DETAILED DESCRIPTION OF THE INVENTION

[0023] The above objects of the invention, as well as its structural and functional features, will be described in accordance with the preferred embodiments of the accompanying drawings.

[0024] Please refer to FIGS. 4 to 6, which are perspective assembly view, perspective exploded view and cross-sectional view of one preferred embodiment of a diversion structure for heat dissipation of display card of the invention respectively. It can be clearly seen from the figures that a diversion structure for heat dissipation of display card 2 includes a display card module 3, a heat dissipation module 4, and a backplate module 5.

[0025] Wherein the display card module 3 is provided with a plurality of electronic component areas 31 and a plurality of wiring areas 32 thereon, wherein the electronic component areas 31 are provided for disposition of electronic components, and the wiring areas 32 are provided for disposition of power conducting wires. A plurality of empty plate areas 33 are further formed on the display card module 3, wherein the empty plate areas 33 can be formed between the adjacent electronic component areas 31, between the adjacent wiring areas 32, and between the adjacent electronic component areas 31 and the wiring areas 32, the empty plate areas 33 are formed with a plurality of guide holes 331 thereon, and the guide holes 331 penetrate the display card module 3.

[0026] Wherein the heat dissipation module 4 is disposed at a position on an upper side of the display card module 3, and the heat dissipation module 4 has at least one fan 41, at least one heat dissipation fin set 42 and at least one bottom plate 43. The heat dissipation module 4 is attached on the display card module 3 via the bottom plate 43, the heat dissipation fin set 42 is provided with a thermal conductive pipe 421, and the heat dissipation fin set 42 communicates with the guide holes 331.

[0027] Wherein the backplate module 5 is disposed on a lower side of the display card module 3, a plurality of through holes 51 are formed on the backplate module 5, and the through holes 51 communicate with the guide holes 331, or the through holes 51 are disposed adjacent to the guide holes 331.

[0028] Please continue to refer to the aforementioned figures and FIGS. 7 and 8, which are cross-sectional view and perspective view of implementation of the diversion structure for heat dissipation of display card of the invention respectively. It can be clearly seen from the figures that the fan 41 generates an airflow and when the airflow is sent toward the heat dissipation fin set 42, the airflow generated by the fan 41 takes away the heat energy of the heat dissipation fin set 42, the airflow is then sent toward the display card module 3. When the airflow is sent toward the display card module 3, the airflow passes through the guide holes 331 and is sent toward another side of the display card module 3 opposite to a side facing the heat dissipation module 4, and then passes through the through holes 51, so that the airflow is away from the display card module 3 and the heat dissipation module 4, and the airflow is not blocked by the display card module 3, so as to prevent hot air from flowing back and being sucked in by the fan 41 again, avoid the occurrence of residual heat in the display card module 3, also avoid generating of mutual interfering wind pressure on the display card module 3 and provide a pressure relief effect, and therefore achieving the efficacies of increasing an overall air output and improving a heat dissipation efficiency.

[0029] It is to be understood that the above description of the preferred embodiments of the present invention is not used to limit the present invention, and changes in accordance with the concepts of the present invention may be made without departing from the spirit of the present invention, for example, the equivalent effects produced by various transformations, variations, modifications and applications made to the configurations or arrangements shall still fall within the scope covered by the appended claims of the present invention.
