The water supply assembly is connected to the pipe assembly through a hose, and the pipe is fixed to the pipe bracket 34, and in order not to change the original structure, the pipe bracket 34 is supported on the steel structure 33 of the original cooling fin 32 through welding or bolting. The branch pipes are distributed below different areas of the cooling fins 32 of the air cooling fan 31, and the determination of the distance between the branch pipes and the distance between the nozzles needs to ensure that atomized jet can uniformly cover all fin inlet environments according to the parameters such as the jet angle, the distance, the area and the like of the nozzles. A plurality of pumps in the pump group are respectively communicated with a main pipe for controlling pipelines in each region, and an electric valve is arranged at the end of a high-pressure water inlet of the pipeline.

The high-pressure pump set is arranged on the chassis, is connected with the water supply assembly through a high-pressure hose, and monitors the water pressure in the pipe in real time through a pressure gauge.
The monitoring control system 3 includes an ambient temperature sensor 32, a humidity sensor 31, a wind speed sensor 33, a wind direction sensor 34, a fin temperature sensor 35 (or a fan rotation speed sensor, which can directly or indirectly obtain the actual working state of the load), a hard disk for storing control data, and a CPU for processing the data input from each sensor and transmitting control signals.

The pipeline is also provided with a water outlet, so that the medium can be emptied when the pipeline is not needed for a long time.
Acquisition of control data
The fin is mainly based on ventilation to improve the radiating effect, but simultaneously, when wind force is too big, also probably influence the drop point of water smoke, makes its comprehensive cooling effect be difficult to define, if last lets in the cooling water this moment, will probably waste partial water resource. For this purpose, the following method is adopted for standardized measurement, and a standardized curve is generated according to the measurement result, so that an optimal cooling scheme under different wind conditions is realized.
In the experimental stage, environmental parameters including parameters such as fin temperature, humidity, wind speed, wind direction and the like are collected under the full load condition of load equipment by simulating different seasons and layout heights. The influence factors of seasons mainly comprise temperature and humidity, and the experiment takes humidity as a main influence factor because the humidity can influence the heat conductivity coefficient of air. Different laying heights can generate wind direction and wind speed (wind force) change, wherein the wind speed is taken as a main influencing factor.
The actual working conditions of the fins are simulated in a standardized parameter manner by adopting a single rotatable fin group with a heating device.
Selection of fin size: the high-pressure nozzle can just cover the whole fin group by adopting the same spraying distance (in actual use).
Setting a heating device: the heating power of the heating device is ensured to be larger than the heat dissipation efficiency of the heat dissipation fins, and the temperature threshold T0 can be set. To simulate heating of the load.
Setting of the injection quantity of the nozzle: the fins of the spray mist can drop linearly from the temperature threshold. (neglecting the optimum air-water ratio) at the same time, the fan-shaped spray area of the nozzle should cover the fin group just right above the fin center line, and the nozzle should be located right above the fin center line, thereby excluding the influence of wind direction on the heat radiation effect.
Humidity f (w) control curve: and (3) starting the heating device, closing the heating device after the temperature of the fin reaches a threshold value T0 (the temperature is lower than T0, the heating device is not started), under the condition of closing the fan (under the windless condition), taking 1% as an increment, measuring the time T0 when the temperature of the fin is naturally cooled to the room temperature T1 from the temperature threshold value T0 under the environment with adjustable humidity w, and generating a comparison curve f0 (w).
Humidity/wind speed f (w/v) control curve: starting a heating device, closing the heating device after the temperature of the fin reaches a threshold value T0 (the temperature is lower than T0, the heating device is not started), gradually increasing the wind speed v of a fan by taking 0.5m/s as an increment, matching different humidity w conditions (taking 1% as an increment), measuring the time T1 when the temperature of the fin is naturally cooled to the room temperature T1 from the temperature threshold value T0, and generating a comparison curve f1 (w, v).
Humidity/wind speed f (w/v) simulation curve: starting a heating device, keeping constant temperature after the temperature of the fin reaches a threshold value T0 (the temperature is lower than T0, the heating device is immediately started), starting an atomizing nozzle, gradually increasing the wind speed v of a fan with 0.5m/s as an increment, matching different conditions of humidity w (with 1% as an increment), measuring the time T2 when the temperature of the fin is cooled to a set temperature T2 from the temperature threshold value T0, and generating a simulation curve f2 (w, v).
And (3) screening results, fitting f1 (w, v) and f2 (w, v), extracting values with the similarity of >90%, wherein the similarity is high, which means that the influence of spraying water mist on the cooling effect is small, and establishing a control data set from the extracted data. If the humidity, wind values of the environment fall within the data set, no water mist is needed for cooling.
