1. Introduktion
The uxcell TEC1-12705 is a thermoelectric cooler, also known as a Peltier module, designed for various heating and cooling applications. This device utilizes the Peltier effect to create a temperature difference across its two ceramic surfaces when a direct current is applied. It is composed of semiconductor materials sandwiched between ceramic plates and operates without any moving parts, offering reliable performance for applications ranging from CPU cooling to portable refrigeration.
2. Sikkerhedsoplysninger
Vigtige sikkerhedsforanstaltninger:
- Heat Sink Requirement: The TEC1-12705 module must always be used in conjunction with an appropriate heat sink on its hot side. Failure to do so will result in immediate overheating and permanent damage to the module.
- Termisk fedt: Always apply a thin, even layer of high-quality thermal grease between the TEC module and both the heat sink and the object being cooled/heated to ensure efficient heat transfer.
- Strømforsyning: Use a stable 12V DC power supply capable of providing at least 5A. Exceeding the maximum voltage or current can damage the module.
- Polaritet: Incorrect polarity will reverse the heating/cooling effect. Ensure correct wiring for the desired operation.
- Temperaturområde: Operate the module within its specified temperature range of -55°C to 83°C.

5. Opsætning og installation
5.1 Generelle retningslinjer for installation
- Forberedelse af overfladen: Ensure that both surfaces (the TEC module and the heat sink/object to be cooled) are clean, flat, and free from dust or debris.
- Thermal Grease Application: Apply a thin, even layer of thermal grease to both sides of the TEC module that will be in contact with other surfaces. This maximizes thermal conductivity.
- Heat Sink Attachment: Securely attach a suitable heat sink to the designated 'hot' side of the TEC module. The hot side is the one opposite the side that cools when the red wire is positive and black is negative. Ensure firm and even pressure across the entire surface.
- Montering: The module can be mounted using appropriate fasteners or clamps, ensuring not to over-tighten and damage the ceramic plates.
5.2 Wiring and Polarity
The TEC1-12705 module has two wires: one red and one black. The polarity of the power supply determines whether the module cools or heats a specific side.
- Køletilstand: To achieve cooling on the side marked with the model number (TEC1-12705), connect the red wire to the positive (+) terminal of your 12V DC power supply and the black wire to the negative (-) terminal. The opposite side will become hot and requires a heat sink.
- Opvarmningstilstand: To achieve heating on the side marked with the model number, reverse the polarity: connect the red wire to the negative (-) terminal og den black wire to the positive (+) terminal. The opposite side will become cold.
Billede: This image shows a close-up of the red and black insulated wires extending from the thermoelectric cooler module. The red wire is typically connected to the positive terminal and the black wire to the negative terminal for standard cooling operation on the labeled side.
6. Betjeningsvejledning
Once properly installed with a heat sink and connected to a 12V DC power supply, the TEC1-12705 module will begin to create a temperature differential.
- Køling: With the red wire connected to positive and black to negative, the side of the module with the model number printed on it will become cold, while the opposite side will become hot.
- Opvarmning: By reversing the polarity (red to negative, black to positive), the side with the model number will become hot, and the opposite side will become cold.
The module can achieve a maximum temperature difference (ΔTmax) of up to 61°C under ideal conditions (Qc=0, no heat load). The actual temperature difference will vary depending on the heat load and the efficiency of the heat sink used.
7. Vedligeholdelse
The TEC1-12705 module is a solid-state device with no moving parts, requiring minimal maintenance.
- Renhed: Periodically inspect the module and heat sink for dust accumulation. Dust can impede airflow and reduce heat sink efficiency. Clean gently with compressed air or a soft brush.
- Thermal Grease Integrity: Over time, thermal grease can dry out or degrade. If you notice a significant drop in performance, consider reapplying fresh thermal grease.
- Tilslutningskontrol: Sørg for, at alle elektriske forbindelser forbliver sikre og fri for korrosion.
8. Fejlfinding
If the uxcell TEC1-12705 module is not performing as expected, consider the following:
- No Cooling/Heating:
- Verify the 12V DC power supply is functioning and providing sufficient current (at least 5A).
- Check wiring for correct polarity.
- Sørg for, at forbindelserne er sikre.
- Utilstrækkelig køling/opvarmning:
- Confirm that a proper heat sink is securely attached to the hot side of the module.
- Check for proper application and integrity of thermal grease between all contact surfaces.
- Ensure adequate airflow around the heat sink for efficient heat dissipation.
- Verify the ambient temperature is within the operating range.
- Overophedning af modul:
- This is almost always due to insufficient heat dissipation on the hot side. Ensure the heat sink is adequately sized for the heat load and has good thermal contact.
- Check for proper thermal grease application.
- Ensure the power supply is not exceeding 12V or 5A, which could lead to excessive heat generation.
