Description

Technical Field

[0001] This utility model relates to the field of turbocharger technology, and more specifically, to a cooling mechanism for a turbocharger. Background Technology

[0002] Currently, the temperature of automotive turbochargers is generally above 600 degrees Celsius. After being pressurized by the turbocharger, the air temperature becomes higher and its volume increases. If an intercooler is missing and the high-temperature pressurized air is allowed to enter the engine directly, the excessively high air temperature can cause engine knocking or even damage and stalling.

[0003] While existing cooling mechanisms have radiators to dissipate heat after cooling the equipment, they lack ventilation holes, thus failing to effectively address the cooling problem.

[0004] A search revealed that Chinese Patent No. CN219932306U discloses a cooling device for turbochargers. This utility model uses a protective mesh in the main body of the indicator to filter the incoming air, and a protective shell to protect against impacts.

[0005] However, in actual use, the above-mentioned cooling device can cause the compressor chamber of the turbocharger to overheat, resulting in excessively high air temperature during air compression, which reduces the air compression density and thus reduces the air compression efficiency of the turbocharger. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cooling mechanism for a turbocharger to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cooling mechanism for a turbocharger includes a turbocharger body. A first connecting flange is fixedly connected to one side of the turbocharger body, and a second connecting flange is fixedly connected to the other side of the turbocharger body. A compression chamber is provided on one side of the turbocharger body. A flow guide groove is formed on the inner side of the turbocharger body, and a cooling mechanism is provided on the outer side of the turbocharger body. The cooling mechanism includes two positioning brackets. One side of each positioning bracket is fixedly connected to the outer side of the turbocharger body, and the inner side of each positioning bracket communicates with one end of the flow guide groove. A slot is formed on the inner side of each positioning bracket, and a sealing strip is fixedly connected inside each positioning bracket. The turbocharger body... A connecting frame is fixedly connected to the side, a water tank is fixedly connected to the inner side of the connecting frame, a water pump is fixedly connected to the top of the water tank, an outlet pipe is fixedly connected to the output end of the water pump, an inlet pipe is fixedly connected to the top of the water tank, a connecting seat is fixedly connected to one end of both the outlet and inlet pipes, a bend is opened on the inner side of the connecting seat, the outer side of the connecting seat is snapped into the inner side of the slot, a liquid filling pipe is fixedly connected to the top of the water tank, a cavity is fixedly connected to the inner side of the water tank, one end of the cavity is fixedly connected to the input end of the water pump, two fans are fixedly connected to one side of the water tank, a filter plate is fixedly connected to the outer side of the water tank; a sealing mechanism is provided on the outer side of the connecting flange one and connecting flange two.

[0009] By adopting the above technical solution, the coolant inside the water tank is pumped to the inside of the guide channel by a water pump, and the turbocharger body and the inside of the compression chamber are cooled through the guide channel, thereby improving the compressed air efficiency of the turbocharger body.

[0010] As a further description of the above technical solution: the sealing mechanism includes multiple rotating frames, one side of which is hinged to the outside of connecting flange one and connecting flange two, a clamping frame is fixedly connected to one side of the rotating frame, a sealing ring one is fixedly connected to the outside of connecting flange two, a slot one is provided on one side of the sealing ring one, a sealing ring two is fixedly connected to one side of connecting flange one, and a slot two is provided on one side of the sealing ring two.

[0011] By adopting the above technical solution, the connection gaps between the connecting flanges and the external pipeline are filled by sealing ring 2, slot 2 and sealing ring 1, slot 1 and connecting flange 2, and the connection is limited by multiple rotating frames and clamping frames, so that the turbocharger body has better sealing performance during operation.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a cooling mechanism, compared with the existing technology, the coolant can flow through the turbocharger body on one side of the compression chamber by using the guide channel, which conducts heat away from the temperature accumulated inside the turbocharger body, reduces the accumulation of heat inside the turbocharger body, reduces the temperature rise of the compressed air, and thus the turbocharger body can compress air better and improve the air compression efficiency of the turbocharger body.

[0014] 2. By setting up a sealing mechanism, compared with the existing technology, multiple clamping frames are used to limit the connection of the external pipe flanges of the connecting flange one and the connecting flange two, so that the connection is further limited. At the same time, the sealing ring one, the slot one, the sealing ring two and the slot two are used to deform and fill the connection gap, thereby maintaining the connection sealing between the turbocharger body and the external pipe and reducing gas leakage caused by vibration.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The embodiments disclosed in this application are as follows: Figure 1-6 The cooling mechanism for a turbocharger shown includes a turbocharger body 1, a connecting flange 2 fixedly connected to one side of the turbocharger body 1, a connecting flange 3 fixedly connected to the other side of the turbocharger body 1, a compression chamber 4 provided on one side of the turbocharger body 1, a guide groove 5 opened on the inner side of the turbocharger body 1, and a cooling mechanism provided on the outer side of the turbocharger body 1. The cooling mechanism includes two positioning frames 6, one side of the positioning frame 6 is fixedly connected to the outer side of the turbocharger body 1, the inner side of the positioning frame 6 is connected to one end of the guide groove 5, a slot 7 is opened on the inner side of the positioning frame 6, a sealing strip 8 is fixedly connected inside the positioning frame 6, a connecting frame 9 is fixedly connected to one side of the turbocharger body 1, a water tank 10 is fixedly connected to the inner side of the connecting frame 9, a water pump 11 is fixedly connected to the top of the water tank 10, and a water outlet pipe 12 is fixedly connected to the output end of the water pump 11. The water tank 10 is fixedly connected to an inlet pipe 13. A connecting seat 24 is fixedly connected to one end of both the outlet pipe 12 and the inlet pipe 13. A bend 25 is provided inside the connecting seat 24. The outer side of the connecting seat 24 engages with the inner side of the slot 7. A liquid filling pipe 14 is fixedly connected to the top of the water tank 10. A cavity 15 is fixedly connected to the inner side of the water tank 10. One end of the cavity 15 is fixedly connected to the input end of the water pump 11. Two fans 16 are fixedly connected to one side of the water tank 10. A filter plate 17 is fixedly connected to the outer side of the water tank 10. Sealing mechanisms are provided on the outer sides of the connecting flange 12 and the connecting flange 23. The water pump 11 delivers coolant sequentially through the bend 25, the outlet pipe 12, the guide channel 5, and the inlet pipe 13, allowing the coolant to carry away some of the accumulated heat inside the turbocharger body 1 and the compression chamber 4, thereby reducing the temperature inside the compression chamber 4 and thus reducing the temperature of the incoming air, resulting in better air compression.

[0024] Reference Figure 1 , Figure 3 and Figure 5As shown, the sealing mechanism includes multiple rotating frames 18. One side of the rotating frame 18 is hinged to the outside of the connecting flange 1 2 and the connecting flange 2 3. A clamping frame 19 is fixedly connected to one side of the rotating frame 18. A sealing ring 1 20 is fixedly connected to the outside of the connecting flange 2 3. A slot 1 21 is opened on one side of the sealing ring 1 20. A sealing ring 2 22 is fixedly connected to one side of the connecting flange 1 2. A slot 2 23 is opened on one side of the sealing ring 2 22. By rotating the multiple rotating frames 18 and the clamping frame 19, the corresponding external pipe connecting flanges are limited and then fixed by bolts. At the same time, the sealing ring 1 20, the slot 1 21, the sealing ring 2 22 and the slot 2 23 are used to squeeze and seal the connection gap between the connecting flange 1 2 and the connecting flange 2 3.

[0025] The working principle of this utility model is as follows: When cooling the turbocharger body 1 during use, coolant is first injected into the water tank 10 through the filler pipe 14 for storage. Then, the water pump 11 allows the cavity 15 to transport the coolant from the inside of the water tank 10, so that the coolant enters the outlet pipe 12 through the cavity 15. At the same time, two fans 16 are activated to blow air onto the surface of the cavity 15 to lower the temperature of the coolant. Afterward, the coolant enters the positioning frame 6 through the connecting seat 24 on one side of the outlet pipe 12 and the cavity 15, and passes through the positioning frame 6. The coolant enters the guide channel 5 and then moves along the guide channel 5 from one side of the turbocharger body 1 to the position of another positioning bracket 6. During the movement of the coolant, it will carry away the heat accumulated inside the turbocharger body 1. Then the coolant enters the water inlet pipe 13 through the other positioning bracket 6, cavity 15 and connecting seat 24, and then returns to the water tank 10 through the water inlet pipe 13 to complete the circulation of the coolant. The connecting seat 24 can be engaged with the slot 7 to allow the sealing strip 8 to effectively compress and seal between the connecting seat 24 and the positioning bracket 6.

[0026] During the operation of the turbocharger body 1, multiple rotating frames 18 and clamping frames 19 on the outside of connecting flange 1 2 and connecting flange 2 3 limit the connected flanges, and the corresponding sealing ring 1 20, slot 1 21, sealing ring 2 22 and slot 2 23 seal the gaps at the connection, thereby maintaining good sealing between the turbocharger body 1 and the external pipeline.
