Description

A cooling device for the middle corridor of a diesel locomotive Technical Field

[0001] The invention belongs to the technical field of diesel locomotives, and in particular relates to a cooling device for a middle corridor of a diesel locomotive. Background Art

[0002] Currently, diesel locomotives typically feature a two-corridor design, with the cooling system located in the middle of the two corridors. Cooling air enters through the side walls and passes through the corridors on both sides before entering the cooling system. The high air volume used by the cooling system not only creates a high negative pressure in the cooling chamber, but also draws large amounts of rainwater and windblown sand into the cooling chamber, compromising the safe operation of other electrical equipment below the cooling system. Furthermore, windblown sand and rainwater easily accumulate on the corridor floor, compromising interior hygiene and creating a slipping hazard for drivers and passengers during inspections.

[0003] Summary of the Invention

[0004] In order to solve the above problems existing in the prior art, the object of the present invention is to provide a cooling device for the middle corridor of a diesel locomotive with an independent air duct.

[0005] The technical solution adopted in the present invention is:

[0007] The radiator module of the present invention is mounted upright on the locomotive side wall, while the fan module is mounted on the roof. A sealing module is connected between the fan and radiator modules to form an independent air duct. This prevents air from passing through the interior of the locomotive cooling compartment, preventing rainwater and windblown sand from entering the cooling compartment, providing effective rain and sand protection. Furthermore, the fan module is mounted on the locomotive roof, eliminating the need for corridor space and facilitating the passage and inspection of drivers and passengers.

[0009] As a preferred embodiment of the present invention, the radiator mounting frame is welded to the locomotive side wall, and the top of the radiator is pressed against the locomotive inner wall. The radiator bottom adopts a seat plate mounting structure, and the top adopts a pressing mounting structure. This simplifies the sealing of the front and rear air ducts of the radiator and makes the radiator easy to install and disassemble.

[0010] As a preferred solution of the present invention, the radiator is provided with a lifting lug.

[0011] As a preferred solution of the present invention, a side wall air inlet net is connected between the radiator mounting frame and the top of the radiator, the side wall of the locomotive is provided with an air inlet window, and the side wall air inlet net is arranged in the air inlet window of the side wall of the locomotive.

This platform effectively conceals the fan motor mounting base and mounting bolts, ensuring smooth airflow and effectively reducing air resistance. This avoids the vortexes and turbulence that can easily increase air resistance associated with conventional motor mounting bases.

[0014] As a preferred solution of the present invention, a sealing and pressing device is connected to the fan motor mounting bracket, and the sealing and pressing device is pressed against the side wall of the locomotive.

[0015] As a preferred solution of the present invention, a fan protection net is connected to the fan motor mounting bracket, and the fan protection net is located on the air outlet side of the cooling fan.

[0016] As a preferred solution of the present invention, the sealing module includes an air duct sealing plate, and air duct beams are connected on both sides of the air duct sealing plate, wherein the air duct beam on one side is connected to the radiator module, and the air duct beam on the other side is connected to the fan module; an opening is provided on the air duct sealing plate, and an inspection door assembly is connected to the opening of the air duct sealing plate.

The door frame assembly is connected to a door panel via a tightening bolt, and sealing strips are provided on the door frame component and the door panel.

[0018] The access door assembly utilizes a "well"-shaped arc structure, which not only allows for modular design and production, but also features a door frame that serves as a structural beam for the sealing module, significantly reducing weight.

[0019] The beneficial effects of the present invention are:

[0020] The radiator module of the present invention is mounted upright on the locomotive side wall, while the fan module is mounted on the roof.

DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features therein may be combined with each other unless there is a conflict.

[0033] As shown in Figure 1, the diesel locomotive intermediate corridor cooling device of this embodiment is divided into three functional modules: a radiator module 1, a fan module 2, and a sealing module 3. These three modules form an independently ventilated intermediate corridor cooling device. Removing the fan motor 22 mounting module and the sealing device allows for the installation and maintenance of other equipment within the vehicle. The radiator module 1 is mounted on the side wall of the locomotive 4, with the air inlet side of the radiator module 1 communicating with the exterior of the locomotive 4. The fan module 2 is mounted on the top of the locomotive 4, with the air outlet side of the fan module 2 communicating with the exterior of the locomotive 4. The sealing module 3 is connected between the fan module 2 and the radiator module 1, forming a sealed passage between the sealing module 3 and the inner wall of the locomotive 4.

[0034] The radiator module 1 of the present invention is mounted upright on the side wall of the locomotive 4, and the fan module 2 is mounted on the roof. A sealing module 3 is connected between the fan module 2 and the radiator module 1 to form an independent air duct. The air flows through: outside air, side wall air inlet mesh 14, radiator 12, sealed air duct, cooling fan 23, and roof. The air used by the cooling device no longer passes through the interior of the cooling chamber of the locomotive 4, preventing rainwater and wind and sand from entering the cooling chamber, and having a good rain and wind protection effect. In addition, the fan module 2 is installed on the top of the locomotive 4 to avoid occupying the corridor, which can facilitate the passage and inspection of drivers and passengers.

[0035] Specifically, as shown in Figure 2, the radiator module 1 includes a radiator mounting frame 11, which is connected to the side wall of the locomotive 4. A radiator 12 is installed on the radiator mounting frame 11, and the top of the radiator 12 is connected to the inner wall of the locomotive 4. One end of the sealing module 3 is connected to the radiator mounting frame 11.

[0036] The radiator mounting frame 11 is welded to the locomotive 4, increasing the vehicle's strength and preventing rainwater and windblown sand from seeping into the cooling chamber. The radiator 12 features a baseplate mounting structure at the bottom and a compression mounting structure at the top. The radiator 12 is mounted upright, with a lower mounting seat and an upper mounting seat. The lower mounting seat connects to the radiator mounting frame 11, while the upper mounting seat is compressed against the inner wall of the locomotive 4. This simplifies the sealing of the front and rear air ducts of the radiator 12, making it easy to assemble and disassemble. Lifting lugs 13 are also provided on the radiator 12.

[0037] A side wall air inlet net 14 is connected between the radiator mounting frame 11 and the top of the radiator 12 . An air inlet window is provided on the side wall of the locomotive 4 . The side wall air inlet net 14 is provided in the air inlet window on the side wall of the locomotive 4 .

[0038] Specifically, as shown in Figure 3, the fan module 2 includes a fan motor mounting bracket 21 connected to the top of the locomotive 4. A fan motor 22 is mounted on the fan motor mounting bracket 21. The output end of the fan motor 22 is connected to a cooling fan 23. The air outlet of the cooling fan 23 communicates with the outside of the locomotive 4. One end of the sealing module 3 is connected to the fan motor mounting bracket 21. A fan protection net 26 is connected to the fan motor mounting bracket 21 and is located on the air outlet side of the cooling fan 23.

[0039] The fan module 2 utilizes a removable mounting structure. The fan motor mounting bracket 21 is sealed to the sidewalls and radiator module 1 using sealing strips. A sealing and compression device 25 is also installed at the sidewall seal to ensure effective sealing. The fan motor 22 utilizes a chassis mounting structure, which reduces weight while also serving as a framework for the removable sealing device.

[0040] As shown in Figure 4 , the fan motor mounting bracket 21 is provided with a cylindrical support platform 24, within which the fan motor 22 is mounted. Cylindrical support platform 24 has ventilation openings for cooling the fan motor 22. Cylindrical support platform 24 effectively conceals the fan motor 22 mounting structure and mounting bolts, ensuring smooth airflow and effectively reducing air resistance. This avoids the issues associated with conventional motor mounting brackets that can easily generate vortices and turbulence, which increase air resistance.

[0041] The cylindrical support platform 24 comprises two cylinders with a reinforcing rib between them. The inner cylinder of the cylindrical support platform 24 features a vent for motor cooling. The outer cylinder of the cylindrical support platform 24 features a semicircular hole for mounting bolts. This double-cylinder boss structure effectively conceals the fan motor 22's mounting base structure and mounting bolts, ensuring smooth airflow and effectively reducing air resistance. This avoids the vortexes and turbulence that can easily increase air resistance associated with conventional motor mounting bases.

[0042] Specifically, as shown in Figure 5, the sealing module 3 includes an air duct sealing plate 31, with air duct beams 32 connected to both sides of the air duct sealing plate 31. The air duct beam 32 on one side is connected to the radiator module 1, and the air duct beam 32 on the other side is connected to the fan module 2. The air duct sealing plate 31 is provided with an opening, and the opening of the air duct sealing plate 31 is connected to the access door assembly 33. The air duct sealing plate 31 connects the radiator module 1 and the fan module 2 to form an air duct. The air duct sealing plate 33 adopts a circular plate structure, which improves airflow and effectively reduces air resistance in the flow channel.

[0043] Specifically, as shown in Figures 6 and 7, the inspection door assembly 33 includes a door frame assembly 331, which is connected to the opening of the air duct sealing plate 31. The door panel 332 is connected to the door frame assembly 331 by a tightening bolt. Sealing strips 333 are provided on the side of the door frame assembly 331 facing the door panel 332 and on the side of the door panel 332 facing the door frame assembly 331, and the two sealing strips 333 are staggered.

[0044] As shown in Figure 7, an opening is provided in door frame assembly 331. The area of ​​door panel 332 is larger than that of door frame assembly 331, and door panel 332 completely covers door frame assembly 331. A sealing strip 333 on door frame assembly 331 is provided on the inner edge of the opening of door frame assembly 331. A sealing strip 333 on door panel 332 is provided on the outer edge of door panel 332. Both the sealing strip 333 on door frame assembly 331 and the sealing strip 333 on door panel 332 are compressed between door frame assembly 331 and door panel 332, and the two sealing strips 333 are staggered, forming a double-strip sealing structure.

[0045] The inspection door assembly 33 utilizes a "well"-shaped arc structure, which not only allows for modular design and production, but also allows the door frame component 331 to serve as the structural beam for the sealing module 3, resulting in a significant weight reduction. The inspection door assembly 33 utilizes a double-strip sealing structure, which significantly reduces the recessed space in the door panel 332, ensuring unobstructed air flow and reducing air resistance, which is beneficial for the cooling performance of the cooling device. The double-strip sealing structure also facilitates the effective sealing of the arc-shaped door panel 332 under negative pressure conditions, ensuring unobstructed drainage from the inside, preventing rainwater from accumulating, and providing a superior rainproof effect. The door panel 332 is constructed of lightweight materials, allowing for quick assembly and disassembly, and facilitating the purge and maintenance of the radiator 12.

[0046] The fan module 2 of the present invention will not block the middle corridor of the cooling room of the diesel locomotive 4. The corridor height is not less than 1900 mm, and the narrowest part of the top is greater than 600 mm, which can facilitate the passage of drivers and passengers and equipment inspection.

[0047] The present invention realizes independent ventilation of the cooling device 4 of the diesel locomotive, and the air used by the cooling device no longer passes through the interior of the cooling chamber, thereby preventing rainwater and wind and sand from entering the cooling chamber, and having a good rain and wind protection effect.

[0048] The radiator 12 is installed independently, which makes it easy to disassemble and inspect the cooling fan 23 and the motor without disassembling the radiator 12 and draining the coolant.

[0049] The fan motor 22 module adopts a movable installation structure to facilitate the lifting and maintenance of the equipment in the vehicle.

[0050] The cylindrical support platform 24 for mounting the fan motor 22 adopts a double-cylindrical boss structure, which has a simple structure, good flow field smoothness, and effectively reduces air resistance.

[0051] The sealing module 3 adopts a movable installation structure, which is quick to disassemble and assemble, and convenient for purging and maintaining the radiator 12.

[0052] Installation process:

[0053] The radiator mounting frame 11 is welded to the side wall and partition wall of the vehicle body. The radiator 12 is vertically hoisted from the roof and placed on the radiator mounting frame 11. It is fastened and installed with bolts through the bottom seat plate and the top mounting seat of the radiator 12. The radiator 12 is easy to disassemble and assemble.

[0054] The cooling fan 23, fan motor 22, and fan protection screen 26 are assembled under the vehicle with the fan motor mounting bracket 21 and hoisted to the roof. Sealing strips 33 are used to seal the fan motor 23 against the side walls and radiator module 1. Bolts are also installed at the side wall seals to ensure an effective seal. The fan motor 22 is mounted on a chassis, which reduces weight and also serves as the mounting frame for the movable sealing device.

[0055] After installing the radiator module 1 and fan module 2, a movable curved beam 31 is installed between the two modules. Sealing strips 33 are placed around the movable curved beam 31. Then, a sealing plate 32 is installed to connect the radiator module 1 and fan module 2 to form an independent air duct. The sealing device is made of lightweight materials and is quick to disassemble and assemble, facilitating purge and maintenance of the radiator 12.

[0056] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
