Description

抽屉式CDU 技术领域
本发明涉及服务器散热装置，特别涉及一种抽屉式CDU。
背景技术
服务器从它的发展趋势来看，由于其功能的集成越来越多，芯片发热功率越来越大，散热问题越来越严峻。传统的风冷已经不能解决现在服务器大功率所产生的热量问题。所以水冷将会是未来解决服务器散热问题的更好途径。而传统的风冷能耗高，占地面积大，而且随着服务器热流密度越来越大风冷已经满足不了服务器的散热需求。抽屉式CDU就很好的解决了这个问题，体积小，与服务器融为一体，高度只占7个U的空间。换热量高，能耗低，能大大的减少用电量，所以抽屉式CDU为目前水冷方案最可靠方案之一。
发明内容
本发明的目的在于提供一种抽屉式CDU，将热量集中到一起进行热交换，同时可以解决大功率发热的问题。
为解决上述问题，本发明采用的技术方案是：
抽屉式CDU包括依次通过管道连接的CDU进口、板式换热器、电磁阀、水箱、水泵、过滤器、CDU出口，还包括压力表、控制模块、温度变送器及抽屉；
压力表与水泵入水管道进行连接，置于抽屉外；
控制模块通过线路连接温度传感器、水泵、电磁阀，控制模块置于抽屉外；控制模块接收来自温度传感器所检测到的冷却液的温度，控制模块控制水泵的启动与停止、电磁阀的开与闭。控制模块分为自动模式、手动控制与停止模式三种，自动模式：自动运行模式：接受就地启动或远程启动指令后，液冷系统自动启动，并根据设定参数监控液冷系统的运行状况和检测系统故障。PLC自动控制冷却液温度，对液冷系统参数的超标及时的发出预警，当参数严重超标有可能影响服务器机柜运行安全时自动发出跳闸警报。主循环水泵、电动阀等由PLC根据实际工作条件进行自动控制。手动模式：在手动状态，水泵、电动三通阀可通过触摸屏操作。停止模式：该模式下所有用电设备停止工作。
所述温度变送器安装于板式换热器出水口；
所述板式换热器、电磁阀、水箱、水泵、过滤器、温度变送器集合于抽屉内。
为了更好的实现本发明，所述水泵采用冗余设计，一用一备，水泵是为系统提供动力，带动冷却液流经发热器件，带走发热器件的热量。
所述板式换热器是采用钎焊板式换热器。从服务器带来的热量会在这里进行热交换，使冷却液温度降低。
所述水箱容量3L可以储存冷却介质，缓冲压力。
本发明的设计原理在于：
内冷水通过分水器分配至各服务器单元，流经服务器各单元后，带走CPU、内存等发热器件的热量，回水通过水水换热器与外冷水完成热量交换，内冷水温度下降，回到水箱，经过水泵、过滤器进入下一循环。
本发明与现有技术相比，具有如下优点及有益效果：
本发明把柜式服务器与抽屉式CDU融合为一体，高度占7个U的空间，无泄漏点，具有安全可靠、维护便捷、结构紧凑小巧及高效散热的特点，能对液冷系统进行实施监控、操作和报警。
