[0002] Air volume is a key factor affecting the heat dissipation of electronic equipment. How to efficiently distribute the air volume affects the overall heat dissipation effect of the electronic equipment. Common measures to adjust the air volume include adjusting the fan speed and adjusting the size of the air inlet and outlet of the electronic equipment. Adjusting the fan speed will affect the overall increase or decrease of the air volume of the entire electronic equipment module, and cannot solve the problem of uneven air volume distribution inside the electronic equipment. The measures to adjust the size of the air inlet and outlet of the electronic equipment are usually to design a fixed air inlet and outlet structure, which cannot dynamically adjust the air volume distribution of the internal modules of the electronic equipment.

The utility model is a modular data center with an air volume adjustment function. The temperature sensor monitors the internal temperature in real time. The staff turns on the air cooler according to the displayed temperature when the temperature is too high, inputs the cold air through the air inlet pipe, and then controls the venturi metering valve through the control key to adjust the air volume. The cold air is then ejected by the nozzle. In summary, the air volume adjustment still cannot achieve the adaptive adjustment function. Summary of the Invention
