Introduction of Thermoelectric Cooler:
Thermoelectric cooler 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 effect for Peltier of semiconductor.

When direct current passes through a galvanic couple formed by two different semiconductor materials in series, the two ends of the galvanic couple can absorb heat and release heat respectively, which can realize cooling. It is a refrigeration technology that produces negative thermal resistance. It is characterized by no moving parts and high reliability.

Semiconductor Heat Dissipation Instructions:
-The side with words is the cool side, the side without words is the heat dissipation side. When working, the heat dissipation side must be dissipated, and it is strictly forbidden to energize without heat dissipation.
- A heat sink or water-cooling device must be installed on the heat dissipation side, otherwise it will burn out.
- To install a heat sink, apply thermal grease (not included).

Applications:
- High-tech field
- Home appliance application
- Electronic technology
- Industrial application
- Medical industry
- Chip cooling
- Dehumidification products
- Fresh products
- Communications industry

Precautions:
- Tested with no heat dissipation, there will be a cooling effect when it turns on. The power supply should be unplugged immediately within 1 second to prevent the cooler from burning.
- There is a cool side and a hot side. Never energize the refrigerator for a long time without a heat sink.
