　　闭式循环无液氦稀释制冷机是实现100mK以下连续制冷的最有前景的制冷机候选方案之一。作为稀释制冷机的关键部件，蒸发器用于控制循环中氦-3-氦-4混合气体的循环速率和比例，预冷节流流体，并为稀释循环提供动力。氦-3-氦-4混合气体比例是直接影响循环效率的关键参数。薄膜燃烧器是控制蒸发器内气体比例的关键部件。因此，提出了一种新型蒸发器，采用环形孔道引导超流氦，并设置薄膜燃烧器与氦-4混合气体过滤器连接。确定了氦-3-氦-4摩尔浓度、蒸发器冷却功率、蒸发器热交换器初始参数等参数与蒸发器温度之间的综合关系。当蒸发器温度为700 mK时，薄膜燃烧器较普通孔板可提高蒸发器温度5.61%（0.39 mW）的制冷功率。研究结果为稀释制冷机蒸发器的性能优化和结构设计提供了参考，也为提高稀释制冷机蒸发器的整体制冷能力提供了指导。
