Peltier modules or thermoelectric coolers (TEC) are basically thermoelectric heat pumps. It means that by supplying electrical energy, heat can be transported against its natural gradient, from one side of the peltier module where heat is absorbed to the other side, where heat is released. Thus, it is possible to use these peltier modules for heating or cooling applications. This behaviour is defined by the direction of the current. Theoretically, the temperature difference can go up to 73K for a simple element and up to over 100K for multi-level elements. In general, peltier modules are used wherever cooling with a small temperature difference, precise control and dynamic behaviour is necessary. The application of Peltier modules are very diverse, starting from complex analysis technology in the field of medicine to light-sensitive CCD sensors and mobile cooling applications.

Meaning of the Quick-Ohm article number for Peltier modules: Example: QC-127-1.4-15.0MX

QC: Quick-Cool - 127: Number of installed semiconductor pairs - 1.4: Edge length of the semiconductor blocks (cuboids) in mm - 15.0: ≈Imax in A - M: Quality index: [A = standard (approx. 20,000 cycles, Tmax = 100 ° C), M = Premium (approx. 800,000 cycles, Tmax = 200 ° C), MM = Superior (approx. 2,000,000 cycles, Tmax = 200 ° C)] - X: Sealing (blank = none, S = silicone, X = epoxy resin)
