pengenalan
This manual provides instructions for the Walfront Peltier Cooler Semiconductor Refrigeration Cooling System DIY Kit. This system utilizes advanced semiconductor technologies for solid-state cooling, suitable for various small-space cooling applications.
The refrigeration effect is influenced by factors such as cooling space size, ambient temperature, heat insulation, and sealing capabilities. This kit is designed for easy installation and offers efficient cooling with low noise.
Maklumat Keselamatan
- Ensure all electrical connections are secure and correctly polarized before applying power.
- Use a stable 12V 6A (or higher amperage) power supply. Incorrect voltage or current can damage the unit.
- Avoid touching the cooling and heating surfaces during operation, as temperatures can be extreme.
- Proper heat dissipation on the hot side is crucial for optimal performance and longevity.
- Keep the unit away from water or excessive moisture unless specifically designed for such environments.
Amaran: This is a DIY kit and requires basic electrical and assembly knowledge. Improper installation can lead to damage or injury.

Sambungan Bekalan Kuasa
A stable 12V 10A power supply is recommended for optimal performance. Ensure correct polarity when connecting.
Image: Wiring diagram for connecting the Peltier cooler to a 12V 10A power supply and an optional thermostat. The positive terminal of the power supply connects to the first port, negative to the second. The positive pole of the refrigerator connects to the first port, and the negative end to the fourth end. The middle line loop connects to the second and third ports.
DIY Small Refrigerator Installation Steps
This unit can be integrated into a small insulated enclosure to create a mini-refrigerator.
Image: Visual guide for integrating the Peltier cooler into a small insulated box. Steps include drawing a line on the box, cutting holes, inserting the isolation board, and connecting the cold end of the refrigerator with the isolation plate.
- Draw a good line on the box body according to the size of the protruding part of the isolation board.
- Cut holes along the drawn line with a box cutter.
- Put the protruding part of the isolation board on the inside of the box.
- Connect the cold end of the refrigerator with the hole of the isolation plate. Ensure the cold end extends as far as possible into the cooling space.
Arahan Operasi
Once properly installed and connected to a 12V power supply, the unit will begin to cool.
- The cooling effect is immediate on the cold side, while the hot side will dissipate heat.
- For optimal performance, ensure adequate ventilation around the hot side heatsink to allow for efficient heat rejection.
- Sistem ini direka untuk operasi berterusan.
Pertimbangan Prestasi
Image: A test showing temperature reduction in a 300x200x250mm insulated box. Initial temperature 25.1°C. After 3 minutes, 20.6°C. After 10 minutes, 15.2°C. After 40 minutes, 12.5°C. Notes indicate that frosting may occur on the cold end over time, and fans may freeze, suggesting slight adjustment of screws on the cold end fan if this occurs.
The cooling performance depends on the insulation of the cooling space. Good insulation, such as 1-inch foam or tin foil paper, significantly improves efficiency.
Over extended periods, the cold end may experience frosting. If the fan on the cold end freezes, slightly loosen its mounting screws to allow for proper operation.
Penyelenggaraan
- Regularly inspect the fans for dust accumulation. Clean with compressed air or a soft brush to maintain airflow.
- Pastikan semua sambungan elektrik kekal kukuh.
- Check for any signs of damage to the heatsinks or fans.
- If the unit is used in a humid environment, periodically check for excessive condensation or ice buildup on the cold side.
Menyelesaikan masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Tiada penyejukan | No power, incorrect wiring, faulty power supply | Check power connections, ensure 12V supply, verify polarity. |
| Penyejukan yang tidak mencukupi | Poor insulation, inadequate heat dissipation, fan obstruction | Improve insulation of the cooling space. Ensure hot side fan is clear and operating. Clean heatsinks. |
| Cold side fan freezing | Excessive frosting | Slightly loosen the screws on the cold end fan to prevent obstruction. |
| Unit terlalu panas | Blocked hot side fan, insufficient ventilation | Clear any obstructions from the hot side fan. Ensure ample space for airflow. |
