结合参照图4和图6，流道板202设置有凸起202e和凹槽202b，该凸起202e朝着背离底板201的方向凸伸，凹槽202b与凸起相对，凹槽202b位于流道板202面向底板201的一侧，冷却组件20包括有第二流体通道202a，第二流体通道202a位于流道板202形成凹槽202b的壁部与底板201之间；流道板202包括主体部202f，凹槽202b连续延伸设置，主体部202f与底板201密封设置，凹槽202b包括第一末端部202c和第二末端部202d，第一末端部202c的位置与第一接口20a相对，第二末端部202d的位置与第二接口20b相对；此处，凹槽的第一末端部202c、第二末端部202d是指凹槽延伸的起始端和终端。该第二流体通道202a用于制冷剂或其他制冷介质(例如CO2)的流通，为了简化描述，以下实施方式均以制冷剂进行相关描述。第二流体通道202a应尽量布满整个流道板202的板面，并尽量减小流阻，可在此需求下对第二流体通道202a的分布进行优化设计。如此，流体自第一接口20a进入第二流体通道202a，流体在底板201与流道板202之间吸收外部热量，由于流道板202和底板201相对厚度较小，平板部与 电池模块40的至少部分接触设置或通过导热元件接触，使得电池模块的热量可迅速经底板201传递给流体，电池冷却效率较高。
底板201、流道板202的厚度一般为0.8-2.5mm，如此，与平板部接触设置的电池模块可更为快速将热量经平板部传递给冷却组件内的流体，实现高效地换热。
请继续参考7-10，图7为图3所示冷却集成组件中接块10的结构示意图；图8为图7中接块10的剖视图。
结合图3和图6，冷却组件20具有第一接口20a、第二接口20b，制冷剂从第一接口20a进入第二流体通道202a内，循环后再从第二接口20b流出。与冷却组件20固定的接块10则具有接块第一端口101、接块第二端口102、接块第三端口103、接块第四端口104，以及用于安装阀芯组件30中阀芯部件的安装孔105。
如图2所示，接块10可以安装在冷却组件20的底板201表面，与底板201表面几乎贴合，这里定义接块10贴合底板201表面的一面为内端面，即朝向冷却组件20底板201的一面为内端面。接块第三端口103和接块第二端口102即位于接块10的内端面，接块10和冷却组件20可以直接焊接固定形成一体，并要求焊接固定后，冷却组件20的第一接口20a和接块第二端口102导通，第二接口20b和接块第三端口103导通，并且接块第一端口101和接块第四端口104位于接块10的同一端面，该实施方式中，接块第一端口101和接块第四端口104位于接块10的外端面，与内端面相对。
本文中，所述的端面意指为接块的外部轮廓，并不局限为一个平面；例如，本文所述的接块第一端口101和接块第四端口104位于接块10的同 一端面是指接块第一端口101与接块第四端口104位于接块10的外部轮廓上的同一侧部，端口可以不设置于在同一个平面上。
当然，在接块各面为平面结构时，此时的位于同一端面才是狭义的端面之意。
另外，安装孔105的孔口设于接块10的侧端面，图7中的接块10大致为一长方体结构(角端位置有圆角，且设有安装孔105的一侧具有更厚的厚度)，安装孔105的孔口设于四个侧端面之一，安装孔105能够连通接块第一端口101和接块第二端口102。
接块第二端口102、接块第三端口103沿长方体结构的接块10的长度方向分布，与第一接口20a、第二接口20b位置对应；相应地，接块第一端口101和接块第四端口104也可沿接块10长度方向分布，如图7所示，安装孔105的孔口靠近接块第一端口101的侧端面，此时接块第一端口101和接块第二端口102之间、接块第三端口103和接块第四端口104之间均形成便于制冷剂流动的通路，分别定义为第一流体通道10c、第三流体通道10d。第一流体通道10c的通道流通面积为零及零以上，且第一流体通道10c的通道流通面积在零与第一流体通道10c的额定流通面积范围内变化。其中第一流体通道10c的额定流通面积是指阀芯组件30在最大开度时第一流体通道10c的流通面积。第一流体通道10c的通道流通面积是指第一流体通道10c内流体流通面积最小的一段的流通面积，例如节流的一段，其中流通面积是该流体通道内径的截面积。
该实施方式中，接块第一端口101和接块第三端口103在安装孔105 轴向上稍微错开，以便分别对接到安装的阀芯部件的进口和出口位置。其余实施方式中，接块第一端口101、接块第四端口104，以及接块第二端口102、接块第三端口103也均采用沿接块10长度方向分布的方式。
这样，当阀芯组件30的阀芯部件安装到安装孔105内后，自接块第一端口101进入的制冷剂可经阀芯部件节流后流向接块第二端口102，然后经第一接口20a进入第二流体通道202a内，参与换热，再由第二接口20b流出，经过接块第三端口103、接块第四端口104流出冷却集成组件，图3中以及下述其他实施方式的对应附图中，均以箭头表示制冷剂的流动路径。本实施方式中，阀芯组件30包括阀针与节流孔，节流孔为所述第一流体通道10c的一部分，阀芯组件形成所述节流孔，阀针与节流孔的壁部之间留有间隙，节流孔的流通面积为零以上；或者阀针伸入节流孔，节流孔的流通面积为零。
作为其他实施方式，冷却集成组件也可以包括阀球与节流孔，节流孔为第一流体通道10c的一部分，阀球封闭节流孔，则节流孔的流通面积为零；阀球与节流孔之间有间隙，则节流孔的流体面积为零以上。
如图7所示，接块10还设有螺纹孔108，以便螺钉或螺栓108a自螺纹孔108拧入以压紧阀芯组件30。
接块10与冷却组件20的固定方式有多种，例如，接块10与冷却组件20可以采用焊接方式固定。底板201与接块10之间可通过设置复合层或者其他焊料实现焊接。参照图46，底板201包括有凸起55、56，凸起55、56朝着接块方向凸伸，接块10的内端面设置有凹槽，该凹槽与凸起55、 56配合设置。具体地，凹槽设置于接块第二端口102周围，如此凸起55与凹槽在接块第二端口102周围形成焊缝，不仅保证接块与冷却组件的焊接强度，而且由于设置了凸起和凹槽，使得接块第二端口102密封，不易产生泄露风险。同理，在接块第三端口103周围也有一圈凹槽，凹槽与凸起56配合设置，保证接块第三端口103与冷却组件的焊接强度。底板201上凸起的设置方式例如可通过对固定后的冷却组件20进行滚压实现。
作为其他实施方式，参照图47，接块10设置有凸起57、58，凸起57位于接块第三端口103周边位置，凸起58位于接块第二端口102周边位置，冷却组件20设置有凹槽，凸起57、58与冷却组件20的凹槽配合设置并焊接固定，如此凸起57、58与冷却组件20焊接相对容易，焊接强度较高，而且也能降低接块第二端口102、接块第三端口103周围的泄露风险。凸起57、58可以单块，或者以凸筋的形式。
参照图44，冷却集成组件包括固定件50，接块10与冷却组件20可以采用固定件50，例如螺栓的方式固定。接块10设置有第一固定孔，冷却组件20设置有第二固定孔，第二固定孔与接块10的第一固定孔相对应，固定件50的其中一个末端51直径大于第一固定孔、第二固定孔的直径，固定件50的大部分伸入固定孔，且固定件与第一固定孔、第二固定孔螺纹配合，固定件的末端51未伸入第一固定孔、第二固定孔，由于该末端51直径较大，固定件的末端51可与冷却组件20的底部相抵，其中冷却组件20的底部是指未设置接块10的侧部。接块10与冷却组件20直接可单独通过螺栓固定，或者接块10与冷却组件20两者之间先通过焊接固定，再采用螺栓固定，即此时的固定件是螺栓。
参照图45，冷却集成组件还包括固定板53和固定件，固定板53包括至少两个侧部，其中一个侧部与接块10相抵靠，另一个侧部与冷却组件20相抵靠，固定板53可以折弯的形式，相当于将冷却组件20和接块10卡设在固定板53的两个侧部之间。固定板53的两个侧部各设置有通孔54，接块10以及冷却组件20也设置有通孔，固定板53通孔与接块10、冷却组件20上设置的通孔对应设置，且固定件插入该等通孔，固定件与该等通孔螺纹配合以实现固定板53、接块10、冷却组件20的固定。固定件例如为螺栓、螺钉等。
作为其他实施方式，固定板也可以为两个，固定板中的一个侧部与接块10相抵靠，另一个固定板的一个侧部与冷却组件20相抵靠，同样，两个固定板和冷却组件20、接块10设有位置对应的通孔，从而通过固定件紧固。
如上设置，可达到如下技术效果：
本方案中的组件，包括阀芯组件30、接块10和冷却组件20，三者固定设置形成一体，冷却组件20的第一接口和接块第二端口102导通，如此冷却集成组件结构简单且紧凑，另外，接块10包括第一流体通道10c，第一流体通道10c的通道流通面积在零与第一流体通道10c的额定流通面积范围内变化，使得流经冷却组件20的流量大小可控，有助于提高换热效率。相比传统的热力膨胀阀，能够进行更为精确的调节，应用至汽车电池的冷却时，可以保证电池工作时的工作温度和环境温度都在最优区间；
而且，接块10与冷却组件20距离非常近，制冷剂几乎在接块10内节流后，即进入冷却组件20内进行换热，减少了连接管路带来的制冷剂气液 分层现象，使得气液混合分布均匀，最接近理论设计，对换热性能的影响较少，从而提高换热效率；
此外，该冷却集成组件，安装更为简单、省时；安装至整车或者其他设备时，仅需安装该组件即可，无需再布置安装支架，也不需要再安装外接管路连接膨胀阀和冷却组件20；
需要强调的是，作为进一步的优化方案，该冷却集成组件最终的出口(接块第四端口104)能够与接块第一端口101处于同一端面，结构非常紧凑，也便于外接管路的连接。而且，整个组件的制冷剂进口、出口可以在连接外接管路时，在连接处安装同一压块(图6示出两个压块安装孔107)，即由同一压块压紧连接位置，从而进一步节省零部件，能够降低成本和产品重量，结构也更为紧凑。
应当知晓，接块10为“一进一出”结构即可，即接块第一端口101和接块第二端口102之间的通路为工作流道。这里在接块10中还另设接块第三端口103和接块第四端口104之间的第二流体通道，其目的是让从冷却组件10流出的制冷剂能够从接块10流出，继而使最终的出口能够与接块第一端口101处于同一端面，这样整个组件的制冷剂进口、出口可以在连接外接管路时，在连接处安装同一压块，即由同一压块压紧连接位置，从而进一步节省零部件，结构也更为紧凑。
再者，冷却集成组件的安装性能也更为可靠，由于阀芯组件与冷却组件之间不再需要连接管路，抗震性会显著提升，阀芯组件和冷却组件20之间的泄漏风险显著降低。
值得注意的是，本实施方式中，接块第一端口101和接块第四端口104 位于接块10的外端面，接块第二端口102和接块第三端口103位于接块10的内端面，且安装孔105位于侧端面，如图8所示，此时接块第一端口101-阀芯部件(安装孔105的位置)-接块第二端口102形成的制冷剂流动路径几乎是贯通接块10呈直线状，接块第四端口104和接块第三端口103之间形成的制冷剂流出的路径也同样是直线状。这种直上直下的流动路径设置，使得制冷剂在接块10中流动时流阻较小、压降低，能够提升换热的效率。
作为其他实施方式，请参考图9-13，图9为本发明所提供冷却集成组件第二实施方式的结构剖视图；图10为图9中去除阀芯组件30后的结构示意图；图11为图10冷却集成组件中接块10的结构示意图；图12为图11的仰视图；图13为图11中接块10的剖视图。
该实施方式接块10结构与实施方式1不同，其他结构大体相同，接块10与冷却组件20的连接方式、导通方式也大体相同，不赘述。
第二实施方式中，安装阀芯部件的安装孔105的孔口与接块第一端口101、接块第四端口104均位于接块10的外端面，与内端面相对，此时的螺纹孔108的孔口设于接块10的侧端面。接块第二端口102和接块第三端口103还是设于内端面，内端面贴合在冷却组件20的底板201，以与第一接口20a、第二接口20b导通。
由于安装孔105的孔口也设于外端面，而从接块第一端口101进入接块10内部的制冷剂需要再流经安装孔105，此时，可在接块10内部设有引流流道10a，以连通接块第一端口101和安装孔105，如图13所示。此 时安装孔105和接块第二端口102可以通过直接贯通接块10内外端面形成。如此设置时，与实施方式1中直上直下的流动路径不同，接块第一端口101-阀芯部件(安装孔105的位置)-接块第二端口102的流动路径具有弯折段，这样整个路径的高度变短，整个接块10所需的厚度得以减小，从而精简接块10结构，如图11、13所示，接块10为薄块状结构，也是大致呈长方体。
由于引流流道10a的设置，接块第一端口101与内端面的距离可以很小(接块第四端口104与内端面距离也可以很小)，而安装孔105则需要一定厚度以满足阀芯组件30中阀芯部件的安装，所以图11中设置接块第一端口101、接块第四端口104处的端面更低于安装孔105位置，在外端面处形成一台阶。
此外，为了在接块10内部设形成连通接块第一端口101和安装孔105的引流流道10a，接块10可具有加工预口106。如图13所示，加工预口106与接块第二端口102、接块第三端口103均处于内端面，从加工预口106处加工形成的倾斜式的引流流道10a，即斜通道，以接块10高度方向为上下方向，引流通道10a具有上端口和下端口，上端口与所述安装孔105连通，下端口与所述接块第一端口101连通。显然，此时的引流流道10a作为第一流体通道10c的一部分。
加工预口106位于内端面，便于加工引流流道10a，并且在接块10焊接到冷却组件20后，贴合于底板201的表面，也可以满足密封性的要求。
图12、13中，加工接块第一端口101时，可以直接沿厚度(图13上下)方向贯通接块10的内外端面形成贯通孔，贯通孔的一端口即为接块第 一端口101，加工预口106可以在另一端口处开设，加工倾斜的引流流道10a时，引流流道10a可以自加工预口106穿过贯通孔后连通至安装孔105，此时的引流流道10a也就通过贯通孔连通接块第一端口101，加工方便，易于实现。
作为其他实施方式，请参考图14-18，图14为本发明所提供冷却集成组件第三实施方式的结构剖视图；图15为图14中去除阀芯组件30后的结构示意图；图16为图15冷却集成组件中接块10的结构示意图；图17为图16的仰视图；图18为图16中接块10的剖视图。
与实施方式2的结构基本相同，实施方式3中的安装孔105的孔口也是与接块第一端口101、接块第四端口104设于接块10的外端面，螺纹孔108设于接块10的侧端面，并且在接块10内部形成连通接块第一端口101和安装孔105的引流流道10a。
只是，实施方式3中接块10的外端面局部呈斜面设置，安装孔105的孔口设于斜面处。该接块10同样呈薄块状，接块10的外端面在安装孔105的位置形成台阶，如图14、15所示，台阶的顶面呈斜面，垂直地贯通斜面至内端面，形成贯通孔，贯通孔的一端口为安装孔105的孔口，另一端口为接块第二端口102。所述安装孔105的孔口当量直径大于所述引流流道10a的通道截面当量直径，如此，安装孔105可作为引流流道10a的加工预口。
此时，贯通斜面的贯通孔呈倾斜设置，即安装孔105也呈倾斜设置，由外向内地朝向接块第一端口101处倾斜，这样不需要再另设引流流道10a 的加工预口，设于斜面的安装孔105即可作为加工预口。从安装孔105处在接块10内部加工出引流流道10a，由此形成的引流流道10a相对于内端面倾斜角度可以减小，或者可以平行于内端面。如图15所示，制冷剂经第一接块10端口和引流流道10a进入安装孔105处时，相较于实施方式2，流动路径更为平缓，流阻和压降也就会更小。
作为其他实施方式，请参考图19-23，图19为本发明所提供冷却集成组件第四实施方式的结构剖视图；图20为图19中去除阀芯组件和线圈组件后的结构示意图；图21为图20冷却组件中接块10的结构示意图；图22为图21的仰视图；图23为图21中接块10的剖视图。
与实施方式2、3的结构基本相同，实施方式4中的安装孔105的孔口也是设于外端面，螺纹孔108设于接块10的侧端面，并且在接块10内部形成连通接块第一端口101和安装孔105的引流流道10a。贯通接块10的内、外端面形成安装孔105和接块第二端口102。实施方式4中，引流流道10a包括连通槽和斜通道，连通槽开设于内端面，连通槽的槽口形成加工预口106，与接块第一端口101相通，如图19所示，加工预口106的截面积大于接块第一端口101的截面积，自上向下，接块第一端口101和加工预口106相接，从而贯通接块10的内、外端面。加工预口106靠近接块第二端口102设置，从连通槽靠近接块第二端口102的位置向内部加工形成引流流道10a的斜通道，引流流道10a的长度相对较短。制冷剂经接块第一端口101-引流流道10a的连通槽-引流流道10a的斜通道-阀芯部件(安装孔105位置)-接块第二端口102。如此设置，加工预口106处的连通槽 也作为制冷剂的流道第二流体通道，加工出的引流流道10a的斜通道长度相对较短，也可以一定程度上减小流阻和压降。
作为其他实施方式，请参考图24-28，图24为本发明所提供冷却集成组件第五实施方式的结构剖视图；图25为图24中去除阀芯组件30后的结构示意图；图26为图25冷却集成组件中接块10的结构示意图；图27为图26的仰视图；图28为图26中接块10的剖视图。
与实施方式2-4的结构基本相同，实施方式5中的安装孔105的孔口也是设于外端面，螺纹孔108设于接块10的侧端面，并且在接块10内部形成连通接块第一端口101和安装孔105的引流流道10a。贯通接块10的内、外端面形成安装孔105和接块第二端口102。
实施方式5中，不设置加工预口，直接以接块第一端口101为加工预口，如图24所示，从接块第一端口101的侧壁，在接块10内部加工出连通接块第一端口101侧壁和安装孔105的引流流道10a，引流流道10a同样是倾斜式的斜通道，以接块10高度方向为上下方向，引流通道10a具有上端口和下端口，上端口与所述接块第一端口101连通，下端口与所述安装孔105连通。此实施方式形成引流流道10a时无需设置加工预口，并且引流流道10a倾斜方向与接块第一端口101、阀芯部件的进口位置相对应，图24中，接块第一端口101位于外端面，处于上方，阀芯部件的进口位置位于安装孔105的底部，处于下方，而引流流道10a也是自上向下倾斜，所以流阻和压降更小。当然，该实施方式中将接块第一端口101作为加工预口，具有相对较高的工艺要求。
实施方式作为其他实施方式，请参考图29-32，图29为本发明所提供冷却集成组件第六实施方式的结构剖视图；图30为图29中去除阀芯组件30后的结构示意图；图31为图30冷却集成组件中接块10的结构示意图；图32为图31中接块10的剖视图。
与实施方式2-5的结构基本相同，实施方式6中的安装孔105的孔口也是设于外端面，螺纹孔108设于接块10的侧端面，并且在接块10内部形成连通接块第一端口101和安装孔105的引流流道10a。贯通接块10的内、外端面形成安装孔105和接块第二端口102。
实施方式6中，设有加工预口106，且加工预口106设于接块10的侧端面，侧端面靠近安装孔105的一侧。如此直接加工出的引流流道10a，贯穿接块10形成安装孔105的壁部，此时的引流流道10a具有第一末端口(图30中右端端口)和第二末端口(图30中左端端口)，第一末端口与接块第一端口101连通，第二末端口位于接块10的侧端面，如图所示，引流流道10a横向地垂直连通于接块第一端口101和安装孔105。此种方式加工工艺简单，易于实现，且相较于实施方式2，制冷剂经引流流道10a时的流阻和压降更小。
由于加工预口106位于接块10的侧端面，加工预口106的位置可以采用堵头10b封堵，实现有效密封，如图30所示。
作为其他实施方式，请参考图33-36，图33为本发明所提供冷却集成组件第七实施方式的结构剖视图；图34为图33中去除阀芯组件30后的结 构示意图；图35为图34冷却集成组件中接块10的结构示意图；图36为图35中接块10的剖视图。
与实施方式6结构基本相同，区别仅在于实施方式7中，加工接块第一端口101时，直接贯通接块10的内、外端面，内端面的贯通口与冷却组件20的底板201配合时密封。相较于实施方式6，制冷剂流经接块第一端口101再进入引流流道10a时，减小流阻和压降，当然，贯通后的内端面位置需要依赖于和底板201的贴合焊接实现密封。
作为其他实施方式，请参考图37-43，图37为本发明所提供冷却集成组件第八实施方式的结构剖视图；图38为图37中去除阀芯组件30后的结构示意图；图39为图37中对应于接块第一端口101、接块第四端口104位置处的横向剖视图；图40为图37冷却集成组件中接块10的结构示意图；图41为图40的透视图；图42为沿图41中接块第一端口101、接块第四端口104轴线所在的面进行剖视的横向剖视图；图43为沿图41中接块第三端口103、接块第二端口102轴向所在的面进行剖视的竖向剖视图。
该实施方式接块10结构与前述实施方式不同，其他结构大体相同，接块10与冷却组件20的连接方式、导通方式也相同，不赘述。
如图41所示，该实施方式中接块第一端口101和接块第四端口104位于接块10的侧端面，接块第二端口102和接块第三端口103还是位于内端面。其中，安装阀芯部件的安装孔105位于接块10的外端面。
图41的透视图以虚线显示出内部的孔道结构，贯通接块10的内外端面形成安装孔105和接块第二端口102，侧面设置的接块第一端口101垂 直连通于安装孔105；从内端面向上延伸的接块第三端口103(并不需要贯通外端面，如图43所示)，侧面设置的接块第四端口104垂直连通于接块第三端口103。
制冷剂从接块第一端口101横向进入接块10内部，然后竖向进入安装孔105经阀芯部件节流后进入冷却组件20，换热后由接块第三端口103竖向流入接块10内部，再横向经过接块第四端口104，流出该冷却集成组件。
应知，当该冷却集成组件安装于汽车后，一般设于汽车底部的电池位置，其内端面、外端面呈上下分布，以便于电池贴合。接块第一端口101、接块第四端口104需要连接外接管路，该实施方式中的接块第一端口101和接块第四端口104位于侧端面，则安装或拆卸外接管路时，操作人员仅需从侧面操作即可，不易受到安装空间限制。
可以理解，实施方式8中，安装孔105也并不限于设于外端面，设于侧端面也是可以的，例如设于图41所示的与接块第一端口101相邻的侧端面。当然，安装孔105设于接块10的外端面时，可以直接贯通内、外端面形成安装孔105的同时也形成接块第二端口102，并且制冷剂流动时流阻和压降也相对更小。
以上各实施方式中，以冷却组件10与电池贴合实现冷却为例进行说明，应知，该冷却集成组件并不限于对车辆的电池进行冷却，对于其他需要进行接触式换热的场合也均可以适用。
以上仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
