Product Description The Thermoelectric Peltier Refrigeration Cooling System DIY Kit is a high-performance solid-state cooling solution designed for small-space air conditioning and electronic component cooling. Utilizing the powerful TEC1-12706 Peltier module, this kit functions by creating a significant temperature differential across its ceramic plates when 12V DC is applied. The assembly includes a large primary heat sink and a 90mm fan to dissipate heat from the "hot side," while a smaller heat sink and dedicated 40mm fan efficiently circulate chilled air from the "cold side." This pre-assembled kit is perfect for DIY pet house coolers, mini-refrigerators, medical insulin coolers, and laser diode temperature stabilization.

Key Features

  • Complete Cooling Solution: Includes the Peltier chip, two aluminum heat sinks, dual fans, and protective grilles for an out-of-the-box cooling experience.

  • Solid-State Reliability: No moving parts inside the cooling mechanism (excluding fans) means no vibration, no noise, and no refrigerant gases, making it eco-friendly.

  • Rapid Chill Performance: Capable of dropping the cold-side temperature significantly below ambient within minutes when properly insulated.

  • High-Efficiency Heat Dissipation: Large-surface-area aluminum fins paired with a high-flow 12V fan ensure the hot side remains within safe operating limits to maximize cooling delta.

  • Versatile Application: Compact footprint allows it to be integrated into incubators, PC cases, or small insulated boxes (up to 10 liters).

Technical Details

  • Thermoelectric Module: Features the TEC1-12706, an industrial-grade bismuth telluride based Peltier device with 127 couples.

  • Dual Fan Configuration: Large 12V fan handles the critical heat dissipation, while the small 12V fan prevents frost buildup by circulating air over the cold fins.

  • Heat Sink Design: Multi-fin extruded aluminum blocks maximize the contact surface area for both heat extraction and cold emission.

  • Thermal Interface: High-conductivity thermal grease pre-applied between the Peltier chip and heat sinks for minimum thermal resistance.

  • Wiring Setup: Simple two-wire configuration for the Peltier chip (Red +, Black -) and standard 2-pin connectors for the fans.

  • Current Management: Requires a stable 12V DC power source; the Peltier chip draws ~5A while fans draw ~0.2A each.

  • Cold Transfer: The cold side block is designed to be isolated from the hot side via a foam or plastic gasket (included) to prevent thermal leakage.

  • Environmental Safety: Operates without CFCs or compressors, making it safe for indoor and portable use.

  • Life Expectancy: Peltier module rated for over 100,000 hours of operation under normal conditions.

  • Maximum Temperature Delta: Achieves a Tmax of over 60°C (difference between the hot and cold plates).

  • Insulation Efficiency: Performance is highly dependent on the insulation quality of the space being cooled; best for 5L to 10L enclosures.

  • Material Build: High-grade 6063 Aluminum alloy for heat sinks and impact-resistant ABS plastic for fan housings.

  • Mounting Structure: Rigid screw-and-nut assembly ensures uniform pressure across the Peltier chip, essential for efficient heat transfer.

  • Logic Compatibility: Can be controlled via an Arduino using a high-current Relay or MOSFET for automated temperature control.

  • Standardization: Designed for 12V DC systems, fitting perfectly with automotive and industrial power rails.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: Do not use a 9V battery. A standard 9V battery cannot provide the 5A to 6A current required. The Peltier will not cool and the battery will overheat. Use a 12V 10A DC Power Supply or a Car Battery.

  • 18650 Cell: You must use at least three 18650 cells in series (3S configuration). However, since the current draw is high, you need at least 3 strings in parallel (3S3P) with high-discharge cells (10A+ rating) and a 20A BMS.

  • IC & Capacitor Tip: For temperature control, use an STC-1000 Temperature Controller or an Arduino with a DS18B20 Sensor and a 30A Relay. Add a 4700uF 25V Capacitor across the 12V input to smooth out current spikes when the Peltier cycles on/off.

  • Related Products: We recommend pairing this with our 12V 10A SMPS Adapters, Digital Temperature Controllers, and Insulation Foam Sheets.

Package Includes

  • 1 x Thermoelectric Peltier Refrigeration Cooling System DIY Kit (Pre-assembled).
