Abstract
Description
Technical Field
[0001] This utility model belongs to the field of intercooler technology, specifically relating to a self-cleaning, anti-clogging intercooler airflow channel. Background Technology
[0002] In turbocharged systems, the intercooler, as a core heat dissipation component, directly impacts engine performance due to the unobstructed flow of its airflow channels. Traditional intercoolers commonly suffer from the problem of their internal airflow channels being easily clogged by impurities such as sand and sludge, leading to decreased cooling efficiency and increased turbocharger load. Currently...
[0003] Self-cleaning technologies often employ simultaneous backwashing across all channels. However, due to the dispersion of the flushing gas, the flushing pressure in a single channel is insufficient, resulting in limited cleaning effectiveness. For example, traditional backwashing structures do not selectively block the airflow channels, causing the gas flow to be dispersed in multiple channels, making it difficult to achieve a high-pressure flushing effect, especially in terms of removing sticky impurities. Utility Model Content
[0004] The purpose of this invention is to provide a self-cleaning, anti-clogging intercooler airflow channel that can concentrate flushing gas into the internal airflow channel for flushing, thereby improving the flushing effect of the internal airflow channel and reducing the phenomenon of blockage in the internal airflow channel.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] A self-cleaning, anti-clogging intercooler airflow channel includes an outlet chamber and an inlet chamber. An outlet pipe and a backwash pipe are fixedly connected to the outlet chamber. An inlet pipe is fixedly connected to the inlet chamber. Multiple gas flow pipes are fixedly connected between the outlet chamber and the inlet chamber. The inside of each gas flow pipe is an internal airflow channel connecting the outlet chamber and the inlet chamber. Multiple normally open pipe sealing mechanisms, each corresponding to a gas flow pipe, are fixedly connected inside both the outlet chamber and the inlet chamber.
[0007] The normally open pipe sealing mechanism does not seal the end opening of the internal airflow channel when it is in the open state;
[0008] The normally open pipe sealing mechanism seals the end opening of the internal airflow channel when it is in the closed state.
[0009] Furthermore, a first solenoid valve is fixedly connected to the air outlet pipe, a second solenoid valve is fixedly connected to the air inlet pipe, and a third solenoid valve is fixedly connected to the backwash pipe.
[0010] Furthermore, an inspection port is provided on the lower side of the air intake chamber, and an inspection plate adapted to the inspection port is detachably and fixedly connected to the lower side of the air intake chamber.
[0011] Furthermore, the normally open pipe sealing mechanism includes an electric telescopic mechanism fixedly connected inside the air outlet chamber or air inlet chamber, and a sealing plate opposite to the internal airflow channel is fixedly connected to the electric telescopic mechanism.
[0012] Furthermore, the electric telescopic mechanism includes a fixed frame fixedly connected inside the air outlet chamber or air inlet chamber. An electromagnet is fixedly connected to one end of the fixed frame away from the gas flow pipe. A pull rod is slidably connected to one end of the fixed frame near the gas flow pipe. One end of the pull rod is fixedly connected to a sealing plate. The other end of the pull rod is fixedly connected to a connecting plate slidably connected inside the fixed frame. A magnet is fixedly connected to the connecting plate. When the electromagnet is energized, the magnet and the magnet repel each other magnetically.
[0013] Furthermore, a tension spring is fixedly connected between the inner wall of the fixed frame away from the gas flow pipe and the connecting plate.
[0014] The technical effects achieved by this utility model are as follows:
[0015] This invention relates to a self-cleaning, anti-clogging intercooler airflow channel. By installing a normally open pipe sealing mechanism at the end of the gas flow pipe to seal the end opening of the internal airflow channel, the flushing gas can be concentrated and input into the channel to be cleaned for flushing. With a constant gas flow rate, the smaller the gas flow cross-section, the greater the flow pressure, thereby increasing the flushing pressure on the channel to be cleaned, improving the flushing effect, and reducing the phenomenon of blockage in the internal airflow channel.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0023] like Figures 1-4 As shown, a self-cleaning, anti-clogging intercooler airflow channel includes an outlet chamber 1 and an inlet chamber 2. An outlet pipe 4 connected to the outlet chamber 1 is fixedly connected to the outlet chamber 1, and an inlet pipe 5 connected to the inlet chamber 2 is fixedly connected to the inlet chamber 2. Multiple gas flow pipes 3 are fixedly connected between the outlet chamber 1 and the inlet chamber 2. The inside of the gas flow pipe 3 is an internal airflow channel connecting the outlet chamber 1 and the inlet chamber 2, and an external airflow channel is formed between two adjacent gas flow pipes 3.
[0024] High-temperature gas enters the intake chamber 2 through the intake pipe 5, then enters the exhaust chamber 1 through the inner airflow channel of the gas flow pipe 3, and is discharged through the exhaust pipe 4. During the flow of high-temperature gas inside the inner airflow channel, cold air from the outside is introduced through the outer airflow channel between adjacent gas flow pipes 3. This cold air exchanges heat with the high-temperature gas in the inner airflow channel through the pipe wall, thereby cooling the turbocharged gas and reducing its temperature.
[0025] In order to self-clean the internal airflow channel and reduce the blockage of the internal airflow channel, this technical solution has a backwash pipe 6 fixedly connected to the air outlet chamber 1 and communicating with the air outlet chamber 1. By inputting flushing gas into the backwash pipe 6, gas can be input into the air outlet chamber 1, so that the gas inside the air outlet chamber 1 flows back into the internal airflow channel and into the air inlet pipe 5 through the internal airflow channel, thereby realizing the backwashing of the internal airflow channel.
[0026] like Figures 1-2 As shown, a first solenoid valve 7 is fixedly connected to the outlet pipe 4, a second solenoid valve 8 is fixedly connected to the inlet pipe 5, and a third solenoid valve 9 is fixedly connected to the backflushing pipe 6. When the intercooler is in normal use, the third solenoid valve 9 is closed and the first solenoid valve 7 and the second solenoid valve 8 are opened, which allows the high-temperature gas to flow normally. When performing self-cleaning, the third solenoid valve 9 is opened and the first solenoid valve 7 and the second solenoid valve 8 are closed, which allows the gas to be backflushed and reduces the phenomenon of flushing gas being discharged through the inlet pipe 5. Thus, the airflow direction can be controlled by the first solenoid valve 7, the second solenoid valve 8, and the third solenoid valve 9.
[0027] An inspection port is provided on the lower side of the air inlet chamber 2. When the flushing gas flushes the internal airflow channel, the gas that enters the air inlet chamber 2 after flushing can be discharged through the inspection port, reducing the phenomenon of air blockage. Furthermore, impurities that enter the air inlet chamber 2 through the flushing gas can be discharged through the inspection port.
[0028] like Figures 2-3 As shown, a maintenance plate 10 that is compatible with the maintenance port is detachably fixedly connected to the lower side of the intake chamber 2. The maintenance plate 10 can be fixedly connected with screws to seal the maintenance port and reduce the leakage of the maintenance port when the intercooler is in normal use. A sealing gasket can be fixedly connected to the upper side of the maintenance plate 10 to ensure the sealing performance when the maintenance port is blocked.
[0029] like Figures 2-3 As shown, both the exhaust chamber 1 and the intake chamber 2 are fixedly connected with multiple normally open pipe sealing mechanisms 11 that are one-to-one with the gas flow pipe 3. The normally open pipe sealing mechanism 11 can seal the end opening of the internal airflow channel.
[0030] At this time, when flushing and cleaning the internal airflow channels, one of the internal airflow channels is selected as the channel to be cleaned. The normally open pipe sealing mechanism 11 opposite to the channel to be cleaned is in the open state, and the other normally open pipe sealing mechanisms 11 are in the closed state. The ends of the remaining internal airflow channels are blocked. Then, flushing gas is input through the backwash pipe 6. The flushing gas can be concentrated and input into the channel to be cleaned to flush the channel. With the gas flow rate remaining constant, the smaller the gas flow cross section, the greater the flow pressure, thereby increasing the flushing pressure on the channel to be cleaned and improving the flushing effect on the channel to be cleaned.
[0031] Specifically, such as Figures 2-4 As shown, the normally open pipe sealing mechanism 11 includes an electric telescopic mechanism fixedly connected inside the air outlet chamber 1 or the air inlet chamber 2. A sealing plate 17 opposite to the internal airflow channel is fixedly connected to the electric telescopic mechanism. When the sealing plate 17 abuts against the port of the internal airflow channel, the internal airflow channel can be sealed, that is, the normally open pipe sealing mechanism 11 is in the closed state. When the sealing plate 17 separates from the port of the internal airflow channel, the seal on the internal airflow channel is released, that is, the normally open pipe sealing mechanism 11 is in the open state.
[0032] Meanwhile, a rubber sealing gasket 18 can be fixedly connected to the side of the sealing plate 17, which can improve the sealing between the sealing plate 17 and the gas flow pipe 3.
[0033] It should be noted that when the normally open pipe sealing mechanism 11 is in the open state, the distance between the rubber sealing gasket 18 and the port of the inner airflow channel is preferably greater than the cross-sectional height of the inner airflow channel to ensure the air intake effect.
[0034] The electric telescopic mechanism includes a fixed frame 12 fixedly connected inside the air outlet chamber 1 or the air inlet chamber 2. An electromagnet 15 is fixedly connected to one end of the fixed frame 12 away from the gas flow pipe 3. A pull rod 13 is slidably connected to one end of the fixed frame 12 near the gas flow pipe 3. One end of the pull rod 13 is fixedly connected to a sealing plate 17. The other end of the pull rod 13 is fixedly connected to a connecting plate 14 slidably connected inside the fixed frame 12. A magnet 16 is fixedly connected to the connecting plate 14. When the electromagnet 15 is energized by an external power source, it releases the magnetic force that repels the magnet 16, pushing the magnet 16 and causing the sealing plate 17 to move toward the gas flow pipe 3 until the rubber sealing gasket 18 abuts against the port of the inner air flow channel, thus sealing the port of the inner air flow channel.
[0035] Specifically, the fixed frame 12, pull rod 13, and connecting plate 14 are preferably made of non-magnetic rigid materials, such as high-temperature resistant engineering plastics, carbon fiber, or non-magnetic steel, to reduce the phenomenon of the pull rod 13 and connecting plate 14 being accidentally pulled by the electromagnet 15. The magnet block 16 can be made of iron.
[0036] A tension spring 19 can also be fixedly connected between the inner wall of the fixed frame 12 away from the gas flow pipe 3 and the connecting plate 14. When the electromagnet 15 is de-energized, the tension spring 19 drives the sealing plate 17 to move, so that the rubber sealing gasket 18 and the inner airflow channel port are effectively separated, thereby reducing the phenomenon of the sealing plate 17 and the rubber sealing gasket 18 blocking the inner airflow channel port.
[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
