Description

Technical Field

[0001] This utility model relates to the field of railway locomotive heat exchanger technology, and in particular to a high-efficiency heat exchanger for railway locomotives. Background Technology

[0002] A heat exchanger is a device used to exchange heat between two or more fluids at different temperatures. During the operation of railway locomotives, key equipment such as diesel engines and traction converters generate a large amount of heat. If the heat is not dissipated in time, it will seriously affect the performance and service life of the equipment, and even threaten the safety of train operation. Therefore, heat exchangers are needed to treat the heat exchange and heat dissipation of railway locomotive equipment.

[0003] A search revealed that the document with publication number "CN222528399U" states that "this utility model discloses a high-efficiency heat exchanger, belonging to the field of heat exchanger technology; it includes a shell, a left box, a right box, a heat exchange tube, and two fixing plates; connecting plates are provided at both ends of the shell, the right end of the left box, and the left end of the right box; the shell, the left box, and the right box are fixed by bolts passing through the connecting plates; connecting plates are provided on both sides of the shell; two fixing plates are installed on the outside of the connecting plates; one end of the heat exchange tube is threaded to one fixing plate, and the other end is inserted into another fixing plate; by setting connecting plates connected by bolts, the shell, the left box, and the right box are easy to install and disassemble; by setting fixing plates installed on connecting plates by bolts, the fixing plates are easy to disassemble." In use, the heat exchange tube, with one end threaded to one fixing plate and the other end inserted into another fixing plate, is easy to disassemble, thus making the device easy to clean.

[0004] However, when faced with the complex vibration environment generated by locomotive operation, the fixed support structure of existing heat exchangers often cannot effectively reduce vibration, which makes the internal components of the heat exchanger prone to loosening and wear, affecting the service life and heat exchange efficiency of the heat exchanger.

[0005] Therefore, we provide a high-efficiency heat exchanger for railway locomotives to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a high-efficiency heat exchanger for railway locomotives, aiming to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-efficiency heat exchanger for railway locomotives includes a heat exchanger shell, a cold flow inlet at the right end of the heat exchanger shell, a cold flow tube inside the heat exchanger shell, a hot flow inlet at the bottom right side of the heat exchanger shell, a hot flow outlet at the top left side of the heat exchanger shell, a stabilizing component on the outside of the heat exchanger shell, the stabilizing component including a fixed bracket on the lower side of the heat exchanger shell, a supporting base installed on the inner side of the fixed bracket, a fixed ring frame movably connected to the upper side of the heat exchanger shell, a buffer support welded to the bottom end of the supporting base, and a fixed base plate welded to the bottom end of the buffer support.

[0009] As a further description of the above technical solution:

[0010] All the cold flow tubes are connected to the cold flow inlet, and the cold flow tubes are evenly distributed inside the heat exchanger shell.

[0011] As a further description of the above technical solution:

[0012] Baffles are installed between the cold flow pipes. The baffles have a 300° fan-shaped structure. There are five sets of baffles. The baffles are evenly distributed at equal distances. The notches of the baffles are arranged in a relative sequence.

[0013] As a further description of the above technical solution:

[0014] The fixed ring frame is provided with fixing bolts on both sides, and the fixing bolts are threadedly connected to the fixed bracket.

[0015] As a further description of the above technical solution:

[0016] A buffer pad is bonded to the inner wall of the fixed bracket and the inner wall of the fixed ring frame. The buffer pad is made of rubber.

[0017] As a further description of the above technical solution:

[0018] The buffer support column is equipped with a buffer spring inside, and the inner side of the buffer spring is equipped with a shock-absorbing damper. The shock-absorbing damper is welded to the buffer support column.

[0019] As a further description of the above technical solution:

[0020] A hydraulic support column is installed at the center of the fixed base plate. The hydraulic support column is attached to the bottom end of the support base frame. There are three sets of hydraulic support columns.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By setting up stabilizing components, the flow direction of heat flow can be guided by baffles during use, increasing the flow path of fluid within the heat exchanger shell, thereby improving the fullness and efficiency of heat exchange. At the same time, the entire structure is supported by buffer supports. When the locomotive is running, the vibration generated is first absorbed by the buffer supports, and then the buffer springs further mitigate the vibration energy. The shock absorption damping can effectively dissipate this energy and prevent vibration from being transmitted to the heat exchanger shell, thereby avoiding loosening and wear of internal components, extending the service life of the heat exchanger, and enhancing the stability of the heat exchanger in complex vibration environments.

[0023] 2. The buffer pads effectively reduce the impact and friction of the heat exchanger shell in a vibrating environment, protecting it from damage. They also reduce noise generation, improving the heat exchanger's durability and user comfort. The hydraulic support columns provide additional support for the heat exchanger, ensuring overall stability. Furthermore, the hydraulic support columns have a certain shock absorption function, further reducing the impact of vibration on the heat exchanger shell and ensuring its smooth operation.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Please see Figure 1-4 As shown, this utility model provides a technical solution: a high-efficiency heat exchanger for railway locomotives, including a heat exchanger shell 1, a cold flow inlet 2 at the right end of the heat exchanger shell 1, a cold flow pipe 3 inside the heat exchanger shell 1, a hot flow inlet 4 at the bottom right side of the heat exchanger shell 1, a hot flow outlet 5 at the top left side of the heat exchanger shell 1, a stabilizing component 7 on the outside of the heat exchanger shell 1, the stabilizing component 7 including a fixed bracket 701 on the lower side of the heat exchanger shell 1, a supporting base 702 installed on the inner side of the fixed bracket 701, a fixed ring frame 704 movably connected to the upper side of the heat exchanger shell 1, a buffer support column 706 welded to the bottom end of the supporting base 702, and a fixed base plate 707 welded to the bottom end of the buffer support column 706.

[0031] Furthermore, a buffer spring 708 is installed inside the buffer support 706, and a shock-absorbing damper 709 is installed on the inner side of the buffer spring 708. The shock-absorbing damper 709 is welded to the buffer support 706. When the locomotive is running, the vibration generated will be absorbed by the buffer support 706 first, and then the buffer spring 708 will further alleviate the vibration energy. The shock-absorbing damper 709 can effectively dissipate this energy and prevent the vibration from being transmitted to the heat exchanger shell 1, thereby avoiding the loosening and wear of internal components, extending the service life of the heat exchanger, and enhancing the stability of the heat exchanger in complex vibration environments.

[0032] Furthermore, a buffer pad 703 is bonded to the inner wall of the fixed bracket 701 and the inner wall of the fixed ring bracket 704. The buffer pad 703 is made of rubber. The buffer pad 703 can effectively reduce the impact and friction of the heat exchanger shell 1 in the vibration environment, protect the heat exchanger shell 1 from damage, reduce noise generation, and improve the durability and user comfort of the heat exchanger.

[0033] Furthermore, all cold flow pipes 3 are connected to the cold flow inlet 2. The cold flow pipes 3 are evenly distributed within the heat exchanger shell 1. By setting the cold flow pipes 3, the cold flow can be evenly distributed within the heat exchanger shell 1, thereby improving the efficiency of heat exchange.

[0034] Furthermore, baffles 6 are installed between the cold flow tubes 3. The baffles 6 have a 300° fan-shaped structure and five sets of baffles 6 are provided. The baffles 6 are evenly distributed at equal distances and the notches of the baffles 6 are arranged in a relatively sequential manner. When the hot flow enters the heat exchanger shell 1, the baffles 6 can guide the flow direction of the hot flow, increase the flow path of the fluid in the heat exchanger shell 1, and thus improve the sufficiency and efficiency of heat exchange.

[0035] Furthermore, a hydraulic support column 710 is installed at the center of the fixed base plate 707. The hydraulic support column 710 is attached to the bottom end of the support base 702. Three sets of hydraulic support columns 710 are provided. The hydraulic support columns 710 provide additional support for the heat exchanger to ensure overall stability. At the same time, the hydraulic support columns 710 also have a certain shock absorption function, which can further reduce the impact of vibration on the heat exchanger shell 1 and ensure the smooth operation of the heat exchanger shell 1.

[0036] Furthermore, fixing bolts 705 are provided on both sides of the fixing ring frame 704. The fixing bolts 705 and the fixing bracket 701 are connected by threads. By setting the fixing bolts 705, the tightness between the fixing ring frame 704 and the fixing bracket 701 can be easily adjusted, thereby ensuring the stability of the heat exchanger shell 1 during operation and preventing loosening or damage caused by vibration.

[0037] Working principle: The device is moved to the working position, and the heat exchanger shell 1 is placed on the fixed support 701. The heat exchanger shell 1 is then fixed by the fixed ring 704. Cooling fluid is then introduced through the cold inlet 2, while hot fluid enters the heat exchanger shell 1 through the hot inlet 4, exchanging heat with the cooling fluid. During this heat exchange, the baffle 6 effectively guides the flow direction of the hot fluid, increasing the flow path of the fluid within the heat exchanger shell 1. When the railway locomotive is running, the resulting vibrations are first absorbed by the buffer support 706, and the buffer spring 708 inside the buffer support 706 further alleviates the vibrations. Vibration energy is absorbed by the damping 709, which effectively prevents vibration from being transmitted to the heat exchanger shell 1, avoiding loosening and wear of internal components. At the same time, the buffer pads 703 on the inner walls of the fixed bracket 701 and the fixed ring frame 704 also reduce impact and friction, further protecting the heat exchanger shell 1. Finally, the hydraulic support column 710 provides additional support for the heat exchanger shell 1, ensuring overall stability. The hydraulic support column 710 also has a certain damping function, which can further reduce the impact of vibration on the heat exchanger shell 1. This completes the process of using a high-efficiency heat exchanger for railway locomotives.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
