• Features: Semiconductor refrigeration is one of those refrigeration know-how which produces damaging thermal resistance, which is characterised via way of non-moving components and excessive reliability. Suitable for small space cooling, semiconductor refrigeration studying theory, examine suggestions evolved cooling package planing. The cooling impact is dependent upon the scale of the cooling space, ambient temperature, adiabatic, sealing etc. Can be used as dual-core cooling, air cooling device, cooling equipment. Stable paintings and low noise, no refrigerant required. Specification: Material: aluminum + plastic fan Voltage: 220V Cooling core: 2* TEC1-12706 Length: 20cm / 7 Weight: Approx/57 Wiring method: V+: All purple wire (any V+ is ok) V-: All black wire(any V- is ok) L N: Power cable
