下面参考附图描述根据本申请实施例的冰箱1。
如图1-图6所示，根据本申请实施例的冰箱1包括箱胆100、风道200和换热器。具体而言，所述换热器可以为蒸发器300。
风道200设在箱胆100内且与箱胆100共同限定出换热腔。所述换热器设在所述换热腔内，箱胆100和风道200中的至少一个上设有导流筋，所述导流筋位于所在箱胆100和/或风道200与所述换热器之间以用于对所在箱胆100和/或风道200与所述换热器之间的气流进行导向。换言之，所述导流筋设在箱胆100上且位于箱胆100与所述换热器之间；或所述导流筋设在风道200上且位于风道200与所述换热器之间；或风道200和箱胆100上均设有所述导流筋，风道200上的所述导流筋位于风道200与所述换热器之间，箱胆100上的所述导流筋位于箱胆100与所述换热器 之间。
根据本申请实施例的冰箱1，通过设置所述导流筋，可以利用所述导流筋对经过所述换热器与箱胆100和/或风道200之间的气流进行导向，相比相关技术中的冰箱，可以使气流在所述导流筋的导向下产生区别于原有流向的分流，从而避免气流在所述换热器与箱胆100和/或风道200之间进行整体规则的流动而产生阻碍换热的热边界层，使所述换热器能够充分与流过的气流进行换热，提高所述换热器的换热效果，以进一步提高冰箱的制冷效果。
并且，通过设置所述导流筋，可以利用所述导流筋对气流产生朝向所述换热器方向的扰动，相比相关技术中的冰箱，可以使气流产生垂直于原有方向且朝向所述换热器的乱流，从而进一步避免气流整体规则移动而产生阻碍换热的热边界层，进一步提高所述换热器的换热效果。
此外，通过在箱胆100和/或风道200上设置所述导流筋，可以利用所述导流筋对所在的箱胆100和/或风道200进行加强，从而提高箱胆100和/或风道200的结构强度和刚度，保证冰箱1的可靠性。
进一步地，由于所述导流筋位于所述换热器与所在箱胆100和/或风道200之间，可以利用所述导流筋对所述换热器进行一定程度的限位，从而提高对所述换热器的安装精度的容差。这样不仅可以在安装时便于将所述换热器顺利装入所述换热腔，而且可以在安装后保证所述换热器的结构稳定性和可靠性。
因此，根据本申请实施例的冰箱1具有制冷效果好、可靠性高等优点。
下面参考附图描述根据本申请具体实施例的冰箱1。
在本申请的一些具体实施例中，如图1-图6所示，根据本申请实施例的冰箱1包括箱胆100、风道200和所述换热器。
所述导流筋包括上导流筋110和下导流筋210(上下方向如图中的箭头所示，上下方向仅为了便于表述，并非对于本申请实际设置方向的限定)。上导流筋110设在箱胆100上且位于箱胆100与所述换热器的上表面之间。下导流筋210设在风道200上且位于风道200与所述换热器的下表面之间。这样可以同时利用上下两个所述导流筋对所述换热器上方和下方的气流进行导向和扰动，从而避免所述换热器的上方和下方产生热边界层，提高所述换热器的换热效果。
此外，可以利用上导流筋110和下导流筋210分别对箱胆100和风道200进行加强，利用上导流筋110和下导流筋210同时对所述换热器进行限位，提高冰箱1结构的稳定性和可靠性。
可选地，上导流筋110一体形成在箱胆100上，下导流筋210一体形成在风道200上。具体而言，所述导流筋可以通过注塑形成在箱胆100和/或风道200上。这样可以简化所述导流筋的装配过程，提高所述导流筋的可靠性。
有利地，如图1-图6所示，所述导流筋的中心轴线为光滑曲线。这里需要理解的是，所述导流筋的中心轴线指沿所述导流筋的延伸方向定向的中心轴线。这样可以使所述导流筋对气流的导向效果更加平滑，避免产生对气流产生较大阻力的区域，保证冰箱1的送风风量。
具体地，如图1-图6所示，所述换热器为翅片式换热器，所述导流筋以所述换热器在平行于所述换热器的翅片的长度方向的中心线为轴轴对称。具体而言，该对称轴沿前后方向定向(前后方向如图中的箭头所示，前后方向仅为了便于表述，并非对于本申请实际设置方向的限定)。这样可以使所述导流筋产生左右均匀的导流效果，避免出现所述换热器两侧风量不均的情况，从而进一步提高所述换热器的换热的均匀性，进一步提高所述换热器的换热效果。
更为具体地，如图1-图6所示，所述导流筋包括相互轴对称的两个对称肢111，每个对称肢111的中心轴线为通过四点控制的样条曲线。这样使所述导流筋的导流效果更加灵活多样，便于所述导流筋实现不同的导流效果，从而进一步便于提高所述换热器的换热效果。
进一步地，如图6所示，每个对称肢111的中心轴线为通过依次排列的第一控制点P1、第二控制点P2、第三控制点P3和第四控制点P4控制的样条曲线，第四控制点P4位于所在对称肢111与另一对称肢111相连的一端，第一控制点P1位于对称肢111的另一端，第二控制点P2相对第一控制点P1和第四控制点P4的假想连线向后偏移，第三控制点P3相对第一控制点P1和第四控制点P4的假想连线向前偏移，经过所述换热器的气流从所述换热器的前端流动至所述换热器的后端。这样可以进一步提高所述导流筋的灵活性，从而可以便于对所述导流筋的实际形状进行控制。
图6示出了根据本申请一个具体示例的冰箱1。如图6所示，经过所述换热器的气流从所述换热器的前端流动至所述换热器的后端，所述导流筋的两端分别邻近所述换热器的左后端和右后端设置，所述导流筋的中心处邻近所述换热器的前边沿的中心处设置。这样可以使所述导流筋的导流效果能够尽量覆盖所述换热器的整体，避免产生导流不到的区域，从而进一步提高所述换热器的换热效果，同时可以使从前方流向所述换热器的气流产生向左和向右的分流，使所述换热器的左右两侧得到均匀的导流效果，提高所述换热器的换热均匀性，提高所述换热器的换热效果。
具体地，所述导流筋止抵在所述换热器上。具体而言，上导流筋110止抵在所述换热器的上表面上，下导流筋210止抵在所述换热器的下表面上。更为具体地，上导流筋110止抵在所述换热器的翅片的上边沿，下导流筋210止抵在所述换热器的翅片的下边沿。这样可以提高上导流筋110和下导流筋210对所述换热器的定位效果，从而进一步提高所述换热器的稳定性和可靠性，进一步便于所述换热器的装配。
下面描述根据本申请实施例的冰箱的箱胆。根据本申请实施例的冰箱的箱胆朝向 所述冰箱的换热器的表面设有用于对所述箱胆和所述换热器之间的气流进行导向的导流筋。
根据本申请实施例的冰箱的箱胆，能够提高冰箱的制冷效果，具有可靠性强等优点。
下面描述根据本申请实施例的冰箱的风道。根据本申请实施例的冰箱的风道朝向所述冰箱的换热器的表面设有用于对所述风道和所述换热器之间的气流进行导向的导流筋。
根据本申请实施例的冰箱的风道，能够提高冰箱的制冷效果，具有可靠性强等优点。
下面参考图6描述根据本申请实施例的冰箱的导流筋的设计方法，包括以下步骤：
A)在所述导流筋的中心轴线所在平面建立直角坐标系，使用多个控制点控制样条曲线形状；
B)将控制点坐标值作为变量，以换热器最大换热量为目标，使用计算流体动力学仿真寻优最佳型线；
C)变量使用超拉丁方设计方法设计数值实验；
D)搭建寻优流程找到最佳曲线型线。
根据本申请实施例的冰箱的导流筋的设计方法，通过采用模拟仿真的方式，能够得到最理想的导流筋的线型，从而进一步提高冰箱1的制冷效果。
具体而言，在步骤A中，使用4个控制点：P1(x1,y1)，P2(x2,y2)，P3(x3,y3)，P4(x4,y4)控制对称肢111的中心轴线的线型。
在步骤B中，设所述换热器宽度为W，高度为H，将P1-P4控制点坐标值作为变量，共计8个变量，使用计算流体动力学仿真寻优最佳型线；其中变量约束条件为：d<x1<x2<x3<x4<(W+d)，0<y1<y2<y3<y4<H，优化目标为换热器最大换热量。
换言之，根据本申请一个具体实施例的冰箱1的导流筋的设计方法，包括以下步骤：
A)在所述导流筋的中心轴线所在平面建立直角坐标系，使用4个控制点：P1(x1,y1)，P2(x2,y2)，P3(x3,y3)，P4(x4,y4)控制其中一个对称肢111的中心轴线的线型。
B)设所述换热器宽度为W，高度为H，将P1-P4控制点坐标值作为变量，共计8个变量，使用计算流体动力学(CFD)仿真寻优最佳型线；其中变量约束条件为：d<x1<x2<x3<x4<(W+d)，0<y1<y2<y3<y4<H；优化目标为蒸发器最大换热量，在本实施例中W＝250mm，H＝190mm；
C)8个变量使用超拉丁方设计方法设计数值实验，实际生成81个样本；
D)CFD仿真使用三维仿真，考虑对称简化计算模型；搭建寻优流程找到最佳曲线型线。
最终根据对称图形特性，得到另一对称肢111的形状，从而得到完整的导流筋的线型。
