    製冷晶片的原理：\n\n                    主要利用半導體材料的帕爾帖(Peltier)效應，\n當直流電通過兩種不同半導體材料串聯成的電偶時，\n在電偶的兩端即可分別吸收熱量和放出熱量，可實現致冷的目的\n\n                     \n\n                    商品特色：\n\n                    ●無磨損，可連續工作，沒有滑動零件，是一種固體片件\n\n                    ●工作時沒有震動、噪音，壽命長、安裝容易且運行可靠、維護方便\n\n                    ●不使用製冷劑，不汙染環境\n\n                    ●體積小、重量輕，可大大節約建築面積\n\n                    ●冷卻速度快，其冷卻速度可通過調節工作電流來控制，便於手動和自動控制\n\n                    ●既能製冷又能製熱，只用一個片件就可以代替分立的製冷系統和加熱系統\n(製冷效率一般約55%~60%；製熱效率很高，永遠大於1)\n\n                    ●一般為有字面的為熱面、無字面的為冷面，但可通過改電流的方向反轉製冷及製熱面\n(改為紅線接電源負極，黑線接電源正極，則製冷片的冷熱面會對調)\n\n                    ●製冷片的熱慣性非常小，製冷製熱時間很快\n\n                    ※在熱端散熱良好，冷端空載的情況下，通電不到1分鐘，製冷片就能達到最大溫差\n\n                    ※製冷片是利用冷熱面的溫差進行製冷。所以熱面溫度越低，則冷面溫度更低，製冷效果就更好\n\n
