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,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。

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:
