About This

• Provide students with an understanding of the basic principles of semiconductor refrigerators.
• Semiconductor coolers are generally divided into two sides, one side absorbs heat and the other side dissipates heat, which only plays a role in heat conduction. After power on, it can be cooled, and there is a temperature difference to generate electricity.
• The instrument is mainly composed of a refrigerator, a water tank, a fan, and two thermometers (self-provided).
• Appropriate physical activities and research are not only fun, but can also enhance students' observation skills, stimulate questions, and connect the content of the book with real life.
• Please feel to E-MAIL us if there are any problems and questions, we will try our best to
