[0002] The motor mainly consists of a stator and a rotor. The motor generates heat during operation. The motor is easily damaged if it runs in a high temperature environment for a long time. Therefore, the stator needs to be cooled. The general heat dissipation structure discharges the heat inside the stator through the exhaust holes, but it allows external dust to enter the stator, so there are certain shortcomings.

[0003] For example, a high heat dissipation stator structure with publication number CN217486259U has a large position gap between the upper winding plug and the lower winding plug, which has an excellent heat dissipation effect on the inside of the stator winding. At the same time, the arrangement of multiple heat dissipation holes on the stator body further accelerates the heat dissipation speed of the stator winding, ensures efficient heat dissipation performance, and improves the service life of the motor. The inner walls of the two ends of the stator body are embedded with an upper pressure ring plate and a lower pressure ring plate through a plug-in group, which is easy to install and disassemble, and is convenient for subsequent disassembly and replacement of the stator winding.

[0004] The above-mentioned prior art has the following technical problems: the heat dissipation holes arranged in the existing stator have relatively large openings, and the magnetic field generated when the motor is working will attract dust, so that external dust can easily enter the inside of the stator through the heat dissipation holes during use.

[0005] Therefore, we propose a starter stator assembly with high heat dissipation in order to solve the above-mentioned problems. Utility Model Content

[0007] To achieve the above object, the utility model provides the following technical solution: a high heat dissipation starter stator assembly, comprising a shell, the inner wall of the shell is provided with a mounting groove, the inside of the shell is provided with a receiving groove, and the outer wall of the shell is provided with an air outlet;

[0008] Also includes:

[0009] The inner wall of the stator core is provided with a first air hole, the outer wall of the first air hole is provided with a second air hole, and the outer wall of the stator core is wound with a coil;

[0010] A cooling pipe is fixedly installed in the cavity opened by the heat conductive block, and the head end of the cooling pipe is connected with a liquid infusion pipe, the tail end of the cooling pipe is connected with a liquid outlet pipe, and the side wall of the heat conductive block is connected with a connecting pipe.

[0011] Preferably, four groups of the mounting grooves are arranged in an array about the inner wall of the housing, and the width of the tail end of the stator core is smaller than the width of the mounting grooves.

[0012] Preferably, a threaded hole is provided at the tail end of the stator core, and the stator core is installed in the installation groove through bolts and the threaded hole provided in the outer wall of the shell.

[0013] Preferably, the heat conductive block is arranged in an "I" shape, and the heat conductive block is fixedly installed inside the accommodating groove, and the material of the heat conductive block is silicone.

[0014] Preferably, the first air hole is connected to the tail end of the second air hole, and the second air hole is composed of two groups of small exhaust holes, and the positions of the second air hole and the air outlet hole correspond to each other.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the high heat dissipation starter stator assembly, by improving the design of the heat dissipation holes, prevents external dust from entering the stator while dissipating the heat of the stator, and further improves the heat dissipation effect of the stator through the heat dissipation module. The specific contents are as follows:

[0018] 1. A stator core is provided, and the stator core is installed in a mounting groove provided in the housing by bolts.

[0030] 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 in 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.

[0031] Example 1: Please refer to Figure 1-Figure 2 and Figure 4 The utility model provides the following technical solutions. The heat dissipation holes arranged inside the existing motor are relatively large. When dissipating heat, it is easy for external dust to enter the motor through the heat dissipation holes. In order to solve this technical problem, the present embodiment discloses the following technical contents: a high heat dissipation starter stator assembly, comprising a housing 1, an inner wall of the housing 1 is provided with a mounting groove 101, an inner wall of the housing 1 is provided with a receiving groove 102, and an outer wall of the housing 1 is provided with an air outlet 9;

[0032] The second air holes 202 are composed of two groups of small apertures, and the first air holes 201 opened inside the stator core 2 are arranged in a curved shape, so that while the heat inside the motor is transferred out through the air outlet 9, dust outside the motor will not easily enter the inside of the motor.

[0033] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above-mentioned embodiment 1. The improved heat dissipation holes can prevent external dust from entering the motor while ensuring the internal heat dissipation of the motor. Figure 1-Figure 2 and Figure 4 As shown, the inner wall of the stator core 2 is provided with a first air hole 201, and the outer wall of the first air hole 201 is provided with a second air hole 202, and the outer wall of the stator core 2 is wound and connected with a coil 3; four groups of mounting grooves 101 are provided in an array with respect to the inner wall of the housing 1, and the width of the tail end of the stator core 2 is smaller than the width of the mounting groove 101. A threaded hole is provided at the tail end of the stator core 2, and the stator core 2 is installed in the mounting groove 101 through bolts and threaded holes provided on the outer wall of the housing 1. The first air hole 201 is connected to the tail end of the second air hole 202, and the second air hole 202 is composed of two groups of small exhaust holes, and the second air hole 202 corresponds to the position of the air outlet hole 9. The material of the stator core 2 is silicon steel, and the stator core 2 is arranged in a "T" shape.

[0034] The stator core 2 is installed in the installation groove 101 opened in the shell 1 by bolts. When in use, a large amount of heat is generated inside the motor, and then the heat inside the motor is conducted out through the first air hole 201 and the second air hole 202 opened in the stator core 2 through the air outlet 9. Since the electromagnetic force generated by the internal operation of the motor will attract dust, the second air hole 202 is composed of two groups of small apertures, and the first air hole 201 opened in the stator core 2 is arranged in a curved shape. While the heat inside the motor is transferred out through the air outlet 9, the dust outside the motor will not easily enter the motor, thereby dissipating the heat of the components inside the motor and protecting it.

[0035] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned embodiments 1 and 2. Since the efficiency of heat dissipation through the heat dissipation holes of the internal heat generated by the motor will be reduced when the motor works for a long time, the heat dissipation component is used to further dissipate the heat evenly inside the motor, such as Figure 1-Figure 3 and Figure 5-Figure 6 As shown, a cooling tube 7 is fixedly installed in the cavity opened by the heat-conducting block 4, and the head end of the cooling tube 7 is connected with the infusion tube 5, and the tail end of the cooling tube 7 is connected with the outlet tube 6, and the side wall of the heat-conducting block 4 is connected with the connecting tube 8. The heat-conducting block 4 is arranged in the shape of an "I", and the heat-conducting block 4 is fixedly installed inside the accommodating groove 102, and the material of the heat-conducting block 4 is silicone. The cooling tube 7 is arranged in an "S" direction on the inner wall of the cavity opened by the heat-conducting block 4, and the connecting tube 8 is connected with the cooling tube 7, and the cooling tube 7 and the connecting tube 8 are both silicone tubes.

[0036] The heat-conducting block 4 is a silicone part in the shape of an "I". When the motor is in use, a large amount of heat will be generated on the inner wall of the motor, and the heat will be transferred to the outside through the heat-conducting block 4 made of silicone that is easy to absorb heat, thereby further playing a role in cooling the motor. When there is too much heat inside the motor, the cooling medium is input into the cooling tube 7 inside the head end of the heat-conducting block 4 through the infusion tube 5, and the cooling tube 7 in the "S" direction strengthens the absorption of the heat generated inside the motor, thereby playing a role in further absorbing the heat inside the motor. A total of four groups of heat-conducting blocks 4 and cooling tubes 7 are arranged in the motor. At the same time, the cooling tubes 7 in each group of adjacent heat-conducting blocks 4 are connected through connecting tubes 8. After the cooling is input into the first group of cooling tubes 7, it is dispersed to the cooling tubes 7 at the head ends of other heat-conducting blocks 4 through the connecting tubes 8, so that the heat inside the motor can be evenly absorbed.
