2. Operating principle:
A TEC is able to transfer thermal power from one side of the module to the other by consuming
electrical power. The temperature drops on one side of the element, because of heat consumption
while it rises on the other side. For using this heatpump effect in a technical application, a setup
similar to figure 1 is to be built up.
This is the basic setup for any TEC-Application. The area to be temperature controlled must be
equipped with a temperature sensor. On the opposite side, the removed heat must be dissipated to
the ambient. The size of the heatsink and the quality of the thermal contact to the TEC has the
biggest influence on the performance of the whole system. The gap between the TEC and the
mounted parts (hot/cold side) must be as small as possible and only a very little amount auf
thermal conductive should be used to avoid air inclusions in the contact areas. For further
information such as mechanical loads for a durable setup visit our website www.quick-ohm.com.
