下面参照图1至图7描述根据本公开一些实施例的分离装置100、换热器200和制冷设备。
如图1、图2、图3和图4所示，本公开的一些实施例中提出了一种分离装置100，用于换热器200，分离装置100包括分离部110和封板140。
分离部110设置有分离腔134、入口114和分离口116，入口114和分离口116均与分离腔134连通。
封板140与分离部110连接，且位于分离部110的一侧，封板140能够连接换热器的壳体210。
详细地，分离装置100包括分离部110和封板140。封板140与分离部110连接，且封板140位于分离部110的一侧。分离装置100置于换热器的壳体210内，封板140与换热器的壳体210连接，封板140与换热器的壳体210之间形成腔室240，换热器200的回气口230与该腔室240连通，冷媒通过回气口230被抽吸进入腔室240内，冷媒进入腔室240内后与封板140发生第一次撞击，冷媒中的液体由于撞击而被分离出来。
第一次撞击后，气态冷媒绕过封板140流向分离部110，而后通过分离部110的入口114进入分离腔134，冷媒流入分离腔134会与分离腔134的腔壁发生第二次撞击，而后由分离部110的分离口116流出分离装置100，并通过换热器200的出口212吸入压缩机的吸气口。
该设置使得冷媒流经分离装置100时，冷媒与分离装置100经过多次撞击，能够有效分离出冷媒中的液体，能够大大减小吸入压缩机的冷媒中的液体，降低冷媒中的液体对压缩机的损害，有利于提升制冷设备的制冷效率，及有利于提升产品使用的安全性及可靠性。
具体地，分离口116的过流截面形状包括以下任一种：圆形、多边形及异形，异形指的是形状不规则的形状，多边形包括三角形、四边形、五边形等等，在此不一一列举。
具体地，入口114的过流截面形状包括以下任一种：圆形、多边形及异形，异形指的是形状不规则的形状，多边形包括三角形、四边形、五边形等等，在此不一一列举。
如图1、图2、图3和图4所示，本公开的一些实施例提供了一种分离装置100，用于换热器200，分离装置100包括分离部110和封板140。
分离部110设置有分离腔134、入口114和分离口116，入口114和分离口116均与分离腔134连通。
封板140与分离部110连接，且位于分离部110的一侧，封板140能够连接换热器的壳体210。
进一步地，如图3和图7所示，封板140的外边缘的至少一部分凸伸出分离部110的外表面，封板140的外边缘能够连接换热器的壳体210。
详细地，通过合理设置封板140和分离部110的配合结构，使得封板 140的外边缘的至少一部分凸伸出分离部110的外表面，封板140的外边缘能够连接换热器的壳体210。也即，封板140凸伸出分离部110的外表面的部分能够与壳体连接。该设置在保证分离装置100与壳体装配的有效性及可行性的同时，使得分离部110与壳体的内表面之间具有间隙，也即，保证分离部110的分离口116与换热器200的出口212之间具有容置冷媒的空间，为压缩机有效吸入冷媒提供了结构支撑。
沿分离部110背离封板140的一侧至封板140的方向，分离部110在封板140上的投影位于封板140的边缘之内。
如图1、图2、图3和图4所示，本公开的一些实施例提供了一种分离装置100，用于换热器200，分离装置100包括分离部110和封板140。
分离部110设置有分离腔134、入口114和分离口116，入口114和分离口116均与分离腔134连通。
封板140与分离部110连接，且位于分离部110的一侧，封板140能够连接换热器的壳体210。
进一步地，图2、图3、图4、图5和图6所示，分离部110包括顶壁118和侧壁122。
侧壁122的第一端连接顶壁118，侧壁122的第二端合围出入口114，第一端与第二端对应设置，分离口116设于侧壁122。
其中，封板140连接顶壁118和侧壁122。
详细地，分离部110包括顶壁118和侧壁122，侧壁122具有第一端和第二端，第一端和第二端相对且间隔布置，侧壁122的第一端连接顶壁118，侧壁122的第二端合围出入口114。
也即，第一次撞击后，气态冷媒绕过封板140流向分离部110，而后通过分离部110底部的入口114进入分离腔134，冷媒流入分离腔134会与分离腔134的腔壁发生第二次撞击，而后由分离部110侧壁122的分离口116流出分离装置100，并通过换热器200的出口212吸入压缩机的吸气口。
该设置延长了冷媒在分离部110内的流动路径，有利于增加冷媒与分离腔134的腔壁的碰撞频次，进而有利于有效分离出冷媒中的液体，提升 了冷媒的气液分离的有效性及高效性。
可以理解的是，封板140连接顶壁118和侧壁122，封板140既与分离部110的顶壁118连接，又与分离部110的侧壁122连接。
具体地，分离部110的顶壁118和侧壁122合围出凹槽结构。
进一步地，如图3所示，侧壁122包括第一子侧壁124和第二子侧壁126。
第一子侧壁124连接于顶壁118的第一侧。
第二子侧壁126连接于顶壁118的第二侧，第一子侧壁124和第二子侧壁126对应设置。
分离口116的数量为多个，多个分离口116中的一部分分离口116设于第一子侧壁124，另一部分分离口116设于第二子侧壁126。
其中，侧壁122包括第一子侧壁124和第二子侧壁126，第一子侧壁124和第二子侧壁126对应设置，第一子侧壁124和第二子侧壁126均与顶壁118连接，也即，第一子侧壁124和第二子侧壁126位于顶壁118的相对两侧。
分离口116的数量为多个，对多个分离口116进行划分，一部分分离口116设于第一子侧壁124，另一部分分离口116设于第二子侧壁126。这样，冷媒可由第一子侧壁124和第二子侧壁126同时流出分离部110。该设置增大了分离口116的总面积，增大了分离口116的分布角度，可保证压缩机的吸气量，为保证产品的工作效率提供了有效且可靠的结构支撑。
具体地，分离部110的顶壁118未设置有分离口116，故而，冷媒进入分离腔134后，冷媒能够与分离腔134的顶壁118第二次撞击，而后流向位于侧壁122的分离口116以发生第三次撞击，该设置能够增多冷媒与分离腔134的腔壁的碰撞频次，有利于提升气液分离的有效性。
如图1、图2、图3和图4所示，本公开的一些实施例提供了一种分离装置100，用于换热器200，分离装置100包括分离部110和封板140。
分离部110设置有分离腔134、入口114和分离口116，入口114和分离口116均与分离腔134连通。
封板140与分离部110连接，且位于分离部110的一侧，封板140能 够连接换热器的壳体210。
分离部110包括顶壁118和侧壁122。
侧壁122的第一端连接顶壁118，侧壁122的第二端合围出入口114，第一端与第二端对应设置，分离口116设于侧壁122。
其中，封板140连接顶壁118和侧壁122。
进一步地，分离部110的顶壁118相较于入口114更靠近换热器200的出口212。
详细地，通过合理设置分离部110与换热器200的出口212的位置关系，使得分离部110的顶壁118相较于入口114更靠近换热器200的出口212，也即，分离部110的顶壁118位于入口114和换热器200的出口212之间。该设置限定了分离部110的入口114、顶壁118和换热器200的出口212的位置关系，使得绕过封板140的冷媒通过入口114流入分离器提供了有效且可靠的结构支撑。
如图1、图2、图3和图4所示，本公开的一些实施例提供了一种分离装置100，用于换热器200，分离装置100包括分离部110和封板140。
分离部110设置有分离腔134、入口114和分离口116，入口114和分离口116均与分离腔134连通。
封板140与分离部110连接，且位于分离部110的一侧，封板140能够连接换热器的壳体210。
分离部110包括顶壁118和侧壁122。
侧壁122的第一端连接顶壁118，侧壁122的第二端合围出入口114，第一端与第二端对应设置，分离口116设于侧壁122。
其中，封板140连接顶壁118和侧壁122。
进一步地，如图2和图3所示，分离部110的侧壁122包括第一区域128和第二区域130。
第一区域128相较于第二区域130更靠近换热器200的出口212，分离口116设于第二区域130。
详细地，分离部110的侧壁122包括第一区域128和第二区域130，第一区域128靠近换热器200的出口212，第二区域130远离换热器200 的出口212。通过合理设置第一区域128、第二区域130和分离口116的配合结构，使得分离口116设于第二区域130。该设置能够延长冷媒在分离腔134内的流动路径，增加冷媒与分离腔134的腔壁的碰撞频次，提升分离效果。
若第一区域128设置有分离口116，则，分离腔134内的大部分冷媒会通过第一区域128的分离口116被压缩机直接吸走，这样，会大大降低冷媒与分离腔134的腔壁的碰撞频次，这样，分离液体的效果较差，易造成吸气带液。
进一步地，如图2和图3所示，第二区域130的数量为两个，第一区域128位于两个第二区域130之间。
其中，第二区域130的数量为两个，通过合理设置两个第二区域130和第一区域128的位置关系，使得第一区域128位于两个第二区域130之间，该设置在保证冷媒与分离腔134的腔壁的充分碰撞的同时，有利于增大分离口116的总面积，进而有利于保证压缩机的吸气量。
如图1、图2、图3和图4所示，本公开的一些实施例提供了一种分离装置100，用于换热器200，分离装置100包括分离部110和封板140。
分离部110设置有分离腔134、入口114和分离口116，入口114和分离口116均与分离腔134连通。
封板140与分离部110连接，且位于分离部110的一侧，封板140能够连接换热器的壳体210。
分离部110包括顶壁118和侧壁122。
侧壁122的第一端连接顶壁118，侧壁122的第二端合围出入口114，第一端与第二端对应设置，分离口116设于侧壁122。
其中，封板140连接顶壁118和侧壁122。
进一步地，如图4和图6所示，顶壁118和侧壁122的连接处至换热器的壳体210的最小距离记作第一距离L1，入口114至顶壁118的距离记作第二距离L2；第一距离L1大于等于第二距离L2。
详细地，进一步限定流分离部110的顶壁118、侧壁122、入口114和换热器的壳体210的配合结构，使得顶壁118和侧壁122的连接处至换热 器的壳体210的最小距离为第一距离L1，入口114至顶壁118的距离为第二距离L2，并使第一距离L1大于等于第二距离L2。该设置兼顾了分离腔134的容积，及换热器200的出口212至分离部110的顶壁118之间的区域的容积，可保证压缩机的吸气量。
由于换热器200内用于容置分离装置100的空间是一定的，若第一距离小于第二距离，则会挤压分离部110的顶壁118与换热器200的出口212之间的空间。也即，若增大第二距离，则会导致第一距离减小，那么，会减小压缩机的吸气量，影响制冷设备的工作效率。

详细地，分离部110的入口114处形成有翻边132，翻边132与换热器的壳体210连接，也就是说，封板140与换热器的壳体210连接的同时，分离部110与换热器的壳体210连接。该设置增大了分离装置100与换热器200壳体的接触面积和接触角度，有利于提升分离装置100与换热器200壳体的装配结构强度，可以有效避免分离装置100移位甚至是掉落的情况发生。
具体地，翻边132与分离部110的侧壁122连接。
更具体地，翻边132与分离部110的侧壁122一体形成，该结构设置由于省去了翻边132与分离部110的侧壁122的装配工序，故而简化了翻 边132与分离部110的侧壁122的成型工序，有利于提升产品的加工效率。另外，翻边132与分离部110的侧壁122一体形成可保证产品的尺寸的精度。其中，翻边132与分离部110的侧壁122一体冲压成型。

Figure PCTCN2022097773-appb-000002
该设置既可保证扰流板150的扰流效果，又不会对压缩机的吸气量造成影响。
具体的，d1等于d2的四分之一、d1等于d2的五分之一、d1等于d2的六分之一等等，在此不一一列举。
进一步地，如图1所示，扰流板150设置有至少一个连接孔152，连接孔152用于与翻边132焊接连接。
其中，通过合理设置扰流板150的结构，使得扰流板150设置有一个 连接孔152，或者扰流板150设置有多个连接孔152。当扰流板150设置有多个连接孔152时，多个连接孔152间隔布置。
采用点焊的方式将扰流板150的连接孔152与翻边132焊接在一起。具体地，连接孔152与翻边132对应设置，连接孔152的孔壁与翻边132合围出凹槽结构，焊料填充于凹槽结构内，以将扰流板150和翻边132稳固且牢靠地装配在一起。

具体地，加强筋160的第一端连接第一子侧壁124，加强筋160的第二端连接第二子侧壁126。也即，加强筋160地设置能够保证第一子侧壁124和第二子侧壁126之间的间距，进而可保证入口114的过流截面面积。
进一步地，加强筋160的数量为多个，多个加强筋160间隔布置。
其中，加强筋160的数量为多个，多个加强筋160间隔布置，该设置增多了加强筋160与分离部110的接触面积和接触角度，有利于提升加强筋160与分离部110的装配结构强度，有利于提升分离装置100的整体结构强度。
具体地，加强筋160与分离部110通过焊接的方式连接在一起。

制冷设备工作时，气态冷媒被压缩机吸入，冷媒先与封板140发生第一次撞击分离后，冷媒的流向发生第一次改变。由于压差原因，冷媒会朝着分离部110的分离器内流动，与分离部110的顶壁118撞击发生第二次分离。第二次撞击分离完成后紧接着与分离部110的第一子侧壁124和第二子侧壁126发生第三次撞击分离，最终分离后得到的气态制冷剂中几乎不含液态。
