Abstract

The present invention discloses an electronic device and a fan assembly. The electronic device comprises a cooling device, a fan assembly and a control circuit; the fan assembly comprises a fan and a fan drive structure, and the fan drive structure comprises a power port and a first fan port different from the power port; the control circuit comprises a second fan port, and is connected with the fan drive structure through the first fan port and the second fan port; and the control circuit generates a fan revolution control instruction, and transmits the instruction to the fan drive structure through the first fan port and the second fan port, and the fan drive structure receives and executes the fan revolution control instruction to control the fan to carry out a corresponding revolution operation. According to the electronic device, by setting the first fan port, the technical problems of the complicated fan circuit design structure and the high cost of the electronic device in the prior art are solved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic device and a fan combination. Background technique [0002] With the continuous development of science and technology, the types and functions of electronic equipment are increasing day by day, and the enhancement of functions puts forward higher requirements for the heat dissipation of electronic equipment. The heat dissipation of electronic equipment usually uses a heat dissipation module composed of heat dissipation fins to conduct heat, and at the same time uses a fan to accelerate air convection to achieve the purpose of rapid heat dissipation. However, as the use time of electronic equipment increases, the dust in the environment where the electronic equipment is located will enter the interior of the electronic equipment and be adsorbed and accumulated on the heat dissipation fins and other components inside the electronic equipment. The more dust accumu...
