Description

Technical Field

[0001] The present invention relates to the field of graphics card radiators, and in particular to a water-cooled radiator and method for a computer graphics card. Background Art

[0002] With the development of electronic technology, the performance of electronic equipment has improved rapidly, and the power dissipation of the entire system has also increased dramatically. The increase in power dissipation and the requirement for miniaturization have caused the problem of heat dissipation to become increasingly prominent. If this problem cannot be solved well, it will not only affect the performance of the equipment, but also shorten the life of the equipment. Studies have shown that among the various factors that affect the reliability of electronic devices, heat dissipation is crucial. The heat generated by high-power semiconductor devices will cause the temperature of the chip to rise. If there is no appropriate heat dissipation measure, the temperature of the chip may exceed the maximum allowable temperature, resulting in deterioration of device performance and even damage.

[0003] The full name of the graphics card (Video card, Graphics card) is the display interface card, also known as the display adapter, which is one of the most basic configuration and most important accessories of the computer. As an important component of the computer host, the graphics card is a device for the computer to convert digital and analog signals, and is responsible for the task of outputting display graphics. The graphics card is connected to the computer motherboard. It converts the computer's digital signal into an analog signal for the monitor to display. At the same time, the graphics card also has image processing capabilities, which can assist the CPU to work and improve the overall operating speed. Graphics cards often generate a lot of heat when working, and the temperature even exceeds 100°C. Traditional air-cooled heat dissipation devices have poor heat dissipation effects and cannot cool down the graphics card in time, which seriously affects the normal operation of the graphics card, which in turn greatly reduces the performance of the graphics card and affects the user experience.

[0004] Therefore, it is necessary to invent a water-cooled radiator and method for computer graphics cards to solve the above problems. Summary of the invention
