摘要
为了解决高热流密度器件的散热问题而设计一种带有强化冷凝段的热管散热器,模拟不同的运行工况,对其散热效果进行了数值计算,并与其他类型的热管散热器进行了比较。结果表明:新型散热器由于热管设计结构的改变,使其换热温差增大,而且使散热器底板的均温效果更好,可以有效地降低高热流密度器件的工作温度。
In order to solve the problem of heat dissipation of high heat flux equipments, a new type of radiator with heat pipes in both bottom plate and fin was designed. Simulation was carried out under different conditions, numerical calculation was done with its cooling effect, and the comparison was done with other types of heat pipe radiator. The results show that： this new type of heat pipe radiator can improves the temperature differences of heat transfer, because of the change of the heat pipes on struc- ture and the temperature of the bottom plate of the radiator more uniform, the operating temperature of the equipments with high heat flux can be reduced effectively.
