本文提出了一种新的冷却循环,称为再冷却循环(RC)的系统与主动冷却,并演示了如何利用冷却剂的二次冷却,通过传递焓从冷却剂工作与间接增加冷却剂的冷却能力(散热器),在没有任何性质的改变冷却剂。介绍了其基本概念和工作原理;热力学循环分析的执行,以证明系统性能增益与RC比传统系统再生冷却。利用热力学原理,对RC进行了性能潜力分析;通过推演得到性能极限的表达式。以含RC的超燃冲压发动机为例,进一步揭示了RC的潜在性能。结果表明,RC具有很大的潜在性能和科学可行性。它可以增加冷却剂的散热器,并相应减少冷却剂的流量。此外,RC的输出功率可以为子系统提供能量供应。
This paper presents a new cooling cycle called Recooled Cycle (RC) for systems with active cooling and demonstrates how coolant could be utilized for secondary cooling through the transfer of enthalpy from coolant to work with an indirect increase in the coolant cooling capacity (heat sink), without any property change in the coolant. The basic concept and working principle are introduced; a thermodynamic cycle analysis is performed to demonstrate the system performance gains with RC over the conventional system with regenerative cooling. Using the principle of thermodynamics, performance potential analysis of RC is performed; expression of performance limit is obtained by deduction. Numerical analysis results further reveal the potential performance of RC taking scramjet engine with RC as the example. Results show that RC is with great potential performance and scientific feasibility. It can increase coolant heat sink and correspondingly reduce the coolant flow for cooling. In addition, the power output of RC could provide energy supply for subsystems.
