本发明的实施方式
在此处键入本发明的实施方式描述段落。本申请提出一种散热组件，被配置为对空调系统的电控组件进行散热。
目前，现有空调室外机的电控元件的降温方式是，通过金属散热器与空气对流来带走电控元件的热量，然而，在外界温度较高，且电控元件发热量较大时，金属散热器与外界高温空气之间的热量交换难以满足对电控元件的降温要求，而电控元件长期在高温条件下工作容易发生老化或电路故障等问题，从而降低了其使用可靠性。相关技术中，空调器电路板的散热通常采用铝基板散热器风冷散热，或者采用上下可铆合的双层铝基板，中间预留半圆形槽被配置为安装铜管，在铜管内通过低温的冷媒带走空调器电路板的热量。
需要说明的是，在空气中水汽含量不变，保持气压一定的情况下，空气冷却达到饱和时将出现凝露。从冷凝器出来的高温高压的冷媒进入电控中，对电控中的元件进行散热时，电控内温度通常不能低于环境的露点温度，如电控内温度低于环境露点温度，容易造成凝露风险，从而烧坏电控。
为了解决上述问题，参照图1和图2，在本申请一实施例中，该散热组件10包括：
冷媒换热管11，所述冷媒换热管11被配置为输入冷媒给电控组件20散热；
第一流量控制件12，设于所述冷媒换热管11上，被配置为控制流经所述冷媒换热管11的冷媒流量；
传感器组件13，被配置为检测环境露点温度T2及电控组件温度T1；
主控制器14，与所述传感器组件13连接，并根据所述传感器组件13检测的环境露点温度T2和电控组件温度T1调节控制所述第一流量控制件12。
本实施例中，第一流量控制件12可以为电子膨胀阀、节流阀等实现控制流量功能的控制件。
电控组件20可以设置为盒状，将电控板设置于电控盒中，电控板上通常设置有IGBT、MOS管等功率器件，在电控板的一侧还可以设置有散热器以对待功率器件进行散热。冷媒换热管11可以穿过电控盒设置，也即通过在电控盒内设置流道并在电控盒上设置与流道连通的进口和出口，从而可以将冷媒换热管11中的冷媒由基板的进口引入基板内的流道内，冷媒在电控盒的流道内流动并且与散热器进行热交换，吸收散热器上由功率器件产生并传递给散热器的热量，从而加快散热器的热量传递，进而加快电控板的散。冷媒换热管11可以设置为U型或者S型，以增大与散热器的散热面积。
传感器组件13设置有被配置为检测电控组件20和环境露点温度T2的温度传感器，其中，检测电控组件温度T1的传感器可以设置于电控板上，以靠近功率器件设置。检测环境露点温度T2的传感器可以设置于空调器的室外机上，在实际应用时，可以在空调室外机上设置干球温度计和湿度检测仪，从而即时计算出空气的露点温度。
主控制器14可以采用空调系统的室外机MCU来实现，或者，采用独立的MCU来实现，主控制器14可以采用单片机、DSP、FPGA等微处理器来实现。主控制器14中还集成有比较器、存储器、数据处理器，以及存储在所述存储器上并可在所述数据处理器上运行的算法、及其他软件程序和/或模块，通过调用、运行或执行存储在存储器内的算法、及其他软件程序和/或模块，来实现对第一流量控制件12的控制和调节。具体地，主控制器14根据检测到的环境露点温度T2和电控组件温度T1，确定第一流量控制件12的调节量，以控制输出冷媒流量，从而流经至电控组件20，并给电控组件20进行散热。也即通过控制第一流量控制件12的开度，可以控制冷媒管内的流量，进而控制电控盒内的散热温度，以确保控制电控盒内的温度始终高于环境的露点温度，降低凝露风险。同时，控制冷媒管内的流量还可以确保电控组件20散热充分，从而防止流经电控组件20的冷媒过少而使电控降温有限，导致电控工作在高温下而被损坏。
本申请散热组件10通过设置冷媒换热管11，以将接入的冷媒给电控组件20散热，以及设置传感器组件13，以检测环境露点温度T2及电控组件温度T1，并将检测的环境露点温度T2及电控组件温度T1输出至主控制器14。主控制器14根据传感器组件13检测的环境露点温度T2和电控组件温度T1调节控制设于所述冷媒换热管11上的第一流量控制件12流经电控组件20的冷媒流量，以使电控组件20散热充分。本申请解决了由于冷媒的不能节流，电控降温有限，导致调不能在高环境温度下长期工作的问题。通过控制冷媒管内流经电控组件20的流量，可以控制电控组件20的温度始终高于环境的露点温度，有利于降低凝露风险。本申请解决了冷媒管散热采用冷媒通过铜管直接与电控组件20换热，冷媒温度较低，容易造成凝露，从而烧坏电控的问题。
参照图1和图2，在一实施例中，当所述电控组件温度T1大于或等于第一预设温度时，所述主控制器14增大所述第一流量控制件12的开度；
当所述电控组件温度T1小于第一预设温度，且大于的第二预设温度时，所述主控制器14控制所述第一流量控制件12保持不变；
当所述电控组件温度T1小于或等于第二预设温度时，所述主控制器14减小所述第一流量控制件12的开度；其中，所述第一预设温度和第二预设温度均大于所述环境露点温度T2，且所述第一预设温度大于所述第二预设温度。
本实施例中，第一预设温度和第二预设温度可以设置为比露点温度略高的温度值，第一预设温度可以设置得比环境露点温度T2高2~4℃，第二预设温度可以设置得比环境温度高0.5~1.5℃，并且第一预设温度和第二预设温度随环境露点温度T2的变化而变化。本实施例以第一预设温度TX1=T2+2℃，第二预设温度TX2=T2+1℃为例进行说明。
当检测到T1≥T2+2时，则说明当前电控组件20的温度与环境露点温度T2相差较大，此时则可以增大第一流量控制件12的开度，以增大流经换热冷媒管的流量，从而提高对电控组件20的散热速率。
当检测到T2+1＜T1＜T2+2，则说明当前电控组件20的温度与环境露点温度T2相差较小，此时则可以维持第一流量控制件12的开度，以保持流经换热冷媒管的流量，从而维持对电控组件20的散热速率。
当检测到T2＜T1≤T2+1，则说明当前电控组件20的温度与环境露点温度T2比较接近，将达到电控组件20凝露的温度，此时则需要减小第一流量控制件12的开度，以减小流经换热冷媒管的流量，从而降低对电控组件20的散热速率。
参照图1和图2，进一步地，上述实施例中，所述散热组件10还包括旁路开关15，所述旁路开关15串联设置于所述冷媒管上；
当所述电控组件温度T1小于或等于所述环境露点温度T2时，所述主控制器14控制所述旁路开关15关闭，以断开所述冷媒换热管11的流路。
本实施例中，旁路开关15可采用电磁阀来实现，电磁阀基于主控制器14的控制而开/关，以控制流经电控组件20的冷媒散热旁路的通/断。具体地，当T1≤T2，则说明电控组件20的温度低于环境露点温度T2，电控组件20将出现凝露，此时则需要关断旁路开关15，从而切断流经电控组件20的冷媒散热旁路，将冷媒散热旁路断开，直至T1恢复至T2+2才恢复打开，以导通流经电控组件20的冷媒散热旁路，并给电控组件20提供散热的冷媒。
本实施例通过设置第一预设温度和第二预设温度，根据电控组件20的温度与第一预设温度、第二预设温度和环境露点温度T2的关系，调节控制第一流量控制件12的开度以及旁路开关15的开/关，有利于解决由于冷媒的不能节流，电控降温有限，导致调不能在高环境温度下长期工作的问题，以及冷媒管散热采用冷媒通过铜管直接与电控组件20换热，冷媒温度过低，容易造成凝露，从而烧坏电控，或者流经的冷媒过少，导致散热能力不足的问题。本实施在换热冷媒管上设置第一流量控制件12和旁路开关15，可以降低凝露风险，同时还防止旁路开关15频繁的启停。
参照图1和图2，在一实施例中，当所述电控组件温度T1小于安全温度时，所述主控制器14控制所述旁路开关15关闭，以断开所述冷媒换热管11的流路。
本实施例中，该安全温度为电控组件20的安全温度，在该安全温度下，电控组件20可以正常工作，并且不会因为温度过高而烧毁电控组件20。本实施例通过设置电控安全温度T3，当电控内温度低于安全温度，即当T1＜T3，则可以关闭旁路开关15，无需要冷媒管散热，从而减少冷媒因换热而导致能量的冷量有利于节约冷媒流量，以提高输出至蒸发器的冷媒换热量。
本申请还提出一种空调系统，所述空调系统包括电控组件20及如上所述的散热组件10；该散热组件10的详细结构可参照上述实施例，此处不再赘述；可以理解的是，由于在本申请空调系统中使用了上述散热组件10，因此，本申请空调系统的实施例包括上述散热组件10全部实施例的全部技术方案，且所达到的技术效果也完全相同，在此不再赘述。
其中，所述散热组件10的冷媒换热管11给所述电控组件20提供散热。
参照图1和图2，本实施例中，电控组件20设置有被配置为安装功率器件等电控元件的电控板，以及散热器，电控板安装在散热器上，散热器上设置有通孔。散热组件10设置有冷媒换热管11，冷媒换热管11穿过散热器，使冷媒通过冷媒换热管11与散热器热交换。散热组件10还设置有第一流量控制件12，第一流量控制件12设置在冷媒换热管11上，并分别位于散热器的一侧。通过控制冷媒管内流经电控组件20的流量，可以控制电控组件20的温度始终高于环境的露点温度，有利于降低凝露风险这可有效地避免电控组件20上出现凝露或结霜问题，从而保证空调系统的电路安全。
参照图1，在一实施例中，所述空调系统还包括：
依次串接并形成制冷回路的压缩机30、室外换热器40和室内换热器50，及被配置为控制冷媒流向的换向元件90；所述制冷回路具有冷媒高压侧输出端和冷媒低压侧输入端，其中，
所述散热组件10的冷媒换热管11串联设置于所述冷媒高压侧输出端和冷媒低压侧输入端之间；
或者，所述散热组件10的冷媒换热管11串联设置于所述冷媒高压侧输出端与压缩机30之间。
本实施例中，压缩机30、室外换热器40和室内换热器50通过冷媒管连通，压缩机30具有排气口和回气口；换向元件90为四通阀，被配置为根据冷却和供热模式选择地切换制冷剂通道，使得冷媒通过制冷剂管在室内机和室外机之间流动。该四通阀具有D端口、E端口、S端口和C端口，且D端口与排气口21连通，S端口与回气口22连通。根据工作模式的不同，在制冷模式下，室外换热器40作为冷凝器运行，室内换热器50作为蒸发器运行，在制热模式下其作为蒸发器运行，室内换热器50则作为冷凝器运行。室外换热器40的一端与E端口连通，室内换热器50的一端与C端口连通；室外换热器40和室内换热器50的另一端均可以设置为冷媒高压侧输出端和冷媒低压侧输入端，例如空调系统运行在制冷模式下时，室外换热器40的输出端则为冷媒高压侧输出端，此时室内换热器50则为冷媒低压侧输入端；而在制热模式下，则反之。其中，回路中，箭头所指的方向为冷媒的流向。
其中，散热组件10可以分别与室外换热器40的另一端和室内换热器50的另一端连通，在该实施例中，散热组件10与室外换热器40和室内换热器50形成的回路中，散热组件10相当于在高压侧和低压侧之间形成中间压力侧。电控组件20设置在第一流量控制件12的输出端，流经冷媒换热管11的冷媒经第一流量控制件12调节后，可起到降压的作用，以两相状态在的冷媒换热管11内流动。在另一实施例中，散热组件10则可以与室外换热器40和压缩机30连通，在该实施例中，散热组件10与室外换热器40和压缩机30形成的回路中，散热组件10相当于低压侧，流经冷媒换热管11的冷媒经第一流量控制件12调节后，并与电控组件20进行热交换后，转换为低压低温的气态冷媒，并回到压缩机30。上述两种方案的设置既可以有效提升电控的散热，又有利于降低电控凝露的风险。
参照图1，在一实施例中，所述空调系统还包括：
冷媒主流路60，串联设置于所述冷媒高压侧输出端和冷媒低压侧输入端之间；
第二流量控制件70，串接于所述冷媒主流路60上；所述第二流量控制件70被配置为控制流经所述冷媒主流路60的流量。
本实施例中，该冷媒主流路60为空调系统的主流路，由依次相连的压缩机30、冷凝器、第二流量控制件70和蒸发器形成，第二流量控制件70可以是毛细管、节流阀、电子膨胀阀中的任意一种。当空调系统以制冷模式运行时，压缩机30吸入从蒸发器出来的较低压力的气态冷媒，把压力较低的气态冷媒压缩成压力较高的气态冷媒，使气态冷媒的体积减小，压力升高，然后送入冷凝器，在冷凝器中放热冷凝成为压力较高的液态冷媒，经第二流量控制件70节流降压后，成为压力较低的液态冷媒进入蒸发器，在蒸发器中吸热蒸发成为压力较低的气态冷媒，并返回至压缩机30的回气口，从而完成制冷循环。
参照图1，在一实施例中，所述散热组件10还包括第三流量控制件80，串联设置于所述冷媒主流路60的输出端和所述冷媒低压侧输入端之间。
本实施例中，第三流量控制件80可以是毛细管、节流阀、电子膨胀阀中的任意一种，第三流量控制件80设置于第二流量控制件70和冷媒换热管11的公共端上，第三流量控制件80被配置为进一步地对经第一流量控制件12和第二流量控制件70输出的冷媒进行节流降压并输出至蒸发器，以使冷媒在蒸发器中吸热蒸发成为压力较低的气态冷媒，并返回至压缩机30的回气口，完成制冷循环。第二流量控制件70和第三流量控制件80可以自适应空调系统的压力，对冷媒进行调节，第二流量控制件70和第三流量控制件80可以降低电控组件20的凝露风险，同时还可以减少旁路开关15的启停频率。
本申请还提出一种空调系统的散热控制方法，所述空调系统具有散热组件，所述散热组件包括冷媒换热管和设置于所述冷媒换热管上的第一流量控制件；参照图3，所述空调系统的散热控制方法包括：

步骤S200、根据所述环境露点温度和电控组件温度调节控制所述第一流量控制件的开度。
其中，所述根据所述环境露点温度和电控组件温度调节控制所述第一流量控制件和旁路开关工作的步骤具体包括：
当所述电控组件温度小于第一预设温度，且大于的第二预设温度时，所述主控制器控制所述第一流量控制件保持不变；
当所述电控组件温度小于或等于第二预设温度时，所述主控制器减小所述第一流量控制件的开度；其中，所述第一预设温度和第二预设温度均大于所述环境露点温度，且所述第一预设温度大于所述第二预设温度；
当所述电控组件温度小于或等于所述环境露点温度时，所述主控制器控制所述旁路开关关闭，以断开所述冷媒换热管的流路。

以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的申请构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
