在本实施例中，流体控制组件100应用于热管理系统包括但不限于三种工作模式：
第一工作模式：第一阀部件21、第三阀部件23、第四阀部件24、第七阀部件27关闭，第二阀部件22、第五阀部件25、第六阀部件26、第八阀部件28打开，此时第二阀部件22直通连通第一接口341和第七接口347，第五阀部件25节流连通第四接口344和第五接口345，第六阀部件26节流连通第四接口344和第六接口346，第八阀部件28直通连通第八接口348和第九接口349。
热管理系统处于第一工作模式时：压缩机201出口侧的高温高压气相工作流体(如制冷剂)从第一接口341流入第一流道331，在第一阀部件21关闭的情况下，位于第一流道331的高温工作流体通过第二阀部件22直通流入第二流道332，在第三阀部件23和第七阀部件27关闭的情况下，位于第二流道332的高温工作流体从第七接口347流出，流向第三换热器205，经第三换热器205冷却散热后变为较高温的工作流体流向气液分离器202，经气液分离器202中间再次换热冷却后，从第五接口345流入，经第五阀部件25节流后变为低温低压气液两相工作流体：其中一部分从第四接口344流向第二换热器204，经第二换热器204蒸发吸热后变为较低温工作流体从第九接口349流入第八流道338，在第四阀部件24和第七阀部件27关闭的情况下，位于第八流道338的较低温工作流体通过第八阀部件28直通流向第七流道337，并通过与第七流道337连通的第八接口348流出；经第五阀部件25节流后的另外部分工作流体(低温低压气液两相)流入第 五流道335，经第六阀部件26再次节流后从第六接口346流向第四换热器206的第一通道，与第四换热器206的第二通道内的工作流体(如冷却液)热交换蒸发吸热后变为较低温工作流体，与从第八接口348流出的较低温工作流体汇合后共同流向气液分离器202，经气液分离器202气液分离后气相工作流体回流至压缩机201的进口进行再循环。
第二工作模式：第二阀部件22、第三阀部件23、第八阀部件28关闭，第一阀部件21、第四阀部件24、第五阀部件25、第六阀部件26、第七阀部件27打开，此时第一阀部件21直通连通第一接口341和第二接口342，第四阀部件24直通连通第三接口343和第九接口349，第五阀部件25节流连通第四接口344和第五接口345，第六阀部件26节流连通第四接口344和第六接口346，第七阀部件27直通连通第七接口347和第八接口348。
热管理系统处于第二工作模式时：压缩机201出口侧的高温高压气相工作流体从第一接口341流入第一流道331，在第二阀部件22关闭的情况下，从第一接口341流入的高温高压气相工作流体直接通过第一阀部件21直通流向第二接口342，从第二接口342流向第一换热器203，经第一换热器203冷却散热后变为较高温的工作流体流向第三接口343，并流向第三流道333，在第三阀部件23关闭的情况下，从第三接口343流入的工作流体通过第四阀部件24直通流向第四流道334，在第八阀部件28关闭的情况下，位于第四流道334的工作流体从第九接口349流向第二换热器204，经第二换热器204再次冷却散热后从第四接口344流入，并流向第五流道335，从第四接口344流入的一部分工作流体通过第五阀部件25节流后变为低温低压气液两相工作流体从第五接口345流出，流向气液分离器202，经气液分离器202中间换热吸热后流向第三换热器205，经第三换热器205蒸发吸热后变为较低温的工作流体从第七接口347流入第二流道332，在第二阀部件22和第三阀部件23关闭的情况下，位于第二流道的332工作流体通过流道连接板33的第一通孔331流向第六流道336，并经第七阀部件27直通流向第七流道337，在第八阀部件28关闭的情况下，位于第七流道337的工作流体从第八接口348流出；从第四接口344流入的另外部分工作流体流入第五流道335，经第六阀部件26节流后变为低温低压气液两相工作流体从第六接口346流出，流向第四换热器206的第一通道，与 第四换热器206的第二通道内的工作流体(如冷却液)热交换蒸发吸热后变为较低温工作流体，与从第八接口348流出的较低温工作流体汇合后共同流向气液分离器202，经气液分离器202气液分离后气相工作流体回流至压缩机201的进口进行再循环。需要指出的是：在第二工作模式中，为适应不同的需求，如工作流体过冷度的需要，其中第四阀部件2还可以节流连通第三接口343和第九接口349。
第三工作模式：第二阀部件22、第四阀部件24、第七阀部件27、第八阀部件28关闭，第一阀部件21、第三阀部件23、第五阀部件25、第六阀部件26打开，此时第一阀部件21直通连通第一接口331和第二接口342，第三阀部件23直通连通第三接口343和第七接口347，第五阀部件25节流连通第五接口345和第五流道335，第六阀部件26节流连通第五流道335和第六接口346，即第五阀部件25和第六阀部件26共同节流连通第五接口345和第六接口346。
热管理系统处于第三工作模式时：从压缩机201出口侧的高温高压气相工作流体从第一接口341流入第一流道331，在第二阀部件22关闭的情况下，工作流体通过第一阀部件21直通流向第二接口342，经第一换热器203冷却散热后变为较高温的工作流体流向第三接口343，在第四阀部件24关闭的情况下，从第三接口343流入的工作流体流向第三流道333，经第三阀部件23直通流入第二流道332，在第二阀部件22和第七阀部件27关闭的情况下，位于第二流道332的较高温工作流体通过第七接口347流向第三换热器205，经第三换热器205再次冷却散热后流向气液分离器202，经气液分离器202中间换热进一步冷却后从第五接口345流入，经第五阀部件25节流后变为低温低压气液两相工作流体，在第四阀部件24和第八阀部件28关闭的情况向，节流后的工作流体无法从第四接口344通过第二换热器205实现流通路径，即经第五阀部件25节流后工作流体流入第五流道335，经第六阀部件26再次节流后从第六接口346流向第四换热器206的第一通道，与第四换热器206的第二通道内的工作流体(如冷却液)热交换蒸发吸热后变为较低温工作流体流向气液分离器202，经气液分离器202气液分离后气相工作流体回流至压缩机201的进口进行再循环。
根据上述热管理系统的工作模式可知，第五阀部件25和第六阀部件26作为节流阀部件应用，主要用于对从压缩机201出来的高温高压工作流体或经冷凝后的较高温高压工作流体进行节流处理后变为低温低压工作流体，而第一阀部件21、第二阀部件22、第三阀部件23、第四阀部件24主要为应用于节流前对高温高压或较高温高压工作流体导通的阀部件，定义该部分阀部件为高压侧阀部件或节流前阀部件，如在本实施例中第一阀部件21至第四阀部件21为高压侧阀部件或节流前阀部件，定义与第一阀部件21至第四阀部件24建立连通关系的流道为高压侧流道或节流前流道，也即第一部分流道，高压侧流道(或者说节流前流道)内的工作介质多为高温或较高温的高压工作流体，而第七阀部件27和第八阀部件28则主要为应用于节流后对低温低压或较低温低压工作流体导通的阀部件，定义该部分阀部件为低压侧阀部件或节流后阀部件，如在本实施例中第七阀部件27和第八阀部件28为低压侧阀部件或节流后阀部件，定义与第七阀部件28和第八阀部件28建立连通关系的流道为低压侧流道或节流后流道，也即第二部分流道，低压侧流道(或者说节流后流道)内的工作介质多为低温或较低温的低压工作流体。定义高压侧和低压侧以节流前后进行划分。
为减少节流前流道内的高温或较高温工作流体与节流后流道内的低温或较低温工作流体之间的有害传热，设置第一阀部件21至第四阀部件24位于第一流道板31，这样形成与第一阀部件21至第四阀部件24建立连通关系的节流前流道的至少部分位于第一流道板31，具体地，在本实施例中，形成节流前流道(第一流道331、第二流道332、第三流道333、第四流道334)的槽腔位于第一流道板31，第一流道板31与流道连接板33配合形成节流前流道。设置第七阀部件27和第八阀部件28位于第二流道板32，这样形成与第七阀部件27和第八阀部件28建立连通关系的节流后流道的至少部分位于第二流道板32，具体地，在本实施例中，形成节流后流道(第五流道335、第六流道336、第七流道337、第八流道338)的槽腔位于第二流道板32，第二流道板32与流道连接板33配合形成节流后流道。在本实施例中，为使流体控制组件结构紧凑，在本实施例中，第五阀部件25和第六阀部件26同样设置于第二流道板。需要理解的是，上述仅为一个实施例进行说明，不失一般性地，可以设置节流前阀部件位于第一流道板31， 与节流前阀部件建立连通关系的节流前流道的至少部分位于第一流道板31，设置节流后阀部件位于第二流道板32，与节流后阀部件建立连通关系的节流后流道的至少部分位于第二流道板32，第一流道板31与第二流道板32不直接接触。
另外，如在本实施例中，沿垂直于第一流道板31的第一壁面310的方向，或者说沿第一流道板31的厚度方向，形成节流前流道的槽腔自第一壁面310向内凹陷形成；沿垂直于第二流道板32的第二壁面320的方向，或者说沿第二流道板32的厚度方向，形成节流后流道的槽腔自第二壁面320向内凹陷形成，第一流道板31与流道连接板33配合形成节流前流道，第二流道板32与流道连接板33配合形成节流后流道，并沿流道连接板33的厚度方向，节流前流道和节流后流道分别位于流道连接板33的两侧，这样将流道以层的方式形成，并进行分层设置，一方便有利于便于将流道做成流线型，减小工作流体的流阻，另一方面有利于延长各个流道的流通路径的长度，减少了流道内工作流体温度因流道流通路径过短而导致过度集中，有利于减少各流道间工作流体的有害传热。进一步地，通过在流道连接板33上设置贯穿的通孔，将分层的节流前流道和节流后流道通过但不限于通孔实现连通，如在本实施例中，通过第一通孔3301将第二流道332的第二子流道3322和第六流道336连通，较好的解决了如前文中所说的第二子流道3322因受布局空间限制导致流通路径长度不长的情况，即通过通孔实现了在空间上延长连接两个阀部件之间的流道的流通路径长度，减少了工作流体温度的集中，有利于减少各流道间工作流体的有害传热。
