Abstract
一种冷媒整流管及空调室内机，包括使冷媒进入多个分支通道分成多支流路，多支流路中的冷媒流出冷媒整流管的出口端再进入一单通道中经过碰撞冲击进行混合，使得气液两相混合的冷媒转变为气液均相的冷媒再进入冷媒分配器，这样冷媒分配器在对冷媒进行分配时就不会受气态冷媒的影响而导致室内换热器的不同流路中冷媒分配不均的问题。
Description
本发明属于空调技术领域，具体涉及一种冷媒整流管及空调室内机。
现有的房间空调器、单元式空调器及多联式空调器都包括空调室外机和空调室内机两部分，空调室内机在其有限的内部空间中需要同时安装电子膨胀阀、1到2个干燥过滤器、冷媒分配器及分液毛细管，并通过若干根U型或者L型弯管对这些器件之间进行紧凑的连接。冷媒经过电子膨胀阀节流后会从单相变成气液两相，气液两相的冷媒在通过U型或者L型弯管时受离心力的作用会发生气液分层，液态冷媒通常都集中在弯管的外侧，而气态冷媒则集中在弯管的内侧。发生气液分层的冷媒一旦由冷媒分配器直接分配到室内换热器中，会导致室内换热器的不同流路中液态冷媒的分布极不均匀，从而降低了室内换热器的换热效率。
现有的空调室内机中对冷媒进行整流的方案为让气液分层后的冷媒经过一段直管，其目的是通过让冷媒在一段直管中快速流动以达到重新混合并形成均相流型或者对称流型再进入冷媒分配器。但是，一般需要直管的长度大于100mm才能实现对冷媒的有效整流，实际中发现由于空调室内机内部空间受限导致直管的长度往往达不到最佳长度要求，影响整流效果。实验测试研究的结果表明，现有的该类空调室内机中不同流路的换热量仍存在20％左右的偏差。
相应地，本领域需要新的一种结构紧凑的冷媒整流管及空调室内机来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有的空调室内机通过直管进行冷媒整流因空间受限导致室内换热器的不同流路之间 发生偏流以及性能不稳定的问题，本发明提供一种紧凑的冷媒整流管及空调室内机。
首先，在本发明提供的一种冷媒整流管中，所述冷媒整流管的进口端和出口端分别形成有一单通道，所述冷媒整流管内形成有将两个所述单通道连通的多个分支通道，将发生气液分层之前的冷媒均匀的分成多股，并在出口端重新汇合在一起以达到气液两相冷媒均匀混合的目的；所述冷媒整流管的出口端用于与冷媒分配器的进口端连接。
作为本发明提供的上述冷媒整流管的一种优选的技术方案，所述冷媒整流管的进口端用于与弯管连接；所述分支通道有两个，一个所述分支通道位于所述弯管的中心轴线所在平面的一侧，另一个所述分支通道位于所述弯管的中心轴线所在平面的另一侧。
作为本发明提供的上述冷媒整流管的一种优选的技术方案，所述冷媒整流管包括两个三通管；所述三通管的一端设置有单通道，另一端设置有与其单通道连通的双通道；所述两个三通管的设置双通道的一端一一对应且彼此对接以形成两个所述分支通道；所述冷媒整流管的进口端为一个所述三通管的设置有单通道的一端，所述冷媒整流管的出口端为另一个所述三通管的设置有单通道的一端。
作为本发明提供的上述冷媒整流管的一种优选的技术方案，所述冷媒整流管还包括两端或整体都设置有内螺纹的连接套；所述两个三通管的设置双通道的一端均设置有外螺纹，所述连接套的两端分别与所述两个三通管的所述外螺纹连接。
作为本发明提供的上述冷媒整流管的一种优选的技术方案，所述冷媒整流管在所述多个分支通道所在的管段形成有L形或U形的弯管。
作为本发明提供的上述冷媒整流管的一种优选的技术方案，所述冷媒整流管包括两个三通管；所述三通管的一端设置有单通道，另一端设置有与其单通道连通的双通道；所述两个三通管的双通道都通过所述弯管中的两个分支通道一一对应地连通；所述冷媒整流管的进口端为一个所述三通管的设置有单通道的一端，所述冷媒整流管的出口端为另一个所述三通管的设置有单通道的一端。
作为本发明提供的上述冷媒整流管的一种优选的技术方案，所述多个分支通道为多个冷媒管；或者所述多个分支通道为所述冷媒整 流管自身形成的多个孔道。
作为本发明提供的上述冷媒整流管的一种优选的技术方案，所述冷媒整流管的出口端设置成供所述冷媒分配器的进口端插接的连接口。
作为本发明提供的上述冷媒整流管的一种优选的技术方案，所述多个分支通道的有效流通总面积与所述冷媒整流管的进口端的单通道的流通面积和出口端的单通道的流通面积均相等。
然后，本发明还提供了一种空调室内机，所述空调室内机包括上述任一种技术方案中所述的冷媒整流管。
在本发明提供的一种冷媒整流管及空调室内机中，冷媒整流管内形成有将其进口端和出口端的单通道连通的多个分支通道，冷媒整流管的出口端用于与冷媒分配器的进口端连接。如此，冷媒分开后先进入多个分支通道分成多支流路，然后多支流路中的冷媒流出冷媒整流管的出口端时再进入一单通道中经过碰撞冲击重新进行混合，使得冷媒在单通道中转变成气液均相态后再进入冷媒分配器，这样冷媒分配器在对冷媒进行分配时就不会受冷媒气液分层的影响而导致室内换热器的不同流路中冷媒分配不均的问题，从而可以保证室内换热器的换热效率。
由于冷媒在经过弯管受离心作用发生气液分离时，弯管的弯道内侧为气态冷媒且在其弯道外侧为液态冷媒，在本发明提供的一种冷媒整流管及空调室内机中，冷媒整流管的进口端用于与弯管连接，冷媒整流管的两个分支通道中，一个分支通道位于弯管的中心轴线所在平面的一侧，另一个分支通道位于弯管的中心轴线所在平面的另一侧。如此，气液两相冷媒被均匀的分开进入多个分支通道分成多支流路，使得冷媒进入两个分支通道后的干度基本相等。对于单股冷媒即便经过U型弯发生了分层，但两股冷媒碰撞冲击后重新混合变成均相冷媒，并进一步地保证了室内换热器的换热效率。

此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可 以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
为了解决现有技术中的上述问题，即为了解决现有的空调室内机中存在的冷媒经过弯管发生气液分离后直接进入冷媒分配器，使得冷媒分配器不能将冷媒均匀地分配到室内换热器的不同流路，导致室内换热器的换热效率降低的问题，本发明提供了一种冷媒整流管及空调室内机。
首先，如图1至图5所示，在本实施例提供的一种冷媒整流管中，冷媒整流管的进口端11和冷媒整流管的出口端12分别形成有一单通道101，冷媒整流管内形成有将两个单通道101连通的多个分支通道102；冷媒整流管的出口端12用于与冷媒分配器(图中未示出)的进口端连接。
示例性地，本实施例是以冷媒整流管中设置有两个分支通道102为例进行说明的，但是本领域技术人员可以根据实际需要在冷媒整流管中设置三个及三个以上的分支通道102，或者直接采用多孔的微通道扁管。
此外，本实施例提供的冷媒整流管可以一体成型也可以由多个管段连接而成。例如，可以将设置有单通道101的管段、设置多个分支通道102的管段进行连接，其连接方式可为插接、螺纹连接或者通过连接套进行连接等。
由于铜管具有优良的弯曲性能、疲劳强度和抗氧化性，且具有寿命长的优点，所以本实施例中的冷媒整流管优先选用为铜管材质，但本领域技术人员在具体实施时冷媒整流管也可以选用铝管和塑料软管等。
在本实施例提供的一种冷媒整流管中，冷媒整流管内形成有冷媒整流管的进口端11和冷媒整流管的出口端12的单通道101连通的多个分支通道102，冷媒整流管的出口端12用于与冷媒分配器的进口端连接。如此，冷媒进入多个分支通道102分成多支流路，然后多支流路中的冷媒流出冷媒整流管的出口端12时再进入一单通道101中经过碰撞冲击重新进行混合，使得气液两相分层的冷媒转变为气液均相的冷媒然后再进入冷媒分配器，这样冷媒分配器在对冷媒进行分配时就不会受气态冷媒的 影响而导致室内换热器的不同流路中冷媒分配不均的问题，从而可以保证室内换热器的换热效率。
作为本实施例提供的上述冷媒整流管的一种优选的实施方式，如图1和图2所示，由于冷媒在经过弯管4受离心作用发生气液分离时，弯管4的弯道内侧为气态冷媒且在其弯道外侧为液态冷媒，在本实施例提供的一种冷媒整流管中，冷媒整流管的进口端11用于与弯管4连接；该冷媒整流管的分支通道102有两个，一个分支通道102位于弯管4的中心轴线所在平面的一侧，另一个分支通道102位于弯管4的中心轴线所在平面的另一侧。如此，使得冷媒进入两个分支通道102后的干湿度基本相等，从而更有利于两股冷媒碰撞冲击后重新混合变成气液均相的冷媒，并进一步地保证了室内换热器的换热效率。
作为本实施例提供的上述冷媒整流管的一种优选的实施方式，继续参照图1和图2，冷媒整流管包括两个三通管(如图1和图2中的第一三通管2和第二三通管3)；三通管的一端设置有单通道101，另一端设置有与其单通道101连通的双通道；两个三通管的设置双通道的一端一一对应且彼此对接以形成两个分支通道102；冷媒整流管的进口端11为一个三通管的设置有单通道101的一端，冷媒整流管的出口端12为另一个三通管的设置有单通道101的一端。
作为本实施例提供的上述冷媒整流管的一种优选的实施方式，继续参照图1和图2，两个三通管的设置双通道的一端可以通过焊接实现连接；此外，作为另一种可实施的方式，冷媒整流管还包括两端或整体都设置有内螺纹的连接套(图中未示出)；两个三通管的设置双通道的一端均设置有外螺纹，连接套的两端分别与两个三通管的外螺纹连接。如此，两个三通管的双通道对接后，在两个三通管的连接位置通过连接套螺纹连接，以使得两个三通管连接的更可靠。
再如，如图2所示，三通管设置有双通道的一端可以为设置有两个孔道的一个管段，这样可以通过一个连接管的一端插入一个三通管双通道中的一个通道，该连接管的另一端插入另一个三通管中双通道中的一个通道，然后通过另外一个连接管连接两个三通管中双通道的另一个通道。其中，可以将连接管的两端分别焊接在三通管上；此外，作为另一种可实施的方式，可以在双通道中设置内螺纹，连接管的两端设 置外螺纹，使得连接管与双通道实现螺纹连接。
此外，三通管设置有双通道的一端还可以为一管段中设置有两个分支管，在连接时可以使用连接管和连接套，在此不再赘述。
作为本实施例提供的上述冷媒整流管的一种优选的实施方式，参照图3、图4和图5，冷媒整流管在多个分支通道102所在的管段形成有L形或U形的弯管4。其中，仅有U形的弯管4被图3示出。如此，冷媒在流过冷媒整流管的弯管4部分时即使发生气液两相分离，其在进入另一单通道101时，多股冷媒冲击碰撞即可进行有效的混合。
作为本实施例提供的上述冷媒整流管的一种优选的实施方式，继续参照图3、图4和图5，冷媒整流管包括两个三通管(如图3、图4和图5中的第一三通管2和第二三通管3)；三通管的一端设置有单通道101，另一端设置有与其单通道101连通的双通道；两个三通管的双通道都通过弯管4中的两个分支通道102一一对应地连通；冷媒整流管的进口端11为一个三通管的设置有单通道101的一端，冷媒整流管的出口端12为另一个三通管的设置有单通道101的一端。
作为本实施例提供的上述冷媒整流管的一种优选的实施方式，多个分支通道102为多个冷媒管；或者多个分支通道102为冷媒整流管自身形成的多个孔道。
作为本实施例提供的上述冷媒整流管的一种优选的实施方式，冷媒整流管的出口端12设置成供冷媒分配器的进口端插接的连接口。如此，可以实现冷媒整流管的出口端12与冷媒分配器的进口端的插接。
作为本实施例提供的上述冷媒整流管的一种优选的实施方式，多个分支通道102的有效流通总面积与冷媒整流管的进口端11的单通道101的流通面积和冷媒整流管的出口端12的单通道101的流通面积均相等。如此，可以减少或避免由于冷媒整流管的流通截面大小变化导致冷媒压力改变，而带来的影响冷媒发生气液两相变化的因素。
然后，本实施例还提供了一种空调室内机，该空调室内机包括上述任一种实施方式中的冷媒整流管。
示例性地，空调室内机在使用本实施例的冷媒整流管时，对于图1和图2所示的冷媒整流管，其进口端连接弯管4，出口端连接冷媒分配器的进口端。对于图3至图5所示的冷媒整流管，对冷媒整流管的进口 端11可以直接接入由电子膨胀阀流出的冷媒，冷媒整流管的出口端12连接冷媒分配器的进口端。
可以理解的是，本领域技术人员也可以将本实施例提供的冷媒整流管用于空调室外机。
当然，上述可以替换的实施方式之间、以及可以替换的实施方式和优选的实施方式之间还可以交叉配合使用，从而组合出新的实施方式以适用于更加具体的应用场景。
此外，本领域的技术人员能够理解，尽管在此所述的一些实施例包括其它实施例中所包括的某些特征而不是其它特征，但是不同实施例的特征的组合意味着处于本发明的保护范围之内并且形成不同的实施例。例如，在本发明的权利要求书中，所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
