鉴于上述问题，本申请提供一种多通阀、换热***以及车辆，能够增加换热回路的可切换模式的种类，提升热管理***不同换热模式切换的速度。In view of the above problems, the present application provides a multi-way valve, a heat exchange system and a vehicle, which can increase the types of switchable modes of the heat exchange circuit and improve the speed of switching between different heat exchange modes of the thermal management system.

第一方面，本申请提供了一种多通阀，包括外壳以及转动阀芯。外壳具有容纳腔，外壳设有接口区，接口区上设有多个接口。转动阀芯容纳于外壳内并可转动地连接于外壳。转动阀芯具有多个互不连通的子腔体，多个子腔体沿转动阀芯的周向布置；转动阀芯被配置为通过旋转使不同的子腔体与接口区相对，多个子腔体用于使接口区的多个接口以不同的方式连通。In a first aspect, the present application provides a multi-way valve, comprising a housing and a rotating valve core. The housing has a receiving cavity, and the housing is provided with an interface area, and the interface area is provided with a plurality of interfaces. The rotating valve core is accommodated in the housing and rotatably connected to the housing. The rotating valve core has a plurality of sub-cavities that are not connected to each other, and the plurality of sub-cavities are arranged along the circumference of the rotating valve core; the rotating valve core is configured to make different sub-cavities face the interface area by rotation, and the plurality of sub-cavities are used to make the plurality of interfaces in the interface area connected in different ways.

本申请实施例的技术方案中，外壳中设有容纳器用以容置转动阀芯，并且，在外壳上设置有接口以实现转动阀芯与其他换热设备或换热管道的连接。进一步的，通过将外壳与安装座进行固定，能保证转动阀芯转动过程的稳定性，以提高多通阀转换过程的效率。设置转动阀芯以形成多个子腔体，子腔体能够将多个接口以不同的方式进行连通，以实现换热***中不同换热管道的连通模式。换热***能够根据不同的环境温度或车辆行驶的不同状况选择合适的换热模式，通过旋转转动阀芯即可实现对接口与不同的换热流道之间的连接的控制，结构简单，便于操作。In the technical solution of the embodiment of the present application, a container is provided in the housing to accommodate the rotating valve core, and an interface is provided on the housing to realize the connection between the rotating valve core and other heat exchange equipment or heat exchange pipes. Furthermore, by fixing the housing and the mounting seat, the stability of the rotating valve core during rotation can be ensured to improve the efficiency of the multi-way valve conversion process. The rotating valve core is provided to form a plurality of sub-cavities, and the sub-cavities can connect a plurality of interfaces in different ways to realize the connection mode of different heat exchange pipes in the heat exchange system. The heat exchange system can select a suitable heat exchange mode according to different ambient temperatures or different driving conditions of the vehicle, and the connection between the interface and different heat exchange channels can be controlled by rotating the rotating valve core. The structure is simple and easy to operate.

在一些实施例中，转动阀芯包括中心轴以及挡板。挡板，沿中心轴朝向外壳方向延伸并将容纳腔分成多个互不连通的子腔体；其中，挡板在中心轴的带动下相对外壳运动，以将任一子腔体对应接口区。将中心轴作为转动轴能够驱动挡板旋转，以切换不同的换热模式，切换效率高。设置挡板将外壳容纳腔分成多个互不连通的子腔体，以实现对容纳腔空间的分割。并且，将挡板设置与中心轴上随着中心轴的转动而移动，以实现不同的子腔体与接口区的连通。上述的结构提高了设备的集成度以及操作效率。In some embodiments, the rotating valve core includes a central axis and a baffle. The baffle extends along the central axis toward the shell and divides the accommodating chamber into a plurality of sub-cavities that are not connected to each other; wherein the baffle moves relative to the shell driven by the central axis to correspond any sub-cavity to the interface area. Using the central axis as the rotating axis can drive the baffle to rotate to switch different heat exchange modes, and the switching efficiency is high. The baffle is set to divide the accommodating chamber of the shell into a plurality of sub-cavities that are not connected to each other to achieve the division of the accommodating chamber space. In addition, the baffle is set on the central axis to move with the rotation of the central axis to achieve the connection between different sub-cavities and the interface area. The above structure improves the integration and operating efficiency of the equipment.

在一些实施例中，子腔体中设有隔板，隔板将子腔体分成多个互不连通的子室。通过设置隔板，能够将子腔体分成多个相对封闭的子室，并且不同子腔体中隔板的设置位置均不相同，因此不同子腔体中子室的位置分布关系也不同。上述的结构，能够实现接口与换热管道之间不同的通断关系的控制，以达到换热模式的切换。In some embodiments, a partition is provided in the sub-cavity, and the partition divides the sub-cavity into a plurality of mutually unconnected sub-chambers. By providing the partition, the sub-cavity can be divided into a plurality of relatively closed sub-chambers, and the setting positions of the partitions in different sub-cavities are all different, so the position distribution relationship of the sub-chambers in different sub-cavities is also different. The above structure can realize the control of different on-off relationships between the interface and the heat exchange pipe to achieve the switching of the heat exchange mode.

在一些实施例中，每个子室与至多两个接口连通。与同一个子室连通的两个接口能够相互连通，上述的结构能够通过将两个接口与同一个子室连接实现相邻的两个换热流道之间的连通。In some embodiments, each subchamber is connected to at most two interfaces. Two interfaces connected to the same subchamber can be connected to each other. The above structure can achieve communication between two adjacent heat exchange channels by connecting the two interfaces to the same subchamber.

在一些实施例中，中心轴内还设有沿自身轴向延伸的中心流道，中心轴上还设有沿中心流道的径向贯穿的通孔以将子室与中心流道连通。在中心轴上设置中心流道，能够将间隔设置的两个子室进行连通，实现更多连通模式，提高接口与换热流道之间连通的灵活性，并满足热管理***连通的多样性要求。In some embodiments, a central flow channel extending along the central axis is further provided in the central axis, and a through hole penetrating along the radial direction of the central flow channel is further provided on the central axis to connect the sub-chamber with the central flow channel. The central flow channel is provided on the central axis, so that two sub-chambers arranged at intervals can be connected, more connection modes can be realized, the flexibility of the connection between the interface and the heat exchange flow channel can be improved, and the diversified requirements of the connection of the thermal management system can be met.

在一些实施例中，中心流道的横截面为圆形。上述的结构能够减小中心流道内介质的阻力，提高换热的效率。In some embodiments, the cross section of the central flow channel is circular. The above structure can reduce the resistance of the medium in the central flow channel and improve the efficiency of heat exchange.

在一些实施例中，中心流道的直径为R：15mm≤R≤20mm。当中心流道直径过小，流速达不到换热要求，造成换热效率过低。当中心流道直径过大，会增大中心轴的整体体积导致子室的体积过小介质流速降低，或者会导致中心轴的壁厚过低强度无法支撑。因此，设置合理的中心流道的直径能够在保证介质流速的同时，保证中心轴的结构强度以及子室的体积，保证换热***各流道的流速，保证换热***的换热效率以及运行的稳定性。In some embodiments, the diameter of the central flow channel is R: 15mm≤R≤20mm. When the diameter of the central flow channel is too small, the flow rate cannot meet the heat exchange requirements, resulting in low heat exchange efficiency. When the diameter of the central flow channel is too large, the overall volume of the central axis will be increased, resulting in the volume of the sub-chamber being too small and the medium flow rate being reduced, or the wall thickness of the central axis will be too low and the strength cannot be supported. Therefore, setting a reasonable diameter of the central flow channel can ensure the structural strength of the central axis and the volume of the sub-chamber while ensuring the medium flow rate, ensuring the flow rate of each flow channel of the heat exchange system, and ensuring the heat exchange efficiency and operation stability of the heat exchange system.

在一些实施例中，中心轴上设有多个通孔，每个通孔分别对应一个子室。通孔用于将子室的介质引入至中心流道，或者将中心流道介质引入至子室，上述的结构能够实现中心流道与子室之间的介质互通，实现多个子室之间的连通。In some embodiments, a plurality of through holes are provided on the central axis, each of which corresponds to a sub-chamber. The through holes are used to introduce the medium of the sub-chamber into the central flow channel, or to introduce the medium of the central flow channel into the sub-chamber. The above structure can realize the communication of the medium between the central flow channel and the sub-chamber, and realize the communication between the multiple sub-chambers.

在一些实施例中，子腔体包括第一子腔体，第一子腔体包括沿中心轴的轴向依次分布的第一子室、第二子室、第三子室以及第四子室，接口区包括沿中心轴的轴向分布的第一接口、第二接口、第三接口以及第四接口，第一接口对应第一子室设置，第四接口对应第四子室设置，中心轴对应第一子室以及第四子室分别设有第一通孔以及第二通孔，以将第一接口以及第四接口连通。In some embodiments, the sub-cavity includes a first sub-cavity, the first sub-cavity includes a first sub-chamber, a second sub-chamber, a third sub-chamber and a fourth sub-chamber distributed in sequence along the axial direction of the central axis, the interface area includes a first interface, a second interface, a third interface and a fourth interface distributed along the axial direction of the central axis, the first interface is arranged corresponding to the first sub-chamber, the fourth interface is arranged corresponding to the fourth sub-chamber, and the central axis is respectively provided with a first through hole and a second through hole corresponding to the first sub-chamber and the fourth sub-chamber to connect the first interface and the fourth interface.

通过将第一子室、第二子室、第三子室以及第四子室沿轴向分布，能够充分利用子腔体内的空间对子室进行排布，并且外壳上的第一接口、第二接口、第三接口以及第四接口与多个子室分别对应设置以实现连通，因此上述的结构能够便于外壳上接口的设置。通过设置第一通孔以及第二通孔，能够实现第一子室以及第四子室通过中心流道进行连通，因此第一接口以及第四接口通过第一子室以及第四子室实现了连通。上述的结构实现了两个间隔设置的子室之间的连通，提高了接口连通的多样性，提高了换热***的换热效率。By distributing the first subchamber, the second subchamber, the third subchamber and the fourth subchamber along the axial direction, the space in the subcavity can be fully utilized to arrange the subchambers, and the first interface, the second interface, the third interface and the fourth interface on the outer shell are respectively arranged corresponding to the multiple subchambers to achieve communication, so the above structure can facilitate the setting of the interface on the outer shell. By setting the first through hole and the second through hole, the first subchamber and the fourth subchamber can be connected through the central flow channel, so the first interface and the fourth interface are connected through the first subchamber and the fourth subchamber. The above structure realizes the connection between the two spaced subchambers, improves the diversity of interface connection, and improves the heat exchange efficiency of the heat exchange system.

在一些实施例中，外壳包括本体以及端盖。本体具有开口。端盖，与开口密封连接并共同限定出容纳腔。其中，中心轴的一端穿过端盖并突出于端盖的端面，中心轴用于与驱动机构连接。中心轴的一端可以设置花键，上述的结构能够便于中心轴与外部驱动机构连接并驱动挡板以及隔板移动，以实现不同的子腔体与接口区的连通，驱动机构可以是驱动电机，能够对旋转的角度以及转动的速度进行精确控制。上述的结构提高了多通阀切换的效率以及准确性，提高了设备的自动化程度。In some embodiments, the housing includes a body and an end cover. The body has an opening. The end cover is sealed and connected to the opening and together defines a accommodating cavity. One end of the central shaft passes through the end cover and protrudes from the end surface of the end cover, and the central shaft is used to connect with the driving mechanism. A spline can be set at one end of the central shaft. The above structure can facilitate the connection of the central shaft with the external driving mechanism and drive the baffle and the partition to move, so as to achieve the connection between different sub-cavities and the interface area. The driving mechanism can be a driving motor, which can accurately control the angle of rotation and the speed of rotation. The above structure improves the efficiency and accuracy of the multi-way valve switching and improves the degree of automation of the equipment.

在一些实施例中，外壳还包括密封件，密封件设于接口区朝向容纳腔的一侧。通过设置密封件降低相邻两个子腔体之间介质的串流的概率，提高挡板与外壳之间的密封性，保证多通阀切换过程中换热***运行的稳定性以及安全性。In some embodiments, the housing further comprises a seal, which is arranged on the side of the interface area facing the accommodating cavity. The seal is arranged to reduce the probability of cross-flow of the medium between two adjacent sub-cavities, improve the sealing between the baffle and the housing, and ensure the stability and safety of the heat exchange system during the switching process of the multi-way valve.

从市场形势的发展来看，新能源汽车热管理***趋于集成化设计，车辆中的热管理***需要根据季节以及电池的运行状况对车辆中的热能进行调整。车辆中热量的来源一般有电池、压缩机、热泵或者电驱***，热管理***需要根据环境温度或者驾驶员的需求，对上述几个热量来源进行交换，以实现能源利用最大化。各个热源之间通常通过设置不同的介质流道来进行热量传递，因此多个介质流道之间不同的连接模式即可实现不同的热源之间热量的交换。From the perspective of market development, the thermal management system of new energy vehicles tends to be integrated. The thermal management system in the vehicle needs to adjust the thermal energy in the vehicle according to the season and the operating status of the battery. The sources of heat in the vehicle are generally batteries, compressors, heat pumps or electric drive systems. The thermal management system needs to exchange the above heat sources according to the ambient temperature or the needs of the driver to maximize energy utilization. Heat is usually transferred between different heat sources by setting different medium flow channels. Therefore, different connection modes between multiple medium flow channels can realize heat exchange between different heat sources.

发明人研究发现，相关技术中通过设置多通阀实现不同的介质流道之间的连接与断开，以实现不同的热源之间热量的交换。但是大多数的多通阀的结构复杂，集成度不高，并且可切换的模式通常只有两种或三种，无法满足更多的切换模式的需求。The inventors have found that in the related art, a multi-way valve is provided to connect and disconnect different medium flow channels to achieve heat exchange between different heat sources.

In addition, by fixing the housing 10 to the mounting seat, the stability of the rotating valve core 20 during rotation can be ensured to improve the efficiency of the conversion process of the multi-way valve 100. The rotating valve core 20 is provided to form a plurality of sub-cavities 201, and the sub-cavities 201 can connect the plurality of interfaces 102 in different ways to achieve the connection mode of different heat exchange pipes in the heat exchange system.

如图3所示，在本申请的一些实施例中，转动阀芯20包括中心轴202以及挡板203。挡板203沿中心轴202朝向外壳10方向延伸并将容纳腔分成多个互不连通的子腔体201。其中，挡板203在中心轴202的带动下相对外壳10运动，以将任一子腔体201对应接口区101。挡板203的数量可以为多个。挡板203的一侧边连接于中心轴202，另一侧边与外壳10的内壁密封连接，以实现相邻两个子腔体201之间的相互密封。As shown in FIG3 , in some embodiments of the present application, the rotating valve core 20 includes a central axis 202 and a baffle 203. The baffle 203 extends along the central axis 202 toward the housing 10 and divides the accommodating cavity into a plurality of sub-cavities 201 that are not connected to each other. The baffle 203 moves relative to the housing 10 under the drive of the central axis 202 to correspond any sub-cavity 201 to the interface area 101. The number of baffles 203 can be multiple. One side of the baffle 203 is connected to the central axis 202, and the other side is sealed to the inner wall of the housing 10 to achieve mutual sealing between two adjacent sub-cavities 201.

The baffle 203 is set to divide the housing cavity of the shell 10 into a plurality of sub-cavities 201 that are not connected to each other, so as to achieve the division of the housing cavity space inside the shell 10. And the baffle 203 is set on the central axis 202 and moves with the rotation of the central axis 202 to achieve the communication between different sub-cavities 201 and the interface area 101. The above structure improves the integration and operation efficiency of the multi-way valve 100.

在本申请的一些实施例中，子腔体201中设有隔板204，隔板204将子腔体201分成多个互不连通的子室205。通过设置隔板204，能够将子腔体201分成多个相对封闭的子室205，并且不同子腔体201中隔板204的设置位置均不相同，因此不同子腔体201中子室205的位置分布关系也不同。上述的结构，能够实现接口102与换热管道之间不同的通断关系的控制，以达到换热模式的切换。In some embodiments of the present application, a partition 204 is provided in the sub-cavity 201, and the partition 204 divides the sub-cavity 201 into a plurality of mutually unconnected sub-chambers 205. By providing the partition 204, the sub-cavity 201 can be divided into a plurality of relatively closed sub-chambers 205, and the setting positions of the partitions 204 in different sub-cavities 201 are all different, so the position distribution relationship of the sub-chambers 205 in different sub-cavities 201 is also different. The above structure can realize the control of different on-off relationships between the interface 102 and the heat exchange pipe to achieve the switching of the heat exchange mode.

在本申请的一些实施例中，每个子室205与至多两个接口102连通。与同一个子室205连通的两个接口102能够相互连通，上述的结构能够通过将两个接口102与同一个子室205连接实现相邻的两个接口102之间的连通，从而使得与接口102连接的两个换热流道或者换热设备之间的连通。In some embodiments of the present application, each subchamber 205 is connected to at most two interfaces 102. Two interfaces 102 connected to the same subchamber 205 can be connected to each other, and the above structure can achieve communication between two adjacent interfaces 102 by connecting the two interfaces 102 to the same subchamber 205, thereby enabling communication between two heat exchange channels or heat exchange devices connected to the interfaces 102.

如图5以及图6所示，在本申请的一些实施例中，中心轴202内还设有中心流道206，中心轴202上还设有沿中心流道206的径向贯穿的通孔207以将子室205与中心流道206连通。在中心轴202上设置中心流道206，能够将间隔设置的两个子室205进行连通。上述的连接能变换更多接口的连通形式，实现更多换热设备的连通模式，提高接口102与换热流道之间连通的灵活性，并满足热管理***连通的多样性要求。As shown in FIG. 5 and FIG. 6, in some embodiments of the present application, a central flow channel 206 is further provided in the central shaft 202, and a through hole 207 is further provided on the central shaft 202 that penetrates radially along the central flow channel 206 to connect the subchamber 205 with the central flow channel 206. The central flow channel 206 is provided on the central shaft 202, so that the two subchambers 205 set at intervals can be connected. The above connection can change the connection form of more interfaces, realize the connection mode of more heat exchange equipment, improve the flexibility of the connection between the interface 102 and the heat exchange flow channel, and meet the diversity requirements of the connection of the thermal management system.

在本申请的一些实施例中，中心流道206的横截面为圆形。上述的结构能够提高中心流道206中换热介质的流速，减小中心流道206内换热介质的阻力，提高换热的效率。In some embodiments of the present application, the cross section of the central flow channel 206 is circular. The above structure can increase the flow rate of the heat exchange medium in the central flow channel 206, reduce the resistance of the heat exchange medium in the central flow channel 206, and improve the efficiency of heat exchange.

在本申请的一些实施例中，中心流道206的直径为R：15mm≤R≤20mm。示例性的，R可以为：15mm、18mm或20mm。当中心流道206直径过小，流速达不到换热要求，造成换热效率过低。当中心流道206直径过大，会增大中心轴202的直径，导致子室205的体积过小介质流速降低，或者会导致中心轴202的壁厚过低强度无法支撑。因此，设置合理的中心流道206的直径能够在保证介质流速的同时，保证中心轴202的结构强度以及子室205的体积，保证换热***各流道的流速，保证换热***的换热效率以及运行的稳定性。In some embodiments of the present application, the diameter of the central flow channel 206 is R: 15mm≤R≤20mm. Exemplarily, R can be: 15mm, 18mm or 20mm. When the diameter of the central flow channel 206 is too small, the flow rate cannot meet the heat exchange requirements, resulting in low heat exchange efficiency. When the diameter of the central flow channel 206 is too large, the diameter of the central axis 202 will be increased, resulting in the volume of the sub-chamber 205 being too small and the medium flow rate being reduced, or the wall thickness of the central axis 202 being too low and unable to support the strength. Therefore, setting a reasonable diameter of the central flow channel 206 can ensure the structural strength of the central axis 202 and the volume of the sub-chamber 205 while ensuring the medium flow rate, ensuring the flow rate of each flow channel of the heat exchange system, and ensuring the heat exchange efficiency and operation stability of the heat exchange system.

在本申请的一些实施例中，中心轴202上设有多个沿中心流道径向贯穿中心轴壁部的通孔207，每个通孔207分别对应一个子室205。通孔207用于将子室205的介质引入至中心流道206，或者将中心流道206介质引入至子室205，上述的结构能够实现中心流道206与子室205之间的换热介质互通，实现多个子室205之间的连通。In some embodiments of the present application, the central shaft 202 is provided with a plurality of through holes 207 penetrating the wall of the central shaft along the radial direction of the central flow channel, and each through hole 207 corresponds to a sub-chamber 205. The through hole 207 is used to introduce the medium of the sub-chamber 205 into the central flow channel 206, or to introduce the medium of the central flow channel 206 into the sub-chamber 205. The above structure can realize the heat exchange medium communication between the central flow channel 206 and the sub-chamber 205, and realize the communication between multiple sub-chambers 205.

The central axis 202 is provided with a first through hole 207A and a second through hole 207B corresponding to the first sub-chamber 208 and the fourth sub-chamber 211, respectively, so as to connect the first interface 103 and the fourth interface 106.

通过将第一子室208、第二子室209、第三子室210以及第四子室211沿轴向分布，能够充分利用子腔体201内的空间对子室进行排布，并且外壳10上的第一接口103、第二接口104、第三接口105以及第四接口106与多个子室分别对应设置以实现连通，因此上述的结构能够便于外壳10上接口的设置。By distributing the first subchamber 208, the second subchamber 209, the third subchamber 210 and the fourth subchamber 211 along the axial direction, the space in the subcavity 201 can be fully utilized to arrange the subchambers, and the first interface 103, the second interface 104, the third interface 105 and the fourth interface 106 on the outer shell 10 are respectively arranged corresponding to the multiple subchambers to achieve connectivity, so the above structure can facilitate the setting of the interfaces on the outer shell 10.

并且，通过设置第一通孔207以及第二通孔207，能够实现第一子室208以及第四子室211通过中心流道206进行连通，因此第一接口103以及第四接口106通过第一子室208以及第四子室211实现了连通。上述的结构实现了两个间隔设置的子室205之间的连通，丰富了接口102连通的多样性，提高了换热***的换热效率。Furthermore, by providing the first through hole 207 and the second through hole 207, the first subchamber 208 and the fourth subchamber 211 can be connected through the central flow channel 206, so the first interface 103 and the fourth interface 106 are connected through the first subchamber 208 and the fourth subchamber 211. The above structure realizes the connection between the two spaced subchambers 205, enriches the diversity of the connection of the interface 102, and improves the heat exchange efficiency of the heat exchange system.
