为实现所述目的的空调模块，包括壳体和传感器；所述壳体允许第一气流和第二气流通过；所述传感器的检测头设置在所述壳体内；所述壳体内设置有气流混合装置；沿所述第一气流和所述第二气流的流动方向，所述气流混合装置设置在所述传感器的检测头的上游，并用于使所述第一气流和所述第二气流混合，从而使所述传感器的检测头能够检测所述第一气流和所述第二气流混合后的气流的温度。

附图说明
本实用新型的上述的以及其他的特征、性质和优势将通过下面结合附图和实施例的描述而变得更加明显，其中：
图1为空调模块的示意图；
图2为空调模块的俯视图；
图3为空调模块沿A-A方向剖开后的示意图；

具体实施方式
下述公开了多种不同的实施的主题技术方案的实施方式或者实施例。为简化公开内容，下面描述了各元件和排列的具体实例，当然，这些仅仅为例子而已，并非是对本实用新型的保护范围进行限制。例如在说明书中随后记载的第一特征在第二特征分布，可以包括第一和第二特征通过直接联系的方式分布的实施方式，也可包括在第一和第二特征之间形成附加特征的实施方式，从而第一和第二特征之间可以不直接联系。另外，这些内容中可能会在不同的例子中重复附图标记和/或字母。该重复是为了简要和清楚，其本身不表示要讨论的各实施方式和/或结构间的关系。进一步地，当第一元件是用与第二元件相连或结合的方式描述的，该说明包括第一和第二元件直接相连或彼此结合的实施方式，也包括采用一个或多个其他介入元件加入使第一和第二元件间接地相连或彼此结合。
需要注意的是，图1至图5均仅作为示例，其并非是按照等比例的条件绘制的，并且不应该以此作为对本实用新型实际要求的保护范围构成限制。
图1、2、3、4、5示出了本实用新型一个实施例中的空调模块900，包括壳体1以及设置在壳体1上的传感器2，其中，壳体1具有气流入口1a和气流出口1b。空气能够从气流入口1a进入壳体1，并从气流出口1b流出壳体1。如图5所示，传感器2具有检测头2a，检测头2a设置在壳体1内，以检测气流的温度。
继续参考图3、4，通过壳体1的气流根据在壳体1内位置的不同可以分为第一气流F1和第二气流F2。由于在壳体1内位置的不同，第一气流F1和第二气流F2可能会具有不同的温度。在朝向气流出口1b流动的过程中，第一气流F1和第二气流F2会逐步混合，越发靠近气流出口1b，二者的混合程度就越均匀。但由于传感器2在壳体1上的安装位置存在限制，传感器2在安装完毕后会过多地被第一气流F1或第二气流F2吹拂，这导致传感器2所检测到的气流温度与气流出口1b的气流温度存在人们所不期望的差异。
为使第一气流F1和第二气流F2在吹拂传感器2时已经混合，壳体1内设置有气流混合装置3。气流混合装置3设置在传感器2的检测头2a的上游，并用于使第一气流F1和第二气流F2混合，从而使传感器2的检测头2a能够检测第一气流F1和第二气流F2混合后的气流FM的温度。混合后的气流FM的温度与气流出口1b的气流温度相比具有 更小的差异，从而使得传感器所检测到的气流的温度与气流出口处的气流的温度一致性较高。
如图3所示，第一气流F1和第二气流F2的流动方向D为气流入口1a指向气流出口1b的方向。
在一个未图示的实施例中，气流混合装置3包括风扇装置。风扇装置可以具有动力源，从而使得风扇装置能够对第一气流F1和第二气流F2进行主动混合搅拌，从而使第一气流F1和第二气流F2混合。风扇装置也可以不具有动力源，第一气流F1和第二气流F2通过风扇装置时，能推动风扇装置转动，并实现第一气流F1和第二气流F2混合的技术效果。
如图4所示，气流混合装置3包括导流筋30；导流筋30用于引导第一气流F1朝向第二气流F2偏转，以使第一气流F1和第二气流F2能够混合。其中，导流筋30的数量可以为多个且大致平行布置。
继续参考图4，导流筋30包括第一导流筋301和第二导流筋302；第一导流筋301用于引导第一气流F1朝向第二气流F2偏转，第二导流筋302用于引导第二气流F2朝向第一气流F1偏转。这一设计有助于提高导流筋30引导气流的效率。
导流筋30还包括中间导流筋300；中间导流筋300与第一导流筋301限定第一气流F1的流动通道，即第一气流F1在中间导流筋300与第一导流筋301之间流动。中间导流筋300相对于第二导流筋302更加靠近第一导流筋301而设置。
如图5所示，壳体1具有安装壁10；导流筋30和传感器2均安装在安装壁10上。
在一个实施例中，如图5所示，导流筋30在安装壁10上的高度H1大于或者等于检测头2a在安装壁10上的高度H2。这一设计有助于提高导流筋30引导气流的效率。
在另一个未图示的实施例中，导流筋30在安装壁10上的高度H1大于检测头2a在安装壁10上的高度H2的二分之一，并小于检测头2a在安装壁10上的高度H2。这一设计给出了导流筋30在安装壁10上的高度H1的下限，即大于检测头2a在安装壁10上的高度H2的二分之一。
如图4所示，壳体1具有分隔板11；分隔板11在壳体1内分隔出第一气流通道100和第二气流通道200；一个气流混合装置3和一个传感器2设置在第一气流通道100内；和/或另一个气流混合装置3和另一个传感器2设置在第二气流通道200内。
本实用新型虽然以较佳实施例公开如上，但其并不是用来限定本实用新型，任何本领域技术人员在不脱离本实用新型的精神和范围内，都可以做出可能的变动和修改，凡是未脱离本实用新型技术方案的内容，依据本实用新型的技术实质对以上实施例所作的任何修改、等同变化及修饰，均落入本实用新型权利要求所界定的保护范围之内。
