🔷Solid State Cooler Product Overview
The TEC1-04904 is a standard 30x30mm semiconductor cooling module designed for a 4A current, with a maximum temperature difference of approximately 65–70°C and a cooling capacity of approximately 15–18W. This product is noise-free, vibration-free, and maintenance-free, and can switch between cooling and heating modes by reversing the current direction. With stable and reliable performance, it is suitable for low-power, precision temperature control applications such as beauty devices, medical equipment, and precision instruments.
🔷TEG Module Product Applications
1. Portable Cooling and Heat Dissipation: Among DIY enthusiasts and in some off-the-shelf products, it is often used to create cooling back covers for smartphones, effectively lowering device temperatures during gaming. At the same time, it serves as a core component in products such as compact car refrigerators and water dispensers, providing a quiet and flexible cooling solution.
2. Beauty and Medical Devices: A typical application of this product is in home beauty devices. It allows the device to switch between hot and cold therapy modes in a short time, delivering an “ice-cool” sensation and enhancing user comfort.
3. Temperature Control for Instruments and Optoelectronic Devices: Some micro-lasers require a constant temperature during operation to ensure stability and precision, and this cooling plate serves as a “guardian of frequency stability.” At the same time, it is widely used in telecommunications equipment, precision instruments, and automotive electronics to provide reliable heat dissipation for critical components. This has historical roots—as early as 1994, a product of the same model was designated as a national military standard for temperature control in aerospace and military equipment, and its reliability has been proven over the long term.
