Description

Technical Field

[0001] This utility model relates to the technical field of automotive EGR coolers, and specifically to a cooler with a floating connection. Background Technology

[0002] The EGR cooler is a core component of the Exhaust Gas Recirculation (EGR) system, primarily used to reduce exhaust gas temperature and decrease nitrogen oxide emissions. Its working principle involves cooling the high-temperature exhaust gas to approximately 150 degrees Celsius using water or air cooling, thereby improving oxygen mixing efficiency.

[0003] Its structure is greatly affected by the vehicle's assembly space. The installation space varies on different types of vehicles, especially since it needs to connect intake pipes, exhaust pipes, water inlet pipes, and water outlet pipes. Therefore, its external pipe connections are numerous and complex. This poses a challenge to the assembly of the cooler body.

[0004] The existing EGR cooler uses an integrated structure for the water inlet pipe, which is mounted on the cooler body. The water supply pipe joint is fixed by threaded pipe connection. Therefore, when it is installed on a car, the vibration of the car is often transmitted to the water supply pipe, causing this rigid connection to resonate. This can easily cause the connection to loosen in minor cases, and in severe cases, it can cause the pipe connection to break or leak.

[0005] Based on the above problems, the existing structure needs to be improved. Utility Model Content

[0006] In order to solve the technical problems and shortcomings of the prior art, the present invention provides a cooler with a floating connection that can overcome the adverse effects of vibration during vehicle operation and extend its service life.

[0007] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0008] A cooler with a floating connection includes a cooler body, which includes a rectangular outer shell and a cooling inner core that divides the inner cavity of the outer shell into a water chamber and an air chamber. One end of the outer shell is provided with an air inlet hood for connecting to the air chamber, and the other end of the outer shell is provided with an air outlet hood for connecting to the air chamber. The top of the outer shell is provided with an opening, and a floating female insertion tube is welded at the opening. One end of the floating female insertion tube is connected to a floating male insertion tube. The end of the floating female insertion tube is provided with a long flared end for the floating male insertion tube to be inserted. Floating heads are respectively provided at both ends of the floating male insertion tube. A sealing groove is provided on the outer peripheral wall of the floating head for the sealing ring to cooperate with. The floating male insertion tube forms a swing clearance groove between the two floating heads.

[0009] Preferably, the inlet of the floating female cannula is provided with a flared curved surface, which is adapted to the groove surface of the swing relief groove.

[0010] Preferably, the floating head slides or swings axially on the floating female cannula, and the swing of the floating head is limited on the flared curved surface.

[0011] Preferably, the rear end of the floating female insertion tube is connected to a small tube, and a water outlet pipe is provided on the lower side of the outer shell.

[0012] Preferably, a distance detector is provided between the floating female cannula and the floating male cannula, the distance detector being used to detect the distance between the horizontal movement of the floating female cannula and the floating male cannula.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model has a floating female insertion tube set at the top opening of the outer shell, which can be adapted to a floating male insertion tube. In the water circuit design, the pipe can be floated. The floating male insertion tube can swing or move its axis on the floating female insertion tube to overcome the impact caused by vibration, making the water supply here more stable and reliable and less prone to damage. At the same time, the sealing ring is used to achieve a seal, which is also very easy and convenient for maintenance and repair.

[0015] 2. This utility model utilizes the design of the flared curved surface to limit the floating male insertion tube, which not only provides a better and more complete mating surface during the swinging process, but also makes it less likely for the floating head to swing excessively.

[0016] 3. The floating female and floating male tubes are located on the top of the outer casing, making them easy to inspect and disassemble. Excess water is diverted and utilized using small tubes. After heat exchange on the cooling core by injecting cold water, the hot water is relatively easy to stratify and stay on top, at which point it can be diverted through small tubes.

[0017] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0030] Example 1:

[0031] This invention discloses a cooler with a floating connection, as described in the embodiments below. Figure 1 , Figure 4 and Figure 5 As shown, it includes a cooler body. The cooler body includes a rectangular outer shell 1 and a cooling inner core 2 that divides the inner cavity of the outer shell 1 into a water chamber 21 and an air chamber 22. One end of the outer shell 1 is provided with an air inlet shroud 3 for communicating with the air chamber 22, and the other end of the outer shell 1 is provided with an air outlet shroud 4 for communicating with the air chamber 22.

[0032] Combined Figure 2 and Figure 3 An opening 11 is provided at the top of the outer shell 1. A floating female insertion tube 5 is welded at the opening 11. One end of the floating female insertion tube 5 is connected to a floating male insertion tube 6. The end of the floating female insertion tube 5 is provided with a long flared end 51 for the floating male insertion tube 6 to be inserted. Floating heads 61 are provided at both ends of the floating male insertion tube 6. A sealing groove 62 is provided on the outer peripheral wall of the floating head 61. The sealing groove 62 is used for the sealing ring 63 to cooperate. A swing clearance groove 64 is formed between the two floating heads 61 of the floating male insertion tube 6.

[0033] Based on the above scheme, the design principle of this scheme is as follows: a floating female insertion tube 5 is set at the top opening 11 of the outer shell 1, which can be adapted to the floating male insertion tube 6. In the water circuit design, the floating connection of the pipeline is realized. The floating male insertion tube 6 can swing or move its axis on the floating female insertion tube 5 to overcome the impact caused by vibration, making the water supply here more stable and reliable and less prone to damage. At the same time, the sealing ring 63 is used to achieve sealing, which is also very easy and convenient for maintenance and repair.

[0034] In this embodiment, the inlet of the floating female cannula 5 is provided with a flared curved surface 52, which is adapted to the groove surface of the swing relief groove 64. The floating head 61 slides or swings axially on the floating female cannula 5, and the swing of the floating head 61 is limited on the flared curved surface 52. By using the design of the flared curved surface 52 to limit the floating male cannula 6, not only is there a better and more sufficient mating surface during the swing, but the floating head 61 is also less likely to swing excessively.

[0035] In addition, a small tube 53 is connected to the rear end of the floating female insertion tube 5, and a water outlet tube 7 is provided on the lower side of the outer casing 1. The floating female insertion tube 5 and the floating male insertion tube 6 are fitted on the upper part of the outer casing 1, which is easy to inspect and disassemble. The small tube 53 is used to divert excess water for reuse. After heat exchange on the cooling inner core 2 by injecting cold water, the hot water is relatively easy to stratify and stay on the top. At this time, it can be diverted through the small tube 53.

[0036] Example 2:

[0037] Based on the above implementation example, further optimization is possible, see reference. Figure 6 As shown, a distance detector 8 is disposed between the floating female cannula 5 and the floating male cannula 6. The distance detector 8 is used to detect the distance between the horizontally moving floating female cannula 5 and the floating male cannula 6. The distance detector 8 can be a Hall sensor, which can detect the approach and departure of a magnet. It should be noted that, in order to cooperate with the distance detection, a magnetic ring 9 is disposed on the inner side of the port of the floating male cannula 6. The magnetic ring 9 and the Hall sensor work together to form the distance detector 8. A detection signal can be sent through this structure. In other embodiments, the distance detector 8 can be a limit switch or the like.

The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations.
