The utility model relates to a surface air cooler, a fan coil and a data center air conditioning system. The surface air cooler comprises a water inlet collecting pipe, a water outlet collecting pipe and a plurality of heat exchange pipes, and each heat exchange pipe is provided with a liquid inlet communicated with the water inlet collecting pipe and a liquid outlet communicated with the water outlet collecting pipe. And a height difference exists between every two of the liquid inlet, the liquid outlet and the water drain valve. When the surface air cooler is in a working state, the water drain valve is in a closed state, and under the action of external pressure, the heat exchange medium exchanges heat with air outside the heat exchange pipe in the process of flowing from bottom to top in the heat exchange pipe. When the surface air cooler is in a non-working state, the water drain valve is in an open state, residual heat exchange media in the heat exchange pipes can spontaneously flow downwards to the liq
