🔷Cooling Module Performance Curve
🔷Tec Thermoelectric Cooler Product Overview
The TEC1-04910 is a 25x25mm semiconductor cooling module designed for high current (10A) operation, with a maximum temperature difference of approximately 65–70°C and a cooling capacity of approximately 45W. This product is noise-free, vibration-free, and maintenance-free; it can switch between cooling and heating modes by reversing the current direction. With its powerful performance, it is suitable for high-efficiency cooling applications such as automotive refrigerators, laser cooling, and high-power electronic equipment.
🔷Semiconductor Cooler Work Principle
⚛️ Core Principle: From Physical Effects to Practical Cooling
1.Physical Basis: When a direct current passes through a circuit composed of two different conductors, one junction absorbs heat and cools, while the other releases heat and warms up—this is known as the Peltier effect. The key is that reversing the current direction causes the hot and cold ends to switch places.
2.Semiconductor Materials Are Key: The Peltier effect in ordinary metals is very weak and has no practical value. In contrast, P-type and N-type semiconductor materials produce a much stronger effect, making them the ideal core materials for cooling elements.
3.Internal Structure: Inside the TEC1-04910, P-type and N-type semiconductor blocks are arranged alternately. They are connected in series via conductive metal strips to form a circuit and are sandwiched between two heat-conductive, insulated ceramic plates.
🔁 Operating Principle: A Microscopic “Heat Transporter”
1.Once powered, the hot and cold ends are separated: When a direct current is applied, electrons and holes (charge carriers in the semiconductor) move in a specific direction driven by an electric field.
2.Cold End Absorbs Heat: At one junction, charge carriers transition from a lower energy level to a higher one; this process requires absorbing heat from the external environment, making this point the cold end.
3.Hot End Releases Heat: At the other junction, charge carriers return from a higher energy level to a lower one, releasing heat in the process; this point becomes the hot end.
4.Continuous Heat Transfer: In this way, heat is continuously “transferred” from the cold end to the hot end. The heat from the hot end is then dissipated via a heat sink, allowing the cold end to remain at a low temperature.
