Abstract
The utility model discloses a heat dissipating device including an air inlet channel, an air outlet channel and at least three accommodation cavities communicating the air inlet channel with the air outlet channel and distributed successively. The three adjacent accommodation cavities include a first accommodation cavity, a second accommodation cavity and a third accommodation cavity. The first accommodation cavity is disposed between the second accommodation cavity and the third accommodation cavity. The second accommodation cavity is arranged adjacent to the air inlet channel relative to the first accommodation cavity. The third accommodation cavity is arranged adjacent to the air outlet channel relative to the first accommodation cavity. When the first accommodation cavity is expanding and inhaling air, the first accommodation cavity is communicated with the second accommodation cavity and the third accommodation cavity is closed. When the first accommodation cavity is contracting and discharging air, the first accommodation cavity is communicated with the third accommodation cavity and the second accommodation cavity is closed. According to the utility model, air inhaled from the air inlet channel can be discharged from the air outlet channel after travelling a comparatively long distance, the heat dissipation performance is improved and the heat dissipation area is enlarged. And the heat dissipating device becomes flexible in installation.
Description
[technical field]
The utility model relates to heat exchange field, and concrete is about a kind of heat abstractor.
[background technology]
The heat sink arrangement of correlation technique only has a host cavity, and gas is inhaled into host cavity, carries out heat exchange in this host cavity, absorbs the heat of target heat dissipation region, is then discharged from host cavity.The cooling region of this scheme is little, the limited location system of air-breathing and exhaust, and Installation Flexibility is little, and radiating effect is restricted.
Therefore, be necessary to provide a kind of new heat abstractor to address the above problem in fact.
[utility model content]
The utility model provides a kind of heat abstractor of better heat-radiation effect.
The purpose of this utility model is achieved in that
A kind of heat abstractor, it comprises inlet channel, outlet passageway and be communicated with described inlet channel and at least three host cavities that outlet passageway is arranged successively, appoint and get wherein three adjacent host cavities, described three adjacent host cavities comprise the first host cavity, the second host cavity and the 3rd host cavity, described the first host cavity is arranged between the second host cavity and the 3rd host cavity, described the second host cavity compared to the first host cavity near inlet channel setting, described the 3rd host cavity compared to the first host cavity near outlet passageway setting, when the first host cavity is in expansion breathing process, the first host cavity and the second host cavity are communicated with, the 3rd host cavity is closed, when the first host cavity is shrinking in exhaust process, the first host cavity and the 3rd host cavity are communicated with, and the second host cavity is closed.
Preferably, described host cavity is made by piezoelectric, realizes the enlargement and contraction of host cavity by the piezo-electric effect of piezoelectric.
Preferably, between described two adjacent host cavities, be provided with bindiny mechanism, described bindiny mechanism connects described two adjacent host cavities.
Preferably, described bindiny mechanism can independent assembly and disassembly.
Preferably, described bindiny mechanism can be gas communication passage.
Preferably, described bindiny mechanism can be the gas communication passage of bending.
The utility model has the advantage of: the heat abstractor that the utility model provides can make gas through longer propelling movement distance, discharge from outlet passageway from inlet channel sucks again, better heat-radiation effect, heat dissipation region is larger, installs more flexible.

[specific embodiment]
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1 to Figure 3, be the heat abstractor 100 that the utility model provides, it comprises inlet channel 10, outlet passageway 20 and is communicated with described inlet channel 10 and N host cavity 30(N >=3 that outlet passageway 20 is arranged successively, N round numbers).
At N host cavity 30, intercept arbitrarily wherein three adjacent host cavities, described three adjacent host cavities comprise the first host cavity 301, the second host cavity 302 and the 3rd host cavity 303, described the first host cavity 301 is arranged between the second host cavity 302 and the 3rd host cavity 303, described the second host cavity 302 arranges near inlet channel 10 compared to the first host cavity 301, and described the 3rd host cavity 303 arranges near outlet passageway 20 compared to the first host cavity 301.
Host cavity closure refers to that gas cannot pass through from this host cavity.
When the first host cavity 301 is in expansion breathing process, the first host cavity 301 and the second host cavity 302 are communicated with, the 3rd host cavity 303 closures.The closed gas of the 3rd host cavity 303 cannot pass through, and the first host cavity 301 can only suck gas from the second host cavity 302 1 sides, namely can be understood as described the first host cavity 301 and can only suck gas from inlet channel 10 1 sides.
When the first host cavity 301 is shrinking in exhaust process, the first host cavity 301 and the 3rd host cavity 303 are communicated with, the second host cavity 302 closures.The closed gas of the second host cavity 302 cannot pass through, and the first host cavity 301 can only be to the 3rd host cavity 303 1 side Exhaust Gas, and namely can be understood as described the first host cavity 301 can only be to outlet passageway 20 1 side Exhaust Gas.
Air-breathing and shrink exhaust process through the expansion of the first host cavity 301, gas pushes in the direction from inlet channel 10 1 sides to outlet passageway 20 1 sides.
Certainly the host cavity being directly connected with inlet channel may be discharged some gases from inlet channel when shrinking exhaust, the host cavity being directly connected with outlet passageway may suck some gases from outlet passageway when expansion is air-breathing, this belongs to the special circumstances of the host cavity at two ends, does not affect heat abstractor integral body pushes gas trend in the direction from inlet channel one side to outlet passageway one side.
Described host cavity 30 is made by piezoelectric, realizes the enlargement and contraction of host cavity 30 by the piezo-electric effect of piezoelectric, and the closure state of host cavity 30.Certainly, other embodiments that can be used for realizing host cavity 30 above-mentioned functions all should be included in the protection domain of recording in claims.
Preferably, heat abstractor 100 of the present utility model is provided with bindiny mechanism 40 between adjacent two host cavities in its N host cavity 30, and described bindiny mechanism 40 connects described two adjacent host cavities.
Described bindiny mechanism 40 can independent assembly and disassembly, if while making like this that wherein certain host cavity damages, can change easily.
Described bindiny mechanism 40 can be gas communication passage, and the gas communication passage of bending preferably.Make like this bindiny mechanism 40 can change the layout form of whole heat abstractor 100, make irregular shape, position adaptability is stronger.
The heat abstractor that the utility model provides can make gas through longer propelling movement distance, discharge from outlet passageway from inlet channel sucks again, better heat-radiation effect, and heat dissipation region is larger, installs more flexible.
The foregoing is only preferred embodiments of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; in every case the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or is changed, and all should include in the protection domain of recording in claims.
