Abstract
A fan type temperature control method and device are provided. The device includes a fan unit including a plurality of fans and cooling an apparatus to be cooled, power supplies (v1,v2) supplying power for the fans in the fan unit, and a fan control unit which controls the fans as follows: when temperature t of the apparatus is lower than critical temperature t1 of a first temperature detect switch (k01), all fans stop; when t is higher than t1 and lower than critical temperature t2 of a second temperature detect switch (k02), all fans rotate at half speed; when t is higher than t2 while lower than critical temperature t3 of a third temperature detect switch (k03), a first fan part (M1) rotates at full speed and a second fan part (M2) stops; when t is higher than t3, all fans rotate at full speed.
