Calculation Corner: Using Vendor Data to Estimate Thermoelectric Module Cooling Performance in An Application Environment
The application of thermoelectric devices to cool electronic components has been of interest to thermal engineers for many years. Thermoelectric (TE) cooling modules offer the potential to either reduce component operating temperatures at a given heat load, or allow higher component heat dissipation at a given temperature level. Readers who are unfamiliar with TE cooling … [Read more...]
