Abstract

A heat-dissipating assembly includes a plurality of heat-dissipating devices, each of which includes a frame having at least one locating window for allowing the heat-dissipating device to inhale air and discharge airflow, and a stream-guiding wall formed beside the locating window; and at least one blade structure mounted in the locating window of the frame. In addition, each heat-dissipating device further includes at least one engaging medium to be engaged with a corresponding engaging medium of another heat-dissipating device, thereby allowing the plurality of heat-dissipating devices to be combined in parallel, side by side, or in tiers.

Claims

1. A heat-dissipating device comprising:

a frame having at least one locating window for allowing said heat-dissipating device to inhale air and discharge airflow, and a stream-guiding wall formed beside said at least one locating window; and

at least one blade structure mounted in said at least one locating window of said frame.

2. The heat-dissipating device according to claim 1 wherein said locating window has an inlet and an outlet, respectively disposed in the first plane and the second plane.

3. The heat-dissipating device according to claim 2 wherein said first plane and said second plane are perpendicular to each other.

4. The heat-dissipating device according to claim 3 wherein said heat-dissipating device is a centrifugal fan.

5. The heat-dissipating device according to claim 2 wherein said inlet and said outlet are disposed in two planes which are parallel with each other.

6. The heat-dissipating device according to claim 5 wherein said heat-dissipating device is an axial-flow fan.

7. The heat-dissipating device according to claim 2 wherein said stream-guiding wall is disposed beside said inlet of said locating window.

8. The heat-dissipating device according to claim 1 wherein said heat-dissipating device is one selected from a group consisting of a centrifugal fan, an axial-flow fan and a cross fan.

9. The heat-dissipating device according to claim 1 wherein said frame further includes a first engaging medium to be engaged with a first corresponding engaging medium of a frame of another heat-dissipating device.

10. The heat-dissipating device according to claim 9 wherein said first engaging medium is a protruding piece and said first corresponding engaging medium is a concavity.

11. The heat-dissipating device according to claim 9, wherein said frame further includes a second engaging medium to be engaged with a second corresponding engaging medium of another heat-dissipating frame of another heat-dissipating device.

12. A heat-dissipating assembly comprising:

a plurality of heat-dissipating devices, each of which includes;

a frame having a locating window for allowing said heat-dissipating device to inhale air and discharge airflow, and a stream-guiding wall formed beside said locating window; and

a blade structure mounted in said locating window of said frame.

13. The heat-dissipating assembly according to claim 12 wherein said locating window has an inlet and an outlet, respectively disposed in the first plane and the second plane.

14. The heat-dissipating assembly according to claim 13 wherein said first plane and said second plane are perpendicular to each other.

15. The heat-dissipating assembly according to claim 14 wherein said heat-dissipating device is a centrifugal fan.

16. The heat-dissipating assembly according to claim 13 wherein said inlet and said outlet are disposed in two planes which are parallel with each other.

17. The heat-dissipating assembly according to claim 16 wherein said heat-dissipating device is an axial-flow fan.

18. The heat-dissipating assembly according to claim 12 wherein said heat-dissipating device further includes at least one engaging medium to be engaged with a corresponding engaging medium of a frame of another heat-dissipating device.

19. The heat-dissipating assembly according to claim 18 wherein said engaging medium is a protruding piece and said corresponding engaging medium is a concavity.

20. A heat-dissipating device comprising:

a single frame having a plurality of locating windows for allowing said heat-dissipating device to inhale air and discharge airflow; and

a plurality of blade structures respectively mounted in said locating windows.

21. The heat-dissipating device according to claim 20 wherein said frame further includes at least one engaging medium to be engaged with a corresponding engaging medium of a frame of another heat-dissipating device.

22. The heat-dissipating device according to claim 20 wherein said frame further includes a stream-guiding wall formed beside said plurality of locating windows.

23. A heat-dissipating assembly comprising:

a plurality of heat-dissipating devices, each of which includes;

a frame having a locating window for allowing said heat-dissipating device to take in and exhaust airflow, and a stream-guiding wall formed beside said locating window;

a blade structure mounted in said locating window of said frame; and

an engaging medium for engagement with a corresponding engaging medium of a frame of another heat-dissipating device.
