The drawings included herein provide a further understanding of the invention. A brief introduction of the drawings is as follows:
Reference is made to
The housing 10 can be a housing for power supplies, a housing for backup power supplies, a housing for computers, a housing for industrial computers, a housing for a server, a housing for UPSs, a housing for external RAID boxes, a housing for external hard disk boxes, a housing for an external optical drive, a housing for a keyboard, a housing for laptop heat-exhausting boards, a housing for overhead projectors, a housing for medical detecting equipment, or a housing for other devices having a fan. In this embodiment, the housing for a computer is taken as an example. The housing 10 includes a side board 11 that is made of iron. On the outside of the side board 11, there is a square opening 111. The opening 111 is interlinked with the inner part of the housing 10.
The fastening frame 20 is a board-shaped body and has two blocking walls 21. The two blocking walls 21 are opposite to each other and there is a distance between the two blocking walls 21. A fan receiving area 22 is formed between the two blocking walls 21 and is used for receiving the fan body 30. The fan receiving area 22 is interlinked with the opening 111.
An assembling part 23 is connected with the rear side of the blocking wall 21. The assembling part 23 is located in the fan receiving area 22. On the upper and lower ends of the assembling part 23, there is a screw hole 231 for assembling the fan body 30.
A fixing part 24 is connected with the front side of the blocking wall 21. The fixing part 24 leans on the inner side of the side board 11 and is adjacent to the left and right sides of the opening 111. The two fixing parts 23 is connected to the inner surface of the side board 11 via a welding method, a riveting method, or a locking method so that the fastening frame 20 is fastened to the housing 10.
The fan body 30 can be an axial flow fan, a centrifugal fan, or a rolling-typed fan (also known as a traverse flow fan). In this embodiment, the fan body 30 is an axial flow fan. On the four corners of the fan body 30, there is a through hole 31 for fastening the fan body 30 to the housing 10.
When the fan body 30 is installed, the fan body 30 passes through the opening 111 and is received in the fan receiving area 11 of the fastening frame 20. Next, four screws 40 pass through four through holes 31 of the fan body 30 to screw the fan body 30 in the screw hole 231 of the assembling part 23. Thereby, the fan body 30 is locked on the fastening frame 20 and the fan body 30 is installed at the housing 10 via the opening 111.
When the fan body 30 is disassembled, the four screws 40 screwed at the four corners of the fan body 30 are released via the opening 111 so as to unlock the fan body 30. Therefore, the fan body 30 can be moved outward from the fastening frame 20. Then, the fan body 30 is disassembled from the housing 10 via the opening 111.
Reference is made to
On the four corners of the fan body 30, there are two magnets 32 that have a round shape. The two magnets 32 are symmetrically disposed along the diagonal line of the fan body 30.
When the fan body 30 is installed, the fan body 30 passes through the opening 111 and is attached on the assembling part 23 of the fastening frame 20 via the magnetic force of the magnets 32, and is received in the fan receiving area 11. Thereby, the fan body 30 is installed at the housing 10 via the opening 111.
When the fan body 30 is disassembled, the magnetic force between the fan body 30 and the fastening frame 20 is merely released so that the fan body 30 can be moved from the fastening frame 20. Therefore, the fan body 30 is disassembled via the opening 111.

Reference is made to
The fastening frame 20 is a frame that has an opening-shaped on the front side. The space surrounded by the four sides of the fastening frame 20 forms a fan receiving area 22. The fan receiving area 22 is interlinked with the opening 11′. The fastening frame 20 has a flexible flake 26 located at the lower side of the fan receiving area 22. The center of the flexible flake 26 has an arc-shape that is protruding, and is flexible. The two ends of the flexible flake 26 are connected with the bottom of the fastening frame 20. The fastening frame 20 has two blocking walls 21 located above the flexible flake 26. The two blocking walls 21 are disposed at the left and right sides and there is a distance between the two blocking walls 21. On the upper side of the two blocking walls 21, there is a blocking block 27 that corresponds to the flexible flake 26. The blocking block 27 has a triangular shape and the slope side of the triangle faces downward.
When the fan body 30 is installed, the fan body 30 inclinedly passes through the opening 11′ and is received in the fan receiving area 22. Next, the left and right sides of the fan body 30 lean on the inner surface of the two blocking walls 21 and the flexible flake 26 is pressed to deform so that the fan body 30 moves inward, and leans and pushes below the two blocking blocks 27. The flexible flake 26 recovers and is wedged below the fan body 30. Thereby, the fan body 30 is wedged in the fastening frame 20 and the fan body 30 is installed at the housing 10′ via the opening 11′.
When the fan body 30 is disassembled, the fan body 30 is pressed downward to make the flexible flake 26 deform so that the fan body 30 escapes from the leaning and pushing area of the two blocking blocks 27. Therefore, the fan body 30 is inclinedly moved out from the fastening frame 20 via the opening 11′. Then, the fan body 30 is disassembled from the housing 10′.
Reference is made to
When the fan body 30 is installed, the fan body 30 passes through the opening 11′ and is received in the fan receiving area 22 of the fastening frame 20. Next, the four wedges 28 wedge the four sides of the fan body 30 to wedge the fan body 30 on the and the fan body 30 is installed at the housing 10′.
When the fan body 30 is disassembled, the user pushes the four wedges 28 so as to release the fan body 30. Therefore, the fan body 30 is moved out from the fastening frame 20 via the opening 11′, and the fan body 30 is disassembled from the housing 10′.
The structure for assembling and disassembling a fan of the present invention allows the fan to be directly removed from the opening of the housing of the device to maintain or replace the fan. The user does not need to disassemble the housing of the device or the inner components. It is convenient. When problems occur with the fan, the user can easily and rapidly assemble or disassemble the fan so that the problem can be fixed. The problem of lowering the heat-exhausting efficiency due to the dust accumulation is overcome. Therefore, the inner components can operate below their operating temperature. The components are not damaged due to the overheating. The usage life of the device is extended.
The description above only illustrates specific embodiments and examples of the invention. The invention should therefore cover various modifications and variations made to the herein-described structure and operations of the invention, provided they fall within the scope of the invention as defined in the following appended claims.
