Description

阀组件、热交换组件和变速箱油温度调节系统
本申请要求2017年09月27日提交中国专利局、申请号为201710889129.6、发明名称为“阀组件、热交换装置和变速箱油温度调节系统”的发明专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及流体控制领域，具体涉及一种阀组件、热交换组件和变速箱油温度调节系统。
背景技术
汽车在行驶过程中各部件之间需要及时以润滑油润滑来保证汽车的正常运行。如果润滑油润滑性能不够好会影响汽车使用寿命。而润滑油的润滑性能和其自身的温度有很大的关联，当润滑油温度过高或者过低时，润滑油的润滑性能会受到影响。
现有的变速箱油主要通过调温阀和外部冷却装置组成的冷却流路来实现温度调节功能。一般的热管理系统，采用换热器来进行冷却，利用冷却水或者冷媒对热油进行冷却，以达到变速箱油保持在一定的工作温度范围内。在调温阀中通过阀芯来控制润滑油或者冷却液的流动路径，以达到切换流体流动路径的目的。
但是，由于阀芯是根据热敏物质感受流体的温度热胀冷缩，从热敏物质感受温度到热胀冷缩再到给予弹簧作用力，需要一定的响应时间，即阀芯的响应时间较慢，会使润滑油的温度产生一定的滞后性，会影响到变速器的性能，甚至损坏变速器。并且，阀芯体积较大，需要与弹簧配合才能实现流动路径的切换。

具体实施方式
下面结合附图和具体实施方式，对技术方案进行具体说明，本说明书所述的顶部、底部、左侧、右侧等方位名词皆按照附图相应方位关系来阐述的。
如图1和图2所示，阀组件包括中空的主阀体1和安装在主阀体1内的阀芯6。主阀体1的两端开口，在主阀体1内部的两端部分别固定安装有上阀套2和下阀套3。在主阀体1内还设置有第一弹簧4和第二弹簧5，第一弹簧4的一端与下阀套3相抵接，第一弹簧4的另一端与阀芯6的一端相抵接，第二弹簧5的一端与阀芯6的另一端相抵接，第二弹簧5的另一端与上阀套2相抵接。第一弹簧4和第二弹簧5处于压缩状态，从而阀芯6固定于主阀体1内。这里应当说明，第二弹簧5是由记忆合金材料制成的弹簧，其具有当温度高于特定温度时产生弹性性能、且当温度低于特定温度时其弹性性能失效的特性。在正常状态下，第二弹簧5失去弹性特性被完全压缩。
如图4所示，主阀体1的两端分别设置有第一开口11和第二开口12，其中第一开口11的内径大于第二开口12的内径，第二开口12的内壁设置有内螺纹。主阀体1内还设置有容纳腔15，容纳腔15位于第一开口11和第二开口12之间，容纳腔15的内径小于第一开口11的内径，在第一开口11和容纳腔15之间形成有台阶部，第二开口12的内径小于容纳腔15的内径，在容纳腔15与第二开口12之间形成有台阶部。
容纳腔15所对应的主阀体1的侧壁开设有第一缺口13，第一缺口13位于下阀套3的上方，具体在本实施例中，第一缺口13靠近第一开口11和容纳腔15之间形成有台阶部。为了使第一缺口13的开口面积较大，同时又使主阀体1较为稳固，第一缺口13包括第一子缺口131和第二子缺口132，同时在第一子缺口131和第二子缺口132之间设置有环装连接部14，其中环装连接部14可以是主阀体1的侧壁的一部分。如果不设置环装连接部14，这样，当第一缺口13较大时，第一缺口13所对应部分的主阀体13 的侧壁为连接柱133，这样主阀体1的稳固性较低，而通过设置环装连接部14，可以较好提高主阀体1的稳固性。
如图2所示，上阀套2通过上阀套2包括外径较大的支撑部21和相对支撑部21外径较小的主体部212，所述主体部212的外壁与所述容纳腔的内壁之间保持一定的距离以形成流体通道。第二弹簧5的一部分套设于主体部外，并且第二弹簧5的一端与主体部的外壁相抵接。主体部212的侧壁还设置有第二阀口211和第二缺口22，其中第二缺口22位于第二阀口211的下方。
阀芯6包括相对靠近上阀套2的第一端61和相对远离上阀套2的第二端62，其中第一端61伸入主体部212内，通过第一端61相对远离或者抵接第二阀口211来打开或者关闭第二阀口211。当第二阀口211打开时，通过第一缺口13流入的流体可以通过第二缺口22和第二阀口211流出。
如图2所示，上阀套2的支撑部21与在第一开口11和容纳腔15之间形成的台阶部相接触，上阀套2可以通过第一卡扣91固定，支撑部与第一开口的内壁之间间隙配合。这里应当指出，上阀套2也可以通过其他方式(例如铆压、螺纹连接等)固定。为了提高密封性能，还可以在支撑部21与容纳腔15的内壁之间设置密封圈。
如图2所示，下阀套3的一部分位于容纳腔15，下阀套3的另一部分位于第二开口12并且与第二开口12的内壁之间螺纹连接。
下阀套3包括阀座部34、弹簧支撑座33、配合部35和贯穿下阀套3的贯通孔32，阀座部34中设置有一贯穿阀座部的第一阀口31，所述第一阀口31可以为贯通孔32的一部分，相对于第一缺口，第一阀口相对远离第一开口。配合部35设置有外螺纹，可以与主阀体1的第二开口12的内螺纹相配合，从而使下阀套3固定安装。
在本实施例中，为了便于下阀套3的安装，还设置有凹陷于弹簧支撑部33的凹部37，凹部37可以是多边形结构，也可以是多个下凹结构，这里不做限制。
在本实施例中，在弹簧支撑部33和阀座部34之间还设置有第三缺口36。第三缺口36与配合部35相对应的贯通孔32部分相连通，即穿过第三缺口36的流体可以通过贯通孔32的下端口流出下阀套3。
如图2所示，下阀套3的配合部35与主阀体1的第二开口12的内壁之间通过螺纹连接固定。第一弹簧4的一端与阀芯6相抵接，另一端与弹簧支撑座33相抵接。
阀座部34的外径大于下阀套3的其它部分的外径，并且阀座部34的外径小于容纳腔15的内径，阀座部34的外壁与容纳腔15所对应的内壁之间形成有供流体流动的通道。在容纳腔15内还设置有泄压环7和第三弹簧8，所述泄压环设置有通孔，通过所述通孔，所述泄压环套设于所述下阀套，所述通孔的内径小于所述阀座部的外径，使得泄压环7可以与阀座部34相抵接，泄压环7与容纳腔15所对应的内壁之间滑动配合。第三弹簧8的一端与泄压环7相抵接，另一端与容纳腔15和第二开口12之间形成的台阶部相抵接，并且第三弹簧8处于压缩状态。在正常状态下，泄压环7在第三弹簧8的作用下与阀座部34相抵接，阀座部34的外壁与容纳腔15所对应的内壁之间形成的供流体流动的通道被泄压环7所关闭，阀座部34的外壁与容纳腔15所对应的内壁之间形成的供流体流动的通道无法与第三缺口36相连通。当流体作用在泄压环7上端面的作用力大于第三弹簧8的初始弹性形变力时，泄压环7向下运动压缩第三弹簧8，当泄压环7向下运动到与第三缺口36相交或者位于第三缺口36下方时，阀座部34的外壁与容纳腔15所对应的内壁之间形成的供流体流动的通道通过第三缺口36和第二开口12连通。
如图2和图3所示，阀芯6包括第一端62和第二端61，第一端62与第一阀口31相对应，通过第一端62可以打开关闭第一阀口31，第二端61与第二阀口211相对应，通过第二端61可以打开关闭第二阀口211。并且第二端61的至少一部分伸入主体部212内，这样能够定位阀芯6，防止阀芯6产生移位，提高阀芯6的稳定性。
本实施例的阀组件至少包括两种状态：1、第一阀口打开，第二阀口关闭，2、第一阀口关闭，第二阀口打开。当从第一缺口13流入的流体温度较低且低于第二弹簧5产生弹性特性的温度时，阀芯6的第一端62在第一弹簧4的回复力的作用下远离第一阀口31，第二端61与第二阀口211相抵接，此时第一阀口31打开，第二阀口211关闭，流体从第一缺口13流入后，能够依次通过第一阀口31、贯通孔32和第二开口12流出；当从第 一缺口13流入的流体温度大于第二弹簧5产生弹性特性的温度时，第二弹簧5产生弹性性能，此时第二弹簧5的弹力大于第一弹簧4的弹力，阀芯6在第二弹簧5的弹力的作用下向下动作，第一端62向下运动压缩第一弹簧4，直至关闭第一阀口31，此时第一阀口31关闭，第二阀口211打开，流体从第一缺口13流入后，流体能够依次通过第二缺口22、第二阀口211和第一开口11流出。
通过设置由记忆合金制成的第二弹簧，可以无需再设置热动元件，此时阀芯结构简单，体积也较小，并且相对于热动元件，由记忆合金制成的第二弹簧的响应速度较快，在温度低于特定温度时，第二弹簧能够迅速失去弹性特性而被第一弹簧所压缩，而当温度高于特定温度时，第二弹簧的弹性特性被迅速启动，能够及时关闭第二阀口。并且，即便是流体温度高于特定温度很多时，第二弹簧也不会像热动元件一样过度膨胀而损坏。
在本实施例中还包括泄压状态，当第一阀口31关闭时，如果流体流出阀组件后的其它外部装置或者管路阻塞，流体无法从第一开口11流出阀组件时，从而使流体的压力大于第三弹簧的初始弹性形变力时，泄压环7向下运动，泄压环7向下运动压缩第三弹簧8，当泄压环7向下运动到与第三缺口36相交或者位于第三缺口36下方时，流体依次通过阀座部34的外壁与容纳腔15所对应的内壁之间形成有供流体流动的通道、第三缺口36、贯通孔32和第二开口12流出。
这里应当指出，当无需泄压功能时，此时下阀套3可以与主阀体1为一个整体，即下阀套3中的阀座部34和弹簧支撑座33为主阀体1的一部分，例如可以第二开口12与容纳腔15之间的台阶部所对应的第二开口12的端部可以作为第一阀口，再在第二开口12内设置一弹簧支撑座33。
图6至图8示出了安装有上述阀组件的热交换组件，如图所示，热交换组件包括换热芯体10、与换热芯体相固定的安装板101、转接座、第一接口1041、第二接口1042、第三接口1011和第四接口1012。换热芯体10包括端板102、以及相互隔离的第一流道和第二流道，流动在第一流道中的流体和流动在第二流道中的流体可以进行热交换。其中第一流道与第一接口1041和第二接口1042相连通，第二流道与第三接口1011和第四接口1012相连通。
其中第一接口1041和第二接口1042通过接管的形式与外部系统相连通。第三接口1011和第四接口1012形成于安装板101,第三接口1011和第四接口1012贯穿安装板101，这样可以使安装板直接固定于变速箱，安装方便，外漏风险较小。为了进一步提高密封性能，防止外漏风险，在安装板101的第三接口1011和第四接口1012的外周侧还分别设置有密封圈1013和密封圈1014。
第二流道包括第一通道1051和第二通道1052，第一通道1051的一端与第三接口1011相连通，第一通道1051的另一端受到端板102的阻挡，第二通道1052的一端与第四接口1012相连通，第二通道1052的另一端与转接座相连通。
转接座包括第一转接座1031和第二转接座1032，第一转接座1031包括容纳腔1034、以及与容纳腔1034相连通的第五接口1033。第二转接座1032包括座体1036，座体1036中形成有贯穿座体1036的腔，贯穿座体1036的腔所对应的座体1036的内壁形成有台阶1035。
第二转接座1032与端板102相固定，例如通过焊接、螺纹连接等方式相密封固定。并且，贯穿座体1036的腔与第二通道1052相对应。第一转接座1031与第二转接座1032通过螺纹连接等方式相固定，并且贯穿座体1036的腔与容纳腔1034相对应，第五接口1033可以通过容纳腔1034与贯穿座体1036的腔的至少一部分相连通。所述第一转接座和第二转接座通过螺钉固定连接，为了提高密封性能，在第一转接座1031和第二转接座1032的密封面之间还可以设置密封圈。
阀组件设置于第二通道1052，阀组件的至少一部分位于第二通道1052，在本实施例中，至少一部分位于转接座内。阀组件通过在第二转接座1032设置卡环1037固定，从而限制阀组件的轴向位移。
图7和图8示出一种具有上述热交换组件的变速箱油温度调节系统，变速箱油温度调节系统包括变速箱、热交换组件、油冷器和发动机水箱(图中未示出)，其中热交换组件的第一接口和第二接口通过管路与发动机水箱相连通，第三接口和第四接口直接或者通过管路与变速箱的进出口相连通。油冷器的其中一个流道通过管路与热交换组件的第五接口和变速箱的进口相连通，油冷器的另一个流道可以与制冷系统(图中未示出)相连通。
当从变速箱出口出来的冷却油进入换热芯体进行热交换后的温度处于正常状态时，通过第一缺口进入阀组件的冷却油，由于阀芯在第一弹簧的回复力作用下第一阀口31处于开启状态，而第二阀口211处于关闭状态，冷却油可以穿过第一阀口31后通过第四接口和变速箱的进口流回变速箱，这样完成一次循环。
当从变速箱出口出来的冷却油进入换热芯体进行热交换后的温度超过正常温度时，冷却油通过第一缺口流入阀组件，此时阀芯受热膨胀，阀芯向下运动关闭第一阀口31，此时，第一阀口31处于关闭状态，第二阀口211处于打开状态，冷却油可以穿过第二阀口211后通过第五接口流向油冷器，高温冷却油在油冷器中经过热交换降温至正常温度状态后通过变速箱进口流回变速箱，这样完成一次循环。
进一步的，当冷却油温度较高，而油冷器有发生堵塞时，此时，虽然第一阀口31处于关闭状态，但高温冷却油可以利用阀组件的泄压功能，使冷却油能够通过阀座部34的外壁与容纳腔15所对应的内壁之间形成有供流体流动的通道、第四接口和变速箱的进口流回变速箱，防止变速箱缺油损坏。
以上所述，仅是本发明的具体实施例而已，并非对本发明作任何形式上的限制，并且文中所出现的上下左右等方位性词汇均以附图进行描述，并非对其方位进行限制。虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明。任何熟悉本领域的技术人员，在不脱离本发明技术方案范围情况下，都可利用上述揭示技术内容对本发明技术方案做出许多可能的变动和修饰，或修改为等同变化的等效实施例。因此，凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所做的任何简单修改、等同变化及修饰，均仍属于本发明技术方案保护的范围内。
