具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
下面结合附图1至图对散热组件、中框组件、壳体组件、终端设备进行详细描述。
请参照图1,并在必要时结合图2所示,散热组件100包括蒸发器10、冷凝器20及第一管道30。蒸发器10具有相对的输入端101和输出端102。冷凝器20具有相对的入口端201和出口端202。第一管道30连通蒸发器10的输出端102和冷凝器20的入口端201。第一管道30的至少部分内壁设置有毛细结构。
毛细结构可以用于储存工作流体。
这样,通过在第一管道30的至少部分内壁中设置毛细结构,可以有利于对第一管道30内存在的液态工作流体起到存储作用,防止第一管道内形成液滴而影响第一管道内蒸汽的流动,从而提高散热组件工作的稳定性。
在上述实施例的基础上,该散热组件100还包括第二管道40、补偿腔50及工作流体(未示出)。第二管道40连通冷凝器20的出口端202和蒸发器10的输入端101。补偿腔50位于第二管道40和蒸发器10之间且补偿腔50的内腔中填充有毛细结构。所述工作流体可以在蒸发器10、第一管道30、冷凝器20、第二管道40及补液腔50内循环流通。
需要说明的是,蒸发器10、第一管道30、冷凝器20、第二管道40及补液腔50中各个部分之间的相对位置可以根据待散热的终端设备的尺寸确认。例如:
该散热组件100在第一预设方向上的尺寸可以为0.2mm-1mm。该散热组件在第二预设方向上的尺寸可以为50mm-120mm。该散热组件100的整体在沿第三预设方向上的尺寸可以为30mm-70mm。
第二预设方向和第三预设方向垂直。例如:第二预设方向可以为散热部件100的长度方向L,第三预设方向可以为散热部件100的宽度方向W。相应地,第一预设方向与第二预设方向和第三预设方向所确定的平面呈一夹角,比如,第一预设方向可垂直于第二预设方向和第三预设方向所确定的平面。第一预设方向相应为厚度方向T。
在一些实施例中,请结合图2所示,补偿腔50的内腔中布满毛细结构65,形成蒸汽挡墙,以防止第二管道中的蒸汽流入蒸发器10,避免由于蒸汽流入蒸发器10带来的不利影响。
在一些实施例中,该补偿腔50在沿第三预设方向上的尺寸可以为3mm-20mm。补偿腔50在沿第二预设方向上的尺寸可以为30mm-20mm。
请继续结合图2所示,在一些实施例中,蒸发器10具有沿第一预设方向上相对设置的第一蒸发器侧壁11和第二蒸发器侧壁12。第二蒸发器侧壁12上设置有毛细结构61。
这里所说的第一预设方向,可以理解为散热组件100的厚度方向T。
该蒸发器10在沿第三预设方向上的尺寸可以为10mm-40mm。蒸发器10在沿第二预设方向上的尺寸可以为10mm-40mm。
蒸发器10内腔沿第一预设方向上尺寸范围为0.1mm-0.9mm。毛细结构61的厚度可设置为0.03mm-0.3mm。
当然,在其它一些实施例中,可以在第二蒸发器侧壁上设置毛细结构,而第一蒸发器侧壁上不设置毛细结构。第二蒸发器侧壁上设置的毛细结构的具体情况可参照上述相关描述。需要说明的是,在该散热组件用于终端设备时,蒸发器的设置有毛细结构的侧壁,可设置在更靠近热源的一侧,以将工作流体储于毛细结构处,有利于提高蒸发器的蒸发效果,从而提高散热组件的散热效果。
请继续结合图2所示,第一管道30具有沿第一预设方向上相对设置的第一管 道侧壁31和第二管道侧壁32,第一管道侧壁31的内壁设有毛细结构631,第二管道侧壁32的内壁设有毛细结构632。
该第一预设方向同样可以理解为散热组件100的厚度方向T。
该第一管道20在沿第三预设方向上的尺寸可以为5mm-40mm。第一管道20在沿第二预设方向上的尺寸可以为50mm-120mm。
这里第一管道30内腔沿第一预设方向上尺寸范围为0.1mm-0.9mm。毛细结构631的厚度可设置为0.001mm-0.3mm,毛细结构632的厚度可设置为0.001mm-0.3mm。
在一些实施例中,第一管道30的内腔中具有设置毛细结构的第一毛细结构区域及位于所述第一毛细结构区域外的第一膨胀腔区域3013。这里的第一毛细结构区域包括设置毛细结构631的毛细结构区域3011和3012。
第一膨胀腔区域3013沿第一预设方向上的尺寸大于所述第一毛细结构区域沿第一预设方向上的尺寸,以提供足够的汽化后的工作流体流通,有利于保证散热组件100的散热效率。
这里第一膨胀腔区域3013沿第一预设方向上的尺寸大于所述第一毛细结构区域沿第一预设方向上的尺寸,可以理解为D3>D1+D2。
在一些实施例中,第一膨胀腔区域3013沿第一预设方向上的尺寸与所述第一毛细结构区域沿第一预设方向上的尺寸之间的比值大于2,更有利于以保证第一管道30内有足够的空间供汽化后的工作流体流通。
这里第一膨胀腔区域3013沿第一预设方向上的尺寸与所述第一毛细结构区域沿第一预设方向上的尺寸之间的比值大于2,可以理解为D3>2(D1+D2)。
当然,在其它一些实施例中,也可仅在第一管道侧壁的内壁或第二管道侧壁的内壁设有毛细结构。可选的,该毛细结构的的厚度可设置为0.001mm-0.3mm。该毛细结构及第一管道的具体特征均可参考上述描述。
请继续结合图2所示,第二管道40具有沿第一预设方向上相对设置的第三管道侧壁41、第四管道侧壁42;其中,第三管道侧壁41的内壁设有毛细结构641,第四管道侧壁42的内壁上设有毛细结构642。
该第二管道40在沿第三预设方向上的尺寸可以为5mm-30mm。第二管道40在沿第二预设方向上的尺寸可以为50mm-120mm。毛细结构641、642的厚度分别可设 置为0.05mm-1mm。需要说明的是,可以根据实际需求调整第二管道40的尺寸范围,以上有关第二管道40的尺寸范围的描述只是示例并非限定。
在一些实施例中,第二管道40的内腔中具有设置毛细结构的第二毛细结构区域(包括4011和4012所指两个区域)和位于所述第二毛细结构区域外的第二膨胀腔区域4013,如此使得第二管道留有膨胀空间,以便工作流体更加通畅的流动,且能够防止水结冰胀管。
在一些实施例中,第二膨胀腔区域4013在第一预设方向上的尺寸可以为0.03mm-0.5mm,能够很好地防止水结冰胀管。
当然,在另一些实施例中,可在第三管道侧壁、第四管道侧壁中一个的内壁上设置有毛细结构。
此外,在又一些实施例中,第二管道40的内腔中可布满毛细结构。
请继续结合图2,冷凝器20具有沿第一预设方向上相对设置的第一冷凝器侧壁21和第二冷凝器侧壁22。第一冷凝器侧壁21设有毛细结构621,第二冷凝器侧壁22的内壁上设有毛细结构622。
该第一预设方向同样可以理解为散热组件100的厚度方向T。这里毛细结构621和毛细结构622的厚度均可控制在0.001mm-0.3mm。
该冷凝器20在沿第三预设方向上的尺寸(可以理解为宽度尺寸)可以为30mm-70mm。冷凝器20在沿第二预设方向上的尺寸(可以理解为长度尺寸)可以为10mm-50mm。
当然,在其它一些实施例中,也可仅在第一冷凝器侧壁和第二冷凝器侧壁中一个的内壁上设置毛细结构。可选的,该毛细结构的尺寸可控制在0.001mm-0.3mm。该毛细结构其他具体情况可参照上述相关描述。
请继续结合图2所示,在一些实施例中,散热组件100具有沿第一预设方向(比如厚度方向T)上层叠设置的第一盖板1001和第二盖板1002,第一盖板1001和第二盖板1002中至少一个上设有毛细结构,形成蒸发器10、冷凝器20、第一管道30、第二管道40及补偿腔50。
在一些实施例中,第一盖板1001和第二盖板1002中至少一个上设有间隔的多个支撑柱1003,以对第一盖板1001和第二盖板1002进行支撑,以保证散热组件的内 腔的形状,防止第一盖板1001和第二盖板1002变形带来的不利影响。多个支撑柱1003位于蒸发器10、冷凝器20、第一管道30、第二管道40和补偿腔50中至少一个的内腔中。
比如图2所示,蒸发器10、冷凝器20、第一管道30、第二管道40和补偿腔50的内腔中均设有支撑柱1003。
请参照图1所示,第一管道30和第二管道40之间设置有开孔103。开孔103贯穿第一盖板1001和第二盖板1002。
在一些实施例中,沿第一管道30朝向第二管道40的方向上,开孔103靠近蒸发器10一端的尺寸大于开孔103靠近冷凝器20一端的尺寸,以为靠近蒸发器10一端结构的受热膨胀提供足够的空间。
请参照图1所示,在一些实施例中,沿第一管道30朝向第二管道40的方向上,开孔103的最小尺寸D4大于或等于0.1mm,以保证开孔103的存在,以为散热组件100在受热膨胀时预留一定的膨胀空间。
在一些实施例中,沿第一管道30朝向第二管道40的方向上,开孔103的最小尺寸小于或等于2cm,以使得开孔103不至于太大,使得在该方向上,散热组件100的尺寸不至于太大。
在一些实施例中,所述毛细结构包括金属网毛细结构、金属线编织绳毛细、蚀刻沟槽毛细结构、金属粉烧结毛细结构和泡沫金属毛细结构中的一种或多种的组合。
在一些实施例中,散热组件100的侧边缘设有向外延伸的第一安装部(即一裙边结构),以用于与周边其他结构进行组件。
请参照图3和图4所示,本申请另提供一种散热组件200。与上述散热组件100的结构大致相同。相同或相似之处可参照上述散热组件100中的相关描述。这里仅针对不同之处进行描述。该散热组件200与上述不同的是,开孔103在第一管道朝向第二管道的方向上,整体收窄,以使得散热组件200在该方向上的整体尺寸可以做到更小,在组装时能够为周围其他结构提供足够空间,也有利于所组装成的产品在该对应于第一管道朝向第二管道方向上整体尺寸的控制,有利于所组装成的产品小型化。

本申请另提供一种壳体组件。可结合图10所示,所述壳体组件包括壳体600以及如上所述的散热组件300。散热组件300设置于壳体600内侧。当然,这里的散热组件300还可以替换为散热组件100、散热组件200或其他散热组件。

在一些实施例中,这里所说的第一预设方向可以理解为图8所示终端设备1000的厚度方向T0。该终端设备1000的厚度方向T0与散热模组散热部件200的厚度方向T一致。
可选的,该终端设备1000的长度方向L0与散热组件200的长度方向L一致,该终端设备1000的宽度方向W0与散热组件200的宽度方向W一致。
在一些实施例中,热源区域700设置有至少一个热源器件,比如终端设备1000的中央处理器(CPU)701,控制电路板(PCB)702。所述热源器件与散热组件200的蒸发器10对应设置,即所述热源器件与散热组件200的蒸发器10在第一预设方向上的正投影至少部分重叠,以通过蒸发器20进行散热。
该终端设备1000包括中框400、屏幕500和壳体600。中框400、散热组件200 及所述热源器件设于屏幕500和壳体600之间。
散热组件200设于中框400上,且散热组件200位于所述热源器件和屏幕500之间。
该终端设备1000还可包括电池800。该电池800可与散热组件200的冷凝器对应设置。即电池800与散热组件200的冷凝器在第一预设方向上的正投影至少部分重叠。
请参照图9和图10所示,本申请还提供一种终端设备2000,该终端设备2000与上述终端设备1000相比,增设一散热组件300。该终端设备2000与上述终端设备1000的相同或相似之处可以参照上述相关描述。散热组件300设于壳体600内侧,中框400及所述热源器件位于散热组件300背离壳体600的一侧。
在一些实施例中,终端设备2000设有位于热源区域700对端的无线充电结构900,比如无线充电线圈。散热组件300的蒸发器10、冷凝器20、第一管道30及第二管道40围成一位于散热组件300中部的避让口(可以理解为图5所示的开孔103),无线充电结构900与所述避让口对应设置,以便于应用于无限充电终端设备。这里所说的无线充电结构900与所述避让口对应设置,可以理解为无线充电结构900沿第一预设方向上的正投影至少部分位于所述避让口中。优选地,无线充电结构900沿第一预设方向上的正投影全部位于所述避让口中,以保证无线充电的效率。
继续参见图9和图10,第一管道30及第二管道40分别与无线充电结构900在第一预设方向上的正投影不重叠。
此外,需要说明的是,在其它终端设备中,还可仅设置一仅位于热源器件和壳体之间的散热组件。该设置于热源器件和壳体之间的散热组件还可替换为散热组件100、散热组件200或其它散热组件。替换为散热组件10或散热组件200的终端设备,其可不是无限充电终端设备。
需要说明的是,这里所说的终端设备,可以为手机、平板电脑、笔记本电脑等电子终端。
本申请另提供一种散热组件的制造方法。请参照图11,并在必要时结合图12所示,所述制造方法可用于制作如上所述的散热组件。所述制造方法包括如下步骤S101、步骤S103及步骤S105:
在步骤S101中,提供第一盖板和第二盖板;
在步骤S103中,在所述第一盖板和第二盖板中的至少一个上形成毛细结构;
在步骤S105中,将所述第一盖板和所述第二盖板对合组装,形成所述散热组件。
结合图12所示,在步骤S101中,提供第一盖板1001和第二盖板1002。需要说明的是,该第一盖板1001和第二盖板1002为对应形成散热组件200的盖板。其他散热组件的盖板可根据具体情况进行设置。
在一些实施例中,在步骤S103中的所述在第一盖板1001和第二盖板1002中的至少一个上形成毛细结构可包括:
采用刻蚀的方式和烧结方式中的至少一种,在第一盖板1001和盖板1002中的至少一个上形成毛细结构60。
进一步,在一些实施例中,在提供第一盖板1001和第二盖板1002后,所述方法包括:
采用刻蚀的方式和烧结方式的至少一种,在第一盖板1001和第二盖板1002中的至少一个上形成支撑柱。这里支撑柱可以和毛细结构同步形成。
在一些实施例中,在将第一盖板1001和第二盖板1002对合组装之后,所述方法还包括如下步骤S1051和S152:
在步骤S1051中,注入工作流体。
在步骤S1052中,对注入工作流体处进行封口。
这里所说的工作流体可以采用水。当然也可采用其他能够用于散热结构中的冷媒。
在一些实施例中,请结合图12所示,第一盖板1001的一端向外延伸有用于形成注液结构的第一注液部1005,第二盖板1002的一端设有向外延伸并与第一注液部1005对应的第二注液部1006。第一注液部1005和第二注液部1006二者的结构基本一样。
在步骤S103形成毛细结构之后,所述方法还包括如下步骤S104
步骤S104:将所述第一注液部和所述第二注液部对应组装(即对齐组装),形成注液结构。
该注液结构具有连通散热组件和外界的注液结构内腔。这里注液结构内腔与蒸发器的内腔连通。
该步骤S104可与步骤S105中将第一盖板1001和第二盖板1002对合组装同步实现。
相应的地,所述步骤S1051可通过如下步骤实现:
通过所述注液结构注入工作流体。
相应地,在通过所述注液结构向内部注入工作流体之后,所述方法包括:
去除所述注液结构,并在所述注液结构处进行真空封口。
需要说明的是,对于通过这种外延的注液结构进行注入工作流体的,在一些实施例中,上述在步骤S1052,对注入工作流体处进行封口,可以分如下两步实现:首先对注液结构的外端(即注液结构背离散热组件的一端)进行真空封口;然后再将注液结构去除,并对散热组件边缘上连接注液结构的连接处进行真空封口。
对注液结构的外端进行真空封口后可以对散热组件进行操作,比如调整散热组件的蒸发器所在的一端朝上,对于散热组件内腔中预留的空气流入注液结构的内端。进而再将注液结构去除。步骤S1052采用这种方式进行封口,有利于提高散热组件内腔中的真空度,避免散热组件的内腔中由于混入过多空气而影响散热效果。
需要说明的是在真空封口后,该方法后续还可包括多个对散热组件进行产品测试的方法。
在本公开中,所述结构实施例与方法实施例在不冲突的情况下,可以互为补充。
