具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
如图1至图17所示，本公开实施例的本公开实施例的电机驱动器100包括壳体1、风扇3和散热器组件2。壳体1具有容纳腔以及与容纳腔连通的进风口1011和出风口102。风扇3设于容纳腔内，风扇3具有风扇进口301和风扇出口302，风扇进口301与进风口1011连通。
散热器组件2设于容纳腔内，散热器组件2包括多个第一翅片和多个第二翅片，多个第一翅片限定出多个第一风道，多个第二翅片限定出多个第二风道，第一风道与风扇出口连通，所第二风道与第一风道连通。
本公开实施例的电机驱动器100在工作过程中，风扇3启动，利用风扇3将冷却流体引入容纳腔内，具体地，冷却流体通过与容纳腔连通的进风口1011流入风扇进口301，并通过风扇出口302流入容纳腔内。
在容纳腔内，容纳腔内的元件将热量传递至散热器组件2，利用散热器组件2的第一翅片和第二翅片与冷却流体进行热传导和热对流，从而将容纳腔内元件的热量传递至冷却流体。之后，冷却流体从出风口102流出壳体1外，将容纳腔内元件的热量带出壳体1外，从而实现对容纳腔内的元件的冷却降温。
由于散热器组件2不仅第一翅片，还包括第二翅片，进而使得散热器组件2的整体有效散热面积较大，从而使散热器组件2的散热性能好。使得电机驱动器100的各元件在适宜的温度下工作，有利于延长电机驱动器100的使用寿命，提高电机驱动器100的可靠性。
因此，本公开实施例的电机驱动器100具有使用寿命长和可靠性高等优点。
本公开实施例的电机驱动器100包括两个方面的实施例。
下面参考图1至图8描述本公开第一方面实施例的电机驱动器100。
本公开实施例的电机驱动器100，多个第一翅片22呈辐射状环形分布，第二翅片23设于第一翅片22的外侧。多个第一翅片22限定出多个第一风道225，多个第二翅片23限定出多个第二风道231。
本公开实施例的电机驱动器100在工作过程中，在容纳腔内，容纳腔内的元件将热量传递至散热器组件2，利用散热器组件2的第一翅片22和第二翅片23与冷却流体进行热传导和热对流，从而将容纳腔内元件的热量传递至冷却流体。之后，冷却流体从出风口102流出壳体1外，将容纳腔内元件的热量带出壳体1外，从而实现对容纳腔内的元件的冷却 降温。
由于散热器组件2不仅包括呈辐射状环形分布的第一翅片22，还包括设于第一翅片22的外侧的第二翅片23，进而使得散热器组件2的整体有效散热面积较大，从而使散热器组件2的散热性能好。使得电机驱动器100的各元件在适宜的温度下工作，有利于延长电机驱动器100的使用寿命，提高电机驱动器100的可靠性。
可选地，冷却流体可以为空气。
在一些实施例中，如图6所示，多个第一翅片22形成有凹陷部223，风扇3的至少一部分设于凹陷部223内。
例如，如图6所示，风扇3整体位于凹陷部223内，风扇3的顶端与第二翅片23的上端面平齐。由此，在满足电机驱动器100散热性能的同时，还可以减小电机驱动器100在厚度方向的尺寸，从而使得电机驱动器100结构紧凑，体积较小。
当然，风扇3也可以仅部分位于凹陷部223内，也就是说，风扇3的上端面高于第二翅片23的上端面。
可选地，第一翅片22上设有第一连接柱222，风扇3与第一连接柱222通过第一紧固件224相连。
例如，如图6所示，第一连接柱222竖直设置且设有四个，第一连接柱222呈两排两列布置。每个第一连接柱222上开设有第一螺纹孔，风扇3上开设有与第一螺纹孔一一对应的第一连接孔，第一连接孔为沉孔，第一紧固件224为沉头螺钉，沉头螺钉穿过第一连接孔并与对应的第一螺纹孔螺纹连接，实现风扇3与第一翅片22的连接。
具体进行风扇3的安装时，首先将风扇3放置在第一翅片22上，使风扇3上的四个第一连接孔与四个第一螺纹孔一一对应，然后将沉头螺钉穿过第一连接孔并与第一螺纹连接，从而完成对风扇3的紧固。
在一些实施例中，如图6所示，散热器组件2包括基板21，基板21设于容纳腔内，基板21与壳体1相连，第一翅片22和第二翅片23均设于基板21的上表面。电机驱动器100包括第二电容5，第二电容5设于容纳腔内，基板21具有第一避让口2141，第二电容5的一部分位于第一避让口2141内，第二风道231的出口朝向第二电容5。
一方面，第二电容5的一部分位于第一避让口2141内，使得散热器组件2的结构紧凑，有利于缩小电机驱动器100的整体体积。另一方面，第二风道231的出口朝向第二电容5，从而第二风道231流出的冷却流体可以流经第二电容5，流经第二电容5的了冷却流体与第二电容5进行强制对流，从而利用冷却流体将第二电容5的一部分热量带出壳体1外，实现对第二电容5的冷却降温，有利于进一步提高电机驱动器100的可靠性。
由此，本公开实施例的电机驱动器100在满足电机驱动器100整体结构紧凑的同时，还能进一步提高电机驱动器100的可靠性。
在一些实施例中，如图4和图7所示，电机驱动器100包括第一元件6和第二元件， 第一元件6和第二元件均设于容纳腔内，第一元件6设于基板21的下表面，第二元件设于基板21的下方，且第二电容5位于第二元件的外侧。
由此，本公开实施例的电机驱动器100的第一元件6与基板21可以进行热传导，将第一元件6产生的热量传递至基板21，通过基板21将第一元件6产生的热量传递至第一翅片22和第二翅片23。最终通过流经第一风道221和第二风道231的冷却流体将第一元件6产生的热量带出壳体1外，实现对第一元件6的冷却降温，从而进一步提高电机驱动器100的可靠性。
可选地，第一元件6可以是IPM模块、整流桥或IGBT模块等高功耗芯片，第二元件可以是二极管、电源、电容或电阻等关键器件。

过流孔2151与第一风道225连通，使得从第一风道225的出口流出的一部分冷却流体可以经过流孔2151流出，并直接吹向第二元件，利用第一风道225流出的冷却流体直接与第二元件进行强制对流，并通过吹向第二元件的冷却流体将第二元件的热量带出壳体1外，有利于提高第二元件的散热性能，降低第二元件的温度，有利于进一步提高电机驱动器100的可靠性。
可选地，如图7所示，本公开实施例的电机驱动器100的第一避让口2141设置在第二部分214上，第二元件设于第二部分214的下方，充分利用容纳腔的空间设置元件，以使电机驱动器100的整体布局结构紧凑，进而使电机驱动器100的整体体积较小。从第一风道225的出口流出的一部分冷却流体可以经过流孔2151流出，并直接吹向位于第一避让口2141内的第二电容5，以便冷却流体与第二电容5进行热对流，从而更有效地对第二电容5进行冷却，有利于进一步提高电机驱动器100的可靠性。
可选地，第一翅片22为矩形板，第一翅片22沿环形的中心至外周的方向延伸。
由此，第一翅片22的结构简单，方便设计加工。
可选地，多个第一翅片22沿环形的周向间隔布置，相邻两个第一翅片22之间限定出一个第一风道225。
可选地，第二翅片23为矩形板，第二翅片23沿远离第一翅片22的方向延伸。
由此，第二翅片23的结构简单，方便设计加工。
可选地，多个第二翅片23相互平行且间隔布置，相邻两个第二翅片23之间限定出一个第二风道231。
例如，如图3所示，多个第二风道231相互平行，且均朝向第一出风口1041。
由此，便于流经第二风道231的冷却流体快速流出，有利于进一步提高电机驱动器100的散热效果。
在一些实施例中，壳体1包括第一侧板101和第四侧板104。第一侧板101设于散热器组件2的上方，进风口1011设于第一侧板101，第四侧板104设于散热器组件2的宽度方向的一侧。第二翅片23在散热器组件2的宽度方向上相对第一翅片22更邻近第四侧板104设置。出风口102包括第一出风口1041出风口102，第一出风口1041出风口102设于第四侧板104。第二风道231沿散热器组件2的宽度方向延伸，第二风道231的出口在散热组件2的宽度方向上对应第一出风口1041设置。

第一元件6位于第一翅片22的正下方并安装在基板21的下表面。第四侧板104位于散热器组件2的左侧，第二翅片23位于第一翅片22的左侧，以使第二风道231的出风口102靠近第一出风口1041，从而保证冷却流体在对第二电容5散热效果的同时，便于流经第二电容5的冷却流体快速从第一出风口1041流出，有利于提高对第二电容5的散热效果。
可选地，多个第二翅片23的延伸方向均相同，均沿散热器组件2的宽度方向延伸，以便流经第二电容5的冷却流体快速从第一出风口1041流出，从而进一步提高对第二电容5的散热效果。

例如，如图8所示，第二翅片23设在第一翅片22的左侧，第三翅片24设于第一翅片22的右侧，冷却流体进入容纳腔后，一部分冷却流体经过第一风道225向左流入第二风道231，冷却流体对第二电容5和第二元件进行冷却降温后经第一出风口1041流出壳体1。另一部分冷却流体经过第一风道225向右流入第三风道241，之后经出风口102流出。
本公开实施例的电机驱动器100通过利用第一翅片22、第二翅片23和第三翅片24将热量传导给第一风道225、第二风道231和第三风道241内的冷却流体并经出风口102流 出壳体1来进行散热，使得散热器组件2的散热面积较大，从而进一步提高散热器组件2的散热性，使得电机驱动器100的散热性能较好。
在一些实施例中，如图6图8所示，壳体1包括第一侧板101和第三侧板103。第一侧板101设于散热器组件2的上方，进风口1011设于第一侧板101，第三侧板103设于散热器组件2的宽度方向的一侧。第三翅片24在散热器组件2的宽度方向上相对第一翅片22更邻近第三侧板103设置。出风口102包括第二出风口1031出风口102，第二出风口1031出风口102设于第三侧板103，第三风道241向外延伸至第二出风口1031处。

本公开实施例的电机驱动器100通过利用第三翅片24提高散热面积的同时，还有利于流经第三翅片24的冷却流体快速从第二出风口1031流出，从而提高的散热器组件2的散热效率，进而使电机驱动器100的散热性能较好。
可选地，多个第三风道241的延伸方向均不相同，以便于流入第三风道241内的冷却流体可以快速从第二出风口1031流出壳体1外，从而有利于进一步提高电机驱动器100的散热效率，提高电机驱动器100的可靠性。

另外，第一电容9的一部分位于第二避让口401内，一方面，使得散热器组件2的结构紧凑，有利于缩小电机驱动器100的整体体积。另一方面，第一风道225的出口朝向第一电容9，从而第一风道225流出的冷却流体可以流经第一电容9，流经第一电容9的了冷却流体与第一电容9进行热对流，从而利用冷却流体将第一电容9的一部分热量带出壳体1外，实现对第一电容9的冷却降温，有利于进一步提高电机驱动器100的可靠性。

由此，第一风道2021和第二风道2031互不干涉，有利于减小冷却流体的流动阻力，从而提高电机驱动器100的散热效果。
可选地，第一翅片202、第二翅片203与基板201一体成型。
在一些实施例中，多个第一风道2021沿散热组件2的宽度方向(如图12所示的左右方向)延伸，多个第一翅片202沿散热组件2的长度方向(如图12所示的前后方向)成多排布置，多排第一翅片202沿散热组件2的长度方向(如图12所示的前后方向)间隔布置。由此，有利于进一步提高散热组件2的散热面积，提高电机驱动器100的散热性能。
例如，如图12所示，多个第一翅片202在前后方向间隔布置形成多排第一翅片202，相邻的两排第一翅片202在前后方向上间隔布置。
在一些实施例中，每排第一翅片202包括多个第一翅片202，位于同一排的多个第一翅片202沿散热组件2的宽度方向(如图12所示的左右方向)间隔布置，相邻两排第一翅片202中的任意两个在散热组件2的宽度方向(如图12所示的左右方向)上错开布置。
例如，如图12所示，前后相邻两排第一翅片202中，位于前排的第一翅片202与位于后排的任意一个第一翅片202均在左右方向上错开布置。换言之，多个第一翅片202成多列布置，多列第一翅片202沿第一方向间隔布置，第一方向与散热组件2的长度方向(如图12所示的前后方向)的夹角小于90°。由此，利于从风扇进口进入的冷却流体，进入各个第一风道2021内进行散热，有利于进一步提高电机驱动器100的散热性能。
可选地，第二翅片203为矩形板，第二翅片203中至少一部分沿远离第一翅片202的方向延伸。

例如，如图11和图12所示，第一翅片202和第二翅片203设在基板201的上表面上。
由此，利用流经第一风道2021的冷却流体与第二电容5进行热对流，从而对第二电容5进行冷却降温，有利于进一步提高电机驱动器100的散热性能。此外，第二电容5安装在第一避让口2013内，使得电机驱动器100整体结构紧凑。

例如，如图9和图11所示，第一侧板101设在壳体1的上方，进风口1011设在第一侧板101上，换言之，进风口1011设在壳体1的上方。风扇3位于第一侧板101的下方。风扇进口301和风扇出口302在上下方向上相对设置，风扇出口302位于风扇进口301的下方。风扇进口301位于进风口1011的下方，以便风扇进口301与进风口1011连通。第一翅片202和第二翅片203中的每一者位于风扇出口302的下方，以便第一风道2025和第二风道2031中的每一者与风扇出口302连通。从而利用风扇3使冷却流体经进风口1011、风扇进口301和风扇出口302快速进入第一风道2021和第二风道2031内。
第三侧板103即为壳体1的左侧板，出风口102设在左侧板上。第二电容5与第三侧板103之间的距离小于第一翅片202与第三侧板103之间的距离。
可选地，出风口102设有多个，多个出风口102在左侧板上间隔布置。
由此，在保证流经第一风道2021的冷却流体对第二电容5进行冷却散热的同时，便于流经第二电容5的冷却流体快速从第一出风口1031流出，有利于提高散热效果，从而提高电机驱动器100的可靠性。
在一些实施例中，壳体1包括第四侧板104，在第四侧板104上设有第二出风口1041。第四侧板104即为壳体的右侧板，由此，冷却气流对从靠近壳体1的右侧板设置的电子元件散热后，方便从第二出风口1041流出。

如图11所示，控制板4设在容纳腔的前端，部分第二风道2031的出口朝向控制板4或者所有第二风道2031的出口均朝向控制板4。
由此，从第二风道2031流出的冷却流体可以与控制板4进行对流换热，从而利用流经第二风道2031的冷却流体对控制板4进行冷却，以便控制板4散热，提高控制板4的运行稳定性，进一步提高电机驱动器100的可靠性。
在一些实施例中，如图12所示，电机驱动器100包括第一电容9，第一电容9设于控 制板4的下方，至少一部分第二风道2031的出口朝向第一电容9。

在一些实施例中，散热组件2包括第三翅片2016，第三翅片2016设于第二翅片203的外侧。第三翅片2016和第一翅片202设于第二翅片203的不同侧，多个第三翅片2016之间限定出多个第三风道20161，第三风道20161与第二风道2031连通。
例如，如图12所示，第三翅片2016设在第二翅片203的左侧和右侧，第一翅片202设在第二翅片203的后侧。多个第三翅片2016间隔布置，相邻的两个第三翅片2016限定出第三风道20161，第三风道20161与第二风道2031的出口连通，使得从第二风道2031的出口流出的冷却流体能够进入第三风道20161内。
由此，设置第三翅片2016不仅能增加散热组件2的有效散热面积，而且利用第三翅片2016能够进一步扩散冷却流体，提高散热组件2的散热性能。
可选地，第三翅片2016为矩形板，第三翅片2016沿远离第二翅片203的方向延伸。
由此，第三翅片2016的结构简单，方便设计加工。

例如，如图9和图12所示，多个第三风道20161均沿左右方向延伸，且均朝向第一出风口1031。

中间部分20153上具有与第二风道2031连通的过流孔201531，使得过流孔201531能够连通第二风道2031和第三风道20161，以便于冷却流体从第二风道2031进入第三风道20161内，从而与第二元件7进行强制对流换热，进而降低第二元件7的温度。
在一些实施例中，第二部分20152设有多个，第一部分20151在散热组件2的宽度方向(如图14所示的左右方向)上位于其中两个第二部分20152之间。
例如，如图14所示，第二部分20152设有两个，第一部分20151位于两个第二部分20152之间。
由此，第一分部20151上的第二风道能够与多个第二部分20152上的第三风道连通，从而能够分别通过流经每个第二部分20152的冷却流体，对多个不同的第二元件7分别进行冷却散热能，有利于进一步提高电机驱动器100的可靠性。
