根据本申请的换热组件20适用于与车辆的电池30热交换，换热组件20包括：换热板21及连接件22。换热板21内部限定出换热流道2111a，换热流道2111a适于流通换热介质；连接件22连接换热板21的外缘，连接件22配置为与车身连接。在一些实 施例中，车辆包括车身和电池30，换热板21适于与电池30热交换，换热板21在与车身直接连接时，由于换热板21与车身之间形成有空隙，因此在换热板21与车身之间设置连接件22，如图2所示，连接件22环绕设置于换热板21的外缘，且适于将换热板21与车身连接，并将换热组件20与车身密封配合，此时电池30通过换热组件20与车身连接，以作为车身的一部分。
根据本申请的换热组件20通过设置连接件22以将换热板21与车身密封连接，避免换热板21与车身直接连接时产生的缝隙，确保车身的密封效果，并且，本申请的换热组件20通过环绕设置于换热板21外缘的连接件22将换热板21与车身直接连接，减少了上盖板结构，可以减少换热组件20及电池30在整车高度方向上的占用，并能降低整车重量，利于整车小型化、轻量化。
根据本申请的一些实施例，连接件22设于换热板21的朝向第一方向的第一侧面2113上，连接件22环绕换热板21设置且使得至少一部分换热板21外露，连接件22的朝向第一方向的第一表面不低于换热板21的最高端面，第一表面设有适于安装至车身的安装面。在一些实施例中，换热板21包括换热板本体，换热板本体在第一方向上具有背对彼此的第一侧面2113和第二侧面，换热板本体的第一侧面2113通过连接件22与车身连接，第二侧面与电池2连接；连接件22在第一方向上具有背对彼此的第一表面和第二表面，连接件22的第二表面连接于第一侧面2113并环绕设置于换热板本体的外缘，且使得换热板本体的中间部分露出，连接件22的第一表面不低于换热板本体第一侧面2113的最高端面，以使第一表面可以与车身连接，从而避免换热板本体与车身直接连接时产生的缝隙，确保车身的密封效果。
根据本申请的一些实施例，如图2所示，连接件22包括密封凸起221和密封板222，密封凸起221设于第一侧面2113且连接于换热板21的外缘，密封板222设于密封凸起221的背离第一表面的一侧；密封板222在第一表面的正投影完全覆盖密封凸起221的正投影，安装面设于密封板222。在一些实施例中，密封凸起221朝向换热板本体的表面即为所述第二表面，密封板222背离换热板本体的表面即为所述第一表面，密封凸起221连接于第一侧面2113并环绕连接于换热板21的外缘，密封板222连接于密封凸起221背离换热板本体的表面，以使连接件22可以与车身密封连接，从而将换热板本体与车身连接。
在一些实施例中，换热板本体的中间部分形成有换热流道2111a，密封凸起221设置于换热板本体外缘以缩小密封板222与换热板本体的间距，由于换热板本体外缘的部分面积较小，密封凸起221的面积也较小，直接将密封凸起221与车身密封配合会导致 密封凸起221与车身之间的连接不稳定，因此在密封凸起221和车身之间设置密封板222，至少部分密封板222可以覆盖于换热板本体的中间部分。密封板222适于将换热板21与车身连接，密封凸起221设置于密封板222和换热板本体之间以适于缩小密封板222与换热板本体的间距，以便换热板21通过连接件22与车身密封连接。
根据本申请的一些实施例，如图2所示，密封凸起221和密封板222为分体件，密封凸起221和密封板222可以通过整板激光裁剪或分段拼接后钎焊连接而成，使得连接件22整体结构简单，易于加工制造，可以降低换热组件20的生产成本。
根据本申请的一些实施例，如图1-图3所示，换热板21设有与换热流道2111a连通的进液管2114和出液管2115，密封凸起221设有避让进液管2114和出液管2115的避让槽221a，密封板222覆盖避让槽221a。可以理解的是，由于换热流道2111a具有流道进口和流道出口，为避让流道进口和流道出口，连接件22应使得具有流道进口和流道出口的凸起部2111外露，以避免影响换热介质进入或流出换热流道2111a，流道进口与进液管2114连通、流道出口与出液管2115连通，为避让进液管2114和出液管2115，在密封凸起221设置避让槽221a以使进液管2114和出液管2115外露，同时由于换热板21设置有进液管2114和出液管2115的部分也需与车身连接，因此令密封板222可以封盖密封凸起221设置有避让槽221a的部分，以确保换热板21与车身密封连接的效果。
根据本申请的一些实施例，如图2所示，换热板21包括流道板211及基板212。流道板211的一部分弯折以限定出凸起部2111；基板212设于流道板211且位于流道板211背离连接件22的一侧，基板212封堵凸起部2111以限定出换热流道2111a。在一些实施例中，流道板211和基板212在第一方向上设置并连接，第一侧面2113构造为流道板211背离基板212的表面，第二侧面构造为基板212背离流道板211的表面，凸起部2111朝向第一方向凸出并位于第一侧面2113，使得流道板211朝向基板212的表面形成有与凸起部2111一一对应的槽体，基板212适于封堵槽体以与流道板211限定出换热流道2111a。
在一些实施例中，流道板211和基板212通过钎焊工艺制焊接成型。
在一些实施例中，流道板211可通过模压或吹胀形成，具有成型快，重量轻的优点。
在一些实施例中，基板212可以直接裁切而成，基板212的第二侧面与电池30直接接触，可以保证足够的平面度。
在一些实施例中，换热组件20还包括分流器23，分流器23设置于换热流道2111a的流道进口和流道出口处。分流器23设置有凸台，基板212设置有适于与凸台配合的 定位孔，用于分流器23焊接定位，分流器23可通过机械加工、钎焊等工艺制作，凸台的高度与基板212相同或略大于基板212厚度。
根据本申请的一些实施例，至少部分换热板21形成有朝向第一方向凸出的凸起部2111，凸起部2111内部限定出换热流道2111a。在一些实施例中，换热板21的中间部分设置有朝向第一方向凸出的凸起部2111，由于凸起部2111的存在，使得换热板21与车身直接连接时与车身之间形成有多处空隙，难以实现完全密封，影响车辆密封效果，因此，在换热板21与车身之间设置连接件22，如图2所示，连接件22环绕于凸起部2111设置，且适于将换热板21与车身连接，并将换热组件20与车身密封配合，此时电池30通过换热组件20与车身连接，以作为车身的一部分。
在一些实施例中，换热板21可以包括换热板本体及凸出于换热板本体设置的凸起部2111，凸起部2111位于换热板本体的第一侧面2113，为使换热板21可以与电池30热交换且不至于对电池30造成磨损，应避免位于第一侧面2113的凸起部2111与电池30接触，因此令换热板本体的第二侧面正对电池30，此时换热板本体的第一侧面2113应与车身连接，但由于第一侧面2113还形成有凸起部2111，使得第一侧面2113无法与车身直接接触，因此在第一侧面2113设置连接件22，连接件22的第二表面连接于第一侧面2113并环绕凸起部2111设置，连接件22的第一表面不低于凸起部2111的最高端面，以使连接件22可以与车身密封连接，从而将换热板本体与车身连接，避免换热板本体与车身连接时因凸起部2111的存在而产生的缝隙，实现换热组件20与车身的密封连接。
根据本申请的一些实施例，如图5-图6所示，凸起部2111包括多个连通的凸起部分，至少一部分凸起部分间隔设置以限定出内陷凹槽2112。在一些实施例中，多个凸起部分所限定出的换热流道2111a彼此直接或间接连通，多个凸起部分中的至少部分间隔设置，以在第一侧面2113形成内陷凹槽2112，可以降低换热板21重量，以确保整车轻量化。在一些实施例中，一部分连接件22可以覆盖于多个凸起部分朝向车身的端部，此时所述一部分连接件22的第一表面高于多个凸起部分的最高端面，且所述一部分连接件22与车身密封连接，实现换热组件20与车身的密封连接。
根据本申请的一些实施例，如图6所示，一部分内陷凹槽2112内填充有连接件22的一部分。在一些实施例中，所述一部分连接件22形成有配合凸起2221，配合凸起2221适于在所述一部分连接件22覆盖于多个凸起部分朝向车身的端部时与内陷凹槽2112配合，以填充内陷凹槽2112，通过配合凸起2221与内陷凹槽2112配合，可以提升连接件22与换热板21的配合速度，从而提升整车装配速率，并且由于换热组件20与车 身配合后，换热板21和所述一部分连接件22位于车内部，位于乘客舱或驾驶舱的用户会踩踏换热板21和所述一部分连接件22朝向车内的表面，通过使连接件22的配合凸起2221与换热板21上的内陷凹槽2112配合，以使内陷凹槽2112的内壁对配合凸起2221起到支撑作用，可以提升换热组件20结构强度，避免换热板21或连接件22在用户踩踏后发生变形。
根据本申请的一些实施例，连接件22位于内陷凹槽2112上方的部分设有支撑件(未示出)，即所述一部分连接件22形成有支撑件，支撑件支撑于内陷凹槽2112以适于支撑连接件22，具体而言，通过使连接件22的支撑件与换热板21上的内陷凹槽2112配合，以使内陷凹槽2112的内壁对支撑件起到支撑作用，可以增强提升换热组件20结构强度。还可以是，支撑件设置于内陷凹槽2112且在第一方向延伸，以与所述一部分连接件22止抵，支撑件可以与凸起部分共同支撑所述一部分连接件22。
在一些实施例中，支撑件构造为翅片，以兼顾对所述一部分连接件22的支撑效果及换热板21对电池30的换热效果。
在一些实施例中，所述一部分连接件22即为密封板222。
在一些实施例中，当密封凸起221在第一方向上的尺寸不小于凸起部2111在第一方向上凸出于换热板21本体的高度时，密封板222整体与凸起部2111远离换热板21本体的端部止抵，此时密封板222与内陷凹槽2112之间设置有支撑件或配合凸起2221。
下面简单描述根据本申请的电池包1。
根据本申请的电池包1包括：框架、换热组件20及电池30，换热组件20为上述实施例中任意一项所述的换热组件20，换热组件20设于框架的顶部且与框架配合限定出容纳腔10a；电池30设于容纳腔10a内且与换热组件20热交换。在一些实施例中，换热组件20可以直接与框架连接，此时换热组件20可兼顾对电池30的换热功能及密封电池包1的上盖，可以减少电池包1的零件数量，并降低电池包1在整车高度方向上的空间占用。由于根据本申请的电池包1设置有上述实施例的换热组件20，因此该电池包1零件数量少且在整车高度方向上的占用少，电池包1更轻。
在一些实施例中，换热组件20可以通过焊接的方式与框架连接。
根据本申请的一些实施例，如图3所示，框架包括托盘11和底部换热件12，托盘11的底部敞开，底部换热件12设于框架以封堵框架的底部，底部换热件12与电池30热交换。在一些实施例中，在第一方向上，电池30的两侧分别设置有底部换热件12和换热组件20且底部换热件12及换热组件20与电池30之间均通过导热胶40连接，电池30周向上则设置有托盘11，此时底部换热件12可以封堵托盘11的底部以构造为 电池包1的底部，换热组件20可以封堵托盘11的顶部以构造为电池包1的顶部。底部换热件12和换热组件20均可与电池30进行热交换，且底部换热件12和换热组件20可选择地开启，以按照具体情况，实现对电池30的双层或单层换热，此时底部换热件12和换热组件20与电池30在第一方向上进行换热，可以让电池30的均温性更好。在一些实施例中，底部换热件12与换热板21构造相同。
下面简单描述根据本申请的车辆。
根据本申请的车辆包括上述实施例中任意一项所述的电池包1，由于根据本申请的车辆设置有上述实施例的电池包1，因此该车辆内部的密封效果更好，整车更轻、高度更低，易于小型化、轻量化。
综上所述，根据本申请的换热组件20通过设置连接件22以将换热板21与车身密封连接，避免换热板21与车身直接连接时产生的缝隙，确保车身的密封效果，并能减少换热组件20及电池30在整车高度方向上的占用，降低整车重量，利于整车小型化、轻量化。
