[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] Please refer to Figure 1In order to achieve the above-mentioned purpose, an embodiment of the present invention provides a motor cooler, comprising: a cooler housing 1, on which an air inlet 11, an air outlet 12, a first connecting port 13 and a second connecting port 14 are provided, and the air inlet 11 and the air outlet 12 are both connected to the internal space of the cooler housing 1; a first baffle structure 2, which is arranged inside the cooler housing 1, and the first baffle structure 2 divides the internal space of the cooler housing 1 into an air inlet duct 10 and an air outlet duct 20, and the air inlet 11 and the first connecting port 13 are both connected to the air inlet duct 1 0 is connected, the air inlet 11 and the first connecting port 13 are arranged at intervals along the extension direction of the air inlet duct 10, the second connecting port 14 and the air outlet 12 are both connected to the air outlet duct 20, and the second connecting port 14 and the air outlet 12 are arranged at intervals along the extension direction of the air outlet duct 20; the second baffle structure 3 is arranged on the air inlet duct 10, along the extension direction of the air inlet duct 10, the second baffle structure 3 and the inner wall of the cooler shell 1 divide the air inlet duct into a plurality of reversing portions 101, and at the reversing portion 101, the extension direction of the air inlet duct 10 changes.

[0024] The motor cooler adopts this structural design, and its second partition structure 3 and cooler housing 1 separate the air inlet duct 10 of the inner wall of the motor cooler into multiple reversing parts 101, and the extension direction of the air inlet duct 10 at the reversing part 101 changes. Due to the presence of multiple reversing parts 101, foreign matter such as water and particles outside the motor cooler can be intercepted by the reversing part 101, thereby preventing them from entering the interior of the motor later. Compared with the motor adopting the IC01 cooling method in the related art, the motor cooler adopting this structural design has effectively improved the protection of the motor, and solves the technical problem of poor protection performance of the motor adopting the IC01 cooling method in the related art, and is particularly suitable for use in some scenarios with high requirements for motor protection.

[0025] In a specific embodiment, the number of the reversing parts 101 is three, and the angle of change of the air intake duct 10 in the extension direction of the reversing part 101 is 90°. The second baffle structure 3 includes a first plate body 31 and a second plate body 33, and the first plate body 31 and the second plate body 33 are arranged at an angle of 90°. This design with a larger mutation angle of 90° can more effectively intercept foreign matter entering the motor cooler, thereby ensuring the subsequent reliable operation of the motor. By designing the reversing parts 101 to be three, it has been proven in practice that there is a higher interception rate for foreign matter entering from the outside, which can effectively improve the motor protection performance while ensuring the simplicity of the motor cooler structure.

[0026] Specifically, the second baffle structure 3 also includes a third plate 32, which is located between the first plate 31 and the second plate 33 and connects the two. The third plate 32 is arranged at an obtuse angle to the first plate 31, and the third plate 32 is arranged at an obtuse angle to the second plate 33. In this embodiment, by designing the third plate 32, and the third plate 32 is arranged at an obtuse angle to the first plate 31, and the third plate 32 is arranged at an obtuse angle to the second plate 33, the presence of the third plate 32 can guide the air in the air intake duct 10, which is beneficial to reducing wind resistance, increasing air flow, and thus ensuring the heat dissipation effect of the motor.

[0027] In this embodiment, the first baffle structure 2 includes a fourth plate body 21 and a fifth plate body 22, the fourth plate body 21 is parallel to the first plate body 31, and the fifth plate body 22 is inclined relative to the fourth plate body 21 toward the rear of the air inlet duct 10. The space inside the cooler housing 1 is divided into the air inlet duct 10 and the air outlet duct 20 by designing the fourth plate body 21 and the fifth plate body 22. On this basis, the inclined fifth plate body 22 is designed, which can guide the air in the air inlet duct 10, which is conducive to reducing wind resistance, increasing air flow, and thus ensuring the heat dissipation effect of the motor.

[0028] like Figure 1 and Figure 2 As shown, a rain shield 4 is provided at the air inlet 11 and / or the air outlet 12. When the motor cooler is placed in a working posture, at least part of the rain shield 4 is arranged to be inclined to the horizontal plane. By designing the rain shield 4 at the air inlet 11 and / or the air outlet 12, the risk of rainwater entering the motor cooler can be further reduced, thereby ensuring the protection effect of the motor. It should be noted that when the rain shield 4 is provided at the air inlet 11 and the air outlet 12, there are two rain shields 4, one of which is provided at the air inlet 11, and the other is provided at the air outlet 12.

[0029] In a preferred embodiment, the motor cooler further includes a filter 5, which is disposed between the air inlet 11 and the air outlet 12 to filter the air entering the motor cooler through the filter 5. By designing the filter 5 between the air inlet 11 and the air outlet 12, the air entering the motor cooler can be filtered to remove some foreign matter therein, thereby ensuring that the air is subsequently used to dissipate heat from the motor with less impact on the motor, thereby facilitating reliable operation of the motor.

[0030] In a specific embodiment, the motor cooler further includes a third baffle structure 6, which is disposed on the air inlet duct 10 and blocks the air inlet duct 10, wherein the filter 5 is disposed on the third baffle structure 6. In this embodiment, the third baffle structure 6 blocks the air inlet duct 10, and the filter 5 is disposed on the third baffle structure 6, so that all the air entering the motor cooler will be filtered through the filter 5 to ensure the filtering effect. Preferably, in order to facilitate the replacement of the filter 5, the filter 5 adopts a pull-out matching structure (drawer type) to match the third baffle structure 6.

[0031] Specifically, when the motor cooler is placed in the working posture, along the extension direction of the air intake duct 10, at least part of the air intake duct 10 is raised. In this way, foreign objects entering the motor cooler need to climb a certain height when passing through the air intake duct 10, which further increases the difficulty of foreign objects passing through the air intake duct 10, which is conducive to improving the interception effect of the motor cooler on foreign objects, thereby improving the protection of the motor.

[0032] like Figures 2 to 3 As shown, an embodiment of the present invention further provides a motor, which includes a base 71, a stator structure 72, a rotor structure 73, and a fan impeller 74. The stator structure 72 and the rotor structure 73 are both installed in the base 71, and the fan impeller 74 is installed on the rotating shaft 730 of the rotor structure 73; the motor also includes the above-mentioned motor cooler, the first connecting port 13 of the motor cooler is connected to the first chamber inside the base 71, and the second connecting port 14 of the motor cooler is connected to the second chamber inside the base 71, and the first chamber and the second chamber are respectively arranged at the two ends of the stator structure 72 along the axial direction of the motor.

[0033] Specifically, the motor also includes two end covers and two bearing devices. The two end covers are arranged one by one at the two ends of the base 71 along the axial direction of the motor, and the two bearing devices are arranged one by one at the two end covers. The rotating shaft 730 of the rotor structure 73 cooperates with the two bearing devices. The rotor structure 73 of the motor is a copper bar rotor with a ribbed shaft. Compared with the motor in the related art, the motor with the above-mentioned structural design in the embodiment of the present invention has an improved rotor structure. The rotor is a copper bar rotor structure with a ribbed shaft. The ribs and the shaft are forged as one body, which is suitable for reciprocating compressor loads and effectively avoids the risk of broken shafts. Compared with the existing Y series motors, the cooler design is improved and suitable for outdoor use. The cooler design complies with the NEMA standard climate protection motor. In the air channel of the cooler, at least three direction changes are formed, each change is not less than 90°, and a replaceable stainless steel filter is provided at the air inlet. Compared with the existing motors, the power density is improved, and one center height is reduced based on the existing center height spectrum. Compared with existing motors, the overall performance of the motor reflects the energy-saving and reliable characteristics of smaller size, lighter weight, higher efficiency, lower noise, less vibration, easy use and maintenance, etc. It is also suitable for North American CLASS I, DIVISION 2 GROUPS A, B, C, D, T3 explosion-proof environment.

[0034] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0035] The motor cooler of the embodiment of the present invention comprises: a cooler housing 1, on which an air inlet 11, an air outlet 12, a first connecting port 13 and a second connecting port 14 are provided, the air inlet 11 and the air outlet 12 are both connected to the inner space of the cooler housing 1; a first baffle structure 2, which is arranged inside the cooler housing 1, and the first baffle structure 2 divides the inner space of the cooler housing 1 into an air inlet duct 10 and an air outlet duct 20, the air inlet 11 and the first connecting port 13 are both connected to the air inlet duct 10, the air inlet 11 and the first connecting port 13 are arranged at intervals along the extension direction of the air inlet duct 10, the second connecting port 14 and the air outlet 12 are both connected to the air outlet duct 20, and the second connecting port 14 and the air outlet 12 are arranged at intervals along the extension direction of the air outlet duct 20; the second partition structure 3, the second partition structure 3 is arranged on the air inlet duct 10, along the extension direction of the air inlet duct 10, the second partition structure 3 and the inner wall of the cooler shell 1 divide the air inlet duct into a plurality of reversing portions 101, and at the reversing portion 101, the extension direction of the air inlet duct 10 changes.

[0036] The motor cooler adopts this structural design, and its second partition structure 3 and cooler housing 1 separate the air inlet duct 10 of the inner wall of the motor cooler into multiple reversing parts 101, and the extension direction of the air inlet duct 10 at the reversing part 101 changes. Due to the presence of multiple reversing parts 101, foreign matter such as water and particles outside the motor cooler can be intercepted by the reversing part 101, thereby preventing them from entering the interior of the motor later. Compared with the motor adopting the IC01 cooling method in the related art, the motor cooler adopting this structural design has effectively improved the protection of the motor, and solves the technical problem of poor protection performance of the motor adopting the IC01 cooling method in the related art, and is particularly suitable for use in some scenarios with high requirements for motor protection.
