[0002] Traveling by car is one of the main forms of modern transportation. Cars are divided into different types according to different driving modes. Cars driven by motors are one of them, which are called new energy vehicles. In the application process, in order to ensure the heat dissipation of the automobile motor, a circulating water channel is generally set on its shell to achieve water cooling;

[0003] When the existing circulating water channel structure of the motor casing of new energy vehicles is in use, it generally uses a whole water channel to implement the heat dissipation task. However, this method will result in the part closer to the water inlet having a better heat dissipation effect during application, while the part closer to the water outlet has already absorbed part of the heat due to the coolant, resulting in limited heat dissipation effect, making the overall heat dissipation uniform, which can easily cause aging of motor components and affect their service life.

[0009] As a further solution of the utility model: strip-shaped air inlets are evenly provided at both ends of the motor outer protective housing, and heat dissipation exhaust ports are evenly provided at one end of the motor outer protective housing away from the output shaft.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 7As shown, the utility model is a circulating water channel structure of a motor housing of a new energy vehicle, comprising a motor outer protective compartment 1, a motor body 4 is arranged inside the motor outer protective compartment 1, an output end of the motor body 4 is connected to an output shaft 5, and the output shaft 5 passes through the motor outer protective compartment 1, a coolant discharge transfer part 7 is installed on the side of the motor body 4 away from the output shaft 5, and a coolant inlet transfer part 9 is installed on the side of the motor body 4 close to the output shaft 5, four groups of heat absorbing channel pipes 11 are installed around the outer wall of the motor body 4, one end of the heat absorbing channel pipe 11 is connected to the coolant discharge transfer part 7, and the other end of the heat absorbing channel pipe 11 is connected to the coolant discharge transfer part 7. Enter the transfer part 9 for communication, support connectors 6 are installed around the outer wall of the motor body 4, the support connectors 6 are fixedly connected to the motor outer casing 1, and the support connectors 6 are located in the gap of the heat absorption pipe fittings 11, the thickness of the support connectors 6 is greater than the thickness of the pipe body of the heat absorption pipe fittings 11, so that there is a gap between the motor body 4 and the motor outer casing 1, and air can flow through it, the wall thickness of the motor body 4 is relatively thin, only acting on the internal rotor stator part of the protective installation, and is made of materials with better heat dissipation effect, and further, a dust-proof hole can be opened on the motor body 4 for heat dissipation treatment;

[0029] like Figure 5 and Figure 7 As shown, the coolant discharge transfer member 7 is connected to a first extension pipe 8 on the side away from the motor body 4, and the first extension pipe 8 penetrates the motor outer casing 1, and the coolant inlet transfer member 9 is connected to a second extension pipe 10 on the side away from the motor body 4, and the second extension pipe 10 penetrates the motor outer casing 1, the first extension pipe 8 and the second extension pipe 10 can be fixedly connected to the motor outer casing 1, and connected to the water pump and the coolant cooling device through the first extension pipe 8 and the second extension pipe 10 to form a circulating water circuit, and the coolant discharge transfer member 7 and the coolant inlet transfer member 9 can be in the form of an inner hollow box;

[0030] like Figure 2 As shown, the heat absorbing pipe 11 is wavy, and the cross-sectional shape of the heat absorbing pipe 11 is square, so as to ensure the contact area between the heat absorbing pipe 11 and the corresponding surface of the motor body 4, thereby ensuring the heat absorption effect;

[0031] like Figure 1 , Figure 3 and Figure 4As shown, the motor body 4 is provided with an air cooling mechanism for driving external air flow into and through the inside of the motor outer casing 1, the air cooling mechanism includes a drive motor 12, the drive motor 12 is installed on the side of the motor body 4 away from the output shaft 5, the output end of the drive motor 12 is connected to a rotating shaft 13, and a fan 14 is installed at the end of the rotating shaft 13 away from the drive motor 12, both ends of the motor outer casing 1 are evenly provided with strip-shaped air inlets 2, and the end of the motor outer casing 1 away from the output shaft 5 is evenly provided with heat dissipation exhaust ports 3. During use, when the fan 14 rotates, it can drive external air to enter through the strip air inlet 2 and be discharged through the heat dissipation exhaust port 3. In this process, the air can absorb the heat in the motor outer casing 1 and discharge it, thereby implementing an air cooling effect.

[0032] The working principle of the utility model is as follows: the first extension tube 8 and the second extension tube 10 are connected with the water pump and the coolant cooling device. During use, the water pump and the coolant cooling device are turned on, and the water pump drives the coolant from the second extension tube 10 into the coolant entering the transfer part 9, and further enters the four groups of heat absorbing channel pipes 11 at the same time, and then flows to the coolant discharge transfer part 7 for concentration, and further circulates to the coolant cooling device, and the above process is repeated continuously. During this process, the coolant can independently absorb heat for different parts of the motor body 4 when in the four groups of heat absorbing channel pipes 11, so as to achieve the heat dissipation task, and the heat dissipation effect is uniform. At the same time, during this process, since the coolant discharge transfer part 7 and the coolant entry transfer part 9 are respectively located on one side of the motor body 4, it can be avoided that the coolant with higher heat in the coolant discharge transfer part 7 affects the coolant with lower heat in the coolant entry transfer part 9;

[0033] During the above process, the drive motor 12 is turned on at the same time, and the drive motor 12 drives the fan 14 to rotate forward through the rotating shaft 13, thereby driving the external air to continuously enter the motor outer protective compartment 1 through the strip air inlet 2 and then be discharged through the heat dissipation exhaust port 3, thereby further implementing an air-cooling cooling effect on the motor body 4. At the same time, in this process, since the coolant enters the transfer part 9 close to the strip air inlet 2, the air does not absorb heat from the motor body 4 at this time, and the heat is relatively low, thereby avoiding the heat increase of the coolant entering the transfer part 9 and affecting its subsequent heat absorption effect.

[0034] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
