4 How it works
GB
4 How it works
The Rittal Thermoelectric Cooler uses the Peltier effect for cooling. This effect is based on the principle
that an electric direct-current flowing through a circuit consisting of two different metals causes the
cooling of one contact point and the heating of the
other contact points. An appropriate layout for the
cooling production is designated as Peltier element.
When the Peltier effect is used for enclosure climate
control, an air flow is fed over the upper and lower
connection point. The heat energy is released or
accepted from the air flow to the Peltier element.
The air flow that releases the heat energy to the element is introduced as cooling air flow in the enclosure or the operating housing. After
the heating of the
cooling air flow by the active installed equipemt
, it is
returned to the cooling unit and fed for renewed cooling over the “cold” side of the Peltier element. This
produces an air circulation that causes the cooling of
the enclosure or the operating housing.
The air flow that accepts the heat energy from the
“warm” side of the Peltier element is released as
warm air flow to the external air circuit of the cooling
unit. This means the heat produced by the components in the enclosure is dissipated to the ambient air
surrounding the cooling unit.
