However, this utility model has the following problems: first, the air-cooled heat dissipation noise is large, the heat dissipation effect is easily affected by dust, and a large space is required.

[0022] The technical solutions in the embodiments of the present utility model are clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, the utility model provides an auxiliary structure of a car driving steering system, including a new energy motor 1, which is a steering motor in a new energy car. The lower end of the new energy motor 1 is provided with a base plate 2 for installing the new energy motor 1, and the periphery of the new energy motor 1 is provided with an auxiliary heat dissipation structure 3 for water-cooling the new energy motor 1, which is noiseless, occupies a small space, and has a good heat dissipation effect. The auxiliary heat dissipation structure 3 includes a heat dissipation shell 31, and the surface of the heat dissipation shell 31 is provided with a heat dissipation groove 32 for installing a heat dissipation plate 12, and a water-cooling pipe 312 is evenly distributed between the heat dissipation shell 31 and the new energy motor 1. A water-cooling inner pipe 33 is provided in the water-cooling pipe 312, and a diverter plate 313 is evenly distributed on the surface of the water-cooling inner pipe 33. A gap 34 is provided between the diverter plate 313 and the water-cooling pipe 312. When the coolant enters the water-cooling pipe 312, it is directly flushed on the water-cooling inner pipe 33, thereby being diverted by the diverter plate 313. The water flow is reduced, the flow velocity is reduced, and the flow time is prolonged, thereby increasing the cooling effect.

[0025] Further, if Figure 2As shown, the water-cooling pipe 312 is provided with an arc-shaped groove 35 on the side close to the new energy motor 1, and a heat conducting plate 36 is provided in the arc-shaped groove 35. The heat conducting plate 36 is made of a metal shell, a capillary structure and an actuating fluid through annealing, vacuuming and sealing processes. The end of the heat conducting plate 36 away from the arc-shaped groove 35 abuts the new energy motor 1, connecting the water-cooling pipe 312 and the new energy motor 1 together. When the new energy motor 1 generates heat during operation, the heat conducting plate 36 absorbs the heat and conducts the heat to the water-cooling pipe 312. The coolant in the water-cooling pipe 312 exchanges heat with the heat conducting plate 36, thereby achieving a good heat dissipation result.

[0026] Furthermore, diversion pipes 37 are symmetrically provided at the upper and lower ends of the water-cooling pipe 312. The lower end of the diversion pipe 37 is connected to the return pipe 38, and the upper end of the diversion pipe 37 is connected to the annular pipe 39. The coolant in the annular pipe 39 flows into the water-cooling pipe 312 through the diversion pipe 37, and then the coolant in the water-cooling pipe 37 flows into the return pipe 38 through the diversion pipe 37.

[0027] Further, if Figure 1 As shown, a water outlet pipe 310 is provided at the rear end of the return pipe 38. The end of the water outlet pipe 310 away from the return pipe 38 passes through the right surface of the heat dissipation shell 31 and protrudes vertically on its surface. The water outlet pipe 310 is connected to the water cooling circulation equipment, and the cooling water in the return pipe 38 flows out through the water outlet pipe 310.

[0028] Furthermore, a water inlet pipe 311 is provided at the upper end of the annular tube 39 , and the upper end of the water inlet pipe 311 passes through the upper surface of the heat dissipation shell 31 and protrudes vertically from its surface. The water inlet pipe 311 is connected to the water cooling circulation equipment, and the coolant in the water inlet pipe 311 flows into the annular tube 39 .

[0029] Further, if Figure 1 As shown, a connecting pipe 11 is provided at the upper end of the new energy motor 1, and the end of the connecting pipe 11 away from the new energy motor 1 protrudes vertically on the right surface of the heat dissipation shell 31, and is connected to the external steering assembly through the connecting pipe 11, so that the new energy motor 1 transfers kinetic energy to the external steering assembly. A heat dissipation plate 12 is provided in the heat dissipation groove 32, and heat dissipation holes are evenly distributed on the surface of the heat dissipation plate 12. The remaining heat in the heat dissipation shell 31 after water cooling is dissipated to the outside through the heat dissipation plate 12, thereby ensuring that the temperature around the new energy motor 1 is kept at a low temperature.

[0030] Working process: first, the coolant enters the annular tube 39 through the water inlet pipe 311; further, the coolant in the annular tube 39 flows into the water-cooling tube 312 through the diverter pipe 37 at the upper end; further, when the coolant enters the water-cooling tube 312, it is directly flushed on the water-cooling inner tube 33, and is thereby diverted by the diverter plate 313. The water flow is reduced, resulting in a reduced flow rate and a longer flow time, thereby increasing the cooling effect; further, the coolant in the water-cooling tube 312 enters the return pipe 38 through the diverter pipe 37 at the lower end, and returns to the water-cooling circulation equipment through the outlet pipe 310.
