在一实施例中,弹性连接组件101包括支撑杆1011和弹性件1012,支撑杆1011的第一端与安装框架12固定连接,弹性件1012的两端分别与支撑杆1011的第二端和散热器100连接。通过支撑杆1011的第一端与安装框架12固定连接,支撑杆1011的第二端与弹性件1012的一端连接,弹性件1012的另一端与散热器100连接,从而可以实现散热器100与安装框架12之间弹性连接,在安装框架12的作用下可以推动支撑杆1011和弹性件1012将散热器100往电路板11的方向按压,进而可以使散热器100抵接于电路板11,实现散热器100对电路板11上的芯片110进行散热。
进一步地,支撑杆1011设置有容置腔1013,支撑杆1011的第二端设置有与容置腔1013连通的开孔;弹性连接组件101还包括导杆1014,弹性件1012为弹簧,弹簧套设在导杆1014的外围,导杆1014的第一端与散热器100固定连接,导杆1014的第二端插置于容置腔1013内。通过在支撑杆1011内设置容置腔1013,在散热器100一侧设置导杆1014,导杆1014的第一端与散热器100固定连接,导杆1014的第二端插置于容置腔1013内,弹性件1012为弹簧,弹簧套设在导杆1014的外围,使得在安装框架12的作用下推动支撑杆1011和弹性件1012将散热器100往电路板11的方向按压时,导杆1014的第二端在容置腔1013中移动,起导向作用。
在一实施例中,弹性件1012的两端分别抵接于支撑杆1011的第二端和散热器100。弹性件1012采用抵接于支撑杆1011的第二端和散热器100的方式安装,在散热装置10安装的过程中,需要先将弹性件1012套设在导杆1014上,然后将导杆1014的第二端插置于容置腔1013内。在另一实施例中,弹性件1012的两端分别与支撑杆1011的第二端和散热器100固定连接。由于弹性件1012与支撑杆1011的第二端和散热器100固定连接,在散热装置10安装的过程中,直接将导杆1014的第二端穿过弹性件1012并插置于容置腔1013内即可。
进一步地,支撑杆1011的第二端的开孔为螺纹孔,导杆1014的第二端设 置为与螺纹孔相配合的螺杆。通过导杆1014的第二端的螺杆从支撑杆1011的第二端的螺纹孔旋入,可以将导杆1014的第二端插置于容置腔1013内时,且导杆1014的第二端不会脱离容置腔1013。
在一实施例中,弹性连接组件101还包括第一紧固螺钉1015,导杆1014的第一端开设有第一螺纹孔,导杆1014的第一端通过第一紧固螺钉1015和第一螺纹孔配合,与散热器100可拆卸连接。
在一实施例中,弹性连接组件101还包括第二紧固螺钉1016,支撑杆1011的第一端开设有第二螺纹孔,支撑杆1011的第二端通过第二紧固螺钉1016和第二螺纹孔配合,与安装框架12可拆卸连接。
在一实施例中,散热器100朝向电路板11一侧设置有导热件102,导热件102具体可以为片状导热材料,导热件102与电路板11上的芯片110相贴合。
请结合图1,本申请还提供一种电子设备,电子设备包括电路板11、安装框架12和散热装置10,散热装置10设置于电路板11和安装框架12之间,散热装置10为上述任意一种散热装置10。安装框架12可以是电子设备的机框上盖,也可以是设置于机框内的支架、固定架等结构。
请结合图1,在一应用场景中,散热装置10安装于电子设备的机框中,具体地,散热装置10设置于电子设备的电路板11和安装框架12之间,此时安装框架12为机框上盖,散热装置10可以按照以下顺序进行安装:将支撑杆1011通过第二紧固螺钉1016安装在机框上盖上,然后将导杆1014旋入支撑杆1011的容置腔1013内,将弹性件1012套设在导杆1014上,于是可以将贴有导热件102的散热器100通过第一紧固螺钉1015安装在导杆1014上,即实现将散热装置10安装在机框上盖上;接着,将装好散热装置10的机框上盖向下预压到装好电路板11的机框下盖13上,此时散热器100的导热件102正好与电路板11上的芯片110相贴合,然后紧固机框上盖和机框下盖13,整个安装过程完成。另外,当电路板11上有多个芯片110需要设置散热装置10时,只需要重复以上将散热装置10安装在机框上盖上的操作,将所有散热装置10安装好后再安装机框上盖和机框下盖13操作即可。可以发现,由于散热装置10的安装不占用电路板11的布局空间,使得散热装置10可在机框上盖上任意排布设置,可以同时使多颗大功耗芯片110全部安装散热装置10,进行弹性接触散热;并且,所有散热装置10随机框上盖整体向下压,有助于缓解芯片110受力不均现象,可以降低焊点损坏风险;另外,安装散热装置10无需再电路板11上开孔,与 电路板11上的器件不存在位置竞争关系,散热装置10的安装孔位设计更灵活,适应性强。
请结合图3至图5,其中,图3是一应用场景中改制前的电子设备与改制后的电子设备之间的产品状态结构对比示意图,图4是图3的改制后的电子设备采用现有设计的散热装置与本申请的散热装置时电路板的布局结构对比示意图,图5是图3的改制后的电子设备采用现有设计的散热装置与本申请的散热装置的设备结构对比示意图。在一应用场景中,图3左侧的电子设备为改制前的电子设备,其为户外55℃安装产品,为了拓宽市场,现需要将其改成图3右侧的电子设备,图3右侧的电子设备为改制后的电子设备,开发需求为:体积尽可能小,开发周期要尽可能短。改制前后产品需求规格参数对比如下表:
Figure PCTCN2021098399-appb-000001
通过图3可以发现,PCB板上芯片1/2/3需要安装散热器进行强化散热,原产品PCB板上没有安装散热器1/2/3的合适孔位,为实现散热器安装,推荐以下两种方案:
方案一:安装现有设计的散热装置,即将PCB板改版,增加十个螺钉孔;
方案二:安装本申请的散热装置,即直接借用原PCB,不改版。
请结合图4,两种不同的解决方案的关键参数信息对比如下表:
Figure PCTCN2021098399-appb-000002
然后,通过仿真可以得到图4的PCB板上关键芯片温度数据,不同散热器安装方案仿真得到的关键芯片温度数据对比如下表:
Figure PCTCN2021098399-appb-000003
可以发现,在散热上,方案一和方案二基本无差别,即本申请的散热装置亦能保证关键芯片的温度在规格范围内。
综上,将两种方案的优劣势进行对比,汇总如下表:
Figure PCTCN2021098399-appb-000004
Figure PCTCN2021098399-appb-000005
通过以上分析可知,采用方案二可以有效解决现有设计中螺钉孔占板问题,使产品体积做到更小;并且可以解决产品在PCB板不改版情况下的不同使用场景中的散热方案兼容问题;另外,PCB板可以直接借用原产品,降低了PCB板开发的物料、时间、人力成本。
本申请提供的散热装置和电子设备,散热装置通过弹性连接组件的一端固定连接于散热器,弹性连接组件的另一端用于弹性连接于电路板的安装框架,使得在将安装框架安装于电路板上的过程中,散热装置位于电路板和安装框架之间,弹性连接组件在安装框架的作用下可以将散热器往电路板的方向按压,进而可以使散热器抵接于电路板,从而可以对电路板上的芯片进行散热,本申请的散热装置无需通过在电路板上进行打孔来固定连接散热器,在散热器能满足散热的情况下,可以减少PCB开孔数量,使产品体积做到更小。
