下面详细描述本发明的实施例， 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， 旨在用于解释本发明， 而不能理解为对本发明的限制。
下面参考图 1-图 11描述根据本发明实施例的制冷剂分配部件 100， 该制冷剂分配 部件 100 设在换热器的集流管内， 用于将制冷剂分配到集流管内， 从而制冷剂在换热 器的换热管之间均匀地分配。
如图 1-图 11所示， 根据本发明实施例的制冷剂分配部件 100包括本体 1， 本体 1内设 有沿本体 1的长度方向 （图 5中的左右方向） 延伸的分配腔 2， 分配腔 2的内侧壁 （图 1 中的上壁） 上设有多个分配孔 3。 这里可以理解的是， 分配腔 2 的横截面积的形状可以为 任何合适的形状， 例如为圆形、 弧形或矩形。 此外， 每个分配孔 3的大小、 形状、 位置和 开口方向可以根据具体应用设定， 优选地， 多个分配孔 3可以均匀地分布。 优选地， 分配 孔 3为狭槽的形式， 由此可以进一步提高制冷剂的分配均匀性。
根据本发明实施例的制冷剂分配部件 100，在多个分配孔 3中，从一部分分配孔 3喷出 的制冷剂与从另一部分分配孔 3喷出的制冷剂相互碰撞， 也可以描述为从一部分分配孔 3 喷出的制冷剂与从另一部分分配孔 3喷出的制冷剂相互对喷， 因此根据本发明实施例的制 冷剂分配部件 100可以实现制冷剂的对喷。
具体而言， 制冷剂进入到分配腔 2内并从多个分配孔 3喷出， 从一部分分配孔 3喷出 的制冷剂与从另一部分分配孔 3喷出的制冷剂相互碰撞， 换言之， 从一部分分配孔 3喷出 的制冷剂的运动路径和从另一部分分配孔 3喷出的制冷剂的运动路径相交， 从而汽液两相 的制冷剂在离开分配孔 3后出现汽液分离现象， 制冷剂碰撞后由于强烈的扰动作用， 两相 制冷剂会重新形成混合充分的汽液两相流， 从而减少进入到换热器的换热管内的两相制冷 剂出现汽液分离现象。
根据本发明实施例的制冷剂分配部件 100， 由于从一部分分配孔 3喷出的制冷剂与 从另一部分分配孔 3喷出的制冷剂相互碰撞， 相互碰撞的制冷剂由于强烈的扰动作用， 使得两相制冷剂混合均匀， 从而减少制冷剂出现汽液分离现象， 促使制冷剂更加均匀 的分配到换热管内， 提高了换热器中的制冷剂分配的均匀性， 从而提高换热器的换热 性能。
在本发明的一些实施例中， 分配孔 3分成多组， 例如， 每一组内的分配孔 3沿本 体 1 的长度方向成直线排列， 每一组内的分配孔 3也可以排列成其他形状。 从至少一 组分配孔 3喷出的制冷剂与从至少另一组分配孔 3喷出的制冷剂彼此碰撞， 也就是说， 多组分配孔 3中至少两组分配孔 3喷出的制冷剂彼此碰撞。 具体而言， 可以是一组分 配孔 3喷出的制冷剂与另一组分配孔 3喷出的制冷剂彼此碰撞，也可以是一组分配孔 3 喷出的制冷剂与其他组分配孔 3喷出的制冷剂相互碰撞， 还可以是几组分配孔 3喷出 的制冷剂与另几组分配孔 3喷出的制冷剂相互碰撞。 优选地， 从任意两组分配孔 3喷 出的制冷剂彼此碰撞， 从而可进一步提高两相制冷剂的混合均匀性。
根据本发明的一些实施例， 分配孔 3分成多组， 从任一组内的一部分分配孔 3喷 出的制冷剂与从该组内的另一部分分配孔 3 喷出的制冷剂彼此碰撞， 换言之， 每组分 配孔 3喷出的制冷剂可以彼此碰撞。
如图 1-图 1 1所示， 在本发明的一些具体实施例中， 本体 1具有弧形横截面， 从一 部分分配孔 3喷出的制冷剂与从另一部分分配孔 3喷出的制冷剂， 在以本体 1 的中心 为圆心且以本体 1 的半径为半径的圆内相互碰撞， 换言之， 从一部分分配孔 3喷出的 制冷剂与从另一部分分配孔 3 喷出的制冷剂在一个圆内相互碰撞， 上述圆的圆心为本 体 1 的中心， 上述圆的半径为本体 1的半径。 优选地， 如图 3中的箭头所示， 从一部 分分配孔 3喷出的制冷剂的运动轨迹和从另一部分分配孔 3喷出的制冷剂的运动轨迹 在上述圆的圆心处相交。
如图 1-图 11所示， 在本发明的一些实施例中， 分配腔 2包括多个分配通道 21， 多个分配通道 21沿本体 1的周向间隔开设置， 每个分配通道 21上均设有用于分配制 冷剂的分配孔 3。 优选地， 分配通道 21的形状和尺寸相同。
在本发明的一些实施例中， 每个分配通道 21的内侧壁上设有至少一排分配孔 3， 例如在图 1-3所示的实施例中， 本体 1 内设有三个沿本体 1 的长度方向延伸的分配通 道 21， 三个分配通道 21绕本体 1的周向均匀间隔分布， 分配通孔 21具有圆形横截面， 每个分配通道 21 的内侧壁向内凸出， 在每个分配通道 21 的内侧壁上设有一排成直线 排列的分配孔 3。 可以理解的是， 每个分配通道 21上可以形成对排分配孔， 并且每一 排内的分配孔可以绕分配通道 21的轴向螺旋分布。 优选地， 在图 1-3所示的示例中， 从三个分配通道 21的内侧壁上的分配孔 3分配出的制冷剂在本体 1的圆心处相交， 换 言之， 从三排分配孔 3喷出的制冷剂在本体 1的圆心处彼此碰撞。
如图 1-图 9所示， 在本发明的一些示例中， 本体 1具有弧形横截面， 分配通道 21 具有圆形横截面。 如图 2所示， 分配通道 21的中心到本体 1的圆心的距离为 L， 分配 通道 21的水利直径为 R，最外侧的两个分配通道 21上的分配孔 3的中心与本体 1的圆 心的连线之间的夹角为 α， 其中 2Narctan (R/L)〈a〈ii。 本申请的发明人发现， 通过满足 公式 2Narctan (R/L) < α < π , 可以使碰撞后的制冷剂更加顺利的流入到换热管中。
如图 10和图 11所示， 在本发明的另一些示例中， 本体 1具有弧形横截面， 分配通道 21具有弧形横截面， 本体 1的内侧壁和外侧壁均为弧形。 分配腔 2内设有两个隔筋 23以 将分配腔 2分隔成三个分配通道 21。
为了便于将本体 1设在集流管内， 如图 4-图 9所示， 本体 1的两端的内侧壁面上分别 设有周向凹槽 4， 两个隔板 5分别配合在两个周向凹槽 4内， 在制冷剂的流动方向上， 两 个隔板 5中位于上游的隔板 5上设有与分配通道 21适配的隔板孔 51， 两个隔板 5中位于 下游的隔板 5上可设有隔板孔 51也可以不设隔板孔 51。 两个隔板 5位于周向凹槽 4外的 部分的形状与集流管的内壁的形状适配， 以通过与集流管的内壁配合的隔板 5将本体 1固 定在集流管内。
如图 5所示， 位于上游 （左侧） 的隔板 5将集流管的内腔分隔成储液导流段 201和制 冷剂分配段 202， 制冷剂分配部件 100设在制冷剂分配段 202内， 分配腔 2与储液导流段 201连通。 制冷剂先进入到储液导流段 201内， 然后通过隔板 5上的隔板孔 51进入到多个 分配通道 21内， 制冷剂从每个分配通道 21的分配孔 3喷入到制冷剂分配段 202并在制冷 剂分配段 202内碰撞。
为了使制冷剂更容易的流入分配通道 21内，如图 9所示，在本发明的进一步实施例中， 周向凹槽 4与本体 1的左端面之间的分配通道的内侧壁被去除一部分， 从而让形成分配通 道开口段 22。 可以理解的是， 分配通道开口段 22位于储液导流段 201内。
下面参考图 3、 图 5和图 11描述根据本发明实施例的集流管组件。
如图 3、 图 5和图 11所示， 根据本发明实施例的集流管组件包括集流管 200和制冷剂 分配部件， 制冷剂分配部件设在集流管 200内， 制冷剂分配部件为参考上述实施例描述的 制冷剂分配部件 100。
优选地，制冷剂分配部件 100的本体 1的外侧壁面与集流管 200的内壁面贴合在一起， 本体 1的外侧壁面的形状与集流管 200的内壁面的形状适配以便于贴合。
根据本发明实施例的集流管组件，通过制冷剂分配部件 100，可以减少制冷剂出现汽液 分离现象， 提高制冷剂分配的均匀性， 进而提高换热器的换热性能。
下面参考图 12-图 17描述根据本发明另一实施例的集流管组件。 如图 12-图 17所示， 根据本发明实施例的集流管组件包括集流管 200和制冷剂分配部 件 100。

在本发明的具体示例中， 分配孔 3分成多组， 从任意两组分配孔 3喷出的制冷剂彼此 碰撞。
本体 1可通过焊接等方式固定在集流管 200内。
制冷剂进入到分配腔 2内， 从分配腔 2喷入到混合腔 6内， 从一部分分配孔 3喷出的 制冷剂的运动路径和从另一部分分配孔 3喷出的制冷剂的运动路径存在相交点以在混合腔 6 内相互碰撞， 从而即使汽液两相的制冷剂在离开分配孔 3后出现汽液分离现象， 制冷剂 碰撞后由于强烈的扰动作用， 两相制冷剂重新形成混合充分的汽液两相流， 减少进入到换 热器的换热管 300内的两相制冷剂出现汽液分离现象。
制冷剂可以在集流管 200的径向方向上进行相互碰撞， 制冷剂也可以在集流管 200的 轴向方向上进行相互碰撞，制冷剂还可以在集流管 200的轴向及径向上同时进行相互碰撞， 甚至于制冷剂可以偏离轴向和径向的预定角度上相互碰撞。
根据本发明实施例的集流管组件， 由于从一部分分配孔 3喷出的制冷剂与从另一部分 分配孔 3喷出的制冷剂在混合腔 6内相互碰撞， 相互碰撞的制冷剂由于强烈的扰动作用， 使得两相制冷剂混合均匀， 从而减少制冷剂出现汽液分离现象， 促使制冷剂更加均匀 的分配到换热管 300 内， 提高了换热器中的制冷剂分配的均匀性， 从而提高换热器的 换热性能。
