摘要

在目前的研究中,提出了一种新的微尺度冷却系统模型。这种小型冰箱是通过在矩形玻璃的侧面雕刻通道和微型喷嘴来建模的。该系统使用氮气作为工作流体,能够在5秒内将温度从300K降至80 k。该模型由热交换器、喷嘴和膨胀罐三部分组成,冷却系统的所有部分都是固定的。在该模型中,给出了通过通道和喷管截面的压降,并利用这些信息得到了收敛发散型微喷管喉部高马赫数时的温度降。由于这种平面内微喷嘴的特点,通过在玻璃中的时间来模拟热交换,并报告了冷却系统的温度。

Heat transfer and fluid flow analysis of a novel micro-miniature cryocooler model
In the current study, a new model for micro-scale cooling systems is presented. The small-scale refrigerator is modeled by engraving channels and a micro nozzle on the sides of a rectangular glass. The system has the capability to reduce the temperature from 300K to 80 in 5 seconds using nitrogen as the working fluid. The model consists of three elements, heat exchanger, nozzle and expansion tank and all the parts of the cooling system is stationary. For this novel model, pressure drop through the channels and nozzle sections is presented and by using these information, temperature drop through the nozzle is obtained regarding the high Mach number at the throat of the convergence-divergence micro-nozzle. Due to the characteristics of this in-plane micro-nozzle, the heat exchange is modeled through the time in the glass, and temperature of the cooling system is reported.
