具体实施方式
下面，结合附图以及具体实施方式，对本发明做进一步描述，需要说明的是，在不相冲突的前提下，以下描述的各实施例之间或各技术特征之间可以任意组合形成新的实施例。
如图1-3所示，本发明实施例提供的冷却装置1，用于冷却液体，包括进液组件11、风冷散热组件12、液冷散热组件13、出液组件14及控制装置15；进液组件11包括进液管路111及与进液管路111连接的第一进液支路112和第二进液支路113，出液组件14包括出液管路141；第一进液支路112通过风冷散热组件12与出液管路141连通；第二进液支路113通过液冷散热组件13与出液管路141连通；控制装置15包括控制模块151以及与控制模块151电连接的信号采集模块152、执行模块153和电源模块154；信号采集模块152用于采集冷却液体的温度信息、环境温度信息和液位信息并将该温度信息和液位信息发送到控制模块151，控制模块151用于根据该温度信息和液位信息控制执行模块153启动风冷散热组件12和/或液冷散热组件13。冷却液体用于对数据中心柜进 行散热，水冷散热方式效果持续稳定，可在不同环境温度下实现稳定冷却需求，但是能耗高；风冷散热方式能耗低，但受环境温度影响较大，当温度超过允许值时，风冷散热方式无法满足对冷却液体的冷却需求。本实施例提供的冷却装置1的风冷散热组件12和液冷散热组件13并联连接，信号采集模块152检测冷却液体的温度信息和液位信息，同时采集环境温度信息，当环境温度和冷却液体的温度在允许范围内时，控制模块151控制开启风冷散热组件12，当环境温度或者冷却液体温度超过允许范围时，控制模块151控制开启液冷散热组件13，以此达到节能和稳定的效果。
作为优选的实施方式，风冷散热组件12包括风冷散热器121，第一进液支路112通过风冷散热器121与出液管路141连通；液冷散热组件13包括依次连接且组成回路的冷水机131、换热器132及冷冻水循环泵133，第二进液支路113通过换热器132与出液管路141连通；第一进液支路112与进液管路111之间连接有第一电动阀118，第二进液支路113与进液管路111之间连接有第二电动阀119，第一电动阀118和第二电动阀119均与执行模块153连接。执行模块153通过切换第一电动阀118和第二电动阀119控制冷却液体流经风冷散热器121或者换热器132。
进液组件11还包括设置于进液管路111上的两个供液泵114及第一压力传感器115，第一压力传感器115与两个供液泵114连接，信号采集模块152用于采集第一压力传感器115的第一压力信息并发送到控制模块151，控制模块151用于根据第一压力信息和液位信息控制执行模块153启动供液泵114。信号采集模块152将第一压力传感器115的第一压力信息反馈到控制模块151，执行模块153与变频器(图中未示出)连接，执行模块153控制变频器调整输入频率，维持整个冷却装置1供给压力稳定，可以根据冷却液体的流量负荷自动调整变频 器的输入频率和功率，达到最大节能效果。两个供液泵114分别作为主用和备用设备，控制模块151根据第一压力信息判断供液泵114是否出现故障，如果供液泵114无法正常工作，信号采集模块152采集的第一压力信息出现异常，以此作为判断供液泵114出现工作的依据，当主泵出现故障，执行模块153会自动切换主泵和备用泵的管路阀门，启动备用泵工作，在备用泵运行期间，及时排除主泵故障，操作系统切换到主泵工作。
进液组件11还包括设置于进液管路111一端的进液腔116，进液腔116内设置有第一液位传感器1161及第一温度传感器1162，第一液位传感器1161及第一温度传感器1162均与信号采集模块152连接。信号采集模块152采集第一液位传感器1161的液位信息并发送到控制模块151，当控制模块151检测到进液腔116内的液位达到预设值时，执行模块153控制供液泵114启动。控制模块151根据第一温度传感器1162的温度信息及环境温度控制执行模块153启动风冷散热组件12或液冷散热组件13。进液腔116内还设置加热器1163，当冷却液体稳定低于10度时，对冷却液体进行加热，当冷却液体稳定达到10度时，停止加热，从而可以保证整个冷却装置1在合理的温度范围内工作，保证系统的稳定性。进液腔116与供液泵114之间还设有第一过滤器117，第一过滤器117的数量为两个，两个第一过滤器117分别与两个供液泵114连接，第一过滤器117对冷却液体进行初级过滤，保证系统稳定运行。
出液管路141上设置有两个第二过滤器142及与第二过滤器142连接的第二压力传感器143，信号采集模块152用于采集第二压力传感器143的第二压力信息并发送到控制模块151，控制模块151用于根据第二压力信息控制执行模块153启动第二过滤器142。第二过滤器142用于对冷却液体进行次级过滤，两个第二过滤器142分别作为主用和备用，两个第二过滤器142各连接一个第三电 动阀144，当第二压力传感器143的第二压力信息超过设定值时，说明正在使用的第二过滤器142出现故障，需要维修更换，执行模块153通过切换两个第三电动阀144启动另一个第二过滤器142工作，同时停止正在使用的第二过滤器142。其中一个第二过滤器142作为主过滤器，主过滤器出现故障时，备用过滤器工作，主过滤器更换之后，操作系统切换到主过滤器，定期更换备用过滤器。进一步地，出液管路141上设置还有流量传感器145，流量传感器145与信号采集模块152连接，控制模块151还根据流量传感器145反馈的信息控制启动水冷散热方式或风冷散热方式。
作为优选的实施方式，液冷散热组件13还包括冷冻水箱134，冷冻水箱134连接于冷冻水循环泵133和冷水机131之间，冷冻水箱134内设置有第二液位传感器1341，第二液位传感器1341与信号采集模块152连接，控制模块151根据第二液位传感器1341的信息控制冷冻水循环泵133的工作状态。冷冻水循环泵133与换热器132之间连接有流动开关135，用于控制冷冻水回路的流通和闭合。液冷散热组件13还包括补水装置(图中未示出)，用于对冷水机131补水。换热器132为板式换热器，板式换热器包括第一换热通道1321和第二换热通道1322，第一换热通道1321与进液管路111连接，第二换热通道1322与冷水机131连接。冷却液体和冷冻水通过第一换热通道1321和第二换热通道1322交换热量，从而达到降低冷却液体温度的效果。
作为优选的实施方式，风冷散热器121包括多个散热风机1211，根据冷却液体的温度开启合适数量的散热风机，达到降低能耗的目的。当环境温度或者冷却液体温度超过设定值时，执行模块153控制风冷散热方式切换到水冷散热方式，液冷散热组件13启动，风冷散热组件12关闭。当环境温度或者冷却液体温度下降到设定值时，风冷散热组件12开启，液冷散热组件13关闭，控制 模块151根据冷却液体温度判断开启零组散热风机、一组散热风机、两组散热风机或多组散热风机等，每种工作状态对应一个冷却液体温度。例如，当供给冷却液体温度较低时，风冷油散热器121工作在零组散热风机的状态，当冷却液体吸收服数据中心柜的热量缓慢升温超过了零组散热风机的工作上限温度，系统就会启动一组散热风机，当供给冷却液体的温度继续上升超过了一组散热风机工作设定温度上限，执行模块153就会开启第二组散热风机，使风冷散热器121工作在最大负荷状态，如果冷却液体的温度继续升高超过了风冷散热器121最大冷却负荷工作状态下的最高值，执行模块153就会切换阀门，开启液冷散热组件13；依次类推，当冷却液体温度持续下降时，执行模块153也会逐级关闭散热风机1211，以降低能源消耗。
如图3所示，本发明实施例提供的液冷散热系统，包括依次连接的储油箱2、重力淋油装置3、回油管路4及上述的冷却装置1，储油箱2与出液管路141连接，回油管路4与进液管路111连接，冷却液体为绝缘硅油，经过冷却装置1冷却的绝缘硅油在油泵的驱动下，从储油箱2经过重力淋油装置3冷却数据中心柜，吸收数据中心柜的热量，然后依靠重力和回油管路4的虹吸作用，经过进液管路111流到进液腔116，控制装置15根据冷却液体的温度和环境温度信息控制绝缘硅油流经第一进液支路112或者第二进液支路113，同时开启相应的风冷散热组件12或者液冷散热组件13，被冷却的硅油进入储油箱2，继续冷却数据中心柜，从而完成一个循环，以达到节能和稳定的目的。作为优选的实施方式，第一压力传感器115将采集到的压力信息反馈到变频器，变频器通过PID控制方式驱动油泵，保证油泵出口恒压运行，进一步起到有效节能的作用。
本发明提供的冷却装置和液冷散热系统，控制装置根据冷却液体的温度和环境温度控制启动风冷散热或者水冷散热，降低整体能耗，且保证系统的稳定 性。
上述实施方式仅为本发明的优选实施方式，不能以此来限定本发明保护的范围，本领域的技术人员在本发明的基础上所做的任何非实质性的变化及替换均属于本发明所要求保护的范围。
