一种新型气体发生器的过滤冷却设计

摘要

为降低气体发生器燃气温度，提高气体清洁度，设计了一种迷宫式过滤冷却机构，相比传统过滤冷却方式，新设计的气体流通路径增加了280%，气体与吸热片接触面积增加了200%。验证试验结果表明迷宫式过滤冷却机构大大提高了气体的清洁度和降温效果。%　　Aimed at low temperature and high purity of gas for gas generator, a kind of labyrinth filter and cooling design of gas generator was proposed. Compared to the traditional way, the gas channel length of new design was increased 280%, and the contact area of gas and heat absorption pieces was increased 200%. The verificated test indicated the labyrinth filter and cooling design improves the purity and cooling effect of gas greatly.
