Functionality
Peltier-cooling-units consist of Peltier Modules, cooling unit and fan. The Peltier Module acts as heat pump assisted by a thermoelectric heat flow, which dissipates the heat from the cold-side to the warm-side of the module.
The thermal management on the warm-side is the determinating parameter for every application. The lower the temperature can be held on the warm side of the module, the cooler the cold side, the better the performance.
Therefore the heat has to be dissipated completely from the cold side to the warm side of the peltier module. The combination of cooling-body and fan ensures the best pumping performance on the cold-side and avoids over-heating of the peltier module.
The effective high-performance cooling units are based on a combination of static/dynamic principles. They are mounted on the peltier module by a Phase Change Materiall and ensure an optimal heat dissipation.
The current flow can be reversed by a pole reversal of the peltier modules. Warm-side and cold-side are exchanged and the cooling unit becomes an air-conditioner.
Advantages:
The advantages of peltier-cooling/heating-units:
- cooling and heating by means of peltier-technique
- non-movable parts (without wheel of the fan)
- no liquids or cooling liquids -> environment-friendly solution
- very low noise level
- compact size and low weight
- easy handling
- precise regulation of temperature
- usable in nearly every position
