具体实施方式
于以下说明中，如有指出请参阅特定附图或是如特定附图所示，其仅是用以强调于后续说明中，所述及的相关内容大部分出现于该特定附图中，但不限制该后续说明中仅可参考所述特定附图。
请一并参阅图1至图4，图1及图2显示为本发明的马达的不同视角的立体示意图，图3及图4显示为本发明的马达的不同视角的分解示意图。本发明的马达100包含一马达壳体组件1及一马达电机2。马达壳体组件1包含：一中空外壳11、一中空内壳12及两个端盖13。
中空外壳11的一内侧面111向外延伸形成有一第一螺纹结构112，中空外壳11的两端具有一流入口113及一流出口114。中空内壳12的一外侧面121向外延伸形成有一第二螺纹结构122，中空外壳11的第一螺纹结构112与中空内壳12的第二螺纹结构122相互锁合。
马达电机2设置于中空内壳12中，马达电机2包含一定子组件21、一转子组件22及一转动轴23，定子组件21固定于中空内壳12的一内侧面111，转子组件22与转动轴23相互固定。当马达电机2通电时，转子组件22及转动轴23能相对定子组件21旋转。关于定子组件21固定于中空内壳12中的方式可以是依据定子组件21的形式而决定，例如可以是用焊接、紧配合压入等方式。其中，所述定子组件21例如可以是包含有多个硅钢片所构成的一结构体，以及缠绕于所述结构体的线圈，所述转子组件22例如可以是包含有一本体及设置于所述本体内的多个永久磁铁。
两个端盖13固定于中空外壳11及中空内壳12的两端，其中一个端盖13具有一轴孔 131，且转动轴23的一端穿出于所述轴孔131。在具体实施中，各个端盖13可以是通过焊接等方式，与中空外壳11及中空内壳12相互固定，但不以此为限。另外，在特殊的应用中，马达100也可以是不包含两个端盖13。
请一并参阅图5至图7，图5为本发明的马达的局部剖面示意图，图6为图5的侧面示意图，图7为本发明的马达的剖面示意图。中空外壳11及中空内壳12通过第一螺纹结构112及第二螺纹结构122相互锁合后，中空外壳11的内侧面111、第一螺纹结构112、中空内壳12的外侧面121及第二螺纹结构122共同形成一螺旋流道S，螺旋流道S、流入口113及流出口114相互连通，而流入口113用以提供一冷却液体进入螺旋流道S，流出口114则用以提供位于螺旋流道S内的冷却液体流出。
值得一提的是，为利使提供冷却液体的相关设备及回收冷却液体的相关设备，可以分别更好地与流入口113及流出口114相连接，马达壳体组件1还可以是包含有两个管路接头3，两个管路接头3固定(例如是通过焊接等方式)于中空外壳11，且其中一个管路接头3与流入口113相连通，另一个管路接头3则是与流出口114相连通。
在实际应用中，只要冷却液体能通过流入口113进入螺旋流道S中，且冷却液体能通过流出口114向外流出，流入口113及流出口114的设置位置可以是依据需求变化，图中所示仅为其中一示范方式。在特殊的应用中，中空外壳11也可以是包含有多个流入口113及多个流出口114，而中空外壳11不以单一个流入口113及单一个流出口114为限。
关于螺旋流道S的宽度W1及深度H2，皆可依据实际需求(例如马达100的尺寸、转速等)决定，于此不加以限制。较佳地，在螺旋流道S的高度大于3毫米，且螺旋流道S的宽度大于5毫米的实施例中，进入螺旋流道S中的冷却液体，将可以有效地带走马达100运作时所产生的热能，而可大幅地降低马达100的运转时的温度。
在较佳地的应用中，第一螺纹结构112相对于中空外壳11的外侧面的高度可以是介于3毫米至20毫米，第一螺纹结构112的宽度W2可以是介于2毫米至10毫米，且第一螺纹结构112的螺距可以是介于5毫米至100毫米；第二螺纹结构122相对于中空外壳11的外侧面的高度可以是介于3毫米至20毫米，第二螺纹结构122的宽度可以是介于2毫米至10毫米，且第二螺纹结构122的螺距可以是介于5毫米至100毫米。
依上所述，通过第一螺纹结构112及第二螺纹结构122的设计，相关组装人员在组装本发明的马达100时，可以简单地使中空外壳11与中空内壳12相对旋转，即可于中空外壳11与中空内壳12之间形成螺旋流道S。当然，为了提升螺旋流道S的密封性，可以是 通过焊接等方式，将相互锁合的中空外壳11及中空内壳12之间存在的接缝焊死；另外，也可以是通过于中空外壳11与中空内壳12之间设置弹性垫圈(例如俗称的O-ring)，来提升螺旋流道S的密封性。
请一并参阅图3、图4、图6及图7，图7为本发明的马达的沿通过转动轴的中心的截面剖开的剖面示意图。需补充说明的是，中空外壳11具有一中空通道11A，且中空外壳11的其中一端可以是向中空通道11A的方向延伸形成有一环状端壁115，环状端壁115用以限制中空内壳12通过第二螺纹结构122及第一螺纹结构112而相对于中空外壳11的活动范围。通过环状端壁115的设计，相关人员或是机械设备在组装中空外壳11及中空内壳12的过程中，可以通过感受中空内壳12是否已经抵顶于环状端壁115，或是，通过判断中空内壳12与中空外壳11是否已经无法相对旋转时，来判断中空外壳11与中空内壳12是否已经完成锁合。其中，在中空外壳11具有环状端壁115的实施例中。
值得一提的是，在中空外壳11具有环状端壁115的实施例中，其中一个端盖13则可以是固定于环状端壁115的一侧；另外，如图7所示，在于马达100的一截面中，环状端壁115的宽度H1是大于螺旋流道S的深度H2，而中空外壳11及中空内壳12相互锁合时，环状端壁115将是形成螺旋流道S的一部分。
另外，为了使转动轴23可以稳定地转动，在实际应用中，马达100还可以是包含有两个轴承组件4，且各个端盖13可以是具有一容槽132，而各个轴承组件4则是对应固定于容槽132中。转动轴23的两端则是对应固定于两个轴承组件4。所述轴承组件4例如是滚珠轴承，但不以此为限。
综上所述，本发明的马达及马达壳体组件，通过中空外壳的第一螺纹结构及中空内壳的第二螺纹结构等设计，相关人员可以轻易地于马达电机外形成用以提供冷却液体流动的螺旋流道，如此，将可大幅提升马达的组装效率。
以上所述仅为本发明的较佳可行实施例，非因此局限本发明的专利范围，故凡运用本发明说明书及附图内容所做的等效技术变化，均包含于本发明的保护范围内。
