US 2012/0184199 A1 · FAN TYPE TEMPERATURE CONTROL METHOD AND DEVICE

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.

Dependent claims

A fan type temperature control method, comprising:

a step of low temperature processing, in which when temperature t of an apparatus to be cooled is lower than a preset first temperature t1, circuits of all fans remain disconnected, and all the fans stop;
a step of medium temperature processing, in which when the temperature t of the apparatus to be cooled is higher than the preset first temperature t1 and is lower than a preset second temperature t2, a voltage which is lower than a voltage of a power supply of a temperature control device is applied to all the fans, and all the fans rotate at a speed which is less than a maximum speed;
and
a step of high temperature processing, in which when the temperature t of the apparatus to be cooled is higher than a preset third temperature t3, the voltage of the power supply of the temperature control device is applied to all the fans, and all the fans rotate at full speed;
wherein, t1<t2≦t3.
