Portable computer water cooling system based on temperature controller
Abstract
With the popularity of high-performance computers and the increase in operating loads, the problem of device overheating is becoming increasingly prominent. Long term high temperature operation not only leads to a decrease in computer performance and lagging, but may also shorten the lifespan of hardware, and even cause serious problems such as crashes and hardware damage. Therefore, it is necessary to develop a computer cooling device that can accurately control temperature, is convenient and efficient.
This design proposes a portable computer water cooling system based on STM32F103C8T6 microcontroller. The main functions of the system include: real-time monitoring of the environment and computer temperature through the DS18B20 temperature detection module; When the temperature exceeds the set maximum value, automatically start two water pumps for cold water circulation and heat dissipation; Users can set the maximum temperature value through buttons and manually turn on or off the water cooling function; Real time display of current temperature and water cooling status through OLED display screen; The integrated WiFi module uploads temperature data to the mobile phone, supporting remote temperature viewing, setting maximum temperature values, and controlling water cooling switches.
The function of this system is to provide an intelligent and portable cooling solution for computers. Through real-time temperature monitoring and automatic start stop control, precise heat dissipation is achieved to avoid excessive or insufficient cooling; The dual interaction between buttons and mobile phones enhances operational flexibility and meets the needs of different scenarios; OLED display makes temperature and device status clear at a glance, making it easy for users to intuitively grasp the heat dissipation situation. The overall design effectively solves the problem of high temperature operation of computers, ensuring stable equipment performance and extending service life.
