Description

蒸发器流路结构、蒸发器、空调器室内机及空调器
本申请要求于2017年2月23日提交中国专利局、申请号为2017100996552、发明名称为“蒸发器流路结构、蒸发器、空调器室内机及空调器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及生活电器领域，具体而言，涉及一种蒸发器流路结构、一种蒸发器、一种空调器室内机及一种空调器。
背景技术
在相关技术中，分体挂壁式房间空调器的换热器通常采用两折、三折或者多折的设计，如果系统配置最优与流路设计最优的情况下仍达不到设计的冷量目标或者需加大冷量时，一般会通过扩大室内机的结构尺寸和增加换热器的长度即增加换热器的面积和室内机的循环风量来达到较大冷量的性能目标，因此，如果要开发冷量大一倍或者是更高的冷量的产品，那么室内机的尺寸就需要调整，而这样就会增加了模具费用和相关的成本，同时尺寸的增大，也影响房间的美观及占用了室内更多的空间。
目前，现有增加空调冷量的方案是，通过提高换热器的换热效率来实现所需冷量，蒸发器流路采用一进两出或者三进三出方案，一进两出蒸发器冷媒压损比较大，造成换热效率比较低，尤其是制冷能力偏低，流路越长，流阻越大，随着管内流速的降低而导致导换热率降低，也容易产生制冷剂偏流，致使难以有效换热，三进三出流路蒸发器的压损比较小，换热效率比较高，但如果流路均匀性设计不合理，换热器各路之间的冷媒会出现分配不均匀的情况，分流不均造成分流温差大，影响整机性能。
除了以上方案以外，也有采用背管的方案来解决，例如采用蒸发器后背或者前背管的方案进行增加换热面积，以达到相应的冷量要求，但背管 后会加大背管一侧的风阻，会导致室内机的循环风量变小，从而影响降低了蒸发器的换热效率，同时，背管后如果分流不均还会出现凝露或者漏水等相关可靠性问题。

在该实施例中，根据蒸发器内部各处的不同的风速，通过四个U管10与三个半圆形连接管12交替连接形成第一流路20；四个U管10与三个半圆形连接管12交替连接形成第二流路30；五个U管10与四个半圆形连接管12交替连接形成第三流路40；四个U管10与三个半圆形连接管12交替连接形成第四流路50，使得四路流路内的冷媒均进行充分地蒸发，同时，也不会出现过度蒸发的现象。

在具体实施例中，如图1所示，由长U管10与翅片14组成的四折结构，四折结构构成框式结构，其中，靠近室内机风轮的内侧为背风侧，靠近室内机进风格栅为内侧即迎风侧，如图6所示，蒸发器的翅片14同行通孔142孔距为18.2mm，异行通孔142孔距为16.17mm，并且，如图1所示，蒸发器流路结构1采用四进四出的流程，四进四出的流路以顺流的换热方式设计，流程结合室内机风道的风速分为四路，每路的流路的管数布局形式为第一流路20采用四个U管10，第二流路30采用四个U管10，第三流路40采用五个U管10，第四流路50采用四个U管10，同时，第一流路20与第二流路30的布局为等程流路布局。

在第四流路50中，由于蒸发器内的风速不均匀，因此，如图5所示，以一端U管10的一端口为第三进流口402进入，交替经过四个U管10与三个半圆形连接管12，其中，在迎风侧自上而下通过半圆形连接管12，在背风侧由下而上通过半圆形连接管12，以另一端U管10的一端口为第四出流口504流出。
根据本发明的第二方面实施例，本发明提出了一种蒸发器，包括：压缩机，设置有进口与出口；四路分流连接器，与出口相连通；笛形管，与进流口相连通；及如上述任一实施例提供的蒸发器流路结构1；其中，第一进流口202、第二进流口302、第三进流口402及第四进流口502与四路分流连接器相连通，第一出流口204、第二出流口304、第三出流口404及第四出流口504与笛形管相连通。
本发明提供的蒸发器，包括如上述任一实施例提供的蒸发器流路结构1，并通过将四路分流连接器一端与压缩机出口相连接，另一端与四路流路的进流口分别相连接，将笛形管一端与压缩机进口相连接，另一端与四路流路的出流口分别相连接，进而实现了四路流路同时换热，并且，因包括如上述任一实施例提供的蒸发器流路结构1，因此，本发明提供的蒸发器具有上述任一实施例提供的蒸发器流路结构1的全部有益效果，在此不一一列举。
在具体实施例中，第一进流口202、第二进流口302、第三进流口402及第四进流口502通过四路分流连接器与压缩机相连接，并进行分流，第 一出流口204、第二出流口304、第三出流口404及第四出流口504，经由笛形管汇总流入压缩机进口，四进四出的流程布局，降低了换热器的冷媒压损，提高了换热器的换热效率。
根据本发明的第三方面实施例，本发明提出了一种空调器室内机，包括：壳体；风轮，设置在壳体内，位于壳体一侧；进风格栅，设置在壳体内，位于壳体另一侧；及如上述任一实施例提供的蒸发器流路结构1；或如上述任一实施例提供的蒸发器；其中，蒸发器流路结构1或蒸发器位于风轮与进风格栅之间。
本发明提供的空调器室内机，因包括如上述任一实施例提供的蒸发器流路结构1；或如上述任一实施例提供的蒸发器，因此，本发明提供的空调器室内机具有上述任一实施例提供的蒸发器流路结构1，或如上述任一实施例提供的蒸发器的全部有益效果，在此不一一列举。
根据本发明的第四方面实施例，本发明提出了一种空调器，包括：如上述任一实施例提供的蒸发器流路结构1；或如上述任一实施例提供的蒸发器；或如上述任一实施例提供的空调器室内机。
本发明提供的空调器，因包括如上述任一实施例提供的蒸发器流路结构1；或如上述任一实施例提供的蒸发器；或如上述任一实施例提供的空调器室内机，因此，本发明提供的空调器室内机具有上述任一实施例提供的蒸发器流路结构1，或如上述任一实施例提供蒸发器，或如上述任一实施例提供的空调器室内机的全部有益效果，在此不一一列举。
本发明提供的蒸发器流路结构1对相关技术进行改进，由于空调器的冷量与换热器的长度即换热面积及循风量有差，而实际上空调器室内机的尺寸和空间有限，如果不改变换热器的内部结构来增加换热面积只能是通过背管或者加长加宽空调器室内机的尺寸进行解决，而本发明是通过改变换热器的内部结构，即改善蒸发器流路结构1的翅片14孔间距与前后蒸的管间距来增加换热面积，同时空调器室内机的换热器流程的设计与空调器室内机的进风面积及风道有关，换热器流程的设计会影响换热器的分流状况，继而也会影响换热器的换热量、整机能效及凝露的产生情况；如图1至图5所示，由于空调器室内机换热器不是光滑的弧形蒸发器，各折蒸发 器风速分布并不均匀，制冷剂在进入蒸发器流路结构1的各流路之前可能出现汽液分层或者汽液两相混合不均，从而不能均匀地进入蒸发器流路结构1的各流路中，导致部分流路液态制冷剂偏多，蒸发不完全，另一部分流路汽态制冷剂偏多，蒸发过热问题严重。如果各流路结构不合理极易造成蒸发器出口偏流过大，会影响整机系统的可靠性。如图6所示：通过改变换热器的翅片14孔间距与前后蒸的管间，常规的翅片14孔间距在21mm，而本发明采用在18mm至21mm之间的间距范围进行设置孔间距，来增大换热器的面积，同时降低了换热器的冷媒压损，并根据空调器室内机换热器的风量不均匀的情况，采用四进四出的方案来提升换热器的效率，并且，采用等程与不等程的流路进行组合，有利于变工况的流路稳定，不会出现由于冷媒泄露问题导致供液量少而出现蒸发器各个流路出流口温差较大产生凝露及吹水等相关问题。
采用本发明提供的蒸发器流路结构1或蒸发器或空调器室内机的空调器分液达到了最好效果，能力达到最优，能够采用现有技术中一匹的空调内机尺寸，满足了二匹的性能指标，合理的管路布置也避免了此类型蒸发器在高湿度条件下工作时的吹水的凝露问题，经实测，采用本发明提供的蒸发器流路结构1或蒸发器或空调器室内机的空调器，制冷能力明显提升，制冷能力由原来与一进两出3500W的能力，提升到5000W的能力水平，同时，其它工况的能力点也均达到二匹的性能要求。
综上所述，本发明提供的蒸发器流路结构1、蒸发器、空调器室内机及空调器，通过U管10与半圆形连接管12连接，并穿设于翅片14上形成四路流路，进而冷媒将由四进四出的流路进行换热，减少了冷媒的行程，进而提升了换热效率，同时，由于换热器的风量无法做到完全均匀，而四路流路能够根据换热器各处风量的差异进行设置，能够进一步地提升换热效率，进而提升了空调器换热效率，因此，实现了在保证空调器体积小巧的情况下，提升了空调器的性能，提升了用户的使用体验。
