技术领域
本申请涉及能源技术领域，尤其涉及一种充电设备和充电系统。
背景技术
随着电动车辆的广泛普及，业界对充电设备(如充电桩)的需求也越来越大。充电设备中通常会包括多种不同类型的电气元件，一些电子器件在工作时会产生大量的热，为了保证充电设备处于正常的工作温度范围内，通常需要对充电设备中的一些电子器件进行散热。目前，通常采用风冷的方式对电子器件进行散热。在风冷方式中，一般采用风扇产生气流，使气流快速经过发热器件的表面，从而带走热量。但是，这种方式容易使灰尘等杂质积累在电子器件的表面，会影响电子器件的可靠性和使用寿命。另外，风扇在高速运转时产生的噪音也比较大，影响用户的充电体验。
发明内容
本申请提供了一种结构简单，散热效率好的充电设备和充电系统。
第一方面，本申请提供了一种充电设备，包括弹性导热件和至少两个堆叠设置的功率组件。功率组件包括外壳、液冷板和电路板组件，外壳和液冷板围成容纳腔，电路板组件设置在容纳腔内并与外壳和液冷板均导热连接。每个功率组件的液冷板具有第一接触面，外壳具有第二接触面，第一接触面与第二接触面相背离。其中，在相邻的两个功率组件中，其中一个功率组件的第一接触面与另一个功率组件的第二接触面相向设置，弹性导热件位于第一接触面和第二接触面之间，并与第一接触面和第二接触面分别弹性抵接。
在本申请提供的充电设备中，功率组件中采用液冷板进行散热，外壳也液冷板能够围成用于容纳电路板组件的空间，能够提升电路板组件的密闭性，防止外界的灰尘、水汽等杂质对电路板组件产生影响，能提升充电设备的工作安全性和可靠性。另外，弹性导热件与功率组件导热接触，使得功率组件的热量能够通过弹性导热件进行散发，从而能提升功率组件的散热性能。由于液冷板的散热性能通常会大于外壳的散热性能，因此，在相邻的两个功率组件中，其中一个的功率组件的外壳的热量能够通过弹性导热件传递至另一个功率组件的液冷板，因此，有利于提升充电设备的整体散热性能。
在具体设置时，电路板组件中可以包括电路板和设置在电路板上的电子器件。其中，电路板包括相背离的第一板面和第二板面，电子器件位于第一板面。
在具体设置时，电子器件可以与液冷板导热连接，从而能够使液冷板对电子器件进行较高效率的散热。第二板面可以与外壳导热连接。
在一种示例中，弹性导热件可以为波浪形的片体。弹性导热件具有结构简单、便于制作，并且具有较好的弹性。
另外，弹性导热件与第一接触面之间具有第一风道，弹性导热件与第一接触面之间具有第二风道。流经第一风道和第二风道的空气可以快速带走第一接触面、第二接触面和弹性导热件的热量，有利于提升充电设备的散热性能。
在一种示例中，弹性导热件朝向所述第一接触面的表面具有至少一个与第一接触面相抵的第三接触部，且第三接触部可以为平面，从而有利于提升第一接触面与弹性导热件之间的接触面积。
在一种示例中，弹性导热件朝向所述第二接触面的表面具有至少一个与第二接触面相抵的第四接触部，且第四接触部为平面，从而有利于提升第二接触面与弹性导热件之间的接触面积。
在一种示例中，弹性导热件的材质包括形状记忆合金。其中，弹性导热件用于当温度上升时，趋于增加与第一接触面或第二接触面之间的接触面积。使得在第一接触面的温度较高时，能够增加弹性导热件与第一接触面或第二接触面之间的接触面积，有利于提升对外壳的散热效果。
在一种示例中，充电设备还可以包括机箱，功率组件安装在机箱内，弹性导热件可拆卸的安装在机箱内，从而具有较高的使用灵活性。
在一种示例中，弹性导热件与外壳或液冷板固定连接，从而能够提升在对充电设备进行装配时的便利性。
在一种示例中，充电设备包括托盘，弹性导热件与托盘固定连接。其中，功率组件可以通过托盘固定在机箱内，并且，可同时实现与导热件之间的导热接触，能有效提升装配时的便利性。
在一种示例中，充电设备还可以包括散热器，散热器通过液冷管路与液冷板连接，用于对液冷板进行散热。
第二方面，本申请还提供了一种充电系统，包括充电终端和上述任一种充电设备，充电设备具有输出端口，充电终端与输出端口连接。经充电设备处理后的电能可以提供给充电终端，以便于向受电设备(如车辆)补充电能。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
为了方便理解本申请实施例提供的充电设备，下面首先介绍一下其应用场景。
如图1所示，在本申请提供的一种示例中，充电设备10可以应用在对电动车辆20进行充电的场景中。具体的，充电设备10具体可以是充电桩，充电设备10可以安装在停车位附近。在实际应用中，充电设备10的输入端可以与电网30进行连接，充电设备10的输出端可以通过一段线缆40与充电枪50进行连接，以便于对车辆20进行充电。其中，电网30中的电能可以是工业用电(如交流电压为380V)，也可以是民用电(如交流电压为22V)等。
在实际应用中，充电设备10可具备过载保护、功率转换等功能。在充电设备10中通常会包括晶体管、变压器、电感、电容或继电器等电子器件。其中，一些电子器件在正常工作时会产生热量，为了使得充电设备10处于正常的工作温度范围内，需要对电子器件进行散热。
在目前的充电设备中，一般采用风冷的方式对充电设备进行散热。在采用风冷方式的充电设备中，一般采用风扇产生气流，使气流快速经过电子器件的表面，从而带走热量。但是，这种方式容易使灰尘等杂质积累在电子器件的表面，会影响电子器件的可靠性和使用寿命。另外，风扇在高速运转时产生的噪音也比较大，影响用户的充电体验。
有鉴于此，本申请实施例提供了一种结构简单，成本较低，能实现较高防护等级的充电设备10以及应用该充电设备10的充电系统。
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图和具体实施例对本申请作进一步地详细描述。
如图2所示，在本申请提供的一种示例中，充电设备10可以包括第一功率组件11a、第二功率组件11b和弹性导热件12。弹性导热件12位于第一功率组件11a和第二功率组件11b之间，并与第一功率组件11a和第二功率组件11b导热接触。其中，在一些情况下，第一功率组件11a的热量可以通过弹性导热件12和第二功率组件11b进行散发，从而能够提升充电设备10的散热效率。相应的，在一些情 况下，第二功率组件11b的热量可以通过弹性导热件12和第一功率组件11a进行散发，从而能够提升充电设备10的散热效率。概括来说，弹性导热件12不仅能够对第一功率组件11a和第二功率组件11b所产生的热量进行有效散发，另外，还能够实现第一功率组件11a与第二功率组件11b之间热量的传递，从而能够有效提升充电设备10的散热性能。
另外，在本申请提供的示例中，第一功率组件11a和第二功率组件11b均采用液冷的散热方式，具有散热效率高、可靠性好、噪声低等优势，有利于保证电子器件的密闭性，能提升充电设备10的工作稳定性和使用寿命。
具体来说，第一功率组件11a包括第一外壳111a、第一液冷板112a和第一电路板组件113a。第一外壳111a和第一液冷板112a围成容纳腔(图中未示出)，第一电路板组件113a设置在容纳腔内并与第一外壳111a和第一液冷板112a导热连接。第一液冷板112a内具有管路1121a，冷却介质可以在管路1121a中流通，从而带走第一液冷板112a的热量。第二功率组件11b包括第二外壳111b、第二液冷板112b和第二电路板组件113b。第二外壳111b和第二液冷板112b围成容纳腔(图中未示出)，第二电路板组件113b设置在容纳腔内并与第二外壳111b和第二液冷板112b导热连接。第二液冷板112b内具有管路1121b，冷却介质可以在管路1121b中流通，从而带走第二液冷板112b的热量。
在本申请提供的示例中，第一功率组件11a和第二功率组件11b的结构基本相同，下面将以第一功率组件11a为例进行具体说明。
第一电路板组件113a位于第一外壳111a和第一液冷板112a围成的空间内，从而有利于保证第一电路板组件113a的密闭性，能防止外界的灰尘、水汽等杂质对第一电路板组件113a造成腐蚀。
另外，第一电路板组件113a与第一液冷板112a和第一外壳111a导热连接，第一电路板组件113a产生的热量能够通过第一液冷板112a和第一外壳111a进行散发，能够提升第一功率组件11a的散热效率。
具体的，在本申请提供的示例中，第一电路板组件113a包括第一电路板1131a和多个(图中示出有四个)电子器件1132a。其中，第一电路板1131a具有第一板面11311a和第二板面11312a，且第一板面11311a和第二板面11312a为第一电路板1131a的相背离的两个板面，多个电子器件1132a均设置在第一板面11311a，并通过导热硅脂13等导热性较好的材料与液冷板112a导热连接。第一电路板1131a的第一板面11311a通过导热硅脂14等导热性较好的材料与第一外壳111a导热连接。
在本申请提供的示例中，将电子器件1132a均设置在第一电路板1131a的第一板面11311a，在进行制作时，有利于提升第一电路板组件113a的制作效率。例如，可以采用表贴等工艺将电子器件1132a均设置在第一电路板1131a的第一板面11311a。或者，可以理解的是，若将多个电子器件1132a分别设置在第一电路板1131a的第一板面11311a和第二板面11312a时，需要对第一电路板1131a进行翻转，或者需要进行二次焊接等操作，因此，会增加制作流程和工艺，不利于提升制作效率。
另外，在对第一功率组件11a进行装配时，可以使第一电路板1131a的第一板面11311a朝向第一液冷板112a设置，有利于实现多个电子器件1132a与第一液冷板112a之间的导热连接。
在实际应用中，在第一电路板1131a中有电流流通时，会产生热量，因此，第一电路板1131a也存在散热需求。
在本申请提供的示例中，由于第一电路板1131a的第二板面11312a朝向第一外壳111a设置，因此，有利于实现第一电路板1131a与第一外壳111a之间的导热连接。
可以理解的是，在实际应用中，电子器件1132a的发热量通常会大于第一电路板1131a的发热量；第一液冷板112a的散热效率大于第一外壳111a的散热效率，因此，可以将第一电路板1131a与第一外壳111a进行导热连接，使得第一电路板1131a能够通过第一外壳111a进行散热。将电子器件1132a与第一液冷板112a进行导热连接，使得电子器件1132a能够通过第一液冷板112a进行散热。
其中，第一外壳111a主要依靠材料本身的热传递进行散热，可以由钢、铜或铝等热传导性较好的材料制作，第一外壳111a具有便于制作、成本较低、可靠性较高的优势。另外，在进行制作时，也比较容易制备形状比较复杂结构。
对于第一液冷板112a，由于其内部具有供冷却介质进行流通的通道，在实际应用中，不利于制备比较复杂的形状，否则会出现可靠性低、成本明显增高等问题。
目前，随着充电设备10功率的不断提升，第一电路板1131a的散热需求也在不断提高。在实际应用中，若将第一外壳111a更改为液冷的结构形式(如与第一液冷板112a相似的结构)，会明显增加充 电设备10的成本。或者，若将第一液冷板112a中的液冷结构延伸至第一外壳111a内，也会增加冷却管路1121a的改造成本，同时，也会增加冷却管路1121a泄露的风险。
在本申请提供的示例中，将第一功率组件11a和第二功率组件11b进行堆叠设置后，通过弹性导热件12可以提升对第一电路板1131a的散热效果。
具体来说，第一功率组件11a的第一液冷板112a具有第一接触面101a，第一外壳111a具有第二接触面102a。第二功率组件11b的第二液冷板112b具有第一接触面101b，第二外壳111b具有第二接触面102b。第一接触面101b和第二接触面102a相向设置，弹性导热件12位于第一接触面101b和第二接触面102a之间，并与第一接触面101b和第二接触面102a弹性抵接。第一电路板1131a产生的热量传递至第一外壳111a后，可以通过弹性导热件12传递至第二液冷板112b。即第二功率组件11b的第二液冷板112b能够对第一功率组件11a的第一电路板1131a进行散热，从而能够明显提升对第一电路板1131a的散热效果。
或者可以理解的是，在本申请提供的示例中，每个功率组件的第一接触面和第二接触面为相背离设置的两个表面。
例如，在第一功率组件11a中，第一接触面101a与第二接触面102a相背离。将多个功率组件进行堆叠设置时，每个功率组件可以按照基本相同的空间姿态进行依次堆叠。因此，在相邻的两个功率组件中，其中一个功率组件的第一接触面能够与另一个功率组件的第二接触面相向设置。
在具体应用时，弹性导热件12的结构形状可以是多样的。
例如，如图2所示，在本申请提供的一种示例中，弹性导热件12为波浪形的板状结构。具体来说，弹性导热件12的波峰和波谷均为弧面。
在自然状态下，弹性导热件12的波峰与波谷之间的高度差大于第一接触面101b与第二接触面102a之间的距离。将弹性导热件12设置在第一接触面101b与第二接触面102a之间后，弹性导热件12会受到第一接触面101b和第二接触面102a的挤压力，从而与第一接触面101b和第二接触面102a弹性抵接。另外，弹性导热件12受到挤压后，会产生弹性形变，使得弹性导热件12与第一接触面101b之间的接触面积会得到增加、弹性导热件12与第二接触面102a之间的接触面积会得到增加，有利于保证弹性导热件12与第一接触面101b和第二接触面102a的接触效果。
另外，在本申请提供的示例中，在弹性导热件12与第一接触面101b之间会形成第一风道121，在弹性导热件12与第二接触面102a之间会形成第二风道122。当有空气流经第一风道121时，会带走弹性导热件12和第一接触面101b的热量。相应的，当有空气流经第二风道122时，会带走弹性导热件12和第二接触面102a的热量，有利于提升充电设备10的散热效率。
在实际应用中，可以在充电设备10中设置风扇，从而可以提升流经第一风道121或第二风道122的空气的流动速度。
概括来说，将弹性导热件12设置为波浪形后，不仅能够保证弹性导热件12与第一接触面101b和第二接触面102a之间的弹性抵接，还可以使得弹性导热件12与第一接触面101b之间形成第一风道121、使弹性导热件12与第二接触面102a之间形成第二风道122，从而有利于提升充电设备10的散热性能。
可以理解的是，在其他的示例中，弹性导热件12也可以是其他的形状。
例如，请结合参阅图2和图3，在本申请提供的另一种示例中，弹性导热件12朝向所述第一接触面的表面与第一接触面101b具有至少一个与所述第一接触面相抵的第三接触部120a，所述第三接触部120a为平面。弹性导热件12朝向第二接触面102a的表面具有至少一个与第二接触面102a相抵的第四接触部120b，第四接触面120b也为平面。在图3中提供的示例中，第三接触部120a和第四接触部120b的数量均为6个，可以理解的是，在其他的示例中，第三接触部120a和第四接触部120b的数量也可以是一个、两个或者更多个，本申请对此不作限制。
具体来说，由于第一接触面101b为平面，因此，将弹性导热件12与第一接触面101b相抵的第三接触部120a设置为平面后，可以提升弹性导热件12与第一接触面101b之间的接触面积，有利于提升弹性导热件12与第一外壳111a之间的热交换效率。相应的，由于第二接触面102a为平面，因此，将弹性导热件12与第二接触面102a相抵的第四接触面120b设置为平面后，可以提升弹性导热件12与第二接触面102a之间的接触面积，有利于提升弹性导热件12与第一液冷板112a之间的热交换效率。
当然，在实际应用中，第一接触面101b或第二接触面102a也可以是曲面，弹性导热件12与第一接触面101b或第二接触面102a相接触的表面也可以是曲面，在此不作赘述。
在具体应用时，弹性导热件12可以采用铜、铝及其合金等具有较高导热性的材料进行中制作。
或者，弹性导热件12的材质也包括形状记忆合金。当弹性导热件12的温度上升时，趋于增加与第一接触面101b或第二接触面102a之间的接触面积，从而可以提升弹性导热件12与第一接触面101b或第二接触面102a之间的接触面积。
具体来说，在实际应用中，弹性导热件12由于与第一接触面101b和第二接触面102a进行接触，因此，当第一外壳111a的温度较高时，需要对第一外壳111a进行较高效率的降温。因此，当第一外壳111a的高温传递至弹性导热件12后，会使弹性导热件12产生预定的形变，并且，这种形变可以提升弹性导热件12与第一接触面101b和第二接触面102a之间的接触面积，从而能够提升第一接触面101b和第二接触面102a之间的换热效率。
例如，在温度较低时，弹性导热件12的形状可以是类似于图2中所示出的形状。在温度较高时，弹性导热件12的形状可以是类似于图3中所示的形状。
当然，在其他的示例中，也可以根据不同需求对弹性导热件12的形状与温度的关系合理设置，在此不作赘述。
另外，在其他的示例中，弹性导热件12也可以是具有可弹性压缩特性的导热垫等结构，在此不作赘述。
在实际应用中，弹性导热件12可以是独立的结构件，或者，也可以是功率组件的组成部分。
例如，如图4所示，弹性导热件12可以与第一外壳111a固定连接。
或者，如图5所示，弹性导热件12可以与第二液冷板112b固定连接。
可以理解的是，在上述的实施例中，以充电设备10中包括两个功率组件为例进行的具体说明，在实际应用中，充电设备10中可以包括三个或者三个以上的功率组件。
例如，如图6所示，在本申请提供的一种示例中，充电设备10还包括机箱15，多个功率组件11依次堆叠设置在机箱15内。
在进行安装时，可以将功率组件11安装到位后，将弹性导热件12插入相邻的两个功率组件11之间的缝隙内。或者，也可以将功率组件11和弹性导热件12进行依次安装。
如图7所示，在一些示例中，机箱15中还可以包括托盘16等抽屉式结构，功率组件11可以通过托盘16等结构安装在机箱15中，以提升安装和维护时的便利性。其中，托盘16与机箱15之间可以通过滑轨等目前常用的结构进行连接，本申请对此不作限定。
另外，如图8所示，在一些示例中，弹性导热件12可以与托盘16固定连接。请结合参阅图6和图8。位于托盘16两侧的功率组件11安装在箱体15内后，便可实现功率组件11与弹性导热件12的导热接触，从而具有较高的安装便利性。
另外，如图6所示，在本申请提供的一种示例中，充电设备10还包括散热器17，散热器17可以通过管路与功率组件11中的液冷板连接，冷却介质可以在散热器17和液冷板之间进行循环流通，使得散热器17能够对液冷板进行降温。
在具体设置时，风扇17可以设置在散热器17的顶部，用于加速流经散热器17的空气的流动速度，从而提升散热器17的散热效率。
另外，在本申请提供的示例中，机箱15内还具有隔板151，隔板151将机箱15的内部空间分隔为配电区和用于安装功率组件11的区域。配电设备19可以设置在配电区，在对配电设备19进行设置时，配电设备19中可以包括目前常用的断路器、过载保护电路等。配电设备19可以安装在机箱15的内壁，或者，也可以将配电设备19集成设置在一个柜体，本申请对此不作限定。
可以理解的是，在具体应用时，配电设备19中所包含的器件的类型和数量可以根据实际需求进行灵活调整，本申请对此不作限定。
另外，如图9所示，本申请实施例还提供了一种充电系统，包括充电终端60和充电设备10，充电终端60通过一段线缆与充电设备10的输出端连接。在具体应用时，充电设备10可以将电网中的交流电进行变频等处理，或者，可以经交流电转变为直流电后提供给充电终端60.充电终端60可以与受电设备(如车辆)进行连接，从而可以向受电设备补充电能。其中，充电终端60可以是充电枪等形态。另外，一个充电设备10可以与一个充电终端60连接，或者，也可以与多个充电终端60连接，本申请对充电终端60的设置数量不作限制。
在具体设置时，充电设备10可以安装在地面上，也可以安装在墙面等位置。本申请对充电设备10 的具体安装位置和形态不作限制。
在本申请的各个实施例中，如果没有特殊说明以及逻辑冲突，不同的实施例之间的术语和/或描述具有一致性、且可以相互引用，不同的实施例中的技术特征根据其内在的逻辑关系可以组合形成新的实施例。
