Description

Technical Field

[0001] The present application relates to the technical field of automobile power systems, and in particular to an automobile intercooler. Background Art

[0002] There are two common air intake methods for automobiles: naturally aspirated and turbocharged. Automobiles that use turbocharging as the air intake method generally have an intercooler. One end of the intercooler is connected to the automobile turbocharger, and the other end is connected to the engine cylinder. The air is compressed by the turbocharger, which will increase the air temperature. If the turbocharger is directly connected to the engine, the high-temperature air will cause engine detonation and other phenomena. Therefore, the air compressed by the turbocharger needs to be passed through the intercooler first to cool it down before being passed into the engine cylinder.

[0003] The car intercooler in the related technology may cause the temperature of the air entering the engine to be too high and damage the engine when the car is in hot weather or violent driving; when the car is in a lower temperature, the temperature of the air entering the engine may be too low, resulting in incomplete combustion and carbon deposits. Summary of the invention

[0004] The embodiment of the present application provides an automobile intercooler, which can improve the technical problem in the related art that the temperature of the air treated by the intercooler is too high or too low.

[0005] The embodiment of the present application provides an automobile intercooler, comprising: The intercooler body comprises a water cooling part having a water cooling channel, an air cooling part having 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 another 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 connected to the air cooling channel and the water cooling channel; a first connecting member, disposed at one side of the intercooler body, the first connecting member having a first space and a first connecting channel, the first connecting channel being connected to the conversion portion, and the first connecting channel being connected to a turbocharger of an automobile; and A second connecting member is disposed on the other side of the intercooler body, the second connecting member has a second space and a second connecting channel, the second connecting channel is connected to the conversion part, and the second connecting channel is also connected to the automobile engine; The conversion part is used to enable the air to pass through the water cooling part and the air cooling part successively when the air temperature in the first connecting channel is higher than a preset temperature; and to enable the air to pass only through the air cooling part when the air temperature in the first connecting channel is lower than a preset temperature.

[0006] The above technical solutions in the embodiments of the present application have at least the following technical effects: The automobile intercooler provided in the embodiment of the present application is configured as an automobile 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 automobile intercooler; when the temperature of the compressed air entering the automobile intercooler is lower than the preset temperature, the conversion part opens the connection between the air cooling channel and the first connecting channel, and simultaneously closes the connection between the first connecting channel and the water cooling channel, and the conversion part closes the connection between the air cooling part and the water cooling part, so that the compressed air entering the automobile intercooler only passes through the air cooling part; when the compressed air entering the automobile intercooler is When the temperature of the air is higher than the preset temperature, the conversion part opens the connection relationship between the first connecting channel and the water cooling channel, and the conversion part closes the connection relationship between the air cooling channel and the first connecting channel, and the conversion part opens the connection relationship between the air cooling part and the water cooling part; compared with directly passing through the air-cooled intercooler or the water-cooled intercooler, the above scheme can allow the compressed gas to pass only through the air cooling part when the temperature is not high, and shorten the cooling stroke in the automobile intercooler to reduce the cooling amplitude of the compressed air, thereby preventing the temperature of the compressed air entering the engine from being too low, thereby preventing the increase of carbon deposition in the automobile engine. When the temperature is too high, the compressed air passes through the water cooling part and the air cooling part successively, and lengthens the cooling stroke in the automobile intercooler to increase the cooling amplitude of the compressed air, thereby preventing the temperature of the compressed air entering the engine from being too high, thereby preventing the automobile engine from knocking. At the same time, the flow direction of the air in the intercooler in the prior art is fixed, which will cause the temperature of one end of the intercooler air inlet to be higher than that of the intercooler air outlet during the cooling process. 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 in the air cooling part 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, thereby increasing the service life of the automobile intercooler.

[0026] The car intercooler is a device that is connected to the car turbocharger at one end and to the cylinder of the engine at the other end; its main function is to cool the gas after being processed by the turbocharger.

[0027] The car intercooler in the related technology may cause the temperature of the air entering the engine to be too high and damage the engine when the car is in hot weather or violent driving; when the car is in a lower temperature, the temperature of the air entering the engine may be too low, resulting in incomplete combustion and carbon deposits.

[0028] Based on this, in order to improve the problem of the air temperature being too high or too low after being treated by the intercooler in the related art, the embodiment of the present application provides the following solution.

[0029] Please also read Figure 1 and Figure 2The embodiment of the present application provides an automobile intercooler 100, which includes an intercooler body 10, a first connecting member 20 and a second connecting member 30. Among them: The intercooler 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 arranged at one end of the water-cooling part 11 and the air-cooling part 12, and another part of the conversion part 13 is arranged at the other end of the water-cooling part 11 and the air-cooling part 12; the conversion part 13 is respectively connected to the air-cooling channel 120 and the water-cooling channel 110.

[0030] The first connecting member 20 is disposed on one side of the intercooler body 10 , and has a first space 200 and a first connecting channel 201 . The first connecting channel 201 is connected to the conversion portion 13 , and the first connecting channel 201 is also connected to the air outlet of the automotive turbocharger.

[0031] The second connecting member 30 is disposed at the other side of the intercooler body 10 , and has a second space 300 and a second connecting channel 301 , wherein the second connecting channel 301 is connected to the conversion portion 13 , and the second connecting channel 301 is also connected to the air intake of the automobile engine.

[0032] Among them, the conversion part 13 is used to allow the air to pass through the water cooling part 11 and the air cooling part 12 successively when the air temperature in the first connecting channel 201 is higher than the preset temperature; and is used to allow the air to only pass through the air cooling part 12 when the air temperature in the first connecting channel 201 is lower than the preset temperature.

[0033] It can be understood that the intercooler body 10 is a body for cooling the compressed air; for example, the intercooler body 10 can be a component composed of a water cooling part 11, an air cooling part 12 and a heat sink. The water cooling part 11 is a component for water cooling the compressed air; for example, the water cooling part 11 can be a metal pipe passing through a car radiator. The air cooling part 12 is a component for air cooling the compressed air; for example, the air cooling part 12 can be a plurality of connected parallel metal pipes. The conversion part 13 is a component for changing the flow direction of the compressed air in the intercooler body 10; for example, the conversion part 13 can be a component composed of a first integrated pipe 131, a second integrated pipe 132, a first conversion part 133 and a second conversion part 134; for another example, the conversion part 13 can also be a component composed of a plurality of motors, a plurality of switch 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, so that the control unit controls the plurality of switch valves through the plurality of motors to change the flow direction of the compressed air in the intercooler body 10. The first connector 20 is a component for connecting the turbocharger; for example, the first connector 20 can be a metal component with an installation space and a connecting pipe. The second connector 30 is a component for connecting the engine; for example, the second connector 30 can be a metal component with an installation space and a connecting pipe.

[0034] As can be seen from the above, the automotive intercooler 100 provided in the embodiment of the present application is configured as an automotive intercooler 100 including 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 lower than the preset temperature, the conversion part 13 opens the connection between the air cooling channel 120 and the first connecting channel 201, and closes the connection between the first connecting channel 201 and the water cooling channel 110, and the conversion part 13 closes the connection 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 entering When the temperature of the compressed air entering the automobile intercooler 100 is higher than the preset temperature, the conversion part 13 opens the connection relationship between the first connecting channel 201 and the water cooling channel 110, and the conversion part 13 closes the connection relationship between the air cooling channel 120 and the first connecting channel 201, and the conversion part 13 opens the connection relationship between the air cooling part 12 and the water cooling part 11; compared with directly passing through the air-cooled intercooler or the water-cooled intercooler, the above scheme can be that when the temperature is not high, the compressed gas only passes through the air cooling part 12, and at the same time shortens its cooling stroke in the automobile intercooler 100 to reduce the cooling range of the compressed air, thereby preventing the temperature of the compressed air entering the engine from being too low, thereby preventing the increase of carbon deposition in the automobile engine. When the temperature is too high, the compressed air passes through the water cooling part 11 and the air cooling part 12 successively, and at the same time lengthens its cooling stroke in the automobile intercooler 100 to increase the cooling range of the compressed air, thereby preventing the temperature of the compressed air entering the engine from being too high, thereby preventing the automobile engine from knocking. At the same time, the flow direction of the air in the intercooler in the prior art is fixed, which will cause the temperature of one end of the intercooler air inlet to be higher than that of the intercooler air outlet during the cooling process. 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 of the air cooling part 12 when the compressed air temperature is too high is opposite to the flow direction of the compressed air when the compressed air temperature is too high, thereby increasing the service life of the automobile intercooler 100.

[0035] In some embodiments, please refer to Figure 1 and Figure 2 The water cooling part 11 includes a water cooling pipe 111 which is detachably arranged in the automobile radiator, and the flow direction of the gas in the water cooling pipe 111 is consistent with the flow direction of the coolant in the automobile radiator.

[0036] In this way, the water cooling pipe 111 is detachably arranged in the radiator, so as to reduce the complexity of the automobile cooling system and thus reduce the manufacturing cost. In addition, the flow direction of the gas in the water cooling pipe 111 is consistent with the flow direction of the coolant in the automobile radiator, so as to reduce the influence of the water cooling pipe 111 on the coolant temperature at the radiator outlet.

[0037] Optionally, in some embodiments, see Figures 1 to 3 The conversion part 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: The first integrated pipe 131 is disposed at one end of the air cooling portion 12 , and the first integrated pipe 131 is communicated with the air cooling channel 120 .

[0038] The second integrated pipe 132 is disposed at the other end of the air-cooling portion 12 , and the second integrated pipe 132 is communicated with the air-cooling channel 120 .

[0039] The first conversion component 133 is located in the first space 200, and has a first air intake main pipe 1331, a first air outlet main pipe 1332 and a first air outlet branch pipe 1333. The first air intake main pipe 1331 is connected to the first connecting channel 201, the first air outlet main pipe 1332 is connected to the first integrated pipe 131, and the first air outlet branch pipe 1333 is connected to the water cooling channel 110.

[0040] The second conversion component 134 is located in the second space 300, and the second conversion component 134 has a second air intake main pipe 1341, a second air intake branch pipe 1342 and a second air outlet main pipe 1343. The second air intake main pipe 1341 is connected to the second integrated pipe 132, the second air intake branch pipe 1342 is connected to the water cooling channel 110, and the second air outlet main pipe 1343 is connected to the second connecting channel 301.

[0041] Among them, the first conversion component 133 is used to close the first air outlet main pipe 1332 and open the first air outlet branch pipe 1333 when the air temperature in the first space 200 is higher than the preset temperature, so as to drive the second conversion component 134 to open the second air inlet branch pipe 1342 and close the second air outlet main pipe 1343.

[0042] The first conversion member 133 is also used to open the first air outlet main pipe 1332 and close the first air outlet branch pipe 1333 when the air temperature in the first space 200 is lower than the preset temperature, so as to drive the second conversion member 134 to close the second air inlet branch pipe 1342 and open the second air outlet main pipe 1343.

[0043] It can be understood that the first integrated pipe 131 is one of the components used to connect 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 used to connect 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 member 133 is a component used to connect the first integrated pipe 131, the first connecting channel 201 and the water-cooling pipe 111; for example, the first conversion member 133 can be a three-way metal pipe with a first switch member 1335 and a second switch member 1336. The second conversion member 134 is a component used to connect the second integrated pipe 132, the second connecting channel 301 and the water-cooling pipe 111; for example, the second conversion member 134 can be a three-way metal pipe with a third switch member 1345.

[0044] In this way, the air-cooling channel 120 in the air-cooling part 12 is connected by setting the first integrated pipe 131 and the second integrated pipe 132, so as to facilitate the first conversion member 133 and the second conversion member 134 to control the air-cooling part 12, and then control the connection relationship between the air-cooling part 12 and the water-cooling part 11 in the automobile intercooler 100, thereby simplifying the structure of the first conversion member 133 and the second conversion member 134. If the first conversion member 133 and the second conversion member 134 are set as electric control valves, because the working environment of the first conversion member 133 and the second conversion member 134 is a high-temperature environment, it will lead to the normal operation of the electric control valve. In this application, the first conversion member 133 and the second conversion member 134 are purely mechanical structures, which will avoid the above problems.

[0045] Optionally, see Figures 1 to 3 The first conversion member 133 includes a first conversion body 1334, a first switch member 1335 and a second switch member 1336. The first conversion body 1334 has a first air inlet main pipe 1331 , a first air outlet main pipe 1332 , and a first air outlet branch pipe 1333 .

[0046] A portion of the first switch element 1335 is disposed in the first air inlet main pipe 1331 , and another portion is movably disposed in the first air outlet main pipe 1332 . The first switch element 1335 is used to open or close the first air outlet main pipe 1332 .

[0047] The second switch element 1336 is movably disposed in the first air outlet branch pipe 1333 , and the second switch element 1336 is used to open or close the first air outlet branch pipe 1333 .

[0048] It can be understood that the first conversion body 1334 is a component for connecting the first integrated pipe 131, the first connecting channel 201 and the water cooling pipe 111; for example, the first conversion body 1334 can be a three-way metal pipe or a metal block with three mutually connected channels. The first switch member 1335 is a component for opening or closing the first outlet main pipe 1332; for example, the first switch member 1335 can be a component composed of a first push cylinder 13351, a first push member 13352 and a push medium 13353; for another example, the first switch member 1335 can also be a component composed of a motor and a switch valve. The second switch member 1336 is a component for opening or closing the first outlet branch pipe 1333; for example, the second switch member 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; for another example, the second switch member 1336 can also be a component composed of a motor and a switch valve.

[0049] In this configuration, the first main gas outlet pipe 1332 and the first branch gas outlet pipe 1333 are respectively controlled by using the first switch 1335 and the second switch 1336. Compared with a solution in which the first main gas outlet pipe 1332 and the first branch gas outlet pipe 1333 are directly controlled by one switch, the above solution can avoid confusion in controlling the first main gas outlet pipe 1332 and the first branch gas outlet pipe 1333.

[0050] For example, see Figures 1 to 3 The first switch member 1335 includes a first push cylinder 13351, a first push member 13352 and a push medium 13353. Wherein: The first pushing cylinder 13351 is disposed in the first air inlet main pipe 1331 , and the opening of the first pushing cylinder 13351 faces the first air outlet main pipe 1332 ; the first pushing cylinder 13351 has a first pushing hole 13350 .

[0051] The first pushing member 13352 includes a first pushing piston 13354, a first connecting rod 13355 and a first closing piston 13356. The first pushing piston 13354 is movably arranged in the first pushing hole 13350. One end of the first connecting rod 13355 is connected to the side of the first pushing piston 13354 toward the opening direction of the first pushing cylinder 13351, and the other end is connected to the side of the first closing piston 13356 toward the first pushing piston 13354, and the first closing piston 13356 is movably arranged in the first air outlet main pipe 1332.

[0052] The pushing medium 13353 is disposed in the first pushing hole 13350 .

[0053] Among them, the pushing medium 13353 is used to expand or contract in the first pushing cylinder 13351 under the influence of temperature, and then drive the first closing piston 13356 to move in the first air outlet pipe 1332 through the first pushing piston 13354 and the first connecting rod 13355, thereby opening or closing the first air outlet pipe 1332.

[0054] It can be understood that the first push cylinder 13351 is a component for placing the push medium 13353; for example, the first push cylinder 13351 can be a metal cylinder or a metal box. The first pusher 13352 is a component for opening or closing the first outlet main pipe 1332; for example, the first pusher 13352 can be a component composed of the first push piston 13354, the first connecting rod 13355 and the first closing piston 13356. For another example, the first pusher 13352 can also be a component connected to two pistons. The push medium 13353 is a component for sensing temperature and controlling the first pusher 13352 according to the temperature. For example, the pusher 13353 can be expanded graphite or carbon fiber reinforced epoxy resin (CFRP), etc.

[0055] In this way, the first switch element 1335 is composed of the first pushing cylinder 13351, the first pushing member 13352 and the pushing medium 13353; compared with the switch element composed of the motor and the valve, the above scheme can control the opening of the first air outlet main pipe 1332 according to the temperature of the compressed air, and can simplify the structure and reduce the cost.

[0056] In some embodiments, see Figures 1 to 3 The first 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 the diameter of the second branch pipe 13332. The first branch pipe 13331 is connected to the second branch pipe 13332, and the second branch pipe 13332 is connected to the first intake main pipe 1331. The second switch member 1336 includes a first elastic element 13361, a connecting plate 13362, a second connecting rod 13363 and a second closing piston 13364. Wherein: 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 .

[0057] The connecting plate 13362 is movably disposed 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 .

[0058] 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 .

[0059] The second closing piston 13364 is movably disposed in the first branch pipe 13331 , and the side wall of the second closing piston 13364 facing away from the second branch pipe 13332 is connected to the other end of the second connecting rod 13363 .

[0060] Among them, the first elastic element 13361 is used to drive the second closing piston 13364 to move toward the second branch pipe 13332 through the connecting plate 13362 and the second connecting rod 13363 when the first switch component 1335 opens the first air outlet main pipe 1332, thereby closing the first air outlet branch pipe 1333; the first elastic element 13361 is also used 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 switch component 1335 closes the first air outlet main pipe 1332, thereby opening the first air outlet branch pipe 1333.

[0061] It can be understood that the first elastic element 13361 is a device for providing force for the second closing piston 13364 to close the first outlet branch pipe 1333; for example, the first elastic element 13361 can be a spring or a rubber rope. The connecting plate 13362 is a component for connecting the spring; for example, the connecting plate 13362 can be a metal plate. The second closing piston 13364 is a component for opening or closing the first outlet branch 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.

[0062] With such arrangement, when the first switch 1335 opens the first outlet main pipe 1332, under the action of the restoring force of the first elastic element 13361, the second closing piston 13364 is driven to move toward the second branch pipe 13332 through the connecting plate 13362 and the second connecting rod 13363, thereby closing the first outlet branch pipe 1333; when the first switch 1335 closes the first outlet main 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 outlet branch pipe 1333. The second switch 1336 of the above scheme can ensure that the gas flow direction in the intercooler is single, so as to avoid the compressed air in two directions flowing in the air cooling channel 120 of the intercooler.

[0063] Optionally, in some embodiments, see Figures 1 to 4 The second conversion member 134 includes a second conversion body 1344 and a third switch member 1345. Wherein: The second conversion body 1344 includes a second air intake main pipe 1341 , a second air intake branch pipe 1342 , a second air outlet main pipe 1343 , and a conversion pipe 1346 . The conversion pipe 1346 connects the second air intake branch pipe 1342 with the second air outlet main pipe 1343 .

[0064] The third switch component 1345 is movably disposed in the water cooling channel 110 , and a sealing process is performed between the third switch component 1345 and the inner wall of the water cooling channel 110 .

[0065] The third switch 1345 is used to open or close the connection between the water cooling channel 110 and the second integrated pipe 132 . The third switch 1345 is also used to open or close the connection between the second integrated pipe 132 and the second connecting channel 301 .

[0066] It can be understood that the second conversion body 1344 is a component for connecting the second integrated pipe 132, the second connecting 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 mutually connected channels. The third switch member 1345 is a component for controlling the connection relationship between the water cooling channel 110 and the second integrated pipe 132 and the connection relationship between the second integrated pipe 132 and the second connecting 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.

[0067] In this way, a third switch 1345 is provided to control the connection relationship between the water-cooling channel 110 and the second integrated pipe 132, and the connection relationship between the second integrated pipe 132 and the second connecting channel 301; the switch status of the 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 opened, the other pipe is in a closed state.

[0068] Optionally, see Figures 1 to 4 The third switch member 1345 includes a second elastic element 13451 and a third push piston 13452. Wherein: The second elastic element 13451 is disposed in the second integrated tube 132 , and one end of the second elastic element 13451 is connected to the inner wall of the second integrated tube 132 .

[0069] The third pushing piston 13452 is movably disposed in the water-cooling channel 110 , and the third pushing piston 13452 and the inner wall of the water-cooling channel 110 are sealed.

[0070] 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 rope, etc.

[0071] In this way, the third switch member 1345 is formed by arranging the second elastic element 13451 and the third push piston 13452, so that when the compressed air only passes through the air cooling part 12, the third push 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 connecting channel 301; when the compressed air passes through the water cooling part 11 and the air cooling part 12 successively, the compressed air pushes the third push piston 13452 to open the water cooling channel 110 and close the second connecting channel 301. The above scheme can control the water cooling channel 110 and the second connecting channel 301 accordingly according to and using the flow direction of the compressed air, so as to ensure the direction of the compressed air outflow without the external kinetic energy.

[0072] In some embodiments, see Figures 1 to 4 The third push piston 13452 is configured as a trapezoidal piston, and its inclined surface is located toward the water cooling part 11, and its side toward the air cooling part 12 is lower than the side opposite thereto.

[0073] In this way, by setting the third push piston 13452 as a trapezoidal piston, the third push piston 13452 can close the second connecting channel 301 when the water cooling channel 110 is opened, and the third push piston 13452 can also open the second connecting channel 301 when the water cooling channel 110 is closed, thereby simplifying its structure, saving materials, and reducing its damage rate.

[0074] In some embodiments, see Figure 2 and Figure 3 The automobile intercooler 100 further includes a one-way valve 40 , which is disposed in the first integrated pipe 131 , and the passage direction of the one-way valve 40 is from the first conversion member 133 toward the air-cooling portion 12 .

[0075] In this configuration, a one-way valve 40 is provided in the first integrated pipe 131 to prevent the compressed air from returning to the turbocharger through the first integrated pipe 131 when the compressed air passes through the air cooling part 12 and the water cooling part 11 in sequence.

[0076] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
