Problems solved by technology
However, because the narrow space on both sides of the graphics card or video image card limits the size of the radiator installed on it, especially the height of the radiator, the fan is generally placed on one side of the radiator in parallel to the circuit board.
However, the flat fan occupies the small space of the radiator and greatly limits the effective heat dissipation area of the radiator. At the same time, it cannot provide enough wind pressure for the radiator base with concentrated heat.
Therefore, the size of the flat fan is greatly limited, and it is impossible to use a large fan to provide sufficient air flow and air pressure for the radiator

A video card radiating device comprises a base, a radiation fin unit arranged on the base and a fan fixed at one side of the radiation fin unit. One end of the radiation fin unit forms an included plane and the fan is stick to the inclined plane. The fan of the video card radiating device is obliquely arranged at one side of the radiation fin unit. The inclination angle of the fan is selected according to the practical maximum height allowed by the space that the radiator is located at to realize the maximization of the radiating area of the radiating fins and the fan size. Moreover, the fan arranged at one side of the radiation fin unit generates a strong air flow that directly blows to a radiation fin unit high temperature area corresponding to the upward side of the middle part of the base contacted with a heat source to mainly distribute the compulsive air flow generated by the fans and the air pressure thereof on the high temperature area of the video card radiating device; thereby effectively improving the radiating efficiency.
Description
technical field [0001] The invention relates to a heat dissipation device, in particular to a graphics card heat dissipation device for cooling electronic components on a graphics card. Background technique [0002] With the continuous development of the computer industry, the operating frequency and speed of electronic components, especially the processors installed on graphics cards and video graphics cards, continue to increase, and the heat generated is increasing. If it is not eliminated in time, the accumulation of heat generated during its operation will cause An increase in temperature will affect the normal operation of heating electronic components. [0003] Generally, the industry usually installs a heat sink on the processor to dissipate heat. In order to further meet the increasing heat dissipation needs of some electronic components, a fan can also be installed on one side of the radiator to accelerate the surrounding air flow, so as to take away the heat of t...
