Description

Technical Field

[0001] The utility model relates to the technical field of supercharger equipment, in particular to a supercharger volute heat dissipation device. Background Technique

[0002] An automotive turbocharger mainly uses the inertial impulse of the exhaust gas discharged from the engine to drive the turbine in the turbine chamber. The turbine drives the coaxial impeller, and the impeller compresses and delivers the air sent by the air filter pipeline, so that it is pressurized and enters the cylinder. When the engine speed increases, the exhaust gas discharge speed also increases synchronously. However, the exhaust gas temperature is relatively high, and heat is also released when high-pressure compressed gas is used. This makes the supercharger extremely hot during operation and requires a heat dissipation device for heat dissipation.

[0003] A Chinese patent with the publication number CN217926008U discloses a high-strength supercharger turbine housing, including a housing main body. Heat dissipation devices are arranged on both sides of the housing main body. The heat dissipation device includes a cylinder. The cylinder and the side surface of the housing main body form a heat dissipation cavity. A ventilation pipe is constructed inside the cylinder. A fan blade for delivering air to the heat dissipation cavity is installed inside the ventilation pipe. A transverse plate is constructed inside the ventilation pipe. A motor is installed in the middle of the transverse plate. A fan blade is installed on the motor. And a dust-proof net is installed at one end of the ventilation pipe away from the housing main body. Circular pipes are symmetrically installed on the side surface of the housing main body. A short pipe is constructed on the outer edge surface of the circular pipe. An opening for abutting against the outer edge surface of the short pipe is opened inside the cylinder. A thread is provided on the inner edge surface of the short pipe. This high-strength supercharger turbine housing can accelerate the heat dissipation of the device and avoid the phenomenon of device damage caused by overheating.

[0004] In the above technology, by installing a dust-proof net, although the entry of dust into the interior of the turbine housing can be reduced, during the process of heat discharge, the dust in the heat and the oil fume emitted by the automotive engine are very likely to adhere to the inner wall of the dust-proof net, blocking the dust-proof net.

[0027] The following further illustrates the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0028] Refer to Figure 1 - Figure 6 As shown, a supercharger volute heat dissipation device of the present utility model includes a housing 1, a fixed frame 5 is fixedly connected to the inner wall of the housing 1, a motor 3 is fixedly connected to the fixed frame 5, the output shaft of the motor 3 is rotatably connected to the fixed frame 5 through a bearing, and a rotating shaft 6 is fixedly connected thereto, and a turbine body 4 is fixedly connected to the rotating shaft 6; a tooth disc 7 is fixedly connected to the rotating shaft 6; four dust-proof nets 9 are fixedly connected to the housing 1, and a scraper 10 is rotatably connected to each dust-proof net 9 through a rotating shaft, and each scraper 10 is in contact with the dust-proof net 9; gears 11 are fixedly connected to the ends of the rotating shafts far from the scrapers 10, and the gears 11 are all meshed with the tooth disc 7.

[0029] During operation, to solve the problem of reduced heat dissipation efficiency caused by untimely cleaning of the dust on the dust-proof net 9, when the supercharger is working, by turning on the motor 3, the output shaft of the motor 3 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the turbine body 4 to rotate, and the turbine drives the coaxial impeller. The impeller compresses the air sent by the air filter pipeline and makes it enter the cylinder under pressure; during the rotation of the rotating shaft 6, by driving the tooth disc 7 to rotate, the tooth disc 7 drives the gear 11 to rotate, the gear 11 drives the connected rotating shaft and the scraper 10 to rotate, and the scraper 10 is always in contact with the dust-proof net 9 during rotation, scraping off the dust on the inner wall of the dust-proof net 9, preventing the dust from adhering to the dust-proof net 9 and blocking the dust-proof net 9, realizing the function of quickly cleaning the dust-proof net 9 and ensuring the normal heat dissipation.

[0030] Furthermore, as Figure 3 、 Figure 4 and Figure 6As shown in the figure, one end of the housing 1 is connected and fixed with an air outlet pipe 15. An outer shell 2 is fixedly connected to the outside of the housing 1. A spray chamber 12 is formed between the outer shell 2, the air outlet pipe 15 and the housing 1. A water tank 21 is fixedly connected to the top of the outer shell 2. A water outlet pipe 23 is connected and fixed to the bottom of the water tank 21. One end of the water outlet pipe 23 passes through the housing 1 and extends into the spray chamber 12. One end of the water outlet pipe 23 is connected and fixed with a delivery pipe 25. The delivery pipe 25 is fixedly connected to the inner wall of the spray chamber 12 through a fixing sleeve. A plurality of spray pipes 26 are connected and fixed to the bottom of the delivery chamber. The spray pipes 26 are respectively arranged above the air outlet pipe 15 and the housing 1. A cooler 22 and a water pump are successively installed on the water outlet pipe 23. The cooler 22 and the water pump are both fixedly connected to the outer side wall of the outer shell 2.

[0031] During operation, when heat dissipation of the housing 1 is required, the cooler 22 and the water pump are turned on. The water in the water tank 21 is pumped out by the water pump. The water in the water tank 21 is quickly cooled by the cooler 22. The cold water is transported to the delivery pipe 25 through the water outlet pipe 23. The water in the delivery pipe 25 is sprayed on the air outlet pipe 15 and the housing 1 through the spray pipes 26. The air outlet pipe 15 and the housing 1 are quickly cooled by the cold air refrigeration, which is beneficial to quickly dissipate the heat in the housing 1.

[0032] Further, as Figure 3 shown, a water inlet pipe 24 is connected and fixed to the bottom of the water tank 21. One end of the water inlet pipe 24 is arranged at the bottom end of the spray chamber 12. A water pump is installed on the water inlet pipe 24.

[0033] During operation, the water for spray cooling finally flows to the bottom of the spray chamber 12. By turning on the water pump on the water inlet pipe 24, the water in the spray chamber 12 is pumped back into the water tank 21, realizing the recycling of water, preventing the accumulation of water in the spray chamber 12, and the flowing and circulating water improves the heat dissipation effect.

[0034] Further, as Figure 1 and Figure 3 shown, one end of the air outlet pipe 15 far away from the housing 1 is slidably connected with a silencing pipe 16. A silencing cotton 17 is fixedly connected to one end of the silencing pipe 16. Two limiting columns 20 are symmetrically fixedly connected to the other end of the silencing pipe 16. Two limiting grooves 19 are formed on the air outlet pipe 15. A spring 18 is fixedly connected to the inside of the air outlet pipe 15. One end of the spring 18 is fixedly connected to the air outlet pipe 15.

[0035] During operation, to reduce the noise during the air outlet process, by setting the silencing pipe 16 and sound-absorbing cotton 17, part of the noise is absorbed to reduce the impact of the noise on the environment; when installing the silencing pipe 16, the limiting post 20 needs to be aligned with the limiting groove 19 and enter the air outlet pipe 15. The silencing pipe 16 presses against the spring 18, and the spring 18 is compressed. The silencing pipe 16 slides into the air outlet pipe 15, and then by rotating the silencing pipe 16, the limiting post 20 is inserted and sleeved with the innermost side of the limiting groove 19. Under the action of the limiting groove 19 and the spring 18, the limiting post 20 and the silencing pipe 16 are fixed to achieve the installation of the silencing pipe 16.

[0036] Furthermore, as Figure 2 shown, a connecting pipe 13 is fixedly connected to one end of the housing 1 away from the motor 3, and a plurality of fins 14 are fixedly connected to the outer wall of the connecting pipe 13; a flange is fixedly connected to the connecting pipe 13.

[0037] During operation, when installing this supercharger, it needs to be connected through the flange on the connecting pipe 13. When heat accumulates on the connecting pipe 13, the heat dissipation area is increased through the fins 14 to improve the heat dissipation speed.

[0038] Furthermore, as Figure 5 shown, a fan blade 8 is provided between the gear 11 and the scraper 10, and the fan blade 8 is fixedly connected to the rotating shaft.

[0039] During operation, by setting the fan blade 8, when the gear 11 rotates, it drives the connected rotating shaft, fan blade 8 and scraper 10 to rotate. The heat in the housing 1 is quickly discharged through the dust-proof net 9 by the fan blade 8 to improve the heat dissipation speed.

[0040] Furthermore, as Figure 3 shown, a wear-resistant layer is provided on the inner wall of the housing 1, and the wear-resistant layer is a nylon wear-resistant layer.

[0041] During operation, a nylon wear-resistant layer is provided inside the housing 1 to reduce the damage to the inner wall of the housing 1 during casting.

[0042] Furthermore, as Figure 1 shown, the housing 1 is made of austenitic heat-resistant ductile iron material, and the outer shell 2 is made of aluminum alloy material.

[0043] During operation, the housing 1 is made of austenitic heat-resistant ductile iron material. Austenitic heat-resistant ductile iron obtains a stable austenite matrix through alloying, improving the high-temperature stability of the material. At the same time, austenitic heat-resistant ductile iron not only has excellent high-temperature tissue stability and oxidation resistance, but also has good casting performance; the aluminum alloy outer shell 2 improves the thermal conductivity.

[0044] Working principle: To solve the problem that the heat dissipation efficiency is reduced due to the failure to clean the dust on the dust filter net 9 in a timely manner, when the supercharger works, the motor 3 is turned on, the output shaft of the motor 3 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the turbine body 4 to rotate, and the turbine drives the coaxial impeller. The impeller compresses the air sent by the air filter pipeline and makes it enter the cylinder under pressure; during the rotation of the rotating shaft 6, the toothed disk 7 is driven to rotate, the toothed disk 7 drives the gear 11 to rotate, the gear 11 drives the connected rotating shaft and the scraper 10 to rotate, and the scraper 10 always contacts the dust filter net 9 during rotation, scraping off the dust on the inner wall of the dust filter net 9, preventing the dust from adhering to the dust filter net 9 and blocking the dust filter net 9, realizing the function of quickly cleaning the dust filter net 9 and ensuring the normal heat dissipation; when the rotating shaft rotates, the fan blade 8 is driven to rotate, and the heat in the housing 1 is quickly discharged through the dust filter net 9 by the fan blade 8, improving the heat dissipation speed;

[0045] When heat dissipation of the housing 1 is required, the refrigerator 22 and the water pump are turned on. The water pump pumps out the water in the water tank 21, and the refrigerator 22 quickly cools the water in the water tank 21. The cold water is transported to the delivery pipe 25 through the outlet pipe 23, and the water in the delivery pipe 25 is sprayed on the air outlet pipe 15 and the housing 1 through the spray pipe 26. The air outlet pipe 15 and the housing 1 are quickly cooled by the cold air refrigeration, which is beneficial to quickly dissipate the heat in the housing 1; the water for spray cooling finally flows to the bottom of the spray cavity 12. By turning on the water pump on the inlet pipe 24, the water in the spray cavity 12 is pumped back into the water tank 21, realizing the recycling of water, preventing the accumulation of water in the spray cavity 12, and the flowing and circulating water improves the heat dissipation effect;

[0046] To reduce the noise during the air outlet process, by setting the sound-absorbing pipe 16 and the sound-absorbing cotton 17, part of the noise is absorbed, reducing the impact of the noise on the environment; when installing the sound-absorbing pipe 16, the limit post 20 needs to be aligned with the limit groove 19 and enter the air outlet pipe 15. The sound-absorbing pipe 16 presses the spring 18, the spring 18 is compressed, and the sound-absorbing pipe 16 slides into the air outlet pipe 15. Then, by rotating the sound-absorbing pipe 16, the limit post 20 is inserted and sleeved with the innermost side of the limit groove 19. Under the action of the limit groove 19 and the spring 18, the limit post 20 and the sound-absorbing pipe 16 are fixed, realizing the installation of the sound-absorbing pipe 16.

[0047] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
