Description

一种基于I型均热板的散热结构及平板直线电机A heat dissipation structure based on I-type heat spreader and a flat linear motor 技术领域Technical Field
本发明涉及平板直线电机技术领域，具体涉及一种基于I型均热板的散热结构及平板直线电机。The present invention relates to the technical field of flat linear motors, and in particular to a heat dissipation structure based on an I-type heat spreader and a flat linear motor.
背景技术Background technique
随着电机向高功率密度等方向发展，随之带来了发热量急剧增大的问题。因此，散热是制约电机发展的重要因素，能否有效解决电机发热问题已成为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。As motors develop towards high power density and other directions, the problem of rapidly increasing heat generation has arisen. Therefore, heat dissipation is an important factor restricting the development of motors. Whether the problem of motor heating can be effectively solved has become the key to whether the motor can increase its limit power and achieve lightweight. Natural air cooling and liquid cooling are the mainstream linear motor heat dissipation technologies. The principle is that the motor copper wire winding transfers heat to the outer casing through the insulation layer and iron core, and then the heat is dissipated by air or liquid working fluid.
远离冷却模块靠近磁钢的绕组的热量的传热路径有两条：①发热绕组的热量横向传递给铁芯，热量在铁芯内纵向传递至冷却模块。②热量通过绕组内部纵向向上传递至铁芯与冷却模块。但是，因为铁芯本身热导率不高，且绕组上绝缘漆和气隙对热量的传递影响，导致热阻极大，无法实现直线电机内部绕组的有效散热。该部分铜线温度已成为衡量直线电机是否达到保护温度的重要指标。There are two heat transfer paths for the heat of the windings far away from the cooling module and close to the magnetic steel: ① The heat of the heating winding is transferred horizontally to the iron core, and the heat is transferred longitudinally inside the iron core to the cooling module. ② The heat is transferred vertically upward to the iron core and the cooling module through the inside of the winding. However, because the thermal conductivity of the iron core itself is not high, and the insulating paint and air gap on the winding affect the heat transfer, the thermal resistance is extremely large, and effective heat dissipation of the winding inside the linear motor cannot be achieved. The temperature of this part of the copper wire has become an important indicator to measure whether the linear motor has reached the protection temperature.
因此，提高铁芯的热传递效率对于降低内部绕组温度对实现直线电机高效散热与功率提升具有重要意义。Therefore, improving the heat transfer efficiency of the core is of great significance for reducing the internal winding temperature and achieving efficient heat dissipation and power improvement of the linear motor.
发明内容Summary of the invention

The heat dissipation structure improves the longitudinal heat transfer efficiency of the rotor core while reducing the thermal resistance between the windings and between the windings and the rotor core, thereby significantly improving the heat dissipation efficiency of the internal windings and increasing the motor's power.

如图6所示，本实施例的平板直线电机与实施例3的区别在于，冷却模块3中对应于均热板2同样设置有插槽13，均热板2的上端插入冷却模块3的插槽13中，进一步地增大均热板2与冷却模块3的接触面积，显著提升均热板2的传热效率，提升热量沿绕组支撑柱纵向12传递的热导率。As shown in Figure 6, the difference between the flat linear motor of this embodiment and embodiment 3 is that a slot 13 is also provided in the cooling module 3 corresponding to the heat spreader 2, and the upper end of the heat spreader 2 is inserted into the slot 13 of the cooling module 3, thereby further increasing the contact area between the heat spreader 2 and the cooling module 3, significantly improving the heat transfer efficiency of the heat spreader 2, and improving the thermal conductivity of heat transferred along the longitudinal direction 12 of the winding support column.
