Abstract
Description
Technical Field
[0001] The utility model relates to the field of servo motors. More specifically, the utility model relates to a servo motor housing that is convenient for heat dissipation. Background Art
[0002] Servo motors generate heat during operation, especially some high-power servo motors generate more heat. Prolonged use will not only affect the normal use of the motor but also affect the performance of the motor itself, and ultimately reduce the service life of the motor. Therefore, it is necessary to use an external structure to dissipate the heat generated by the servo motor externally to achieve cooling and ensure the safe and stable operation of the servo motor. The heat generated by the servo motor during operation is mainly achieved through the heat exchange between its housing and the outside world. Usually, in order to increase the heat dissipation effect of the housing, heat sinks are also arranged outside the housing for heat dissipation. In addition, a fan can be installed inside the housing to improve the air exchange between the inside of the housing and the outside world to dissipate heat from the motor, and the fan is driven by the rotating shaft of the motor to rotate synchronously to dissipate heat from the motor. However, when working in a working environment with a relatively high temperature, only through the natural heat dissipation of the housing, the heat dissipation effect of the servo motor is too poor, and since the temperature of the air entering the housing is already very high due to the high working environment temperature, the effect of using a fan for heat dissipation is also not good. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a servo motor housing that is convenient for heat dissipation, which uses liquid cooling to cool down, and at the same time can cool down the gas entering the housing, thereby improving the heat dissipation effect inside the housing.
[0004] The technical solution of the utility model to solve the above technical problems is as follows: A servo motor housing that is convenient for heat dissipation, including a housing, an air outlet is provided at the rear end of the housing, and further includes:
[0005] A sleeve, which is sleeved on the housing, the inside of the sleeve is hollow, and an inlet pipe and an outlet pipe communicating with its inside are provided thereon;
[0006] A coolant circulation mechanism, which is respectively communicated with the inlet pipe and the outlet pipe;
[0007] Multiple air supply pipes, which penetrate through the sleeve, and one end thereof passes through the housing and communicates with its inside.

Therefore, it should not be construed as a limitation to the present utility model.
[0031] Figures 1 - 5 A servo motor housing for facilitating heat dissipation provided by an embodiment of the present utility model includes a housing 1. An air outlet is provided at the rear end of the housing 1. It further includes:
[0032] A sleeve 2 which is sleeved on the housing 1. The inside of the sleeve 2 is hollow, and a liquid inlet pipe 3 and a liquid outlet pipe 4 communicating with its inside are provided thereon;
[0033] A coolant circulation mechanism which is respectively communicated with the liquid inlet pipe 3 and the liquid outlet pipe 4;
[0034] Multiple air supply pipes 5 which penetrate through the sleeve 2, and one end of which passes through the housing 1 and communicates with its inside. The multiple air supply pipes 5 are evenly distributed on the sleeve 2, and can supply air to the inside of the housing 1 more evenly.
[0035] In this embodiment, a rotor, a stator and a rotor shaft are generally installed inside the servo motor housing 1. A cooling fan is also installed on the rotor shaft. The air inside the housing 1 is discharged through the air outlet at the rear end of the housing 1 by the cooling fan. In this embodiment, the inside of the housing 1 is communicated with the outside through multiple air supply pipes 5, and the outside air enters the inside of the housing 1 through the multiple air supply pipes 5. The air inside the servo motor housing 1 is driven by the cooling fan, and the outside air enters the inside of the housing 1 through the multiple air supply pipes 5 and then leaves the housing 1 from the air outlet at the rear end of the housing 1. During this process, the inside of the housing 1 can be cooled by the flow between the housing 1 and the external air. In this embodiment, after the coolant circulation mechanism sends the low-temperature coolant from the liquid inlet pipe 3 into the sleeve 2, it then flows out from the liquid outlet pipe 4 and is cooled and then sent into the sleeve 2 again to form a circulation of the coolant. During this process, the housing 1 can be cooled by the circulation of the coolant. Water can be used as the coolant. At the same time, the coolant inside the sleeve 2 can also cool the air flowing through the air supply pipe 5, reduce the temperature of the air entering the housing 1, and improve the heat dissipation effect on the housing 1. In this embodiment, liquid cooling and air cooling are combined to dissipate heat from the inside of the servo motor housing 1. Compared with single air cooling or liquid cooling, the heat dissipation effect can be significantly enhanced, enabling the servo motor to operate stably in a working environment with a relatively high temperature.
[0036] Preferably, as another embodiment of the present invention, it further includes:
[0037] A partition 6, which is arranged inside the sleeve 2 to partition the inside of the sleeve 2, as Figure 3 shown, the liquid inlet pipe 3 and the liquid outlet pipe 4 are respectively located on both sides of the partition 6.
[0038] In this embodiment, the inside of the sleeve 2 is partitioned by the partition 6, and the liquid inlet pipe 3 and the liquid outlet pipe 4 are respectively communicated with the parts inside the sleeve 2 located on both sides of the partition 6, so as to extend the distance that the coolant flows through inside the sleeve 2, and thus enable more sufficient heat exchange between the coolant and the sleeve 2a.
[0039] Preferably, as another embodiment of the present invention, the coolant circulation mechanism includes:
[0040] A box body 12, which is communicated with the liquid inlet pipe 3 through a first pipeline 7,
[0041] A water pump 13, whose water inlet and water outlet are respectively communicated with the box body 12 and the liquid inlet pipe 3 through a second pipeline 14;
[0042] A cooling box, and the first pipeline 7 penetrates through the cooling box.
[0043] In this embodiment, the water pump 13 causes the coolant to circulate between the box body 12 and the sleeve 2. The low-temperature coolant in the box body 12 is sent to the inside of the sleeve 2 through the second pipeline 14. The coolant inside the sleeve 2 flows from the inside of the sleeve 2 to the box body 12 through the first pipeline 7, and passes through the cooling box during this process. The cooling box cools the coolant, and the cooled coolant returns to the box body 12. Specifically, as one specific implementation manner, as Figure 6 shown, the cooling box includes: a box body 8, which contains coolant inside, and the first pipeline 7 penetrates through the box body 8; a thermoelectric cooler 9, which is arranged on the outer side wall of the box body 8. The box body 8 is cooled by the thermoelectric cooler 9, and the temperature of the coolant inside the box body 8 is reduced, so as to cool the first pipeline 7 passing through the box body 8.
[0044] Preferably, as another embodiment of the present invention, it further includes:
[0045] a blowing mechanism, the air outlet of which is communicated with the other ends of the plurality of air supply pipes 5.
[0046] In this embodiment, as one specific implementation manner, the blowing mechanism includes: an annular pipe 10, which is sleeved on the sleeve 2, the other ends of the air supply pipes 5 extend into the annular pipe 10 and are communicated with it, and the annular pipe 10 is communicated with an external air source. The external air source sends air into the annular pipe 10 through the third pipeline 11. The air in the annular pipe 10 enters each air supply pipe 5 and is sent into the machine shell 1 through the air supply pipes 5.
