1. An enclosed flash-evaporation heat exchanger, comprising:
an enclosed housing to prevent an outdoor air from entering the enclosed housing, wherein a negative-pressure fan is provided on the enclosed housing, and the negative pressure fan is configured to form a negative-pressure environment inside the enclosed housing,
wherein a water atomization device is provided on one side of the enclosed housing, and the negative-pressure fan is provided on another side of the enclosed housing; a heat exchanging device is provided inside the enclosed housing, a high-temperature medium is flowing through the heat exchanging device to be cooled and the heat exchanging device is located between the water atomization device and the negative-pressure fan; a first static pressure chamber is formed between the negative-pressure fan and the heat exchanging device, a second static pressure chamber is formed between the water atomization device and the heat exchanging device, a negative-pressure environment in the second static pressure chamber is formed by the negative-pressure fan, and the water atomization device is arranged toward a direction where the heat exchanging device is located and is configured to spray a atomized water into the second static pressure chamber to evaporate the atomized water into a vapor to cool the high-temperature medium.
