背景技术
现有制冷装置的制冷系统一般包括：压缩机、冷凝器、毛细管、蒸发器等，各部件通过制冷管路连接形成一个密封系统，制冷剂在密封系统内发生气液变化以实现制冷作用。对于整体系统来说，密封性至关重要，一旦制冷剂泄漏，不仅影响制冷性能，还可能带来一定的安全隐患。
目前制冷系统中，制冷管路之间普遍采用火焰钎焊密封，该工艺方式对操作人员有高水平要求，在生产过程中属于特岗，但生产线一般都由多名员工作业，不能保证产品质量稳定性和一致性，更重要的是焊接需要使用火种，有一定的安全隐患。

本实施例提供一种制冷管路，该制冷管路包括第一管路110、第二管路120和密封装置130。该制冷管路应用于制冷设备，制冷设备可以是冰箱、冰柜等。
如图1所示，第二管路120套设于第一管路110的对接处，密封装置130包覆于第一管路110和第二管路120的对接处。如图1所示，在本实施例中，第一管路110和第二管路120为圆筒状，但仅为示例性的，第一管路110和第二管路120的形状不作具体限定。在本实施例中，第二管路120的内径比第一管路110的外径略大，但仅为示例性的，第一管路110和第二管路120的尺寸不作具体限定，但是第二管路120对接端的内径与第一管路110对接端的外径相同或者略大。
密封装置130包括两个密封件132，两个密封件132设置为能够适配扣合以至少形成储胶腔131，储胶腔131用于包覆于第二管路120的对接处。在本实施例中，如图1至图3所示，密封件132的材质为塑料的，两个密封件132为一体成型的，其中一个密封件132能相对另一个密封件132翻转。每个密封件132均通过在塑料薄板处形成半球状的腔体和凹槽134方式制备得到。两个密封件132向扣合时，两个半球状的腔体相对合形成储胶腔131。其中一个密封件132的凹槽134容置于另一个密封件132的凹槽134内以使两个密封件132相扣合，这种密封件132的结构简单易制备、质量较轻、成本较低。很显然，上述密封件132仅为示例性的，并不是唯一的，例如，两个密封件132可以是互相独立的，两个密封件132可以通过其他结构实现扣合。
储胶腔131开设有用于注胶的开口133，密封装置130与第一管路110和第二管路120之间注满密封胶。储胶腔131上的开口133可以是任意一个密封件132上的半球状的腔体开设有开口133，密封装置130和第一管路110之间注满密封胶，密封装置130和第二管路120之间也注满密封胶，以将第一管路110和第二管路120密封起来。
在其他一些实施例中，如图1至图3所示，两个密封件132设置为能够适配扣合成型为依次相连的第一圆筒135、储胶腔131和第二圆筒136；第一圆筒135、储胶腔131和第二圆筒136依次包覆于第一管路110、对接处和第二管路120；第一圆筒135的内径与第一管路110的外径相适配，第二圆筒136的内径与第二管路120的外径相适配。第一圆筒135的内径与第一管路110的外径相适配、第二圆筒136的内径与第二管路120的外径相适配，也即第一圆筒135的内壁紧贴第一管路110的外壁，第二圆筒136的内壁紧贴第二管路120的外壁，防止密封胶从储胶仓内流出，造成浪费以及环境污染。
在其他一些实施例中，如图1至图3所示，每个密封件132包括一个塑料板，塑料板具有依次相连的第一半圆筒、半腔体和第二半圆筒。在本实施例中，塑料板在注塑成型时形成平面的板体以及在平面的板体中间凹陷形成的第一半圆筒、半腔体和第二半圆筒。两个密封件132相扣合时，两个半腔体相对合形成储胶腔131，两个第一半圆筒相对合形成第一圆筒135，两个第二半圆筒相对合形成第二圆筒136。也即，两个密封件132相扣合时，其中一个塑料板上的第一半圆筒、半腔体和第二半圆筒与另一个塑料板上的第一半圆筒、半腔体和第二半圆筒依次相对合形成依次相连的第一圆筒135、储胶腔131和第二圆筒136。这种密封件132的结构简单，易成批制备、成本低、重量轻。
在其他一些实施例中，如图1至图3所示，两个塑料板上均具有至少一个凹槽134，其中一个塑料板上的凹槽134卡进另一个塑料板的凹槽134内以使两个密封件132相扣合。凹槽134的数量不作具体限定，可根据具体工况设定，密封件132之间通过凹槽134实现扣合，结构简单，易制备。
在其他一些实施例中，如图1至图3所示，储胶腔131的形状为球状，对接处位于储胶腔131的中间位置。储胶腔131的形状为球状，储胶腔131位于对接处，能够使得对接处的密封胶最多，使得第一管路110和第二管路 120的密封效果最好。对接处位于储胶腔131的中间位置可以进一步提高密封效果。
在其他一些实施例中，密封装置130的材质透明以观察密封胶的状态。密封装置130的材质为透明状，透过透明的密封装置130可以观察密封胶内有没有气泡，储胶仓有没有注满，密封胶有没有外泄等。在其他一些实施例中，密封胶内可以加入一些颜料以便观察。
在其他一些实施例中，如图4至图5所示，第一管路110的管壁沿其径向凸起以形成至少一个第一密封环，第二管路120的管壁沿其径向凸起以形成至少一个第二密封环，当第二管路120套设于第一管路110的对接处时，第一密封环容置于与其对应的第二密封环内。由于第一密封环和第二密封环沿管路的径向凸出，因此，管路内制冷剂的流动方向与第一密封环和第二密封环垂直。第一密封环和第二密封环对外泄的制冷剂有一定的阻挡作用，有效防止制冷剂外泄。
在其他一些实施例中，第一密封环的个数为多个，沿第一管路110的轴向分布；第二密封环的个数为多个，沿第二管路120的轴向分布。如图4至图5所示，第一密封环的个数为3个，第二密封环的个数也为3个。这可以有效的阻止制冷剂外泄，也阻止空气进入。
如图6所示，本实施例提供一种制冷管路的密封方法，其包括：
步骤S602：将密封装置130包覆于第一管路110的对接处，其中，密封装置130至少具有储胶腔131，储胶腔131用于包覆于第一管路110的对接处。
密封装置130的具体形状不作限定，上述实施例中密封装置130的形状仅为示例性的，以上述密封装置130为例。将密封装置130扣合至少形成储胶腔131，储胶腔131位于第一管路110的对接处。
可选地，将密封装置130包覆于第一管路110的对接处，且至少对接处的端部伸出密封装置130。对接处的端部伸出密封装置130，可以有效避免密封胶封堵第一管路110，避免第一管路110的堵塞。对接处伸出的量不作具体限定，至少端部伸出即可。在一些可选的实施例中，第一管路110依次设置多个第一密封环，对接处可从密封装置130内伸出至最靠近端部的第一密封环处，第一密封环能进一步阻止密封胶渗漏至第一管路110，避免第一管路110的堵塞。
步骤S604：从储胶腔131的开口133处向密封装置130内注入密封胶。
此时，由于储胶腔131包覆于第一管路110的对接处，向储胶腔131内注入密封胶，第一管路110的对接处会沾满密封胶，因此，该步骤中向储胶腔131内注入密封胶以使第一管路110的对接处涂覆密封胶。第一管路110的对接处涂满密封胶，第二管路120套设于第一管路110的密封效果更好，防止制冷剂外泄。
可选地，旋转密封装置130以使第一管路110的表面涂满胶水。旋转密封装置130可有效避免密封装置130内存在的气泡导致第一管路110表面没有涂满胶水，也即可避免第一管路110表面漏涂密封胶水。
步骤S606：将密封装置130向远离对接处的方向移动以露出对接处。
由于第一管路110的对接处位于储胶腔131内，密封装置130向远离对接处的方向移动，这样可以露出对接处，以方便第二管路120套设于对接处上。
步骤S608：将第二管路120套设于对接处上。
此时，第二管路120和第一管路110的对接处之间充满密封胶，使得第一管路110和第二管路120密封效果良好。
可选地，向第二管路120套设于对接处施加压力以使第一管路110不从第二管路120中滑出。第二管路120套设于第一管路110后，第一管路110和第二管路120之间的密封胶尚未固化，第一管路110和第二管路120之间仍然会发生相对位移。向第二管路120的对接处施加压力可将第二管路120固定于第一管路110处，避免在后续的操作步骤中第二管路120相对第一管路110移动。
步骤S610：将密封装置130向对接处的方向移动以使密封装置130包覆于第二管路120与第一管路110的对接处。
将密封装置130移动至第二管路120与第一管路110的对接处，以使密封装置130和第一管路110之间充满密封胶，密封装置130和第二管路120之间充满密封胶，进一步对第一管路110和第二管路120的对接处进行密封。
可选地，再次从储胶腔131的开口133处向密封装置130内注入密封胶。
由于密封装置130会相对第一管路110和第二管路120来回移动，可能会导致密封装置130内的密封胶损失，再次向密封装置130内注入密封胶，进一步保证第一管路110和第二管路120的密封效果。
综上，上述制冷管路制备方法制备的制冷管路，第一管路110和第二管路120之间充满密封胶；密封装置130和第一管路110之间充满密封胶，密封装置130和第二管路120之间充满密封胶。第一管路110和第二管路120的对接处获得双重的密封防护，密封效果良好。本发明的制冷管路采用密封装置130和密封胶密封，解决目前火焰钎焊密封不安全、操作要求高等技术问题。
如图7所示，本实施例的密封方法还可以按照如下步骤实施。
步骤S702：将密封装置130包覆于第一管路110的对接处，至少对接处的端部伸出密封装置130。
步骤S704：从储胶腔131的开口133处向密封装置130内注入密封胶。
步骤S706：旋转密封装置130以使第一管路110的表面涂满胶水。
步骤S708：将密封装置130向远离对接处的方向移动以露出对接处。
步骤S710：将第二管路120套设于对接处上。
步骤S712：向第二管路120套设于对接处施加压力以使第一管路110不从第二管路120中滑出。
步骤S714：将密封装置130向对接处的方向移动以使密封装置130包覆于第二管路120与第一管路110的对接处。
步骤S716：再次从储胶腔131的开口133处向密封装置130内注入密封胶。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
