<P>PROBLEM TO BE SOLVED: To effectively prevent an air flow from being interrupted in a process of introducing/delivering the air flow into/out of a fan wheel in a horizontal direction. <P>SOLUTION: This horizontal convection type fan includes a fan frame 1, a driving module 2 and the fan wheel 3. The fan frame 1 includes a first sealing part 11 and a second sealing part 12. A side wall part 13 is provided between the first sealing part 11 and the second sealing part 12, and a wind inlet 131 and a wind output 132 are provided in the side wall part 13. The driving module 2 is provided inside the fan frame 1, and the driving module 2 is joined to the first sealing part 11. One hub 31 and a plurality of blades 32 are provided in the fan wheel 3, and the hub 31 is turnably joined to the driving module 2 and the blades 32 are connected to the hub 31. A level difference exists between an upper edge 321 of each blade 32 formed to be directed to the second sealing part 12 and the hub 31. <P>COPYRIGHT: (C)2013,JPO&INPIT |
