Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] The heat exchanger for internal combustion locomotives disclosed in this utility model is mainly used in situations where internal combustion locomotives are usually in motion, which causes the heat exchanger to be in a vibrating environment for a long time, thus easily leading to damage to the heat exchanger.

[0021] Reference Figures 1-4 A heat exchanger for internal combustion locomotives includes: a heat exchange body 7, on which a mounting flange 3 is provided, and a beveled part 1 is also provided; an external water inlet 5, which is located on the heat exchange body 7, and an external water return 6, on which the input end of the external water return 6 is connected to the output end of the external water inlet 5 via a pipe located inside the heat exchange body 7; an oil return port 4, which is located on the heat exchange body 7; and a vibration damping and protection module 2, which is located on the mounting flange 3 and the heat exchange body 7, and includes multiple damping spring rods 210 and multiple annular elastic elements 212.

[0022] Reference Figures 1-4 In a preferred embodiment, the vibration damping and protection module 2 further includes: a plurality of fixing screws 202, each of which is mounted on the mounting flange 3 and each of which is provided with a fixing nut 201; and a fixing outer ring 203, which is mounted on the plurality of fixing screws 202.

[0023] In this utility model, the vibration damping and protection module 2 also includes: multiple vibration damping rods 207, all of which are disposed on the fixed outer ring 203, and each of the multiple vibration damping rods 207 is provided with a protective outer plate 205.

[0024] In this utility model, the vibration damping and protection module 2 further includes: multiple rubber pads 206, which are respectively disposed on multiple protective outer plates 205; and a fixing plate 208, which is disposed on the heat exchange body 7.

[0025] In this utility model, the vibration damping and protection module 2 further includes: multiple vibration damping sleeve rods 209, all of which are disposed on the fixed plate 208, and each of the multiple vibration damping sleeve rods 209 has a vibration damping cavity 213. Multiple damping spring rods 210 are respectively disposed inside the multiple vibration damping cavities 213, and one end of each of the multiple damping spring rods 210 is connected to one end of each of the multiple vibration damping rods 207.

[0026] In this utility model, the vibration damping and protection module 2 further includes: multiple rubber limiting plates 211, which are respectively disposed on multiple vibration damping rods 207. The outer walls of the multiple rubber limiting plates 211 are respectively in contact with the inner walls of multiple vibration damping cavities 213, and each annular elastic element 212 is disposed between two adjacent rubber limiting plates 211.

[0027] In this utility model, the vibration reduction and protection module 2 also includes: multiple reinforcing trusses 204, all of which are disposed on the heat exchange body 7.

[0028] It should be noted that the vibration reduction and protection module 2 can reduce vibration through the damping spring rod 210 and the annular elastic element 212, and further reduce the vibration generated during the operation of the diesel locomotive through the cooperation of the damping spring rod 210 and the annular elastic element 212 in different directions. This reduces fatigue or stress concentration damage to the heat exchanger caused by long-term vibration, increases the service life of the device, and strengthens the structure of the heat exchange body 7 through the reinforcing truss 204 during use, improving the vibration resistance and further increasing the service life of the device. During use, the outer protective plate 205 and the rubber pad 206 can protect the outer wall of the heat exchange body 7, preventing vibration from causing the heat exchange body 7 to come into direct contact with other structures on the diesel locomotive. At the same time, the soft contact of the rubber pad 206 can prevent excessive wear.

[0029] Working principle: During use, high-frequency vibrations are transmitted to the heat exchanger body 7 as the internal combustion locomotive runs. At this time, the vibrations can be transmitted to the damping rod 207 and the damping sleeve rod 209 respectively through the fixed outer ring 203 and the fixed plate 208. As the vibrations are transmitted, the damping springs inside the damping cavity 213 deform, thereby damping the vibration. During vibration damping, the damping springs in multiple directions can cooperate with each other. The damping spring in one direction compresses the damping springs in other directions and stretches them to improve the damping effect. At the same time, the annular elastic element 212 can absorb the lateral vibration force between the damping rod 207 and the damping sleeve rod 209 during vibration damping, further cooperating with the damping springs to reduce the vibration. The protective outer plate 205 can prevent vibration from causing direct collision between the other structures of the internal combustion locomotive and the heat exchange body 7. At the same time, the soft contact of the rubber pad layer 206 can prevent excessive wear.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
