TM 31-1.0-4.0 Thermoelectric Cooling Module
Specifications with Thot = 27°С
15 x 15 x 3.6
TM 31-1.0-4.0 is a general purpose single-stage thermoelectric module, with mid-range cooling capacity in the 15 x 15 mm footprint. This TEC has approximately 20% more cooling capacity than the 3-amp version of this module.
TM 31-1.0-4.0 may be used for spot cooling, heating and thermal stabilization and is employed in a wide range of applications including electro-optics, telecommunications, medical and military. A version for thermal cycling is available and recommended for airborne applications.
In electro-optic and photonic applications, TM 31-1.0-4.0 is commonly used to maintain a constant temperature in order to stabilize the wavelength of a diode, detector or sensor.

Performance Curves (click image for enlargement)
Thermoelectric module performance curves are graphical representations showing the relationships between power applied and net cooling for a specific TE module.
Performance curves are valuable tools for quickly determining if a TE module is a suitable COOLER for an application; learning what power is required for an appropriate module to reach the desired temperature and heat pumping capacity; and to provide the basic information necessary for proper assembly design.
Curves with Th = 27 °C indicate what to expect operating a well designed, fan cooled, assembly in ambient temperatures around 20 °C (70 °F) with an operational "hot-side" temperature or "Th" about 7 °C above ambient.
Curves with Th = 50 °C indicate performance expectations from assemblies with (relative) ambient temperatures in the 40-50 °C range. This includes assemblies with limited heat-sinking space yielding hot-side temperatures about 30 °C above ambient, marginally ventilated enclosures, outdoor, box-in-box, and other applications with warm temperatures around the hot-side of the TE assembly.
