图 4为本发明提供的单板冷却装置另一个实施例的俯视图。 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, 都属于本发明保护的范围。
本发明提供的单板冷却装置一个实施例, 该装置包括: 壳体和单板, 单 板与壳体内壁形成封闭空间, 壳体上设有冷却介质入口和冷却介质出口, 冷 却介质通过所述冷却介质入口流入所述单板与所述壳体内壁形成的封闭空 间, 流经所述单板上的器件后通过所述冷却介质出口流出, 单板上设有多个 器件;
单板上在与单板垂直的方向上设有隔板, 隔板将单板隔离成第一部分和 第二部分, 第一部分与第二部分之间具有通过口; 冷却介质从冷却介质入口 流入第一部分, 流经第一部分的器件后经由通过口流入第二部分, 流经第二 部分的器件后从冷却介质出口流出;
单板上还设有导流机构, 导流机构用于将从冷却介质入口流入第一部分 的冷却介质分流, 以使部分冷却介质直接导入第二部分。
其中, 单板通常为印刷电路板 ( Printed Circuit Board, PCB ) , 单板 上设有多个器件, 例如: 各种集成电路( Integrated Circuit , IC ) 芯片、 散热器、 连接器等器件。 隔板可以为平板结构, 也可以为曲面结构。 隔板设 置在单板上且设置方向与单板垂直(也包括近似垂直) , 将单板分为第一部 分和第二部分, 第一部分包括的器件和第二部分包括的器件分为位于隔板的 两侧。
可选的, 单板的边缘(例如方形单板的四个边)可以与壳体的内壁连接, 以使壳体内壁与单板之间形成封闭空间; 或者, 单板上设置各种器件的表面 可以与壳体的边缘连接, 以使壳体内壁与单板之间形成封闭空间。 如果单板 在实际使用当中通常竖直放置, 那么单板上设置的隔板, 其顶部可以与壳体 连接, 使隔板两侧在沿着隔板的延展方向上完全隔离开来; 如果单板在实际 使用当中通常水平放置, 那么单板上设置的隔板, 其顶部可以与壳体连接, 也可以不与壳体连接。
冷却介质具体可以是冷却气体, 也可以是冷却液体。 冷却介质入口可以 设置在壳体上靠近第一部分的位置, 从而使冷却介质通过冷却介质入口进入 第一部分, 对第一部分的器件进行冷却降温。
作为一种可行的实施方式, 隔板靠近冷却介质入口的一端可以与壳体的 内壁连接, 隔板远离冷却介质入口的一端可以与壳体的内壁之间具有缝隙, 使该缝隙作为第一部分和第二部分之间的通过口。 冷却介质从冷却介质入口 流入第一部分, 在经过第一部分的器件后, 冷却介质可以从该通过口流入第 二部分, 对第二部分的器件进行冷却降温。 作为另一种可行的实施方式, 隔 板与单板平行方向的两端都与壳体的内壁连接, 而第一部分与第二部分之间 的通过口可以设置在隔板上,并且可以位于隔板上远离冷却介质入口的一端。 类似的, 冷却介质从冷却介质入口流入第一部分, 在经过第一部分的器件后, 冷却介质可以通过设置在隔板上的通过口流入第二部分, 对第二部分的器件 进行冷却降温。
冷却介质出口可以设置在壳体上靠近第二部分的位置, 冷却介质从通过 口进入第二部分, 流经第二部分的器件后, 从冷却介质出口流出壳体。
由于从通过口流入第二部分的冷却介质, 已流经单板的第一部分, 冷却 介质的温度会升高, 影响对第二部分器件的冷却降温效果。 本发明实施例中, 可以在单板上设置导流机构, 该导流机构用于将从冷却介质入口流入第一部 分的部分冷却介质直接导入第二部分。
作为一种可行的实施方式, 导流机构可以与单板垂直设置 (包括近似垂 直设置) , 在与单板平行的方向上将从冷却介质入口流入的冷却介质进行分 流, 使部分冷却介质直接导入第二部分。
可以理解的是, 导流机构还可以与单板在垂直方向上成一定角度设置, 流, 从而使部分冷却介质直接导入第二部分。 的冷却介质进行分流的一个实施例, 如图 1所示, 导流机构 1可以设置为板状 结构,也可以设置为曲面结构。其一端可以设置在靠近冷却介质入口 2的位置, 另一端可以在靠近通过口 3的位置与隔板 4连接,隔板 4上可以设置一个或多个 喷口 41。冷却介质从冷却介质入口 2进入壳体 5内腔后,在导流机构 1的作用下, 将冷却介质分流为两部分, 一部分冷却介质进入导流机构 1与隔板 4之间, 可 以通过隔板 4上的喷口 41直接进入第二部分; 另一部分冷却介质流经第一部分 的器件后, 从通过口 3进入第二部分。 可以看出, 在导流机构 1的作用下, 一 部分冷却介质先对第一部分的器件进行冷却降温后 ,再从通过口 3进入第二部 分, 对第二部分的器件进行冷却降温; 另一部分冷却介质进入导流机构 1与隔 板 4之间, 通过隔板 4上的喷口 41直接进入第二部分, 直接对第二部分的器件 进行冷却降温 , 从而利于单板上第二部分的器件散热。
从通过口 3进入第二部分的冷却介质, 以及通过隔板 4上的喷口 41直接进 入第二部分的冷却介质对第二部分器件进行冷却降温后, 从冷却介质出口 6 流出壳体 5。
可选的, 可以在导流机构 1上靠近通过口 3的一端设置阻流板 7, 阻流板 7 可以为板状结构, 也可以为曲面结构。 该阻流板 7可以阻碍流经第一部分的器 件后经由通过口 3流入第二部分的冷却介质与通过隔板 4上的喷口 41导入第二 部分的冷却介质合流,从而避免通过隔板 4上的喷口 41导入第二部分的冷却介 质, 在经由通过口 3流入第二部分的冷却介质的作用下温度升高, 影响对第二 部分器件的冷却降温效果。 可选的, 为了配合导流机构, 实现有效地对从冷却介质入口 2进入的冷却 介质进行分流, 还可以在导流机构 1与隔板 4之间, 靠近通过口 3处的单板 8上 设有循环泵 9, 以使部分冷却介质加速导入隔板 4与导流机构 1之间。
