相关申请
本申请要求2021年12月16日申请的，申请号为202123178188.3，发明名称为“一种储液器”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

背景技术
储液器是制冷设备的重要部件，安装在蒸发器与压缩机之间，起到贮藏、气液分离、过滤、消音和制冷剂缓冲的作用。

然而，上述结构的储液器在工作时，滤网组件对冷媒的流动会产生阻力，从而影响压缩机的运转性能；而且滤网组件的面积较大，其不仅材料成本高，而且还会因生产或者装配的误差而导致该储液器上出气管直接顶死滤网组件，或者出气管与滤网组件之间的装配距离不符合要求的情形发生，而上述情形一旦发生会影响压缩机的性能，甚至造成压缩机不启动。

除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本申请。本文所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1所示，本申请一实施例所提供的储液器100，包括筒体10、第一端盖20、第二端盖30、进气管40及出气管50。其中，第一端盖20及第二端 盖30安装于筒体10的两端，且第一端盖20、筒体10及第二端盖30配合并形成有内腔101。
进气管40的一端设置为出管口401，进气管40安装于第一端盖20上并通过出管口401与内腔101连通。出气管50的一端设置为进管口501，且出气管50安装于第二端盖30上，并且出气管50的进管口501伸入内腔101内并与内腔101连通，使得该储液器100工作时，进气管40能够将冷媒导入至内腔101内，内腔101内的气态冷媒能够通过出气管50向外排出。
在一些实施例中，压缩机200长期运转，其内部会有一定的润滑油进入储液器100的筒体10内。沿着垂直于筒体10轴线的方向，出管口401与进管口501错位设置；出气管50上开设有回油孔102，且出气管50在回油孔102所在的位置设置有滤网组件60，用以过滤润滑油内的杂质。如此设置，沉淀在筒体10底部的润滑油通过回油孔，通过压缩机200的吸力作用，又通过储液器100的出气管50进入压缩机200内，保证对压缩机200起到良好的润滑保护作用。
可以理解，本实施例的储液器100通过将出管口401与进管口501错位设置，能够避免由进气管40导入的液态冷媒直接流入出气管50，进而避免该储液器100连接压缩机200并工作时，因液态冷媒在压缩机200内发生液击而造成压缩机200损坏的情形发生。同时通过出管口401与进管口501错位设置及回油孔102上设置滤网组件60，以替代相关技术中直接在进气管的排气管口设置滤网组件，使得该储液器100工作时冷媒在储液器100内流通受到的阻力能够减小，同时具有降低该储液器100的材料成本，提高连接储液器100的压缩机200运转性能的作用。
具体地，出管口401与进管口501相对于筒体10偏心设置，以此具体实 现该进气管40上出管口401及出气管50上进管口501在该储液器100上的结构设置。当然，出管口401及进管口501不局限于两者均相对于筒体10偏心设置，对本领域技术人员来说，可将出管口401及进管口501择一相对于筒体10偏心设置，在此就不展开阐述。
进一步地，该出管口401与进管口501对称地设置于筒体10上圆心线的两侧，使得该储液器100上出管口401与进管口501之间的间距能够足够大，以此确保由进气管40导入的液态冷媒不会直接地流入出气管50。
其中，本实施例的第一端盖20包括第一平面安装部21，进气管40通过第一平面安装部21安装于第一端盖20上，以此具体实现进气管40在该第一端盖20上的装配连接，利用第一平面安装部21的结构特性，具有便于将该进气管40装配至第一端盖20上的作用。
如图2所示，本实施例的进气管40包括锥管部41，锥管部41插入第一平面安装部21内，并与第一平面安装部21焊接固定，以此具体实现进气管40与第一平面安装部21之间的装配连接，可利用锥管部41进行导向，以进一步便于将该进气管40装配至第一平面安装部21上。
在一些实施例中，第二端盖30包括第二平面安装部31，出气管50通过第二平面安装部31安装于第二端盖30上，以此具体实现出气管50在该第二端盖30上的装配连接，利用第二平面安装部31的结构特性，具有便于将该出气管50装配至第二端盖30上的作用。
如图3所示，该出气管50包括直管51和弯管52，直管51包括扩孔连接部511，直管51通过扩孔连接部511分别与弯管52及第二平面安装部31进行焊接固定，以此具体实现该出气管50的结构设置，并实现该出气管50上直管51及弯管52在第二平面安装部31上的装配连接。
其中，直管51至少部分位于内腔101内，且回油孔102设置在直管51靠近第二端盖30的侧壁上，以此具体实现该回油孔102在出气管50上的结构设置。
另外，本实施例的出管口401与进管口501之间形成有预设间隙，以此具体实现该储液器100的一个实施例。可选的，沿筒体10的轴线方向，出管口401与进管口501沿之间形成有预设间隙。预设间隙的设置可以避免液态冷媒流入进管口501中，造成液态冷媒在压缩机内发生液击而损坏压缩机。
如图3所示，该滤网组件60包括连接套筒61和滤网62，连接套筒61的一端插设在回油孔102上，以将连接套筒61安装于出气管50上，滤网62安装于连接套筒61的另一端上，滤网62的过滤面积大于回油孔102的流通面积，以此具体实现该滤网组件60的结构设置；同时将滤网62的过滤面积设置为大于回油孔102的流通面积，以便于润滑油途经该滤网62的过滤并进入至回油孔102内。
可以理解，本申请的储液器100用回油孔102上滤网组件60替代相关技术中设置于出管口401及进管口501之间的滤网，在满足过滤润滑油内杂质的基础上，具有降低材料成本的技术效果，而且可使冷媒在该储液器100的内腔101内的流通不受滤网组件60的阻碍，减少流通阻力，不仅能够提高连接该储液器100的压缩机200的运转性能，而且也规避了该储液器100在装配时，由出气管50与滤网组件60发生顶死或者距离不符合要求而引发压缩机200运行性能差的问题。
参阅图4，本申请还提供了一种制冷设备300，包括压缩机200和如上任一实施例所述的储液器100，所述压缩机200连接所述储液器100，气液混合流体在储液器100内进行气液分离，分离后的气体进入压缩机200内进行压 缩。
应用储液器100后，由于储液器100通过将出管口401与进管口501错位设置，能够避免由进气管40导入的液态冷媒直接流入出气管50，进而避免该储液器100连接压缩机200并工作时，因液态冷媒在压缩机200内发生液击而造成压缩机200损坏的情形发生。同时通过出管口401与进管口501错位设置，该储液器100工作时冷媒在储液器100内流通受到的阻力能够减小，进一步提高了连接储液器100的压缩机200运转性能，保证制冷设备300的稳定运行。
以上实施方式的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施方式中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
本技术领域的普通技术人员应当认识到，以上的实施方式仅是用来说明本申请，而并非用作为对本申请的限定，只要在本申请的实质精神范围内，对以上实施方式所作的适当改变和变化都落在本申请要求保护的范围内。
