[0207] In the embodiment, the ratio of the length dimension of the heat dissipation module 11 in the first direction to the length dimension of the air inlet grille is greater than or equal to 1.2, and the ratio of the width dimension of the heat dissipation module 11 in the third direction to the width dimension of the air inlet grille is greater than or equal to 1.5, for example, the ratio of the length dimension of the heat dissipation module 11 in the first direction to the length dimension of the air inlet grille can be 1.2, 1.3, 1.32, 1.35, 1.4, 1.5 and the like, and the ratio of the width dimension of the heat dissipation module 11 in the third direction to the width dimension of the air inlet grille can be 1.5, 1.6, 1.62, 1.7, 1.8 and the like.

[0208] In the embodiment, the ratio of the length dimension of the heat dissipation module 11 in the first direction to the length dimension of the air inlet grille is greater than or equal to 1.2, and the ratio of the width dimension of the heat dissipation module 11 in the third direction to the width dimension of the air inlet grille is greater than or equal to 1.5, so that the heat dissipation module 11 can stably and reliably cover the flow path of the fresh air flowing into the air inlet grille in the first direction and the third direction, the heat sink 10 can obtain sufficient fresh air for heat dissipation, and the heat dissipation device 100 can efficiently perform heat dissipation work.

[0209] In some embodiments of the utility model, referring to Figure 8 As shown in the figure, the fan module 22 can include a fan wheel 221, and the ratio of the maximum diameter of the fan wheel 221 to the width dimension of the air inlet grille in the third direction is greater than or equal to 0.5.

[0210] In the embodiment, the fan module 22 includes a fan wheel 221, and exemplarily, the fan module 22 can be provided with a support for fixing the fan wheel 221 and a motor and the like for driving the fan wheel 221, the ratio of the maximum diameter of the fan wheel 221 to the width dimension of the air inlet grille in the third direction is greater than or equal to 0.5, for example, the ratio of the maximum diameter of the fan wheel 221 to the width dimension of the air inlet grille in the third direction can be 0.5, 0.55, 0.6, 0.7, 0.72, 0.8 and the like.

[0211] In the embodiment, the fan module 22 includes a fan wheel 221, and the ratio of the maximum diameter of the fan wheel 221 to the width dimension of the air inlet grille in the third direction is greater than or equal to 0.54, so that the fan wheel 221 in a single fan module 22 has sufficient size to perform air flow driving work, thereby enabling the fan module 22 to meet the operation needs of the heat dissipation device 100.

[0212] It can be understood that the size of the heat dissipation device 100 as a whole in the embodiment is relatively small, and the size of the fan wheel 221 in the fan module 22 in the heat dissipation device 100 is also relatively small, and the fan wheel 221 in the embodiment adopts a small-size high-speed operation mode, and when the fixing support 21 is installed with multiple fan modules 22, the multiple small-size high-speed fan wheels 221 can be matched to realize more accurate adjustment of the air flow driving member 20.

[0213] For example, under the same heat dissipation airflow requirement, this embodiment can meet the requirements through the coordinated operation of multiple small-sized fan wheels 221. Each fan wheel 221 undertakes a portion of the total heat dissipation airflow, that is, multiple fan wheels 221 subdivide the heat dissipation airflow, and each fan wheel 221 generates a smaller airflow. At the same time, each fan wheel 221 can be started and stopped independently as needed. Thus, while meeting the heat dissipation airflow requirement, the airflow drive 20 can also further adjust the heat dissipation airflow as needed. Compared with using a single fan wheel 221, the airflow drive 20 can make more detailed adjustments to the airflow and has higher control precision. This allows the airflow drive 20 to be adjusted more flexibly according to different operating conditions, so that the operation of the airflow drive 20 can better adapt to the heat dissipation requirements of different heat dissipation conditions. To a certain extent, this can improve the operating economy of the airflow drive 20, reduce energy consumption, and reduce the noise generated by the airflow drive 20 during operation. For example, multiple fan modules 22 can be individually controlled through the Lin (Local Interconnect Network) bus.
