Description

Technical Field

[0001] The utility model relates to the technical field of water-cooling radiators, in particular to a water-cooling heat dissipation structure for a graphics card. Background Art

[0002] The water-cooled radiator has a water inlet and a water outlet, and there are multiple water channels inside the radiator, which can give full play to the advantages of water cooling and take away more heat. This is the basic principle of the water-cooled radiator. From the perspective of water cooling installation, it can be divided into two types: internal water cooling and external water cooling. For internal water cooling, it is mainly composed of a radiator, water pipes, a water pump, and sufficient water sources. This means that most water-cooled heat dissipation systems are large in "volume" and require sufficient space inside the chassis. For external water-cooled radiators, since the heat dissipation water tank and water pump and other working components are all arranged outside the chassis, it not only reduces the space occupied in the chassis, but also can achieve better heat dissipation effects.

[0004] The above device has certain shortcomings when in use: when the above device is working, the heat can be accurately dissipated by sliding to adjust the position of the heat sink and the water cooling plate, but since the entire device is installed inside the chassis, when the heat dissipation position needs to be adjusted, the chassis baffle needs to be removed, which is more troublesome during operation.
