具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本 发明实施例中的附图， 对本发明实施例中的技术方案进行清楚、 完整地描 述， 显然，所描述的实施例是本发明一部分实施例， 而不是全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有作出创造性劳动前提 下所获得的所有其他实施例， 都属于本发明保护的范围。
图 2为本发明智能终端散热装置实施例一的结构示意图， 图 3为图 2 所示的智能终端散热装置内毛细结构的示意图， 本实施例中， 散热装置内 的毛细结构通常为多线缠绕的多捆金属丝， 可承受弯折， 穿过刚性部分和 柔性部分， 形成连续的毛细结构， 实现冷却后的液体通过毛细力回流到蒸 发端再次汽化， 本实施例中， 智能终端散热装置可以应用在智能终端中进 行散热， 还可以应用在可弯折的智能穿戴终端以及未来出现的可弯折智能 手机中进行散热， 所述智能终端散热装置包括：
至少一根柔性热管， 即智能终端散热装置可以由一根柔性热管组成， 也可以由多根柔性热管组成， 当智能终端的主体中包含多个发热器件时， 可以选用多根柔性热管， 多根柔性热管可以并联连接， 也可以串联连接， 需要说明的是， 本实施例中的柔性热管还可以采用高导热材料替代， 如内 嵌铜箔、 内嵌石墨管、 内嵌高导热编织物， 但优选的为热管， 本实施例中， 当智能终端散热装置包括一根柔性热管时， 如图 2所示， 所述柔性热管的 两端为冷凝端 201， 中间为蒸发端 202， 其中， 所述柔性热管两端的冷凝 端 201可以由一个热管刚性部分和多个热管柔性部分交替排列组成， 也可 以由多个热管刚性部分和多个热管柔性部分交替排列组成， 还可以由多个 热管刚性部分和一个热管柔性部分交替排列组成， 以及一个热管刚性部分 和一个热管柔性部分交替排列组成， 具体可以根据实际应用中所涉及的智 能终端的结构来设定， 本实施例中不加以限制， 所述柔性热管中间的蒸发 端 202可以只包括热管刚性部分， 还可以包括热管刚性部分和热管柔性部 分， 图 2中只示出蒸发端 202的刚性部分， 本实施例中， 所有的柔性部分 是由多节软体管组成的， 本实施例中， 如图 3所示， 所述柔性热管内设置 有毛细结构 30， 所述毛细结构 30为采用真空设计的柔性封闭件， 毛细结 构 30内装有沸点低， 容易挥发的液体， 在智能终端主体安装在所述柔性 热管的蒸发端 202上并开始工作时， 所述柔性热管的蒸发端 202受热， 蒸 发端 202处的液体可以迅速蒸发， 蒸气在微小的压力差下流向柔性热管两 个冷凝端 201， 并且释放出热量， 重新凝结成液体， 液体再靠多孔毛细材 料的毛细力流回蒸发端 202， 如此循环不止， 对智能终端主体的热源通过 热传导进行散热， 本实施例中， 由于冷凝端由一个或多个热管刚性部分以 及一个或多个热管柔性部分组成， 所以可以对弯折设备进行柔性散热。
本发明实施例提供的智能终端散热装置， 该智能终端散热装置通过在 柔性热管两端设置冷凝端， 中间设置蒸发端， 且冷凝端由一个或多个热管 刚性部分以及一个或多个热管柔性部分交替排列组成， 蒸发端至少包括一 热管刚性部分， 实现了弯折区域较多的可弯折设备的柔性散热， 解决了现 有散热设备对对弯折区域较多的可弯折设备散热时， 散热效果较差的技术 问题。
图 4为本发明智能终端散热装置实施例二的结构示意图，在上述实施例的 基础上， 本实施例中， 所述智能终端散热装置包括多根柔性热管， 为了说明 各柔性热管之间的关系， 本实施例中以所述智能终端散热装置包括两根柔性 热管为例进行说明， 如图 4所示， 所述智能终端散热装置包括： 第一柔性热管 41与第二柔性热管 42， 其中第一柔性热管 41与第二柔性热管 42是并联分布， 智能终端主体 43可以安装在所述第一柔性热管 41的蒸发端， 也可以安装在所 述第二柔性热管 42的蒸发端上， 还可以安装在第一柔性热管 41的蒸发端和第 二柔性热管 42的蒸发端， 具体可以根据智能终端主体 43的大小来选择安装位 置， 当智能终端主体 43安装在第一柔性热管 41的蒸发端和第二柔性热管 42的 蒸发端时， 第一柔性热管 41的蒸发端和第二柔性热管 42的蒸发端可以对同一 智能终端主体 43上的不同热源进行散热， 本实施例中的两个柔性热管内的毛 细结构可以参照图 3所示的毛细结构 30的分布。
图 5为本发明智能终端散热装置实施例三的结构示意图， 图 6为图 5 所示的智能终端散热装置内毛细结构的示意图 A， 图 7为图 5所示的智能 终端散热装置内毛细结构的示意图 B， 在上述实施例的基础上， 本实施例 中， 所述智能终端散热装置包括多根柔性热管， 为了说明各柔性热管之间 的关系， 本实施例中以所述智能终端散热装置包括两根柔性热管为例进行 说明， 本实施例中如图 5所示， 所述智能终端散热装置包括： 第一柔性热 管 51与第二柔性热管 52，其中第一柔性热管 51的蒸发端与第二柔性热管 52的蒸发端相互串联连接， 即第一柔性热管 51的蒸发端与第二柔性热管 52的蒸发端是相通的， 所述智能终端主体 53可以安装在第一柔性热管 51 的蒸发端和 /或第二柔性热管 52的蒸发端上， 本实施例中， 所述第一柔性 热管 51内的第一毛细结构 54以及第二柔性热管 52内的第二毛细结构 55 如图 6所示， 第一毛细结构 54和第二毛细结构 55通过第一柔性热管 51 蒸发端与第二柔性热管 52蒸发端串联处的第三毛细结构 56a相互连接， 其中为了能够更全面地对智能终端主体 53中的各器件进行散热， 所述第 三毛细结构 56a呈网状结构， 本实施例中， 通过将第一柔性热管 51的蒸 发端与第二柔性热管 52的蒸发端相互串联连接， 同时将第一柔性热管 51 内的第一毛细结构 54以及第二柔性热管 52内的第二毛细结构 55也相互 串联连接， 实现了同一智能终端主体 43上的不同热源有更多的毛细结构 进行散热， 提高了散热效果。
进一歩的， 本实施例中， 所述第一柔性热管 51内的第一毛细结构 54 以及第二柔性热管 52内的第二毛细结构 55的连接关系如图 7所示， 第一 毛细结构 54和第二毛细结构 55是并联的， 且在所述第一柔性热管 51的 蒸发端与所述第二柔性热管 52的蒸发端之间设置多个第四毛细结构 56b， 所述第四毛细结构 56b垂直设置的， 即当所述智能终端主体 53安装在第 一柔性热管 51蒸发端与第二柔性热管 52蒸发端并开始工作时， 所述第四 毛细结构 56b紧挨所述智能终端主体 53热源的顶部受热液体蒸发， 蒸汽 垂直地向所述第四毛细结构 56b的底部流动， 并且释放出热量， 重新凝结 成液体， 液体再靠多孔毛细材料的毛细力流回第四毛细结构 56b的顶部， 如此循环不止， 对智能终端主体 53的热源进行散热， 第四毛细结构 56b 的散热方式可以参照现有的冷板散热技术。
