Problems solved by technology

[0002] In the current scheme about the use of fans of electronic equipment, the method of controlling the speed of the cooling fan is only to adjust the speed of the fan according to the temperature of the environment in which the electronic equipment is used. However, for different altitudes, even if the ambient temperature is the same, the difference in atmospheric pressure It will still lead to different air cooling capabilities, so that the adjustment control method of fan speed applicable in low altitude areas may cause the temperature of electronic equipment components in high altitude areas to exceed the standard and cause equipment failure. Therefore, users cannot comprehensively consider electronic equipment. The air pressure changes caused by the different altitudes of the use environment cannot control the fan speed more accurately, which may easily cause damage to the components of electronic equipment
In the existing technical solution, even if the fan speed control that can fully satisfy the high-altitude area can be used, it will generate a lot of noise when used in the low-altitude area, and it is not energy-saving.
In addition, there are currently solutions to use altitude sensors to monitor different altitudes, but such altitude sensors are usually very expensive, which will increase the production cost of the product and reduce the price competitiveness of the product in the market

Abstract

The present invention provides an electronic device. The electronic device comprises a fan for heat radiation and a constant power heat source. The electronic device includes: a first temperature sensor configured to sense the ambient temperature and send the sensed ambient temperature to a calculation unit; a second temperature sensor configured to sense the temperature of the constant power heat source and send the sensed temperature of the constant power heat source to the calculation unit; and the calculation unit configured to calculate the atmospheric pressure at the position where the electronic device is located according to the ambient temperature, the sensed temperature of the constant power heat source and the rotating speed of the fan. The electronic device and the control method thereof are able to perform optimization of the fan application control method of an electronic device in the prior art to allow users to comprehensively take into account the pressure change caused by different altitude height of the application equipment where the electronic device is applied to realize the accurate control of the rotating speed of the fan so as to prevent elements of the device from damaging and realize the protection of the elements of the electronic device.
