TEC1-04903 DC5V Semiconductor Refrigeration Sheet Thermoelectric Temperature Electronic Refrigeration Ice Flake

Semiconductor refrigeration chip introduction Semiconductor refrigeration film is a kind of heat pump Its advantage is that there are no sliding parts and it is used in some occasions where space is limited reliability is high and there is no refrigerant pollution Utilize the Peltier effect of semiconductor materials When direct current passes through a galvanic couple of two different semiconductor materials in series the two ends can absorb heat and release heat respectively which can achieve the purpose of cooling It is a refrigeration technology that produces negative thermal resistance characterized by no moving parts and high reliability How to cool Get ready 5large sized object Cooling sheet radiator Thermal conductive silicone grease Heat insulation cotton Power SupplyThermal conductive silicone grease coated on refrigeration sheet The cooling surface of the cooling fin is installed on the radiator Turn on electricity cold noodles are beginning to cool Specification Model TEC1 04903Material ceramicRated voltage DC5VMax input current 3AInput power 15WCooling power 10 5WNumber of particle pairs 49Maximum temperature resistance 200℃Conductor internal resistance 1 7ΩMaximum temperature difference 60℃Lead specification 22 L 125mmAssembly pressure 2kgWorking environment 60℃Packaging process 704 silicone rubberStorage conditions 40℃ 60℃ 20 90 RhSize 20x20x3 7mmOperational feature one side cold the other side fever the red line is positive that i
