具体实施方式
参照图1、图2，图1、图2示意出一种换热组件100，换热组件100包括换热器芯体1和阀组件2，换热器芯体1与阀组件2固定设置。换热器芯体1具有多个堆叠设置的板片11，相邻各板片11焊接固定，各板片11至少具有第一孔口和第二孔口，沿着板片的堆叠方向，各板片11的第一孔口对齐设置，各板片11的第二孔口对齐设置。第一孔口、第二孔口位于板片11的邻近边缘位置，如此流经板片的流体可以具有较长的流动路线，有助于提高换热效率。
参照图2-图10，换热器芯体1至少具有第一流道12和第二流道13，其中第一流道12与第二流道13内流体可以在换热器芯体1内部换热；换热器芯体1也还可以具有第三流道或第四流道。所述换热器芯体1包括层叠设置的多个第一类板、多个第二类板，所述第一类板和第二类板层叠形成所述第一流道12和所述第二流道13；所述第一类板包括第一孔口、第二孔口、第三孔口；所述第二类板包括第一孔口、第二孔口，所述第二类板不具有所述第三孔口，沿着所述换热器芯体1的长度或者宽度方向，所述第三孔口位于所述第一孔口与所述第二孔口之间；其中在换热器芯体1的长度或者宽度方向，第三孔口位于第一孔口与第二孔口之间是指第一孔口与第二孔口可以不对齐，但是例如在换热器芯体1的长度方向，第三孔口可以位于第一孔口与第二孔口之间的一个区域，或者例如在换热器芯体1的宽度方向，第三孔口可以位于第一孔口与第二孔口之间的一个区域。
换热器芯体1包括第一部分流体路径121、板间路径122和第二部分 流体路径123、第三部分流体路径1224，第一部分流体路径121形成于第一类板、第二类板的第一孔口处，第二部分流体路径123形成于第一类板、第二类板的第二孔口处，第三部分流体路径1224形成于所述第一类板的第三孔口处，板间路径122连通第一部分流体路径121、第二部分流体路径123、第三部分流体路径1224。由于相邻板片11堆叠会至少形成有两种流体的板间路径，此处板间路径122特指相邻板片11之间的流体路径，且这个流体路径是第一流道的一部分，与第一部分流体路径121、第二部分流体路径123、第三部分流体路径1224连通。本文中，第一部分流体路径121包括(但不限于)一个通道，可以具有两个或以上通道，第二部分流体路径123包括(但不限于)一个通道，可以具有两个或以上通道。
阀组件2包括阀体21、阀芯部件22、传感器23、电路板24，阀体21具有第一腔211和第二腔212，阀芯部件22的至少部分位于第一腔211，传感器23的至少部分位于第二腔212，传感器23感测第一流道的温度和/或压力，在本实施方式中，第二腔212可以与板间路径122连通，传感器23能感测板间路径122的温度和/或压力；传感器23与电路板24电连接。
在图中所例示结构中，传感器23伸入换热器芯体1；当然，传感器23也可以不伸入换热器芯体1，传感器23可以位于换热器芯体1上方，传感器23所在的第二腔212与板间路径122连通，用于传感器23收集流经换热器芯体1的流体的压力和/或温度。传感器23伸入到换热器芯体1可以进一步降低传感器23凸伸出换热器芯体1的高度，有利于降低尺寸。
换热组件具有伸入部213，伸入部213位于第一部分流体路径121或者所述第三部分流体路径1224，所述阀芯部件22的至少部分位于所述伸 入部213，所述阀芯部件22的一部分和所述伸入部213内壁密封设置。
在本实施方式中，伸入部213位于第一部分流体路径121，阀芯部件的至少部分伸入到伸入部213内腔，阀芯部件与伸入部213内壁密封设置。
阀芯部件22包括阀芯221、转子组件222、定子组件223，定子组件223套于转子组件222的外周，定子组件223与电路板16电连接；阀组件2还具有阀口220，阀口220能够连通位于阀口220两侧的流通通道；本实施例中，阀体21还包括阀座224，阀座224设置于阀芯221的外周并限位设置，阀口220成形于阀座224，阀芯221通过靠近和远离阀口220改变工作介质在阀口220处的流通截面积，进而能够在阀口220处形成节流。阀组件2工作时，通过控制通过定子组件223的绕组中的电流按照预定的规律变化，从而控制定子组件223产生变化的激励磁场，转子组件222在激励磁场的作用下转动，转子组件222能够带动阀芯221相对阀口220运动，并调节阀口220的开度；这样转子组件能够带动阀芯221相对阀口220运动，这种采用控制通过定子组件的电流的方式控制阀芯221相对于阀口220的开度的方式，有利于提高对流量的控制精度。
阀体21与换热器芯体1焊接固定，作为一种实施方式，换热器芯体1包括顶板113、多个中间板114、底板115，多个中间板114位于顶板113与底板115之间，顶板113、多个中间板114、底板115焊接固定，阀体21与顶板113焊接固定，或者阀体21与底板115焊接固定。作为其他实施方式，换热器芯体包括连接体、顶板、多个中间板、底板，多个中间板位于顶板与底板之间，顶板、多个中间板、底板焊接固定，阀体与连接体焊接固定，连接体与顶板焊接固定或者连接体与底板焊接固定。作为其他 实施方式，换热器芯体包括连接体、顶板、多个中间板、底板，多个中间板位于顶板与底板之间，顶板、多个中间板、底板焊接固定，连接体与底板焊接固定，阀体与顶板焊接固定。作为其他实施方式，换热器芯体包括连接体、顶板、多个中间板、底板，多个中间板位于顶板与底板之间，顶板、多个中间板、底板焊接固定，连接体与顶板焊接固定，阀体与顶板焊接固定。连接体可以是连接板的形式，连接体也可以是连接块的形式。
在图中所例示结构中，伸入部213与阀体21一体形成，阀体21包括第一侧部214和第二侧部215，第一侧部214与阀芯部件配合设置，第二侧部215与换热器芯体1配合设置，第二侧部215与换热器芯体1焊接固定。伸入部213为阀体21的一部分，第二侧部215凸出设置有伸入部213，第一腔211贯穿伸入部213，第一腔211贯穿第一侧部214与第二侧部215，第二腔212贯穿第一侧部214与第二侧部215。
在本实施方式中，伸入部213是阀体21的一部分，第一腔211贯穿伸入部213是指阀体在未装配时，内部设置有第一腔211的空间，第一腔111贯穿第一侧部214和第二侧部215是指阀体未装配时，第一腔211在第一侧部214和第二侧部215侧都有开口。以下相似描述作类似解释。
伸入部213与阀体21之间可以是加工后一体形成，也可以是分体焊接等方式组装成一体结构。伸入部213和第二侧部215的划界是以是否凸出且位于换热器芯体1内部来区分。
阀体21具有第一通孔216，第二侧部215具有第一槽2151，第一槽2151连通第一通孔216与第一腔211。在第二侧部215与换热器芯体1焊接固定时，第一槽2151与换热器芯体1配合形成一个流道。
伸入部213具有端口部2131和根部2132，根部2132具有缺口2133，缺口2133与第一槽2151连通，阀芯部件具有阀座224，阀座224设置有节流进口2240，节流进口2240开设于阀座224周壁，缺口2133的流通面积大于节流进口2240的流通面积。
根部2132的缺口2133沿着板片11的堆叠方向的开口深度大于第一槽2151，缺口2133部分位于换热器芯体1内部，如此，在阀芯部件位于伸入部213中时，在节流进口2240位于换热器芯体1内部时，图上可以看出位于顶板113的下方时，缺口2133的开口深度大于第一槽2151，可以使得流体从第一槽2151流入后经较深深度的缺口2133进入节流进口2240，如此可以将阀芯部件伸入到换热器芯体1的更深的内部，有助于降低阀组件凸伸出换热器芯体1的高度，降低尺寸。
换热组件100包括引流管3，引流管3位于第一部分流体路径121，阀芯部件包括节流出口通道2241，引流管3内腔与节流出口通道2241连通，第一部分流体路径121包括第一子路径1211和第二子路径1212，第一子路径1211与引流管3内腔连通，第二子路径1212位于引流管3外部；

所述换热器芯体1包括第三挡部14，第三挡部14位于第一部分流体路径121，第一部分流体路径121包括第一子路径1211和第二子路径1212，第一子路径1211与引流管3内腔连通，第二子路径1212位于引流管3外 部；第三挡部14分隔第一子路径1211和第二子路径1212。
所述板间路径122至少包括第一换热区1221、第二换热区1222和第三换热区1223，所述第一子路径1211与所述第一换热区1221连通，所述第一换热区1221与所述第三子路径1231连通，所述第三子路径1231与所述第二换热区1222连通，所述第二换热区1222与所述第二子路径1212连通，所述第二子路径1212与所述第三换热区1223连通。
换热器芯体1的顶板113参照图8，换热器芯体1的顶板113包括第一孔口113a、第二孔口113b、第三孔口113c、第四孔口113d、第五孔口113e，第一孔口113a用于形成第一部分流体路径121，第二孔口113b用于形成第二部分流体路径123。第三孔口113c与第二腔212连通，第四孔口113d、第五孔口113c与第二流体通道13连通，第一流道12与第二流道13内的流体在换热器芯体1内部进行换热。
换热器芯体1的中间板114具有第一类板1141和第二类板1142，换热器芯体1的第一类板1141参照图9，换热器芯体1的第二类板1142参照图10。作为一种例示，换热器芯体1的第一类板1141包括第一孔口1141a、第二孔口1141b、第三孔口1141c、第四孔口1141d、第五孔口1141e，第一孔口1141a、第二孔口1141b、第四孔口1141d、第五孔口1141e位于板片的邻近边缘位置，相对于第一孔口1141a、第二孔口1141b，第三孔口1141c位于板片的邻近中心位置，在板片的长度方向，第三孔口1141c位于第一孔口1141a、第二孔口1141b之间。第三孔口1141c用于形成第三部分流体路径1224，传感器23可以插入第三孔口1141c。
第一类板1141具有多个第一板片1144和多个第二板片1145，第一板 片1144与第二板片1145相互堆叠形成板间路径122，第一板片1144的第一孔口1141a周边具有第一台阶部1146a，第一台阶部1146a相对第一板片1144的板平面1147凸出，第一板片1144的第二孔口1141b周边具有第二台阶部1146b，第二台阶部1146b相对第一板片1144的板平面1147凸出，第一板片1144的第三孔口1141c周边具有第三台阶部1146c，第三台阶部1146c相对第一板片1144的板平面1147凸出，第一孔口、第二孔口、第三孔口流经的流体为同一流体。第三台阶部1146c与第一台阶部1146a高度相同，第三台阶部1146c与第二台阶部1146b高度相同。如此，在板片堆叠后，第三台阶部、第二台阶部、第一台阶部可以相应地隔离第一孔口、第二孔口、第三孔口与该板片的板平面流体路径，由于传感器/或阀芯部件(伸入部)会插入到第三孔口，因此对第三孔口周边的密封性有一定的要求，如果泄露就会导致整个换热组件失效，因此在第三孔口周边设置与第一孔口、第二孔口相同高度的第三台阶部，第三台阶部与相邻的板片结构焊接固定，可以有效解决密封性。第一板片1144的第四孔口1141d周边结构与第一板片1144的第五孔口1141e周边结构类似，第四孔口1141d与第五孔口1141e流经的流体为同一流体。
第一类板1141的第二板片1145的第一孔口1141a周边设置有第一凹环1148a，第二孔口1141b周边设置有第二凹环1148b，第三孔口1141c周边设置有第三凹环1148c，第二板片1145的凹环结构与第一板片1144的台阶部结构相配合，以形成流道的隔离。
