Description

一种复合式相变热控器件及基于其的磁轴直线电机A composite phase change thermal control device and a magnetic axis linear motor based thereon 技术领域Technical Field
本发明涉及电机散热技术领域，具体涉及一种复合式相变热控器件及基于其的磁轴直线电机。The present invention relates to the technical field of motor heat dissipation, and in particular to a composite phase-change thermal control device and a magnetic axis linear motor based thereon.
背景技术Background technique
直线电机相对于传统方式优点显著，可以实现非常高的速度和非常低的速度，具备高加速度、低维护成本、高精度、无空回、无行程限制等特点。与滚珠丝杠传动相比，其速度提高30倍，加速度提高10倍，最大达10g，刚度提高7倍，最高响应频率达100Hz。其缺点也很明确，控制难度较大，对周边产生磁场干扰；并且还有发热量大等问题。Compared with traditional methods, linear motors have significant advantages. They can achieve very high speeds and very low speeds, and have the characteristics of high acceleration, low maintenance cost, high precision, no backlash, and no travel limit. Compared with ball screw transmission, its speed is increased by 30 times, its acceleration is increased by 10 times, up to 10g, its stiffness is increased by 7 times, and its maximum response frequency is 100Hz. Its disadvantages are also very clear. It is difficult to control and generates magnetic field interference to the surrounding area. It also has problems such as high heat generation.
可知，散热是制约直线电机发展的重要因素，能否有效解决直线电机发热问题成为直线电机能否提升极限功率，实现轻量化的关键。自然风冷和液冷是主流的直线电机散热技术，其原理是电机铜线绕组通过绝缘层和铁芯等将热量传至外壳，再由空气或液态工质将热量耗散。It can be seen that heat dissipation is an important factor restricting the development of linear motors. Whether the heating problem of linear motors can be effectively solved is the key to whether linear motors can increase their maximum power and achieve lightweight. Natural air cooling and liquid cooling are the mainstream heat dissipation technologies for linear motors. The principle is that the motor copper wire winding transfers heat to the outer shell through the insulation layer and iron core, and then the heat is dissipated by air or liquid working fluid.
然而，对于磁轴式直线电机，无论是采用液冷散热还是风冷散热，受进出水口和风向的影响，电机内部绕组存在沿轴向温度分布不均匀的问题。且磁轴式直线电机内部绕组环绕磁轴分布，径向和轴向热导率极低，易出现局部高温从而导致电机烧毁。However, for magnetic axis linear motors, whether liquid cooling or air cooling is used, the internal windings of the motors have uneven temperature distribution along the axial direction due to the influence of the water inlet and outlet and the wind direction. In addition, the internal windings of magnetic axis linear motors are distributed around the magnetic axis, and the radial and axial thermal conductivity are extremely low, which is prone to local high temperature and thus causes the motor to burn out.
因此，提升内部绕组沿轴向均温性对实现磁轴式直线电机高效散热与功率提升具有重要意义。Therefore, improving the axial temperature uniformity of the internal winding is of great significance to achieving efficient heat dissipation and power improvement of the magnetic axis linear motor.
发明内容Summary of the invention

本发明中，热管以及超薄均热板的长、宽、厚度及布置数量等参数可以针对不同尺寸、不同工况的直线电机进行定制化设计与制造。In the present invention, parameters such as the length, width, thickness and arrangement quantity of the heat pipe and the ultra-thin heat spreader can be customized for linear motors of different sizes and working conditions.
为了避免热管与超薄均热板之间出现点接触或线接触等接触不充分而导致热阻增大的问题，在接触的位置灌注导热胶，填补其间气隙，减小热阻。所述导热胶可替换为其他导热界面材料，例如导热泥、导热硅脂等。In order to avoid the problem of insufficient contact such as point contact or line contact between the heat pipe and the ultra-thin heat spreader, which leads to increased thermal resistance, thermal conductive glue is poured at the contact position to fill the air gap between them and reduce thermal resistance. The thermal conductive glue can be replaced by other thermal conductive interface materials, such as thermal conductive mud, thermal conductive silicone grease, etc.

The heat of the winding 8 is transferred to the ultra-thin heat spreader 2 through the iron core 5 and quickly transferred to the motor housing 3, thereby solving the problem of uneven temperature distribution along the axial direction of the winding inside the motor and improving the heat dissipation efficiency of the winding.
同样地，本发明中，为了避免热管1、超薄均热板2、绕组8、铁芯5和电机外壳3之间出现点接触或线接触等接触不充分而导致热阻增大的问题，灌注一定量导热胶，填补其间气隙，减小热阻。Similarly, in the present invention, in order to avoid the problem of increased thermal resistance due to insufficient contact such as point contact or line contact between the heat pipe 1, ultra-thin heat spreader 2, winding 8, iron core 5 and motor housing 3, a certain amount of thermal conductive glue is poured to fill the air gap therebetween and reduce the thermal resistance.
本实施例中，热管1、超薄均热板2组成的复合式相变热控器件贯穿电机动子绕组首尾，利用其高热导率特性，建立多条高效率、多层次的散热路径，显著降低磁轴式直线电机动子绕组沿轴向和径向的热阻。In this embodiment, the composite phase change thermal control device composed of the heat pipe 1 and the ultra-thin heat spreader 2 runs through the beginning and end of the motor rotor winding, and uses its high thermal conductivity characteristics to establish multiple high-efficiency, multi-level heat dissipation paths, thereby significantly reducing the axial and radial thermal resistance of the rotor winding of the magnetic axis linear motor.
实施例3Example 3
本实施例与实施例2的不同之处在于，磁轴直线电机中插设的超薄均热板没有热管固定，超薄均热板上不设置通孔，对应地，电机外壳的壳壁上也不设有通孔和热管。具体如图6所示。The difference between this embodiment and embodiment 2 is that the ultra-thin heat spreader inserted in the magnetic axis linear motor is not fixed with a heat pipe, and no through hole is provided on the ultra-thin heat spreader. Correspondingly, no through hole and heat pipe are provided on the shell wall of the motor housing.
以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
