VIII. New description: , [New technical field] The present invention relates to an air guiding device, and in particular to an air guiding device applied to a servo cabinet. ^ [Prior Art] In today's computer equipment, the server is widely used with its powerful functions, and different kinds of servers are developed for different needs, such as a network with better stability. The server, the storage server with mass storage function, the computing server with fast calculation function, etc., the integration of these servers is very high. For example, in the storage server, a plurality of hard disk drives are installed in one chassis. In the computing server, in general, a high-speed central processing unit is installed on one motherboard, and the server is mostly operated 24 hours a day without stopping the machine. Therefore, it is proposed to talk about the heat dissipation of the server chassis. For higher requirements, a fan holder is usually installed in the server chassis. The fan holder has multiple fan mounting areas. Each fan installation area is used to install a fan to dissipate heat from the chassis. However, the heat dissipation requirements of different components installed in the server chassis are different. Some heating components need to be guided by the air guiding device to dissipate heat. However, after the air hood is installed in the chassis, it cannot be changed according to the heating components. When the flow direction of the airflow is changed, for example, when the heating element corresponding to the air hood is removed, the air hood still guides the wind there, and the mobility is poor, and the wind is wasted. [New content] In view of the above, it is necessary to provide an air guiding device that can flexibly guide the wind according to the change of the heating element. M328765 An air guiding device comprising an air guiding hood, wherein the air guiding hood is provided with at least one rotatable air guiding sheet. The air guiding sheet is provided with a wind guiding surface for guiding airflow and a hurricane surface for blocking airflow. The air deflector can rotate between a wind guiding position that guides the airflow in a windward direction opposite to the airflow, and a windshield position in which the windshield surface opposes the airflow and blocks the airflow. Compared with the prior art, the air deflector of the air hood rotates in the air hood to selectively guide or block the wind, and the flexibility is high. [Embodiment] Referring to FIG. 1 , a preferred embodiment of the present invention includes an air guiding cover 30 and a plurality of air guiding sheets 50 disposed in the air guiding cover 30 for use in a server chassis.

The fan holder 15 is provided with a plurality of heat-dissipating components mounted on the motherboard 13. The fan 16 and the motherboard 13 are provided with a plurality of juxtaposed expansion slots 17 which are disposed on the main board 13 in the front-rear direction, and a plurality of expansion cards 18 are inserted into the expansion slots 17. Referring to FIG. 2, the air hood 30 includes an upper plate 31 and two side plates 32 extending downward from opposite ends of the upper plate 31, thereby forming an air guiding region between the upper plate 31 and the side plates 32. The length of the upper plate 31 is substantially equal to the length of the fan holder 15, such that the air hood 30 can direct the airflow generated by all of the fans 16 within the fan holder 15. The lower side of the upper plate 31 of the air guiding cover 30 is provided with a plurality of fixing plates 35 corresponding to the expansion slots 17 of the main board 13, and each side of each fixing plate 35 is respectively provided with a M328765 - a pivot 351, and the upper plate 31 is A partition plate 33 is disposed between the adjacent fixing plates 35.

The lower portion of the air guiding portion 51 is a streamlined wind guiding surface 511. The air guiding surface 511 includes a downwardly inclined inclined surface 512 and a plane 513 which is smoothly connected with the inclined surface 512. The upper portion of the air guiding portion 51 is a first block. The wind surface 514, the rotating portion 53 includes two parallel sheets 54 extending from the end of the air guiding portion -51, each of the sheets 54 corresponding to each other. The pivot 351 of the fixing plate 35 is respectively provided with a pivot hole 541, two An accommodating space 543 is provided between the sheets 54*. Referring to FIG. 1 to FIG. 4 , each fixing plate 35 of the air guiding cover 30 is firstly received in the accommodating space 543 of the air guiding plate 50 , and the two sides of the fixing plate 35 are fixed. The shaft 351 is inserted into the turning hole 541 of the sheet body 54, and the air guiding sheet 50 is pivotally mounted to the fixed plate 35. The air guiding plate 50 can guide the airflow to the air guiding position of the heating element and block the airflow. The flow position of the wind is rotated, and the adjacent air guiding piece 50 is separated by the partition 33; then the air guiding cover 30 is installed in the server chassis and located on the front side of the fan. The airflow generated by the fan 16 is guided. At this time, the air guiding sheets 50 are located on the upper side of the expansion slot 17 of the main board 11, and each expansion slot 17 corresponds to one air guiding sheet 50. An expansion card 18 is inserted into the expansion slot 17 of the motherboard 11, and some of the expansion card 18 are unplugged, and the air guiding piece 50 on the expansion slot 17 of the expansion card 18 is rotated upward to rotate to the air guide.
