Features:
Semiconductor refrigeration is a kind of refrigeration technology which produces negative thermal resistance, which is characterized by non-moving parts and high reliability.
The cooling effect depends on the size of the cooling space, ambient temperature, adiabatic, sealing etc. 
Suitable for small space cooling, pet cooling, camping beverage storage box cooling, industrial materials cooling, etc
Surface large fins design, and two tube radiating, quick heat dissipation
Stable work and low noise, no refrigerant required.
