To deal with multi-heat-source and high-heat-flux heat transfer problem of array antennas, a heat pipe cold plate equipment is developed. Acetone-aluminum heat pipe construction consists of eight vertical pipes with their upper condensation section and lower evaporation section connected with each other. Evaporation section is embedded in the aluminum-made cold plate and condensation section is cooled by cooling water in water-jacket. Eight electronic-heating plates are evenly arranged on the two bigger vertical surfaces to simulate heat generation of array antennas and the heat is eventually transferred to cool water and then to outer environment. Experimental study shows that the heat pipe cold plate equipment possesses excellent heat transfer performance and temperature evenness, and satisfies design requirements.

To solve cooling problem of array arrangements of travelling wave tubes with high heat dissipation power,high heat flux and multiple heat sources,a new cold plate equipment embedded with heat-pipes is designed.The startup performance,isothermal performance and heat transfer characteristics of the newly-designed heat pipe cold plate under different total heating power,different cooling water flux and different filling mass when working under big tilt obliquities(60°≤θ≤90°) are experimentally studied.Experimental results indicate that the heat pipe cold plate startups within 3—15 minutes and isothermal performances under P=1600W and Q>300L/h cannot meet the cooling object.Under different total heating power(1600W300L/h,the maximum temperature differences on the cold plate wall are less than 10℃(ΔT_(max)<10℃), the maximum temperatures of the cold plate wall are less than 70℃(ΔT_(max)<70℃) and the total thermal resistances are less than 0.01℃/W(R_(th)<10℃/W).To make full use of the new designed heat pipe cold plate,cooling conditions in condense segment and corresponding heating conditions in evaporation segment must be managed.Total thermal resistance increases with the increase of tilt obliquity within the experimental tilt obliquity range.When total heating power P or cooling water flow rate Q increases,heat transfer performance of the heat pipe cold plate is enhanced and R_(th) decreases under experimental tilt obliquities.

针对在受限空间内工作的行波管阵列所面临的多热源、高热流密度、高散热功率冷却问题,研制了一种新型热管冷板.在自行设计建立的试验台上,对新型热管冷板在大倾角下(60°≤θ≤90°)工作时的传热性能进行了系统的试验研究.试验结果表明,在不同加热总功率P(1600—4000W)和不同冷却水流量Q(100—400L/h)下,热管冷板均能在3—15m in内正常起动.除了P=1600W、Q>300L/h情况下的冷板均温性不能符合行波管冷却要求外,其余试验工况下冷板壁面的最大温差ΔTmax<10℃,冷板壁面的最高温度ΔTmax<70℃,热管冷板的总热阻<0.01℃/W,表明新型热管冷板具有优异的均温高效传热性能.为了有效地发挥新型热管冷板的均温高效散热性能,必须保证其在匹配的冷凝段冷却条件和蒸发段加热条件下工作.在试验的倾角范围内,随着倾角的增大,热阻单调递增;冷却水流量增大或加热功率增加时,热管冷板的换热增强,热阻减小.
