Of course, in other embodiments, the fifth stopping device 7 and the sixth stopping device 8 may also be butterfly valves.

The working principle of the inserting frame CDU system is as follows:

experiments or calculations are performed first to obtain preset flow values L0 of the heat exchange medium and preset temperature values T0 at the output end of the power assembly 32, which are required by the server correspondingly, at different environmental temperatures.

The temperature and humidity sensor 34 measures the real-time temperature and humidity of the inserting frame, and then measures the environment dry bulb temperature, so that the real-time environment dew point temperature T2 can be obtained. And determining values of the corresponding flow preset value L0 and the corresponding temperature preset value T0 according to the experiment or calculation result by combining the cooling amplitude required by the server in real time.

And judging whether the temperature reduction range required by the server in real time is larger than a preset temperature reduction range or not, if so, starting the fan 11 and the circulating pump 321. For example, the temperature reduction range required by the server in real time at present is 7 ℃, the preset temperature reduction range is 3 ℃, that is, at this time, the PID controller may determine and turn on the fan 11, and then turn on the circulating pump 321.

Through first medium temperature sensor 322, measure the real-time temperature T1 of the heat transfer medium of power component 32's output end department, judge whether satisfy T1 < T2+ k, wherein, k is the positive number, then there is the condensation risk at the outer wall of indoor pipeline, because the environment at server place does not allow the appearance liquid, so get into the condensation mode of preferentially preventing, otherwise get into the refrigeration mode.

Preferential anti-condensation mode: and the PID controller performs PID adjustment on the running power of the fan 11, the running power of the circulating pump 321 and the opening degree of the flow control device 13 until T1 is more than or equal to T2+ k, removing the condensation risk and entering a refrigeration mode.

A refrigeration mode: the PID controller performs PID adjustment on the operating power of the fan 11, the operating power of the circulating pump 321, and the opening degree of the flow control device 13 until T1 is equal to or less than T0 and the real-time flow L1 of the heat exchange medium is equal to or greater than L0, that is, the heat exchange medium in the server heat exchange module 2 can meet the requirement that the temperature of the server is reduced to the required temperature range.

When the server needs a large cooling range, the plug-in frame CDU system can quickly cool the server, and when the server needs a small cooling range, the plug-in frame CDU system can slow down the cooling rate to approach the target temperature. Therefore, the energy consumption is reduced while the cooling requirement of the server is ensured.

In addition, the working principle of the inserting frame CDU system also comprises control over automatic liquid supplementing. Specifically, the PID controller determines whether liquid injection is required according to the real-time pressure value of the heat exchange medium measured by the third pressure sensor 5. When the real-time pressure value is lower than the preset liquid injection pressure and the first time duration is kept, the liquid injection pump 313 is turned on to inject the heat exchange medium into the plug-in frame CDU system. Specifically, the liquid injection pump 313 runs for a second time period, stops for a third time period, runs for the second time period, stops for the third time period, and so on, so that intermittent liquid injection is realized, and the pressure after liquid injection is closer to the target pressure value. When the value fed back by the third pressure sensor 5 is greater than or equal to the target pressure value, the operation of the liquid injection pump 313 is stopped, and the automatic liquid supplementation is finished. This insert automatic fluid infusion function of frame CDU system can reduce artifical input, guarantees the stability of system's operation.
