Description

Technical Field

[0001] This utility model relates to the field of motor component technology, specifically a lightweight and efficient heat dissipation stator. Background Technology

[0002] In the field of racing simulation, the motor, as a core power component, directly affects the overall performance of the race car. The stator, as a key component of the motor, has crucial heat dissipation performance. A search revealed Chinese patent publication number CN222721280U, which discloses a high-efficiency heat dissipation motor stator structure, including a stator core. A shell is movably fitted onto the outer circular wall of the stator core, a heat-conducting layer is fixedly fitted onto the outer circular wall of the stator core, and a silicone insulating layer is fixedly fitted onto the outer circular wall of the heat-conducting layer.

[0003] While the above-mentioned technical solution can cool the coolant in real time and prevent the coolant from overheating due to insufficient heat dissipation, eliminating the need to replace the coolant and reducing manual operation, during use, the coolant flows through the straight guide pipe and connecting cover, which can easily create a flow blind zone at the gap between the heat sink and the stator core, leading to local heat accumulation. Furthermore, as the temperature increases, the coolant temperature also increases, and relying solely on air cooling for heat dissipation has limited effectiveness. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a lightweight and efficient heat dissipation stator, comprising a stator body and a shell located outside the stator body, wherein a heat dissipation mechanism is installed between the outer side of the stator body and the shell. The heat dissipation mechanism includes a heat dissipation sleeve with a spiral groove on the inner wall. A spiral heat exchange tube is fixedly connected inside the spiral groove. A coolant storage tank is fixedly installed on the top of the outer shell. A circulation pump is fixedly installed on one side of the coolant storage tank. The two ends of the spiral heat exchange tube are fixedly connected to the output end of the circulation pump and the inside of the coolant storage tank, respectively.

[0006] Preferably, the stator body includes an outer ring, and the inner wall of the outer ring is fixedly connected with a plurality of winding posts in a ring array to facilitate coil winding.

[0007] Preferably, a heat-conducting layer is fixedly sleeved on the outer surface of the stator body, and an insulating layer is fixedly connected between the heat-conducting layer and the heat dissipation sleeve to facilitate heat conduction and insulation.

[0008] Preferably, the top of the coolant storage tank is fixedly connected with multiple U-shaped heat dissipation plates, both ends of which extend into the interior of the coolant storage tank. A cooling fan is fixedly installed on the top of the U-shaped heat dissipation plate to facilitate the cooling of the coolant.

[0009] Preferably, the outer surface of the coolant storage tank has multiple openings on both sides that match the two ends of the U-shaped heat sink, facilitating the installation of the U-shaped heat sink.

[0010] Preferably, a heat-conducting plate is embedded and fixedly installed on the top of the coolant storage tank, and a semiconductor refrigeration chip is fixedly installed on the top of the heat-conducting plate. Thermal grease is provided between the cooling end of the semiconductor refrigeration chip and the heat-conducting plate, which can perform semiconductor cooling on the coolant, thereby improving the heat dissipation effect.

It has the following beneficial effects: This lightweight and efficient heat dissipation stator has a stable structure and light weight, which can reduce the weight of the motor.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: like Figure 1 and Figure 2 As shown, a lightweight and efficient heat dissipation stator includes a stator body 1 and a housing 2 located outside the stator body 1. The stator body 1 includes an outer ring 11, and a plurality of winding posts 12 are fixedly connected to the inner wall of the outer ring 11 in a ring array.

[0016] The winding post 12 facilitates coil winding. In this technical solution, the stator body 1 uses a new type of high-strength, lightweight material, such as a composite material of carbon fiber reinforced composite and silicon steel. This material significantly reduces the weight of the core while ensuring the magnetic permeability of the core.

[0017] Through special composite processes, such as fiber winding directional composite or lamination composite, two materials can form a stable interface bond. For example, embedding oriented carbon fiber bundles between silicon steel sheets can both maintain the magnetic circuit conductivity required by the silicon steel sheets and enhance the mechanical strength of the overall structure through the carbon fibers, preventing the iron core from deforming or cracking under the centrifugal force of high-speed operation.

[0018] like Figures 1 to 6 As shown, a heat dissipation mechanism 3 is installed between the outer side of the stator body 1 and the outer shell 2. The heat dissipation mechanism 3 includes a heat dissipation sleeve 31. A spiral groove 32 is opened on the inner wall of the heat dissipation sleeve 31. A spiral heat exchange tube 33 is fixedly connected inside the spiral groove 32. A coolant storage tank 34 is fixedly installed on the top of the outer shell 2. A circulation pump 35 is fixedly installed on one side of the coolant storage tank 34. The two ends of the spiral heat exchange tube 33 are fixedly connected to the output end of the circulation pump 35 and the inside of the coolant storage tank 34, respectively.

[0019] The operation of the circulating pump 35 can drive the coolant to circulate. The spiral heat exchange tube 33 can increase the heat dissipation area of ​​the coolant on the stator, thereby improving the heat dissipation effect.

[0020] Multiple U-shaped heat sinks 36 are fixedly connected to the top of the coolant storage tank 34. Both ends of the U-shaped heat sinks 36 extend into the interior of the coolant storage tank 34, and cooling fans 37 are fixedly installed on the top of the U-shaped heat sinks 36. Multiple openings that mate with the ends of the U-shaped heat sinks 36 are provided on both sides of the outer surface of the coolant storage tank 34.

[0021] The operation of the cooling fan 37 can drive airflow, which, together with the U-shaped heat sink 36, can cool the coolant and prevent it from affecting the heat dissipation effect.

[0022] A heat-conducting plate 38 is embedded and fixedly installed on the top of the coolant storage tank 34. A thermoelectric cooler 39 is fixedly installed on the top of the heat-conducting plate 38. Thermal grease is provided between the cooling end of the thermoelectric cooler 39 and the heat-conducting plate 38.

[0023] When the temperature is too high, the semiconductor cooling chip 39 can be activated to electrically cool the coolant, which can further improve the heat dissipation effect and avoid affecting the heat dissipation effect of the stator.

[0024] In this technical solution, corresponding temperature sensors and controllers are installed inside and outside the coolant storage tank 34, respectively. The temperature sensors can sense the temperature, and with the cooperation of the controller, the operation of the cooling fan 37 and the semiconductor cooling chip 39 can be controlled. This is a common technical means used by those skilled in the art and belongs to the prior art.

[0025] A heat-conducting layer 4 is fixedly sleeved on the outer surface of the stator body 1, and an insulating layer 5 is fixedly connected between the heat-conducting layer 4 and the heat dissipation sleeve 31.

[0026] This facilitates heat conduction and insulation of the stator.

[0027] Working principle: When in use, the circulation pump 35 runs to drive the coolant circulation. The spiral heat exchange tube 33 can increase the heat dissipation area of ​​the coolant on the stator, thereby improving the heat dissipation effect.

[0028] The operation of the cooling fan 37 can drive airflow, which, together with the U-shaped heat sink 36, can cool the coolant and prevent it from affecting the heat dissipation effect.

[0029] When the temperature is too high, the semiconductor cooling chip 39 can be activated to electrically cool the coolant, which can further improve the heat dissipation effect and avoid affecting the heat dissipation effect of the stator.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
