摘要
针对舰载/车载阵面内部模块高度集成化、冷却与结构深度耦合的发展趋势,阐述了一种基于结构与冷却融合设计的阵面热控制方案。通过将流体分配器与阵面骨架融合为一体,实现冷却与结构深度耦合;采用阵面骨架分水静压腔设计和额定流量下流阻匹配技术,实现阵面内各液冷模块流量的精确分配;采用微小流道叠加局部截断的强化传热技术,实现了子阵模块内热流密度为105 W/cm^(2)功率器件的有效散热和同类型主要发热器件的安装表面温度差值不得大于5℃的均温性热控制要求。通过在实装子阵模块嵌装温度传感器,监测冷板表面温度,验证了热控制方案的合理性与可行性。
In view of the development trend of highly integrated modules and deep coupling between cooling and struc-tural design within ship-borne/vehicle-borne arrays,this paper describes a thermal control scheme for arrays based on the in-tegration of structural and cooling design.By integrating the fluid distributor with the array framework,a deep coupling between cooling and structural design is achieved;The design of water-distribution static-pressure chamber within the array skeleton and the flow resistance matching technology under rated flow are adopted to achieve precise distribution of fluid flowing to the cooling modules within the array;The heat transfer enhancement technology of superimposing micro-flow channels and local truncation is adopted to achieve effective heat dissipation for power devices with a heat flux density of 105W/cm^(2) within the sub-array module,and to meet the thermal control requirement of maintaining a temperature difference of no more than 5℃ between the installation surfaces of similar major heat-generating devices.By embedding temperature sensors in the actual sub-array modules,the surface temperatures of cold plates are monitored to verify the rationality and feasibility of thermal control schemes.
