Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts, and specifically relates to a turbocharger oil cooling and pressure maintaining device. Background Art

[0002] In a turbocharger, there is high-speed relative motion between moving parts and important components such as the turbine impeller, compressor impeller, and rotor shaft and the supercharger housing. Under the action of oil pressure, a double-layer oil film is formed between these components, and the rotor actually floats on the oil film and thus rotates at high speed. Due to the extremely high speed and temperature, there are also extremely high requirements for lubrication and cooling.

[0003] If the lubrication and cooling of the supercharger are insufficient, it will cause severe wear of the bearings, the service life of the bearings will be severely shortened, the gap between the rotor and the casing will be increased, and part of the oil will enter the intake pipe or exhaust pipe from this part, resulting in serious fuel combustion failure. Poor heat dissipation will cause the oil to coke or carbonize.

[0004] Poor heat dissipation will cause the oil to coke or carbonize, further damaging the seal and lubrication of the supercharger, exacerbating wear, and causing the supercharger to leak oil or make abnormal noises, or even serious jamming.

[0005] In order to cool and lubricate the turbocharger, the oil pipe is specifically separated from the main oil path of the engine lubrication system, so that the oil enters from the oil inlet in the middle of the turbocharger and flows out from the oil outlet below the middle to the middle. The rotor and bearings of the turbocharger are lubricated and cooled.

[0006] In order to ensure good lubrication and cooling effects, the flow rate of this oil is very fast and the flow rate is relatively large. In order to better cool the supercharger, the present invention provides a turbocharger oil cooling and pressure maintaining device, which uses a heat dissipation method combining air cooling and water cooling to accelerate the heat dissipation process of the oil supply pipe and improve the heat dissipation efficiency.

[0015] Furthermore, an air guide box is installed on the outside of the connection point between the delivery pipe and the turbocharger oil circuit.

Detailed implementation manners

[0031] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0032] As Figures 1 to 3 shown, the following preferred technical solutions are provided:

[0033] A turbocharger oil heat dissipation and pressure maintaining device, which is connected to the oil filter cooler 4, includes: a heat dissipation component 1 and a pressure maintaining component 2. The heat dissipation component 1 and the pressure maintaining component 2 are both installed on one side of the turbocharger through the main frame 3. The pressure maintaining component 2 is installed inside the heat dissipation component 1. The heat dissipation component 1 includes a heat dissipation pipe 1a and a cooling fan 1e. The heat dissipation pipe 1a is rotatably installed on the main frame 3 through the pipe rack 3b. The cooling fan 1e is installed at the lower end of the main frame 3 and faces the pipe body of the heat dissipation pipe 1a. An absorbent cotton group 1c is arranged outside the upper part of the heat dissipation pipe 1a. The heat dissipation pipe 1a is driven to rotate through the drive motor 1d. The drive motor 1d is installed on one side of the main frame 3 through the motor base 1d2. The pressure maintaining component 2 can be communicated with the oil circuit of the turbocharger.

[0034] Specifically, in order to solve the technical problem of dissipating heat from the oil entering the turbocharger while ensuring the oil supply pressure of the turbocharger, the present invention adds a heat dissipation and pressure maintaining device between the oil filter cooler 4 and the turbocharger to further dissipate heat from the oil entering the turbocharger, and stabilizes the input oil through the pressure maintaining component 2 to ensure the oil supply pressure. By using a heat dissipation method combining air cooling and water cooling, the heat dissipation process of the oil supply pipe is accelerated, and the heat dissipation efficiency is improved.

[0035] like Figures 2 to 9 As shown, the following preferred technical solutions are provided:

[0036] The heat dissipation pipe 1a includes a corrugated outer tube 1a2 and an inner tube 1a1 that can be connected to the pressure maintaining component 2. The corrugated outer tube 1a2 can be rotatably installed on the pipe rack 3b of the main frame 3. One end of the pressure maintaining component 2 is installed in the corrugated outer tube 1a2 through the inner tube 1a1. The inner tube 1a1 is located in the end of the corrugated outer tube 1a2 that is connected to the pressure maintaining component 2. The inner tube 1a1 and the corrugated outer tube 1a2 are integrally formed to form the heat dissipation pipe 1a. The end of the corrugated outer tube 1a2 away from the inner tube 1a1 is transmission-connected to the drive motor 1d through the pipe head 1a3. The corrugated outer tube 1a2 can be clamped with the water-absorbing sponge group 1c.

[0037] The pipe head 1a3 is fixedly arranged at one end of the corrugated outer tube 1a2 away from the inner tube 1a1. The pipe head 1a3 can be connected with the corrugated outer tube 1a2 and the oil filter cooler 4. A pulley groove 1a4 is arranged on the pipe head 1a3. The driving motor 1d is connected to the pulley groove 1a4 through a pulley group 1d1.

[0038] Specifically, in order to solve the technical problem of heat dissipation of the heat dissipation pipe 1a, the present invention dissipates heat and transports the engine oil by configuring the corrugated outer tube 1a2 to be a specific corrugated structure similar to a bellows, thereby increasing the contact area between the engine oil and the heat dissipation pipe 1a, that is, the corrugated outer tube 1a2, and then utilizes the drive motor 1d and the pulley group 1d1 to drive the corrugated outer tube to rotate, so that the corrugated outer tube 1a2 contacts and rubs with the outer water-absorbing sponge group 1c, and the water-absorbing sponge group 1c rubs water on the tube body of the corrugated outer tube 1a2, and then the side of the corrugated outer tube 1a2 coated with water rotates to face the heat dissipation fan 1e, and the heat dissipation fan 1e dries the water on the tube wall of the corrugated outer tube 1a2 to absorb heat, thereby further improving the heat dissipation efficiency of the heat dissipation pipe 1a.

[0039] like Figures 6 to 9 As shown, the following preferred technical solutions are provided:

[0040] The absorbent sponge group 1c is installed on the main frame 3 through the water supply box 1b. The absorbent sponge group 1c and the water supply box 1b are slidingly connected. The water supply box 1b is installed on the main frame 3 through the mounting rod 3a. The water supply box 1b can be connected to a vehicle-mounted water tank or a rainwater collection system.

[0041] Specifically, to solve the technical problem of continuously supplying water to the water-absorbing sponge group 1c, the present invention supplies water to the water-absorbing sponge group 1c through the water supply tank 1b. The water tank and the water-absorbing sponge group 1c are fixed on the main frame 3 by the installation rod 3a so that they are located directly above the corrugated outer pipe 1a2. A sliding connection is adopted between the water-absorbing sponge group 1c and the water supply tank 1b to facilitate the installation and replacement of the water-absorbing sponge group 1c. The cooperation of the slide bar 1c1 and the chute 1b3 is used to achieve the quick connection between the water-absorbing sponge group 1c and the water supply tank 1b. During installation, each sponge block of the water-absorbing sponge group 1c needs to be correspondingly clamped in the wave groove on the outside of the corrugated outer pipe 1a2 to ensure that each sponge block can wipe and coat it when the corrugated outer pipe 1a2 rotates.

[0042] A chute 1b3 is provided at the bottom of the water supply tank 1b. The chute 1b3 is slidably connected to the water-absorbing sponge group 1c through a slide bar 1c1. The slide bar 1c1 is arranged at the top of the water-absorbing sponge group 1c.

[0043] An inlet 1b1 that can communicate with the vehicle-mounted water tank or the rainwater collection system is provided at the top of the water supply tank 1b. A number of water seepage holes 1b2 are provided at the top of the water supply tank 1b. A water level sensor is installed in the water supply tank 1b.

[0044] Specifically, to solve the technical problems of water inlet and outlet of the water supply tank 1b, the present invention realizes the water supply to the water supply tank 1b by connecting the water supply tank 1b with the vehicle-mounted water tank or the rainwater collection system. The water level sensor in the water supply tank 1b is used to monitor the water level of the water supply tank 1b. When the water level in the water supply tank 1b is too low, the water in the vehicle-mounted water tank or the rainwater collection system enters the water supply tank 1b from the inlet 1b1. The water in the water supply tank 1b slowly seeps into the water-absorbing sponge group 1c through the water seepage holes 1b2 to keep the water-absorbing sponge group 1c moist.

[0045] As Figures 6 to 9 shown, the following preferred technical solutions are provided:

[0046] The pressure-holding component 2 is a screw conveyor 2a. One end of the conveying pipe 2a1 of the screw conveyor 2a is movably installed in the inner pipe 1a1 and is butted against the pipe orifice of the inner pipe 1a1, and the other end is fixedly connected to the pipe rack 3b. One end of the screw conveyor roller 2a2 of the screw conveyor 2a passes through the conveying pipe 2a1 and extends into the corrugated outer pipe 1a2 and is movably connected to the pipe orifice of the pipe head 1a3. The discharge port of the conveying pipe 2a1 is communicated with the oil circuit of the turbocharger.

[0047] Specifically, to solve the technical problem of the stable oil supply of the turbocharger, the present invention forms a spiral oil delivery structure through the spiral delivery roller 2a2, the delivery pipe 2a1 and the heat dissipation pipe 1a. The spiral delivery roller 2a2 is used to deliver the oil in the corrugated outer pipe 1a2 to the turbocharger through the delivery pipe 2a1, maintaining the stable oil supply and pressure of the turbocharger, and effectively preventing the turbocharger from operating without oil and oil return. When the corrugated outer pipe 1a2 and the inner pipe 1a1 rotate, since the delivery pipe 2a1 is movably connected to the inner pipe 1a1 and fixedly connected to the pipe support 3b, the delivery pipe 2a1 will not rotate at this time. And since the spiral delivery roller 2a2 is also movably connected to the pipe orifice of the pipe head 1a3, it can ensure that the operation of the spiral delivery roller 2a2 is not affected by the rotation of the corrugated outer pipe 1a2.

[0048] A wind guide box 2c is installed outside the connection between the delivery pipe 2a1 and the oil circuit of the turbocharger. The wind guide box 2c is installed on the main frame 3 through the fan base 2b1. The wind guide box 2c blows air to dissipate heat at the connection between the delivery pipe 2a1 and the oil circuit of the turbocharger through the blower 2b. The air blowing frame is installed on the fan frame, and the fan frame is movably installed on the side of the main frame 3 away from the drive motor 1d.

[0049] The wind guide box 2c is communicated with the air blowing port 2c1 of the blower 2b. A plurality of air outlet ports 2c2 are opened on the wind guide box 2c. Each air outlet port 2c2 is directly opposite to the connection between the delivery pipe 2a1 and the oil circuit of the turbocharger. A wind dispersing plate 2c3 is installed at each air outlet port 2c2.

[0050] Specifically, to further improve the heat dissipation efficiency of the oil, the present invention blows air to the connection between the delivery pipe 2a1 and the oil circuit of the turbocharger through the blower 2b and the wind guide box 2c, and uses the wind dispersing plate 2c3 to disperse the wind to the periphery of the delivery pipe 2a1 and the oil pipeline of the turbocharger.

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
