Data center

The invention relates to a data center. The data center inside a shipping container is internally provided with lower ventilation chambers and upper ventilation chambers. Air heated in the upper ventilation chambers leaves the same to enter a plurality of heat exchangers adjacent to the upper ventilation chambers. The air cooled through the heat exchangers forwards towards the lower ventilation chambers and enters the same. The data center comprises a plurality of brackets. Each bracket comprises a device receiving portion which is positioned between each open bottom portion in open communication with each lower ventilation chamber and each open top portion in open communication with each upper ventilation chamber. Fans in the brackets upwards suck the cooled air from the lower ventilation chambers to the open bottom portions of the brackets, blow up the cooled air to pass the device receiving portions so as to cool any computing devices received in the brackets and discharge the cooled air to the upper venti
