Abstract

This paper presents the design of a partially heated Vapor Chamber (VC) system utilizing a passive cooling technique, analyzed under various inclination angles. The Finite Volume Method (FVM) is utilized to compare the results with experimental measurements conducted. Additionally, all results obtained with the tested VC are compared to a copper plate of identical dimensions to demonstrate the VC’s impact on thermal management issues. The dimension of the copper VC is established as 56 × 56 mm2. Two distinct partial heating dimensions at the evaporator block, measuring 10 × 10 mm2 and 20 × 20 mm2, are evaluated under various heat flux loads. The study is further expanded to include varying temperatures between the evaporator block and the condenser block. While a chiller controls the temperature on the condenser block side, the power supply to the evaporator block is adjustable to facilitate heating. The inclination angle of the system is identified as an additional parameter for investigation, as it may influence the thermal performance of the vapor chamber due to gravitational effects. At the conclusion of the study, significant results indicated that a higher thermal resistance value was observed for a heating area of 10 × 10 mm2 for both VC and copper plate. The comparison between the copper plate and VC indicates a 7 % reduction in thermal resistance with VC across both selected heating areas. Furthermore, a higher temperature that increases proportionally with heat flux is observed in the case of the copper plate. The effect of inclination appears to be negligible for the parameters examined.
蒸发室的热性能:部分加热,中心有不同的加热区域,并有实验装置的数值分析支持
本文介绍了利用被动冷却技术设计的部分加热蒸气室(VC)系统,并在不同倾角下进行了分析。利用有限体积法(FVM)将结果与实验测量结果进行比较。此外,还将测试的 VC 得出的所有结果与相同尺寸的铜板进行了比较,以证明 VC 对热管理问题的影响。铜制 VC 的尺寸确定为 56 × 56 mm2。在不同的热通量负载下,对蒸发器区块的两个不同的局部加热尺寸(10 × 10 mm2 和 20 × 20 mm2)进行了评估。研究范围进一步扩大,包括蒸发器区块和冷凝器区块之间的不同温度。冷却器控制冷凝器块一侧的温度,而蒸发器块的电源则可调,以便于加热。系统的倾斜角度被确定为一个额外的研究参数,因为它可能会因重力效应而影响蒸发室的热性能。研究结果表明,在加热面积为 10 × 10 平方毫米时,VC 和铜板的热阻值较高。铜板和 VC 之间的比较表明,在两个选定的加热区域内,VC 的热阻都降低了 7%。此外,在铜板上还观察到温度随热流量成比例地升高。在所研究的参数中,倾斜度的影响似乎可以忽略不计。
