Description

Technical Field

[0001] This utility model relates to the technical field of locomotive thermal management systems, and in particular to a modular mechanical room thermal management system. Background Technology

[0002] In the rail transit sector, locomotives typically house high-heat-density equipment such as transformers, converters, and compressors within their mechanical compartments. The continuous operation of these devices generates a significant amount of heat; if this heat cannot be dissipated promptly, it can lead to overheating, performance degradation, or even damage. Existing thermal management systems often suffer from the following problems: First, inefficient airflow organization can easily lead to thermal short circuits or localized overheating; second, high system integration makes maintenance and repair difficult, and a single component failure can cause the entire system to shut down, thus affecting heat dissipation within the mechanical compartment. Utility Model Content

[0003] The main purpose of this utility model is to provide a modular mechanical room thermal management system, which aims to solve the technical problem that the existing locomotive cooling system has unreasonable airflow organization, which easily leads to thermal short circuits or local overheating.

[0004] To achieve the above objectives, this utility model proposes a modular mechanical room thermal management system, comprising a detachable upper cabinet and a lower cabinet. An auxiliary variable fan is installed in the lower cabinet, and the lower cabinet is provided with a first air inlet and a first air outlet. The upper cabinet includes an evaporation chamber and a condensation chamber, with the condensation chamber located above the evaporation chamber. An evaporation fan is installed in the evaporation chamber, and a compressor and a condenser fan are installed in the condensation chamber. The evaporation chamber is provided with a second air inlet, and the condensation chamber is provided with a second air outlet, a third air inlet, and a third air outlet.

[0005] The modular mechanical room thermal management system of this utility model is further improved in that the third air inlet is located on the side of the condensation chamber and the third air outlet is located on the top surface of the condensation chamber.

[0006] The modular mechanical room thermal management system of this utility model is further improved in that the second air outlet is located on the side of the condensation chamber, and the evaporator fan is connected to the second air outlet by an air duct.

[0007] The modular mechanical room thermal management system of this utility model is further improved in that an auxiliary transformer is installed in the lower cabinet, and the air inlet of the auxiliary transformer fan is directly opposite the auxiliary transformer.

[0008] The modular mechanical room thermal management system of this utility model is further improved in that the number of the evaporator fan, the compressor and the condenser fan are all at least two sets.

[0009] The modular mechanical room thermal management system of this utility model is further improved in that the condenser fan is installed on the top of the evaporation chamber through an anti-detachment component. The anti-detachment component includes a hanging plate and a self-locking indexing pin. The top of the evaporation chamber is provided with a sliding groove for the hanging plate to be slidably installed, and the hanging plate is provided with a slot that matches the self-locking indexing pin.

[0010] The modular mechanical room thermal management system of this utility model is further improved in that the compressor is installed at the bottom of the condensing chamber by means of a mounting bracket, and the mounting bracket is provided with a clamp for clamping the compressor.

[0011] The modular mechanical room thermal management system of this utility model is further improved in that a first shock-absorbing pad is provided between the compressor and the inner wall of the condensing chamber, and a second shock-absorbing pad is provided between the compressor and the clamp.

[0012] The modular mechanical room thermal management system of this utility model is further improved in that the first shock-absorbing pad and the second shock-absorbing pad are both made of rubber.

[0013] In addition, this utility model also provides a heat exchange method using the modular mechanical room heat management system described above, comprising the following steps: Hot air enters through the first air inlet, is cooled by the auxiliary blower, and then exits through the first air outlet. Hot air enters through the second air inlet, is cooled by the evaporator fan, and then exits through the second air outlet. Cold air enters through the third air inlet, is heated by the compressor and condenser fan, and then exits through the third air outlet.

[0014] The technical solution of this utility model has the following beneficial effects: This utility model's modular mechanical room thermal management system adopts a side-intake and top-outtake airflow organization, which follows the natural law of hot air rising, reduces fan energy consumption, achieves strict separation of hot and cold air, improves heat dissipation efficiency, and forms an efficient and smooth heat dissipation path. It avoids the mutual mixing and interference of hot and cold airflows, thus achieving efficient heat exchange. This solves the technical problem of existing locomotive cooling systems having unreasonable airflow organization, easily leading to thermal short circuits or localized overheating. This utility model designs the upper and lower cabinets as detachable structures, further dividing the upper cabinet into an evaporation chamber and a condensation chamber, ensuring they do not interfere with each other and facilitating independent maintenance or disassembly. The condensation chamber is equipped with dual fans and dual compressors, while the evaporation chamber is equipped with dual ventilators, forming a redundant heat dissipation system. This achieves efficient heat dissipation, convenient maintenance, and stable operation, making it particularly suitable for mechanical room environments with limited space and high heat dissipation requirements.

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.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0022] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.

[0023] like Figures 1-2 As shown, this utility model proposes a modular mechanical room thermal management system, including a detachable upper cabinet 7 and a lower cabinet 8. The lower cabinet 8 houses an auxiliary variable fan 6 and has a first air inlet and a first air outlet. The upper cabinet 7 includes an evaporation chamber 9 and a condensation chamber 11, with the condensation chamber 11 located above the evaporation chamber 9. The evaporation chamber 9 houses an evaporator fan 1, and the condensation chamber 11 houses a compressor 2 and a condenser fan 5. The evaporation chamber 9 has a second air inlet 16, and the condensation chamber 11 has a second air outlet 17, a third air inlet 18, and a third air outlet 19. The upper cabinet 7 and lower cabinet 8 are detachable via a screw connection, allowing for individual disassembly without affecting each other. A partition 10 is provided between the evaporation chamber 9 and the condensation chamber 11 to reduce mutual interference between the gases in the two chambers. The side-inlet and top-outlet airflow path of this utility model is scientifically and rationally designed, avoiding airflow turbulence and hot-cold mixing, resulting in high heat dissipation efficiency. Key heat dissipation components (fan and compressor 2) adopt a dual redundancy design, so a single point of failure will not affect the basic operation of the system. The upper and lower cabinets 8 and internal components are modularly designed, supporting individual disassembly and maintenance, which significantly reduces maintenance time and difficulty. The anti-detachment structure ensures the installation reliability of moving parts, and the shock-absorbing pads effectively suppress vibration and noise, improving the overall stability and environmental friendliness of the system.

[0024] The modular mechanical room thermal management system of this utility model is further improved in that the third air inlet 18 is located on the side of the condenser chamber 11, and the third air outlet 19 is located on the top surface of the condenser chamber 11. This side-inlet and top-outlet airflow organization follows the natural law of hot air rising, reduces fan energy consumption, achieves strict separation of hot and cold air, and improves heat dissipation efficiency. The condenser fan 5 and the third air outlet 19 are located at the top of the upper cabinet 7, allowing maintenance personnel to perform inspections and maintenance without obstructing the main airflow path. The concentrated exhaust of hot air from the top also makes it easier to detect the overall heat dissipation status and overheating faults by scanning from the top with equipment such as infrared thermal imagers. This structure ensures a very smooth airflow path, eliminating the need for complex ductwork inside the cabinet, saving internal space, and making the equipment layout more compact and neat.

[0025] The modular mechanical room thermal management system of this utility model is further improved in that the second air outlet 17 is located on the side of the condensation chamber 11, and the air duct 20 connecting the evaporator fan 1 and the second air outlet 17 is designed to separate the air inlet and outlet, thereby avoiding airflow turbulence.

[0026] The modular mechanical room thermal management system of this utility model is further improved in that an auxiliary transformer 12 is installed in the lower cabinet 8, and the air inlet of the auxiliary transformer fan 6 is directly opposite the auxiliary transformer 12. By equipping the auxiliary transformer 12 with an independent auxiliary transformer fan 6, it can be ensured that the heat generated by the transformer can be discharged in a timely manner without interfering with the upper thermal management circulation system.

[0027] The modular mechanical room heat management system of this utility model is further improved in that the number of evaporator fan 1, compressor 2 and condenser fan 5 are all at least two sets. The setting of two sets of equipment enhances heat exchange efficiency and reliability, and can form a redundant heat dissipation system. When one system fails or is under maintenance, the other system can still maintain basic heat dissipation function, which greatly improves the availability of the system.

[0028] The modular mechanical room thermal management system of this utility model is further improved in that, for example Figures 3-4As shown, the condenser fan 5 is installed on the top of the evaporation chamber 9 via an anti-detachment assembly. This anti-detachment assembly includes a mounting plate 13 and a self-locking indexing pin 14. The top of the evaporation chamber 9 has a sliding groove for the mounting plate 13 to slide on. The structure of the self-locking indexing pin 14 is as described in patent CN217603101U. The mounting plate 13 has a slot that engages with the self-locking indexing pin 14. During installation, the condenser fan 5 is fixed to the mounting plate 13, and the mounting plate 13 is pushed into the sliding groove. When pushed to the end of the groove, the self-locking indexing pin 14, which has its own threads, is threaded and inserted into a welded nut on the mounting plate, creating a 5mm protrusion at the top. This 5mm protrusion forms the anti-detachment structure for the fan. When the fan needs to be removed, the fixing bolts are removed, and the fan falls from the top into the slot of the mounting plate 13. Pulling out the tail of the self-locking indexing pin 14 causes the protrusion to retract into the structure, releasing the lock. The condenser fan 5 can then be easily pulled out from the sliding groove along the mounting plate 13. The anti-detachment structure not only saves manpower during assembly, but also allows operators to push the condenser fan 5 and the mounting plate 13 to the installation position via the slide, eliminating the need for other auxiliary tools and personnel. This greatly saves time during missed assembly and maintenance in the machine room, and ensures that the fan will not loosen due to vibration during and after installation, thus greatly improving safety.

[0029] A further improvement of the modular mechanical room thermal management system of this utility model is that the compressor 2 is mounted on the bottom of the condensing chamber 11 via a mounting bracket 3, and the mounting bracket 3 is provided with a clamp 4 for securing the compressor 2. The compressor 2 is fixed by the mounting bracket 3 and the clamp 4 to prevent the compressor 2 from vibrating and shifting.

[0030] The modular mechanical room thermal management system of this utility model is further improved in that a first shock-absorbing pad 15 is provided between the compressor 2 and the inner wall of the condensing chamber 11, and a second shock-absorbing pad is provided between the compressor 2 and the clamp 4. The second shock-absorbing pad and the first shock-absorbing pad 15 can effectively absorb vibrations in the vertical and horizontal directions, thereby reducing the noise level of the entire system and extending the service life of the equipment.

[0031] The modular mechanical room thermal management system of this utility model is further improved in that the first shock-absorbing pad 15 and the second shock-absorbing pad are both made of rubber, which has a long service life, thereby reducing the number of maintenance and replacements.

[0032] In addition, this utility model also provides a heat exchange method using the modular mechanical room heat management system described above, comprising the following steps: Hot air enters through the first air inlet, is cooled by the auxiliary variable fan 6, and then is discharged through the first air outlet. Hot air enters through the second air inlet 16, is cooled by the evaporator fan 1, and is then discharged through the second air outlet 17. Cold air enters through the third air inlet 18, is heated by the compressor 2 and the condenser fan 5, and is then discharged through the third air outlet 19.

[0033] This utility model's modular mechanical room thermal management system adopts a side-intake and top-outtake airflow organization, which follows the natural law of hot air rising, reduces fan energy consumption, achieves strict separation of hot and cold air, improves heat dissipation efficiency, and forms an efficient and smooth heat dissipation path. It avoids the mutual mixing and interference of hot and cold airflows, thus achieving efficient heat exchange. This solves the technical problem of existing locomotive cooling systems having unreasonable airflow organization, which easily leads to thermal short circuits or localized overheating. This utility model designs the upper cabinet 7 and lower cabinet 8 as detachable structures. The upper cabinet 7 is further divided into an evaporator chamber 9 and a condenser chamber 11, ensuring they do not interfere with each other and are easy to maintain or disassemble independently. The condenser chamber 11 is equipped with dual fans and dual compressors 2, and the evaporator chamber 9 is equipped with dual ventilators, forming a redundant heat dissipation system. This achieves efficient heat dissipation, convenient maintenance, and stable operation, making it particularly suitable for mechanical room environments with limited space and high heat dissipation requirements.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
