并且，本实施例提供的排放装置的结构较简单，成本较低且重量较轻，具有较广泛的适用范围。
在一实施例中，如图11和图12所示，分水组件3还包括螺旋导流片33。螺旋导流片33设置于排气管32的外壁，且螺旋导流片33形成分水流道。需要说明的是，分水流道可以由螺旋导流片33、导流板31及第一排管21的内壁形成。示例地，螺旋导叶片33呈螺旋状，并沿排气管32的轴向绕设在排气管32上。
在一实施例中，为了使混合流体能够沿分水流道流动，螺旋导流片33的外边缘能够抵在第一排管21的内壁上，以防止混合流体经螺旋导流片33与第一排管21内壁之间的间隙直接流入排气管32的第二端。
本实施例中，分水组件3可以为一体结构，也即是，导流板31、排气管32及螺旋导流片33能够在一次制造工艺中一次成型，保证了导流板31与排气管32之 间、及螺旋导流片33及排气管32之间连接的牢固性。
本实施例中，如图7所示，导流板31与第一排管21的轴线呈预设夹角设置，也即是，导流板31在第一排管21内呈倾斜状，并且，导流板31的第一端与第一排管21内壁的抵接位置位于排气孔下方，也即是，导流板31靠近第二排管22的一端高于导流板31靠近排气孔的一端，通过该设置，一方面能够使由第二排管22排出的混合流体撞击在导流板31上，实现撞壁分离，进一步提高了气液分离的效果，另一方面，还便于由排气管32一端流出的气体顺利进入排气孔中。示例地，当第一排管21的截面形状为圆形时，导流板31可以呈椭圆状。
在一实施例中，如图5所示，排放管组件2还包括安装于支撑壳体1上的第三排管23。其中，第三排管23连接于第一排管21的一端，在一实施例中，第三排管23连接在第一排管21的侧壁且与第二排管22相对设置，第三排管23连通于排气孔，设置为传输分离后的气体至预设位置。
在一实施例中，如图2所示，第三排管23远离第一排管21的一端还可以有弯管25，弯管25可以根据需要延伸至车辆的后部。
如图3所示，第二排管22和第三排管23中的至少一个上设有消音孔24，第二排管22上的消音孔24设置为对混合流体进行消音，使得混合流体的能量能够降低，进而减少噪音。第三排管23上的消音孔24设置为对气液分离后的气体进行消音，使得气体的能量能够降低，进一步减少噪音。本实施例提供的排放装置不仅能够实现气水分离及液体的存储，还具有对混合流体降噪的功能，使得排放装置的功能更丰富。
在一实施例中，如图3和图4所示，排放装置还包括安装于支撑壳体1上方的消音壳体5，在其他实施例中，消音壳体5可以通过胶粘的方式固定在支撑壳体1上。消音壳体5内具有消音腔，消音腔中固定有吸声结构，消音孔24能够连通于消音腔，使得混合流体或气体能够进入消音腔中，吸声结构能够对消音腔内的混合流体或气体的能够进行吸收，进而降低混合流体或气体的能量，从而降低混合流体及气体流动的噪声。采用本实施例提供的排放装置对混合流体处理后，排放噪声能够比现有技术中降低方式处理后的噪音降低15分贝左右。降噪效果明显。本实施例中的吸声结构可以为玻璃纤维、石棉等结构。
在一实施例中，如图4所示，消音壳体5朝向支撑壳体1的表面具有槽结构51，槽结构51与支撑壳体1相互配合以容置第一排管21、第二排管22及第三排管23，也即是，本实施例中的第二排管22和第三排管23支撑于支撑壳体1及消音壳体5 之间。通过将消音壳体5设置在第二排管22的上方，能够降低混合流体中的液体进入消音壳体5的几率，进而能够降低消音壳体5内的吸声结构被液体浸湿的几率，保证了吸声结构的吸声效果。
在一实施例中，如图5所示，支撑壳体1为空腔结构，且支撑壳体1内固设有位于第一排管21两侧的两个支撑板12。第二排管22设置于支撑壳体1的侧壁和一个支撑板12上，第三排管23设置于支撑壳体1的侧壁和另一个支撑板12上。通过将支撑壳体1设置为空腔结构，使得部分混合流体能够通过消音孔24进入支撑壳体1内，并在支撑壳体1中多次折射，也能够实现混合流体的消音处理。在一实施例中，为了避免混合流体与气液分离后的气体相互混合，两个支撑板12与支撑壳体1的内壁密封连接，且消音壳体5与支撑壳体1之间的连接也为密封连接，以降低分离后的气体中夹带较多液体的几率。
在一实施例中，支撑壳体1的侧壁及支撑板12上可以设有弧形槽，弧形槽的形状能与第二排管22及第三排管23的形状相匹配，第二排管22和第三排管23能够卡在弧形槽中，进而能够提高第二排管22及第三排管23的稳定性。
请参考图5，消音孔24可以包括圆形孔241和方形孔242。其中，圆形孔241设置于第二排管22和第三排管23中的至少一个的朝向支撑壳体1的侧上壁，方形孔242设置于第二排管22和第三排管23中的至少一个的朝向消音壳体5的侧壁，于图5中所示的排放装置而言，方形孔242位于第二排管22或第三排管23的上方，圆形孔241位于第二排管22或第三排管23的下方，且方形孔242的面积大于圆形孔241的面积。通过该设置，对于第二排管22而言，较多的混合流体能够通过方形孔242进入消音壳体5内，使得该部分混合流体内的能量能够被消音壳体5内的吸音结构充分吸收，从而实现消音，还有较少的混合流体能够通过圆形孔241进入支撑壳体1内，进而使得该部分混合流体内的能够在支撑壳体1内消耗，从而实现消音。本实施例中，支撑壳体1也可以设有吸声结构。
在一实施例中，请继续参考图5，第一排管21的第二端具有收缩端口211，收缩端口211的尺寸小于第一排管21中部的尺寸，便于附着在第一排管21内壁上的液体流入储水箱4中。
为了提高支撑壳体1与储水箱4之间连接的强度，如图5所示，排放装置还包括加强筋6。支撑壳体1的外形轮廓呈棱锥状，加强筋6连接于呈棱锥状的支撑壳体1侧壁和储水箱4顶壁之间。在一实施例中，加强筋6的截面可以呈三角形。
在一实施例中，如图1所示，储水箱4上还设有溢流口43，溢流口43靠近储 水箱4的顶部设置，溢流口43的设置能够在储水箱4充满液体且电磁阀41没有开启的动作时，储水箱4内的液体能够通过溢流口43流出，以防止液体进入第一排管21中，保证了排放装置的可靠性。
如图7所示，排水口设置在储水箱4的底壁，且储水箱4的底壁呈倾斜状，在一实施例中，储水箱4底壁设有排水口的第一端低于储水箱4底壁的第二端，以便于储水箱4内的液体顺利流出。
