Abstract
This utility model relates to heat abstractor, particularly a kind of Novel fin flow passage structure.The flow passage structure that this utility model provides is divided at least two flow path portion along its length, fin in the flow path portion of air inlet is spaced at greater, therefore the flow path portion flow resistance of air inlet reduces, in the case of not changing fan power, the intake in whole fin runner and wind speed can be effectively improved relative to original flow passage structure；Simultaneously, owing in the flow path portion the closer to flow passage structure air outlet, fin interval is the least, so its number of fins is the most, the flow path portion that air inlet goes out relatively, which increase the contact surface of runner fin and cooling air, further enhancing radiating effect, by this structure, same in the case of not changing fan power, can effectively reduce the maximum temperature (typically can have maximum temperature at the heater members at fin runner air outlet) of heater members.
Description
Technical field
This utility model relates to heat abstractor, particularly a kind of Novel fin flow passage structure.
Background technology
Due to the restriction of some equipment (such as phased-array radar) complete machine structure layout, dissipate to be reached for heater members simultaneously
, often there is the rectangular fin runner needing to apply air inlet, air outlet in both ends of the surface in heat and the demand of complete machine space structure
Carry out situation about dispelling the heat；When specifically applying, rectangular fin runner is arranged with heater members parallel contact, by rectangular fin stream
Road air outlet installs a fan so that cooling air enters from air inlet, from the cooling air of rectangular fin runner process by position
Heat in thermal conductive contact face heater members is taken away, but the runner of this rectangle is compared with general runner, has a disadvantage in that
The path that cooling air flows through fin is longer, and flow resistance is relatively big, causes the wind speed of whole fin runner to be difficult to improve, and then cause
The highest the closer to outlet cooling air temperature, the cooling-down effect near air outlet part is substantially weaker than the part fall near air inlet
Temp effect, whole fin runner uniform temperature is poor, the best near the heater members radiating effect of radiating fin runner air outlet part,
The fin runner having this flow passage structure is caused can not well to realize heat sinking function.
Utility model content
Goal of the invention of the present utility model is for the longer rectangular fin runner of length owing to air flows through fin
Path is longer, and flow resistance is relatively big, causes and is substantially reduced by the cooling air wind speed of fin runner, air quantity, thus is caused whole
Fin runner uniform temperature is poor, near the problem that the heater members radiating effect of radiating fin runner air outlet part is the best, it is provided that
A kind of flow resistance is less, the fin flow passage structure that runner uniform temperature is good.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of Novel fin flow passage structure, described flow passage structure includes flow passage cover plate, runner base plate and is positioned at stream

Directly；The two ends of flow passage structure are respectively air inlet and air outlet；Described air inlet or air outlet end are provided with a fan,
For cooling air is blown into or in suction passage；
Described flow passage structure is the most at least divided into two flow path portion, fin interval difference in each flow path portion, its
In, the closer to the flow path portion of air inlet, the interval between fin is the biggest.Concrete, as required flow passage structure can be divided into 2
Flow path portion, 3 flow path portion, even 8 flow path portion of 4 flow path portion, the flow path portion of division is the most, the most whole flow passage structure not same district
The uniform temperature in territory is the best.
Preferably, in some embodiments, described flow passage structure is uniformly divided into three flow path portion along its length, the most close
The flow path portion of air inlet is low-temperature zone, and the flow path portion near air outlet is high temperature section, the stream between low-temperature zone and high temperature section
Road portion is middle-temperature section；Fin interval in described low-temperature zone is more than the fin interval in middle-temperature section, the fin in described middle-temperature section
Interval is more than the fin interval in high temperature section.
Further, described flow passage cover plate and/or runner base plate are the thermal conductive contact face contacted with heater members.
Further, in two adjacent flow path portion, the fin interval in the flow path portion that fin interval is big is fin interval
2 times that in little flow path portion, fin is spaced.
Further, by being initial from air outlet, the fin arranging different length realizes fin in different flow path portion
The difference at interval.
In certain embodiments, compared with prior art, can select to will be closest to the flow path portion at air outlet (generally
High temperature section) in fin interval keep constant, the most compared with prior art, (the highest near the flow path portion at air outlet
Temperature section) in number of fins constant, and from one section of flow path portion before high temperature section, expand the wing in follow-up flow path portion successively
(i.e. one section of flow path portion before high temperature section starts to reduce the number of fins in each flow path portion successively, thus realizes at sheet interval
The increase at fin interval), advantage of this is that, achieving, increase the purpose of fin runner intake, it is achieved whole runner
While the more preferable uniform temperature of structure, along with the expansion at fin interval in some flow path portion along flow channel length, it is meant that wherein
The minimizing of the number of fins arranged, so that the weight of whole fin runner is reduced, quicker to device weight at some
In the equipment of sense, such as phased-array radar, on the premise of the constant even lifting of each device performance, the reduction of complete machine weight has non-
On the premise of the most important meaning, i.e. this utility model can realize improving fin runner heat dispersion, reduce device weight further
Amount, significant.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
The Novel fin flow passage structure that this utility model provides, compared with prior art, this utility model provides
Flow passage structure is divided at least two flow path portion along its length, and the fin in the flow path portion of air inlet is spaced at greater,
Therefore the flow path portion flow resistance of air inlet reduces, and in the case of not changing fan power, can have relative to original flow passage structure
Effect improves the intake in whole fin runner and wind speed；
Simultaneously as the least the closer to fin interval in the flow path portion of flow passage structure air outlet, so its number of fins is just
The most, that relative air inlet goes out flow path portion, which increase the contact surface of runner fin and cooling air, further enhancing
Radiating effect, by this structure, equally in the case of not changing fan power, can effectively reduce the highest temperature of heater members
Degree (typically can have maximum temperature at the heater members at fin runner air outlet).
