However, this cooling system still has the following disadvantages: first, even in the second position, the blades themselves still produce resistance to the fan
Second, its structure is more complex

Embodiment Construction

[0024] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings. But the invention can be embodied in many different ways as defined and covered by the claims. The same components are denoted by the same reference numerals in the drawings.

[0025] refer to figure 1 , figure 1 It shows the arrangement of multiple fans 1 in the redundant cooling system of the present invention, the multiple fans 1 are accommodated in the casing 10, and the multiple fans 1 are connected in series. Each fan 1 includes a hub 3 and a plurality of fan blades 2 connected to the hub 3 .

[0026] refer to figure 2 , image 3 . figure 2 , image 3 A perspective view and a plan view of the fan blade 2 of the fan 1 in a redundant cooling system in a first position relative to the hub 3 are respectively shown. A slot 4 is provided on the hub 3, and the fan blade 2 is movably arranged in the slot 4. A pivot 7 is arranged in the groove 4, ...

Abstract

The invention discloses a redundant cooling system and a running method thereof. The cooling system comprises a plurality of fans which are arranged in series; each fan moves between at least a first position and a second position relatively to a hub; the resistance force of the fan vane at the first position on the fluid flow which flows through the cooling system is less than that at the second position on the fluid flow which flows through the cooling system; the redundant cooling system is characterized in that when the rotation speed is lower than the prearranged rotation speed, all the fan vanes are kept at the first position; when the rotation speed is higher than the prearranged rotation speed, all the fan vanes moves from the first position to the second position by using centrifugal force generated when the fan vane rotates. The invention also relates to the corresponding running method of the cooling system. The redundant cooling system and the running method of the invention have the advantages that the fluid resistance force can be reduced to be extremely low and the running method can be realized by an extremely single type.

Description

technical field [0001] The invention relates to a method for operating a redundant cooling system. More specifically, the present invention relates to a redundant cooling system and an operating method thereof for improving the reliability of the redundant cooling system. Background technique [0002] With the development of computer technology, the processing speed of microprocessor is getting higher and higher. Increases in the speed of microprocessors have significantly increased the processing capabilities of computers, but at the same time, such increases in speed have resulted in higher levels of additional heat generated by the processor and / or other components in the computer system. High temperatures adversely affect many components, including the processor, and this heat needs to be dissipated. [0003] Typically a cooling fan is used to force air across the heat sink. One solution to improve the cooling capacity is to arrange multiple cooling fans in series, th...
