WHAT IT DOES: The SP1848-27145 semiconductor thermoelectric power generation chip can achieve cooling on one side and heating on the other side, making it very suitable for various DIY productions.
PRINCIPLE: Thermal energy flows into the thermoelectric generator from the high temperature side.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.
ADVANTAGE: No need for any refrigerant, can work continuously, no pollution source, no rotating parts, no rotating effect, no sliding parts, it is a solid piece, no vibration noise when working, long life, easy installation.
COOLING/HEATING: The semiconductor cooling chip has two functions, which can be used for cooling and heating can heat.The cooling efficiency is generally 55~60%, but the heating efficiency is very high and always greater than 1. Therefore, the use of a single piece can replace the separate refrigeration system and heating system.
FAST ACTION TIME: When the hot end has good heat dissipation and the cold end has no load, the maximum temperature difference can be reached in less than one minute after the heat sink is powered on.
USAGE: Place the side with characters on SP1848-27145 close to the heat dissipation surface (cold end), and the side without characters on the heat absorption surface (hot end).The red wire is connected to the positive electrode, and the black wire is connected to the negative electrode.
PRODUCTS INCLUDE: 4 x SP1848-27145 TEG Peltier Module;4 x Thermal silicone gasket.
