Description

电控盒、控制组件及空调室外机
本申请要求在2021年11月23日提交中国专利局、申请号为202111396445.2的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及空调技术领域，尤其涉及一种电控盒、控制组件及空调室外机。
背景技术
空调室外机是空调运行的重要组成部分，其通常包括压缩机、风机及电控盒等，其中，电控盒内设置有控制压缩机等运行的控制主板及各种电器件，且电控盒能为控制主板提供防水防尘的环境。
由于电控盒内电器件密度通常较高，在控制主板工作时，其上的功率器件和电感类器件会产生大量的热量，容易导致电控盒内温度超标，影响电器件的使用寿命，甚至造成安全隐患。相关技术中，通常在电器盒外部设置散热器进行散热，且在电控盒的盒体上开设通风口，使风机转动产生的气流能够通过散热器及通风口对电控盒内的电器件进行散热。
相关技术提供的电控盒，要么是电器盒内部通过电控盒的盒体侧壁与外部分隔，电控盒内的气流无法直接流向散热器，导致电控盒内部和外部散热性能均不佳，且难以有效发挥散热器的散热作用；要么是电控盒内部通过通风口与外部连通，由于通风口处缺乏挡水防尘结构的设置，由此导致在外部环境的灰尘或水汽容易被气流携带至电控盒内部，降低电控盒的防水性能，或是因挡水防尘结构在通风口处的设置不合理，使得能够满足防水防尘的挡水防尘结构又难以保证良好的散热性能。即，电控盒，难以保证电控盒防水和散热性能的同时满足。
发明内容
本申请的一个目的在于提供一种电控盒，以在保证电控盒的防尘防水性能的同时，提高散热通风性能。
为实现上述目的，本申请采用下述技术方案：
一种电控盒，所述电控盒的一迎风侧壁上设置有通风格栅结构，所述通风格栅结构包括沿所述迎风侧壁的壁厚方向间隔设置的若干层格栅层结构，每个所述格栅层结构均间隔设置有若干个通风口，相邻两层所述格栅层结构的所述 通风口在所述迎风侧壁外壁面的投影错位设置，最外层的所述格栅层结构的所述通风口连通所述电控盒的外部空间，最内层的所述格栅层结构的所述通风口连通所述电控盒的容纳腔。
本申请的有益效果在于：
本申请提供的电控盒，通过沿迎风侧壁壁厚方向间隔设置的若干个格栅层结构，且相邻格栅层结构的通风口错位设置，使得每个通风口均通过相邻两层格栅层结构之间的间隙与另一层的通风口连通，从而使得每层格栅层结构的通风口以及相邻两层格栅层结构之间的间隙共同形成连通电控盒外部空间和内部腔体的通风通道，从而可以使得气流经过容纳腔内对控制器件散热，实现通风格栅结构的通风性；同时，由于相邻格栅层结构的通风口错位设置，当气流由外层格栅层结构的通风口吹向相邻内层格栅层结构时，大部分的气流首先与相邻内层格栅层结构中的隔档结构接触，从而使得气流中携带的部分灰尘和水汽会附着在内层格栅层结构的隔档结构上，从而减小气流将灰尘和水分携带入容纳腔的概率，在保证电控盒的通风散热性能的同时，保证电控盒的防水防尘性能，从而提高电控盒的使用安全性能。
本申请的另一个目的在于提供一种控制组件，以在保证控制组件的散热通风性能的同时，提高控制组件的防尘防水性能，提高控制组件的运行安全性和可靠性。
为实现上述目的，本申请采用下述技术方案：
一种控制组件，包括如上的电控盒，还包括控制板和电性设置在所述控制板上的若干电器件，所述控制板安装于所述电控盒内，且部分所述电器件伸入所述电控盒的容纳腔内。
本申请的有益效果在于：
本申请提供的控制组件，通过采用上述的电控盒，能够在保证电控盒的防水防尘性能的基础上，提高电控盒的散热性能，从而保证控制组件的使用安全性和可靠性。
本申请的又一个目的在于提供一种空调室外机，以提高空调室外机的使用安全性和可靠性。
为实现上述目的，本申请采用下述技术方案：
一种空调室外机，包括机壳和设置在所述机壳内的风机，还包括如上所述的控制组件，所述控制组件设置在所述机壳内，所述迎风侧壁朝向所述风机。
本申请的有益效果在于：
本申请提供的空调室外机，通过采用上述的控制组件，能够在保证对控制组件的防尘防水的保护的基础上，提高控制组件的散热性能，避免控制器件工作在较高温度的环境中，从而提高控制组件的使用安全性和可靠性，进而提高空调室外机的使用安全性和可靠性。

实施例一
如图1和图2所示，本实施例提供了一种空调室外机，其包括机壳20和设置在机壳20内部的压缩机、冷凝器50、风机组件及控制组件10等。机壳20内 部形成有由隔板60分隔的风机腔和压缩机腔，风机组件设置于风机腔中，压缩机设置于压缩机腔中，控制组件10安装于隔板60顶端，冷凝器50设置于风机30的背侧。
风机组件包括风机30、电机及导流罩40，电机安装于机壳20上且输出轴与风机30连接，导流罩40围设于风机30的外侧，以进行气流流向引导和控制。控制组件10包括电控盒1、安装于电控盒1内的控制器件以及安装于电控盒1外侧的散热器4，散热器4位于电控盒1朝向风机30的一侧，电控盒1朝向散热器4的一侧设置有连通电控盒1内外空间的通风通道。风机30的高速旋转带动空气进行流动，被风机30吹动的气流经过散热器4，对散热器4进行散热，降低散热器4温度，同时，经过散热器4的气流经过散热通道进入到电控盒1内部中，对电控盒1内部进行散热。
机壳20、风机组件、冷凝器50及控制组件10等的布置可以参考相关技术，此非本申请的重点，此处不再赘述。
控制器件包括控制板2以及设置在控制板2上的IPM、二极管、IGBT等若干电器件3，其中电器件3的类型、数量以及在控制板2上的排布均可根据相关技术及实际需求进行设置，本申请对此不做限制。
如图3所示，为方便控制器件在电控盒1内的安装，电控盒1包括可拆卸连接的盒体11和盒盖12，盒体11具有开口朝上的容纳空间，控制器件位于容纳空间内，且盒盖12盖设于容纳空间的开口处，以在方便控制器件的拆装的同时，提高对控制器件的保护。
盒体11与盒盖12的连接方式可以但不限于采用螺纹连接或卡接。盒体11与隔板60可拆卸连接，以提高电控盒1在隔板60上的拆装便利性。盒体11与隔板60的连接方式和连接结构可以参考相关技术，本申请对此不做限制。
盒体11具有朝向风机30的迎风侧壁1113，迎风侧壁1113上开设有通风通道，且迎风侧壁1113朝向风机30的一侧设置有散热器4。为方便描述，定义迎风侧壁1113的宽度方向为第一方向，迎风侧壁1113的高度方向为第二方向，迎风侧壁1113的壁厚方向为第三方向。通常，第一方向、第二方向及第三方向相互垂直。
如图3-图6所示，为方便散热器4和控制器件的安装，盒体11包括第一盒部111和设置在第一盒部111开口端的第二盒部112，第一盒部111具有开口朝上的容纳腔1111，且第一盒部111朝向风机30的一侧壁形成迎风侧壁1113。第二盒部112连接于第一盒部111的开口端，且第二盒部112沿迎风侧壁1113壁厚方向(朝向风机的方向)外凸于迎风侧壁1113。第二盒部112外凸于迎风侧 壁1113的部分和迎风侧壁1113之间形成有安装空间，散热器4位于安装空间内并与第二盒部112的底面可拆卸连接。
第二盒部112具有开口朝上的安装槽1121，安装槽1121沿第一方向的槽宽大致等于容纳腔1111沿第一方向的宽度，安装槽1121沿第三方向的槽长大于容纳腔1111沿第三方向的长度，容纳腔1111的开口贯通安装槽1121的槽底。控制板2安装于安装槽1121内，且控制板2上的部分电器件3伸入容纳腔1111中。
第一盒部111和第二盒部112的结构设置，使得第二盒部112在第三方向上的长度可以小于控制板2的长度，从而在实现控制板2安装的基础上，减小电控盒1的整体尺寸；同时，还能够使得第二盒部112和第一盒部111之间能够形成用于安装散热器4的空间，方便散热器4的安装，提高散热器4对电控盒1内控制器件的散热效果。
进一步地，安装槽1121的槽底对应散热器4的位置开设有散热口1122，散热口1122位于迎风侧壁1113的外侧，以使得气流能够直接并依次吹向散热口1122对应处的部分电路板以及电器件3，同时，安装槽1121中的热空气也可以直接通过散热器4散发，增强安装槽1121内部与电控盒1外部的气流交换，进一步提高控制器件的散热效果。
第一盒部111例如为六面体结构，以简化盒体11的加工。第一盒部111上开设有贯通内外空间的缺口1112，缺口1112至少贯通第二盒部112的底部，以方便控制器件与压缩机腔内部的压缩机连接。缺口1112贯通第一盒部111与迎风侧壁1113相对的一侧壁以及与迎风侧壁1113相邻且背离冷凝器50的一侧壁，以促进气流在第一盒部111内部的流动，进一步地提高散热的效果。
如图3和图7所示，在本实施例中，迎风侧壁1113上设置有通风格栅结构，通风格栅结构包括沿迎风侧壁1113的壁厚方向间隔设置的若干格栅层结构13，每个格栅层结构13均间隔设置有若干个通风口132，相邻两层格栅层结构13的通风口132在迎风侧壁1113外壁面的投影错位设置，最外层的格栅层结构13的通风口132连通电控盒1的外部空间，最内层的格栅层结构13的通风口132连通电控盒的容纳腔1111。
本实施例提供的电控盒1，通过沿迎风侧壁1113壁厚方向间隔设置的若干个格栅层结构13，且相邻格栅层结构13的通风口132错位设置，使得每个通风口132均通过相邻两层格栅层结构13之间的间隙与另一层的通风口132连通，从而使得每层格栅层结构13的通风口132以及相邻两层格栅层结构13之间的间隙共同形成连通电控盒1外部空间和内部腔体的通风通道，从而可以使得气流经过容纳腔1111内对控制器件散热，实现通风格栅结构的通风性；同时，由 于相邻格栅层结构13的通风口132错位设置，当气流由外层格栅层结构13的通风口132吹向相邻内层格栅层结构13时，大部分的气流首先与相邻内层格栅层结构13中的隔档结构接触，从而使得气流中携带的部分灰尘和水汽会附着在内层格栅层结构13的隔档结构上，从而减小气流将灰尘和水分携带入容纳腔1111的概率，在保证电控盒1的通风散热性能的同时，保证电控盒1的防水防尘性能，从而提高电控盒1的使用安全性。
在本实施例中，每个格栅层结构13均包括沿第一方向间隔设置的若干个通风口132，相邻两个格栅层结构13的通风口132在第一方向上错位设置，每个通风口132均沿第二方向延伸。由此能够增加每层栅格层结构的通风口132数量，提高排布规整性，方便加工，且在保证防水防尘性能的同时，提高电控盒1的通风散热性能；同时，该种设置，使得通风口132与散热器4的相邻两个翅片41之间的间隙正对设置，以减小风阻，提高气流从散热器4垂向通风口132的顺畅性，进一步地提高通风性能。
在其他实施例中，每个格栅层结构13中，通风口132也可以沿竖直方向(第二方向)间隔排布，且每个通风口132沿第一方向延伸，相邻两层的通风口132在第二方向上错位设置。
每个格栅层结构13均包括沿第一方向间隔设置的隔档部131，相邻两个隔档部131之间形成通风口132。相邻两层栅格层结构13的通风口132在第一方向上完全错位设置，且完全错位设置是指：相邻两层格栅层结构13的通风口132在迎风侧壁1113表面的投影不存在重合部分。该种设置，能够使得相邻两层栅格层结构13中，外层的通风口132与内层隔档部131正对设置，能够增大通过外层通风口132进入的气流与内层隔档部132碰撞的概率，从而增大灰尘和水汽附着在内层隔档部132上的概率，提高防尘防水性能。
在本实施例中，每一层的通风口132均与相邻一层的隔档部131一一正对设置，以简化加工，且更好地实现防水防尘性能与通风性能之间的平衡。
至少非最外层的隔档部131背离容纳腔1111的一面为平面或内凹面。当隔档部131的外表面(即隔档部131背离电控盒1容纳腔1111的一面)为平面时，当气流吹向隔档部131时，气流在与隔档部131接触后部分顺着隔档部131流向同层通风口132，部分气流沿背离容纳腔1111的方向反射，从而使得吹至隔档部131上的气流被打散，从而增大气流与隔档部131碰撞的次数和几率，增大灰尘和水汽被附着在隔档部131上的概率；同时，当气流吹向内层的隔档部131上时，气流被内层隔档部131打散散开后更容易与相邻外层的隔档部131碰撞，从而进一步地增加了气流与隔档部131接触的概率，从而提高了气流中携带的灰尘、水汽等在隔档部131上附着的概率。当隔档部131的外表面为内凹 面时，气流更加容易在内凹的凹槽中汇聚然后分散，在增大单个隔档部131与气流的接触面积的同时，进一步地增加对气流的打散程度，提高防尘的效果。
至少非最外层的格栅层结构13的隔档部131的外表面内凹形成有前凹槽1311，且前凹槽1311的开口正对相邻外层的通风口132设置。由此，当气流从外层通风口132吹向内层格栅层结构13时，气流首先沿垂直于格栅层结构13的方向吹入前凹槽1311内，吹入前凹槽1311内的气流沿着前凹槽1311的槽壁向相邻两层格栅层结构13之间的间隙中流动，且由于前凹槽1311槽壁沿远离容纳腔1111的方向延伸，使得气流向间隙流动的过程中具有沿远离容纳腔1111方向的分量，从而使得气流在流出前凹槽1311后，更容易撞击到相邻外层的隔档部131上，再被隔档部131反射至内层的通风口132处，由此能够进一步地增加气流在相邻两层隔档部131之间的碰撞，增大灰尘和气流被附着至隔档部131上的概率，从而进一步提高通风格栅结构的防水性能。
前凹槽1311在第一方向的开口宽度大于外层通风口132在第一方向的开口宽度，由此使得前凹槽1311沿第一方向的两侧槽壁的末端能够正对外层的相邻两个隔档部131设置，更加有利于引导从前凹槽1311流出的气流直接吹向相邻外层的隔档部131上。
进一步地，前凹槽1311的宽度沿朝向相邻外层通风口132的方向逐渐增大，由此能够使得前凹槽1311的槽壁能够由内至外倾斜地向靠近同层相邻的隔档部131延伸，从而在保证气流能够碰撞到相邻外层隔档部131的同时，气流能够顺畅地流出前凹槽1311，保证气流向前凹槽1311的侧部流动，保证气流由外至内流动的顺畅性和风量大小，保证电控盒1的通风散热性能。
在本实施例中，通风格栅结构包括内外两层格栅层结构13，位于外层的隔档部131的横截面积为矩形，以方便格栅层结构13的加工，位于内层的格栅层结构13的隔档部131为开口朝向外层通风口132的圆弧结构，以提高防尘防水效果，且保证通风效果。
在本实施例中，外层通风口132的宽度小于内层通风口132的宽度。该种设置，使得气流在经过外层通风口132时阻碍较小，从而能够允许更多的气流通过外层通风口132，而气流在流经内层格栅层结构13时阻挡较多，能够保证对灰尘和水分的阻挡效果，从而使得内层和外层格栅层结构13能够更好地配合保证通风性和防水性。
在本实施例中，格栅层结构13一体成型于迎风侧壁1113上，即格栅层结构13形成迎风侧壁1113的一部分，以简化安装。在其他实施例中，迎风侧壁1113上贯通开设有安装口，格栅层结构13可拆卸设置于安装口处，该种设置，可以简化迎风侧壁1113的加工。

通过在内层格栅层结构13的隔档部131上设置前凹槽1311，在外层隔档部131上设置后凹槽1313，当气流从内层前凹槽1311沿朝向相邻外层格栅层结构13扩散时，部分气流会流入相邻外层的相邻隔档部131的后凹槽1313中，从而增大气流在流经相邻两层格栅层结构13的间隙时与外层隔档部131的接触面积和碰撞概率，从而增大气流中携带的水汽和灰尘附着在隔档部131上的概率，从而能够在保证通风口132大小不变的情况下(即通风性不变的情况下)，增加通风格栅结构的防水防尘性能，从而提高电控盒1的防水防尘性能。
在本实施例中，通风格栅结构包括两层格栅层结构13，位于外层的隔档部131的横截面为开口朝向内层通风口132的U型结构，U型结构的U型槽形成隔档部131的后凹槽1313；位于内层的隔档部131为开口朝向外层通风口132的圆弧形结构。该种外层格栅层结构13和内层格栅层结构13的结构简单，易于加工，且容易控制通风口132的大小。
进一步地，外层隔档部131的U型结构的开口宽度基本等于底部宽度，以更好地引导气流通过外层的通风口132进入内层隔档部131的前凹槽1311中。 U型结构靠近同层通风口132的一侧壁朝向前凹槽1311，以使相邻两层的前凹槽1311和后凹槽1313在迎风侧壁1113的投影上重合，使得气流由前凹槽1311流向后凹槽1313更为顺畅。
