Feature:1. Can Work Continuously: Without any refrigerant, can work continuously, there is no pollution source, not rotating parts, and not rotation effect.2. Solids Piece: There is no sliding part, is a solids piece, there is non vibration, noise, long life, and easy to install.3. Application: Widely used for water dispensers, automobile refrigerators, household freezers, and instruments, meters, lasers, infrared, high speed computers, telecommunications, medical, petrochemical and other industries.4. Fast Refrigeration Speed: Fast refrigeration speed, large temperature difference, high heat conversion efficiency, compact structure, convenient use and non pollution.5. 2 Functions: This is a semiconductor refrigeration chip with 2 functions, both cooling and heating.Specification:Item Type: Cooling Plate ModuleModel: TEC1-12706Material: CeramicUses: Widely used for water dispensers, automobile refrigerators, household freezers, and instruments, meters, lasers, infrared, high speed computers, telecommunications, medical, petrochemical and other industriesSize: Approx. 40 x 40 x 3.75mm / 1.57 x 1.57 x 0.15inInternal Resistance: 2.1~2.4Ω (Ambient Temperature 23±1℃, 1kHZ Ac Test)Large Temperature Difference: △Tmax(Qc=0) Above 59℃Working Current: Imax=4.3-4.6A (at Rated 12V)Rated Voltage: 12V (Vmax: 15V Starting Current 5.8A)Cooling Power: Qcmax 60-72WWorking Environment: Temperature Range -55℃~83℃ (Too high ambient temperature drop directly affects cooling efficiency)Package List:1 x Cooling FilmNote:There will be a temperature difference between the 2 sides of the cooling plate connected to a 12 volt power supply. One side is cold and the other side is hot. Do not power on the refrigerator for a long time without a radiator, otherwise will cause the inside of the refrigerator to overheat and burn.
