为了更清楚地说明本发明实施例中的技术方案， 下面将对实施例描述中 所需要使用的附图作简单地介绍。

图 6为本发明实施例提供的应用了侧立磁场电机的散热风扇结构示意图。 具体实施方式
下面结合附图对本发明实施例侧立磁场电机进行详细描述。
本发明实施例提供一种侧立磁场电机， 如图 2 所示， 包括定子， 定子包 括本体 21及设在本体 21上的线圈 22 , 侧立磁场电机还包括固定定子的机座 23 ,定子上设有具有传热材质的导热结构；导热结构与机座 23相接触并连接。
本发明实施例提供的侧立磁场电机中， 包括有由本体及设在本体上的线 圈构成的定子， 该定子固定在侧立磁场电机的机座上， 且定子上设有传热材 质制成的导热结构， 该导热结构与机座接触并连接。 由此分析可知， 通过在 本体和 /或线圈上设置由传热材质制成的导热结构， 能够将线圈工作过程中产 生的热量通过线圈自身和 /或本体传递到导热结构中， 再将热量传递到与导热 结构相接触并连接的机座中， 由于导热结构由传热材质制成， 具有良好的导 热性能， 能够保证将线圈产生的热量及时、 有效地通过导热结构传递到机座 中， 从而通过机座及时将热量散发到空气中， 满足了侧立磁场电机的散热需 求， 提高了侧立磁场电机的功率密度， 实用性高。
其中， 导热结构在定子上的设置位置和方式不同， 其所采用的材质、 结 构等也不同， 但需要保证导热结构为传热性能良好的材质。
此外， 侧立磁场电机通常用于散热风扇 （侧立式磁场电机） 中， 因此， 为了便于说明本实施中侧立磁场电机的散热过程及其应用场景， 以侧立磁场 电机及应用其的散热风扇为例。 如图 2 所示， 其中， 散热风扇包括风扇框体 24, 通过支撑架 25与风扇框体 24固定连接的风扇底座 26, 风扇底座 26与机 座 23固定连接， 侧立磁场电机用于连接风扇叶片 （图 2中未示出 ) , 从而能 够驱动风扇叶片转动。 在实际应用时， 定子本体 21可以为电磁性能良好的矽 钢片， 且本体 21通常为筒状结构， 可以为圓筒状结构， 便于本体 21上的线 圈 22驱动风扇叶片转动。
具体地， 如图 2所示， 导热结构包括穿设在圓筒状定子本体 21中的圓柱 状导热柱 27, 相应的本体 21上需要设置容纳该导热柱 27的通孔， 且导热柱 27也可以为长方体、 锥形体等结构。 图 2中， 为了保证定子结构的整体性， 导热柱 27的第一端位于本体 21内部， 可以与本体 21上端面共面设置， 导热 柱 27的第二端凸出于本体 21夕卜， 从而该端能够插入并固定在机座 23中。 由 此可知， 线圈 22工作过程中产生的热量首先传递给本体 21 , 再通过本体 21 传递给传热材质的导热柱 27, 进而通过导热柱 27传递给机座 23 , 最后通过 机座 23能够传递给与之固定连接的风扇底座 26。 图 2中， 风扇底座 26中的 热量还能够通过支撑架 25进行散发， 且在图 2中， 箭头方向为散热风扇工作 时产生的气流流动方向， 由此可知， 该气流能够将支撑架 25 和风扇底座 26 中的热量带走， 达到快速散热的目的。
其中， 机座 23、 风扇底座 26及支撑架 25均可以选用导热性能良好的材 质， 例如金属、 陶瓷等。 且支撑架 25上可以根据结构要求增设散热齿， 从而 提高支撑架 25的散热能力。 其中， 机座 23与风扇底座 26可以为两个部件， 并通过焊接、 过盈配合等方式固定连接； 也可以为了缩短热传递路径， 将机 座 23与风扇底座 26—体成型设置。
在实际应用时， 为了提高导热柱 27对热量的传递作用， 可以设置多个导 热柱 27, 从而多个导热柱 27沿一个本体 21的周向方向等距、 均勾排布。 其 中， 线圈 22在本体 21上的布置方式通常为等距、 均勾排布， 因此可以将导 热柱 27设在相连线圈组之间， 保证整体布置合理性， 且导热柱 27均勾传递 线圈 22的热量， 避免局部过热的现象。
进一步地， 为了提高本体 21与导热柱 27之间的热交换， 通常可以增大 两者之间的接触面积， 同时保证两者之间为无缝隙接触。 具体地， 根据本体 21的侧壁厚度， 可以将导热柱 27的直径设为与侧壁厚度相符的数值（直径小 于侧壁厚度） ， 同时两者之间通过过盈配合减小缝隙， 保证充分接触。 其中， 导热柱 27与本体 21之间也可以为焊接方式固定， 从而保证两者之间无缝隙 , 且金属降低了散热的热阻， 提高传热能力， 进而提高散热能力。
另外， 也可以在导热柱 27穿设入本体 21中之后， 通过在导热柱 27与本 体 21通孔内壁之间填充导热材料， 从而在完成导热柱 27的固定的同时， 提 高导热柱 27与本体 21之间的热传递效率。
导热柱 27可以通过焊接的方式固定在机座 23上， 焊接能够减小散热的 热阻， 加速散热。 当然， 导热柱 27也可以采用胶粘、 过盈配合连接等固定连 接。
此处需要说明的是， 图 2中， 导热柱 27还需要穿设过本体 21上下端面 与线圈 22之间的绝缘片。 图 2中的散热途径主要通过多个导热柱 27及时将热量传递到机座 23 ,进 而传递到风扇底座 26、 支撑架 25上等， 其散热效率取决于导热柱 27的传热 效率， 因此， 此时机座 23与风扇底座 26可以采用固定连接的方式。 当然， 也可以通过图 3所示的导热结构， 具体如下。
图 3中， 导热结构包括两个环状第一导热架 31 , 两个第一导热架 31分别 位于定子本体 21 的上、 下端面， 且线圈 22按现有技术中的方式缠绕在上下 第一导热架 31与本体 21上， 如图 3所示。 由此可知， 线圈 22工作过程中产 生的热量主要通过线圈 22传递给本体 21 , 再通过本体 21传递给位于本体 21 下端的第一导热架 31 , 进而传递给与该端第一导热架 31固定连接的机座 23 ; 还有一部分热量通过线圈 22直接传递给第一导热架 31 , 在通过位于本体 31 下端的第一导热架 31传递给机座 23。 图 3中， 本体 21可以为圓筒状结构， 则第一导热架 31可以设置为与本体 21形状相匹配的圓环状。
最后通过机座 23能够传递给与之固定连接的风扇底座 26。 图 3中， 风扇 底座 26中的热量还能够通过支撑架 25进行散发， 且在图 3中， 箭头方向为 散热风扇工作时产生的气流流动方向， 由此可知， 该气流能够将支撑架 25和 风扇底座 26中的热量带走， 达到快速散热的目的。
其中， 机座 23、 风扇底座 26及支撑架 25均可以选用导热性能良好的材 质， 例如金属、 陶瓷等。 且支撑架 25上可以增设散热齿， 从而提高支撑架 25 的散热能力。 其中， 机座 23与风扇底座 26可以为两个部件， 并通过焊接、 过盈配合等方式固定连接； 也可以为了缩短热传递路径， 将机座 23与风扇底 座 26 —体成型设置； 本实施例中由于主要通过位于本体 21下端的第一导热 架 31传递热量， 从而为了有效缩短热传递路径， 将机座 23与风扇底座 26— 体成型设置， 以加快热量的散发。
当通过螺钉连接或粘接配合的方式将位于本体 21 下端的第一导热架 31 固定在机座 23上时， 由于线圈 22同时缠绕在第一导热架 31上， 因此下端区 域的线圈 22会与机座 23相接触， 从而线圈 22产生的热量还有一部分能够直 接传递给机座 23 , 从而通过多方位的散热途径， 提高线圈 22的散热效率。 为了进一步提高位于本体 21下端的第一导热架 31 的传热效率， 可以在 不妨碍该端第一导热架 31 的与机座 23 固定的同时， 在两者之间填充导热材 料。 同时， 还可以在线圈 22与机座 23之间填充导热材料， 便于热量快速的 传递。 其中， 第一导热架 31可以采用导热性能很强的 A1N陶瓷材料。
为了进一步保证第一导热架 31与机座 23的连接稳定性， 如图 4所示， 可以在本体 31下端面的第一导热架 31上， 沿平行于本体 31中心线方向设置 多个均匀、 等距排布的柱状体 41 , 该柱状体 41与穿设在机座 23中并与机座 23固定连接。 同时， 该些柱状体 41还能够起到传热的作用。
此处需要说明的是， 图 3中， 位于本体 21上下端面的第一导热架 31也 可以直接作为绝缘片使用， 此时位于本体 21上端的第一导热架 31也能够传 热， 该部分热量能够通过定子与转子之间的间隙散发。 当然， 可以在本体 21 下端设置第一导热架 31 , 上端仍然采用绝缘片结构。
其中， 图 3中采用缩短热传递路径的方式， 即机座 23与风扇底座 26— 体成型设置， 可以减小整体厚度， 便于热量快速传递到支撑架上等， 该种方 式实施简单， 有效。 此时， 机座 23也可以称为风扇底座 26, 或底座。
在应用磁场电机时， 由于主要的发热源为线圈 22, 则可以通过直接改变 线圈 22的结构来提高其散热效率， 具体如图 5所示。
图 5中， 线圈 22包括多个间隔设置的条状结构的金属条， 导热结构则为 设于定子与机座 23之间的互连板 51 ,该互连板 51与机座 23固定连接。其中， 由金属条构成的线圈 22相比传统绕制线圈 22, 在相同周向长度下，金属条的 截面面积大， 电阻小， 从而其向下导热能力强， 自身发热也小。 其中， 每个 金属条包括两个相互平行的片状体， 两个片状体分别贴附在本体 21的内、 外 侧壁上， 且两个片状体第一端相连接， 第二端通过与互连板 51内部的电路实 现电连接， 从而使金属条和互连板 51 内部的电路共同形成线圈 22的导电通 路。 具体地， 互连板 51上表面可以设有焊盘， 而两个片状体的第二端设有与 焊盘固定连接的延伸端。 其中焊盘与延伸端一一对应设置， 即每个金属条包 括有两个延伸端， 两个延伸端则分别对应有一个焊盘， 且两个延伸端之间不 直接相连。 这其中， 每个金属条的两个延伸端间隔、 相背设置， 从而使每个 金属条构成类似 "几" 型结构， 片状体可以竖直设置、 延伸端则垂直于片状 体水平设置。 图 5中， 焊盘可以通过电镀或热压的方式固定在互连板 51上， 且互连板内部还设有与焊盘相连通的电路， 该电路可以通过电镀或热压的方 式设在互连板 51内部， 同时通过焊接的方式与焊盘相连， 以便后需要与金属 条的连接。
将两个片状体分别贴附在本体 21的内、 外侧壁时， 两个片状体相连接的 端部与本体 21的顶端面相贴合， 此时要求该端部的长度 (两个片状体之间的 距离） 与本体 12的厚度相一致。 图 5中， 本体 21可以为圓筒状结构， 则互 连板 51可以为中空圓盘状结构， 且互连板 51的外直径大于本体 21直径， 从 而互连板 51便于承载本体 21、 便于与延伸端固定连接。 图 5中， 每个金属条 按上述方式固定在本体 21上， 同时， 多个金属条沿本体 21周向方向等距、 均匀排布。 当然， 多个金属条在本体 21上的排列方式有多种， 图 5中的方式 为较合理、 外观性较整齐的一种布置方式。
在金属条贴附完成之后， 每个金属条均通过各自的焊盘与电路相连通， 从而所有的金属条与电路能够共同构成线圈的导电通路， 以便于连接外接电 源。 其中， 互连板 51内的电路需按照线圈导电通路的连线要求布置。 互连板 51可以通过胶粘的方式固定在机座 23上， 且互连板 51的材质可以为 A1N陶 瓷材料。
两个片状体分别贴附在本体 21侧壁的内、 外侧面上， 再将延伸端通过焊 接的方式固定在焊盘上， 从而完成线圈 22的固定。 由此可知， 线圈 22产生 的热量主要通过线圈 22直接传递给焊盘， 再通过焊盘传递到互连板 51 , 再通 过互连板 51传递给机座 23。 其中， 金属条的延伸端与焊盘焊接时， 由于焊料 的存在， 金属条也可以通过焊料与互连板之间传递热量， 从而加快线圈 22热 量的散发。
最后通过机座 23能够传递给与之固定连接的风扇底座 26。 图 5中， 风扇 底座 26中的热量还能够通过支撑架 25进行散发， 且在图 5中， 箭头方向为 散热风扇工作时产生的气流流动方向， 由此可知， 该气流能够将支撑架 25和 风扇底座 26中的热量带走， 达到快速散热的目的。
其中， 机座 23、 风扇底座 26及支撑架 25均可以选用导热性能良好的材 质， 例如金属、 陶瓷等。 且支撑架 25上可以增设散热齿， 从而提高支撑架 25 的散热能力。 其中， 机座 23与风扇底座 26可以为两个部件， 并通过焊接、 过盈配合等方式固定连接； 也可以为了缩短热传递路径， 将机座 23与风扇底 座 26 —体成型设置； 本实施例中由于主要通过互连板 51传递热量， 为了有 效缩短热传递路径， 将机座 23与风扇底座 26 —体成型设置， 以加快热量的 散发。
图 5中， 为了拓展线圈 22的散热途径， 即通过本体 21进行部分热量的 散发， 也可以在本体 21的上下端面设置第二导热架 52 , 该第二导热架 52可 以为与本体 21相匹配的圓环状结构。 其中位于本体 21下端的第二导热架 52 的上端面与本体 21底断面固定连接、下端面则与互连板 51相接触和 /或连接， 从而线圈 22的部分热量能够通过本体 21传递到位于本体 21下端的第二导热 架 52 , 再通过该端第二导热架 52传递给互连板 51 , 进而传递给机座 23等进 行快速的热量散发。 另外， 由于金属条采用贴附方式， 因此金属条的底端部 分（片状体的第二端）还会与位于本体 21底端的第二导热架 52的侧表面相 接触， 增加了传热路径。
此处需要说明的是， 第二导热架 52可以代替本体 21 上下端面绝缘片。 其中， 图 5中采用缩短热传递路径的方式， 即机座 23与风扇底座 26—体成 型设置， 可以减小整体厚度， 便于热量快速传递到支撑架上等， 该种方式实 施简单， 有效。 此时， 机座 23也可以称为风扇底座 26, 或底座。 通常， 相比现有技术中的侧立磁场电机， 采用如图 2至图 5所示的导热 结构， 能够有效提高侧立磁场电机的散热效率， 同时采用如图 2 所示的导热 结构， 能够提高 60%的电机功率密度， 在采用图 3和图 5所示的导热结构时， 能够提高 100%的电机功率密度， 实用性高。
本发明实施例还提供一种散热风扇， 包括风扇框体、 通过支撑架与风扇 框体固定连接的风扇底座， 及风扇叶片， 还包括用于驱动风扇叶片转动的上 述实施例描述的侧立磁场电机； 侧立磁场电机的机座与风扇底座固定连接。
本发明实施例还提供的散热风扇中， 由于使用了上述实施例描述的侧立 磁场电机， 该侧立磁场电机包括有由筒状本体及设在本体上的线圈构成的定 子， 该定子固定在侧立磁场电机的机座上， 且定子上设有导热材质制成的导 热结构， 该导热结构与机座接触并连接。 由此分析可知， 通过在本体和 /或线 圈上设置由传热材质制成的导热结构， 能够将线圈工作过程中产生的热量通 过线圈自身和 /或本体传递到导热结构中， 再将热量传递到与导热结构相接触 并连接的机座中， 由于导热结构由传热材质制成， 具有良好的导热性能， 能 够保证将线圈产生的热量及时、 有效地通过导热结构传递到机座中， 从而通 过机座及时将热量散发到空气中， 满足了侧立磁场电机的散热需求， 提高了 侧立磁场电机的功率密度， 实用性高。
其中， 机座与风扇底座之间可以通过焊接或过盈配合固定连接； 或， 机 座与风扇底座为一体成型结构， 如果选择为后者， 能够缩短传热路径。 根据 侧立磁场电机不同的导热结构， 可以选择机座与风扇底座不同的连接结构， 应用广泛， 且该种选择方式在上述实施例中已进行描述， 再次不在赘述。
进一步地， 支撑架上可以设有散热齿结构， 从而加快热量在支撑架位置 处的散发， 从而提高整体散热效率。 散热齿结构可以根据需要而设定。
其中， 图 6为应用了侧立磁场电机 62的散热风扇 61。
