Abstract
The invention relates to cooling devices, in particular to a novel cooling fin runner structure. The runner structure is divided into at least two runner parts in the length direction, intervals between fins in the runner part close to an air inlet are larger, and therefore the flow resistance of the runner part at the air inlet is reduced, and under the situation that the fan power is not changed, the supply air rate and the air speed in the whole fin runner can be effectively increased relative to an original runner structure; meanwhile, due to the fact that the closer the fins in the runner part are to the air outlet of the runner structure, the smaller the intervals of the fins are, the number of the fins is relatively large, and relative to the runner part at the air inlet, the contact surface of the runner fins with cooling air is increased, and the cooling effect is further enhanced. By means of the structure, under the situation that the fan power is not changed, the highest temperature (generally, a heating device close to the air outlet of the fin runner will have the highest temperature) of the heating device can be effectively reduced.
Description
Technical field
The present invention relates to heat abstractor, particularly a kind of Novel fin flow passage structure.
Background technology
Restriction due to some equipment (such as phased-array radar) complete machine structure layout, in order to be reached for heater members heat radiation and the demand of complete machine space structure simultaneously, often occur needing applying air inlet, air outlet to carry out situation about dispelling the heat at the rectangular fin runner of both ends of the surface；When specifically applying, rectangular fin runner is arranged with heater members parallel contact, by installing a fan at rectangular fin runner air outlet, cooling air is entered from air inlet, the heat that will be located in thermal conductive contact face heater members from the cooling air of rectangular fin runner process is taken away, but the runner of this rectangle is compared with general runner, have a disadvantage in that cooling air flows through the path of fin longer, flow resistance is bigger, the wind speed causing whole fin runner is difficult to improve, and then cause the closer to outlet cooling air temperature the highest, cooling-down effect near air outlet part is substantially weaker than the partial warm down effect near air inlet, 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.
Summary of the invention
The goal of the invention of the present invention is that the path flowing through fin due to air for the rectangular fin runner that length is longer is longer, flow resistance is bigger, cause and be substantially reduced by the cooling air wind speed of fin runner, air quantity, thus cause whole fin runner uniform temperature poor, near the problem that the heater members radiating effect of radiating fin runner air outlet part is the best, there is provided a kind of flow resistance less, the fin flow passage structure that runner uniform temperature is good.
To achieve these goals, the technical solution used in the present invention is:
A kind of Novel fin flow passage structure, described flow passage structure includes flow passage cover plate, runner base plate and the fin multiple parallel to each other between flow passage cover plate and runner base plate, and described fin is vertical with described flow passage cover plate and runner base plate；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 being blown into or in suction passage by cooling air；
Described flow passage structure is the most at least divided into two flow path portion, and fin interval difference in each flow path portion, wherein, the closer to the flow path portion of air inlet, the interval between fin is the biggest.Concrete, can as required flow passage structure 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, and the uniform temperature of the most whole flow passage structure zones of different is the best.
Preferably, in some embodiments, described flow passage structure is uniformly divided into three flow path portion along its length, and wherein the flow path portion near air inlet is low-temperature zone, and the flow path portion near air outlet is high temperature section, and the flow path portion between low-temperature zone and high temperature section is middle-temperature section；Fin interval in described low-temperature zone is more than the fin interval in middle-temperature section, and the fin interval in described middle-temperature section 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 2 times that in the flow path portion that fin interval is little, fin is spaced.
Further, by being initial from air outlet, the fin arranging different length realizes the difference at fin interval in different flow path portion.
nullIn certain embodiments，Compared with prior art，The fin interval that will be closest in the flow path portion (generally high temperature section) at air outlet can be selected to keep constant，The most compared with prior art，Constant near the number of fins in the flow path portion (generally high temperature section) at air outlet，And from one section of flow path portion before high temperature section，(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 to expand the fin interval in follow-up flow path portion successively，Thus realize the increase at fin interval)，Advantage of this is that，Achieving，Increase the purpose of fin runner intake，While realizing the more preferable uniform temperature of whole flow passage structure，Along with the expansion at fin interval in some flow path portion along flow channel length，Mean the minimizing of the number of fins arranged wherein，So that the weight of whole fin runner is reduced，In some equipment more sensitive to device weight，Such as phased-array radar，On the premise of the constant even lifting of each device performance，The reduction of complete machine weight has very important meaning，On the premise of i.e. the present invention can realize improving fin runner heat dispersion，Reduce device weight further，Significant.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
The Novel fin flow passage structure that the present invention provides, compared with prior art, the flow passage structure that the present invention 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.
