摘要
为解决某高热耗密闭设备散热问题,设计一种高效气液散热装置,其内循环提供冷却风为设备内部电子器件散热,外循环冷却液为内循环风降温带走系统热量。通过计算确定换热器的流程、翅片数量、间距等参数,最终确定气液换热装置结构。针对设计的气液换热装置设计模拟热源实验,验证换热装置的热性能。实验结果与计算结果相吻合,表明该换热装置设计可行,符合技术要求,设计方法可为同类换热装置的设计提供参考和技术支撑。
In order to solve the heat dissipation problem of a closed equipment with high heat consumption,an efficient gas-liquid heat exchange device was designed.The internal circulation provides cooling air for the heat dissipation of the electronic devices inside the equipment,and the external circulation coolant cools the system for the internal circulation air.The structure of the gas-liquid heat exchanger was determined by calculating the flow,the number of fins,the spacing and other parameters of the heat exchanger.The simulated heat source experiment is designed to verify the thermal performance of the designed gas-liquid heat exchanger.The experimental results are in agreement with the calculated results,indicating that the design of heat exchanger is feasible and meets the technical requirements.The design method can provide reference and technical support for the design of similar heat exchanger.
