Cooling for Digital Light Processors

Digital Light Processors (DLP) make use of millions of micromirrors to produce vibrant, high-resolution images on a screen. The tiny micromirrors are placed on a semiconductor chip, known as a Digital Micromirror Device (DMD). This technology can be found in several industries ranging from Head-up displays and Smart headlights in the automotive market, Smartphones and other display and projection applications to advanced light control in 3D printing.

Thermoelectric Cooling for CMOS Sensors

Introduction

For nearly 50 years CCD (charge-coupled device) sensors and CMOS (complementary metal-oxide semiconductor) sensors have competed on cost and performance in a wide range of digital imaging applications. Peltier coolers (thermoelectric coolers) have cooled both technologies when the requirement demanded high-resolution images. Design engineers opted to use CCD’s for astrophotography, super-resolution microscopy, x-ray crystallography, and spectrophotometric assays. On the other hand, CMOS sensors made inexpensive digital photography a reality.

DA-014-12-02 Direct-to-Air

The DA-014-12-02 is a Direct-to-Air Thermoelectric Assembly (TEA) that uses impingement flow to transfer heat. It offers dependable, compact performance by cooling objects via conduction. Heat is absorbed through a cold plate and dissipated thru a high density heat exchanger equipped with an air ducted shroud and brand name fan. It has a maximum Qc of 12 Watts when ΔT = 0 and a maximum ΔT of 50 °C at Qc = 0.
