更为具体的，流体控制组件10还包括密封件5，密封件5的至少部分位于定位孔2242，定位孔2242为贯穿孔，第一固定件4a、4b的一部分与第二端壁部313相对，第一固定件4a、4b另一部分伸入定位孔2242，且第一固定件4a、4b至少部分与密封件5相抵，且密封件5与安装块2形成定位孔2242的壁部密封设置，例如通过在密封件外周设置密封圈等形式。密封件的设置有助于保证定位孔的密封性，避免流体在此处泄露。
作为其他实施方式，参照图12，所述第二限位部224包括螺纹段2243，所述阀芯部件3包括第二端壁部313，所述第二端壁部313相较所述第一端壁部315而言相对远离所述第一孔道12，沿着所述第一安装孔道21的轴向方向，所述螺纹段2243的端部自与所述第二端壁部313平齐位置朝着相对背离所述第一孔道12的方向延伸；所述流体控制组件10包括第一固定件4c，所述第一固定件4c具有与所述螺纹段2243配合的螺纹部位45，且所述第一固定件4c包括侧壁部42，所述侧壁部42与所述第二端壁部313相抵。

上述实施方式可将单向阀的阀芯部件3集成到安装块2上，减少了连接单向阀与换热芯体1的接头以及附属的零部件，降低了生产成本和安装成本。另外，上述实施方式的安装更加简单、省时、安装更为可靠，降低管路连接的泄露风险，性能上减少额外密封连接处的压力损失，减少流体产生噪音的可能性。另外，阀芯部件3与安装块2固定设置后有助于提高流体控制组件10的强度，且结构更为紧凑。
安装块2包括设置于第一安装孔道21壁部22的第三壁段，第三壁段 相对靠近换热芯体1，第一壁段2211相对靠近第二接口102，第三壁段的内径小于第一壁段2211的内径，且第三壁段的内径大于阀芯部件3的外径，由于安装块2与换热芯体1为焊接固定，为保证阀芯部件3的结构，阀芯部件3的装配在焊接之后进行，如此阀芯部件3可自第二接口102装配，有助于结构紧凑和方便组装。
参照图4、图5、图14、图15，阀芯部件3包括芯体31和活动杆组件32，芯体31在第一安装孔道21内部定位设置，活动杆组件32相对芯体31可作轴向移动，其中轴向定义为沿着第一安装孔道21的延伸方向。所述芯体31包括连通孔314，所述连通孔314位于所述第一子通道211与第二子通道212之间；所述活动杆组件32与所述芯体31配合截断所述连通孔314与所述第二子通道212或者导通所述连通孔314与所述第二子通道212。具体地，芯体31设置有第一中部通孔312，活动杆组件32伸入该第一中部通孔312且可相对该芯体31作轴向移动，使得阀芯部件3导通或阻断第一子通道211与第二子通道212。

活动杆组件32包括活动杆321、弹性件322和凸伸部323，弹性件322和凸伸部323相对位于活动杆321两侧，且位于芯体31的两侧部。

所述第一限位部222与所述弹性件322位于所述阀芯部件3的同一侧位置，如此，经换热芯体1出来的流体对弹性件322施力，使得第一子通道211和第二子通道212连通，此处同一侧位置是指相对阀芯部件3的中心线而言，两者位于阀芯部件3的中心线的同一侧，阀芯部件3的中心线包括沿着第一安装孔道21的方向和大致垂直第一安装孔道21的方向的中心线，此处是指大致垂直第一安装孔道21的中心线。
作为另一种实施方式，活动杆组件32包括卡簧324，活动杆321端部位置设置凹槽3211，卡簧324限位于该凹槽3211，且弹性件322的端部与卡簧324相抵。
凸伸部323的尺寸大于第一中部通孔312，凸伸部323具有第一密封部位3231，第一密封部位3231朝向基体部311的第二侧部3112，基体部311的第二侧部3112设置有第二密封部位3113，第一密封部位3231能够与第二密封部位3113接触设置；第一密封部位3231的至少部分与第一中部通孔312的中心线之间的距离大于阀口3140的中心线与第一中部通孔312的中心线之间的距离D，如此第一密封部位3231可阻断阀口3140与第二子通道212的导通。此处第一密封部位3231与第二密封部位3113之间的密封可以通过线密封或面密封来实现。
应当了解，第一密封部位3231的至少部分与第一中部通孔312的中心线之间的距离大于阀口3140与第一中部通孔312的中心线之间的距离D，在阀芯部件3周向方向，第一密封部位3231具有相较阀口3140离第一中 部通孔312的中心线距离更远的部分以及距离更近或一样的部分。
更为具体地，基体部311的第二侧部3112设置突出部3114，突出部3114位于阀口3140的外周区域，突出部3114与第一密封部位3231相配合设置，在不受力的情况下，突出部3114与第一密封部位3231相抵。
活动杆321相对芯体31具有第一位置和第二位置，当活动杆321位于第一位置，第一密封部位3231与第二密封部位3113接触且密封设置，连通孔314与第二子通道212不连通。当活动杆321位于第二位置，第一密封部位3231与第二密封部位3113之间留有空隙，连通孔314与第二子通道212连通。
凸伸部323包括封闭部3232和支承部3233，封闭部3232自支承部3233周向延伸凸出，封闭部3232设置第一密封部位3231。作为一种实施方式，封闭部3232与支承部3233为一体设置，封闭部3232凸出于支承部3233设置。本文中，封闭部3232是指该部与其他零件配合后实现封闭功能，其封闭结构样态可以为面封闭形式，也可以为线封闭形式，或者也可以为凹凸结构等配合形式，或者其他各种实现封闭功能的结构。作为另一种实施方式，封闭部3232与支承部3233为分体设置，封闭部3232包括封闭件3234和压件3235，封闭件3234设置第一密封部位3231，封闭件3234套于支承部3233的端部，压件3235与封闭件3234组装固定，例如通过铆压等方式。本文中，除非另有指明，一体设置表示部件是通过一体成型形成的，分体设置表示部件是通过分体成型形成的，分体设置是针对部件单独形态而言，并不排除部件组装成一体结构。
参照图4，端口23与第一孔道12连通，第一限位部222具有内侧2221和外侧2222，其中内侧和外侧是相对于第一安装孔道21的中心线而言，此处定义第一限位部222的内侧相对邻近第一安装孔道21的中心线，第一限位部222的外侧相对远离第一安装孔道21的中心线，作为一种具体的实施方式，安装块2形成端口23的壁部与第一安装孔道21的中心线之间的距离L1大于第一限位部222的内侧2221与第一安装孔道21的中心线之间的距离L2，安装块2包括设置于第一安装孔道21壁部22的导向部221，导向部221自第一限位部222向着端口23延伸设置，除与第一限位部222连接的点外，导向部221上各处与第一安装孔道21的中心线之间的距离大 于第一限位部222的内侧与第一安装孔道21的中心线之间的距离L2。本文中，定义第一安装孔道21为阀芯部件3未组装在安装块2内部时所呈现的，在阀芯部件3安装于第一安装孔道21后，第一限位部222的内侧相对邻近第一安装孔道21的中心线，此处第一安装孔道21的中心线为未组装阀芯部件3状态时第一安装孔道21的中心线，本文所提第一安装孔道21的中心线均作上述理解。
导向部221向着端口23延伸设置包括导向部221延伸至端口23，也包括导向部221延伸至第一安装孔道21壁部位于端口23的内部。
作为另一种具体的实施方式，安装块2形成端口23的壁部与第一安装孔道21的中心线之间的距离L1大致等于第一限位部222的内侧与第一安装孔道21的中心线之间的距离L2，此处定义大致为±5％的数值范围。
参照图2，在流体控制组件10填充有流体的时候，流体自第二安装孔道21’流入，并经过第二孔道13、第一流体通道11、第一孔道12，流体对活动杆组件32施力，使得活动杆组件32相对芯体31作沿第一安装孔道21的轴线方向运动，流体通过阀芯部件3的连通孔314进入到第二子通道212，并从第二接口102流出。
作为一种具体的实施方式，阀芯部件3的至少部分位于第一孔道12，如此可以降低安装块2的高度，使得流体控制组件10的整体结构更为小巧紧凑。
作为另一种具体的实施方式，阀芯部件3位于第一安装孔道21，阀芯部件3不伸入第一孔道12，不影响换热芯体1内的流体的流动方向。
第一孔道12与第二孔道13位于换热芯体1的同一侧位置，当然第一孔道12与第二孔道13还可位于换热芯体1的对角位置。
参照图16和图17，图16、图17示意出流体控制组件另外的实施方式的结构图。
所述流体控制组件10’包括换热芯体1、安装块2、阀芯部件3，调节阀部件4和传感器部件5，换热芯体1与安装块2焊接固定，阀芯部件3与安装块2限位设置，传感器部件5与安装块2螺纹连接。传感器可以测量所述流体控制组件10’中的温度或/和压力，将测量数据传送给空调控制器或汽车控制器，有利于控制器精确且快速的控制调节阀部件4的节流孔 的开度以及其他流体控制组件，利于提高制冷***或电池冷却***的运行稳定性以及调控的灵活性。
所述传感器部件5可以为仅探测压力的传感器部件或者仅探测温度的传感器部件，其具有压力感测部或温度感测部，该压力感测部或温度感测部位于所述传感器孔道内；届时可根据压缩机转速或者其它参数推算另外一个状态量的值，使用这种传感器可以在满足车企要求的情况下降低成本，简化传感器结构。
所述传感器部件5也可以为同时探测压力与温度的传感器部件。即所述传感器部件具有温度压力感测部，该温度压力感测部位于所述传感器孔道内。可以提高测量精确度，所述传感器部件的控制效果优于单一测量温度或压力的传感器部件。
安装块2包括传感器孔道27，传感器孔道27与第一安装孔道21连通。在第一安装孔道21的轴线方向，传感器孔道27相对第一限位部222更为靠近端口23，即传感器通道27与第一安装孔道21的连通口位于端口23与第一限位部222之间。
由于阀芯部件3与安装块2形成第一安装孔道21的壁部22密封设置，为保证阀芯部件3与安装块2之间的密封效果，阀芯部件3在第一安装孔道21的轴向方向上位于传感器孔道27的上方，使得阀芯部件3与安装块2之间的密封不会因传感器孔道27而受影响。此处以安装块2设置换热芯体1之处为下，以与下相对方向为上。
第一安装孔道21与传感器孔道27的一端连通，传感器孔道27的一端与第一安装孔道21的连通部位于第一子通道211。安装块2设置传感器孔道27的壁部设有内螺纹，所述传感器部件5与所述传感器孔道27壁部通过螺纹固定。所述传感器部件5与所述传感器部件5的至少一部分位于所述传感器孔道27内；
所述传感器部件5与所述安装块2的连接方式不限于螺纹连接，也可以使用其他连接方式。
