The Research for Adsorptive Desiccant Dehumidifier Cooling System in Lithium Battery Dry Room Student:Pang-chin LiuAdvisor:Ay Su Institute of Mechanical Engineering, Yuan-Ze University ABSTRACT With the trend of light-weighted and small-packed on the portable electronics products, and the demand of prolonged energy at just one charge, as a component, lithium battery of light-small & high energy density are being requested to be crucial for modern life. Under the strict requisition for the qualified manufacturing of lithium battery, a circumstance of low humidity is definitely asked for. After studying several dehumidifier cooling systems, we adopt the honey-comb adsorptive rotary dehumidifier as the optimum way to meet thus demand. The honey-comb adsorptive rotary dehumidifier, with advantages such as maintaining a consistent low humidity at a period of time, dry air cooling down the after-cooler capacity etc., is recognized as the more energy-saving method when compared to a common-known refrigerate compressor dehumidifier. This device is just to discuss how honey-comb adsorptive rotary dehumidifier could reach the assumption of energy-saving and then is justified both by illustration & figure. Through the change of rotary speed, regeneration temperature etc., an optimum dew-point temperature could be acquired. Through a sound system design, we could change the relative temperature parameters and pressure factors to get an optimum function model. Furthermore, during a long period of observation and study, with evidence of a series of experiment procedures, figures and systematic drawings, a suitable dehumidifying device can come out for the special requirements for Lithium Battery Room. We also hope ideal dehumidifying devices can be designed for different areas of industries.
