附图说明
图1为本发明的系统原理图。
具体实施方式
以下结合附图对本发明的具体实施方式做进一步详述：
如图所示，一种集成桅杆综合冷却系统，用于三型雷达的各电源机柜、水冷机柜、信息处理机柜、伺服驱动机柜、通风除湿装置、伺服电机等发热设备的冷却。
系统包括一次冷却系统和二次冷却系统。一次冷却系统提供8±3℃的冷媒水，对雷达的部分负载冷却。二次冷却系统提供27±3℃的冷媒水对雷达部分特殊要求的负载进行冷却。
一次冷却系统以冷却塔1提供初步冷却后的海水作为冷却水，根据海水温度选择合适的制冷方式。冷却塔1的冷却水有供液泵2泵出，供液泵2前端安装有过滤器、压力传感器、温度传感器、电磁阀、压力表等附件，供液泵2的出口安装有压力表、止回阀、电磁流量传感器等附件，供液泵的出水分两个支路分别连接冷水机组3和海水换热器4，两个支路管路上分别串接有电磁阀，冷却水在冷水机组3的换热器换热或者在海水换热器4换热后由管道返回冷却塔1。水冷机组为压缩制冷机组，制冷剂在冷凝器中与冷媒水换热，将冷媒水降低到8±3℃后送入分水器5；或者冷却水在海水换热器4中与冷媒水换热，将冷媒水降温至8±3℃后送入分水器5。冷媒水为乙二醇。冷水机组3和海水换热器4与分水器5之间的管路上串接有止回阀、温度传感器以及电磁流量传感器。冷水机组3和海水换热器4不同时工作。当外界的海水温度低于5℃时，供液泵2与冷水机组3间的电磁阀关闭，供液泵2将低温海水送入海水换热器4中对冷媒水换热并输出至分水器5；当外界海水温度高于20℃时，供液泵2与海水换热器4间的电磁阀关闭，供液泵2将冷却塔1内的海水送入冷水机组3的换热器中，冷水机组4中的制冷剂液体在冷凝器中吸收冷媒水中的热量。高温高压的制冷剂气体在换热器中与海水进行热交换后冷凝为高压液体，经膨胀阀节流后进入冷凝器，完成制冷循环。同时通过压缩机运行数量的控制及单台压缩机能调的控制，从而控制冷却液的出水温度保持在8℃±3℃范围内。
8℃±3℃冷媒水在分水器5中集中并通过多条输入管路分别送至雷达各负载的换热器6内换热，带走热量，各输入管道上分别串接有电磁阀、压力传感器、温度传感器等附件，换热后的冷媒水回收管道送至集水器7内，各回收管道上分别串接有电磁阀压力传感器、温度传感器、电磁流量传感器等附件。同一负载对应的输入管道和输出管道间安装有动态压差平衡阀8。集水器中7的冷媒水经冷媒水泵9分别送回冷水机组3和海水换热器4的冷媒水通道内循环换热。冷媒水泵9的前端串接有除气器、压力传感器、温度传感器，冷媒水泵9的后端管道上串接有止回阀、电磁阀等，冷媒水泵9分两个支路连接冷水机组和海水换热器，两个支路上分别串接有电磁阀。
由于雷达的天线转台、伺服电机等负载需要27℃±3℃的冷媒水冷却，且冷媒水为水。由二次冷却系统提供。二次冷却系统包括水箱10、循环泵11、过滤器12、加热器13、板式换热器14，循环泵11自水箱10内抽取冷媒水，经过滤器12、加热器13后进入板式换热器14的冷媒水通道，在板式换热器14换热后经过管道送入负载的换热器中，在负载换热器换热后经管道回到水箱10中，完成循环。管道上均安装有压力传感器、温度传感器、止回阀、电磁阀等附件。板式换热器14的冷却水管道经管道串接在分水器5和集水器7之间，各管道上安装有电磁阀等附件，管道之间安装有动态压差平衡阀；分水器5中的8℃的乙二醇在板式换热器14中对冷媒水换热后回到集水器7。当冷媒水温度高于30℃时，板式换热器14的冷却水通道中中通入乙二醇，与冷媒水换热将其温度控制到27℃±3℃，此时加热器13关闭；当冷媒水的温度低于24℃时，板式换热器14的冷却水通道关闭，开启电加热13，将冷媒水温度加热调节至27℃±3℃；当冷媒水温度在24‐30℃之间时，板式换热器14的冷却水通道以及电加热13关闭，由循环泵11循环。
冷水机组的结构和空调附件及空调的控制系统均采取为空调行业内的常规手段，本方案中不做赘述。
