Variable frequency control method for heat dissipation device of VR all-in-one machine

The invention provides a frequency conversion control method for a heat dissipation device of a VR all-in-one machine, the heat dissipation device comprises a control unit, a fan and a temperature detection unit, the fan and the temperature detection unit are connected with the control unit, and the temperature detection unit obtains the temperature of the VR all-in-one machine in real time and sends the temperature to the control unit; when the temperature of the VR all-in-one machine is larger than or equal to a first preset value, the control unit controls the fan to be started, and the frequency of the fan is changed according to the temperature of the VR all-in-one machine. Therefore, when the VR all-in-one machine is started, the fan can dissipate heat according to the actual temperature, so that the energy consumption is reduced, the cruising ability of the VR all-in-one machine is improved, meanwhile, when the fan works at a low frequency, the noise is small, and the influence of the noise can be redu
