Description
Technical field
The present invention relates to a kind of fan and linkage structure thereof, particularly relate to a kind of serial fan and linkage structure thereof.
Background technique
Along with electronic product towards high-performance, high frequency, high-speed and lightening developing rapidly, cause the heating temperature of electronic product more and more higher, thereby be easy to generate wild effect, influence production reliability, so heat radiation has become one of important topic of present electronic product exploitation.
In heat-generating system now, utilizing fan is to be common structure setting as sink, but for the electronic product that produces a large amount of heat energy, single fan is not sufficient to effective dissipation heat energy, in addition, cause the interruption of sink running for avoiding single fan to hinder for some reason, so generally be to utilize to use a plurality of fans simultaneously, in order to reach the purpose of the air quantity that improves air-flow.Wherein, this each fan is an axial flow fan.
Please refer to shown in Figure 1ly, it is the schematic representation of existing a kind of fan group 1.Existing fan group 1 is to be connected mutually by two identical fans (for example being first fan 10 and second fan 11) to assemble, and the movable vane 101,111 by fan 10,11 rotates and produces an air-flow and enter and flow to 11 air-out of second fan by first fan 10.Yet, because general first fan 10 and second fan 11 all are provided with a plurality of stator blades 102,112 at exhaust outlet, so when the air-flow air-out, be vertical with the plane of exhaust outlet and be deflection a little making that the flow direction of air-flow is non-, so when first fan 10 and 11 assemblings of second fan, in the time of will flowing into second fan 11 by the air-flow of first fan, 10 air-out, flow direction generation deflection because of its air-flow, so air-flow part component can be offseted, and can cause the wind speed and the air quantity of 11 air-out of second fan to reduce.Thus, when first fan 10 and the assembling of second fan 11, the air-out usefulness that causes first fan 10 and second fan 11 on the contrary influences each other and interfering with each other, so in case dispose and design when not good, another fan of connecting does not only add the effect of taking advantage of, and may cause counter productive to produce on the contrary.
In view of this, how to provide a kind of blast and air quantity of effective increase air-out, and can improve the serial fan and the linkage structure thereof of integral heat sink usefulness, real is one of important topic now.
Summary of the invention
Because above-mentioned problem, the object of the present invention is to provide a kind of serial fan and linkage structure thereof that increases the blast and the air quantity of air-out, and and then effectively improve its heat dissipation.
For reaching above-mentioned purpose, according to a kind of linkage structure of the present invention, be applied to a serial fan, serial fan comprises a upstream fan and the fan of urticaria once, and the size of upstream fan and the size of downstream fan are inequality, wherein, linkage structure connects upstream fan and downstream fan, makes the upstream fan setting of connecting with downstream fan.
For reaching above-mentioned purpose, foundation a kind of serial fan of the present invention comprises a upstream fan, once urticaria is fanned and a linkage structure.Wherein, linkage structure connects upstream fan and downstream fan, makes the upstream fan setting of connecting with downstream fan, and the size of upstream fan and the size of downstream fan are inequality.
For reaching above-mentioned purpose, foundation a kind of serial fan of the present invention comprises a upstream fan, a middle reaches fan, one first linkage structure, once urticaria is fanned and one second linkage structure.Wherein, first linkage structure connects upstream fan and middle reaches fan, makes the upstream fan setting of connecting with the middle reaches fan, and the size of the size of upstream fan and middle reaches fan is inequality; Second linkage structure connects middle reaches fan and downstream fan, makes the setting of connecting with downstream fan of middle reaches fan, and the size of middle reaches fan and the size of downstream fan are inequality.
From the above, because of according to a kind of serial fan of the present invention and linkage structure thereof being forms with a plurality of fan series connection assemblings of at least one linkage structure with different size, wherein when linkage structure connects the downstream fan of the upstream fan of a large-size and a reduced size, air-flow is to be entered by upstream fan, be directed to downstream fan and air-out via linkage structure, because air-flow is concentrated air-out, therefore effectively improved the air-out blast of serial fan.In addition, when two linkage structures connect a upstream fan, a middle reaches fan reaches urticaria fan, and the size of middle reaches fan is than the size of upstream fan and downstream fan hour, enter and the air-flow of the downstream fan air-out that arrives by upstream fan via the middle reaches fan, because through the pressurization of middle reaches fan, and the air-out via the downstream fan driving of large-size at last, therefore except the air-out blast is raised, air quantity also increases simultaneously, with the lifting of the integral heat sink usefulness that reaches serial fan.
