Patent ID: 8594857

Claim:
A modulized heat-dissipation control method for a datacenter, applied to a rack of a datacenter, wherein the rack has multiple servers, each server is disposed with at least one central processing unit (CPU), the rack has a plurality of fan modules, and each of the fan modules corresponds to several of the servers, the heat-dissipation control method comprising: sensing all CPU temperatures in the rack; determining whether any one of the CPU temperatures is abnormal, and if yes, adjusting a flow of a first coolant; sensing inner temperatures of all the servers in the rack; and determining whether any one of the inner temperatures of the servers is abnormal, and if yes, determining whether a rotating speed of a fan module corresponding to the server has reached its maximum, and if yes, adjusting a flow of a second coolant, wherein the flow of the first coolant affects the CPU temperature, and the flow of the second coolant affects an air temperature at an inlet port of the fan module.
