Description

Technical Field

[0001] This utility model relates to the field of motor heat dissipation technology, specifically to an integrated structure of cooling channels and housing. Background Technology

[0002] Currently, motor heat dissipation is a key factor affecting motor performance. Motor heat dissipation is influenced by various factors, among which the heat dissipation method is a crucial one. Motors generally use gas or liquid as the cooling medium to dissipate heat. The cooling medium flows through the cooling channels, carrying away heat and thus reducing the motor temperature, ensuring stable operation and extending the motor's lifespan.

[0003] The patent publication number is CN116937869A, which discloses a motor housing structure with good heat dissipation performance. The structure includes a motor housing and a heat dissipation and sound insulation structure. The heat dissipation and sound insulation structure includes a protective shell, which is sleeved and installed on the motor housing. The protective shell has a heat dissipation and cooling component embedded inside it to cool the motor housing. The heat dissipation and cooling component includes multiple annular tubes. The top and bottom of the annular tubes are respectively provided with an upper shunt tube and a lower manifold.

[0004] The above-mentioned patented technologies still have certain shortcomings. Although they can dissipate heat from the motor housing, they achieve this by adding a scattering structure to the protective shell of the motor housing, which increases the weight of the motor housing and is not conducive to the lightweight development of motors. Utility Model Content

[0005] The main technical problem to be solved by this utility model is to provide an integrated structure of cooling channel and housing. This structure integrates the cooling channel and motor housing into one piece, which can greatly improve the heat dissipation effect of the motor housing and facilitate use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] The cooling channel and the housing are integrated into a structure including a motor housing. The motor housing has cooling channels distributed along the axial direction inside. The cooling channels include several short U-shaped channels and several long U-shaped channels. Each short U-shaped channel and each long U-shaped channel are connected to each other and arranged at intervals to form a closed and tortuous channel. The cooling channels are also connected to an inlet pipe for conveying coolant and an outlet pipe for discharging coolant.

[0008] The following are further optimizations of the above technical solution by this utility model:

[0009] The cooling channel is embedded inside the motor housing and is integrally formed with the motor housing.

[0010] This design improves the tightness between the cooling channels and the motor housing, thereby increasing the weight of the motor housing while preventing coolant from flowing out and contaminating or corroding it.

[0011] Further optimization: The outer side of the motor housing is provided with a protrusion for placing objects.

[0012] This design allows the protrusions on the motor housing to be snapped onto the storage device for easy use.

[0013] This utility model adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. It can make the coolant fully spread inside the motor housing, thereby effectively removing heat and improving the cooling efficiency of the motor. The cooling channel is integrally formed with the motor housing, which reduces the number of parts, reduces processing and assembly steps, and lowers production costs.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] like Figure 1-5 As shown: The cooling channel and the outer shell are integrated into a structure, including a motor housing 1. The motor housing 1 has a cooling channel 2 distributed along the axial direction inside. The cooling channel 2 includes a number of U-shaped short channels 21 and a number of U-shaped long channels 22. Each U-shaped short channel 21 and U-shaped long channel 22 are connected to each other and arranged at intervals to form a closed and tortuous channel. The cooling channel 2 is also connected to an inlet pipe 23 for conveying coolant and an outlet pipe 24 for outflowing coolant.

[0022] Coolant is provided in the cooling channel 2.

[0023] The cooling channel 2 is embedded inside the motor housing 1 and is integrally formed with the motor housing 1.

[0024] This design improves the tightness of the connection between the cooling channel 2 and the motor housing 1, preventing coolant from leaking out of the cooling channel 2 and corroding the motor housing 1.

[0025] The outer side of the motor housing 1 is provided with a protrusion 3 for placing objects.

[0026] In use, the coolant is first poured into the cooling channel 2 through the inlet pipe 23. Since the cooling channel 2 is composed of several short U-shaped channels 21 and several long U-shaped channels 22, the coolant can be fully distributed inside the motor housing 1, thereby effectively removing heat and improving the cooling efficiency of the motor. The cooling channel 2 is integrally formed with the motor housing 1, which reduces the number of parts, reduces processing and assembly steps, and reduces production costs.

[0027] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
