5Pcs SP1848-27145 Heatsink 4.8V 669MA Features
-
SP1848-27145 4.8V 669MA semiconductor thermoelectric power generation
-
Can be used for power generation, cooling or heating applications, these modules are manufactured specifically for power generation
-
Model: SP1848-27145, Color: White, Lead Length: about 300mm, Size: 4x4x0.34 cm / 1.57x1.57x0.13 inch, Working Environment: -60~125℃, Temperature electromotive force (a): > 190x uV/ ℃, Conductivity: 850~1250Ω -1.cm-1, Thermal conductivity (K): 15~16x10-3-W/℃ cm.
-
The temperature difference will appear on both sides of the 12 volt power supply cooling chip. When one side is cold and one side is hot, do not energize the refrigerator for a long time without a radiator. Otherwise, the inside of the refrigerator will be overheated or burn.
-
When the thermal energy is discharged from the low temperature side through the thermoelectric power generation piece, part of the thermal energy flowing into the device does not exotherm, and becomes electric energy in the device, and outputs DC voltage and current.
