New Description: [New Technology Target Area] This creation relates to a fan holder, especially a fan holder used in a server-chassis. - [Previous brain] 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, it is usually installed in one chassis of the server. Multiple hard disk drives, in the computing server, a plurality of high-speed central processing units are installed on the main board, and the servers are mostly operated 24 hours a day, so the heat dissipation of the server chassis is proposed. In the higher requirements, a fan holder is usually installed in the server chassis. There are multiple fan installation areas on the fan holder. A fan is installed in each fan installation area I to dissipate heat from the chassis. - However, due to the different components installed in different server systems, the heat dissipation requirements of these server chassis are different. Some server chassis require more heat dissipation than the south 5 in each fan installation area of the fan holder. There are fans installed inside, and some servers have lower heat dissipation requirements. Only fans need to be installed in the fan installation area of the fan holder, but each fan installation area is connected to the inside and outside of the server chassis. When the fan cools the server chassis, the airflow will also flow through the fan installation area where the fan is not installed, which may cause turbulence, affect the orderly flow of the airflow inside the chassis, and reduce the heat dissipation of the chassis. [New content] In view of the above, it is necessary to provide a fan holder that avoids turbulence. A fan fixing frame is configured to install a fan in a chassis, wherein the fan fixing frame is provided with a plurality of fan mounting areas, and the fan fixing frame defines a venting port connecting the inner side and the outer side of the chassis at each fan's mounting area. There is no fan installed in the middle fan installation area, and a windshield is installed at the vent of the fan installation area of the unmounted fan to close the vent. Compared with the prior art, the windshield of the fan holder closes the vent in the fan installation area where the fan is not installed, and the airflow is not circulated by the fan installation area where the fan is not installed, thereby ensuring the airflow inside the chassis. Orderly flow. [Embodiment] Referring to Figure 1, a fan holder 20 is used to mount a fan into a server chassis 10. ~ The chassis 10 includes a bottom plate 11 and two side plates 13 extending perpendicularly from opposite sides of the bottom plate 11. The fan holder 20 includes a first mounting plate 21 and a second mounting plate 23 parallel to each other. The bottom edges of the first mounting plate 21 and the second mounting plate 23 are respectively provided with a folded flange 26, and the first mounting plate There are five vents 211 on the 21, the vents 211 are arranged in a straight line in the horizontal direction, and the inner edge of the upper end of each vent 211 is provided with a horizontal upper edge 214, and the inner edge of the lower end is provided with a horizontal lower edge. 212. The first mounting plate 21 defines a vertical positioning slot 215 on each side of each of the vents 211 of the 7 M326770. Each positioning slot 215 extends through the upper end of the first mounting board 21. The venting opening 211 of the second mounting plate 23 corresponding to the first mounting plate 21 is also provided with five venting ports 231 so as to form five fan mounting regions 27 between the first mounting plate 21 and the second mounting plate 23. One of the five fan mounting areas 27 of the fan holder 20 is mounted with one fan 12, and the other wind's fan mounting area 27 is not provided with the fan 12. The flanges 26 of the fan holder 20 are placed on the bottom plate 11 of the chassis 10, and the two sides of the first mounting plate 21 and the second mounting plate 23 are fixed to the side plates 13 of the chassis 10, thereby fixing the fan holder 20. Fixed to the chassis 10. Referring to FIG. 1 and FIG. 2, a windshield 40 includes a square body 41. A middle portion of the upper end of the body 41 is provided with a notch 43. The lower edge of the notch 43 extends rearward to form a bent buckle piece 44. The support portion 441 includes a support portion 441 and an elastic portion 443. The support portion 441 is formed by extending from the lower edge of the notch 43 to the body 41. The elastic portion 443 is bent forward and upward by one end of the support portion 441. And extending from the rear side of the windshield 40 to the front side of the windshield 40, the free end of the elastic portion 443 slightly passes over the plane of the body 41, and forms a vertical snap portion 445; the lower end of the body 41 is forwardly forward Then, a flap 42 is formed to extend downwardly. The flap 42 includes an abutting portion 421 perpendicular to the body 41 and an engaging portion 423 parallel to the body 41. The engaging portion 423 protrudes from the plane of the body 41. The width of the abutting portion 421 is slightly larger than the thickness of the first mounting plate 21. A positioning piece 45 is disposed on each of the left and right sides of the body 41. Referring to FIG. 1 and FIG. 3, when one of the fan mounts 8 M326770 mounting area 27 of the fan holder 20 is not equipped with the fan 12, the windshield 40 can be used to close the corresponding vent 211, and the windshield 40 is lowered. The front side of the body 41 is attached to the inner side of the first mounting plate 21, and the left and right sides of the windshield 40 are slid into the corresponding positioning slots 215 of the first mounting plate 21 to block the wind. The abutting portion 421 of the flap 42 at the lower end of the 40 abuts against the lower edge 212 of the vent 211, and the engaging portion 423 is snapped to the outer side of the first mounting plate 21, and then the upper end of the windshield 40 is moved forward. The latching portion 445 of the latching piece 44 abuts against the upper edge 214 of the venting opening 211 to elastically deform the elastic portion 443 of the latching piece 44, and the latching portion 445 is slidable through the venting opening from the inner side of the first mounting plate 21 The upper edge 214 of the 211 is fastened to the outer side of the first mounting plate 21, so that the windshield 40 is fixed to the vent 211 of the first mounting plate 21, and the vent 211 is closed, and the rear cover is not shown. Fixed to the upper end of the chassis 10 to close the chassis 10, when the fan 12 heats the chassis 10, the airflow will not By circulating the fan mounting area 27 where the fan 12 is not installed, an orderly flow of airflow inside the chassis is ensured. When the fan 12 is installed in the fan mounting area of the fan holder 20 in which the fan 12 is not installed, the elastic portion 443 of the tab 44 of the windshield 40 is pressed downward, and then the windshield 40 is slightly moved backward. At the upper end, the locking portion 445 of the locking piece 44 is slid from the outer side of the first mounting plate 21 through the upper edge 214 of the vent 211 to the inner side of the first mounting plate 21, so as to be upward from the fan holder 20. The windshield 40 is withdrawn, and a fan can be installed in the fan mounting area 27 at this time.
