具体实施方式
下面结合图2至图4对本发明提供的技术方案进行更为详细的阐述，将本发明提供的任一技术手段进行替换或将本发明提供的任意两个或更多个技术手段或技术特征互相进行组合而得到的技术方案均应该在本发明的保护范围之内。
本发明实施例提供一种电器盒，优选应用于需要密闭的环境，即需要隔绝外部气体、液体的环境，比如作为空调等家用电器上的电器盒。参见图2和图3，该电器盒包括盒盖1和盒体2，盒盖1和盒体2配合，盒体2为金属盒体并具有容置腔9。盒体2外部设有散热鳍片3，散热鳍片3与盒体2为一体式结构，具体可铸造为一体。
盒体2容置腔9用于安装电路板4，电子元件安装在电路板4上。
上述技术方案，电器盒只有两个需装配在一起的独立部分：盒盖1和盒体2。盒体2与散热鳍片3为一体式结构，使得盒体2的散热性能大大提升。同时，一体式结构也能使得盒体2和散热鳍片3之间的密封效果好。
参见图2，盒体2具体可采用下述结构：盒体2具有容置腔9，容置腔9包括至少两个安装槽，各个安装槽的深度不相等，各安装槽对应于不同散热性能的电子元件。安装槽的深度满足使得安装槽的底面尽量贴紧电子元件，可以根据电子元件的具体类型、散热性能和结构设置相应的安装槽的深度，以扩大散热面积，提高散热效率。
进一步地，电器盒还包括电路板4，电路板4上安装有电子元件，电子元件包括功率半导体器件、电感或电容。其中，电路板4上的功率半导体器件对应深度较浅的安装槽，电感或电容对应深度较深的安装槽。
参见图3，散热鳍片3至少为两片，各散热鳍片分散设置在盒体2的底部，以尽量使得散热鳍片尽量布满盒体2的整个底部，以使得盒体2的散热均匀且迅速。
为使得整个电器盒的散热效果能满足不同电子元件的散热需求，深度较浅的安装槽下方的散热鳍片长于深度较深的安装槽下方的散热鳍片。各散热鳍片远离安装槽的一端尽量平齐，以便于安装。
为了实现平齐设置且长度不同，如图3所示，深度较浅的所述安装槽下方相对于深度较深的安装槽下方形成凹入结构。
进一步地，深度较浅的安装槽的底面为经过抛光处理过的底面，且该底面与位于该安装槽中的电子元件贴合。在深度较浅的安装槽中设置有功率半导体器件时，可将功率半导体器件与安装槽的底面贴合的面也经过抛光处理，以实现功率半导体器件良好散热。优选地，深度较深的安装槽中设置的电子元件与该安装槽的底面贴合或具有间隙。
此处，盒体2内部设计成不同高度(或称为深度)的安装槽，盒体的底面尽量贴近发热的电子元件。散热大的电子元件，比如功率半导体器件，即功率开关器件等扁平电子元件7与盒体的贴合面做抛光处理。功率半导体器件相应位置的安装槽较浅，盒体平台较高，接触面抛光，散热鳍片较长，这样可以实现功率半导体器件的良好散热。散热小的电子元件，比如储能电感电容、继电器等大体积电子元件6，其发热较小，对应的盒体2的安装槽较深，盒体平台较低，这些电子元件可以不与盒体2紧密贴合，但可以使电子元件到盒体2的距离很短。这样这些电子元件产生的热量可以通过空气介质传导到盒体2上，这样也可以保证长时间工作下也有足够的散热能力。上述设置方式，可以满足不同散热性能的电子元件的散热需求。
进一步地，盒盖1和盒体2之间可以采用多种形式实现密封连接，比如采用夹设密封圈的方式等，后文将给出优选的实现方式。需要说明的是，电器盒的盒盖1和盒体2之间采用密封连接与上文的盒体2与散热鳍片3为一体式结构可以单独采用，或是共同采用，优选为共同采用，这样既能提高电器盒的散热性能，也能保证电器盒的密封性能。
盒盖1和盒体2之间采用密封连接，盒体2与散热鳍片3为一体式结构，实现了电器盒与外部环境隔离，使得电器盒内外气液隔绝，排除燃爆隐患，达到真正的密封效果。
参见图3和图4，盒盖1和盒体2之间优选采用下述方式实现密封连接：盒体2边沿上设置有安装凹槽，盒盖1上对应设置有凸起。安装凹槽中容置有密封胶8，凸 起压紧在密封胶8上，使得凸起与密封胶8之间不留空隙。图4中上方的部分示意了盒盖1上的凸起未压在密封胶8上的情形；图4中下方的部分示意了盒盖1上的凸起压紧在密封胶8上的情形，图4中下方的部为图3中A处局部放大示意图。
安装时，先在安装凹槽中倒入融化状态的密封胶8，保证密封胶8与盒体2之间无间隙，然后将盒盖1上的凸起压在密封胶8上。密封胶8优选膨胀性能与盒体2相接近的材质，保证正常使用时密封胶8与盒体2紧密附着。
为使得盒盖1和盒体2之间连接可靠，盒盖1和盒体2之间还对应设置有可拆卸式连接结构。参见图3，此处以盒盖1外部和盒体2外部都设置有连接块为例，各连接块上都开设有螺孔，螺孔中安装有连接螺钉12，以此实现盒盖1和盒体2之间的可拆卸式固定。通过可拆卸式连接结构可以进一步压紧密封胶8。可拆卸式连接结构的数量可以为多个，以设置两个为例，两个可拆卸连接结构分别位于盒体1的两端。
参见图2，盒体2的侧壁上开设有密封线缆接头安装孔10，密封线缆接头安装孔10用于安装密封线缆接头11，通过密封线缆接头11实现电器盒与外部部件的电气连接。
本发明实施例还提供一种家用电器，家用电器优选为空调或具有类似结构和使用性能的产品。该家用电器包括本发明任一技术方案所提供的电器盒，电器盒内安装有电路板，电路板上安装有电子元件。
盒体2可直接接大地，电器盒的安装槽中的电路板4与盒体2之间采用金属螺钉5连接。具体地，是将电路板4需要接地的部分与盒体2之间采用金属螺钉5连接，以实现电路板4的固定和接地。
本发明实施例还提供一种具有易燃易爆制冷剂的空调器，该空调器包括本发明任一技术方案所提供的电器盒。
如果本文中使用了“第一”、“第二”等词语来限定零部件的话，本领域技术人员应该知晓：“第一”、“第二”的使用仅仅是为了便于描述上对零部件进行区别如没有另行声明外，上述词语并没有特殊的含义。
最后应当说明的是:以上实施例仅用以说明本发明的技术方案而非对其限制；尽管参照较佳实施例对本发明进行了详细的说明，所属领域的普通技术人员应当理解：依 然可以对本发明的具体实施方式进行修改或者对部分技术特征进行等同替换；而不脱离本发明技术方案的精神，其均应涵盖在本发明请求保护的技术方案范围当中。
