Description

Technical Field

[0001] This invention relates to the field of automotive technology, and more particularly to an automotive ATS cooling fan. Background Technology

[0002] ATS stands for Automatic Train Supervision, and traditional buses use ATS cooling systems. However, due to limited chassis space, most ATS cooling systems are installed in semi-enclosed compartments. Furthermore, because the ATS fans use an intake method, only the cooling fins and heat pipes are exposed, while the cooling fans are concealed inside the compartment. Over long periods of operation, dust accumulates on the back of the ATS fan blades and inside the ATS fan motor.

[0003] Conventional ATS systems cannot self-diagnose dust accumulation or perform self-cleaning, resulting in delayed dust removal. In most buses, the ATS fan space is enclosed, making it difficult to assess the dust accumulation inside the system and on the fan itself. Dust accumulation is often judged based on driver experience, vehicle coolant temperature, and unusual noises or vibrations from the ATS. By the time these phenomena occur, the ATS is already severely dusty, causing irreversible damage to its stability and lifespan. The enclosed fan space in most buses makes dust removal extremely difficult, and thorough cleaning is virtually impossible without disassembling the ATS system. Over time, dust accumulation severely degrades the dynamic balance accuracy of the ATS fan, leading to decreased fan speed, unusual fan noises, and blade vibrations. This directly reduces the ATS system's lifespan, and in severe cases, can cause the fan to burn out, the cooling system to fail, and indirectly affect the stability and lifespan of the powertrain. Summary of the Invention

[0004] The purpose of this invention is to provide an automotive ATS cooling fan to solve the technical problem of unpredictable dust accumulation on the ATS cooling fan, which leads to a decrease in the service life of the ATS system.

[0005] To achieve the above objectives, the specific technical solution of the present invention for an automotive ATS cooling fan is as follows:

[0006] An automotive ATS cooling fan includes a housing and a fan assembly disposed within the housing. The housing has an air inlet and an air outlet on opposite side walls. The fan assembly is fixed inside the housing at the air outlet. An ATS controller is disposed on the housing. A dust removal device is disposed between the fan assembly and the air inlet. The fan assembly and the dust removal device are electrically connected to the ATS controller.

[0007] Furthermore, the dust removal device includes at least two dust removal pipes, one end of each dust removal pipe is connected, the free end of the dust removal pipe extends away from the rotation axis of the fan assembly, and the wall of the dust removal pipe facing the fan assembly is provided with multiple air outlets, and gas is introduced into the dust removal pipe to blow the fan assembly.

[0008] Furthermore, the dust removal device includes 3-6 dust removal pipes, each dust removal pipe is evenly distributed around the fan assembly's rotation axis, the dust removal pipes are arc-shaped, and the free end of the dust removal pipe is close to the fan assembly.

[0009] Furthermore, each dust removal pipe is connected to a main pipe at its connecting end. The air inlet end of the main pipe is connected to the air inlet pipe, which is connected to the air storage tank. A pressure limiting valve and a three-way valve are connected to the air inlet pipe respectively. The three-way valve is electrically connected to the ATS controller. The opening and closing of the three-way valve is controlled to control the opening state of the dust removal device.

[0010] Furthermore, the dust removal device also includes a dust removal motor, which includes a motor housing and an air passage chamber inside the motor housing. The main rotating pipe passes through the motor housing and communicates with the air passage chamber.

[0011] Furthermore, the dust removal motor is a DC stepper motor. The outer wall of the main pipe end is equipped with a self-locking component. A partition is provided inside the motor housing.

[0025] To better understand the purpose, structure, and function of this invention, a vehicle ATS cooling fan of this invention will be described in further detail below with reference to the accompanying drawings.

[0026] like Figures 1-2As shown, the automotive ATS cooling fan of the present invention includes a housing 1 and a fan assembly 2 disposed inside the housing 1. The opposite side walls of the housing 1 are respectively provided with an air inlet and an air outlet. The fan assembly 2 is fixed inside the housing 1 at the air outlet. An ATS controller 3 is provided on the housing 1. A dust removal device 6 is provided between the fan assembly 2 and the air inlet for removing dust from the fan assembly 2. The fan assembly 2 and the dust removal device 6 are electrically connected to the ATS controller 3. The ATS controller 3 determines the amount of dust accumulation on the fan assembly 2 according to the operating parameters of the fan assembly 2, and activates the dust removal device 6 to remove dust from the fan assembly 2.

[0027] like Figure 2 As shown, the outer casing 1 includes a bottom shell 11 and a cover 12 fixed on the bottom shell 11. The bottom shell 11 is provided with an air inlet and is rectangular. The cover 12 is generally truncated cone-shaped. The inner cavity of the truncated cone-shaped cover 12 accommodates the fan assembly 2. The cover 12 away from the bottom shell 11 is provided with a circular air outlet. Mounting holes are provided on the cover 12 at the air outlet and on the fan assembly 2 respectively. The fan assembly 2 is fixed to the outer wall of the cover 12 by bolts.

[0028] Dust is removed from fan assembly 2 using high-pressure gas, such as... Figures 3-5 As shown, the dust removal device 6 includes at least two dust removal pipes 63, with one end of each dust removal pipe 63 connected. The free end of the dust removal pipe 63 extends away from the rotation axis of the fan assembly 2. The wall of the dust removal pipe 63 facing the fan assembly 2 is provided with multiple air outlets 631. Gas is introduced into the dust removal pipe 63 to blow the fan assembly 2, thereby achieving the purpose of dust removal.

[0029] Preferably, the dust removal device 6 includes 3-6 dust removal pipes 63, each dust removal pipe 63 is evenly distributed circumferentially around the rotation axis of the fan assembly 2, the dust removal pipe 63 is an arc-shaped pipe, the free end of the dust removal pipe 63 is close to the fan assembly 2, the arc-shaped dust removal pipe 63 effectively utilizes the principle of aerodynamics to improve the dust removal efficiency of a unit of compressed air.

[0030] Each dust removal pipe 63 is connected to a main pipe 62 at its connecting end. The air inlet end of the main pipe 62 is connected to an air inlet pipe 64, which is connected to an air storage tank 65.

[0031] A pressure limiting valve 66 and a three-way valve 67 are connected to the air intake pipe 64 respectively. The three-way valve 67 is electrically connected to the ATS controller 3. The opening and closing of the three-way valve 67 is controlled to control the opening state of the dust removal device 6.

[0032] To further improve the dust removal effect of the dust removal device 6, the dust removal pipe 63 is rotated to scan the fan assembly 2, thereby expanding the radiation area of ​​the dust removal pipe 63. Simultaneously, a smaller number of dust removal pipes 63 can be arranged to prevent the dust removal device 6 from obstructing the airflow into the fan assembly 2. The dust removal device 6 also includes a dust removal motor 61, such as... Figure 6 As shown, the dust removal motor 61 includes a motor housing 611, an air passage chamber is provided inside the motor housing 611, the main pipe 62 rotates through the motor housing 611 and communicates with the air passage chamber, the air inlet pipe 64 passes through the side wall of the motor housing 611 and communicates with the air passage chamber, and the dust removal motor 61 is electrically connected to the ATS controller 3.

[0033] The dust collector motor 61 is a DC stepper motor. A self-locking assembly 621 is provided on the outer wall of the main pipe 62. A partition 612 is provided inside the motor housing 611, dividing the cavity within the motor housing 611 into an air passage chamber and a self-locking chamber. The self-locking assembly 621 is placed inside the self-locking chamber, and the end of the main pipe 62 extends into the air passage chamber. A sealed bearing is provided between the outer wall of the main pipe 62, the partition 612, and the motor housing 611. When not in operation, the main pipe 62 is locked by the self-locking assembly 621 of the dust collector motor 61, ensuring that the main pipe 62 is fixed and does not affect the normal operation of the fan assembly 2. During dust collection, the dust collector motor 61 and the solenoid valve are directly controlled by the ATS controller 3, and the fan assembly 2 is locked by a mechanical structure to ensure that it does not rotate.

[0034] The dust removal motor 61 is fixed on the bracket 5, which is fixed on the inner wall of the cover 12 at the air outlet. The bracket 5 includes a connecting ring 51 with a fixing hole that matches the mounting hole. The fan assembly and the bracket 5 are fixed to the outer and inner walls of the cover 12 respectively by bolts.

[0035] The bracket 5 also includes multiple L-shaped support rods 52 fixed to the connecting ring 51. The ends of each support rod 52 are fixed to the positioning ring 53. The dust removal motor 61 is fixed inside the positioning ring 53. The connecting ring 51 and the positioning ring 53 are coaxially arranged.

[0036] A water pump 8 is installed on the outer shell 1 below the cover 12. The inlet of the water pump 8 is connected to an inlet pipe. A cooling pipe is installed on the bottom shell 11. The outlet of the cooling pipe is located at the bottom of the bottom shell 11 and is connected to the inlet pipe. The outlet of the water pump 8 is connected to an outlet pipe. A temperature sensor is installed on the outlet pipe. The temperature sensor is electrically connected to the ATS controller 3 to reduce the difficulty and space required for the arrangement of the cooling water pipe and increase the air intake and heat dissipation effect.

[0037] The operating parameters of the fan assembly 2 include the current value of the motor of the fan assembly 2 and the speed of the fan. In addition, the water outlet temperature value of the water pump 8 detected by the temperature sensor, the noise value detected by the noise sensor 4, and the acceleration value detected by the acceleration sensor 7 can be obtained through the ATS controller 3. If the above detected values ​​are greater than the threshold, it is determined that the fan assembly 2 needs to be dusted. The ATS controller 3 opens the solenoid valve and the dust removal motor 61, and the compressed air in the air tank 65 is introduced into the dust removal pipe 63 and blown out compressed air to the fan assembly 2 to achieve the purpose of dust removal.

[0038] The ATS controller 3 is equipped with a noise sensor 4 for detecting the noise of the fan assembly 2, and the fan assembly 2 is equipped with an acceleration sensor 7. The noise sensor 4 and the acceleration sensor 7 are electrically connected to the ATS controller 3 respectively.

[0039] In the dust removal process of the dust removal device 6 for the fan assembly 2, there are two working modes. One is the pulse dust removal mode: the dust removal motor 61 first rotates 15°, the self-locking component 621 of the dust removal motor 61 locks, the solenoid valve connects the air source, and compressed air enters the main pipe 62 and the dust removal pipe 63 through the air passage. The air outlet removes dust from the fan assembly 2. After blowing up the dust for 2 seconds, the dust removal motor 61 rotates another 15°. The above steps are repeated until the dust removal rotor rotates 5 times, then the operation stops, and the horizontal speed dust removal mode is entered. In the pulse dust removal mode, the dust removal device uses gas impact to target the dust accumulated on the fan blades of the fan assembly 2, knocking off the stubborn dust.

[0040] The second mode is constant speed dust removal mode: the dust removal motor 61 rotates at a constant speed, such as 120 rpm. The solenoid valve connects the air source, and the main pipe 62 rotates at a constant speed to blow dust from the fan assembly 2. In this mode, the stubborn dust and fine dust adsorbed on the assembly will be quickly blown out of the ATS system and blown into the atmosphere through the back of the ATS. This mode will automatically stop after 5 minutes.

[0041] The ATS cooling fan used in this vehicle has a dust removal device 6 installed between the fan assembly 2 and the air inlet of the housing. This can effectively reduce the labor cost of dust removal in the later stage of the bus, ensure the long-term stable operation of the ATS system without human maintenance, and greatly increase the service life of the ATS system under various harsh road conditions.
