Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically to an intelligent temperature-controlled fan. Background Technology

[0002] Intelligent temperature-controlled fans are fans that integrate temperature monitoring and intelligent control technologies. They can automatically adjust the fan speed according to changes in ambient temperature, bringing a comfortable experience while also being more energy-efficient and environmentally friendly. They have built-in high-precision temperature sensors, such as thermistors and thermocouples, that constantly sense the ambient temperature. Once there is a temperature fluctuation, the sensor quickly captures it, converts the temperature signal into an electrical signal, and transmits it to the central processing unit (CPU).

[0003] Existing intelligent temperature-controlled fans still have the following problems when in use: In terms of temperature detection, they usually have a temperature sensor in the middle, but the actual temperature detection range is limited, resulting in limited actual temperature detection accuracy. In extreme temperature environments or after long-term use, temperature detection deviations may occur, affecting the accuracy of fan speed regulation. Utility Model Content
