Description

Technical Field

[0001] The utility model relates to the technical field of locomotive cooling fan motors, in particular to a cooling channel of a locomotive cooling fan motor. Background Art

[0002] Diesel locomotives use a suction-type cooling device with a motor-driven fan. If an AC motor is used in the suction-type cooling device, cooling the AC motor becomes a major technical challenge. When the cooling air passes through the radiator, the temperature rises to 60-80°C. This high temperature environment is not conducive to the normal operation of the motor and seriously shortens the service life of the motor. The existing motor casing is generally completely sealed and fixed. The heat generated by the motor cannot be dissipated quickly, which in turn affects the working efficiency and stability of the motor performance.

[0003] In summary, the present application now proposes a cooling channel for a locomotive cooling fan motor to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a cooling channel for a locomotive cooling fan motor, which can solve the problem that the existing motor housing is generally in a completely sealed and fixed state, and the heat generated by the motor cannot be dissipated quickly, thereby affecting the working efficiency of the motor and the stability of the motor performance.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a cooling channel for a locomotive cooling fan motor, comprising:

[0006] A cooling fan, wherein a fan motor is provided on one side of the cooling fan, and a housing is provided on the outside of the fan motor;

[0007] A cooling assembly is provided on the housing. The cooling assembly includes a cooling pipe, a liquid inlet pipe, and a liquid outlet pipe. The cooling pipe is wound around the fan motor. The liquid inlet pipe is fixedly installed at one end of the cooling pipe, and the liquid outlet pipe is fixedly installed at the other end of the cooling pipe.

[0008] The buffer component is arranged on the shell.

[0009] Preferably, a mounting plate is provided on one side of the cooling fan, and the cooling fan and the mounting plate are fixedly installed by bolts. One side of the mounting plate is fixedly installed to one side of the shell, which does not change the structure of the fan motor itself and does not affect the operation of the fan motor itself. The structure is simple and it is easy to disassemble and install.

[0010] Preferably, the cooling assembly also includes a fixed sleeve, the other ends of the liquid inlet pipe and the liquid outlet pipe extend to the outside of the shell, and the top of the fixed sleeve is fixedly installed with the inner wall of the shell. Wrapping the cooling pipe around the outside of the fan motor can directly transfer the cooling medium through the surface of the fan motor, effectively taking away the heat generated by the fan motor, and can quickly and evenly reduce the operating temperature of the fan motor, improve its heat dissipation efficiency, and effectively utilize limited space. The design of the cooling pipe can reduce the damage and failure rate of internal components of the fan motor due to thermal stress, and extend the service life and reliability of the fan motor by keeping the fan motor running at a lower operating temperature.

[0011] Preferably, the buffer assembly includes a spring clamp frame and a spring, and multiple groups of springs are fixedly installed on the inner wall of one side of the shell. One end of the fan motor is clamped and installed with the spring clamp frame, and the other end of the spring is fixedly installed on the outer wall of one side of the spring clamp frame. A damper is provided inside the spring. The spring clamp frame can effectively fix the end of the fan motor, which can not only prevent the fan motor from loosening due to vibration or external impact, but also ensure the normal circulation of the cooling pipe inside the equipment, thereby maintaining stable heat dissipation efficiency. By simply compressing or releasing the spring clamp frame, it can be quickly installed or removed, which is convenient for cleaning, maintenance or replacement of required parts, saving maintenance time and cost.

[0012] Preferably, a heat sink is fixedly mounted on the outer wall of the shell, which can slow down the increase in the temperature of the coolant itself and reduce the frequency of replacing the coolant.

[0013] Preferably, a heat dissipation hole is provided on one side of the shell to facilitate the dissipation of heat.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The cooling channel of the cooling fan motor of the locomotive is used in conjunction with the cooling pipe, the liquid inlet pipe, the liquid outlet pipe and the fixed sleeve. The cooling pipe is wrapped around the outside of the fan motor to directly transfer the cooling medium through the surface of the fan motor, effectively taking away the heat generated by the fan motor, and can quickly and evenly reduce the operating temperature of the fan motor, improve its heat dissipation efficiency, and effectively utilize limited space. The design of the cooling pipe can reduce the damage and failure rate of the internal components of the fan motor caused by thermal stress, and extend the service life and reliability of the fan motor by keeping the fan motor running at a lower operating temperature.

[0016] (2) The cooling channel of the locomotive cooling fan motor is used in conjunction with the fan motor, housing, spring clamp and spring.

By simply compressing or releasing the spring clamp, it can be quickly installed or removed, which is convenient for cleaning, maintenance or replacement of required parts, saving maintenance time and cost.

[0024] See also Figure 1-4 The utility model provides a technical solution: a cooling channel of a locomotive cooling fan motor, comprising a cooling fan 1, a cooling assembly and a buffer assembly. A fan motor 2 is provided on one side of the cooling fan 1, a shell 4 is provided on the outside of the fan motor 2, and the cooling assembly is provided on the shell 4. The cooling assembly includes a cooling pipe 5, a liquid inlet pipe 6 and a liquid outlet pipe 7. The cooling pipe 5 is wound and installed on the fan motor 2. The liquid inlet pipe 6 is fixedly installed at one end of the cooling pipe 5, and the liquid outlet pipe 7 is fixedly installed at the other end of the cooling pipe 5. The buffer assembly is provided on the shell 4.

[0025] Furthermore, a mounting plate 3 is provided on one side of the cooling fan 1. The cooling fan 1 and the mounting plate 3 are fixedly installed by bolts. One side of the mounting plate 3 is fixedly installed to one side of the shell 4, without changing the structure of the fan motor 2 itself and affecting the operation of the fan motor 2 itself. The structure is simple and it is easy to disassemble and install.

[0026] Furthermore, the cooling assembly also includes a fixed sleeve 8, and the other ends of the liquid inlet pipe 6 and the liquid outlet pipe 7 extend to the outside of the shell 4. The top of the fixed sleeve 8 is fixedly installed on the inner wall of the shell 4, and the coolant is transported to the inside of the cooling pipe 5 through the liquid inlet pipe 6, and then discharged through the liquid inlet pipe 6 to form a cycle. Wrapping the cooling pipe 5 around the outside of the fan motor 2 can directly transfer the cooling medium through the surface of the fan motor 2, effectively taking away the heat generated by the fan motor 2, and can quickly and evenly reduce the operating temperature of the fan motor 2, improve its heat dissipation efficiency, and at the same time effectively utilize limited space. The design of the cooling pipe 5 can reduce the damage and failure rate of the internal components of the fan motor 2 due to thermal stress, and by keeping the fan motor 2 running at a lower operating temperature, the service life and reliability of the fan motor 2 are extended.

[0027] Furthermore, the buffer assembly includes a spring clamping frame 9 and a spring 10. Multiple groups of springs 10 are fixedly installed on the inner wall of one side of the housing 4. One end of the fan motor 2 is clamped and installed with the spring clamping frame 9, and the other end of the spring 10 is fixedly installed on the outer wall of one side of the spring clamping frame 9. A damper is provided inside the spring 10, which contacts the fan motor 2 on the housing 4 with one side of the cooling fan 1, so that the cooling pipe 5 inside the housing 4 is sleeved on the outer wall of the fan motor 2. At the same time, the spring clamping frame 9 on the housing 4 clamps one end of the fan motor 2. When the fan motor 2 vibrates during operation, the vibration force is transmitted to the spring clamping frame 9, and then the vibration force is buffered by the spring 10 on the spring clamping frame 9. The spring clamping frame 9 can effectively fix the end of the fan motor 2, which can not only prevent the fan motor 2 from loosening due to vibration or external impact, but also ensure the normal circulation of the cooling pipe 5 inside the equipment, thereby maintaining stable heat dissipation efficiency. By simply compressing or releasing the spring clamping frame 9, it can be quickly installed or removed, which is convenient for cleaning, maintenance or replacement of required parts, saving maintenance time and cost.

[0028] Furthermore, a heat sink 11 is fixedly mounted on the outer wall of the housing 4, which can slow down the increase in the temperature of the coolant itself and reduce the frequency of replacing the coolant.

[0029] Secondly, a heat dissipation hole 12 is opened on one side of the shell 4 to facilitate the dissipation of heat.

[0030] Working principle: When in use, the shell 4 is fixedly installed on the cooling fan 1. First, the fan motor 2 on the shell 4 is in contact with one side of the cooling fan 1, so that the cooling pipe 5 inside the shell 4 is sleeved on the outer wall of the fan motor 2, and at the same time, the spring clamp frame 9 on the shell 4 clamps one end of the fan motor 2, and makes the mounting plate 3 completely fit with the cooling fan 1, and the cooling fan 1 and the mounting plate 3 are installed and fixed by bolts. When the fan motor 2 drives the cooling fan 1 for use, the coolant is transported to the inside of the cooling pipe 5 through the liquid inlet pipe 6, and then discharged through the liquid inlet pipe 6, forming a cycle to take away the heat from the surface of the fan motor 2. When the fan motor 2 vibrates during operation, the vibration force is transmitted to the spring clamp frame 9, and then the vibration force is buffered by the spring 10 on the spring clamp frame 9.

Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
