空调器通常设置电控板,用于控制压缩机、风机等部件的工作,使制冷系统能够稳定运行,应用于分体式空调器、整体式空调器等。以空调室外机的电控板为示例,电控板上通常设置有主控制模块、智能功率模块(Intelligent Power Module,IPM)、整流桥、电源模块等功能模块,这些功能模块的电路器件布局较为分散,排布在印刷电路板的各个部位,使得电控板的体积较大,不利于安装,与电控板小型化设计方向背道而驰;而且器件分散部件会增加接线的难度,装配过程中连线插接极为不便,耗费工时,影响生产效率。
本公开的实施例通过合理设计各个模块电路的布局,使各个模块电路安装更加紧凑,减小器件的占用面积,从而有效减小电控板的整体体积,安装灵活性更高,有利于提高空调室外机的装配效率。
参考图1至图5描述本公开实施例的电控板1000,该电控板1000适用于空调器,具体应用于空调室外机,下面以具体示例对电控板1000进行说明。
参照图1所示,实施例的电控板1000包括基板100,该基板100为印制电路板,基板 100大致呈长方形,在基板100上设置有主控制电路200、整流与逆变电路300、电源输入电路400和功能接口电路500,各个电路均由相应的器件连接组成,图1所示,在基板100上划分为四个区域,主控制电路200、整流与逆变电路300、电源输入电路400和功能接口电路500按区域排布在基板100的正面,组成电控板1000的整体控制电路。
其中,主控制电路200包括控制芯片210和与控制芯片210连接的被动元器件,主要用于采集相关的数据并控制风机、压缩机等部件的运行。整流与逆变电路300包括整流电路和逆变电路两部分,整流电路能够将输入的交流电转化为直流电,逆变电路能够将直流电转化为三相电输出,用于驱动压缩机工作。电源输入电路400用于空调室外机电源的输入,整流电路将输入的交流电转化为直流电,从而能够向控制芯片210及相关模块供电,也可输出对外部部件进行供电。功能接口电路500包括插座520和与插座520连接的外围电路,插座520用于相关负载接口的输出。
参照图1所示,在基板100的正面划分为第一安装区110、第二安装区120、第三安装区130和第四安装区140,主控制电路200安装在第一安装区110,整流与逆变电路300安装在第二安装区120,电源输入电路400安装在第三安装区130,功能接口电路500安装在第四安装区140,使得各个电路按区域进行布局,不同电路的器件相应地连接在基板100上不同安装区所在的位置。
以主控制电路200为示例,主控制电路200包括控制芯片210和外围的被动元器件,控制芯片210和被动元器件均焊接在基板100上第一安装区110所对应的位置,被动元器件通过基板100上布置的铜质线路与控制芯片210的引脚进行连接,各个被动元器件与控制芯片210之间相对位置可根据第一安装区110的区域大小进行排列,例如,被动元器件包括电阻、电容等,被动元器件可以环绕控制芯片210进行排布,也可以将被动元器件集中排布在控制芯片210的一侧。
参照图1所示,图1为电控板1000的正面结构示意图,基板100的长度方向为图1中所示的左右方向,基板100的宽度方向为图1中所示的上下方向,其中,基板100沿长度方向包括第一侧边和第二侧边,第一侧边为基板100的左侧边,第二侧边为基板100的右侧边,第一安装区110和第二安装区120设置靠近左侧边,第三安装区130和第四安装区140设置靠近右侧边,沿基板100的宽度方向,第一安装区110和第二安装区120自上至下依次排列,第三安装区130和第四安装区140自下至上依次排列。
需要说明的是,第一安装区110和第二安装区120靠近基板100的左侧边应理解为第一安装区110和第二安装区120位于基板100沿左右方向的左侧,第一安装区110和第二安装区120的左侧边可以与基板100的左侧边接近或重合。同理,第三安装区130和第四 安装区140靠近右侧边,理解为第三安装区130和第四安装区140位于基板100沿左右方向的右侧,第三安装区130和第四安装区140的右侧边可以与基板100的右侧边接近或重合。
考虑到不同电路的器件形式、数量等均不相同,根据不同电路要求划分不同安装区的区域大小,各个安装区在基板100上所占的面积并不一致。具体来说,实施例中第一安装区110位于基板100的左上角位置,第二安装区120位于基板100的左下角位置,第三安装区130位于基板100的右下角位置,第四安装区140位于基板100的右上角位置,各个安装区大致呈长方形,各个电路的器件均能够充分排布在相应的安装区内,四个安装区所占的面积刚好等于基板100的面积,使得整体电路安装紧凑。
需要说明的是,各个安装区之间不具有物理分隔界限,主控制电路200、整流与逆变电路300、电源输入电路400和功能接口电路500根据所在安装区域的大小进行合理排布,可以将各个电路中的主要功能器件所在的区域按一定的尺寸范围定义为其所对应的安装区,例如,在主控制电路200中,控制芯片210为主要功能器件,控制芯片210与外围的被动元器件组成电路,相邻器件之间具有一定的安全距离要求,根据上述安全距离要求进行排布,可以计算得到主控制电路200所需占用的面积,从而可对应设置第一安装区110的尺寸。为便于理解,以图1所示实施例为示例,图1中虚线位置可理解为各个安装区的分界线,分界线根据各个电路的分布可进行调整。
可理解到,在满足强弱电隔离、防信号干扰、散热等要求的情况下,能够有效利用基板100的面积,使各个电路安装更加紧凑,有效缩小基板100的面积,从而有利于减小电控板1000整体的体积,而且可以节省基板100的材料,降低电控板1000的成本。
参照图2所示,各个电路中的器件均布置在基板100的正面上,各器件的引脚可穿过基板100,在基板100的背面(附图未示出)将器件的引脚进行焊接固定,结构更加稳定可靠。
可以理解的是,参照图1所示,主控制电路200所占的面积最小,整流与逆变电路300所占的面积最大,实施例中将第一安装区110与第二安装区120均沿基板100的长度方向延伸,第二安装区120的长度大于第一安装区110的长度,第二安装区120的宽度大于第一安装区110的宽度,且第一安装区110的宽度与第二安装区120的宽度之和等于基板100的宽度,使第一安装区110和第二安装区120能够并列排布在基板100的左侧,且能够沿宽度方向充分基板100左侧的空间。
由于第二安装区120占用的面积较大,为了充分利用基板100右侧的空间,实施例中将第三安装区130设置在第二安装区120的右侧,且第三安装区130沿基板100的宽度方 向延伸,使第二安装区120的长度与第三安装区130的宽度之和等于基板100的长度,第二安装区120的宽度与第三安装区130的长度接近。
可理解到,第四安装区140与第三安装区130并列排布在基板100的右侧,使第四安装区140的宽度与第三安装区130的长度之和等于基板100的宽度。第四安装区140沿基板100的长度方向延伸,使第四安装区140的长度与第一安装区110的长度之和等于基板100的长度。
也就是说,沿基板100的左右方向,第一安装区110与第四安装区140相邻,第二安装区120与第三安装区130相邻。
参照图1所示,第一安装区110、第二安装区120、第三安装区130和第四安装区140均大致呈矩形,通过将四个安装区的长度和宽度尺寸进行合理设置,使得四个安装区能够紧密组合形成的面积与基板100的面积基本一致,使各个电路的布局能够充分利用基板100的面积,安装更加紧凑,布局设计得到优化,各个模块电路的分布更加合理,能够有效减小基板100的面积,从而减小电控板1000的整体体积,安装灵活性更高,更加便利,有利于提高空调室外机的装配效率。
可以理解的是,在基板100的长度方向上,安装区两两并排设置;同时在基板100的宽度方向上,安装区也是两两并排设置。相对于将四个安装区沿长度方向依次排列的布局结构,可有效缩小基板100的长度。
需要说明的是,各个安装区的位置不限于上述实施例所示的布局,在一些实施例中,可以将第一安装区110和第二安装区120设置靠近基板100的右侧,第三安装区130和第四安装区140设置靠近基板100的左侧。
例如,第一安装区110位于基板100的右上角位置,第二安装区120位于基板100的右下角位置,第三安装区130位于基板100的左下角位置,第四安装区140位于基板100的左上角位置;也可以是第一安装区110与第二安装区120的位置交换,第三安装区130与第四安装区140的位置交换。
此外,安装区的形状不限于上述实施例中所示的矩形,也可以是方形或其它多边形形状。例如,第二安装区120的形状可以是方形,第一安装区110和第三安装区130的形状为矩形,第四安装区140的形状可调整为“L”形,第四安装区140均与第一安装区110、第二安装区120和第三安装区130相邻,使各个安装区能够紧密配合组成整体为矩形形状。
可以理解的是,采用上述图1所示实施例的布局,能够使各个电路安装更加紧凑,从而有效减小电路占用基板100的面积,也就是说,采用小尺寸基板100可以实现电控板1000各个模块电路的安装。在一些实施例中,基板100的长度L为178mm,基板100的宽度W 为138mm,相对于传统的电控板,可大大减小电控板1000的整体体积,安装更加灵活方便。需要说明的是,通过对电控板1000的模块电路进行优化布局,可使基板100的尺寸满足L≤178mm且W≤138mm,具体可根据实际安装要求进行选择。
参照图3所示,图3所示为各个电路中的主要功能器件的布局示意图。实施例中以笛卡尔坐标系作为参考坐标,对主要功能器件的安装位置进行说明,根据笛卡尔坐标系对各电路的布局进行优化,使布局设计更加合理,可得到优选的布局方案。
具体来说,参照图3所示,基板100的正面可理解为笛卡尔坐标所在的平面,其中,以基板100右上角的顶角位置作为坐标系的原点,基板100的长度方向为X轴的方向,基板100的宽度方向为Y轴的方向,不考虑Z轴方向,坐标系内的尺寸单位为mm(毫米)。
参照图3所示,在第一安装区110内,以第一位置点为圆心、R1为半径形成的圆形区域为第一圆形区域111,其中,第一位置点与原点沿长度方向的距离为X1,第一位置点与原点沿宽度方向的距离为Y1,满足:X1=155mm,Y1=15mm,R1=10mm,根据笛卡尔坐标系可理解到,第一位置点在坐标系中的坐标为(-155,-15),也就是说,第一圆形区域111的圆心坐标为(-155,-15),第一圆形区域111的半径为10mm。
可理解到,第一圆形区域111位于第一安装区110内,主控制电路200的控制芯片210可安装在第一圆形区域111内,也就是说,控制芯片210的可调整范围是在基板100上以坐标(-155,-15)为圆心、10mm为半径所形成的第一圆形区域111内,例如,以控制芯片210的中心点作为参照点,控制芯片210可设置在第一圆形区域111的圆心位置,即控制芯片210的中心点与坐标点(-155,-15)重合;也可以将控制芯片210设置在第一圆形区域111的边缘位置或圆心与边缘之间的任意位置,例如,控制芯片210的中心点坐标可以是(-160,-20)、(-150,-10)等,具体不再进一步限定,可根据实际安装要求进行选择,从而实现对控制芯片210的布局优化,被动元器件根据控制芯片210的位置进行排布,充分利用第一安装区110的面积。
需要说明的是,由于笛卡尔坐标系的原点位于基板100的右上角,根据坐标系的原理可理解到,第一安装区110、第二安装区120、第三安装区130和第四安装区140均位于坐标轴的负值区域,也就是说,在相应安装区内,在X轴和Y轴方向均采用负值表示相应的坐标,坐标点与原点的距离按正值来计算。
参照图2和图3所示,整流与逆变电路300包括有智能功率模块310和整流模块320,其中智能功率模块310应用于逆变电路中,整流模块320应用于整流电路中,整流模块320设有整流桥堆。第二安装区120内包括有第二圆形区域121、第三圆形区域122和第三圆形区域122,智能功率模块310的可调整范围是在第二圆形区域121内,整流模块320的 可调整范围是在第三圆形区域122内。
具体来说,参照图3所示,第二圆形区域121是以第二位置点为圆心、R2为半径的圆形,第二位置点与原点沿长度方向的距离X2=150mm,第二位置点与原点沿宽度方向的距离Y2=55mm,半径R2=10mm,第二圆形区域121的圆心坐标为(-150,-55),也就是说,智能功率模块310的可调整范围是以坐标(-150,-55)为圆心、10mm为半径的区域内。
参照图3所示,第三圆形区域122是以第三位置点为圆心、R3为半径的圆形,第三位置点与原点沿长度方向的距离X3=150mm,第三位置点与原点沿宽度方向的距离Y3=100mm,半径R3=15mm,第三圆形区域122的圆心坐标为(-150,-100),也就是说整流模块320的可调整范围是以坐标(-150,-100)为圆心、15mm为半径的区域内。
参照图2和图3所示,实施例中,整流与逆变电路300还包括有电解电容,智能功率模块310和整流模块320设置靠近第二安装区120的左侧,电解电容设置靠近第二安装区120的右侧。具体的,电解电容包括第一电解电容330和第二电解电容340,第二安装区120内设有第四圆形区域123和第五圆形区域124,第一电解电容330在第四圆形区域123内调整位置,第二电解电容340在第五圆形区域124内调整位置。
参照图3所示,其中,第四圆形区域123是以第四位置点为圆心、R4为半径的圆形,第四位置点与原点沿长度方向的距离X4=78mm,第四位置点与原点沿宽度方向的距离Y4=74mm,半径R4=20mm,第四圆形区域123的圆心坐标为(-78,-74),也就是说,第一电解电容330的可调整范围是以坐标(-78,-74)为圆心、20mm为半径的区域内。
参照图3所示,第五圆形区域124是以第五位置点为圆心、R5为半径的圆形,第五位置点与原点沿长度方向的距离X5=80mm,第五位置点与原点沿宽度方向的距离Y5=110mm,半径R5=20mm,第五圆形区域124的圆心坐标为(-80,-110),也就是说,第二电解电容340的可调整范围是以坐标(-80,-110)为圆心、20mm为半径的区域内。
可以理解的是,通过将第一电解电容330和第二电解电容340分别在上述第四圆形区域123和第五圆形区域124内进行调整,使第一电解电容330与第二电解电容340并排设置,并能够满足使两个电解电容与散热器360隔开一定距离,降低散热器360对电解电容的影响,从而实现对整流与逆变电路300的布局优化,充分利用第二安装区120的面积,布局设计更加合理。
需要说明的是,智能功率模块310和整流模块320均为集成模块,考虑到智能功率模块310和整流模块320在工作时发热量较大,实施例中,在第二安装区120增加散热器360,通过散热器360对智能功率模块310和整流模块320散热,能够有效降低智能功率模块310和整流模块320的工作温度,提高电控板1000运行的可靠性。
具体来说,参照图4所示,在第二安装区120位置设置支架350,散热器360安装在支架350上,从而使散热器360得到支撑,减小散热器360对智能功率模块310和整流模块320的挤压。其中,实施例中散热器360的上表面分布有散热片,散热器360的底面为导热面,装配时,导热面能够与智能功率模块310和整流模块320的表面接触,从而使智能功率模块310和整流模块320产生的热量传递至散热器360,并通过散热片进行散热。
参照图4和图5所示,图4中示出支架350与基板100的连接示意图,其中,支架350设置围绕在智能功率模块310和整流模块320的外侧;图5中示出散热器360的装配示意图,散热片朝向垂直于基板100正面的方向延伸,散热器360与周边的器件隔开一定的安全距离,以保证散热性能。考虑到支架350在第二安装区120内占用一定的空间,因此第二安装区120的面积相对于其它安装区的面积会更大。
参照图1和图2所示,电源输入电路400位于第三安装区130内,交流电经过电源输入电路400后通过整流电流转为直流电,其中,电源输入电路400包括有共模电感410,共模电感410设置靠近基板100的右下角。
参照图1所示,功能接口电路500包括薄膜电容510和多个插座520,插座520用于连接空调室外机内的相关负载,例如,风机、压缩机、传感器等,不同负载连接不同的插座520,在第四安装区140内设置有不同类型的插座520。实施例中,将多个插座520沿第四安装区140的长度方向排列,且多个插座520均设置靠近基板100的边缘。
可以理解的是,通过将电控板1000与外部负载连接的插座520集中布局在第四安装区140,且插座520靠近基板100的边缘排列,如图1所示,插座520位于基板100的右上角位置。装配时,插座520集中在电控板1000的一侧,便于工人将各个负载接线的插头直接插到相应插座520上,提高插线效率,减小工时的耗费,而且接线可集中电控板1000的同一侧进行走线,使走线更合理,操作更简便,有效提高空调室外机的装配效率。
参照图1和图3所示,第四安装区140内包括有第六圆形区域141,第六圆形区域141是以第六位置点为圆心、R6为半径的圆形,第六位置点与原点沿长度方向的距离X6=51mm,第六位置点与原点沿宽度方向的距离Y6=26mm,半径R6=10mm,第六圆形区域141的圆心坐标为(-51,-26),也就是说,薄膜电容510的可调整范围是以坐标(-51,-26)为圆心、10mm为半径的区域内。
需要说明的是,电控板1000采用上述实施例的布局,能够使各个电路安装更加紧凑,有效利用基板100的面积,布局设计更加合理,能够控制基板100的长度小于等于178mm,宽度小于等于138mm,从而有效减小电控板1000的整体体积,安装灵活性更高,插线也更加简便,提高空调室外机的装配效率。
此外,本公开实施例的电控板1000无需采用电抗器和功率因数校正(Power Factor Correction,PFC)电感,减小装配电抗器和PFC电感的工艺步骤,从而有利于提高电控板1000的装配效率。
本公开实施例还提供的一种空调室外机(附图未示出),包括上述实施例的电控板1000。实施例的电控板1000安装在空调室外机内部,具体的,电控板1000可以安装在电控盒内组成电控盒组件,空调室外机内的风机、压缩机等部件均与电控板1000连接。电控板1000采用上述实施例的布局,使各个模块电路安装更加紧凑,布局设计更加合理,从而有效减小电控板1000的整体体积,安装灵活性更高,插线也更加简便,提高空调室外机的装配效率。
本公开实施例还提供的一种空调器(附图未示出),包括上述实施例的空调室外机,空调器采用了上述实施例的空调室外机的全部技术方案,因此至少具有上述实施例的技术方案所带来的所有有益效果。
上面结合附图对本公开实施例作了详细说明,但是本公开不限于上述实施例,在所属技术领域普通技术人员所具备的知识范围内,还可以在不脱离本公开宗旨的前提下作出各种变化。
