下面结合附图详细描述本发明的热管理模块。
图1示出现有技术的一种热管理模块的旋转阀的透视图。如图1所示，现有技术的热管理模块的旋转阀V具有多个通道，例如三个通道。通道具有开口，例如开口1、开口2和开口3。开口1、开口2和开口3中的每个开口相对于旋转阀V的相应横截面是对称的。换言之，开口1、开口2和开口3中的每个开口在旋转阀V的轴向方向上是左右对称的。开口1和开口2相继布置在旋转阀的周向方向上，而开口3布置在开口1和开口2在旋转阀的轴向方向上的一侧上。
图1的上部分示出了开口1和开口2的缩小的平面展开图。需要说明的是，为了图示方便，图1的上部分的平面展开图相对于图1的下部分中的开口1和开口2旋转了90度。在平面展开图中，开口1形成为大致图钉的形状，具体地具有基部部分和从基部部分的直线边缘突出的尖端部分，该基部部分具有将圆切除掉较小部分而形成的形状。开口2形成为大致楔形的形状，具体地具有矩形的基部部分和从基部部分的一边突出的角形部分。
现有技术的热管理模块的旋转阀V的开口1、开口2和开口3都具有平行于旋转阀的轴向方向的分模线。
图2示出本发明的热管理模块的旋转阀的开口与现有技术的对应开口重叠情况下的对照平面展开图。如图2所示，与现有技术的开口1和开口2相比，本发明的开口1′和开口2′的各自一部分沿着旋转阀的轴向方向朝向一侧偏置，具体地，开口1′的尖端部分沿着旋转阀的轴向方向朝向一侧偏置，而开口2′的角形部分沿着旋转阀的轴向方向朝向所述一侧偏置。并且，开口2′的大致矩形端部沿着旋转阀的轴向方向朝向开口2′的角形部分偏置所朝向的所述一侧相反的另一侧偏置从而变形为锐角尖端部分。即，开口1′的尖端部分仅在旋转阀的轴向方向朝向一侧偏置，而开口2′的大致矩形端部和角形部分朝向在旋转阀的轴向方向上的相反的两侧偏置。由此，开口1′和开口2′在旋转阀的轴向方向上是非对称的。
图3示出本发明的热管理模块的旋转阀的开口与现有技术的对应开口分开情况下的对照平面展开图。如图3所示，与现有技术的旋转阀的对称的开口相比，本发明的开口1′是非对称的并且具有相对于旋转阀的轴向方向倾斜的分模线4。类似地，开口2′也是非对称的并且具有相对于旋转阀的轴向方向倾斜的分模线。
图4示出本发明的热管理模块的旋转阀的开口与现有技术的对应开口重叠情况下的对照平面展开图。如图4所示，在平面展开图中，现有技术的开口3形成为大致跑道的形状，具体地具有矩形的基部部分和两个大致半圆形端部部分，所述两个大致半圆形端部部分在垂直于旋转阀V的轴向方向的方向上从所述开口3的基部部分的边缘朝向两侧突出。与现有技术的开口3的半圆形端部部分相比，本发明的开口3′的端部部分变成尖角形状的。具体地，开口3′的一个端部部分朝向旋转阀的轴向方向上的一侧偏置，而开口3′的另一个端部部分朝向旋转阀的轴向方向上的另一侧偏置。由此，开口3′在旋转阀的轴向方向上是非对称的。
图5示出本发明的热管理模块的旋转阀的开口与现有技术的对应开口分开情况下的对照平面展开图。如图5所示，与现有技术的旋转阀的对称的开口3相比，本发明的开口3′是非对称的并且具有相对于旋转阀的轴向方向倾斜的分模线5。
此外，旋转阀可以在其径向方向上的相反侧上同时具有非对称的开口。即，旋转阀可以在其径向方向上的相反侧上具有多个非对称的开口。这种情况下，旋转阀中的非对称的开口在旋转阀的相反侧上定向在相反的方向中。由此，用于相反的通道的主密封件将在相反方向上旋转，以补偿在旋转阀处由主密封件的旋转导致的轴向反作用力。
图6示出了本发明的热管理模块的密封组件的截面图。如图6所示，密封组件安装在热管理模块的壳体6的开口中。经过该开口，热管理模块的旋转阀与外部冷却管道相连通。密封组件包括主密封件7、次密封件8和密封件支架9。密封组件的主密封件7可以直接接触旋转阀，而密封件支架9通过弹簧(未示出)固定。具体地，弹簧的一端固定在壳体6上，而另一端抵靠在密封件支架9上。利用该弹簧，保证了主密封件7以足够的张紧力压靠在旋转阀上。
密封件支架9包括空心的柱形部92和与柱形部92的轴向端部连接到一起的凸缘91。密封件支架9的柱形部92与热管理模块的壳体6之间存在空间。主密封件7和次密封件8是大致环形的，且都安装在密封件支架9和热管理模块的壳体6之间的空间中。主密封件7接触旋转阀V用于对旋转阀V进行密封，而次密封件8一方面接触壳体6的内壁而另一方面接触密封件支架9的柱形部92的外壁，用于在热管理模块的壳体6和密封件支架9之间进行密封。次密封件8在旋转阀V的径向方向上布置在主密封件7的外侧并抵靠主密封件7。并且，密封件支架9的凸缘91在旋转阀V的径向方向上布置在次密封件8的外侧并抵靠次密封件8。
密封组件的主密封件7的径向内侧与密封件支架9的柱形部92隔开，从而在两者之间形成间隙A。密封组件的主密封件7的径向外侧与热管理模块的壳体6隔开，从而在两者之间形成间隙B。由于主密封件7与密封件支架9和热管理模块的壳体6两者都隔开，所以主密封件7松配合在密封件支架9上且松配合在热管理模块的壳体6中。由此，在旋转阀V旋转的同时主密封件7可以旋转。此外，主密封件7在靠近旋转阀的端部处具有钩部，主密封件7通过该钩部钩在密封件支架9的柱形部92的端部上，从而限制了主密封件7在柱形部92的轴向方向上的移动。
通过调整主密封件7的外径和内径，可以在主密封件7的径向方向上产生所需间隙。主密封件7和次密封件8之间的密封功能仅仅在密封组件的轴向方向上实施。
图7示出了本发明的热管理模块的密封组件与旋转阀相配合的视图。需要说明的是，图7中仅仅示出了旋转阀V的包括开口的一部分，而省略了其他部分。如图7所示，密封组件的主密封件7接触并压靠旋转阀的开口的周边部分，从而对旋转阀进行密封。在旋转阀运行的过程中，主密封件7的内孔与旋转阀的开口的重叠部分是可以逐渐改变的，由此流过旋转阀的开口的流量是可以改变的。当主密封件7的内孔与旋转阀的开口正好完全重叠时，流过旋转阀的开口的流量最大。
此外，通过调节密封组件的轴向预紧力例如改变弹簧的刚度，可以控制主密封件7旋转。由于均匀的密封件磨损和旋转阀处的较小的摩擦扭矩，所需的轴向预紧力是小的。
本发明的热管理模块的旋转阀的开口的分模线相对于旋转阀的轴向方向是倾斜的，即既不平行于也不垂直于旋转阀的轴向方向，由此将产生使得主密封件旋转的力/扭矩，并且防止了移位扭矩峰值。
另外，旋转阀的通道的开口的内径优选小于主密封件7的内径，由此进一步防止了移位扭矩峰值。
可以预期的是，在不脱离所附权利要求限定的本发明的精神和范围的情况下，可以进行本发明的各种变形和修改。
