可选地，在一些实施例中，发明人通过大量试验，得出当第一间隙L1的范围为0.1mm～0.25mm，第二间隙L2的范围为0.1mm～0.3mm时，该管路连接装置300既很好地阻止其它物质进入第一通道111和第二通道121内，从而保证换热系统的换热性能，例如密封件13(例如石墨垫片)不会从第一间隙L1挤出而流到第一通道111和第二通道121。同时，第一连接件11和第二连接件12的配合较松，不会出现第一连接件11和第二连接件12配合卡 死的问题，从而有利于管路连接装置300的拆装。
可选地，在一些实施例中，第一间隙L1的范围为0.15mm～0.25mm，第二间隙L2的范围为0.15mm～0.25mm时，该管路连接装置300既保证了密封件13(例如石墨垫片)不会被挤出到第一间隙L1而流到第一通道111和第二通道121，从而保证换热系统的换热性能。同时，第一连接件11和第二连接件12的配合也较松，使得第一连接件11和第二连接件12的拆装也较为轻松。
可选地，在一些实施例中，第一间隙L1的范围为0.1mm～0.2mm，第二间隙L2的范围为0.1mm～0.2mm时，该管路连接装置300既保证了密封件13(例如石墨垫片)不会被挤出第一间隙L1而流到第一通道111和第二通道121，从而保证制冷系统的制冷性能。同时，第一连接件11和第二连接件12的配合也松，使得第一连接件11和第二连接件12的拆装也较为轻松。
可选地，在一些实施例中，第一间隙L1的范围为0.05mm～0.15mm，第二间隙L2的范围为0.05mm～0.15mm时，该管路连接装置300既保证了密封件13(例如石墨垫片)不会被挤出第一间隙L1而流到第一通道111和第二通道121，第一连接件11和第二连接件12的拆装也较为轻松。
此外，可选地，在一些实施例中，当第一间隙L1的范围为0.15mm～0.25mm，第二间隙L2的范围为0.25mm～0.3mm时，第二间隙L2处可能会有少量密封件13(例如石墨垫片)被挤出，而第一间隙L1处不会有密封件13(例如石墨垫片)被挤出，能够很好地保证管路连接装置300的密封性，且第一连接件11和第二连接件12的配合松，容易拆装。
可选地，在一些实施例中，当第一间隙L1的范围为0.25mm～0.3mm，第二间隙L2的范围为0.25mm～0.3mm时，在第一间隙L1和第二间隙L2处均可能会有少量密封件13(例如石墨垫片)被挤出，但被挤出的少量的密封件13的碎屑不会进入第一通道111和第二通道121中，因而不会影响换热系统的性能。且第一间隙L1和第二间隙L2选用该范围，第一连接件11和第二连接件12的配合松，容易拆装。
可选地，在一些实施例中，当第一间隙L1的范围为0～0.1mm，第二间隙L2的范围为0～0.1mm时，第一间隙L1和第二间隙L2处均无密封件被挤出，因而，第一间隙L1处不会有密封件13的碎屑等进入第一通道111和第二通道121中，从而可避免由于其它物质进入管路内而导致换热系统堵塞的现象发生，有利于保证换热系统的换热性能。
进一步地，请结合图2至图6所示，在一些实施例中，第一连接件11设有位于抵接部113外周侧的第二槽部114。第二槽部114包括第二容纳槽1140、位于第二容纳槽1140内侧的内壁面1141、位于第二容纳槽1140底部的底壁1143及位于第二容纳槽1140外侧的外壁面1142。抵接部113的外壁面为第二槽部114的内壁面1141。相应地，第二连接件12设有位于第一容纳槽1240外周侧的第二隔离部125。第二隔离部125包括外壁面1252及端面1251。该第二隔离部125的端面1251与上述第一隔离部123的端面1231可位于同一平面，也可不位于同一平面。第一隔离部123的端面1231高于密封件13的高度，能够使得密封件13完全容纳于第一容纳槽1240，避免密封件13直接暴露于第二通道121内。第一槽部124的外壁面(即第二侧壁1242)为第二隔离部125的内壁面。至少部分第二隔离部125设于第二容纳槽1140内。第二隔离部125的端面1251可与第二槽部114的底壁1143抵接，也可不与第二槽部114的底壁1143接触。本专利申请对此不做限定，可根据具体应用环境进行设置。
进一步地，发明人研究发现，抵接部113的厚度如果太小，会使得抵接部113与密封件13的接触面积变小，导致密封效果变差；而如果抵接部113的厚度太大，则会导致安装螺栓的预紧力增大，密封难度加大。关于螺栓，在下述实施例中会详细描述，具体可参见下述相关描述。请结合图4和图6所示，在一些实施例中，发明人通过大量试验得出，抵接部113的厚度D1为1.5mm～3mm，第一容纳槽1240的宽度D2为1.7mm～3.55mm时，能够很好的保证管路连接装置300密封性的同时，还便于安装。
进一步地，请结合图6所示，在一些实施例中，第一隔离部123的厚度 D3为1mm～2.5mm。
请接续结合图6所示，在一些实施例中，第二隔离部125的厚度D4为1mm～2.5mm。

第二通道121包括靠近第一连接件11的通道主体1210及远离第一连接件11的管道容纳部1220。该管道容纳部1220的径向尺寸大于通道主体1210的径向尺寸，以便于管道容纳部1220内安装及固定另一管道。第二通道121包括靠近第一连接件11的开口1211。上述第一隔离部123的端面1231位于开口1211的外周侧，并与开口1211位于同一平面。
进一步地，请继续参考图1至图6所示，在一些实施例中，第一连接件11包括朝向第二连接件12的第一端面1121，第二连接件12包括与第一端面1121相对的第二端面1221。抵接部113的端面相对于第一端面1121更远离第二连接件12。第一隔离部123的端面相对于第二端面1121更靠近第一连接件11。即，抵接部113凹设于第一连接件11，第一隔离部123凸设于第二连接件12。
在另一些实施例中，请参照图7所示，第一连接件11包括朝向第二连接 件12的第一端面1121，第二连接件12包括与第一端面1121相对的第二端面1221。其中，抵接部113凸出第一端面1121设置，第一容纳槽1240由第二连接件12的部分自第二端面1221向内凹陷所形成。即，抵接部113凸设于第一连接件11，第一隔离部123凹设于第二连接件12。
进一步地，第一连接件11包括第一通孔116，第二连接件12包括与第一通孔116相对的第二通孔126。
相应地，管路连接装置300包括紧固装置。在一些实施例中，紧固装置包括螺栓和螺母，螺栓可穿过第一通孔116和第二通孔126，螺母紧固螺栓。在另一些实施例中，紧固装置包括螺栓。第一通孔116设置有内螺纹，螺栓自第二通孔126远离第一通孔116的一端穿过第二通孔126而延伸入第一通孔116，而与第一通孔116的内螺纹配合，以实现第一连接件11和第二连接件12的紧固。当然，也可在第二通孔126的内壁设置内螺纹(可结合图7所示)，螺栓14自第一通孔116远离第二通孔126的一端穿过第一通孔116而延伸入第二通孔126，而与第二通孔126的内螺纹配合，以实现第一连接件11和第二连接件12的紧固。本专利申请对此不做限定，可根据具体应用环境进行设置。
进一步地，第一连接件11和第二连接件12至少其中之一设置有台阶部，以使靠近螺栓一侧的密封面和远离螺栓一侧的密封面受到的预紧力一致，从而实现该管路连接装置300的均匀密封。结合图2至图6，在一些实施例中，第二连接件12设有台阶部128，台阶部128设于第二通道121的相对一侧，即第二通孔126设于台阶部128与第二通道121之间。而在另一些实施例中，如图7所示，第一连接件11设有台阶部118，第一通孔116设于台阶部128与第一通道111之间。
图8至图13揭示了本专利申请第三实施方式的一种管路连接装置300(请参图9所示)，其包括第一连接件11、第二连接件12、密封件13以及将第一连接件11与第二连接件12相对固定的紧固装置。密封件13为石墨垫片。请参图11至图13所示，在本实施方式中，紧固装置为螺栓14。
第二连接件12设有面向第一连接件11的第二端部122、自第二端部122向外凸出且延伸超出第二端部122的第一隔离部123、以及沿轴向方向贯穿第二连接件12的第二通道121。第二通道121轴向贯穿第一隔离部123。第二连接件12设有第一槽部124，第一槽部124设有自第二端部122向内凹设且用以收容密封件13的第一容纳槽1240。第一容纳槽1240环设于第一隔离部123的外周。第一槽部124包括位于第一容纳槽1240内的底壁1243，第一容纳槽1240轴向贯穿第二端面1221。密封件13沿轴向方向的投影与第二端面1221沿轴向方向的投影重叠，或者密封件13沿轴向方向的投影落入第二端面1221所在平面内。在本实施方式中，第一槽部124仅设置有且仅有一个第一容纳槽1240。
请结合图8、图10及图12所示，当第二连接件12与第一连接件11处于自由状态，即未通过紧固装置进行固定时，密封件13沿第二通道121的轴向方向的原始高度高于第一容纳槽1240的深度h。第一容纳槽1240沿第二通道121的径向方向的径向深度大于或者等于密封件13的径向厚度。
第一连接件11设有与第二端部122对接的第一端部112、自第一端部112向外凸出的抵接部113、用以收容第一隔离部123的通道容纳部1110以及轴向贯穿第一连接件11的第一通道111。第一通道111与通道容纳部1110轴向连通。在本实施方式中，第一端部112仅设置有且仅有一个抵接部113。可选地，第一通道111的内径与第二通道121的内径大致相等。第一隔离部123的径向外径等于或者小于通道容纳部1110的径向内径；如此设置，以更好的达成第二连接件12与第一连接件11之间的连接密封。
抵接部113环设于通道容纳部1110的外周。抵接部113的断面形状与密封件13的断面形状一致；换言之，抵接部113与密封件13接触的一端的形状和密封件13与抵接部113接触的一端的形状相匹配。密封件13抵接在底壁1243和第一端面1121之间。如此设置，能够确保抵接部113稳定抵压收容在第一容纳槽1240内的密封件13，并确保密封件13被压缩至全部收容于第一容纳槽1240内，从而避免石墨垫片被压溃掉出而产生的隐患。在本实施 方式中，第二连接件12与第一连接件11之间仅通过一个抵接部113与一个第一容纳槽1240相互卡持配合达成固定，减少了第二连接件12与第一连接件11之间的配合面，改善第二连接件12与第一连接件11卡死的问题。
请结合图9、图13及图14所示，当第二连接件12与第一连接件11通过紧固装置(例如螺栓14)进行固定并达成密封时，第一通道111与第二通道121直接连通。密封件13沿轴向方向被抵接部113抵压，密封件13的高度H等于第一容纳槽1240的深度h。请参图13及图14所示，在专利申请的一些实施方式中，第一容纳槽1240是由第二连接件12的主体形成的。可选地，经过压缩后的密封件13为密度大于1.8g/cm 3的石墨垫片。当然，请参图14所示，在本专利申请管路连接装置的第四实施方式中，也可通过抵接部113将密封件13进一步压缩至密封件13的高度H略小于第一容纳槽1240的深度h。可选地，密封件13的高度H与第一容纳槽1240的深度h的比值为X，其中0.6≤X≤1。抵接部113沿轴向方向延伸的高度M与密封件13的高度H之和大于第一容纳槽1240的深度h。抵接部113的高度M与密封件13的高度H之和小于或者等于抵接部113的高度M与第一容纳槽1240的深度h之和。
在本实施方式中，提供密度在1.4～1.6g/cm 3之间，具有原始高度的石墨垫片，将石墨垫片安装至第一容纳槽1240内，此时石墨垫片沿轴向方向的原始高度高于第一容纳槽1240的轴向深度h(参图8及图12所示)；通过抵接部113沿轴向向下挤压石墨垫片，使得挤压后的石墨垫片成为收容于第一容纳槽1240内的密封件13；此时密封件13的高度H等于或者略小于第一容纳槽1240的深度h，此两种情况都可达成第二连接件12与第一连接件11之间的相对密封。
将密度在1.4～1.6g/cm 3之间的原始石墨垫片压缩为密度大于1.8g/cm 3的石墨垫片时，此时的密封件13在第二连接件12与第一连接件11之间能够达成较好的密封效果。同时，因为仅通过抵接部113与第一容纳槽1240以及第一隔离部123分别相互抵接匹配，仅产生两个配合面，从而降低第二连接件 12与第一连接件11因配合面较多而产生的组装和拆分卡死隐患。
当然，在其他实施方式中，石墨垫片的原始高度也可以为略小于或者等于第一容纳槽1240的深度h。根据石墨垫片的密度不同，通过抵接部113挤压石墨垫片可达成第二连接件12与第一连接件11之间的密封效果。
图15至图17揭示了本专利申请第五实施方式的管路连接装置，本实施方式中的管路连接装置与第三实施方式中的管路连接装置300绝大部分结构相同，故在此不在赘述共同点。本实施方式管路连接装置与第三实施方式的主要区别在于，第二连接件12'的第二端部122'包括朝向第一连接件11'设置的第二端面1221'、凹设于第二端部122'的本体凹槽110'、自本体凹槽110'的部分底壁凸出延伸的第一隔离部123'、承载于第二端面1221'的环形部件5'以及形成于环形部件5'与第一隔离部123'之间的收容空间50'。收容空间50'与本体凹槽110'轴向连通形成收容密封件13'的第一容纳槽1240'，即第一容纳槽1240'是由第二连接件12'的主体以及环形部件5'与第一隔离部123'之间的收容空间50'共同形成的。请参图17所示，密封件13'高度为H'，第一容纳槽1240'深度为h'，本体凹槽110'深度为n，密封件的高度H'等于第一容纳槽1240'的深度h'。密封件13'限定为收容于本体凹槽110'内的第一部分131'及收容于收容空间50'内的第二部分132'。环形部件5'沿轴向方向的高度不小于密封件13'的高度H'与本体凹槽110'的深度n之差。环形部件5'的内径不小于本体凹槽110'的外径。在一种实施方式中，环形部件5'为金属环。本体凹槽110'沿轴向方向的投影全部落入环形部件5'沿轴向方向的投影内。第一连接件11'上的抵接部113'沿轴向向下挤压密封件13'，环形部件5'套接在密封件13'凸出本体凹槽110'的凸起部分上，即环形部件5'套接于第二部分132'的外侧。如此设置，在第三实施方式的基础上，更进一步地优化管路连接装置，当第二连接件12'与第一连接件11'在通过螺栓14'慢慢达成固定密封的过程中，环形部件5'能够降低密封件13'被挤出的风险，从而进一步降低作为密封件13'的石墨垫片被压溃掉出残渣而产生的隐患。在本实施方式中，第二端部122'仅设置有且仅有一个第一容纳槽1240'，第一端部112'仅设置有且仅有 一个抵接部113'，第二连接件12'与第一连接件11'之间仅通过一个抵接部113'与一个第一容纳槽1240'相互卡持配合达成固定，减少了第二连接件12'与第一连接件11'之间的配合面，改善第二连接件12'与第一连接件11'卡死的问题。
图18至图21揭示了本专利申请第六实施方式的管路连接装置，本实施方式中的管路连接装置与第三实施方式中的管路连接装置300绝大部分结构相同，故在此不在赘述共同点。本实施方式管路连接装置与第三实施方式的主要区别在于，第二连接件12”的第二端部122”包括朝向第一连接件11”设置的第二端面1221”、凹设于第二端部122”的本体凹槽110”、自本体凹槽110”的部分底壁1243”凸出延伸的第一隔离部123”以及至少部分收容于本体凹槽110”内的环形部件5”。环形部件5”、第一隔离部123”以及本体凹槽110”的部分底壁1243”之间形成收容密封件13”的第一容纳槽1240”。环形部件5”沿轴向方向的高度不低于密封件13”的高度H”。环形部件5”的外径不大于第一容纳槽1240”的外径。本体凹槽110”沿第二通道121”的径向深度大于或者等于环形部件5”的径向厚度与密封件13”的径向厚度之和。环形部件5”沿轴向方向的投影全部落入本体凹槽110”沿轴向方向的投影内。第一连接件11”上的抵接部113”沿轴向向下挤压密封件13”，环形部件5”套接在密封件13”外侧且环形部件5”至少部分位于第一容纳槽1240”中。如此设置，以使得本体凹槽110”能够将至少部分密封件13”及至少部分环形部件5”收容在内，通过环形部件5”的设置，不但降低了第二连接件12”与第一连接件11”装配卡死的隐患，还能降低石墨垫片被压溃掉出的风险。在本实施方式中，第二端部122”仅设置有且仅有一个第一容纳槽1240”，第一端部112”仅设置有且仅有一个抵接部113”，第二连接件12”与第一连接件11”之间仅通过一个抵接部113”与一个第一容纳槽1240”相互卡持配合达成固定，减少了第二连接件12”与第一连接件11”之间的配合面，改善第二连接件12”与第一连接件11”卡死的问题。
图22至图24揭示了本专利申请第七实施方式的管路连接装置，本实施方式中的管路连接装置与第三实施方式中的管路连接装置绝大部分结构相同， 主要区别在于第二连接件12”'与第一连接件11”'配合连接处。在本实施方式中，管路连接装置包括密封件13”'、将第二连接件12”'与第一连接件11”'相对固定的紧固装置(例如螺栓14”')以及套置于密封件13”'外周的环形部件5”'。
第二连接件12”'设有第二端部122”'以及自第二端部122”'向外凸出的第一隔离部123”'。第二连接件12”'包括朝向第一连接件11”'设置的第二端面1221”'，环形部件5”'、第一隔离部123”'以及部分第二端面1221”'共同形成了收容密封件13”'的第一容纳槽1240”'。密封件13”'套接在第一隔离部123”'上，环形部件5”'套设于第一隔离部123”'的外周。环形部件5”'沿轴向方向的高度不低于密封件13”'的高度H”'。

当第二连接件12”'与第一连接件11”'通过螺栓14”'进行固定并达成密封时，抵接部113”'抵压密封件13”'，密封件13”'沿轴向方向高度等于环形部件5”'的高度。可选地，此时，密封件13”'为密度大于1.8g/cm 3的石墨垫片。当然，在其他实施方式中，抵接部113”'也可进一步抵压密封件13”'，直至密封件13”'沿轴向方向的高度小于环形部件5”'的高度。环形部件5”'的上端部收容于第二容纳槽1140”'内。
请参图2、图8至图24所示，第一连接件11、11'、11”、11”'与第二连接件12、12'、12”、12”'设有相互接触的环形摩擦面119、119'、119”、119”'，环形摩擦面119、119'、119”、119”'的数量不超过两个。在本申请的具体实施方式中，所述环形摩擦面119、119'、119”、119”'为环形的竖直面。需要说明的是，在本申请的其他实施方式中，所述环形摩擦面119、119'、119”、119”' 也可以为锥面等其他形状。无论如何，所述环形摩擦面119、119'、119”、119”'需要在第一连接件11、11'、11”、11”'与第二连接件12、12'、12”、12”'相互组装的组装方向上延伸一定的距离，即所述环形摩擦面119、119'、119”、119”'不是第一连接件11、11'、11”、11”'与第二连接件12、12'、12”、12”'相互贴合的贴合面(该贴合面在本申请图示的实施方式中为水平面)。
在上述所有实施方式中，密封件13、13'、13”、13”'被压缩变形产生的高度差范围在0.15至0.45倍的原始高度之间。如此设置，可在密封件13、13'、13”、13”'达成最佳密封效果时，保证第二连接件12、12'、12”、12”'与第一连接件11、11'、11”、11”'不会相互卡死。

以上所述仅是本专利申请的较佳实施例而已，并非对本专利申请做任何形式上的限制，虽然本专利申请已以较佳实施例揭露如上，然而并非用以限定本专利申请，任何熟悉本专业的技术人员，在不脱离本专利申请技术方案的范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的 等效实施例，但凡是未脱离本专利申请技术方案的内容，依据本专利申请的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本专利申请技术方案的范围内。
