具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考图1-图8描述根据本申请实施例的电控盒100。电控盒100可以应用于空调室外机200例如变频空调室外机，以控制压缩机的运行频率。在本申请下面的描述中，以电控盒100应用于变频空调室外机为例进行说明。当然，本领域技术人员可以理解，电控盒100还可以应用于定频空调室外机。
如图1-图7所示，根据本申请第一方面实施例的电控盒100，包括电控盒基座1、散热器2和扰流件3。
电控盒基座1上设有电控元器件10。散热器2设在电控盒基座1上，散热器2包括间隔设置的多个散热片21。例如，在图2-图4的示例中，散热器2的多个散热片21沿散热片21的厚度方向依次间隔设置，每相邻两个散热片21之间限定出一个风道。散热片21用于对电控盒100内的核心电控元器件10进行散热，保证其在高温工况下稳定运行。具体地，散热器2可以与电控元器件10例如大功率发热元器件表面接触。当电控元器件10工作时，电控元器件10会产生大量的热量，这些热量会传递给散热器2的多个散热片21，而流经多个散热片21的气流可以将多个散热片21上的热量带走， 以达到降低电控元器件10温度的目的。其中，散热器2可以布置在电控盒基座1的端部，并通过螺钉等固定在电控盒基座1上。
多个扰流件3间隔设置在电控盒基座1上，且多个扰流件3均位于散热器2和电控元器件10之间，且每个扰流件3在沿散热片21的长度方向上的中心轴线位于相邻两个散热片21之间。例如，参照图2，多个扰流件3在散热片21的厚度方向上依次间隔设置，多个扰流件3和散热器2在气流的流动方向上依次设置，且多个扰流件3位于散热器2的上游，在散热片21的长度方向上、每个扰流件3的中心轴线位于相邻两个散热片21之间。这里，需要说明的是，“上游”可以理解为在气流的流动方向上的上游。
在本申请的描述中，“多个”的含义是两个或两个以上。
气流例如空气等在流过散热器2的过程中，会在散热器2表面形成较薄的热边界层和速度边界层，在热边界层内，温度沿散热器2表面法线方向(即与气流方向垂直的方向)变化，在热边界层外(即离开散热器2表面一定距离)温度基本不变化；在速度边界层内，速度沿散热器2表面法线方向(即与气流方向垂直的方向)变化，在速度边界层外(即离开散热器2表面一定距离)速度基本不再变化，紊流对流换热层主要是层流底层，由于底层极薄，温度梯度大，紊流换热强度比层流强。气流例如空气等在通过电控盒100内部流到散热器2的过程中，需要先经过多个扰流件3，气流例如空气等在扰流件3的作用下，使得进入到散热片21表面的流体状态为紊流状态，能够显著提高换热效率，提高换热效果，从而可以很好地对电控盒100内的电控元器件10进行散热，降低电控元器件10的温度。
根据本申请实施例的电控盒100，通过设置上述的多个扰流件3，提高了换热效率，从而能够更加有效地降低电控盒100上电控元器件10的温度。当散热器2应用于空调室外机200例如变频空调室外机时，可以很好地对电控盒100内的电控元器件10进行散热，从而不易出现电控元器件10损坏或压缩机限频而使压缩机无法正常运行导致影响空调器制冷效果的问题，提升了用户体验。
根据本申请的一些实施例，参照图1-图4并结合图5，每个扰流件3形成为长条形结构。由此，通过将扰流件3设置成长条形结构，在保证对流经其的气流起到很好的扰动作用的同时，扰流件3的体积较小，从而可以减小电控盒100的占用空间。当然，每个扰流件3还可以形成为片状结构，例如，每个扰流件3可以与散热片21大致平行并沿图2中所示的左右方向延伸。由此，同样可以起到扰动气流的作用。
可选地，当每个扰流件3形成为长条形结构时，每个扰流件3沿竖直方向延伸，如图2所示。例如，在图2的示例中，长条形的扰流件3竖直向上延伸。由此，可以进一 步减小电控盒100的占用空间。
根据本申请的进一步实施例，参照图3并结合图4，每个扰流件3的厚度小于相邻两个散热片21之间的距离。由此，通过设置使每个扰流件3的厚度小于相邻两个散热片21之间的距离，从而流过扰流件3后的气流可以顺畅地进入到多个散热片21限定出的风道内，而不会影响散热。
可选地，每个扰流件3的厚度为t，其中t满足：1mm≤t≤3mm，如图6和图7所示。由此，如果将扰流件3的厚度t设置为小于1mm，则扰流件3的厚度相对较小，可能出现未将流道散热器2表面的空气状态变为紊流状态的情况，从而散热效果相对较差；如果将扰流件3的厚度t设置为大于3mm，则扰流件3的厚度相对较大，可能出现气流不能顺畅通过散热器2，从而会影响散热效果。也就是说，通过设置使每个扰流件3的厚度t满足1mm≤t≤3mm，在保证进入散热器2的气流状态为紊流状态的同时，使气流可以顺畅地通过散热器2，从而有效地保证了散热效果。进一步可选地，t进一步满足：t＝2mm。
根据本申请的一些可选实施例，参照图6和图7，每个扰流件3的高度为h，每个散热片21的高度为H，其中h、H满足：0＜h/H≤1/2。由此，当h、H满足h/H＞1/2时，在理论上，能很好地保证进入散热器2的气流状态为紊流状态，但在实际加工时并不易加工出上述的扰流件3。换言之，通过设置使h、H满足0＜h/H≤1/2，在保证进入散热器2的气流状态为紊流状态的同时，方便了扰流件3的加工。例如，扰流件3可以与电控盒基座1一体成型。进一步地，h、H进一步满足：h/H＝1/4或2/5。
在本申请的描述中，需要理解的是，术语“中心”、“长度”、“宽度”、“厚度”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
根据本申请的一些实施例，相邻两个扰流件3之间的距离与相邻两个散热片21之间的距离相等。由此，方便了多个扰流件3和多个散热片21的布置。进一步地，参照图3和图4，在散热片21的厚度方向上，每个扰流件3可以位于相邻两个散热片21的中央，此时每个扰流件3与相邻两个散热片21之间的距离相等；当然，每个扰流件3在顺气流方向上的中心轴线还可以偏离相邻两个散热片21之间的中心平面。
可选地，扰流件3的数量比散热片21的数量少1个，如图3所示。此时在顺气流方向上，每相邻两个散热片21之间均有一个扰流件3。由此，可以进一步提高换热效 率。
可选地，参照图2和图3，每个扰流件3与每个散热片21平行。由此，在保证散热效果的同时，使得整个电控盒100的结构简单，易于加工。
根据本申请的一些实施例，扰流件3与散热片21之间的夹角为θ，其中θ满足：0°≤θ≤30°。由此，通过设置使扰流件3与散热片21之间的夹角θ满足0°≤θ≤30°，在保证提升换热效率的情况下，降低了扰流件3和散热片21的加工难度，从而降低了成本。例如，在图1-图6的示例中，扰流件3与散热片21之间的夹角θ＝0°。当然，本申请不限于此，例如，在图7的示例中，每个扰流件3相对于散热片21倾斜设置，此时每个扰流件3与散热片21之间的夹角θ≠0°。
可选地，每个扰流件3为阻燃材料件。由此，通过采用阻燃材料作为扰流件3，在保证散热效果的同时，提升了电控盒100的使用安全性。例如，每个扰流件3为金属件、塑料件或玻璃件等。但不限于此。
进一步地，如图2和图3所示，电控盒基座1上设有护板11，护板11可以通过螺钉等固定在电控盒基座1上，护板11用于保护电控盒100内的元器件例如电控元器件10等。多个扰流件3位于护板11和散热器2之间。可选地，护板11为钣金件等。
根据本申请实施例的电控盒100，通过在电控盒100风道和散热器2风道之间设置多个扰流件3，当空气由压缩机侧通过电控盒100风道流到散热器2时，在散热器2表面的流场中加入紊流，换热效率更高，能够更加有效地降低电控元器件10的温度。
如图8所示，根据本申请第二方面实施例的空调室外机200，包括根据本申请上述第一方面实施例的电控盒100。其中，电控盒100可以设在空调室外机200例如变频空调室外机内的顶部。
根据本申请实施例的空调室外机200例如变频空调室外机，通过采用上述的电控盒100，提升了空调室外机200例如变频空调室外机的整体性能。
根据本申请实施例的电控盒100和空调室外机200的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱 离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
