冷却器及冷却器的固定方法
技术领域
本发明涉及一种冷却器及该冷却器的固定方法,该冷却器用于冷却半导体模块,在用于将冷却器固定在基体上的连接区域也具备制冷剂流路,冷却效率高,且节省空间。
背景技术
面向实现低碳社会,正在加速导入使用了能量转换效率高的逆变电路的电源、电动机,以及应用这些电源、电动机的混合动力汽车、电动汽车等。在这些领域中,称为功率半导体元件的整流二极管、功率MOSFET(金属氧化物半导体场效应晶体管)、IGBT(绝缘栅双极型晶体管)、晶闸管等被用于大电流控制。功率半导体元件有时也会以单体组装在电路基板上,但也使用将多个功率半导体元件集成到一个封装内的半导体模块,或者也包含控制电路、驱动电路、保护电路等模块化而成的智能功率模块(IPM)。
也存在以下领域,在功率半导体元件中,虽然进行了降低通态电阻的相关设计,但仍无法避免伴随高输出化的发热量的增加,已经开始从风冷式向液冷式转移。尤其是关于搭载了多个功率半导体元件的半导体模块,由于发热量大,因此在冷却效率方面优选为液冷式。但是,如果设为液冷式,则将增加循环泵、二次冷却器等附属装置,零件数量增加,因此各个零件需要尽可能小型化。尤其在用于电动汽车时,由于安装空间有限,因此半导体模块及冷却器的小型化成为优先级最高的技术问题之一。
在冷却器的小型化中,设置在制冷剂流通的流路上的隔壁、散热片的结构优化最为重要,但除此之外,将冷却器安装在基体上所需的装配部的尺寸减小也很重要。
在专利文献1-4中公开有利用螺钉将半导体模块和冷却器连结固定的固定法。

具体实施方式
在本发明中,半导体模块的结构并没有特别限定,但可适用于例如具有如下所述的逆变电路的半导体模块等。
图1中示出将直流功率转换为三相交流的逆变电路1。该逆变电路1由一个半导体元件(三极管)11a和一个半导体元件(二极管)11b构成元件对2,将元件对2串联构成半桥3,将半桥3并联而构成。
图2(a)中示出搭载了该逆变电路1的半导体模块10的俯视示意图。即,在基板12上搭载半导体元件(三极管)11a和半导体元件(二极管)11b各一个,并通过导线(未图示)电连接,能够构成图1所示的元件对2。在半导体模块10上搭载两行三列共6个基板12,并按照图1所示的电路图,通过导线电连接,能够构成逆变电路1。
另外,半导体模块10能够搭载具备半导体元件(三极管)11a的栅极驱动控制和/或电路保护功能(短路、过流、控制电源电压下降、过热)的控制用集成电路13。具备控制用集成电路13的功率半导体模块被称为IPM(Intelligent Power Module,智能功率模块)。
另外,为了抑制噪声、测定温度,半导体模块10根据需要可搭载电容、电阻和/或热敏电阻等无源元件14。
图2(b)中示出半导体模块10的剖面示意图。
绝缘基板12a的表面及背面形成有导体层12b及12c,从而构成基板12。绝缘基板12a优选为热传导性优异的氮化铝、氧化铝等陶瓷基板。导体层12b及12c可由铜等金属形成。
半导体元件(三极管)11a及半导体元件(二极管)11b能够经由焊料层15接合在导体层12b上。
根据本发明的一个实施方式,基板12能够将其背面的导体层12c经由焊料层16直接接合在冷却器20上。
另外,根据本发明另一实施方式,基板12能够将其背面的导体层12c经由焊料层16接合在铜或者镀镍的铝等底板17上,并在该底板17的背面涂覆导热膏(サーマルグリース),按压到冷却器20上。
此外,半导体模块10可以在对半导体元件(三极管)11a、半导体元件(二极管)11b、控制用集成电路13、无源元件14及基板12利用导线进行布线后,填充包含硅凝胶或玻璃填料的热固性树脂并密封。
本发明的冷却器不仅可用于如上所述的半导体模块的冷却,也可用于由单芯片构成的大规模集成电路、分立半导体、或者无源元件、片式电阻、片式电感的冷却。
半导体元件(三极管)11a可使用通态电阻低、切换速度快的IGBT(Insulated Gate Bipolar Transistor,绝缘栅双极型晶体管)或者SiC-MOSFET。
另外,半导体元件(二极管)11b可使用通态电阻低、耐压高的SiC二极管。
作为半导体元件(三极管)11a,形成在Si基板上的传统结构的功率MOSFET与IGBT或SiC-MOSFET相比,通态电阻高、性能差,但由于内置有体二极管,因此不需要半导体元件(二极管)11b。因此,能够将逆变电路集成在一个芯片上,用于小功率用途。
本发明涉及用于冷却如上所述的半导体模块10的冷却器20及其固定方法。即,如图3(b)所示,设置有半导体模块10的冷却器20被固定在某些基体30上使用。
以往,为了向基体30固定,在冷却器20上制冷剂流路以外的部分形成有通孔,利用通过该通孔而插入的螺栓等螺钉,将冷却器20固定在基体30上。但是,在这种结构中,需要避开通孔来形成制冷剂流路,因此存在冷却器大型化、制冷剂流路的流动变差的问题。本发明是为了解决上述技术问题而完成的。
下面,参照图3、4,对本发明的冷却器及其固定方法的第一实施方式进行说明。图3(a)中示出本发明的第一实施方式的冷却器20的俯视示意图,图3(b)中示出其A-A’剖面示意图。
本发明的冷却器20由壁部21、散热片22、制冷剂导入口23及制冷剂排出口24构成,壁部21由第一壁部21a、第二壁部21b及侧壁部21c构成,其中,所述第一壁部21a与半导体模块10接合,且具有第一通孔26,所述第二壁部21b与所述第一壁部21a对置配置,且在与所述第一通孔26对置的位置上具备与基体30连接的连接区域27,所述侧壁部21c连接所述第一壁部21a的周围与所述第二壁部21b的周围,第二壁部21b在连接区域27具备第二通孔28。而且,在由第一壁部21a、第二壁部21b、侧壁部21c所围成的空间中形成有制冷剂导入流路25a、冷却流路25b、制冷剂排出流路25c。本发明中将所有这些流路统称为制冷剂流路。
在第一壁部21a连接有散热片22。散热片22可使用针式散热片、刀片式散热片、波纹式散热片。针式散热片的针可使用圆柱或者四棱柱的针,可进行方形配置或者交错配置。刀片式散热片和波纹式散热片可以设为平直的形状,以形成直线流路,但也可以设为使散热片波状起伏以使流路蜿蜒曲折的迂回式散热片、将散热片在纵向上分割,并在横向上偏置排列的偏置式散热片。
壁部21及散热片22优选使用热传导性高的材料来形成,例如铝、铝合金、铜、铜合金等金属材料,为了提高传导性,更优选通过焊接或者铸造一体成型。
该冷却器20中,制冷剂导入口23和制冷剂排出口24配置在冷却器的壁部21的对角线上。另外,第一通孔26和第二通孔28配置在冷却器的壁部21的四个角上。
冷却器20在使用时,制冷剂从制冷剂导入口23流入制冷剂导入流路25a,分散在形成于散热片22之间的多个冷却流路25b中流动,并在制冷剂排出流路25c中汇集,从制冷剂排出口24排出。通过制冷剂,第一壁部21a和散热片22被冷却,通过被冷却的第一壁部21a,半导体模块10被冷却。
接着,对将上述冷却器20固定在基体30上的方法进行说明。图4(a)中示出冷却器20的固定操作前的状态。图4(b)中示出冷却器20的固定操作中的状态。图4(c)中示出冷却器20的固定操作后的状态。
该实施方式中,在基体30上设置有用于固定冷却器20的固定用孔31。另外,第一通孔26的内径设为固定部件40及密封部件41可通过的大小,散热片22以不阻塞第一通孔26的方式配置,以不妨碍固定部件40及密封部件41的通过。
另外,第二通孔28的制冷剂导入流路25a及制冷剂排出流路25c侧的内径比所述第二通孔28的所述基体30侧的内径宽。第二通孔28的内径被扩大的部分构成了本发明中的“沟槽”。
另外,固定部件40优选为由头部和螺纹部构成的螺钉。在固定部件40由螺钉构成的情况下,固定用孔31设为该螺钉所旋合的螺孔。另外,在第二通孔28的制冷剂流路侧设置有上述沟槽,以收纳固定部件40的头部和密封部件41,使固定部件40的头部不突出到所述制冷剂流路。
螺钉的形状没有特别限定,但优选如短头螺钉、平头螺钉、盘头螺钉、埋头螺钉那样头部平坦,更优选短头螺钉和平头螺钉。
密封部件41没有特别限定,可使用O型环、橡胶垫片、PTFE冲裁垫片、密封胶条、液体密封材料。
准备如上所述的冷却器20的工序为本发明中的第一工序。
为了将上述冷却器20固定在基体30上,如图4(b)所示,将冷却器20定位设置在基体30上,并使第二壁部21b的外侧与基体30接触。该工序为本发明中的第二工序。
在该状态下,从第一通孔26插入固定部件40和密封部件41,经由密封部件41将固定部件40从冷却器20的内侧插入第二通孔28,并插入基体30的固定用孔31进行固定。在固定部件40由螺钉构成的情况下,能够通过将其旋入固定用孔31并紧固来进行固定。第二通孔28通过由固定用部材40的头部和第二壁部21b所夹持的密封部件41被气密性地密封。以上工序为本发明中的第三工序。
接着,在第一通孔26中,经由密封部件51插入盖50并固定,由此,能够气密性地堵塞第一通孔26。该工序为本发明中的第四工序。
盖50优选设置为不突出到所述制冷剂流路。另外,盖50优选为可从第一壁部21a自由装卸,例如,可使用由头部和螺纹部构成的螺钉。在该情况下,在第一通孔26的内周预先形成盖50的螺纹部所旋合的螺纹槽。
其结果,可在堵塞第一通孔26的盖50与插入第二通孔28的固定部件40之间确保制冷剂导入流路25a、制冷剂排出流路25c,在成为连接区域的第一通孔26、第二通孔28的部分上也能够形成制冷剂流路,因此,能够使冷却器20小型化,并且能够使制冷剂导入流路25a、制冷剂排出流路25c平直,使制冷剂流动良好。
接着,参照图5、6,对本发明的冷却器及其固定方法的第二实施方式进行说明。图5(a)中示出本发明第二实施方式的冷却器20a的俯视示意图,图5(b)中示出其A-A’剖面示意图。
该冷却器20a具有壁部21、散热片22、制冷剂导入口23及制冷剂排出口24,壁部21由第一壁部21a、第二壁部21b、侧壁部21c构成,所述第一壁部21a与半导体模块10接合,且具有第一通孔26,所述第二壁部21b与所述第一壁部21a对置配置,且在与所述第一通孔26对置的位置上具备与基体30连接的连接区域27,所述侧壁部21c连接所述第一壁部21a的周围和所述第二壁部21b的周围。
根据本发明的第二实施方式,在连接区域27中,优选从冷却器20的内侧形成凹陷,使第二壁部21b的壁厚变薄。
此外,冷却器20a除了连接区域27的形状之外,壁部21、散热片22、制冷剂导入口23及制冷剂排出口24能够使用与本发明的第一实施方式相同的部件。
接着,对将该冷却器20a固定在基体30上的方法进行说明。图6(a)中示出冷却器20a的固定操作前的状态。图6(b)中示出冷却器20a的固定操作中的状态。图6(c)中示出冷却器20a的固定操作后的状态。
本发明的第二实施方式中,基体30也可以在连接区域32中,在与冷却器20a接触的面的相反侧的面上形成凹陷,使壁厚变薄。
另外,第一通孔26的内径可设为连接装置60可通过的大小,散热片22能够以不阻塞第一通孔26的方式配置,以不妨碍连接装置60的通过。准备这样的冷却器20a的工序为本发明中的第一工序。
而且,该实施方式中,作为连接装置60,使用焊接工具。作为焊接工具,优选对冷却器20a的母材损害较少的点焊(搭接电阻焊)或者激光焊接。
首先,将冷却器20a定位设置在基体30上,并设为使第二壁部21b的外侧与基体30接触的状态。该工序为本发明的第二工序。
在该状态下,从第一通孔26插入构成连接装置60的焊接工具,通过将冷却器20a的连接区域27焊接在基体30的连接区域32上,将冷却器20a固定在基体30上。该工序为本发明的第三工序。
之后,将由焊接工具构成的连接装置60从第一通孔26拔出,并用盖50和密封部件41堵塞第一通孔26。该工序为本发明的第四工序。
在本发明的第二实施方式中,作为所述连接装置60,除了焊接工具之外,也可以使用钎焊工具等。在该情况下,在第二壁部21b的连接区域27与基体30的连接区域32之间预先设置钎料。
接着,对本发明的冷却器20的其它实施方式进行说明。
在图7所示的冷却器20b中,在制冷剂流路的中央部设置除去散热片22后的部分,并在这里也设置第一通孔26及第二通孔28。在该情况下,由于制冷剂流路的中央部也可以固定在基体上,因此,即使冷却器大型化,也能够牢固地进行固定。
在图8所示的冷却器20c中,将配置在冷却器的壁部21的四个角上的第一通孔26及第二通孔28减少至对角线上的两个角,在空出的位置配置导向壁29,控制制冷剂的流动,防止产生热点。
在图9所示的冷却器20d中,在冷却器的壁部21的中心线上配置制冷剂导入口23、制冷剂排出口24、第一通孔26、第二通孔28,并在空出的四个角上配置导向壁29。
在图10所示的冷却器20e中,在冷却器的壁部21的一侧配置制冷剂导入口23及制冷剂排出口24,为了实现流量的均匀化,在制冷剂导入流路25a及制冷剂导入流路25c上配置有导向壁29。
这样,根据本发明,能够结合制冷剂流路的设计比较自由地设定第一通孔26及第二通孔28的位置,能够促进冷却器的冷却效率的提高。
