Description

Technical Field

[0001] This application relates to the technical field of automotive power systems, and particularly to an automotive intercooler. Background Art

[0002] Common intake methods for automobiles are natural aspiration and turbocharging. Generally, automobiles with turbocharging as the intake method are equipped with an intercooler. One end of the intercooler is connected to the automotive turbocharger, and the other end is connected to the engine cylinder. After the air is compressed by the turbocharger, the air temperature will rise. If the turbocharger is directly connected to the engine, the high-temperature air will cause engine knocking and other phenomena. Therefore, the air compressed by the turbocharger needs to be first passed through the intercooler for cooling and then passed into the engine cylinder.

[0003] In the related art of automotive intercoolers, when the vehicle is in high-temperature weather or under aggressive driving conditions, it may cause the temperature of the air entering the engine to be too high, thereby damaging the engine; when the vehicle is in a relatively low-temperature environment, it may cause the temperature of the air entering the engine to be too low, resulting in incomplete combustion and thus generating carbon deposits. Summary of the Invention

[0004] The embodiments of this application provide an automotive intercooler, which can improve the technical problem of the air temperature being too high or too low after being processed by the intercooler in the related art.

[0005] The embodiments of this application provide an automotive intercooler, including:

[0006] An intercooler main body, including a water-cooling part with a water-cooling channel, an air-cooling part with an air-cooling channel, and a conversion part; the water-cooling part is connected to the air-cooling part; a part of the conversion part is arranged at one end of the water-cooling part and the air-cooling part, and the other part of the conversion part is arranged at the other end of the water-cooling part and the air-cooling part; the conversion part is respectively communicated with the air-cooling channel and the water-cooling channel;

[0007] A first connecting piece, arranged on one side of the intercooler main body, the first connecting piece has a first space and a first connecting channel, the first connecting channel is communicated with the conversion part, and the first connecting channel is also communicated with the automotive turbocharger; and

[0008] A second connecting piece, arranged on the other side of the intercooler main body, the second connecting piece has a second space and a second connecting channel, the second connecting channel is communicated with the conversion part, and the second connecting channel is also communicated with the automotive engine;

[0009] Wherein, the conversion part is used to enable air to pass through the water-cooling part and the air-cooling part in sequence when the air temperature in the first connection channel is higher than the preset temperature; and to enable air to only pass through the air-cooling part when the air temperature in the first connection channel is lower than the preset temperature.

[0010] In the technical solution described above in the embodiments of the present application, at least the following technical effects are achieved:

[0011] The automotive intercooler provided in the embodiments of the present application is configured as an automotive intercooler including a water-cooling part and an air-cooling part, and a conversion part is provided to adjust the flow direction of the gas in the automotive intercooler; when the temperature of the compressed air entering the automotive intercooler is lower than the preset temperature, the conversion part opens the connection relationship between the air-cooling channel and the first connection channel, and at the same time closes the connection relationship between the first connection channel and the water-cooling channel, and the conversion part closes the connection relationship between the air-cooling part and the water-cooling part, so that the compressed air entering the automotive intercooler only passes through the air-cooling part; when the temperature of the compressed air entering the automotive intercooler is higher than the preset temperature, the conversion part opens the connection relationship between the first connection channel and the water-cooling channel, and at the same time the conversion part closes the connection relationship between the air-cooling channel and the first connection channel, and the conversion part opens the connection relationship between the air-cooling part and the water-cooling part; compared with directly using an air-cooled intercooler or a water-cooled intercooler, the above solution can make the compressed gas only pass through the air-cooling part when the temperature is not high, while shortening the cooling stroke in the automotive intercooler, so as to reduce the cooling range of the compressed air, and further prevent the temperature of the compressed air entering the engine from being too low, thereby preventing the carbon deposition of the automotive engine from increasing. When the temperature is too high, the compressed air passes through the water-cooling part and the air-cooling part in sequence, while lengthening the cooling stroke in the automotive intercooler, so as to increase the cooling range of the compressed air, and further prevent the temperature of the compressed air entering the engine from being too high, thereby preventing the automotive engine from knocking. At the same time, in the prior art, the flow direction of the air in the intercooler is fixed, and during the cooling process, the temperature at one end of the air inlet of the intercooler is higher than the temperature at the air outlet end of the intercooler. If it is in this state for a long time, the service life of the intercooler will be shortened. In the solution of the present application, the flow direction of the compressed air when the temperature of the compressed air is too high in the air-cooling part is opposite to the flow direction of the compressed air when the temperature of the compressed air is too high, which can extend the service life of the automotive intercooler.

[0065] An automotive intercooler is a device with one end connected to an automotive turbocharger and the other end connected to the cylinder of an engine; its main function is to cool the gas processed by the turbocharger.

[0066] In the related art, for an automotive intercooler, when the vehicle is in high-temperature weather or under violent driving conditions, it may cause the temperature of the air entering the engine to be too high, thereby damaging the engine; when the vehicle is in a relatively low-temperature condition, it may cause the temperature of the air entering the engine to be too low, resulting in incomplete combustion and then carbon deposition.

[0067] Based on this, in order to improve the problem that the temperature of the air processed by the intercooler in the related art is too high or too low, the embodiments of this application provide the following solutions.

[0068] Please refer to Figure 1 and Figure 2 , the embodiments of this application provide an automotive intercooler 100, which includes an intercooler main body 10, a first connector 20, and a second connector 30. Among them:

[0069] The intercooler main body 10 includes a water-cooling part 11 having a water-cooling channel 110, an air-cooling part 12 having an air-cooling channel 120, and a conversion part 13; the water-cooling part 11 is connected to the air-cooling part 12; a part of the conversion part 13 is disposed at one end of the water-cooling part 11 and the air-cooling part 12, and another part of the conversion part 13 is disposed at the other end of the water-cooling part 11 and the air-cooling part 12; the conversion part 13 is respectively communicated with the air-cooling channel 120 and the water-cooling channel 110.

[0070] The first connector 20 is disposed on one side of the intercooler main body 10. The first connector 20 has a first space 200 and a first connection channel 201. The first connection channel 201 is communicated with the conversion part 13, and the first connection channel 201 is also communicated with the air outlet of the automotive turbocharger.

[0071] The second connecting member 30 is disposed on the other side of the intercooler main body 10. The second connecting member 30 has a second space 300 and a second connecting passage 301. The second connecting passage 301 communicates with the conversion portion 13 and also communicates with the air inlet of the vehicle engine.

[0072] Wherein, the conversion portion 13 is configured to enable the air to sequentially pass through the water-cooling portion 11 and the air-cooling portion 12 when the air temperature in the first connecting passage 201 is higher than a preset temperature; and to enable the air to only pass through the air-cooling portion 12 when the air temperature in the first connecting passage 201 is lower than the preset temperature.

[0073] It can be understood that the intercooler main body 10 is a main body for cooling compressed air; for example, the intercooler main body 10 may be a component composed of a water-cooling portion 11, an air-cooling portion 12, and heat sinks. The water-cooling portion 11 is a component for water-cooling the compressed air; for example, the water-cooling portion 11 may be a metal pipe passing through the vehicle radiator. The air-cooling portion 12 is a component for air-cooling the compressed air; for example, the air-cooling portion 12 may be a plurality of connected parallel metal pipes. The conversion portion 13 is a component for changing the flow direction of the compressed air in the intercooler main body 10; for example, the conversion portion 13 may be a component composed of a first integrated pipe 131, a second integrated pipe 132, a first conversion member 133, and a second conversion member 134; or for another example, the conversion portion 13 may also be a component composed of a plurality of electric motors, a plurality of switching valves, a temperature sensor, and a control unit. The temperature sensor detects the temperature of the compressed air and sends it to the control unit for processing, and then the control unit controls the plurality of switching valves through the plurality of electric motors to change the flow direction of the compressed air in the intercooler main body 10. The first connecting member 20 is a component for connecting the turbocharger; for example, the first connecting member 20 may be a metal member having an installation space and a connecting pipe. The second connecting member 30 is a component for connecting the engine; for example, the second connecting member 30 may be a metal member having an installation space and a connecting pipe.

[0074] As can be seen from the above, the automotive intercooler 100 provided by the embodiments of the present application is configured such that the automotive intercooler 100 includes a water-cooling part 11 and an air-cooling part 12, and a conversion part 13 is provided to adjust the flow direction of the gas in the automotive intercooler 100; when the temperature of the compressed air entering the automotive intercooler 100 is less than the preset temperature, the conversion part 13 opens the communication relationship between the air-cooling channel 120 and the first connection channel 201, and at the same time closes the communication relationship between the first connection channel 201 and the water-cooling channel 110, and the conversion part 13 closes the communication relationship between the air-cooling part 12 and the water-cooling part 11, so that the compressed air entering the automotive intercooler 100 only passes through the air-cooling part 12; when the temperature of the compressed air entering the automotive intercooler 100 is higher than the preset temperature, the conversion part 13 opens the communication relationship between the first connection channel 201 and the water-cooling channel 110, and at the same time the conversion part 13 closes the communication relationship between the air-cooling channel 120 and the first connection channel 201, and the conversion part 13 opens the communication relationship between the air-cooling part 12 and the water-cooling part 11; compared with directly using an air-cooled intercooler or a water-cooled intercooler, the above solution can make the compressed gas only pass through the air-cooling part 12 when the temperature is not high, and at the same time shorten the cooling stroke in the automotive intercooler 100 thereof, so as to reduce the cooling amplitude of the compressed air, and further prevent the temperature of the compressed air entering the engine from being too low, thereby preventing an increase in carbon deposition in the automotive engine. When the temperature is too high, the compressed air passes through the water-cooling part 11 and the air-cooling part 12 in sequence, and at the same time lengthens the cooling stroke in the automotive intercooler 100 thereof, so as to increase the cooling amplitude of the compressed air, and further prevent the temperature of the compressed air entering the engine from being too high, thereby preventing engine knocking in the automotive engine. At the same time, the flow direction of the air in the intercooler in the prior art is fixed, and the temperature at one end of the air inlet of the intercooler is higher than the temperature at the air outlet end during the cooling process. Being in such a state for a long time will shorten the service life of the intercooler. In the solution of the present application, the flow direction of the compressed air in the air-cooling part 12 when the temperature of the compressed air is too high is opposite to the flow direction of the compressed air when the temperature of the compressed air is too high, so as to be able to extend the service life of the automotive intercooler 100.

[0075] In some embodiments, please also refer to Figure 1 and Figure 2 , the water-cooling part 11 includes a water-cooling pipe 111 detachably arranged in the automotive radiator, and the flow direction of the gas in the water-cooling pipe 111 is the same as the flow direction of the coolant in the automotive radiator.

[0076] With such a setting, by arranging the water-cooling pipe 111 detachably in the radiator, the complexity of the automotive cooling system can be reduced, and thus the manufacturing cost can be reduced. And the flow direction of the gas in the water-cooling pipe 111 is the same as the flow direction of the coolant in the automotive radiator, so as to be able to reduce the influence of the water-cooling pipe 111 on the temperature of the coolant at the outlet of the radiator.

[0077] Optionally, in some embodiments, refer to Figures 1 to 3 , the conversion unit 13 includes a first integrated pipe 131, a second integrated pipe 132, a first conversion member 133, and a second conversion member 134. Among them:

[0078] The first integrated pipe 131 is disposed at one end of the air-cooling part 12, and the first integrated pipe 131 communicates with the air-cooling channel 120.

[0079] The second integrated pipe 132 is disposed at the other end of the air-cooling part 12, and the second integrated pipe 132 communicates with the air-cooling channel 120.

[0080] The first conversion member 133 is located in the first space 200. The first conversion member 133 has a first intake main pipe 1331, a first exhaust main pipe 1332, and a first exhaust branch pipe 1333. The first intake main pipe 1331 communicates with the first connection channel 201, the first exhaust main pipe 1332 communicates with the first integrated pipe 131, and the first exhaust branch pipe 1333 communicates with the water-cooling channel 110.

[0081] The second conversion member 134 is located in the second space 300. The second conversion member 134 has a second intake main pipe 1341, a second intake branch pipe 1342, and a second exhaust main pipe 1343. The second intake main pipe 1341 communicates with the second integrated pipe 132, the second intake branch pipe 1342 communicates with the water-cooling channel 110, and the second exhaust main pipe 1343 communicates with the second connection channel 301.

[0082] Among them, when the air temperature in the first space 200 is higher than the preset temperature, the first conversion member 133 is used to close the first exhaust main pipe 1332 and open the first exhaust branch pipe 1333, so as to drive the second conversion member 134 to open the second intake branch pipe 1342 and close the second exhaust main pipe 1343.

[0083] When the air temperature in the first space 200 is lower than the preset temperature, the first conversion member 133 is further used to open the first exhaust main pipe 1332 and close the first exhaust branch pipe 1333, so as to drive the second conversion member 134 to close the second intake branch pipe 1342 and open the second exhaust main pipe 1343.

[0084] It can be understood that the first integrated pipe 131 is one of the components for connecting the air-cooling channels 120 in the air-cooling part 12; for example, the first integrated pipe 131 can be a metal pipe with one inlet and multiple outlets. The second integrated pipe 132 is one of the components for connecting the air-cooling channels 120 in the air-cooling part 12; for example, the second integrated pipe 132 can be a metal pipe with one inlet and multiple outlets. The first conversion part 133 is a component for connecting the first integrated pipe 131, the first connection channel 201 and the water-cooling pipe 111; for example, the first conversion part 133 can be a three-way metal pipe with a first switch part 1335 and a second switch part 1336. The second conversion part 134 is a component for connecting the second integrated pipe 132, the second connection channel 301 and the water-cooling pipe 111; for example, the second conversion part 134 can be a three-way metal pipe with a third switch part 1345.

[0085] With such a setting, by providing the first integrated pipe 131 and the second integrated pipe 132 to connect the air-cooling channels 120 in the air-cooling part 12, it is convenient for the first conversion part 133 and the second conversion part 134 to control the air-cooling part 12, and then to control the connection relationship between the air-cooling part 12 and the water-cooling part 11 in the automotive intercooler 100, and further to simplify the structures of the first conversion part 133 and the second conversion part 134. If the first conversion part 133 and the second conversion part 134 are set as electric control valves, since the working environment of the first conversion part 133 and the second conversion part 134 belongs to a high-temperature environment, it will cause the normal operation of the electric control valves. In this application, the first conversion part 133 and the second conversion part 134 are of a pure mechanical structure, which can avoid the above problems.

[0086] Optionally, please refer to Figures 1 to 3 , the first conversion part 133 includes a first conversion main body 1334, a first switch part 1335 and a second switch part 1336. Among them:

[0087] The first conversion main body 1334 has a first air intake main pipe 1331, a first air outlet main pipe 1332 and a first air outlet branch pipe 1333.

[0088] The first switch part 1335 is partially arranged in the first air intake main pipe 1331, and the other part is movably arranged in the first air outlet main pipe 1332. The first switch part 1335 is used to open or close the first air outlet main pipe 1332.

The second switch 1336 is a component for opening or closing the first air outlet branch pipe 1333; for example, the second switch 1336 can be a component composed of a first elastic element 13361, a connecting plate 13362, a second connecting rod 13363, and a second closing piston 13364; furthermore, for example, the second switch 1336 can also be a component composed of a motor and a switching valve.

[0091] With such a setting, the first main air outlet pipe 1332 and the first air outlet branch pipe 1333 are respectively controlled by using the first switch 1335 and the second switch 1336. Compared with the solution of directly controlling the first main air outlet pipe 1332 and the first air outlet branch pipe 1333 through one switch, the above solution can avoid the confusion in the control of the first main air outlet pipe 1332 and the first air outlet branch pipe 1333.

And the first closing piston 13356 is movably arranged in the first main air outlet pipe 1332.

[0095] The push medium 13353 is arranged in the first push hole 13350.

[0096] Among them, the driving medium 13353 is used to expand or contract within the first driving cylinder 13351 under the influence of temperature, and then drive the first closing piston 13356 to move within the first main air outlet pipe 1332 through the first driving piston 13354 and the first connecting rod 13355, thereby opening or closing the first main air outlet pipe 1332.

[0097] It can be understood that the first driving cylinder 13351 is a component for placing the driving medium 13353; for example, the first driving cylinder 13351 can be a metal cylinder body or a metal box body, etc. The first driving member 13352 is a component for opening or closing the first main air outlet pipe 1332; for example, the first driving member 13352 can be a component composed of the first driving piston 13354, the first connecting rod 13355, and the first closing piston 13356. Another example is that the first driving member 13352 can also be a member in which two pistons are connected. The driving medium 13353 is a component for sensing temperature and controlling the first driving member 13352 according to the temperature. For example, the driving medium 13353 can be expanded graphite or carbon fiber reinforced epoxy resin (CFRP), etc.

[0098] With such a setting, the first switching member 1335 composed of the first driving cylinder 13351, the first driving member 13352, and the driving medium 13353; compared with the switching member composed of a motor and a valve, the above solution can control the opening of the first main air outlet pipe 1332 according to the temperature of the compressed air, and can simplify the structure and reduce costs.

[0099] In some embodiments, please refer to Figures 1 to 3 , the first air outlet branch pipe 1333 includes a first branch pipe 13331 and a second branch pipe 13332. The diameter of the first branch pipe 13331 is larger than that of the second branch pipe 13332. The first branch pipe 13331 is communicated with the second branch pipe 13332, and the second branch pipe 13332 is communicated with the first main air inlet pipe 1331. The second switching member 1336 includes a first elastic element 13361, a connecting plate 13362, a second connecting rod 13363, and a second closing piston 13364. Among them:

[0100] One end of the first elastic element 13361 is connected to the side wall of the second branch pipe 13332 facing the first branch pipe 13331.

[0101] The connecting plate 13362 is movably arranged in the first branch pipe 13331, and the side wall of the connecting plate 13362 facing the second branch pipe 13332 is connected to the other end of the first elastic element 13361.

[0102] The second connecting rod 13363 is located in the first branch pipe 13331, and one end of the second connecting rod 13363 is connected to the side wall of the connecting plate 13362 facing the second branch pipe 13332.

[0104] Wherein, the first elastic element 13361 is configured to drive the second closing piston 13364 to move towards the second branch pipe 13332 through the connecting plate 13362 and the second connecting rod 13363 when the first switching element 1335 opens the first main air outlet pipe 1332, thereby closing the first branch air outlet pipe 1333; the first elastic element 13361 is further configured to drive the second closing piston 13364 to move away from the second branch pipe 13332 through the connecting plate 13362 and the second connecting rod 13363 when the first switching element 1335 closes the first main air outlet pipe 1332, thereby opening the first branch air outlet pipe 1333.

[0105] It can be understood that the first elastic element 13361 is a device for providing a force for the second closing piston 13364 to close the first branch air outlet pipe 1333; for example, the first elastic element 13361 can be a spring or a rubber cord, etc. The connecting plate 13362 is a member for connecting the spring; for example, the connecting plate 13362 can be a metal plate. The second closing piston 13364 is a member for opening or closing the first branch air outlet pipe 1333; and the diameter of the second closing piston 13364 is between the channel diameter of the first branch pipe 13331 and the channel diameter of the second branch pipe 13332.

[0106] With such a setting, when the first switching element 1335 opens the first main air outlet pipe 1332, under the action of the restoring force of the first elastic element 13361, the second closing piston 13364 is driven to move towards the second branch pipe 13332 through the connecting plate 13362 and the second connecting rod 13363, thereby closing the first branch air outlet pipe 1333; when the first switching element 1335 closes the first main air outlet pipe 1332, the pressure in the second branch pipe 13332 gradually increases, thereby pushing the second closing piston 13364 to move away from the second branch pipe 13332, thereby opening the first branch air outlet pipe 1333. The second switching element 1336 of the above solution can ensure that the gas flow direction in the intercooler is single, so as to avoid the compressed air with two flow directions in the air-cooled channel 120 of the intercooler.

[0107] Optionally, in some embodiments, please refer to Figures 1 to 4 , the second conversion member 134 includes a second conversion main body 1344 and a third switching element 1345. Wherein:

[0109] The third switch member 1345 is movably arranged in the water cooling channel 110, and a sealing treatment is performed between the third switch member 1345 and the inner wall of the water cooling channel 110.

[0110] Wherein, the third switch member 1345 is used to open or close the connection between the water cooling channel 110 and the second integrated pipe 132, and the third switch member 1345 is also used to open or close the connection between the second integrated pipe 132 and the second connection channel 301.

[0111] It can be understood that the second conversion body 1344 is a component for connecting the second integrated pipe 132, the second connection channel 301, and the water cooling pipe 111; for example, the second conversion body 1344 can be a three-way metal pipe or a metal block with three interconnected channels, etc. The third switch member 1345 is a component for controlling the connection between the water cooling channel 110 and the second integrated pipe 132 and the connection between the second integrated pipe 132 and the second connection channel 301; for example, the third switch member 1345 can be a component composed of a second elastic element 13451 and a third push piston 13452.

[0112] With such a setting, by setting the third switch member 1345 to control the connection between the water cooling channel 110 and the second integrated pipe 132 and the connection between the second integrated pipe 132 and the second connection channel 301; the switch states of two pipes can be controlled by one switch, thereby simplifying the structure and saving costs, and at the same time ensuring that when one pipe is open, the other pipe is in a closed state.

[0113] Optionally, please refer to Figures 1 to 4 , the third switch member 1345 includes a second elastic element 13451 and a third push piston 13452. Among them:

[0116] It can be understood that the second elastic element 13451 is a component for providing a restoring force; for example, the second elastic element 13451 can be a spring or an elastic cord, etc.

[0117] With such a setting, the third switching member 1345 is formed by setting the second elastic element 13451 and the third pushing piston 13452, so that when the compressed air only passes through the air-cooling part 12, the third pushing piston 13452 closes the water-cooling channel 110 under the action of the restoring force of the second elastic element 13451 and opens the second connection channel 301; when the compressed air passes through the water-cooling part 11 and the air-cooling part 12 in sequence, the compressed air pushes the third pushing piston 13452 to open the water-cooling channel 110 and close the second connection channel 301. The above solution can control the water-cooling channel 110 and the second connection channel 301 accordingly according to and utilizing the flow direction of the compressed air to ensure the direction of the compressed air flowing out without external kinetic energy provided.
