A Simple Method to Estimate the Physical Characteristics of a Thermoelectric Cooler from Vendor Datasheets
Introduction A thermoelectric cooler (TEC) is a solid-state refrigerator that operates on the Peltier effect. The absence of moving parts, compact size, precise temperature control ability and reliability all combine to make the TEC a unique refrigerator. TECs find application [1, 2] in many fields from simple food and beverage coolers for an afternoon picnic to extremely … [Read more...]
Effect Of Improved Thermoelectric Zts On Electronic Module Coolability
In recent years there has been a growing interest in the application of thermoelectrics to electronics cooling. Attention has been focused on thermoelectric cooling both as a possible means to enhance module cooling and to address the chip hot spot problem. Effort has been directed towards the development of new bulk materials and thin film micro-coolers. The usefulness of … [Read more...]
Thermal Challenges In LED Cooling
Introduction During the last ten years, developments in LED semiconductors have led to an important change in LED applications from that of luminous indicator to that of illuminator. With LEDs now advancing into several lighting fields, LEDs have become one of the standard methods of producing light, joining more traditional sources such as incandescent, fluorescent and … [Read more...]
Advances In High-Performance Cooling For Electronics
Introduction The need for new cooling techniques is driven by the continuing increases in power dissipation of electronic parts and systems. In many instances standard techniques cannot achieve the required cooling performance due to physical limitations in heat transfer capabilities. These limitations are principally related to the limited thermal conductivity of air for … [Read more...]
