[0036] When the above-mentioned air handling system for the operating room is used, the working principle is as follows: the air carrying the heat of the data server is sucked into the hot air pipe module through the air suction layer module for preliminary cooling, and then transported to the heat exchanger plate for cooling. The cold air after the secondary cooling is transmitted from the air outlet of the hot air pipe module to the air duct, and the blowing layer module blows the cold air into the data server located in the heat-insulating wall panel, which does not occupy the space of the computer room and is convenient for maintenance. At the same time, it drives the heat load to be transmitted upward in time to reduce the thermal resistance, and also avoids the occurrence of local heat concentration areas, ensuring the consistency of the cooling performance in various places in the space, so that the working environment of several data servers in the space is the same, and the reliability of the data center performance is improved;

[0037] In addition, a buffer tube is provided between two adjacent heat dissipation pipes having a plurality of air inlet openings and connected through a second bent tube. When there is an air pressure difference and a heat load difference between the heat dissipation pipes, the buffer tube is adjusted to overcome the defect of uneven air volume of multiple air outlets of the hot air pipe module in the heat insulation wall panel due to factors such as the arrangement of the data server and the difference in the working state of the suction fan of the suction layer module, thereby improving the consistency of the cooling efficiency of the hot air pipe module and the heat exchanger plate in each area, thereby improving the overall comprehensive cooling efficiency;

[0038] In addition, the temperature information is sent to the controller through the temperature sensor installed on the hot air pipe module. The controller determines the matching between the temperature information and the set threshold range, and selectively controls the fan unit to be turned on or off;

[0039] Avoid the situation where the heat generated by the server in different working states is different, and there are different cooling requirements, and the cooling components cannot work in time to match the different cooling requirements, resulting in low cooling efficiency, poor cooling effect, or excessive energy consumption and excess resources of the cooling components. Selectively increase or reduce the cooling and cooling links to match the changing cooling requirements, improve the utilization rate of each cooling component, improve the overall cooling efficiency of the system, and reduce energy consumption.
