Description
Technical Field
[0001] This invention relates to the field of marine motor technology, and more specifically, to a motor assembly and a ship. Background Technology
[0002] Currently, in related technologies, ship motors are usually installed inside the cabin and operate. The motors generate heat when they are running. Marine motors are usually air-cooled motors, which means that the motors are cooled by air. However, when the motors work in the closed cabin for a long time, the environmental limitations of the closed cabin result in poor heat dissipation of the motors, which increases energy consumption. Summary of the Invention
[0003] The present invention aims to at least solve the technical problem in the prior art or related technologies that the motor is cooled by air, but when the motor works in a closed chamber for a long time, the heat dissipation effect of the motor is poor due to the environmental limitation of the closed chamber, resulting in increased energy consumption.
[0004] Therefore, a first aspect of the present invention provides a motor assembly.
[0005] A second aspect of the invention provides for a ship.
[0006] In view of the above, a first aspect of the present invention provides a motor assembly, the motor assembly including a motor, a heat exchanger, a first temperature sensor, a second temperature sensor, and a drive component. The motor includes a first housing having a cooling channel, a first liquid inlet, and a first liquid outlet, the first liquid inlet and the first liquid outlet respectively communicating with the cooling channel; the heat exchanger has a second liquid inlet and a second liquid outlet, the first liquid inlet communicating with the second liquid outlet, the first liquid outlet communicating with the second liquid inlet, a first cooling medium flowing between the first housing and the heat exchanger, and the first cooling medium being able to exchange heat with a second cooling medium within the heat exchanger; the first temperature sensor is disposed in the heat exchanger for detecting a first temperature at the second liquid inlet; the second temperature sensor is disposed in the heat exchanger for detecting a second temperature at the second liquid outlet; one end of the drive component is communicating with the first liquid inlet, the other end of the drive component is communicating with the second liquid outlet, and the drive component is capable of adjusting the flow rate of the first cooling medium according to the temperature difference between the first temperature and the second temperature.
[0007] In this technical solution, the motor assembly includes a motor, a heat exchanger, a first temperature sensor, a second temperature sensor, and a drive component. The motor includes a first housing, which protects the internal components of the motor. The first housing has a cooling channel, a first liquid inlet, and a first liquid outlet, allowing for the arrangement of the cooling channel, the first liquid inlet, and the first liquid outlet.
[0008] The heat exchanger has a second inlet and a second outlet, with the first inlet connected to the second outlet and vice versa, to facilitate its arrangement. The heat exchanger is located outside the first housing. A first cooling medium circulates between the first housing and the heat exchanger, allowing the first cooling medium to flow within both. During operation, the motor generates heat, which is transferred to the outside through the first housing. The first cooling medium enters the cooling channel through the first inlet and exits through the first outlet. As it flows through the cooling channel, it carries away heat from the first housing, thus dissipating heat from the motor. The first cooling medium can also exchange heat with a second cooling medium within the heat exchanger; that is, after exiting the first outlet, the first cooling medium exchanges heat with the second cooling medium in the heat exchanger, thereby lowering its temperature so that it can continue flowing into the first housing to dissipate heat from the motor.
[0009] A first temperature sensor is installed in the heat exchanger to detect the first temperature at the second liquid inlet, thus enabling the installation and fixation of the first temperature sensor. A second temperature sensor is installed in the heat exchanger to detect the second temperature at the second liquid outlet, thus enabling the installation and fixation of the second temperature sensor. By installing both the first and second temperature sensors in the heat exchanger, the accuracy of the first and second temperature detections can be improved.
[0010] One end of the drive component is connected to the first liquid inlet, and the other end is connected to the second liquid outlet to enable installation of the drive component. The drive component can adjust the flow rate of the first cooling medium according to the temperature difference between the first temperature and the second temperature, thereby driving the first cooling medium.
[0011] Compared to the air-cooled heat dissipation method used in marine motors, the motor of this invention adopts a liquid-cooled circulating heat dissipation method. Through the efficient heat exchange between the first cooling medium and the heat exchanger, it is not limited by the closed cabin environment and can improve the heat dissipation efficiency. At the same time, by monitoring the temperature difference in real time through the first temperature sensor and the second temperature sensor, the flow rate of the medium is dynamically adjusted by the drive component, and the heat dissipation of the motor is precisely controlled.
[0012] This invention dissipates heat from a motor by incorporating a first temperature sensor, a second temperature sensor, a drive component, and a heat exchanger. The first and second temperature sensors detect the temperature difference between the inlet and outlet liquids of the heat exchanger, thereby determining the motor's current heat dissipation efficiency and thermal load. The drive component dynamically adjusts the flow rate of the first cooling medium based on the temperature difference, ensuring the motor maintains a suitable temperature under different loads and operating conditions. This achieves precise control of the motor's operating temperature, guaranteeing stable and efficient operation, thus improving heat dissipation and extending its service life. Furthermore, based on the detected temperature difference, when the temperature difference increases, the drive component accelerates the circulation of the first cooling medium, improving heat dissipation efficiency; conversely, when the temperature difference decreases, indicating good heat dissipation, reducing the flow rate of the drive component saves energy.
[0013] In some technical solutions of the present invention, optionally, the motor assembly further includes a first pipeline and a second pipeline. The first end of the first pipeline is connected to a first liquid inlet, and the second end of the first pipeline is connected to a second liquid outlet; the first end of the second pipeline is connected to the first liquid outlet, and the second end of the second pipeline is connected to the second liquid inlet, and the driving component is disposed in the first pipeline.
[0014] In this technical solution, the motor assembly also includes a first pipe and a second pipe. The first pipe has a first end connected to a first liquid inlet and a second end connected to a second liquid outlet, thus arranging the first pipe to provide a flow channel for the first cooling medium flowing from the heat exchanger to the first shell. The second pipe has a first end connected to the first liquid outlet and a second end connected to the second liquid inlet, thus arranging the second pipe to provide a flow channel for the first cooling medium flowing from the first shell to the heat exchanger. A drive component is located in the first pipe, allowing direct control of the flow rate of the first cooling medium, improving control efficiency. The first and second pipes provide a channel for the circulating flow of the first cooling medium. Furthermore, by adjusting the arrangement of the first and second pipes, the flow resistance of the first cooling medium can be reduced, improving circulation efficiency. The drive component is located in the first pipe, allowing the drive component to quickly adjust the flow rate of the first cooling medium entering the motor, adapting promptly to changes in the motor's thermal load.
[0015] Optionally, in some technical solutions of the present invention, the motor further includes a first mounting component and a second mounting component. The first and second mounting components are disposed in the first housing. The first mounting component has a first liquid inlet, and the second mounting component has a first liquid outlet. A first end of a first pipeline is connected to the first mounting component, and a first end of the second pipeline is connected to the second mounting component. The heat exchanger includes a second housing, a third mounting component, and a fourth mounting component. The third and fourth mounting components are disposed in the second housing. The third mounting component has a second liquid outlet, and the fourth mounting component has a second liquid inlet. A second end of the first pipeline is connected to the third mounting component, and a second end of the second pipeline is connected to the fourth mounting component.
[0016] In this technical solution, the motor also includes a first mounting component and a second mounting component. The first and second mounting components are disposed on the first housing to achieve installation and fixation of the first and second mounting components. The first mounting component has a first liquid inlet, and the second mounting component has a first liquid outlet, to achieve the arrangement of the first liquid inlet and the first liquid outlet. The first end of the first pipeline is connected to the first mounting component, and the first end of the second pipeline is connected to the second mounting component. By setting the first and second mounting components, in addition to achieving communication between the first end of the first pipeline and the first liquid inlet, and the first end of the second pipeline and the first liquid outlet, the stability of the connection between the first and second pipelines and the first housing can be improved, ensuring the sealing of the connection. The heat exchanger includes a second housing, a third mounting component, and a fourth mounting component. The third and fourth mounting components are disposed on the second housing to achieve installation and fixation of the third and fourth mounting components. The third mounting component has a second liquid outlet, and the fourth mounting component has a second liquid inlet, to achieve the arrangement of the second liquid outlet and the second liquid inlet. The second end of the first pipeline is connected to the third mounting component, and the second end of the second pipeline is connected to the fourth mounting component. By setting up the third and fourth mounting components, in addition to ensuring that the second end of the first pipeline is connected to the second liquid outlet and the second end of the second pipeline is connected to the second liquid inlet, the stability of the connections between the first and second pipelines and the heat exchanger is improved, ensuring the sealing of the connections. Therefore, by setting up the first, second, third, and fourth mounting components, the reliability and sealing of the connections between the motor and the heat exchanger and the first pipeline, respectively, are ensured, as are the connections between the motor and the heat exchanger and the second pipeline, respectively, while also improving the convenience of installation and maintenance. This prevents leakage of the first cooling medium during circulation, ensuring the continuity and effectiveness of the first cooling medium circulation.
[0017] In some technical solutions of the present invention, optionally, a first temperature sensor is disposed on a third mounting component, and a first gap is formed between the first temperature sensor and the second housing; a second temperature sensor is disposed on a fourth mounting component, and a second gap is formed between the second temperature sensor and the second housing.
[0018] In this technical solution, a first temperature sensor is mounted on a third mounting component, with a first gap between the first temperature sensor and the second housing to facilitate its installation and fixation. The first temperature sensor can detect the first temperature at the second liquid outlet at the location of the third mounting component. A second temperature sensor is mounted on a fourth mounting component, with a second gap between the second temperature sensor and the second housing to facilitate its installation and fixation. The second temperature sensor can detect the second temperature at the second liquid inlet at the location of the fourth mounting component. By mounting the second and first temperature sensors on corresponding fourth and third mounting components, this invention can obtain accurate first and second temperatures, thereby obtaining accurate temperature difference changes. Therefore, by rationally arranging the detection points, the temperatures of the first cooling medium entering and exiting the heat exchanger can be directly and accurately obtained, avoiding inaccurate temperature differences caused by detection point deviations. Accurate first and second temperature data can truly reflect the motor's thermal load and heat dissipation efficiency, enabling the drive component to adjust the flow rate of the first cooling medium according to the actual temperature difference, preventing the motor temperature from being too high or too low.
[0019] Optionally, in some technical solutions of the present invention, the heat exchanger further has a third liquid inlet and a third liquid outlet, the second cooling medium enters the heat exchanger through the third liquid inlet and flows out through the third liquid outlet, and the second cooling medium can exchange heat with the first cooling medium.
[0020] In this technical solution, the heat exchanger also has a third inlet and a third outlet to facilitate their arrangement. The second cooling medium enters the heat exchanger through the third inlet and flows out through the third outlet. As it flows through the heat exchanger, the second cooling medium exchanges heat with the first cooling medium. This second cooling medium is an external cooling medium; through heat exchange with the first cooling medium, it can remove the heat absorbed by the first cooling medium from the motor, thus achieving heat transfer and dissipation. By providing the third inlet and third outlet for the flow of the second cooling medium, the first cooling medium absorbs heat from the motor, then exchanges heat with the second cooling medium within the heat exchanger. The second cooling medium carries away the heat and discharges it through the third outlet, completing heat dissipation. This ensures the motor can cool down quickly, maintain stable operation, further reduce energy consumption, and extend the motor's service life.
[0021] In some technical solutions of the present invention, the cooling channel is optionally arranged circumferentially along the first housing.
[0022] In this technical solution, the cooling channels are arranged circumferentially along the first housing to achieve optimal cooling channel layout. By placing the cooling channels inside the first housing, not only can the first cooling medium remove heat from the motor, but it also prevents the first cooling medium from entering the motor and affecting internal components. The cooling channels are arranged circumferentially around the first housing, ensuring uniform heat dissipation and preventing localized overheating from affecting motor operation. The circumferential arrangement of the cooling channels allows the first cooling medium to absorb heat evenly during flow, ensuring a balanced overall motor temperature. Simultaneously, the circumferential arrangement of the cooling channels reduces the flow resistance of the first cooling medium, improving circulation efficiency.
[0023] In some technical solutions of the present invention, optionally, there are multiple cooling channels, which are arranged along the axial direction of the motor and are interconnected.
[0024] In this technical solution, multiple cooling channels are used. These multiple channels increase the heat dissipation area of the motor, thereby improving its heat dissipation efficiency. These multiple cooling channels are arranged along the motor's axial direction and are interconnected. This arrangement expands the contact area between the first cooling medium and the first housing, ensuring that all positions along the motor's axial direction are cooled. The interconnectivity between the multiple cooling channels ensures smooth flow of the first cooling medium, preventing heat accumulation in localized areas and further improving the heat dissipation efficiency of the cooling system. This allows the motor to maintain a uniform temperature even under high load and prolonged operation, reducing energy consumption and extending its service life.
[0025] In some technical solutions of the present invention, the heat exchanger may optionally be arranged radially on the outside of the first housing along the motor.
[0026] In this technical solution, the heat exchanger is arranged radially outside the first housing, meaning it is mounted outside the first housing along the radial direction of the motor and adjacent to it. This connection method shortens the distance between the heat exchanger and the motor, reduces the length of the connecting pipes, and lowers the flow resistance and heat loss of the first cooling medium. Furthermore, the compact installation of the heat exchanger and motor reduces the installation space required for the motor assembly, thus avoiding the occupation of excessive space within the ship's cabin.
[0027] In some technical solutions of the present invention, optionally, the first liquid inlet and the first liquid outlet are arranged radially on the outside of the first housing, and the first liquid outlet is higher than the first liquid inlet along the height direction of the motor.
[0028] In this technical solution, the first liquid inlet and the first liquid outlet are arranged radially on the outside of the first housing of the motor, and the first liquid outlet is higher than the first liquid inlet along the height direction of the motor, thus achieving the proper arrangement of the first liquid inlet and the first liquid outlet. By adjusting the installation positions of the first liquid inlet and the first liquid outlet, when the first cooling medium is added to the cooling channel, because the first liquid inlet is positioned higher, as the first cooling medium is injected, the gas in the cooling channel can be gradually and completely discharged to the outside, avoiding the presence of gas in the cooling channel after the first cooling medium is injected, thus preventing any impact on the motor's heat dissipation effect, increasing the circulation rate of the first cooling medium, and also improving heat dissipation efficiency.
[0029] A second aspect of the present invention provides a ship that includes the motor assembly described in any of the above-described technical solutions.
[0030] In this technical solution, since the ship has the motor assembly of any of the above technical solutions, all the beneficial effects of the motor assembly of any of the above technical solutions will not be elaborated here.

Detailed Implementation
[0046] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.
[0047] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.
[0048] The following reference Figures 1 to 11 The invention describes an electric motor assembly 100 and a ship according to some embodiments of the present invention.
[0049] like Figure 1 , Figure 2 and Figure 3 As shown, a first aspect of the present invention provides a motor assembly 100, which includes a motor 102, a heat exchanger 116, a first temperature sensor 132, a second temperature sensor 134, and a drive component 136. The motor 102 includes a first housing 104 having a cooling channel 106, a first liquid inlet 108, and a first liquid outlet 110, which are respectively connected to the cooling channel 106. The heat exchanger 116 has a second liquid inlet 118 and a second liquid outlet 120, with the first liquid inlet 108 connected to the second liquid outlet 120 and the first liquid outlet 110 connected to the second liquid inlet 118. A first cooling medium flows between the first housing 104 and the heat exchanger 116. The medium can exchange heat with the second cooling medium in the heat exchanger 116; a first temperature sensor 132 is disposed in the heat exchanger 116 to detect the first temperature of the second inlet 118; a second temperature sensor 134 is disposed in the heat exchanger 116 to detect the second temperature of the second outlet 120; one end of the drive component 136 is connected to the first inlet 108, and the other end of the drive component 136 is connected to the second outlet 120, and the drive component 136 can adjust the flow rate of the first cooling medium according to the temperature difference between the first temperature and the second temperature.
[0050] In this embodiment, the motor assembly 100 includes a motor 102, a heat exchanger 116, a first temperature sensor 132, a second temperature sensor 134, and a drive component 136. The motor 102 includes a first housing 104, which protects the internal components of the motor 102. The first housing 104 has a cooling channel 106, a first liquid inlet 108, and a first liquid outlet 110, which are arranged to accommodate the cooling channel 106, the first liquid inlet 108, and the first liquid outlet 110.
[0051] The heat exchanger 116 has a second inlet 118 and a second outlet 120. The first inlet 108 is connected to the second outlet 120, and the first outlet 110 is connected to the second inlet 118, thus arranging the heat exchanger 116. The heat exchanger 116 is located outside the first housing 104. A first cooling medium flows between the first housing 104 and the heat exchanger 116, allowing the first cooling medium to circulate within both the first housing 104 and the heat exchanger 116. Since the motor 102 generates heat during operation, this heat is transferred to the outside through the first housing 104. The first cooling medium can enter the cooling channel 106 through the first inlet 108 and flow out through the first outlet 110. During its flow through the cooling channel 106, the first cooling medium can carry away the heat from the first housing 104, thereby dissipating heat from the motor 102. The first cooling medium can exchange heat with the second cooling medium in the heat exchanger 116. That is, after the first cooling medium flows out from the first outlet 110, it can exchange heat with the second cooling medium in the heat exchanger 116, thereby reducing the temperature of the first cooling medium so that the first cooling medium can continue to flow into the first housing 104 to dissipate heat from the motor 102.
[0052] A first temperature sensor 132 is disposed on the heat exchanger 116 to detect the first temperature at the second liquid inlet 118, thereby enabling the installation and fixation of the first temperature sensor 132. A second temperature sensor 134 is disposed on the heat exchanger 116 to detect the second temperature at the second liquid outlet 120, thereby enabling the installation and fixation of the second temperature sensor 134. By disposing of both the first temperature sensor 132 and the second temperature sensor 134 on the heat exchanger 116, the accuracy of the detection of the first and second temperatures can be improved.
[0053] One end of the driving component 136 is connected to the first liquid inlet 108, and the other end of the driving component 136 is connected to the second liquid outlet 120, thereby enabling the installation of the driving component 136. The driving component 136 can adjust the flow rate of the first cooling medium according to the temperature difference between the first temperature and the second temperature, thereby driving the first cooling medium. The end of the driving component 136 connected to the first liquid inlet 108 is the liquid outlet, and the other end of the driving component 136 connected to the second liquid outlet 120 is the liquid inlet.
[0054] Compared to the air-cooled heat dissipation method used in marine motors, the motor 102 of this invention adopts a liquid-cooled circulating heat dissipation method. Through the efficient heat exchange between the first cooling medium and the heat exchanger 116, it is not limited by the closed cabin environment and can improve the heat dissipation efficiency. At the same time, the temperature difference is monitored in real time by the first temperature sensor 132 and the second temperature sensor 134, and the medium flow rate is dynamically adjusted by the drive component 136, so as to achieve precise control of the heat dissipation of the motor 102.
[0055] This invention dissipates heat from the motor 102 by using a first temperature sensor 132, a second temperature sensor 134, a drive component 136, and a heat exchanger 116. The first and second temperature sensors 132 and 134 detect the temperature difference between the inlet and outlet liquids of the heat exchanger 116, thereby determining the current heat dissipation efficiency and heat load of the motor 102. The drive component 136 dynamically adjusts the flow rate of the first cooling medium based on the temperature difference, ensuring that the motor 102 maintains a suitable temperature under different loads and operating conditions. This achieves precise control of the motor 102's operating temperature, ensuring stable and efficient operation, thus improving the heat dissipation effect and extending the service life of the motor 102. Furthermore, based on the detected temperature difference, when the temperature difference increases, the drive component 136 accelerates the circulation of the first cooling medium, improving heat dissipation efficiency; conversely, when the temperature difference decreases, indicating good heat dissipation, reducing the flow rate of the drive component 136 saves energy.
[0056] Specifically, the heat exchanger 116, drive component 136, first temperature sensor 132, and second temperature sensor 134 can serve as the cooling system for the motor 102. This cooling system not only ensures the stable operation of the motor 102 under a wide range of operating conditions but also reduces energy consumption through intelligent adjustment, extending the overall service life of the motor 102 and the cooling system. Simultaneously, the system has overheat protection; when abnormally high temperatures are detected, corresponding measures can be taken immediately to prevent damage to the motor 102.
[0057] Specifically, the first temperature sensor 132 and the second temperature sensor 134 are used to monitor temperature changes in real time and provide data support for the control system.
[0058] Specifically, the first cooling medium is a coolant that can circulate between the motor 102, the drive component 136 and the heat exchanger 116 and can remove heat from the motor 102.
[0059] Specifically, the drive component 136 can adjust the flow rate of the first cooling medium by regulating its flow rate. The drive component 136 is an electronic water pump that provides circulation power. The electronic water pump is a circulation pump that can provide stable and controllable coolant circulation power, and the flow rate can be adjusted according to actual needs.
[0060] Specifically, based on the monitored temperature difference, the control system automatically adjusts the speed of the electric water pump, thereby changing the flow rate of the coolant. When the temperature difference increases, it indicates that the heat accumulation in the motor 102 is accelerating, so the system increases the flow rate of the electric water pump to accelerate the coolant circulation and improve heat dissipation efficiency; conversely, when the temperature difference decreases, it indicates that the heat dissipation effect is good, and the control system can appropriately reduce the flow rate of the electric water pump to save energy, thus realizing the dynamic adjustment of the flow rate of the first cooling medium.
[0061] Specifically, the heat exchanger 116 is provided with a pipe for the first cooling medium to flow through, allowing the first cooling medium to enter and exit the heat exchanger 116. Furthermore, the heat exchanger 116 contains a second cooling medium, which can exchange heat with the first cooling medium flowing through the pipe within the heat exchanger 116, thereby removing heat from the first cooling medium so that it can continue to flow into the first housing 104 to dissipate heat from the motor 102.
[0062] Specifically, heat exchanger 116 is a liquid heat exchanger that can achieve efficient exchange of heat between motor 102 and external cooling medium (such as river water). A second cooling medium, i.e., external cooling medium (such as river water), flows through heat exchanger 116, and heat exchanger 116 can exchange heat with the first cooling medium through the second cooling medium.
[0063] Specifically, the heat exchanger 116, the drive component 136, and the first housing 104 of the motor 102 form a closed loop for the flow of the first cooling medium. The first cooling medium flows out from the outlet of the hot end of the heat exchanger 116, is pressurized by an electronic water pump, enters the inlet of the first housing 104 of the motor 102, undergoes heat exchange inside the first housing 104 of the motor 102, and then flows out from the outlet of the first housing 104 of the motor 102, returning to the inlet of the hot end of the heat exchanger 116 to complete one cycle. The cold end of the heat exchanger 116 is connected to the external water circulation system 200 through the third liquid inlet 122 and the third liquid outlet 124, respectively, using river water or other similar water as the second cooling medium to remove the heat generated by the motor 102. The liquid heat exchanger is the core component of the cooling system; the hot end of the heat exchanger 116 is cyclically connected to the first cooling medium of the motor 102, and the cold end of the heat exchanger 116 is connected to the external water circulation system 200. Through efficient heat conduction and convection heat transfer, the heat generated by the motor 102 is quickly transferred to river water or other water sources, thereby achieving effective cooling of the motor 102.
[0064] In some embodiments of the present invention, optionally, such as Figure 4 , Figure 5 and Figure 6 As shown, the motor assembly 100 also includes a first conduit 138 and a second conduit 140. (As...) Figure 1 and Figure 2 As shown, the first end of the first pipe 138 is connected to the first liquid inlet 108, and the second end of the first pipe 138 is connected to the second liquid outlet 120; the first end of the second pipe 140 is connected to the first liquid outlet 110, and the second end of the second pipe 140 is connected to the second liquid inlet 118; the driving component 136 is disposed on the first pipe 138.
[0065] In this embodiment, the motor assembly 100 further includes a first pipe 138 and a second pipe 140. A first end of the first pipe 138 is connected to a first liquid inlet 108, and a second end of the first pipe 138 is connected to a second liquid outlet 120, thus arranging the first pipe 138 to provide a flow channel for the first cooling medium flowing from the heat exchanger 116 to the first housing 104. A first end of the second pipe 140 is connected to a first liquid outlet 110, and a second end of the second pipe 140 is connected to a second liquid inlet 118, thus arranging the second pipe 140 to provide a flow channel for the first cooling medium flowing from the first housing 104 to the heat exchanger 116. A drive component 136 is disposed in the first pipe 138 and can directly regulate the flow rate of the first cooling medium, improving regulation efficiency. The first pipe 138 and the second pipe 140 provide channels for the circulating flow of the first cooling medium. Furthermore, by adjusting the arrangement of the first pipe 138 and the second pipe 140, the flow resistance of the first cooling medium can be reduced, and the circulation efficiency can be improved. The drive component 136 is in the first pipe 138, which allows the drive component 136 to quickly adjust the flow rate of the first cooling medium entering the motor 102 and adapt to changes in the thermal load of the motor 102 in a timely manner.
[0066] In some embodiments of the present invention, optionally, such as Figure 1 , Figure 2 and Figure 7 As shown, the motor 102 also includes a first mounting component 112 and a second mounting component 114. The first mounting component 112 and the second mounting component 114 are disposed in the first housing 104.

The first end of the first pipe 138 is connected to the first mounting component 112, and the first end of the second pipe 140 is connected to the second mounting component 114; as shown... Figure 1 , Figure 8 and Figure 9 As shown, the heat exchanger 116 includes a second housing 126, a third mounting component 128, and a fourth mounting component 130.

The second end of the first pipeline 138 is connected to the third mounting component 128, and the second end of the second pipeline 140 is connected to the fourth mounting component 130.
[0067] In this embodiment, the motor 102 further includes a first mounting component 112 and a second mounting component 114. The first mounting component 112 and the second mounting component 114 are disposed on the first housing 104 to achieve installation and fixation of the first mounting component 112 and the second mounting component 114.

The first end of the first pipe 138 is connected to the first mounting component 112, and the first end of the second pipe 140 is connected to the second mounting component 114. By setting the first mounting component 112 and the second mounting component 114, in addition to achieving communication between the first end of the first pipe 138 and the first liquid inlet 108, and the first end of the second pipe 140 and the first liquid outlet 110, the stability of the connection between the first pipe 138 and the second pipe 140 and the first housing 104 can be improved, ensuring the sealing of the connection.
[0068] The heat exchanger 116 includes a second housing 126, a third mounting component 128, and a fourth mounting component 130. The third mounting component 128 and the fourth mounting component 130 are disposed on the second housing 126 to enable the installation and fixation of the third mounting component 128 and the fourth mounting component 130. The third mounting component 128 has a second liquid outlet 120, and the fourth mounting component 130 has a second liquid inlet 118 to achieve the arrangement of the second liquid outlet 120 and the second liquid inlet 118. The second end of the first pipe 138 is connected to the third mounting component 128, and the second end of the second pipe 140 is connected to the fourth mounting component 130. By setting the third mounting component 128 and the fourth mounting component 130, in addition to enabling the second end of the first pipe 138 to communicate with the second liquid outlet 120 and the second end of the second pipe 140 to communicate with the second liquid inlet 118, the stability of the connection between the first pipe 138 and the second pipe 140 and the heat exchanger 116 can be improved, ensuring the sealing of the connection.
[0069] By configuring the first mounting component 112, the second mounting component 114, the third mounting component 128, and the fourth mounting component 130, the reliability and sealing of the connections between the motor 102 and the heat exchanger 116 and the first pipeline 138 are ensured, as are the reliability and sealing of the connections between the motor 102 and the heat exchanger 116 and the second pipeline 140, respectively. This also improves the ease of installation and maintenance. It prevents leakage of the first cooling medium during circulation, ensuring the continuity and effectiveness of the first cooling medium circulation.
[0070] In some embodiments of the present invention, optionally, such as Figure 1 and Figure 2As shown, the first temperature sensor 132 is disposed on the third mounting component 128, and there is a first gap 142 between the first temperature sensor 132 and the second housing 126; the second temperature sensor 134 is disposed on the fourth mounting component 130, and there is a second gap 144 between the second temperature sensor 134 and the second housing 126.
[0071] In this embodiment, a first temperature sensor 132 is disposed on a third mounting component 128, and a first gap 142 is provided between the first temperature sensor 132 and the second housing 126 to facilitate the installation and fixation of the first temperature sensor 132. The first temperature sensor 132 can detect the first temperature of the second outlet 120 at the position of the third mounting component 128. A second temperature sensor 134 is disposed on a fourth mounting component 130, and a second gap 144 is provided between the second temperature sensor 134 and the second housing 126 to facilitate the installation and fixation of the second temperature sensor 134. The second temperature sensor 134 can detect the second temperature of the second inlet 118 at the position of the fourth mounting component 130. By mounting the second temperature sensor 134 and the first temperature sensor 132 on the corresponding fourth mounting component 130 and third mounting component 128, this invention can obtain accurate first and second temperatures, thereby obtaining accurate temperature difference changes. Therefore, by rationally arranging the detection points, the temperature of the first cooling medium entering and exiting the heat exchanger 116 can be obtained directly and accurately, avoiding inaccurate temperature differences caused by detection point deviations. Accurate first and second temperature data can truly reflect the thermal load and heat dissipation efficiency of the motor 102, enabling the drive component 136 to adjust the flow rate of the first cooling medium according to the actual temperature difference, thus preventing the motor 102 from being too hot or too cold.
[0072] Specifically, the first temperature sensor 132 is detachably connected to the third mounting component 128, and the second temperature sensor 134 is detachably connected to the fourth mounting component 130.
[0073] Specifically, the first temperature sensor 132 is connected to the third mounting component 128 by adhesive bonding. The second temperature sensor 134 is connected to the fourth mounting component 130 by adhesive bonding.
[0074] In some embodiments of the present invention, optionally, such as Figure 1 and Figure 2 As shown, the heat exchanger 116 also has a third liquid inlet 122 and a third liquid outlet 124. The second cooling medium enters the heat exchanger 116 through the third liquid inlet 122 and flows out through the third liquid outlet 124. The second cooling medium can exchange heat with the first cooling medium.
[0075] In this embodiment, the heat exchanger 116 also has a third inlet 122 and a third outlet 124 to achieve the arrangement of the third inlet 122 and the third outlet 124. The second cooling medium enters the heat exchanger 116 through the third inlet 122 and flows out through the third outlet 124. When the second cooling medium flows through the heat exchanger 116, it can exchange heat with the first cooling medium. The second cooling medium is an external cooling medium. Through heat exchange with the first cooling medium, it can remove the heat absorbed by the first cooling medium from the motor 102, realizing the transfer and dissipation of heat. By setting the third inlet 122 and the third outlet 124 to circulate the second cooling medium, after the first cooling medium absorbs heat from the motor 102, it exchanges heat with the second cooling medium in the heat exchanger 116. The second cooling medium carries away the heat and discharges it through the third outlet 124, completing the heat dissipation, ensuring that the motor 102 can cool down quickly, maintain stable operation, further reduce energy consumption, and extend the service life of the motor 102.
[0076] Specifically, such as Figure 10 As shown, the external water circulation system 200 includes a drive pump 202, a first control valve 204, a second control valve 206, and a filter component 208. The first control valve 204 and the second control valve 206 are located on either side of the drive pump 202. The first control valve 204 and the second control valve 206 can control whether the second cooling medium flows through the drive pump 202. The drive pump 202 can adjust the flow rate of the second cooling medium, thereby controlling its flow velocity. The second cooling medium can enter the drive pump 202 from the inlet side, then enter the heat exchanger 116 through the third inlet 122, and after heat exchange in the heat exchanger 116, it is discharged through the third outlet 124.
[0077] Specifically, a filter element 208 is provided on the liquid inlet side of the drive pump 202 to prevent impurities from flowing with the second cooling medium and to ensure the smooth flow of the second cooling medium. After flowing through the filter element 208, the second cooling medium flows through the second control valve 206, the drive pump 202, the first control valve 204, and the heat exchanger 116.
[0078] Specifically, the external water circulation system 200 is the ship's cooling system, which uses river water or other similar water to dissipate heat from the ship's components. That is, the second cooling medium is river water or other similar water. By connecting the heat exchanger 116 to the external water circulation system 200, the heat from the heat exchanger 116 can be rapidly transferred to the river water or other similar water, thus achieving effective cooling of the motor 102.
[0079] Specifically, in Figure 10 In this context, E represents open water such as river water or lake water during the ship's navigation, used to supply the second cooling medium. M represents the motor (M) driving pump 202.
[0080] In some embodiments of the present invention, optionally, such as Figure 1 and Figure 3 As shown, the cooling channel 106 is arranged circumferentially along the first housing 104.
[0081] In this embodiment, the cooling channels 106 are arranged circumferentially along the first housing 104. By placing the cooling channels 106 inside the first housing 104, not only can the first cooling medium remove the heat from the motor 102, but the first cooling medium can also be prevented from entering the motor 102, thus preventing the first cooling medium from affecting the internal components of the motor 102. The cooling channels 106 of the motor 102 are arranged circumferentially around the first housing 104, that is, the cooling channels 106 are distributed around the circumference of the first housing 104. This achieves uniform heat dissipation from the motor 102 housing and avoids local overheating from affecting the operation of the motor 102. The cooling channels 106 arranged circumferentially along the first housing 104 allow the first cooling medium to absorb the heat of the motor 102 evenly during flow, ensuring a uniform overall temperature of the motor 102; at the same time, the cooling channels 106 arranged circumferentially along the first housing 104 reduce the flow resistance of the first cooling medium and improve circulation efficiency.
[0082] Specifically, in Figure 1 In the diagram, A represents the circumferential direction of the first housing 104.
[0083] In some embodiments of the present invention, optionally, such as Figure 3 As shown, there are multiple cooling channels 106, which are arranged along the axial direction of the motor 102 and are interconnected.
[0084] In this embodiment, there are multiple cooling channels 106. These multiple cooling channels 106 increase the heat dissipation area of the motor 102, thereby improving the heat dissipation efficiency of the motor 102. The multiple cooling channels 106 are arranged along the axial direction of the motor 102 and are interconnected. This arrangement expands the contact area between the first cooling medium and the first housing 104, ensuring that all positions of the motor 102 can be cooled along its axial direction. The interconnection between the multiple cooling channels 106 ensures smooth flow of the first cooling medium, preventing heat accumulation in localized areas and further improving the heat dissipation efficiency of the cooling system. This allows the motor 102 to maintain a uniform temperature even under high load and long-term operation, reducing the energy consumption of the motor 102 and extending its service life.
[0085] Specifically, in Figure 3 In the diagram, B represents the axial direction of motor 102.
[0086] In some embodiments of the present invention, optionally, such as Figure 8 and Figure 11 As shown, the heat exchanger 116 is arranged radially along the motor 102 on the outside of the first housing 104.
[0087] In this embodiment, the heat exchanger 116 is arranged radially to the outside of the first housing 104 along the motor 102, that is, the heat exchanger 116 is installed outside the first housing 104 along the radial direction of the motor 102 and is arranged adjacent to the motor 102 housing. The way the heat exchanger 116 is connected to the motor 102 shortens the distance between the heat exchanger 116 and the motor 102, reduces the length of the connecting pipes, and lowers the flow resistance and heat loss of the first cooling medium. Furthermore, the compact installation of the heat exchanger 116 and the motor 102 reduces the installation space of the motor assembly 100, avoiding the occupation of excessive space within the ship's cabin.
[0088] Specifically, the heat exchanger 116 is detachably connected to the motor 102.
[0089] Specifically, the heat exchanger 116 is connected to the motor 102 by bolts.
[0090] Specifically, in Figure 8 and Figure 11 In the figure, C represents the radial direction of motor 102.
[0091] In some embodiments of the present invention, optionally, such as Figure 8 As shown, the first liquid inlet 108 and the first liquid outlet 110 are arranged radially on the outside of the first housing 104 along the motor 102, and the first liquid outlet 110 is higher than the first liquid inlet 108 along the height direction of the motor 102.
[0092] In this embodiment, the first liquid inlet 108 and the first liquid outlet 110 are arranged radially on the outside of the first housing 104 along the motor 102, and the first liquid outlet 110 is higher than the first liquid inlet 108 along the height direction of the motor 102, so as to realize the arrangement of the first liquid inlet 108 and the first liquid outlet 110. By adjusting the installation position of the first liquid inlet 108 and the first liquid outlet 110, when the first cooling medium is added to the cooling channel 106, since the position of the first liquid inlet 108 is relatively high, as the first cooling medium is injected, the gas in the cooling channel 106 can be gradually and completely discharged to the outside, avoiding the presence of gas in the cooling channel 106 after the first cooling medium is injected into the cooling channel 106, avoiding the impact on the heat dissipation effect of the motor 102, improving the circulation rate of the first cooling medium, and also improving the heat dissipation efficiency.
[0093] Specifically, in Figure 8 In the diagram, D represents the height direction of motor 102.
[0094] Specifically, motor 102 is a permanent magnet synchronous motor.

[0097] Specifically, the motor assembly 100 is installed on the ship, and the motor 102 can drive the propeller to rotate when it is running, thereby driving the ship to move.
[0098] Specifically, the motor assembly 100, equipped with intelligent temperature control and efficient heat dissipation, ensures that the ship can provide stable power under different navigation conditions, avoids power interruption or failure caused by overheating of the motor 102, and improves the operational reliability of the ship.
