Feature:1. A solid piece without vibration, noise, possess long life and easy installation. Can work continuously does not need any refrigerant, there is no pollution source or rotating parts, no rotation effect, no sliding part2. Semiconductor refrigeration film have two functions, both cooling and heating3. The product is a current‑transducer type chip. High‑accuracy temperature control can be realized through the control of the input current. Coupled with temperature detection and control means, it is easy to realize remote control, program control, and computer control to form an automatic control system4. The thermal inertia is very small, and the cooling and heating time is very fast, the cooling fin will the maximum temperature difference in less than one minute when the hot end has good heat dissipation and the cold end is empty5. Reverse use of semiconductor refrigeration fins is thermoelectric power generation. Semiconductor refrigeration fins are usually suitable for power generation in the middle and low temperature areasSpecification:Item Type: Thermoelectric Cooler ModuleModel: TEC1-12705Material: Ceramic + semiconductorPurpose: CoolingWire Specification: Wire Length: Approx. 100mm / 3.9in ±5mm, RV standard wire, single head approx. 5mm / 0.2in with tin platedInternal Resistance: 2.4~2.7Ω (ambient temperature 23±1℃, 1kHZ Ac test)Dimension: Approx. 40 x 40 x 3.6mm / 1.6 x 1.6 x 0.1inMaximum Temperature Difference: ΔTmaximum(Qc=0)>61℃Working Current: Imaximum=5A (when the rated voltage starts)Rated Voltage: DC12V (Vmaximum: 15.4V)Cooling Power: Qcmaximum 45WAssembly Pressure: 85N/cm²Working Environment: Temperature range -65℃～67℃ (too high ambient temperature will directly affect the cooling efficiency)Ambient Temperature: -10℃～40℃How to Use: 1.
