V. New description: [New technical field] [0001] This is related to the fan holder, especially for a combined fan holder installed in the server case. [Prior Art] [0002] Traditionally An industrial computer (such as a disk array system or a server system) is provided with an electronic device such as a motherboard and a power supply inside the chassis, and the inside of the chassis houses a plurality of hard disks arranged in an array to provide a user. A large amount of data storage space. [0003] The above system generates high temperature during operation, and in order to ensure stable operation of the system, adding a plurality of cooling fans in the chassis is a common heat dissipation solution. The embodiment is characterized in that a fan holder is arranged inside the chassis, and the cooling fans are fixed on the fan holder. The forced air flow is generated by the fan to move the high tropical inside the chassis. [0004] The conventional fan holder is a metal frame. For different numbers of heat dissipation winds, different molds are required to make side frames of different sizes or directions. Finally, the side edges are welded. The frame is combined; however, this method not only has high cost of materials and molds, but also is time consuming and labor intensive in assembly, so it does not meet the requirements. [0005] In addition, the known metal fan holder is usually locked by a screw. 'When the field fan is running, the screw and the metal piece are extremely easy to be generated by vibration, and even the bolt is loosened, thereby causing Safety concerns in use. [0006] There is I·!·. k μ This creator has improved and solved the above-mentioned deficiencies, but it has been specially developed, researched and used in conjunction with the theory. Finally, it is proposed that the design is reasonable and there is a 3 page/total 21 page form. No. A0101 M418521 ίοσYear on September 14th, the child is replacing the page to improve the above-mentioned creation. [New Content] [0007] One of the aims of this creation is to provide a combined fan holder to simplify the assembly method and reduce material and mold costs.
