In the present embodiment, the detection system includes a deionization unit 3, at least two conductivity detection units 7, and a display terminal device 8. Specifically, to ensure the cooling water insulation of the equipment to be cooled, such as high-voltage high-power devices, at high voltage, the water cooling apparatus is equipped with a deionization unit 3. The deionization unit 3 includes deionization chambers partitioned by an ion exchange resin membrane 9 built therein, the ion exchange resin membrane 9 being made of ion exchange resin. And the both sides of deionization room are equipped with inlet tube 1 and outlet pipe 2 respectively, and inlet tube 1 communicates with delivery pipe 4 that provides the raw water, and outlet pipe 2 passes through cooling tube 5 and sample header tank 6 intercommunication.

In a further preferred embodiment of the present invention, as shown in fig. 1, the conductivity sensor is covered with a detachable electromagnetic interference shielding net.
Because the conductivity sensor will also have abnormal detection result when being influenced by the surrounding magnetic field, in order to eliminate whether the problem of abnormal conductivity is influenced by the magnetic field, in this embodiment, a detachable electromagnetic interference shielding net (not shown in the figure) is covered outside the conductivity sensor, the magnetic field possibly existing around the conductivity sensor is blocked by using the characteristic that the electromagnetic interference shielding net can shield the magnetic field, and then whether the conductivity value is recovered to a normal value is observed, if so, the reason of abnormal conductivity caused by the magnetic field of the conductivity sensor can be judged.

Since the conductivity can be influenced by the purity of water quality, the conductivity is lower when the water quality is better, and the insulation of cooling water of equipment to be cooled, such as a high-voltage high-power device, under high voltage is ensured. Therefore, in this embodiment, the detection system further includes a precision filter 10 disposed between the water outlet pipe 2 and the cooling pipe 5, for filtering the deionized water flowing out from the deionization unit 3, so as to improve the purity of the raw water.

Since the conductivity is affected by the temperature, the lower the conductivity, and the insulation of the cooling water of the equipment to be cooled, such as a high-voltage high-power device, under high voltage is ensured. Therefore, in the present embodiment, the detection system further includes a temperature detection device (not shown in the figure) communicating with the inside of the cooling pipe 5. The temperature detection device includes a temperature sensor (not shown) and a temperature transmitter (not shown). Specifically, the temperature sensor is arranged on the inner wall of the cooling pipe 5, and one end of the temperature sensor is provided with a second probe which is in contact with the deionized water in the cooling pipe 5 and is used for collecting the temperature parameter of the deionized water in the cooling pipe 5.

When only one conductivity detection unit 7 is adopted to detect the conductivity value, if the reason that the detection result is abnormal is caused by the conductivity detection unit 7, for example, the detection result is wrong due to the damage of the conductivity detection unit 7, the misjudgment can be avoided, the difficulty in eliminating the abnormal problem is increased, and the workload of workers is increased.
