🔷Operation Principle
Based on the Peltier effect, when DC current flows through the thermoelectric cooling element module, one side of the peltier cooler absorbs heat and turns cold, while the opposite side releases heat and turns hot. You can switch cooling and heating function by reversing the DC current direction. Unlike compressor refrigeration, this thermoelectric cooling element realizes heat transfer without any refrigerant.
🔷FAQ
Q1: What is the working voltage for TEC1‑12704 thermoelectric cooling element?
A: Its rated working voltage is 12V, the maximum voltage can not exceed 15.4V. Excessive voltage will cause permanent burn‑out of the peltier module.
Q2: Can you provide custom thermoelectric cooling element cooling plate?
A: Yes, we support custom thermoelectric cooling element cooling plate, custom wire length and surface treatment solution. OEM service is available.
Q3: Are you thermoelectric cooling element supplier that supports bulk order?
A: Yes. We supply wholesale thermoelectric cooling element for distributors, system integrators and OEM manufacturers. Large quantity with competitive price.
Q4: Can this 40*40mm thermoelectric cooling element be used for laser cooling?
A: Sure, this high‑efficiency peltier cooler is a very common option for small laser module temperature control.
