Abstract

The invention discloses a temperature control device and a variable-speed fan. The temperature control device comprises an infrared thermometry circuit, a fan control circuit and a variable frequency motor, wherein the infrared thermometry circuit is arranged on a radiation path of a processor and used for obtaining the real-time temperature of the processor according to infrared radiation signals of the processor; the fan control circuit is connected with the infrared thermometry circuit and used for generating rotary speed control signals according to the real-time temperature; and the variable frequency motor is connected with the fan control circuit and used for rotating under the triggering of the rotary speed control signals. The technical problem of a poor heat radiation effect of an existing variable-speed fan is solved.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a temperature control device and a variable-speed fan. Background technique [0002] In the prior art, the four-pin automatic speed-adjusting fan can realize speed regulation by measuring the different states of the chip’s operating voltage, but it requires manual adjustment by the user, which is not smart enough and difficult to achieve the best heat dissipation effect. In order to solve this problem, the four-pin A temperature probe is added to the automatic speed-adjusting fan, but after adding the temperature probe, the temperature probe must be in contact with the heat sink. Due to poor heat conduction and temperature lag caused by dust, the cooling effect of the four-pin automatic speed-adjusting fan is also poor. A PWM temperature-controlled fan is also provided in the prior art. The PWM temperature-controlled fan can output a pulse width modulation signal according to...
