-tightly connected to the inner peripheral surface of the outlet end 120 of the intercooler 100.

[0054] Specifically, Figure 8 As shown, the water retaining structure 10 at the outlet end 120 can be an annular water retaining rib, and the water retaining structure 10 is arranged at a position close to the outlet end 120 of the intercooler 100, so as to ensure that the condensed water around the inner wall of the intercooler 100 can be blocked by the water retaining structure 10 when flowing to the outlet end 120. The water retaining rib structure can be designed as a trumpet shape (such as Figure 5 As shown), it can fit closely with the shape of the inner wall of the intercooler 100, thereby increasing the blocking and guiding effects on the condensed water, so that the condensed water can be fully blocked. At the same time, the trumpet shape can also reduce the obstruction to the airflow, so that the mixed gas cooled by the intercooler 100 can flow smoothly to the outlet end 120, thereby ensuring the combustion efficiency of the engine cylinder.

[0055] As an optional embodiment, refer to Fig. 9A water outlet 201 is provided at the lowest point of the water collecting structure 20 , and the water outlet 201 is used to discharge the condensed water accumulated in the water collecting structure 20 to the water storage tank 40 .

[0056] Specifically, the lowest point of the water collecting structure 20 is provided with a water outlet 201, which can discharge the condensed water accumulated in the water collecting structure 20 to the water storage tank 40. The specific position or orientation of the water outlet 201 on the water collecting structure 20 can be designed according to the position of the intercooler 100 in the vehicle. The cross section of the water collecting structure 20 can be a V-shaped structure, so that the condensed water can be better discharged into the water storage tank 40. In addition, the width of the water collecting structure 20 can be slightly wider than the water retaining structure 10, so that the condensed water blocked by the water retaining structure 10 can be better collected in the water collecting structure 20.

[0057] As an optional embodiment, refer to Figure 6 The first solenoid valve 30 is provided with a first sub-valve 301 and a second sub-valve 302; the first sub-valve 301 controls the water collection structure 20 to be selectively connected with the water storage tank 40, and the second sub-valve 302 controls the water storage tank 40 to be selectively connected with the atmospheric environment.

[0058] Specifically, the first solenoid valve 30 includes a first sub-valve 301 and a second sub-valve 302. The first sub-valve 301 controls the on-off of the first sub-pipeline 303, and the second sub-valve 302 controls the on-off of the second sub-pipeline 304. The first pipeline 202 is connected to the first sub-pipeline 303, the second sub-pipeline 304 is connected to the atmospheric environment, and the third sub-pipeline 305 is connected to the water storage tank 40.

[0059] It should be noted that the first solenoid valve 30 can be a dual-way single-outlet solenoid valve, which is a solenoid valve with two input paths and one output path. In the embodiment of the present invention, when the first solenoid valve 30 is not energized, the valve core is often on the side of the first sub-valve 301, at which time the first sub-pipeline 303 is connected to the third sub-pipeline 305, the second sub-pipeline 304 is disconnected from the third sub-pipeline 305, and the condensed water flows from the first sub-pipeline 303 through the internal channel of the first sub-valve 301 to the third sub-pipeline 305 to the water storage tank 40; when the first solenoid valve 30 is energized, the valve core will be attracted to the side of the second sub-valve 302, at which time the second sub-pipeline 304 is connected to the third sub-pipeline 305, the first sub-pipeline 303 is disconnected from the third sub-pipeline 305, and the atmosphere flows from the second sub-pipeline 304 through the internal channel of the first sub-valve 301 to the third sub-pipeline 305 to the water storage tank 40.

[0060] It should be noted that the second sub-pipeline 304 can also be connected to a pressurized environment, which can be a gas tank storing high-pressure gas, etc. At this time, the gas pressure in the pressurized environment needs to be greater than the gas pressure in the water tank 40, so that the condensed water in the water tank 40 can be pressed out of the water tank 40 under the action of the pressure difference.

[0061] As an optional embodiment, refer to Figure 6 The second solenoid valve 50 controls the water storage tank 40 to selectively communicate with the external environment.

[0062] The second solenoid valve 50 is used to control the on-off of the second pipeline 501 . The second pipeline 501 is connected to the external environment and is used to discharge the condensed water in the water storage tank 40 to the external environment.

[0063] As an optional embodiment, refer to Figure 6 When the first sub-valve 301 is opened, the water collection structure 20 is connected to the water storage tank 40, and when the first sub-valve 301 is closed, the water collection structure 20 is not connected to the water storage tank 40; when the second sub-valve 302 is opened, the water storage tank 40 is connected to the atmospheric environment, and when the second sub-valve 302 is closed, the water storage tank 40 is not connected to the atmospheric environment; when the second solenoid valve 50 is opened, the water storage tank 40 is connected to the external environment, and when the second solenoid valve 50 is closed, the water storage tank 40 is not connected to the external environment; when the second sub-valve 302 and the second solenoid valve 50 are opened, the first sub-valve 301 is closed; when the first sub-valve 301 is opened, the second sub-valve 302 and the second solenoid valve 50 are closed.

[0064] Specifically, when the first sub-valve 301 is in an open state, the second sub-valve 302 is in a closed state, and the second solenoid valve 50 is also in a closed state. The water tank 40 is now connected to the water collection structure 20, and the condensed water flows from the water collection structure 20 through the first pipe 202, enters the first sub-pipe 303, and then flows through the third sub-pipe 305 to the water tank 40; when the first sub-valve 301 is in a closed state, the second sub-valve 302 is in an open state, and the second solenoid valve 50 is also in an open state. The water tank 40 is now connected to the atmospheric environment, and the condensed water in the water tank 40 can flow from the water tank 40 through the second pipe 501 to the external environment under the action of atmospheric pressure.

[0065] It should be noted that the second solenoid valve 50 may be in a normally closed state and open when powered on.

[0066] It should be noted that the first sub-valve 301 of the first solenoid valve 30 cannot be opened at the same time as the second solenoid valve 50, that is, the condensed water cannot flow directly from the first sub-pipe 303 through the water storage tank 40 and then directly through the second pipe 501 to the external environment, so as to avoid the high-pressure gas flowing through the intercooler 100 from leaking into the external environment, thereby ensuring the stability of the vehicle operation and avoiding environmental pollution.

[0067] refer to Fig.10 , which is a working flow chart of the condensate discharge system provided in an embodiment of the present invention.

[0068] As an optional embodiment, when the EGR system is not operating, that is, the intercooler 100 is not operating, that is, no condensed water is generated, the condensed water discharge system is in a non-working state, the first solenoid valve 30 and the second solenoid valve 50 are both not powered on, the first sub-valve 301 of the first solenoid valve 30 is in an open state, and the second solenoid valve 50 is in a closed state, so as to avoid the high-temperature and high-pressure mixed gas passing through the intercooler 100 from leaking from the condensed water discharge system to the external environment and polluting the external environment.

[0069] As an optional embodiment, when the EGR system is running, that is, the intercooler 100 starts to run, the intercooler 100 will produce condensed water, the condensed water discharge system is in a working state, the first solenoid valve 30 and the second solenoid valve 50 remain de-energized, the first sub-valve 301 of the first solenoid valve 30 is in a long-term open state, and the second solenoid valve 50 is in a closed state. The water vapor in the high-temperature and high-pressure mixed gas passing through the intercooler 100 is cooled into condensed water under the action of the intercooler 100. The condensed water flows toward the water outlet of the intercooler 100 under the action of gravity or airflow impact, so that it can be blocked by the water retaining structure 10 of the condensed water discharge system and collected in the water collecting structure 20. The water in the water collecting structure 20 is discharged to the water storage tank 40 through the first pipe 202. The condensed water is collected by the water storage tank 40, and the water level of the condensed water in the water storage tank 40 is detected by the water level sensor 60. During the time when the water level sensor 60 does not detect that the water level of the condensed water in the water storage tank 40 reaches the preset water level, the second solenoid valve 50 remains closed, and the water storage tank 40 is not connected to the external environment. When the water level sensor 60 detects that the water level of the condensed water in the water storage tank 40 reaches the preset water level, the controller activates the first solenoid valve 30 and the second solenoid valve 50. The second solenoid valve 50 sends the first instruction and the second instruction to power on the first solenoid valve 30 and the second solenoid valve 50. At this time, the first sub-valve 301 in the first solenoid valve 30 is closed, and the second sub-valve 302 is opened. At the same time, the second solenoid valve 50 is opened for a preset time to connect the water storage tank 40 with the atmospheric environment and the external environment, and the condensed water in the water storage tank 40 can be fully discharged into the external environment. After the preset opening time is reached, the controller sends the third instruction and the fourth instruction to the first solenoid valve 30 and the second solenoid valve 50 to power off the first solenoid valve 30 and the second solenoid valve 50. At this time, the first sub-valve 301 in the first solenoid valve 30 is opened, the second sub-valve 302 is closed, and at the same time, the second solenoid valve 50 is closed, so that the water storage tank 40 is not connected with the atmospheric environment and the external environment, and the water storage tank 40 continues to collect the condensed water discharged by the water collection structure 20.

[0070] From the above description, it can be seen that the condensed water discharge system provided by the present invention collects the condensed water at the outlet end of the intercooler 100 by arranging a water retaining structure 10 and a water collecting structure 20 at the outlet end 120 of the intercooler 100, while not affecting the overall external structural dimensions of the intercooler 100, and is easy to arrange the intercooler 100 in the engine compartment. In addition, the condensed water discharge system also utilizes a water storage tank 40 and a solenoid valve to effectively store and discharge the condensed water, thereby preventing the condensed water from flowing into the cylinder of the vehicle engine and causing adverse effects on the combustion of the cylinder, thereby enabling the engine to burn normally at a higher EGR rate, which helps to achieve lower vehicle fuel consumption.

[0071] Based on the same inventive concept, corresponding to the condensate discharge system provided in any of the above embodiments, the present invention also provides a control method for a condensate discharge system.

[0072] refer to Fig.11 , which is a flow chart of a control method for a condensate discharge system provided in an embodiment of the present invention.

[0073] In an embodiment of the present invention, a control method of a condensate discharge system is applied to the condensate discharge system, comprising:

[0074] S1101, obtaining water level data of condensed water in a water storage tank, and determining whether the water level data exceeds a preset water level.

[0075] Specifically, after obtaining the water level data of the condensed water in the water storage tank transmitted by the water level sensor, the control unit determines whether the water level data exceeds a preset water level.

[0076] S1102, in response to the water level data exceeding the preset water level, sends a first instruction to the first solenoid valve, and sends a second instruction to the second solenoid valve, so that the first sub-valve is closed according to the first instruction to control the water collection structure to be disconnected from the water storage tank, and the second sub-valve is opened according to the first instruction to control the water storage tank to be connected to the atmosphere to adjust the pressure in the water storage tank; and the second solenoid valve is opened according to the second instruction to control the water storage tank to be connected to the external environment, so that the condensed water in the water storage tank is discharged from the water storage tank to the external environment.

[0077] Specifically, when the water level data exceeds the preset water level, a first instruction is sent to the first solenoid valve, and a second instruction is sent to the second solenoid valve, wherein the first instruction and the second instruction can be power-on instructions. At this time, the first sub-valve is closed, the second sub-valve is opened, and the second solenoid valve is opened, so that the water storage tank is not connected to the water collection structure, and the water storage tank is connected to the atmospheric environment. Under the action of atmospheric pressure, the condensed water in the water storage tank can be smoothly discharged to the external environment along the second pipeline.

[0078] It should be noted that the first instruction and the second instruction also include controlling the opening time of the second sub-valve and the second solenoid valve. The opening time can be set according to the volume of the water storage tank and the drainage speed. In the control method provided in the embodiment of the present invention, the opening time can be 30s, which can ensure that the water in the water storage tank can be completely discharged to the external environment within the opening time, thereby effectively improving the work efficiency provided by the condensed water discharge.

[0079] As an optional embodiment, after the condensed water in the water tank is discharged from the water tank to the external environment, the method also includes: in response to the water level data not exceeding the preset water level, sending a third instruction to the first solenoid valve, sending a fourth instruction to the second solenoid valve, so that the first sub-valve is opened according to the third instruction to control the water collection structure to be connected to the water tank, the second sub-valve is closed according to the third instruction to control the water tank to be disconnected from the atmospheric environment, and the second solenoid valve is closed according to the fourth instruction to control the water tank to be disconnected from the external environment.

[0080] Specifically, after the condensed water in the water tank is discharged to the external environment, the control system sends a third instruction to the first solenoid valve and a fourth instruction to the fourth solenoid valve. The third instruction and the fourth instruction can be power-off instructions. At this time, the first sub-valve is opened, the second sub-valve is closed, and the second solenoid valve is closed, so that the water tank is connected to the water collecting structure, and the water tank is not connected to the atmospheric environment and the external environment, ensuring that the water discharged from the water collecting structure into the water tank will not be directly discharged into the external environment, so as to avoid the high-pressure gas flowing through the intercooler from leaking into the external environment, thereby ensuring the stability of vehicle operation.

[0081] From the above description, it can be seen that the control method of the condensate discharge system provided by the present invention, through the selective control of the solenoid valve, can enable the condensate in the water storage tank to be fully discharged, thereby improving the discharge efficiency of the condensate at the outlet end of the intercooler, and avoiding the condensate flowing into the cylinder of the vehicle engine to cause poor combustion or other adverse effects on the cylinder, thereby improving the operating efficiency of the vehicle engine and helping to reduce the fuel consumption of the entire vehicle.
