PELTIER COOLERS
Daniel L. Thomas, founder of Novel Concepts, has been designing custom Peltier (solid state thermoelectric) modules and Peltier Coolers since 1982, with heat pump capacities ranging from a few watts to thousands of watts. An example of the broad variety of Peltier cooler related technologies we have developed include:
- low stress heat sinks for large Peltier cooler arrays
- notebook, desktop, and handheld microprocessor Peltier coolers
- wearable thermal Peltier cooler signaling devices
- programmable Peltier laser chillers for wafer fabrication
- Peltier cooler computer enclosures for the Alaska pipeline
- solid state temperature sensors for data acquisition
Using proprietary software developed by Novel Concepts called PumpDes, all Peltier cooler performance parameters can by independently optimized. In addition, PumpDes can be linked to SinkDes (proprietary heat sink shape optimization software), for maximum heat pump performance.
We routinely develop forced convection (air-to-air) Peltier Coolers with volumetric efficiencies as high as 0.25 W/cc.
By using IsoFilm heat spreaders to effectively transfer heat to and from the Peltier module, Novel Concepts has been able to design higher power density Peltier coolers without sacrificing their maximum temperature differentials. Since the manufacturing cost of a Peltier module is highly dependent on its size and not its heat pumping capacity, higher power density designs have higher performance versus cost ratios.
