The utility model discloses a water-cooling heat dissipation structure for a
graphics card, comprising a main body, a water-cooling heat dissipation component installed on the front wall of the main body, and a fixing component installed on the rear wall of the main body. The utility model relates to the technical field of water-cooling radiators; the water-cooling heat dissipation structure for the
graphics card installs the main body above the
graphics card through the fixing component, the heat conductive sheet is located on the upper part of the graphics card, the heat conductive sheet conducts heat and dissipates heat, a circulating
water cooling tube circulates water to decompose heat, a
circulating pump draws out the
water cooling inside the circulating
water cooling tube through a second tube and a third tube, and quickly exchanges cold through a
heat exchanger through the second tube and the first tube and is injected into the fourth tube, so that when the above device dissipates heat for the graphics card, the overall heat dissipation effect of the graphics card is improved through the mutual cooperation of water cooling and
air cooling, the graphics card is kept to work stably at a normal temperature, and can be adapted to different
chassis and graphics card installation positions, and has a good effect when dissipating heat for the graphics card.
