Thermoelectric cooling
Thermoelectricity refers to the mutual influence of temperature and electricity. The Peltier effect refers to the phenomenon whereby a temperature difference is generated by an electrical current, and was discovered by Jean Peltier in the 19th century.
Unlike refrigerators, Peltier elements do not require a compressor or refrigerant, are low-noise, and have no moving parts. For this reason, they are particularly well-suited for cooling lasers or microprocessors.
In the past, the low level of efficiency of Peltier elements posed a problem for their industrial use in cooling units. Based on the following assumptions, Rittal is working towards its vision of a nano-coated, thermoelectric cooling unit for enclosure climate control:
Nano-coated cooling
- Optimised thermal transfer A,B,C
- Efficiency increased by a factor of 2-3 compared with Peltier
- Space optimisation -> maximum output
- Side panels: Enclosure cooling up to 2000 W
