CENCO Reversible Thermoelectric Demonstrator
Reproduce the Same Energy Transfer That Powered Voyager Spacecraft
Capture the interest of your students with this amazing demonstrator. Even though the converter has no moving parts, the apparatus changes thermal energy into electrical energy or vice versa.
Series-connected semiconductor junctions are sandwiched between two aluminum legs. Immerse the legs in baths of different temperatures and electrical energy is produced, causing th motor and flywheel to spin. Generates approximately 10mV for each degree difference in temperature between legs-1000 times more voltage than a thermocouple device. The motor plugs into 4mm banana jacks and is removable so you can monitor voltage output directly with a multimeter.
To reverse the process and demonstrate refrigeration, connect a low voltage source (6VDC/2A) to the two banana jacks. One leg will heat up while the other cools. Under good conditions, a temperature different of up to 17℃ may be produced.
Include operating instructions, 2 insulated cups (8.6 diameter, 11cm high) and storage box that serves as a demonstration platform. Thermometer may be helpful to monitor the temperature changes. Unit is approximately 20cm tall.
熱電效應裝置
這是一個將熱能轉變為機械能或機械能轉變為熱能的裝置。
將一連續聯結半導體介面插入兩鋁片中。將兩鋁片插入溫度不同的
兩杯水內,產生機械能,而使此裝置上的輪子開始轉動。兩鋁片上一度
的溫差可產生10伏特的壓力,是熱電偶的100倍以上。
附有說明書,兩個杯子,一個儲存盒,可自備溫度計。
