本申请通过在第一安装孔11的内壁设置定位部12，通过定位部12实现过滤单元3的定位，防止油分离器100在使用过程中过滤单元3松动和/或移位而导致杂质进入回油管2内，以免造成压缩机损坏；相比于相关技术中过滤结构复杂的安装定位的方式，本申请对过滤单元3的进行定位安装的方式更加简单，有效降低油分离器100的制造难度和制造成 本，大幅度提高油分离器100的制造效率。
其中，定位部12可以是设置于第一安装孔11的内壁上的凸起结构，凸起结构更加简单，进一步有利于降低油分离器100的制造难度和制造成本，当然也可以通过在第一安装孔11处设置缩口形成台阶，该台阶形成以上所述的定位部12，台阶结构同样简单，大幅度降低油分离器100的制造难度，当然在其他实施例中，定位部12的具体结构不局限与以上所述或图中所示，定位部12也可以是能够与过滤单元3相互配合卡接的结构。
可选的，筒体1为不锈钢筒体1，且一体成型设置，不锈钢筒体1一体成型，减少焊接，提高工作效率。其中，目前油分离器100的筒体1通常采用铜材料，而本申请可选的采用不锈钢材料制造筒体1，不锈钢材料相比于筒材料硬度更高，不易变形，耐腐蚀，且价格更低，采用不锈钢材料可大幅度的降低生产成本。
请参阅图1-3，可选的，回油管2伸入第一安装孔11内的一端抵靠于过滤单元3，通过回油管2与定位部12配合实现过滤单元3的固定，固定方式简单，且无需增加额外的固定结构，有利于降低制造成本，提高制造效率。另外，在组装时，只需回油管2与过滤单元3抵靠，不会增加焊口，组装效率高。当然在其他实施例中，也可以通过在回油管2和定位部12之间设置固定结构，通过固定结构与定位部12夹紧固定过滤单元3，进一步防止过滤单元3松动。
请参阅图1、2，过滤单元3包括安装座31以及过滤网33，装配时安装座31朝向筒体1内部的一端抵靠于定位部12上，过滤网33安装于安装座31，安装回油管2后，回油管2伸进第一安装孔11内的一端与安装座31的另一端抵靠，从而实现安装座31沿筒体1轴向的限位，而安装座31的侧壁与第一安装孔11的侧壁抵靠，实现安装座31沿筒体1径向的限位。其中过滤结构的结构简单，易于获得，有利于降低制造成本，当然在其他实施例中，过滤单元3的具体结构不局限于以上所述。
可选的，参阅图2、3，安装座31上开设有安装槽32，过滤网33的一端固定于安装槽32内，由安装槽32对过滤网33的一端进行限位，安装方式简单，无需设置额外的固定结构，有效降低过滤单元3的制造成本，降低过滤网33的装配难度。当然在其他实施例中，过滤网33安装于安装座31上的方式不局限于以上所述或图中所示，例如也可以采用粘接或焊接的方式安装过滤网33，又例如通过其他的固定结构将过滤网33固定于安装座31上。
请继续参阅图2，可选的，过滤网33朝向筒体1内部的一端设置成半球形，半球形状有利于增加过滤网33的有效过滤面积，并且，当过滤网33过滤出油液内的杂质时，半球形的弧面可以将杂质引导至过滤网33的边缘，以免杂质堆积在过滤网33上，更好的避免 过滤网33堵塞。
进一步地，参阅图1、2，回油管2伸入第一安装孔11的一端设有扩口段21，扩口段21伸入第一安装孔11内，并与筒体1连接，通过设置扩口段21，装配时扩口段21与第一安装孔11过盈配合，增强第一安装孔11和回油管2之间的气密性，防止油液从第一安装孔11和回油管2之间泄漏。另外，扩口段21靠近过滤单元3的一端与过滤单元3抵靠，将过滤单元3固定于定位部12和回油管2之间，进一步防止过滤单元3松动。
进一步地，扩口段21与筒体1焊接连接，实现回油管2的装配固定，防止回油管2松动。
另外，参阅图1，回油管2远离第一安装孔11的一端设置有铜接头23，由于不锈钢材料的硬度更高且价格更低，可选的，回油管2采用不锈钢材料制成，而在制冷技术领域，一般空调系统内的连接管为铜材料，铜材料与不锈钢材料的焊接特性相差很大，导致不锈钢材质的回油管2与空调系统内的连接管焊接在一起的工艺难度较大，使用时装配难度较高，因此，通过在回油管2远离第一安装孔11的一端设置铜接头23与空调系统内的连接管焊接，有利于降低焊接难度，提高油分离器100的装配效率。
另外，请参阅图1、5，可选的，回油管2连接铜接头23的管内壁设置凸部22，凸部22对铜接头23起到定位作用，限定铜接头23伸入回油管2内的长度，具体的，回油管2先缩口后接着再扩口形成朝向管内凸出的凸部22，形成方式简单，降低加工难度。当然在其他实施例中，凸部22的形成方式不局限于以上所述，例如也可以直接在管内壁上设置凸起结构。
请继续参阅图1，本申请提供的油分离器100还包括安装于筒体1上的出气管4，油分离器100内的气相冷媒从出气管4输出。其中，筒体1的顶部开设有第二安装孔13，出气管4的一端从第二安装孔13伸入筒体1内。
进一步地，出气管4包括第一段41以及第二段42，第一段41的一端从第二安装孔13伸入筒体1内，另一端位于筒体1外，且第一段41的另一端具有缩口部411；第二段42的一端伸入缩口部411，并与第一段41连接，通过设置缩口部411与第二段42的一端过盈配合连接，使得第一段41与第二段42连接更稳固，提高第二段42与第一段41之间的气密性。另外，第二段42的材料为铜材料，便于第二段42与空调系统内的连接管焊接，有利于降低焊接难度，提高油分离器100的装配效率。
请继续参阅图1、4，油分离器100还包括消音板5，消音板5安装于筒体1内，并将筒体1分隔为第一腔室16和第二腔室17，且消音板5上开设有多个连通第一腔室16和第二腔室17的消音孔51；出气管4伸入第二安装孔13的一端经第一腔室16并穿设消音板 5延伸至第二腔室17，通过消音板5固定出气管4，防止出气管4晃动而产生噪音。
请参阅图4，筒体1的内壁上形成限位槽15，消音板5的周侧卡设于限位槽15内，实现消音板5的固定，当然在其他实施例中，消音板5安装固定的方式不局限于以上所述，例如也可以在筒体1的内壁上设置卡接结构，消音板5与卡接结构配合卡接实现固定。
请继续参阅图1，本申请提供的油分离器100还包括安装于筒体1上的进气管6，筒体1的侧壁上开设有第三安装孔14，进气管6的一端安装于第三安装孔14内，且与筒体1内部连通设置，气液两相混合的冷媒从进气管6输入油分离器100内进行油液分离。
可选的，第三安装孔14的轴线与筒体1的轴线不相交，换言之，第三安装孔14偏心设置，作业时筒体1高速旋转，使得从进气管6进入筒体1内的气液两相混合的冷媒和油液在离心力的作用下沿着筒壁转动分离，使得液态冷媒挥发形成气态冷媒，气态冷媒从出气管4输出，而油液由于重力的作用沿着筒壁下降沉积在筒体1内。当然在其他实施例中，第三安装孔14的轴线也可以与筒体1的轴线相交设置。
进一步的，进气管采用为不锈钢材料制作，进气管6远离第三安装孔14的一端设置有铜套61，通过铜套61与空调系统内的铜质连接管焊接，有利于降低焊接难度，提高油分离器100的装配效率。
请继续参阅图1，油分离器100还包括加强板7，加强板7套设并安装于进气管6安装于第三安装孔14的一端，且加强板7位于筒体1的外侧，加强板7固定于筒体1上，且加强板7朝向筒体1的侧壁的一面与筒体1的侧壁贴合，加强板7能够增加与筒体1的接触面积，有效增强进气管6与筒体1的连接强度。
本申请还提供一种空调系统，包括压缩机和以上所述的任意一种油分离器100，油分离器100的回油管2与压缩机相连接，具体的，压缩机的连接管路与回油管2的铜接头23焊接相连。本申请提供的空调系统可以在更低的成本下，实现对压缩机油液的良好过滤，保证压缩机的安全，同时提高该空调系统的制作效率。
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。
