🔷Thermoelectric Generator Product Overview
The TEC1-19505 is a flagship semiconductor cooling module designed for cooling applications requiring extremely large surface areas, ultra-high power, and high voltage density. measuring 30 × 60 mm. Featuring a large, rectangular, symmetrical package design, it provides an exceptionally generous heat exchange area and is optimized for equipment requiring extensive temperature control and handling extremely high thermal loads—such as ultra-high-power industrial laser modules, large-scale high-power industrial equipment, and high-performance medical devices.
This product is available in three crystal configurations—K10, K12, and K14—with thicknesses of 3.4 mm, 3.6 mm, and 3.8 mm, respectively, corresponding to maximum cooling temperature differences of 60°C, 65°C, and 70°C (under conditions where the hot-end temperature Th = 40°C). It features a maximum voltage of 24.0 V, a maximum current of 5.0 A, a maximum cooling power of 96 W, and an internal resistance of 3.74 Ω.
The extra-large 30×60 mm rectangular package allows it to be embedded within ultra-high-power laser modules, large industrial equipment, and other applications. While ensuring a maximum cooling temperature difference of 70°C and ultra-high cooling power of 96W, the 30 mm width and 60 mm length provide an extremely generous heat exchange area, helping to evenly distribute cooling capacity across the large surface area of the load. This product features a 24V high-voltage, 5.0A current drive design, making it highly compatible with common industrial power supplies (24V) and telecommunications equipment power platforms. The low internal resistance of 3.74Ω effectively controls Joule heating loss (I²R ≈ 93.5W) at 5.0A, allowing more electrical energy to be converted into effective cooling capacity and delivering outstanding energy efficiency. The substrate utilizes a sintered process combining 96% alumina ceramic (0.76 mm) and 0.4 mm oxygen-free copper; the relatively thick copper layer ensures uniform heat dissipation across the 60 mm × 30 mm ultra-large surface area. It comes standard with 20 AWG silicone rubber leads (200 mm in length), capable of safely carrying a 5.0 A current. The 704 is sealed around the perimeter with silicone rubber, providing excellent moisture, dust, and shock resistance. Its all-solid-state construction ensures precise operation with zero noise and zero vibration.
This product is typically used in applications such as temperature control for ultra-high-power industrial laser modules, heat dissipation for large-scale industrial equipment, high-performance medical devices, and high-power communication base stations. It is the flagship choice for ultra-high-power-density cooling requirements in very large-area spaces.

🔷Thermoelectric Cooler Peltier Operation Principle
The TEC1-19505 utilizes the Peltier effect to achieve thermoelectric cooling. At its core, multiple pairs of P-type (Bi₂Te₃-Sb₂Te₃ hole-type) and N-type (Bi₂Te₃-Bi₂Se₃ electron-type) semiconductor grains are connected in series via metal bus bars to form a thermoelectric stack, which is sandwiched between two layers of highly thermally conductive ceramic substrates. With 195 pairs of crystals, this is an ultra-large-scale thermoelectric stack design featuring an extremely high number of thermocouple pairs, capable of generating a significant temperature difference and cooling capacity at moderate current levels.
When a forward DC voltage (up to 24.0 V) is applied, a 5.0 A current drives carriers to exchange energy at the PN junction interface—the cold end absorbs phonon energy and cools, while the hot end releases energy and heats up. Heat is continuously “pumped” from the cold end to the hot end.
The low internal resistance of 3.74 Ω effectively controls Joule heating loss (I²R ≈ 93.5 W) at a current of 5.0 A. The 0.4 mm thick copper layer helps evenly dissipate the high heat load of 96 W across the extra-large 60 mm × 30 mm surface area. This product achieves a maximum temperature difference of 70°C at a hot-end temperature of 40°C (K14 model), while the cold end can reach as low as approximately -30°C.
