基于全板翅换热器溴化锂吸收式制冷机结构与性能研究

Structure and performance study of LiBr absorption chiller based on whole-plate-fin heat-exchanger

为了降低吸收式制冷机金属耗量 ,较小占用空间 ,提高制冷机传热传质性能 ,进而提高整机性能 ,在实验室建立了基于全板翅式换热器的溴化锂吸收式制冷机 ,并在设计上采用了专利技术。介绍了这种新型制冷机的设计思想和结构以及传热性能 ,并与管理壳式吸收式制冷机进行了比较。

In order to decrease the unit metal cost,reduce volume,improve the heat and mass transfer performance of chiller,a whole-plate-fin compact LiBr absorption chiller has been built up,which adopts patent technology of our lab.This paper introduces the design ideas,structure and heat transfer performance of the chiller,the whole-plate-fin chiller is compared with the tube-shell absorption one.
