为便于对本发明实施例技术方案的描述， 下文将以机拒作为本发明实 施例中待通风降噪的设备， 对本发明实施例技术方案进行说明， 其中的机 拒是可以安装电子部件， 例如电路板等的电子设备。 本领域技术人员可以 理解的是， 本发明实施例并不限于机拒的通风和降噪处理， 还可以用于其 它需要进行通风和降噪的设备中。 同时， 根据通风降噪装置中通风模块的 配合关系，以及与机拒的配合关系的不同，分别以不同的实施例进行说明。
实施例一 图 1A 为本发明实施例一提供的通风降噪装置的结构示意图； 图 1B 为本发明实施例中通风模块的立体透视结构示意图；图 1C为图 1B中通风 模块的剖面结构示意图。 如图 1A、 图 1B和图 1C所示， 本实施例通风降 噪装置包括至少一个通风模块 1 , 通风模块 1 内设置有至少两个空气通道 1 1 , 该至少两个空气通道 1 1依次首尾相通形成迂回风道； 通风模块 1上 还设置有第一通风口 12和第二通风口 13 , 其中， 第一通风口 12与风道的 一端连通， 第二通风口 13 与风道的另一端连通。 本实施例通风降噪装置 可安装在机拒外部的通风口处， 作为机拒的进风装置或出风装置， 并对机 拒运行中产生的噪声进行降噪处理， 吸收机拒运行过程中产生的噪声， 减 少机拒运行中产生的噪声对外界环境的影响。
本实施例中，通风模块 1的数量可以为 1个或 1个以上，实际应用中， 可根据机拒的通风量和降噪需要， 设置合适数量的通风模块 1 , 且多个通 风模块 1之间可层叠设置在一起， 安装在机拒外部的进风口或出风口处， 以作为机拒的进风装置或出风装置。 本实施例通风降噪装置可适用于进风 口和出风口分别设置在不同侧的机拒的通风和降噪。 后面将会对本发明实 施例在通风降噪系统中的应用进行详细说明。
本实施例中， 通风模块 1 内的风道， 是由多个空气通道 11首尾相通 所形成的迂回风道， 这里所述的迂回风道， 即指多个空气通道形成的回旋 宫式结构的风道长度较长， 且不是直线通道， 该迷宫式结构的风道可有效 对在其内传播的噪声进行降噪， 使得通风模块 1可具有较强的降噪能力。 实际应用中， 所述的多个空气通道 11 相会平行设置， 该相互平行设置的 多个通道依次首尾相连而形成具有回旋式结构的迂回风道。
本实施例中， 形成迷宫式结构的风道可以由 2个或 2个以上的空气通 道连通形成， 实际应用中， 可根据降噪需要， 设置合适数量的空气通道， 以得到具有合适长度的风道， 提高通风模块的降噪能力。 本实施例通风降噪装置安装在机拒的进风口和出风口时， 机拒运行时 产生的噪声可分别通过与机拒的进风口和出风口连通的第一通风口 12,进 入到通风模块 1的风道中， 而通风模块 1内迷宫式结构的风道可对进入的 噪声进行降噪处理， 使得从通风模块 1的第二通风口 13排出的噪声降低， 从而可减少机拒运行过程中产生的噪声对外界环境的影响。
本实施例中， 为提高通风模块的降噪能力， 还可在风道内设置降噪部 件， 例如， 可以在风道内设置主动式降噪部件， 或者在风道的内壁上设置 声学材料内衬， 以通过主动式降噪部件或声学材料来吸收进入风道内的噪 声。 其中， 所述的主动式降噪部件可以是由包括麦克风和喇叭组成的主动 降噪系统， 具体地， 该主动降噪系统可包括控制器、 麦克风和喇八， 控制 器可通过麦克风采集风道内的噪声信号， 并根据采集的噪声信号控制喇八 产生与采集的噪声信号相位相反的声音， 以与风道内的噪声叠加， 降低风 道内噪声的强度； 所述的声学材料内衬具体可以是具有吸声结构的内城， 例如亥姆霍兹共振器、 穿孔板吸声结构、 薄板共振吸声结构、 以及柔顺材 料构成的内衬等， 或者， 所述声学材料内衬， 也可以是多孔性吸声材料构 成的内衬， 多孔性吸声材料可以包括泡沫类， 如聚氨酯泡沫、 三聚氰胺泡 沫等， 纤维类， 如聚酯纤维、 离心玻璃棉等。
本实施例中，如图 1B和图 1C所示，上述的通风模块 1具体可以为具 有空腔的矩形结构， 该空腔内可设置有挡板 14, 以便利用挡板 14将空腔 分隔成首尾相通的至少两个空气通道 1 1。 采用矩形结构， 并通过设置挡板 的方式得到首尾连通的多个空气通道时， 挡板可通过插接的方式固定在通 风模块 1的内部， 使得通风模块 1具有制作方便、 成本较低的优点。
实际应用中， 根据应用场景或其它需要， 通风模块也可设置成其它合 适形状或结构， 以满足安装到机拒上的需要； 通风模块内的风道也可设置 成圆形或其它形状， 只要在通风模块内部可以形成迷宫式结构的风道， 满 足对机拒的降噪需要即可。 本实施例中， 通风模块 1上的第一通风口 12可用于与机拒上的进风 口或出风口连通设置， 以便将风道作为冷风进入机拒内的通道， 或者将风 道作为热风排出机拒的通道。 实际应用中， 可根据安装需要， 将第一通风 口 12和第二通风口 13设置在通风模块 1的合适位置， 优选地， 本实施例 中通风模块 1中的风道的两端位于通风模块 1的同一端，且第一通风口 12 位于通风模块 1靠近端部的侧面上， 第二通风口 13位于通风模块 1的端 面上， 以满足安装到机拒的需要。
本实施例中， 通风模块 1可直接安装到机拒上， 或者， 也可以通过其 它方式， 例如通过托架安装到机拒上。 优选地， 本实施例中通风降噪装置 还可包括有托架， 通风模块 1安装在该托架上， 从而可利用托架将整个通 风降噪装置固接在机拒上。
图 1D为本发明实施例中托架的结构示意图。 如图 1D所示， 为便于 各通风模块的安装， 托架 2上具有容纳各通风模块、 独立设置的安装腔体 21 , 使得各通风模块可拆卸的安装在相应的安装腔体 21 内， 这样， 在部 分通风模块损坏时，可直接将损坏的通风模块取出，更换或维护通风模块， 在更换和维护过程中， 不会影响其它模块的正常工作， 可便于通风降噪装 置的组装以及维护。 本领域技术人员可以理解的是， 托架 2可通过螺栓等 固定连接方式安装在机拒上， 且托架 2安装到机拒后， 各通风模块的第一 通风口可与相应的进风口或通风口连通。
实际应用中， 可根据机拒上设置的通风口的位置， 以及机拒外部的环 境， 如热风排出区域或冷风提供区域的位置， 将通风模块 1上的第一通风 口和第二通风口设置在合适的位置。 优选地， 本实施例中， 通风模块 1上 的第一通风口和第二通风口位于通风模块 1的同一端， 并设置在不同的侧 面上， 以适应各种机拒的通风和降噪需要。
本实施例提供的通风降噪装置， 通过在降噪模块内部设置首尾连通的 多个空气通道， 得迂回风道， 使得通风模块可具有较好的降噪能力， 通风 模块的风道可直接与机拒外部的进风口或出风口连通， 从而可通过迂回风 道吸收机拒运行时产生的噪声； 本实施例提供的通风降噪装置结构简单、 实现方便， 可直接安装在机拒的外部， 不影响机拒内部空间的布置， 在满 足机拒通风需要的同时， 可有效利用通风模块的风道结构对噪声进行降噪 处理， 减少机拒运行过程中产生的噪声对外界环境的影响； 本实施例通风 降噪装置直接安装于机拒的外部， 有利于通风降噪装置的安装和维护。
实施例二
图 2A为本发明实施例二提供的通风降噪系统的主视图； 图 2B为图 2A 中 A - A向的剖面示意图。 本实施例通风降噪系统包括机拒， 该机拒 的通风口处设置有通风降噪装置， 该通风降噪装置为采用上述图 1A〜图 1D所示的装置。 具体地， 如图 2A和图 2B所示， 本实施例通风降噪系统 中， 机拒 101的通风口包括分别设置在机拒 101两侧的进风口和出风口； 机拒 101的进风口和出风口处分别设置有通风降噪装置 201 , 该通风降噪 装置 201为采用上述图 1A所示的装置， 通风降噪装置 201 中通风模块 1 的第一通风口分别与机拒 101上的进风口和出风口连通。
本实施例中， 机拒运行时， 外界的冷风可通过设置在进风口处的通风 降噪装置 201进入机拒 101内部，在机拒 101内部经过热交换形成的热风， 又会从设置在出风口处的通风降噪装置 201排出， 空气的具体流动方向请 参见图 2A和图 2B所示的箭头方向； 同时， 在此过程中产生的噪声会进 入到通风降噪装置 201的各通风模块 1的风道中， 从而可利用各通风模块 1 的风道对进入的噪声进行降噪处理， 减少机拒运行过程中产生的噪声对 外界环境的影响。
本实施例中， 为保证机拒运行时的冷热隔离， 即进入机拒的外界冷风 区域和排出机拒而进入外界的热风区域相互隔离， 设置在进风口处的通风 降噪装置 201 内的通风模块 1 的第二通风口位于机拒的不同端， 如图 2B 所示箭头的空气流通方向。 本实施例中， 为使得机拒运行过程中产生的噪声大部分可进入到各通 风模块 1的风道中，机拒要密封设置，且机拒的外壳具有较强的隔声效果， 这样， 噪声就主要会由各通风模块 1中的风道进入到外界环境， 而噪声经 过各通风模块 1的风道的降噪处理后， 噪音就会变得非常小， 从而可有效 减少机拒运行过程中对外界环境的影响， 提高机拒的降噪效果。
本领域技术人员可以理解， 通风模块 1的数量越多， 对机拒运行中产 生的噪声的降噪效果也就越好， 实际应用中， 可根据机拒运行中的通风量 (即降温需要）以及产生的噪声的大小， 可安装具有合适数量通风模块的 通风降噪装置， 以满足机拒的通风和降噪需要。
本实施例中， 通风降噪装置中的各通风模块可层叠设置， 并与机拒上 设置的各通风口连通， 使得整个通风降噪系统可具有较好的通风、 降噪能 力， 且层叠设置的通风模块具有结构简单， 实现方便。
本领域技术人员可以理解， 根据实际降噪和通风需要， 也可仅在设备 的一侧安装有通风降噪装置， 例如机拒产生的噪声较小时， 只需要在机拒 的进风口设置通风降噪装置即可。

实施例七
图 7Α为本发明实施例七提供的通风降噪装置的主视图； 图 7Β为图 7Α中通风模块的立体透视结构示意图。 与上述图 3Α和图 3Β所示装置实 施例不同的是， 本实施例中的通风降噪装置中的通风模块可具有两个与机 拒连通的第二通风口， 使得通风降噪装置可安装在两个机拒之间， 实现对 两个机拒的通风和降噪。 具体地， 如图 7Α和图 7Β所示， 在上述图 1B和 图 1C所示通风模块的基础上， 本实施例中进风模块组 30和出风模块组 40中的通风模块 2上还设置有第三通风口 15 , 用于与机拒上的通风口连 通， 这样， 通风模块 2上的第一通风口 12和第三通风口 15可分别与相对 设置的两个机拒上的通风口连通， 从而使得本实施例通风降噪装置可安装 在相对设置的两个机拒之间， 与两个机拒的通风口连通， 将其中的进风模 块组 30和出风模块组 40可分别作为两个机拒的进风和排风装置。
本实施例中， 第一通风口 12和第三通风口 15对称设置， 以便于对称 设置的两个机拒上的进风口或出风口连通， 以便于通风降噪装置的安装。 本领域技术人员可以理解， 上述的第一通风口 12和第三通风口 15的具体 设置位置， 可根据待连通的两个机拒上的通风口的具体位置而设定， 实际 应用中可根据需要合理设置。
本实施例通风降噪装置中的通风模块具有两个与机拒的通风口连通 的通风口， 可应用于对称设置的两个机拒中， 可同时作为两个机拒的进风 装置和出风装置， 并对机拒运行过程中产生的噪声进行降噪处理， 可适用 于具有较小散热及噪声较小的机拒的通风和降噪中。
实施例八

实施九
图 9为本发明实施例九提供的通风降噪系统的主视图。 与上述图 8A 所示实施例中机拒不同的是， 本实施例中的两个机拒的两侧分别设置有进 风口和出风口，其中两机拒之间设置有如图 7A ~图 7B所示的通风降噪装 置 206, 而在两机拒的另外一侧， 则设置有如图 1A所示的通风降噪装置 207。 具体地， 如图 9所示， 两个机拒 106的两侧分别设置有进风口和出 风口， 两个机拒 106之间设置有通风降噪装置 206; 机拒 106的另一侧设 置有通风降噪装置 207, 其中， 通风降噪装置 206可作为两个机拒 106共 用的进风装置， 通风降噪装置 207作为两个机拒 106的出风装置， 或者， 也可将通风降噪装置 206作为两个机拒 106共用的出风装置， 通风降噪装 置 207作为两个机拒 106的进风装置， 从而保证机拒的通风和降噪需要， 可满足机拒具有较大散热和降噪需求。

上述本发明各实施例中， 在通风降噪装置的通风模块的第一通风口以 及第三通风口内均设置空气驱动装置 2, 用于加快空气在机拒内的流通， 以提高外界冷风进入机拒内的速度， 以及提高机拒内热风排出机拒的速 度， 这样， 在安装通风降噪装置时， 可不需要考虑机拒是否安装空气驱动 装置， 只需要在通风装置上设置空气驱动装置， 即可满足机拒的通风量需 要。
其中， 上述的空气驱动装置 2具体可以是风扇等装置， 以驱动空气向 一定方向加速流动。 由于空气驱动装置在工作时会产生噪声， 因此， 空气 驱动装置安装在与机拒的通风口连通的第一通风口或第二通风口处， 使得 机拒运行时， 空气驱动装置产生的噪声会被通风模块的风道所吸收。
本领域技术人员可以理解的是， 上述本发明各实施例中， 通风降噪装 置的通风模块内也可不设置空气驱动装置， 而是可以在机拒相应的通风口 处设置空气驱动装置， 这样， 通风模块内可不必考虑安装空气驱动装置所 需的结构， 且也不需要在通风模块上考虑设置控制空气驱动装置的电路 等， 在使用时， 只需要将通风降噪装置安装在机拒上即可。 在使用时， 可 通过机拒上设置的控制电路来控制其上设置的空气驱动装置的工作， 同样 可以加速空气进出机拒的速度，保证机拒的通风量，满足机拒的降温需要。
本发明各实施例中， 也可在通风降噪装置的部分通风模块的第一通风 口或第三通风口内设置空气驱动装置， 可在保证机拒内空气流动速度， 确 保机拒冷却所需通风量的同时， 可利用较多的通风模块来对机拒运行中产 生的噪声进行降噪处理， 最大程度减少机拒运行中产生的噪声对外界环境 的影响。 下面将以具体的实例进行说明。

上述本发明各系统实施例中， 根据机拒设置的进风口和出风口的位 置， 可合理安排通风降噪装置中各通风模块的第二通风口的位置， 以便于 作为冷风进入的第二通风口和作为热风排出的第二通风口可位于机拒的 不同侧， 避免冷风和热风混合而降低机拒的降温效果。
本发明各系统实施例中， 机拒内可根据需要设置合适的气体流通通 道， 以便与设置在机拒外部的通风降噪装置配合， 使得机拒内空气流通顺 畅， 有效对机拒内产生的热量进行热交换， 提高机拒的散热效果。
