Description
本申请要求2022年1月29日提交的、发明名称为“换热器和空调器”的中国专利申请CN202220244881.1的优先权，上述中国专利申请的全部内容通过引用并入本申请中。
本发明涉及换热技术领域，具体提供一种换热器和空调器。
随着空调器日益普及，用户对空调器的综合性能也提出了越来越高的要求；特别是对于空调器的换热性能，其直接影响到空调器的综合能耗，而换热器的换热效率又会直接影响整个空调器的换热性能，因而其显得尤为重要。然而，由于空调器在制冷模式和制热模式之间转换的过程中，室内换热器和室外换热器的功能会发生互换；例如，制冷时冷凝器起冷凝换热作用，而制热时冷凝器又是起蒸发换热作用。基于此，如果空调器在制冷过程和制热过程中采用统一的冷媒分流方式，则不能保证换热器在制冷模式和制热模式中都能够实现均匀分流的效果，也就不能保证空调器在运行制冷模式和运行制热模式时都能够达到最优的换热效果。
具体地，现有空调器在运行制冷模式和运行制热模式时均采用统一的分流方式，基于这种统一的分流方式，空调器为了提高制冷量和制冷能效比，则需要相应增加过冷，即，相应增加过冷管的设置，但是，过冷管设置过多，则又会对空调器的制热能力和制热能效比产生不良影响；然而，空调器为了提高制热量和制热能效比，则又需要相应减少过冷管的设置，甚至是取消过冷设计。因此，在设计换热器时，为了提升制冷能力和能效，就必然要牺牲部分制热性能，而为了提升制热性能，又必然需要减少过冷设计，相应也就会牺牲部分制冷性能，这是一个矛盾的 问题。因而对于现有换热器，通常同一个换热器无法同时实现制冷运行和制热运行均达到最优换热。
相应地，本领域需要一种新的换热器和空调器来解决上述问题。

以本发明的换热器用作室外换热器时为例，参阅图1，如图1所示，所述换热器包括换热管组11、集气管组12和集液管组13，参阅图1中的方位，换热管组11位于所述换热器的中部，集气管组12位于所述换热器的左部，集液管组13位于所述换热器的右部；当然，这种具体设置方位并不是限制性的，本领域技术人员可以根据实际使用需求自行调整。换热管组11包括多个换热管111，多个换热管111呈并联设置，集气管组12包括多个集气管，所述多个集气管呈串联设置，相邻两个所述集气管之间设置有第一单向阀，并且每个所述集气管和至少一个换热管111相连通，集液管组13包括多个集液管，所述多个集液管和多个换热管111相连通。需要说明的是，本发明不对换热管111、所述集气管和所述集液管的具体设置数量和尺寸作任何限制，本领域技术人员可以根据实际使用需求自行设定。
在本具体实施例中，换热管111的数量为十个，所述集气管的数量为两个，两个所述集气管分别为第一集气管121和第二集气管122，第一集气管121位于第二集气管122的上方，第一集气管121和第二集气管122之间设置有第一单向阀123，第一单向阀123设置成在制热工况下导通以连通第一集气管121和第二集气管122，并且第一单向阀123还设置成在制冷工况下不导通以隔断第二集气管122。需要说明的是，本发明不对第一单向阀123的具体类型作任何限制，本领域技术人员可以根据实际使用需求自行设定。
进一步地，位于上方的第一集气管121和六个换热管111相连通，而位于下方的第二集气管122和四个换热管111相连通，即，第一集气管121连通的换热管111的数量大于第二集气管122连通的换热管111的数量，并且第一集气管121的长度大于第二集气管122的长度。需要说明的是，本发明不对第一集气管121和第二集气管122连通的换热管111的具体数量和长度作任何限制，只要作为一种优选的设置方式，第一集 气管121连通的换热管111的数量大于第二集气管122连通的换热管111的数量且第一集气管121的长度大于第二集气管122的长度即可，技术人员可以根据实际使用需求自行设定。
基于这种设置方式，在所述空调器运行制热工况时，第一单向阀123导通，以使第一集气管121和第二集气管122连通，进而使得第一集气管121和第二集气管122均能够参与到制热循环中，从而有效保持较小的出口温差，保证制热分流的均匀性，提升蒸发压力，以便提升所述换热器的制热能力和制热效率；在所述空调器运行制冷工况时，第一单向阀123不导通，以使第二集气管122被隔断，进而使得仅有第一集气管121参与到制冷循环中，从而有效提升过冷度，以便提升所述换热器的制冷能力和制冷效率。
继续参阅图1，如图1所示，在本具体实施例中，所述多个集液管包括第一集液管131和第二集液管132，第一集液管131和第二集液管132呈并联设置。当然，这仅是一种优选的设置方式，但并不是限制性的设置方式，技术人员可以根据实际使用需求自行设定。
进一步地，第一集液管131和一个换热管111相连通，并且第一集液管131上设置有单向节流阀1311，单向节流阀1311设置成在制热工况下导通且节流，在制冷工况下导通而不节流。换言之，在所述空调器运行制热工况时，单向节流阀1311能够对流经其的冷媒起到节流作用，而在所述空调器运行制冷工况时，单向节流阀1311不对流经其的冷媒起节流作用，以便同时兼顾所述换热器的制冷能力和制热能力。还需要说明的是，本发明不对单向节流阀1311的具体类型和具体设置位置作任何限制，本领域技术人员可以根据实际使用需求自行设定。
另外，第二集液管132的主路上设置有第二单向阀1321，第二单向阀1321设置成在制热工况下导通且在制冷工况下不导通；即在所述空调器运行制热工况时，第二单向阀1321导通以允许冷媒流通，而在所述空调器运行制冷工况时，第二单向阀1321不导通以截断冷媒。需要说明的是，本发明不对第二单向阀1321的具体类型和具体设置位置作任何限制，本领域技术人员可以根据实际使用需求自行设定。
进一步地，参阅图1中的方位，位于第二单向阀1321上方的第二集 液管132设置成两个呈并联设置的集液支路，即，第一集液支路1322和第二集液支路1323。需要说明的是，本发明不对所述集液支路的具体设置数量和具体设置位置作任何限制，技术人员可以根据实际使用需求自行设定，只要所述集液支路位于第二单向阀1321的下游即可，可以理解的是，此处所述的下游指的是第二单向阀1321导通时的下游。
继续参阅图1，如图1所示，在本具体实施例中，第一集液支路1322上设置有第一分液器1324，第二集液支路1323上设置有第二分液器1325；需要说明的是，本发明不对第一分液器1324和第二分液器1325的具体结构和类型作任何限制，技术人员可以根据换热管111的具体设置数量自行设定。具体地，第一分液器1324能够将第一集液支路1322继续分为三路，这三路分别与一个换热管111相连通；第二分液器1325能够将第二集液支路1323继续分为六路，这六路分别与一个换热管111相连通。当然，这种设置方式并不是限制性的，技术人员可以根据实际使用需求自行调整。
此外，所述换热器还包括两个风机(图中未示出)，两个所述风机分别设置于所述换热器的上部和下部，以便有效提升换热效率。需要说明的是，本发明不对所述风机的具体设置数量、设置位置和类型作任何限制，技术人员可以根据实际使用需求自行设定。
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仅仅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。
