With such an arrangement, when any pipeline in the chilled water centralized distribution module 10 of the air conditioner in the data center fails and leaks water and flows into the water receiving tray 181, the frozen water in the water receiving tray 181 can be safely discharged outward through the drain pipe to avoid The water level in the water receiving tray 181 rises and enters the cabinets of the data center.

Specifically, a floor drain is provided at the bottom of the water receiving tray 181, and the drain pipe is connected to the floor drain to discharge the frozen water in the water receiving tray 181 through the floor drain and the drain pipe.

Moreover, in order to make the frozen water in the water receiving tray 181 be discharged outwards smoothly through the drain pipe, the drain pipe can be arranged obliquely, specifically, the water inlet of the drain pipe is higher than the water outlet, so that a vertical direction is formed between the water inlet and the water outlet. downhill slope.

The above is only a preferred embodiment of the present invention, and does not therefore limit the patent scope of the present invention. Under the inventive concept of the present invention, the equivalent structural transformation made by using the description of the present invention and the contents of the accompanying drawings, or direct/indirect use All other relevant technical fields are included in the patent protection scope of the present invention.
