Description
Technical field
Present invention relates in general to a kind of heat abstractor for computer system, and more specifically, relate to a kind of heat abstractor that can reduce the gas-flow resistance of radiator fan.
Background technology
Recently, the raising of microprocessor speed has improved the processing power of computing machine significantly, but the raising of this speed has caused other electronic unit in processor and/or the computer system to produce additional heat.The high temperature that causes because of these additional heats can produce adverse influence to the many electronic units (comprising processor) in these electronic units.Therefore, just need to dissipate by the heat that these are additional.
Usually, the heat sink integrated circuit block that comprises processor or other chip that is connected to, and force blows air over heat sink with radiator fan, thus realize heat radiation.For example, traditional cooling system dispels the heat to the electronic components associated therewith that radiating requirements is arranged in order to realization by the work fan only is set.In case but there is all or part of inefficacy of fan then will cause electronic components associated therewith Yin Wendu to raise and the risk of damage of working in this traditional cooling system working method.
The problem that exists in order to solve above-mentioned traditional heat-dissipating system has also proposed another kind of cooling system, the redundant fan cooling system in the prior art.This cooling system overcomes the risk that will cause electronic components associated therewith to be damaged because of the part or all of stall of work fan in the traditional heat-dissipating system by the incremental redundancy fan.For example, Fig. 1 shows the stereographic map of the server that adopts the redundant fan cooling system; Fig. 2 shows the zoomed-in view of redundant cooling system described in Fig. 1.As depicted in figs. 1 and 2, fan group 120 is used for the heat of mainboard 110 and hardware module 130 generations is dissipated.Fan group 120 comprises three groups of tandem fan groups 122,124,126, and every group of tandem fan group 122, two fans of 124,126 li are connected in series, and redundant fan each other.When cooling system worked, all tandem fan groups 122,124,126 all were on-stream in the fan group 120, for example all turned round with 50% speed.In the tandem fan group wherein one group, a for example fan stall in the fan group 122 of series connection, then the another one fan is with the effect of full-speed operation to guarantee that whole cooling system is brought into normal play.Fig. 3 is the process flow diagram of the redundant fan cooling system work among Fig. 1.As shown in Figure 3, at step S310, cooling system detects tandem fan group 122,124,126 li one of them fan cisco unity malfunctions; Another fan that then cooling system will start in this group in S320 makes it carry out full-speed operation, and carries out step S330 simultaneously, sends alerting signal, so that user or keeper in time process this fault.
Yet, for the cooling system with many group tandem fan groups, in case fan fails in every group of tandem fan group or stall (that is, cisco unity malfunction) will go wrong.That is, the fan of stall or inefficacy will form additional resistance to another fan of with it series connection.This additional resistance can reduce the airshed by fan, causes and can not effectively dispel the heat to the electronic components associated therewith in processor and/or the computer system.This can increase the electronic unit that is dispelled the heat by cooling system and fall inferior possibility owing to failing effectively to dispel the heat.
Therefore, switch to the cooling system that redundant fan also can not affect heat dissipation even need to provide a kind of because of work fan cisco unity malfunction.
Summary of the invention

Embodiment
Describe below with reference to accompanying drawings according to an exemplary embodiment of the present invention heat abstractor in detail.
As shown in Figure 4 and Figure 5, the heat abstractor according to the embodiment of the invention comprises at least one pair of fan, elastic device 500 and coupling arrangement 600.Every pair of fan comprises work fan 300, redundant fan 400.
In Fig. 4, although work fan 300 lower end one side be connected with an end upside of redundant fan 400,, this connected mode only is exemplary.Arbitrary position of the sidepiece of work fan 300 is connected, as long as can realize work fan 300 and redundant fan 400 90-degree rotations with arbitrary position of the upside of redundant fan 300.
In addition, in Fig. 4, although elastic device 500 is connected to the lower end opposite side of work fan 300,, elastic device 500 also can be connected on arbitrary position of a described side of work fan, as long as realize making work fan 300 90-degree rotation under the effect of elastic device 500.
Certainly, can not connect between work fan 300 and the redundant fan 400 yet.At this moment, other elastic device can be set be connected with redundant fan 400, thereby when work fan 300 lost efficacy, by described other elastic device redundant fan 400 be switched to the working position from the spare space.
Fig. 6 shows the workflow diagram according to the heat abstractor of the embodiment of the invention.When vertically disposed work fan 300 breaks down and when causing work fan 300 to lose efficacy (S610), control module (not shown) control linkage device 600 disconnects (S620), so that redundant fan 400 is discharged from fixing position because disconnecting with coupling arrangement 600.Work fan 300 and redundant fan 400 (for example, around pivotal axis) 90-degree rotation under the effect of elastic device 500.As a result, the work fan 300 that breaks down becomes to lie low from initial standing state state is set, and redundant fan 400 is changed into standing state (as shown in Figure 5) from initial lying status.At this moment, stop to 300 power supplies of this work fan, and redundant fan 400 starts and start working (S630) under the control of control module.Meanwhile, system gives the alarm, and notifies keeper or user to process (S640).The airshed that the airshed that provides when in one embodiment, redundant fan 400 is worked provides when being set to equal 300 normal operation of work fan.Fig. 5 is the synoptic diagram that after the fan 300 of will working switches to redundant fan 400.
Although only show in the above-described embodiments a work fan 300 and a redundant fan 400,, can be set up in parallel many groups work fan and redundant fan.
According to the cooling system of the embodiment of the invention, have following advantage:
1, the redundant fan of initial level setting can not hinder the air-flow of the work fan discharging of normal operation, and the work fan becomes after inefficacy and is horizontally disposed with, therefore can not become and hinder the windage that becomes vertically disposed redundant fan, therefore can not affect the heat-sinking capability of cooling system;
2, redundant fan can be brand-new fan, reliability is higher, and can redundant fan be set to identical with the fan of working, so even user or management not have in time to change the work fan of inefficacy, redundant fan also can guarantee the server steady operation for a long time.
Although described the present invention with specific embodiment, it should be appreciated by those skilled in the art, in the situation that does not break away from spirit of the present invention and principle, can make various modification to the present invention.Such modification will fall within the scope of the present invention.
