AI Technical Summary

Technical Problem

Traditional water-cooling systems have limitations in temperature monitoring and parameter control, making it difficult to meet the demands of modern electronic devices for high efficiency, intelligence, and reliability.

Method used

Multiple temperature sensors are used to measure the temperature difference along the water cooling path. Combined with the flow rate, specific heat capacity and density of the coolant, the estimated power consumption of the power components is calculated. The coolant flow rate is adjusted by a preset power consumption-temperature meter, and a microcontroller is used to achieve accurate monitoring and prediction.

Benefits of technology

It enables precise monitoring and prediction of coolant flow rate, power consumption of power components and temperature, ensuring that electronic equipment operates within the optimal temperature range and improving the intelligence and reliability of the heat dissipation system.

Abstract

A water-cooled heat dissipation and monitoring system includes a pump, water-cooled piping, a water-cooling block, a water-cooling radiator, multiple temperature sensors, and a microcontroller. The pump and water-cooled piping are used to transfer the coolant. The water-cooling block is in thermal contact with a power element. The water-cooling radiator is used to facilitate heat exchange between the coolant and the surrounding environment. Multiple temperature sensors are located at at least two different points along the water-cooling path. The microcontroller is connected to the multiple temperature sensors and the pump, and is used to obtain at least one temperature difference at at least two different points and a measured flow rate of the coolant. Based on the at least one temperature difference, the measured flow rate, the specific heat capacity and density of the coolant, the microcontroller obtains an estimated power consumption and an estimated temperature of the power element, and controls the pump's rotation speed to adjust the coolant flow rate based on the estimated temperature.
