Abstract

A fan assembly includes a first fan device having an engaging medium, and a second fan device having a corresponding engaging medium for engaging with the engaging medium of the first fan device, thereby allowing the second fan device to be combined with the first fan device. The fan device includes a fan frame having the engaging medium adapted to engage with the corresponding engaging medium of another fan frame of another fan device, and a fan secured in the fan frame.

Claims

1. A fan assembly, comprising

a first fan device having an engaging medium;

and

a second fan device having a corresponding engaging medium for engaging with said engaging medium of said first fan device, thereby allowing said second fan device to be combined with said first fan device, wherein said engaging medium of said first fan device is a protruding piece, and said corresponding engaging medium of said second fan device is a receptacle.

2. The fan assembly according to claim 1, wherein said first fan device further comprises an additional engaging medium for engaging with a corresponding engaging medium of a third fan device, thereby allowing said third fan device to be combined with said first fan device.

3. The fan assembly according to claim 2, wherein said second fan device further comprises an additional engaging medium for engaging with a corresponding engaging medium of a fourth fan device, thereby allowing said fourth fan device to be combined with said second fan device.

4. The fan assembly according to claim 1, wherein each of said first fan device, said second fan device, said third fan device and said fourth fan device is one selected from a group consisting of a centrifugal fan, an axial-flow fan and a cross fan.

5. The fan assembly according to claim 1, further comprising plural fan devices to be combined with said first fan device and second fan device in parallel.

6. The fan assembly according to claim 1, further comprising plural fan devices to be combined with said first fan device and second fan device vertically in parallel.

7. A first fan device, comprising:

a fan frame having a first engaging medium adapted to engage with a corresponding engaging medium of a second fan device; and

a fan secured in said fan frame, wherein said first engaging medium is a protruding piece, and said corresponding engaging medium is a receptacle.

8. The fan device according to claim 7, wherein said fan device is one selected from a group consisting of a centrifugal fan, an axial-flow fan and a cross fan.

9. The first fan device according to claim 7, wherein said fan frame further comprises a second engaging medium adapted to engage with a corresponding engaging medium of a third fan device.

10. A fan assembly, comprising:

plural fan devices, each of which comprises;

a fan frame having a first engaging medium adapted to engage with a corresponding engaging medium of a first adjacent fan device of the plural fan devices; and

a fan secured in said fan frame;

wherein said first engaging medium is a protruding piece, and said corresponding engaging medium is a receptacle.

11. The fan assembly according to claim 10, wherein each of the plural fan devices further comprises a second engaging medium adapted to engage with a corresponding engaging medium of a second adjacent fan device of the plural fan devices.

12. The fan assembly according to claim 10, wherein each of said plural fan devices is one selected from a group consisting of a centrifugal fan, an axial-flow fan and a cross fan.
