13.56MHz MIFARE Classic 1K RFID Contactless Smart Card for Access Control and Identity Management

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.
