12V 4-Chip Semiconductor Cooler for DIY Air Cooling, Small Space & Pet AC Use (6 Pin)

Efficient Thermoelectric Cooling: This 12V DC semiconductor cooler uses four high-performance Peltier chips to deliver active heat transferideal for compact enclosures, DIY refrigeration projects, and low-power pet cooling setups; performance scales with proper insulation, ambient temperature control, and consistent water circulation for heat dissipation.
Compact & -to-Install Design: Measuring just 12 x 6.6 x 9.5 cm (4.72 x 2.60 x 3.74 in) and weighing 611g, it fits tight spaces without modification; includes red (+) and black () s for straightforward wiringno extra adapters or controllers needed for basic 12V operation.
Water-Cooled Heat Dissipation: Unlike fan-only units, this device relies on external water circulation to remove heat from the hot sideensuring stable operation and avoiding thermal shutdown; never power on without active water , as dry operation risks immediate chip damage.
Flexible Power & Scalable Options: Supports two configurations280W at 12V/24A (4-chip) or 420W at 12V/36A (6-chip optional); standard 12V power supplies used in vehicles, labs, and hobbyist electronics Mean Well GST series, DPS-280AB, and similar regulated DC sources.
E onal & Practical Application: Designed for hands-on learning of thermoelectric principles, it serves as a functional core in custom chillers, mini incubators, beverage coolers, and prototype climate systems; includes only the cooler unittubing, pump, reservoir, and controller sold separately.
