1、[Continuous Work] The semiconductor refrigeration fins do not need any refrigerant, the refrigeration fins can work continuously, there is no pollution source, no rotating parts, no rotation effect, no sliding parts are a piece, there is no vibration, noise, and long life , Easy to install. 2、[Cooling Heating 2 Functions] The semiconductor refrigeration sheet has two functions, which can be used for both cooling and heating. The cooling efficiency is generally 55~60%, but the heating efficiency is very high and always greater than 3、[High Accuracy Temperature Control] Through the control of input current, high accuracy temperature control can be achieved, with temperature detection and control means, it is easy to realize remote control, program control, and computer control to form a control system. 4、[Small Inertia Fast Cooling Heating Time] The thermal inertia of the semiconductor cooler is very small, and the cooling and heating time is very fast. When the hot end has good heat dissipation and the cold end is unloaded, the cooler can achieve the maximum in less than one minute. 5、[Power] The power of a single refrigeration part pair of the semiconductor refrigeration film is very small, but if it is combined into a pile. If the same type of pile is used in series and parallel to form a refrigeration system, the power can be made very large. 1 x Thermoelectric Cooler Item Type: Thermoelectric CoolerMaterial: Semiconductor Refrigeration MaterialModel: TEC1-12706Rated Voltage: DC12VMaximum Voltage: DC15V (Th=30℃)Maximum Current: 6A (U=15V, Th=30℃)Maximum Temperature Difference: 67℃(Qc=0,Th=30℃)Maximum Cooling Capacity: 51.4W (△T=0℃,Th=30℃)Internal Resistance: 1.8- 2.1ΩLead Specification: 20AWG, L=300mmPackaging Process: 704 Silicone Rubber SealingAssembly Pressure: 6kgWorking Temperature: -50~+80℃Storage Temperature: -40~+60℃
