摘要:: 印刷电路板换热器作为一种新型的微通道换热器,具有紧凑高效、耐温耐压、可模块化等优势,在火箭发动机中具有很好的应用前景,但目前将印刷电路板换热器应用于火箭发动机的研究很少。对火箭发动机氦加热器提出了印刷电路板换热器的设计思路,开发了热力设计程序,并对其进行了数值模拟。结果表明:印刷电路板式氦加热器芯体具有较小的体积和质量,冷热侧温降的模拟值与计算值最大相对误差为1.33,冷热侧压降的模拟值与计算值之间的最大相对误差为18.51,证明了所开发的分段热力设计方法用于印刷电路板式氦加热器具有较高的准确性。氦加热器的冷端换热能力最强,热侧流体流动更加剧烈,换热能力更强,但同时也有更大的压降。

Abstract:: As a new type of micro-channel heat exchanger, the printed circuit heat exchanger has the advantages of compactness and efficiency, temperature resistance and pressure resistance, and modularity.It has a good application prospect in rocket engines, but there are few researches on the application of printed circuit heat exchanger in rocket engines.The design idea of printed circuit heat exchanger for helium heater applied to rocket engines was proposed, the thermal design program was developed and the numerical simulation was carried out.The results show that the printed circuit helium heater core has a small volume and mass, the maximum relative error between the calculated value and the simulated value of the temperature drop in the hot side and cold side of the helium heater is 1.33, and the maximum relative error between the calculated value and the simulated value of the pressure drop in the hot side and cold side of the helium heater is 18.51.It is demonstrated that the developed segmented thermal design method has high accuracy for printed circuit helium heater.The cold end of the helium heater has the strongest heat transfer capacity.The fluid flow on the hot side is more intense, and has a greater heat transfer capacity, but at the same time, there is a larger pressure drop.
