电子功能组件在处于工作状态时会释放热量,当电子设备1内部的温度过高时,将影响电子功能组件的工作效率以及电子设备1的使用寿命,故需要设置液冷模组10,以对电子功能组件进行温升控制。
基于上述考虑,在一些可行性实现方式中,液冷模组10嵌入壳体20,以实现对设置在壳体限定区域内的电子功能组件温度控制。

电子功能组件在处于工作状态时会释放热量,当电子设备1内部的温度过高时,将影响电子功能组件的工作效率以及电子设备1的使用寿命,故需要设置液冷模组10,以对电子功能组件进行温升控制。
基于上述考虑,在一些可行性实现方式中,液冷模组10位于壳体20与电子功能组件之间,以实现对电子功能组件温度的控制。示例性的,请继续参阅图1,可以看出液冷模组10位于壳体20临近电子功能组件的一侧。液冷模组10可以实现对电子功能组件温度的控制。
在一些可行性实现方式中,液冷模组10可以作为电子功能组件封装一部分,进而实现对电子功能组件温度的控制。示例性的,请参阅图2,图2为电池的分解图,电池30可以包括依次堆叠设置的护板31、托盘32、电芯33和液冷模组10。液冷模组10作为电池的一部分,可以对电池实现温度的控制。
下面对液冷模组10的温度控制功能作以说明:
请继续参阅图1,液冷模组10可以包括:液冷模件100、泵200和工质(图中未画出)。工质填充在液冷模件100的腔体内。泵200与液冷模件100的腔体连通,泵200可以作为液冷模件100内工质的动力源,为工质的流动提供动力。
在流动的过程中,工质可以作为热量传递的载体,将热量带离电子功能组件,进而实现对电子功能组件温度的控制。
本申请实施例中液冷模件100的腔体为工质的流动提供流动的轨道/场所,因此在本申请实施例中,液冷模件100的腔体可以称之为流道。
本申请实施例不对泵200的种类作具体的限定,在一些可行性实现方式中,泵200可以采用微型压电液泵,微型压电液泵振幅≤50um,具有超薄,体积小,结构简单,压力高流量小,无电磁干扰,工作噪声小特点,可实现流体精密输送及控制,尤其适合手机、手表、配件等电子设备。
一些相关技术将工质的流动制备成可视化的效果,可以实现具有科技感的流动显示区域。流动显示区域可以起到标识器件或美化壳体作用,以提升用户使用电子设备的体验感。
目前实现液冷模组10中工质流动可视化的实现方式为:透明的液冷模件100搭配流动可视化的工质,即在需展示流动可视化效果的壳体20区域做透光处理,以使得设置在壳体内部的工质的可视化效果得以展示,在做透光处理的区域形成具有科技感的流动可视化区域。
相关技术公开的流动状态可视的工质包括:水和染料。由于,染料的存在可以使得工质显色,使得工质的流动过程可以呈现流动可视化效果。
具有颜色的工质可以在尺寸较大的液冷模组10呈现出流动可视化效果。应用在电子设备中的液冷模组10的尺寸较小(通常液冷模组10的腔体尺寸通常在微升数量级),相关技术公开的工质在电子设备中的流动可视化效果较差。
为了解决相关技术存在的技术问题,请参阅图3,本申请实施例第一方面公开一种工质。工质300包括:第一介质301和第二相302。第一介质301与第二相302之间存在液接界面A,工质移动的过程中,液接界面A会与用于容纳工质的腔体B相对移动,使得工质300具有流动可视化的效果。
下面对本申请实施例公开的工质的各组分作进一步的说明:
本申请实施例公开的工质包括:第一介质。第一介质一方面较佳的散热性能,保证工质可以 实现较佳的温度控制功能;另一方面第一介质需要与第二相形成液接界面,保证工质可以实现流动可视化功能。
作为一种可行性实现方式,第一介质的在工质中的质量分数大于或等于80%。示例性的,第一介质在工质中的质量分数可以包括:85%、90%、95%等。
本实现方式中,第一介质在工质中质量分数大于或等于80%,即工质含有较多的第一介质(第一介质具有较佳的散热性能),保证工质可以实现较佳的散热性能,工质改变单位温度时吸收的热量较多,工质可以实现较佳的温度控制功能。
本申请实施例不对第一介质包含介质的种类作具体的限定,凡是具有较佳的散热性能,且可以与第二相形成液接界面的介质均可以作为第一介质应用到本申请实施例中。
示例性的,在一些可行性实现方式中,第一介质可以包括:水(H2O)、液态金属等。
本申请实施例中,H2O和液态金属具有较佳的散热性能。H2O、液态金属作为第一介质可以使得工质可以实现较佳的散热性能,保证工质可以实现较佳的温度控制功能。
本申请实施例中工质还可以包括:水溶性盐。水溶性盐与水(第一介质)形成的溶液可以称之为盐溶液。
盐溶液中可以包括:阴离子和阳离子。阴离子和阳离子均具有强亲水性能。使得阴离子可以与H2O形成水合的阴离子,阳离子可以与H2O形成水合的阳离子。即H2O倾向于与阳离子/阴离子结合。
在第二相以小液滴的形式分散在H2O内形成乳状液时,H2O优先与阳离子和阴离子结合,导致小液滴表面的水化层的厚度降低,小液滴倾向于相互聚集形成第二相,进而恢复第一介质与第二相之间的液接界面。因此,本实现方式公开工质具有稳定的液接界面,采用该工质的液冷模组可以具有稳定的流动可视化效果。
本申请实施例不对上述盐溶液的颜色作具体的限定,在一可行性实现方式中,盐溶液可以为无色溶液。

有色盐可以改变第一介质的颜色,因此,在本申请实施例中有色盐也可以称之为水溶性染料,或无机染料。
本实现方式中,工质包括:水溶性染料。水溶性染料在第一介质中的溶解度大于在第二相中的溶解度,水溶性染料可以使得第一介质显色,水溶性染料的引入可以使得第一介质与第二相具有较大的颜色对比度,使得工质可以具有显著的流动可视化效果。

值得注意的是,第一介质的导热系数并不是一个定值。温度会对第一介质的热导系数产生影响。具体的,温度升高会加剧第一介质的分子热运动,使得热到介质可以传递更多的热量,即温度升高第一介质的导热系数也随之增大。本申请实施例涉及的热导系数除特殊说明外,可以理解为第一介质在25℃时的热导系数。
本实现方式中,25℃环境下,第一介质的热导系数大于或等于0.1W/m·k。第一介质具有较大的热导系数,单位长度的第一介质改变单位温度时吸收的热量较多,工质可以实现较佳的温度控制功能。
比热容(specificheat capacity),可以理解为单位质量第一介质的热容量。第一介质的比热容越高,单位质量的第一介质改变单位温度时吸收的热量越多,相应的工质的温度控制功能越显著。
值得注意的是,第一介质的比热容受温度影响。本申请实施例涉及的比热容除特殊说明外,可以理解为第一介质在25℃时的比热容。

粘度(viscosity),可以理解为第一介质对流动所表现的阻力。具体应用到本申请实施例中,第一介质的粘度越小,第一介质流动过程中受到的阻力越小,第一介质单位时间内传递的热量越多,工质的温度控制功能越显著。
值得注意的是,第一介质的粘度受温度的影响。本申请实施例涉及的粘度除特殊说明外,可以理解为第一介质在25℃时的粘度。
作为一种可行性实现方式,在25℃环境下,第一介质的粘度可以小于或等于50cp。示例性的,在25℃环境下,第一介质的粘度可以为:50cp、40cp、30cp、20cp、10cp等。

CH3-(CH2)n-CH3 等。
考虑到液接界面的稳定性与第二介质在第一介质中的溶解度相关。具体的,第二介质的相对分子质量越大,碳氢化合物在第一介质的溶解度越低,第二介质与第一介质之间的液接界面越稳定,工质流动可视化效果越稳定。
为了得到具有稳定流动可视化效果的工质,作为一种可行性实现方式,CH3-(CH2)n-CH3中n可以大于或等于5。
本实现方式中,CH3-(CH2)n-CH3中n大于或等于5,碳氢化合物在第一介质的溶解度较小,碳氢化合物与第一介质可以形成稳定的液接界面,保证工质可以实现稳定的流动可视化效果。
考虑到液接界面的稳定性与第二介质的沸点相关。具体的,第二介质的相对分子质量越大,第二介质的沸点越高,第二介质的热稳定性越好,第二介质与第一介质之间的液接界面越稳定,工质流动可视化效果越稳定。
为了得到具有稳定流动可视化效果的工质,作为一种可行性实现方式,CH3-(CH2)n-CH3中n可以大于或等于5。
本实现方式中,CH3-(CH2)n-CH3中n大于或等于5,碳氢化合物的沸点较高,碳氢化合物与第一介质可以形成稳定的液接界面,保证工质可以具有稳定的流动可视化效果。
考虑到第二介质的散热性能与第二介质的粘度相关。具体的,第二介质的相对分子质量越小,第二介质的粘度越低,第二介质的散热性能越好。
为了进一步改善工质中温度控制功能,作为一种可行性实现方式,CH3-(CH2)n-CH3中,n可以小于或等于11。

为了兼顾工质稳定流动可视化效果和较佳的温度控制功能,作为一种可行性实现方式,CH3-(CH2)n-CH3中n可以在5-11。
同理,作为一种可行性实现方式,中,n可以大于或等于5。作为一种可行性实现方式,n可以小于或等于11。作为一种可行性实现方式,n可以在5-11。
同理,作为一种可行性实现方式,中,n可以大于或等于0。作为一 种可行性实现方式,中,n可以小于或等于5。作为一种可行性实现方式,中,n可以在0-5。
同理,作为一种可行性实现方式,中,n可以大于或等于0。作为一种可行性实现方式,中,n可以小于或等于5。作为一种可行性实现方式,中,n可以在0-5,以兼顾工质稳定流动可视化效果和较佳的温度控制功能。在一些可行性实现方式中,杂原子化合物的分子结构式可以包括:
等。
本实现方式中,杂原子化合物(第二介质)的分子结构式中包括:苯环苯环具有较大的刚性,进而使得杂原子化合物具有较大的刚性,当杂原子化合物与第一介质发生乳化时,由于杂原子化合物具有较大的刚性,在破乳剂的作用下,杂原子化合物可以较快脱离第一介质的束缚彼此聚集成第二相,使得工质恢复液接界面,实现流动可视化效果。
在一些可行性实施例中,工质还可以包括:有机染料。有机染料在第二介质中的溶解度大于有机染料在第一介质中的溶解度,有机染料的引入可以增加第一介质与第二相的颜色对比度,使得工质可以具有显著的流动可视化效果。
至此完成对第二相的描述。
值得注意的是,工质在静止状态下,第一介质与第二介质之间存在液接界面。工质在流动状态下,第一介质与第二介质之间可能发生乳化,即第二介质以小液滴的形式分散在第一介质中。具体的,可以参阅如图4,可以看出,第一介质与第二介质发生乳化后,第二介质以小液滴的形式分散在第二介质中形成乳状液400,第一介质与第二介质之间的液接界面被破坏。工质丧失了流动可视化的功能。

作为一种可行性实现方式,烷基萘磺酸钠的分子结构式包括:
其中,R为疏水基团。
本申请实施例中疏水基团可以包括:环烷基、烷氧基、烷基等。
值得注意的是,仅是示例性的展示一种烷基萘磺酸钠中R和磺酸基(SO3Na-)的取代位置,上述取代位置并不构成限定。例如:在一些可行性实现方式中,SO3Na-可以与萘环上的C1、C2、C4连接。再例如:在一些可行性实现方式中,R可以与萘环上的C5、C6、C8连接。
本实现方式中,烷基萘磺酸钠的分子结构式中包括:(SO3Na-),使得烷基萘磺酸钠与第一介质的结合能力强于第二介质与第一介质的结合能力。在第二介质以小液滴的形式分散在第一介质内形成乳状液时,第一介质优先与SO3Na-结合,导致小液滴表面的水化层的厚度降低,小液滴倾向于相互聚集形成第二相,进而恢复第一介质与第二相之间的液接界面。

请继续参阅图6,作为一种可行性实现方式,液冷模件100可以包括:依次设置的覆盖层120、流道层130和覆盖层140。覆盖层120设置在流道层130的一侧,覆盖层140设置在流道层130的另一侧,覆盖层120、流道层130和覆盖层140围设形成腔体110。为了方便区分本申请实施例将其中一个覆盖层120称之为顶盖层120;将另一个覆盖层140称之为底盖层140。
作为一种可行性实现方式,流道层130包括:至少一个刚性基体131。刚性基体131设置在顶盖层120和底盖层140之间,用于支撑顶盖层120和底盖层140。

本申请实施例中,防蒸散层的密度大于覆盖层的密度,防蒸散层的设置可以加大工质逃离腔体的难度,即防蒸散层起到降低工质发生蒸散损失的作用。
另外,防蒸散层的可见光透过率大于或等于阈值,以保证液冷模组的流动可视化效果。
本申请实施例不对防蒸散层采用的材料作具体的限定,凡是可以避免工质发生蒸散损失材料均可以作为防蒸散层的材料应用到本申请实施例中。示例性的,防蒸散层采用的材料可以包括:聚酰亚胺层、聚偏二氯乙烯层或者金属薄膜层中的至少一种。
