Description

一种流动服务器机柜 技术领域
本发明涉及一种流动服务器机柜。
背景技术
计算机芯片在高速运转过程中会产生大量热量，随着计算机技术和集成电路制造技术的快速发展，芯片单位面积所散出的热量愈来愈高。如果计算机服务器的芯片持续在高温下工作，会造成内部电路短路或断路，最后损坏。为避免热量累积导致温度过高而损坏芯片，合理的散热系统是必不可少的。
目前，服务器机柜大多是设置在室内，通过中央空调控制室内的温度，保证计算机服务器的能够正常的散热。然而，对于流动服务器机柜来说，其一般是设置再室外，采用空调来进行来控制柜体内的温度十分耗费电能。
发明内容
有鉴于此，本发明的目的在于提供一种散热效果优异，节能的流动服务器机柜。
本发明为解决其技术问题而采用的技术方案是：
一种流动服务器机柜，其包括柜体，所述柜体内设置有外循环通道，所述外循环通道包括沿着气流方向依次设置的进气口、进气通道、服务器室、排气通道和排气口，所述的进气口处设置有开口大小可调的进气阀，所述的排气口处设置有开口 大小可调的排气阀，所述排气通道内还设置有用于将其中的空气从所述排气口排出的风机，所述柜体内还设置有能够将进气通道和排气通道直接连通的回流通道，所述回流通道内设置有控制其导通和关闭的回流阀，所述的进气通道、服务器室、排气通道和回流通道构成一内循环通道，所述的进气阀、排气阀和回流阀均开启时，内循环通道和外循环通道内的气流同时流通，所述排气通道内设置有检测气温的第一检测器，所述柜体上设置有能够检测柜体外部气温的第二检测器。
作为优选地，所述进气通道为设置在所述服务器室右侧的垂直通道，进气通道的下端与所述服务器室连通，所述进气口设置在进气通道上端的侧壁上，所述排气通道为设置在所述服务器室右侧的垂直通道，排气通道的下端与所述服务器室连通，所述排气口设置在排气通道上端的侧壁上，所述回流通道设置在服务器室的上方，回流通道的两端分别与进气通道的上端和排气通道的上端连通。
作为优选地，所述进气通道与服务器室之间设置有蒸发式冷却器。
作为优选地，所述蒸发式冷却器包括透气的棉布芯和设置在所述棉布芯上方的水管，所述水管上设置有能够朝着棉布芯喷淋水雾的喷淋头。
作为优选地，所述服务器室内设置有能够检测空气湿度的第三检测器，所述第三检测器为湿度传感器或温湿度传感器。
作为优选地，所述蒸发式冷却器与进气口之间的气流通道 内设置有用于除尘的过滤网。

具体实施方式
下面将结合附图，对本发明实施例中的技术方案进行清楚、完整地描述。
参照图1至图4，一种流动服务器机柜，其特征在于其包括柜体1，柜体1内设置有外循环通道，外循环通道包括沿着气流方向依次设置的进气口14、进气通道11、服务器室12、排气通道13和排气口15，进气口14处设置有开口大小可调的进气阀2，排气口15处设置有开口大小可调的排气阀3，排气通道13内还设置有用于将其中的空气从排气口15排出的风机4，柜体1内还设置有能够将进气通道11和排气通道13直接连通的回流通道16，回流通道16内设置有控制其导通和关闭的回流阀5，进气通道11、服务器室12、排气通道13和回流通道16构成一内循环通道，进气阀2、排气阀3和回流阀5均开启时，内循环通道和外循环通道内的气流同时流通。排气通道13内设置有检测气温的第一检测器61，第一检测器61为温度传感器或温湿度传感器；柜体1外表面设置有能够检测柜体1外部气温的第二检测器62，第二检测器62为温度传感器或温湿度传感器。
为了实现闭环自动控制，还包括中央处理器，中央处理器根据第一检测器61测得的温度值能够调节进气阀2的开口大小、排气阀3的开口大小以及风机4的转速，根据第二检测器 62测得的温度值能够控制回流阀5的启闭。
使用本发明时，计算机服务器9安装在服务器室12内。风机4的出风口正对着排气阀3，在风机4的作用下，外部的空气能够从进气口14进入，依次经过进气通道11、服务器室12和排气通道13，将服务器室12内的热量带出，最终从排气口15排出。由于排气通道13位于服务器室12的下游，因此排气通道13内的气温即可反映服务器室12内服务器的温度。
本发明的控制方式是：当柜体1外部温度在预设范围内，回流阀5完全关闭，进气阀2和排气阀3开启，风机4开启，进气阀2的开口大小、排气阀3的开口大小以及风机4的转速根据排气通道13内的温度进行控制，此时柜体1内仅有外循环，柜体1内的气流路线如图1所示。当柜体1外部温度高于预设值时，回流阀5完全关闭，进气阀2和排气阀3开口加大，风机4转速加快，此时柜体1内仅有外循环，柜体1内的气流路线如图1所示。当外部温度低于预设值时，回流阀5开启，进气阀2和排气阀3的开口减小，风机4转速减慢，此时柜体1内外循环和内循环同时进行，避免服务器室12内的气温过低，柜体1内的气流路线如图2所示。当外部温度和排气通道13内的气温均低于预设值时，回流阀5开启，进气阀2和排气阀3关闭，风机4停机，此时柜体1内仅有内循环，柜体1内的气流路线如图3所示。综上，本发明能够根据实际的气温情况，灵活应变，保证控制服务器室12内的气温始终保持在一个合理的范围，散热效果优异，和采用空调器进行散热的方案相比，十分节能。
本实施例中，进气通道11为设置在服务器室12右侧的垂直通道，进气通道11的下端与服务器室12连通，进气口14设置在进气通道11上端的侧壁上，排气通道13为设置在服务器室12右侧的垂直通道，排气通道13的下端与服务器室12连通，排气口15设置在排气通道13上端的侧壁上，回流通道16设置在服务器室12的上方，回流通道16的两端分别与进气通道11的上端和排气通道13的上端连通。这样的设计的好处是：当风机4开启时，在风机4的作用下，进气通道11上端的气压比排气通道13上端的气压略小，通过回流通道16将进气通道11的上端和排气通道13的上端直接导通，能够实现气流的内循环和外循环同时进行。
为了进一步增强本发明的冷却性能，进气通道11与服务器室12之间设置有蒸发式冷却器7。当外部的气温过高时，可以开启蒸发式冷却器7，能够对将由进气通道11流入服务器室12的的空气降温，增强散热效果。
参照图3，本实施例中，蒸发式冷却器7包括透气的棉布芯71和设置在棉布芯71上方的水管72，水管72上设置有能够朝着棉布芯71喷淋水雾的喷淋头73。
为了避免服务器室12内的湿度过高，服务器室12内设置有能够检测空气湿度的第三检测器63，第三检测器63为湿度传感器或温湿度传感器。蒸发式冷却器7开启一段时间后，若服务器室12内的湿度达到上限值，中央控制器则会发出指令，将蒸发式冷却器7关闭。当服务器室12内的内的湿度低于下限值 时，中央控制器则又会发出指令，将蒸发式冷却器7打开。
为了保持服务器室12内的清洁，避免空气中的灰尘进入其中，蒸发式冷却器7与进气口14之间的气流通道内设置有用于除尘的过滤网8。本实施例中，过滤网8固定在蒸发式冷却器7上朝向进气通道11的一侧。
以上仅为本发明的优先实施方式，只要以基本相同手段实现本发明目的的技术方案都属于本发明的保护范围之内。
