[0003] The existing stator mainly has the following drawbacks during practical use: the stator is formed by stacking multiple silicon steel sheets. During the operation of the electric motor, the silicon steel sheets are prone to heat due to electromagnetic action, and due to the stacking of the silicon steel sheets, the heat is difficult to dissipate, resulting in heat accumulation and easily burning out the circuits of the electric motor. Therefore, there is an urgent need for a stator winding module with high heat dissipation efficiency. Summary of the Utility Model

Specific embodiments

[0024] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0025] Some embodiments of the present utility model will be described below with reference to the accompanying drawings. Embodiment 1

[0026] Combined with Figure 1-6 As shown, this embodiment provides a stator winding module, including: a main body mechanism 100.

[0027] Among them, the main body mechanism 100 includes a plurality of silicon steel sheets 110 arranged in a group and multiple groups of mutually stacked silicon steel sheets 110, a heat dissipation plate 120 arranged between the opposite groups of silicon steel sheets 110, an I-shaped fixing rod 130 arranged in an annular array and passing through the groups of silicon steel sheets 110 and the heat dissipation plate 120, and a cooling member 140 passing through the silicon steel sheets 110 and the heat dissipation plate 120.

[0028] A plurality of silicon steel sheets 110 are arranged in a group, and the plurality of silicon steel sheets 110 are stacked on each other, and the heat dissipation plate 120 is arranged between adjacent groups of silicon steel sheets 110. Through this setting, the silicon steel sheets 110 can be dispersed without affecting the winding, thereby avoiding the problem of heat accumulation caused by excessive stacking of the silicon steel sheets 110.

[0029] A plurality of T-shaped protrusions 111 are integrally fixed in an annular array on the inner side of the silicon steel sheet 110 for winding.

[0030] The heat sink 120 separates the silicon steel sheet 110 and is made of a heat-conducting material, so as to dissipate heat for the silicon steel sheet 110. The heat sink 120 includes symmetrically arranged heat-conducting plates 121 and support plates 122 arranged in an annular array between the opposite heat-conducting plates 121 and fixedly connected to the heat-conducting plates 121 on both sides. The heat-conducting plates 121 are closely attached to the silicon steel sheet 110, so that the heat on the silicon steel sheet 110 is conveniently transferred to the heat-conducting plates 121. Meanwhile, the arrangement of the support plates 122 can form a cavity between the opposite heat-conducting plates 121, so that air can flow through and take away the heat on the heat-conducting plates 121, thereby dissipating heat for the silicon steel sheet 110.

[0031] A first waist-shaped hole 112 is opened in a circular array on the silicon steel sheet 110, and a second waist-shaped hole 1211 is arranged in a circular array on the heat conducting plate 121. Through the arrangement of the first waist-shaped hole 112 and the second waist-shaped hole 1211, an air duct can be formed in the silicon steel sheet 110, which facilitates the air to pass through and take away the heat on the silicon steel sheet 110, thereby further improving the heat dissipation performance of the stator.

[0032] The I-shaped fixing rod 130 is used to fix and connect multiple groups of silicon steel sheets 110 and heat sinks 120 together to form a whole, namely a stator. A plurality of first circular holes 113 are opened in a circular array on the silicon steel sheet 110, and a second circular hole 1212 is opened in a circular array on the top of the heat conducting plate 121. The I-shaped fixing rod 130 passes through the first circular hole 113 and the second circular hole 1212 to connect the heat conducting plate 121 and the silicon steel sheet 110 together, while ensuring that the first waist-shaped hole 112 on the silicon steel sheet 110 is aligned with the second waist-shaped hole 1211 on the heat conducting plate 121.

[0033] The cooling member 140 is used to dissipate heat for the silicon steel sheet 110, and includes an upper annular tube 141 arranged above the silicon steel sheet 110, a lower annular tube 142 arranged below the silicon steel sheet 110, and a waist-shaped tube 143 passing through the silicon steel sheet 110 group and the heat dissipation plate 120. The upper annular tube 141, the lower annular tube 142, and the waist-shaped tube 143 are all made of heat-conducting materials to facilitate heat transfer. The waist-shaped tube 143 passes through the first waist-shaped hole 112 and the second waist-shaped hole 1211, and is closely attached to the inner walls of the first waist-shaped hole 112 and the second waist-shaped hole 1211, so that the heat on the silicon steel sheet 110 and the heat conducting plate 121 is transferred to the waist-shaped tube 143, and heat is exchanged with the cooling water in the waist-shaped tube 143, thereby taking away the heat on the silicon steel sheet 110 and the heat conducting plate 121, and cooling the silicon steel sheet 110.

[0034] A water inlet 1411 is installed at the top of the upper annular tube 141 and is connected to the inner cavity of the upper annular tube 141 for delivering cooling water into the upper annular tube 141. A water outlet 1421 is provided on the lower annular tube 142 and is connected to the inner cavity of the lower annular tube 142 for delivering the cooling water after absorbing heat to form a circulation.

[0035] Working principle and usage process of the present utility model: During use, due to the arrangement of multiple sets of silicon steel sheets 110 sandwiching the heat dissipation plate 120, heat accumulation on the silicon steel sheets 110 can be avoided. The heat on the silicon steel sheet groups on both sides of the heat dissipation plate 120 is transferred to the heat conduction plate 121. At this time, when air passes through the space between the opposing heat conduction plates 121, it can drive the heat on the heat conduction plate 121 to dissipate the heat of the silicon steel sheets 110. Meanwhile, the cooling water enters the upper annular pipe 141 through the water inlet 1411 and enters the waist-shaped pipe 143 from the upper annular pipe 141. The cooling water flows in the waist-shaped pipe 143 and exchanges heat with the heat on the silicon steel sheets 110 to reduce the temperature of the silicon steel sheets 110 and dissipate the heat of the silicon steel sheets 110. The cooling water after absorbing heat enters the lower annular pipe 142 and is sent out through the water outlet 1421 to form a cycle.

[0036] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
