如图1-5所示，根据本申请实施例的换热器包括集流管1、多个换热管2和隔板6，集流管1具有管壁和内腔，集流管1的横截面为圆环形，即集流管1为圆管。
隔板6设在集流管1的内腔，隔板6沿集流管1的长度方向(图1所示的左右方向)延伸，以将集流管1的内腔分隔成第一腔体101和第二腔体102。换言之，集流管1的内腔包括均沿集流管1的长度方向延伸的第一腔体101和第二腔体102。
换热管2具有多个，多个换热管2沿集流管1的长度方向(图1所示的左右方向)相互间隔开。可选地，多个换热管2沿集流管1的长度方向均匀间隔布置，即相邻换热管2之间的距离相等。
每个换热管2具有第一端21和内腔，换热管2的第一端21依次穿过集流管1的管壁、第一腔体101和隔板6插入第二腔体102，且换热管2的内腔与第二腔体102连通。在本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
根据本申请实施例的换热器，通过在集流管1的内腔设置隔板6以将集流管1分隔成 第一腔体101和第二腔体102，换热管2的第一端21依次经过集流管1的管壁、第一腔体101和隔板6插入第二腔体102，从流体进口进入第二腔体102的冷媒可均匀地向多个换热管2分配，提高了换热效率。
换热管2可以为扁管，业内也称微通道扁管，扁管的使用有利于降低空调的重量、减小空调的尺寸。其中，扁管通常内部设有多个供冷媒流动的通道。相邻的通道彼此隔离。多个通道排成一列，共同影响扁管的宽度。扁管整体呈扁平状，其长度大于宽度，宽度又大于其厚度。扁管的长度方向即由扁管内的所述通道所确定的冷媒流动方向。扁管的长度方向可以是直线型或折线型或弯曲型等。这里所说的扁管并不局限于此种类型，也可以是其它形态。比如，相邻的通道可不完全隔离。又比如，所有的通道可以排成两列，只要其宽度仍大于厚度即可。
可选地，集流管1水平放置且长度大于250mm，换热管2竖直放置，集流管1的直径大于换热管2的宽度，以便换热管2的第一端21的宽度可完全位于集流管1的内腔。这里，需要理解的是，如图4所示，左右方向定义为换热管2的宽度方向。
在一些实施例中，如图1-3所示，换热管2的第一端21与隔板6之间的距离为0-5mm。可选地，换热管2的第一端21与隔板6之间的距离为0-2mm。这里，需要理解的是，换热管2的第一端21与隔板6之间的距离为换热管2的第一端21的端面211(图1所示的换热管2的上端面)和隔板6的邻近第二腔体102的表面(图1所示的隔板6的上表面)之间的垂直距离，即换热管2的第一端伸入第二腔体102的深度为0-2mm。
在一些实施例中，换热器还包括翅片5，翅片5设在相邻换热管2之间，由此通过翅片5和换热管2进行换热，提高换热效率。具体地，多个换热管2彼此间隔开，翅片5设在相邻换热管2之间的间隙中，且翅片5至少部分与换热管2连接。
在一些实施例中，集流管1的管壁具有多个贯穿集流管1的管壁的插孔，多个插孔沿集流管1的长度方向(图1所示的左右方向)布置，且相邻插孔相互间隔开，隔板6具有多个沿隔板6的厚度方向贯穿隔板6的槽孔61，多个槽孔61沿隔板6的长度方向相互间隔布置，且多个槽孔61与多个插孔一一对应，即一个槽孔61对准一个插孔，槽孔61连通第一腔体101和第二腔体102，换热管2的第一端依次穿过插孔、第一腔体101和槽孔61插入第二腔体102。
可选地，如图3所示，在槽孔61上采用冲压的方式沿从第二腔体102朝向第一腔体101的方向(图1、3所示的从上向下的方向)进行翻边。
在一些实施例中，换热器还包括分配管3，分配管3具有第一端(图1所示的分配管3的左端)和第二端(图1所示的分配管3的右端)，集流管1具有第一端(图1所示的集流管1的左端)和第二端(图1所示的集流管1的右端)，分配管3的第一端为流体进口， 以便于冷媒流入分配管3内，分配管3的第二端封闭且从集流管1的第一端伸入第二腔体102。可以理解的是，为了顺利分配冷媒，分配管3位于换热管2上方。可选地，分配管3与换热管2的第一端21间隔开一定距离。在另一些实施例中，分配管3与换热管2的第一端至少部分相接触。
分配管3具有管壁和内腔，分配管3的管壁具有通孔31，通孔31连通第二腔体102和分配管3的内腔。换言之，如图1所示，分配管3的左端在集流管1左侧，分配管3的右端从集流管1的左端伸入第二腔体102，且分配管3的右端封闭，通孔31贯穿分配管3的管壁的壁厚，通孔31连通分配管3的内腔和第二腔体102，分配管3在上下方向上高于换热管2的第一端21。可以理解的是，通过分配管3的第一端流入分配管3的冷媒流向分配管3的第二端，且分配管3内的冷媒经通孔31流入第二腔体102。在本申请中，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。
可选地，分配管3在第二腔体102中的长度与集流管1的长度大体一致。具体地，分配管3的第二端从集流管1的第一端伸入第二腔体102且延伸至集流管1的第二端，如图1所示，分配管3的右端从集流管1的左端伸入第二腔体102内且向右延伸并延伸至集流管1的右端。
在一些实施例中，如图4所示，通孔31可开设在分配管3的沿分配管3的周向的任意位置，即沿分配管3的周向旋转一圈的任意位置均可开设通孔31。换言之，如图4所示，在具有通孔31的分配管3的横截面上，定义分配管3的水平直径所在的直线为水平线，通孔31可位于水平线上方，且通孔31的中心与分配管3的中心的连线与水平线的夹角α为0°<α<180°，通孔31也可位于水平线下方，且通孔31的中心与分配管3的中心的连线与水平线的夹角α为0°<α<180°。
在一些实施例中，通孔31设有多个，多个通孔31沿分配管3的长度方向(图1所示的左右方向)间隔布置。可以理解的是，通过将分配管3的管壁上设置多个沿分配管3的长度方向彼此间隔开的通孔31，可以使分配管3内的冷媒均匀地流入第二腔体102。
在一些可选的实施例中，多个通孔31沿从分配管3的第一端朝向分配管3的第二端的方向(图1所示的从左向右的方向)依次为第一通孔、第二通孔、第三通孔、……第n-1通孔和第n通孔，其中第i+1通孔和第i通孔之间的距离为：
d i＝α iL 0，i＝1，2，……n-1，α＝0.618，L 0为相邻换热管2之间的距离。
例如，第二通孔和第一通孔之间的距离为：d 1＝α 1L 0，第三通孔和第二通孔之间的距离为：d 2＝α 2L 0。这里，需要理解的是，第一通孔是分配管3上最邻近流体进口的一个通 孔31，如图1所示，第一通孔为最左侧的通孔31。
在一些具体的实施例中，多个换热管2沿从分配管3的第一端朝向分配管3的第二端的方向(图1所示的从左向右的方向)依次为第一换热管、第二换热管、第三换热管、第四换热管……，第一通孔位于第三换热管和第四换热管之间。这里，第一换热管是最邻近流体进口的一个换热管2，如图1所示，第一换热管为最左侧的换热管2，换言之，最邻近流体进口的一个通孔31开设在第三换热管和第四换热管之间。

d i＝2.5α iL 0，i＝1，2，……n-1，α＝0.618，L 0为相邻换热管2之间的距离。
可选地，通孔31为圆孔，若d i＜D 0，则d i＝D 0+2，D 0为通孔31的直径。具体地，1mm<D 0<3mm。
这里，可以理解的是，集流管1沿长度方向的中间位置即为集流管1的1/2长度处，如图1所示的B-B位置处。
在一些实施例中，如图1、5所示，换热器还包括支撑组件4，支撑组件4包括第一支撑件41和第二支撑件42，第一支撑件41具有第一端(图5所示的第一支撑件41的下端)和第二端(图5所示的第一支撑件41的上端)，分配管3具有外周面，第一支撑件41的第一端与集流管1连接，第一支撑件41的第二端位于分配管3下方且与分配管3的外周面相接触。由此，通过第一支撑件41支撑分配管3。可以理解的是，第一支撑件41的设置形式并不限于此，例如，在一些可选的实施例中，第一支撑件41的第二端还可以位于分配管3下方且与分配管3相连。在另一些可选的实施例中，第一支撑件41可以位于分配管3的上方，且第一支撑件41的上端与集流管1连接，第一支撑件41的下端与分配管1相连。
具体地，第一支撑件41具有多个，多个第一支撑件41沿集流管1的长度方向(图1所示的左右方向)相互间隔布置，由此，通过多个第一支撑件41共同支撑分配管3。可以理解的是，本申请并不限于此，第一支撑件41还可以仅有一个，一个第一支撑件41位于集流管1沿长度方向的中间位置。
在一些具体的实施例中，第一支撑件41的第一端(图5所示的第一支撑件41的下端)与集流管1的外周面相连，第一支撑件41的第二端(图5所示的第一支撑件41的上端)从集流管1的外周面依次穿过集流管1的管壁、第一腔体101和隔板6伸入第二腔体102，且第一支撑件41的第二端与分配管3的外周面相接触。具体地，如图5所示，第一支撑件41包括从上向下依次设置且彼此连接的第一段和第二段，其中第一段在集流管1的内腔且从下向上穿过隔板6与分配管3的外周面相接触，第二段贴设在集流管1的外周面上。
在一些实施例中，支撑组件4还包括第二支撑件42，第二支撑件42从集流管1的第二端(图1所示的集流管1的右端)伸入第二腔体102，第二支撑件42位于分配管3下方且与分配管3的外周面相接触。可以理解的是，第二支撑件42的设置形式并不限于此，例如，在一些可选的实施例中，第二支撑件42位于分配管下方且与分配管3的外周面相连。在另一些可选的实施例中，第二支撑件42位于分配管3上方且与分配管3的外周面相连。可以理解的是，本申请并不限于此，例如在分配管3的第二端焊接在集流管1的内腔的第二端时，支撑组件4可以不设置第二支撑件42。在本申请图示的实施例中，通过同时设置第一支撑件41与第二支撑件42，能够更好地对分配管3进行支撑和定位，使分配管3更加固定，不易在制造与装配的过程中移位。
