请参阅图3-11。热管理装置1000包括换热芯体和节流单元1300，换热芯体包括多个堆叠的板片、第一板体1140和第二板体1210，沿板片的堆叠方向，这些板片位于第一板体1140和第二板体1210之间。具体地，换热芯体包括第一换热部1100、连接板体1400以及第二换热部1200，在本实施方式，第一板体1140是第一换热部1100的一部分，第二板体1210是第二换热部1200的一部分，第一换热部1100还包括顶板，第一换热部1100的若干板片自第一板体1140堆叠至顶板。第二换热部1200还包括底板，第二换热部1200的若干板片自底板堆叠至第二板体1210。连接板体1400位于顶板和底板之间，并与顶板和底板焊接固定。在其他实施方式，换热芯体也可以不设置顶板和底板，连接板体1400直接与第一换热部1100的板片、第二换热部1200的板片焊接固定。需要说明的是，为方便介绍，定义第二换热部1200位于第一换热部1100的上方。当然也可以不设置连接板体1400，换热芯体为一组结构，换热芯体包括第一板体1140和第二板体1210，以及沿板片的堆叠方向，位于第一板体1140和第二板体1210之间的多个堆叠的板片，沿板片的堆叠方向，这些板片位于第一板体1140 和第二板体1210之间，若干板片自第一板体1140堆叠至第二板体1210，或者说，若干板片自第二板体1210堆叠至第一板体1140。
第一换热部1100和第二换热部1200均包括多个堆叠的板片，第一换热部1100的板片和第二换热部1200的板片结构可以相同，以第一换热部1100的板片介绍为例介绍板片结构。在第一换热部1100中，相邻的板片堆叠后形成第一板间通道和第二板间通道，除最靠近第一板体1140和顶板的两片板片外，内侧板片的一侧为第一板间通道，内侧板片的另一侧为第二板间通道，本实施例中，相邻的板片结构相同，为了便于描述，相邻的两个板片中的一个定义为第一板片，另一个定义为第二板片，如第一板片及与该板片相邻的两片第二板片的其中之一形成第一板间通道，与其中另一第二板片则形成第二板间通道，第一板间通道和第二板间通道相对不连通。第一板间通道的流体和位于第二板间通道的流体能够热交换。这里需要说明的是，第一板间通道和第二板间通道相对不连通指在第一换热部1100的内部不连通，热管理装置1000成为热管理系统的一部分后，则可能存在第一板间通道和第二板间通道连通的情况。这里所述的连接板体、顶板、底板的主体部的厚度比板片的主体部的厚度大，具有增强热管理装置1000机械强度的作用。
热管理装置1000具有制冷剂流道、冷却液流道、第一入口1001、第一出口1002、第二入口1003和第二出口1004，制冷剂流道连通第一入口1001和第一出口1002，也即，第一入口1001是制冷剂流道的入口，第一出口1002为制冷剂流道的出口；冷却液流道连通第二入口1003和第二出口1004，也即第二入口1003是冷却液流道的入口，第二出口1004为冷却液流道的出口。其中，第二出口1004、第二入口1003和冷却液流道成形于第二换热部1200，第一出口1002和第一入口1001成形于第一换热部1100，沿板片的堆叠方向，第二出口1004、第二入口1003位于热管理装置1000的一侧，第一出口1002和第一入口1001位于热管理装置1000的相对另一侧。第一入口1001、第一出口1002可以成形于与第一板体1140固定连接的管或块，第二入口1003和第二出口1004可以成形于与第一板体1140固定的管或块，在其他实施方式，第一入口1001、第一出口1002可以成形于第一板体1140，第二入口1003和第二出口1004可以成形于第 二板体1210。

第一换热部1100至少具有第五孔道1160、第二孔道1120、第三孔道1130和第四孔道1150，以上孔道沿第一换热部1100的板片堆叠方向延伸。第一流道包括第五孔道1160、位于板片之间的第一板间通道以及第二孔道1120，第一换热部1100的第一板间通道连通第五孔道1160、第二孔道1120。在本实施方式，第一入口1001与第五孔道1160连通，在热管理装置1000工作时，制冷剂由第一入口1001进入第五孔道1160，而后进入第一换热部1100的第一板间通道，与第一换热部1100的第二板间通道的制冷剂热交换后，再进入第二孔道1120，第二孔道1120在第一换热部1100的顶板具有开口，制冷剂由第一换热部1100的顶板的开口离开第一换热部1100。第二流道包括第三孔道1130、位于板片之间的第二板间通道以及第四孔道1150，第一换热部1100的第二板间通道连通第三孔道1130和第四孔道1150。第一出口1002与第四孔道1150连通，在热管理装置1000工作时，第二流道的制冷剂由第三孔道1130进入第一换热部1100的第二板间通道与第一板间通道的制冷剂热交换后，而后进入第四孔道1150，第四孔道1150的制冷剂由第一出口1002排出热管理装置1000。
第二换热部1200的第一板间通道是第三流道的一部分，第二换热部1200的第二板间通道是冷却液流道的一部分。第二换热部1200至少包括第一孔道1240、第六孔道1230、第七孔道1260和第八孔道1270，其中，第一孔道1240、第六孔道1230为第三流道的一部分，第七孔道1260和第八孔道1270为冷却液流道的一部分。第三流道包括第一孔道1240、第六孔道1230，位于第二换热部1200的第一板间通道，第二换热部1200的第一板间通道连通第一孔道1240和第六孔道1230。冷却液流道包括第七孔道1260、位于第二换热部1200第二板间通道以及第八孔道1270，第二换热部1200的第二板间通道连通第七孔道1260和第八孔道1270。在本实施方式，第二入口1003与第七孔道1260连通，第二出口1004与第八孔道 1270连通，热管理装置1000工作时，冷却液由第二入口1003进入第七孔道1260，而后进入第二换热部1200的第二板间通道，并与第三流道的制冷剂热交换，再进入第八孔道1270，最后由第二出口1004排出热管理装置1000。
请参阅图4、图5以及图7及图8，沿板片堆叠方向，连接板体1400位于第一换热部1100和第二换热部1200之间，具体地，第一换热部1100包括第一壁1110，第二换热部1200包括第二壁1220，在本实施方式，第一壁1110成形于第一换热部1100顶板，第二壁1220成形于第二换热部1200底板，连接板体1400的下侧壁与第一壁1110焊接固定，连接板体1400的上侧壁与第二壁1220焊接固定。第一壁1110和第二壁1220相对设置，这里所述的相对设置包括间接相对设置和直接相对设置，间接相对设置指第一壁1110和第二壁1220之间有其他物体，如连接板体1400，第一壁1110和第二壁1220之间也可以不设置连接板体1400，也即直接相对设置，第一壁1110和第二壁1220焊接固定。连接板体1400还包括第一通孔1410和第二通孔1420，第一通孔1410和第二通孔1420贯穿连接板体1400，并且第一通孔1410和第二通孔1420在连接板体1400的上壁和下壁分别具有开口，第二通孔1420连通第六孔道1230和第三孔道1130，也即第二通孔1420连通第三流道和第二流道。具体地，第六孔道1230在第二壁具有第二开口1231，至少部分第二开口1231朝向第二通孔1420并与第二通孔1420连通。第三孔道1130在第一壁具有第一开口1131，至少部分第一开口1131朝向第二通孔1420，第一开口1131通过第二通孔1420与第二开口1231连通，这样，第三孔道1130通过第二通孔1420与第六孔道1230连通。在本实施方式，第一开口1131和第二开口1231相错设置，第二通孔1420呈狭长延伸，这样有利于制冷剂在第二通孔1420处的流通更顺畅，当然，第一开口1131和第二开口1231也可以相对设置。第三流道的制冷剂与冷却液流道的冷却液在第二换热部1200热交换之后经第二通孔1420进入第一换热部1100的第二流道，而后在第一换热部1100与第一流道的制冷剂热交换。
第一通孔1410与第二孔道1120连通，具体地，第二孔道1120在第一壁1110形成第一连通口1121，至少部分第一连通口1121面向第一通孔 1420，且与第一通孔1420连通。当然，第一壁1110和连接板体1400的相应位置之间密封设置，以防止制冷剂从第一换热部1100和连接板体1400的连接处泄露，第二壁1220和连接板体1400的相应位置之间密封设置，以防止制冷剂从第二壁1220和连接板体1400连接处泄露。另外，本实施例中，连接板体1400还包括两个方形孔1430，该方形孔1430的作用在于减轻连接板体1400重量，进而减轻热管理装置1000的重量；该两个方形孔1430较第一通孔和第二通孔大，方形孔1430还具有减少第一换热部1100和第二换热部1200之间热传导作用；两个方形孔1430位于连接板体1400的靠近中间位置，第一换热部1100和第二换热部1200的中间位置温差较大区域，不仅有利于降低热传导，也有利于热管理装置的质量分布均衡。

请参阅图10以及图11，第二换热部1200包括第一隔板1280，第一隔板1280与第二换热部1200的一个板片为一体结构，沿第一孔道1240的轴向，第一隔板1280形成第一孔道1240的底壁，第一隔板1280包括容纳管体1500的通孔，第一隔板1280的壁与管体1500的壁固定，并在第一隔板1280的壁与管体1500的壁之间密封设置。另外，第二换热部1200还包括第二隔板1281，第二隔板1281比第一隔板1280靠近节流单元1300，第二隔板1281位于第一孔道1240，第二隔板1281与第二换热部1200的一个板片一体结构，第二隔板1281同样具有容纳管体的通孔，第二隔板1281的壁与管体1500的外壁密封设置，这样第二隔板1281可以改变制冷剂流向，使第二换热部1200具有多个流程。
请参阅图7以及图8，结合图1所示意的热管理系统，介绍热管理装置1000工作方式。热管理系统包括压缩机100、冷凝器200以及热管理装 置1000，压缩机100的出口通过冷凝器200与热管理装置1000的第一入口1001连通，热管理装置1000的第一出口1002与压缩机100的入口连通。热管理系统还包括第一换热器400以及泵300，热管理装置1000的第二入口1003通过第一换热器400、泵300与热管理装置的第二出口1004连通，或者进一步说，热管理装置1000的冷却液流道、第一换热器400、泵300形成冷却液系统或者冷却液系统的一部分，冷却液在泵300的驱动下在冷却液系统内流动。热管理系统工作时高温高压的制冷剂在冷凝器200释放热量，相对低温高压的制冷剂由第一入口1001进入热管理装置1000的制冷剂流道，也即第一换热部1100的第一流道，而后进入管体1500的腔，制冷剂经阀口1351节流降压后进入阀腔1330，而后进入第一孔道1240，也即第三流道，制冷剂在第三流道吸收冷却液的热量，降低冷却液的温度，而后进入第六流道1230，第三流道的制冷剂经连接板体1400的第二通孔1420进入第二流道，而后由第一出口1002排出热管理装置1000。第二流道的制冷剂与第一流道的制冷能够在第一换热部1100热交换，进一步降低了第一流道内的制冷剂温度，提高第二流道内制冷的温度，有利于减少压缩机液击。冷却液流道的冷却液进入第一换热器400，用于降低电池或者其他设备的温度。热管理装置1000包括第一换热部1100和第二换热部1200，第一换热部1100和第二换热部1200通过连接板体1400固定，第一换热部1100为制冷剂-制冷剂换热，第二换热部1200为制冷剂-冷却液换热，第一换热部1100的制冷剂通过管体1500与节流单元1300连通，管体1500内置于热管理装置1000，节流单元1300与第二换热部1200的第二板体固定，节流后的制冷剂在第二换热部1200与冷却液热交换，降低冷却液的温度，管体1500内置于热管理装置1000，相对减少了热管理装置沿板片堆叠方向的长度，或者说，减小热管理装置1000的体积，也能够有效降低外界对管体的损害，以利于提高热管理装置的寿命。
请参阅图2以及图12，图2示意热管理系统的另一实施方式。在本实施方式，与图1的实施方式相比，热管理装置1000还包括第三出口1005和第三入口1006，其中，第三出口1005与第二孔道1120连通，这样第二孔道1120的制冷剂不仅可以通过管体1500进入节流单元1300，也可以由第三出口1005排出。第三入口1006与第三孔道1130连通，也即流入第三 孔道1130的制冷剂不仅有从第二换热部1200流入的制冷剂，也有从第三入口1006流入的制冷剂。在本实施方式，热管理装置1000的第一流道的制冷剂可以由管体1500进入节流单元1300，也可以由第三出口1005进入节流元件500，节流元件500节流后进入第二换热器600吸收外界热量，而后制冷剂经第三入口1006进入热管理装置的第一换热部1100，最后由第一出口1002排出，进入压缩机100。热管理装置1000在第一换热部1100增加第三出口1005和第三入口1006，这样可以使第二换热器600作为新增的蒸发器连入热管理系统，热管理装置1000的集成度更高。
请参阅图13，图13示意的方案为热管理装置不包括连接部1340的示意图。管体1500的第一端部所形成的腔容纳至少部分阀口部1350，阀口部1350的侧壁与第一端部的壁之间密封设置。当然，在其他方式，阀口部1350包括连通腔，阀口1351位于连通腔的上方，阀口1351与连通腔连通，管体1500的第一端部位于连通腔内，管体1500的第一端部的外壁与形成连通腔壁固定连接并在连接处密封。这样，阀口1351与管体1500的腔连通。由于没有连接部1340，节流后的制冷剂进入阀腔1330后直接进入第一孔道1240，不仅减少零部件，也减少了安装步骤。图13所示意的阀口部1350以及管体1500的第一端部位于第一阀体的第一贯通孔1311内，阀口部1350以及管体1500的第一端部固定后也可以位于第一孔道1240内，这样，沿第一孔道1240的径向，第一阀体的长度能够降低，热管理装置的体积相对小巧。
请参阅图20，热管理装置也可以不包括连接板体1400，相同部分请参阅图7，管体1500的第二端部位于第一连通口1111，并且管体1500的第二端部的外壁与形成第一连通口1111的壁之间密封设置，这样第二孔道1120的制冷剂能够进入管体1500的腔；第二壁1220具有第二连通口1221，第二连通口1221容纳管体1500，第一隔板1280可以是第二壁1220的一部分，或者是与第二壁1220相邻板片的一部分，这样第一孔道1240的制冷剂不会泄漏到第一换热部1100和第二换热部1200之间。当然，为增加管体1500与第一连通口1111的壁密封面，第一连通口1111的壁可以是相对第一壁1110主体的凸起。相比于热管理装置1000具有连接板体1400，本实施方式的重量较轻，体积较小。
请参阅图14-图16，与图7所示意的实施方式相比，热管理装置1000未单独设置管体1500，第二换热部1200的第一板片包括至少一个第一孔口1204和第二孔口1205，形成第二孔口1205的壁包括第一翻边1290，第一翻边1290自第二换热部1200的第一板片的主体朝向节流单元1300折翻，第一翻边1290插入与其相邻上侧的第一翻边内，并且相邻的两个第一翻边1290之间密封设置，多个板片的第一翻边1290的内壁形成第四流道的壁，与阀口部1350相邻的第一翻边1290部分位于容纳部1341内，这样第四流道与阀口1351连通，与阀口部1350相邻的第一翻边1290与容纳部1341的壁之间密封设置。沿第一孔道的径向，第二孔口1205的外侧分布有四个第一孔口1204，而第一孔口1204形成第一孔道1240。在其他实施方式，每个板片内包括至少一个第一孔口1204。第三开口1312面向第一孔道1240，实现阀腔1330与第一孔道1240的连通。在其他实施方式，连接部1340也可以插入第一翻边1290的内壁且密封固定。节流单元1300不包括连接部1340时，阀口部1350可以直接与第一翻边1290的内壁或者外壁密封固定，以实现阀口1351与第四流道的连通。可以知道，在第二换热部1200的板片，最靠近第一换热部1100的板片包括第二孔口和第一隔板1280，而不包括第一孔口，第一隔板1280为第一孔道1240的底壁。
请参阅图17-图19，在本实施方式，第一阀体1310与第二板体1210固定连接，第二板体1210具有容纳部分第一阀体1310的开口，第一贯通孔1311在第一阀体1310的底壁具有第三开口1312并且第三开口1312面向第一孔道1240，第一贯通孔1311具有容纳阀口部1350的腔，阀口部1350的侧壁与第一贯通孔1311的内壁之间密封设置，第四流道位于换热芯体外侧。

在一种具体的实施方式，请参阅图18，第一板体1140包括板体部1144和凸起部1141，板体部1144大致与板片平行，第二过渡通道1105在板体部的上壁具有面向第二孔道1120的开口，凸起部1141相对板体部1144凸出于换热芯体，凸起部1141可以与板体部1144一体结构或者焊接为一体，第二过渡通道1105在凸起部1141具有第一连接口1142、第二连接口1143，第一连接口1142位于凸起部1141的侧壁，第二连接口1143面向第二孔道1120，第二端部1530与第一连接口1142的壁之间密封固定。第二孔道1120通过第二连接通道1105与管体1500的腔连通，进而与节流单元1300的阀腔1330连通；第二连接口1143也可以与其他外部器件连接，这时第二连接口1143也即第三出口1105，这样，第二孔道1120也可以与其他部件连通。第二过渡通道1105在凸起部1141也可以仅具有第一连接口1142，第一连接口1142可以面向第二孔道1120，第一连接口1142位于凸起部1141的侧壁。另外，第一板体1140不包括凸起部，不再详细描述。
