Thermoelectric Cooling for Outdoor Kiosks

Introduction

Outdoor kiosks have grown in popularity in a wide variety of applications and sectors, including banking, entertainment, retail, showrooms, industrial and education. You see kiosks everywhere, from banks and airports, to theme parks and train stations. Being located outdoors, kiosks and the sensitive electronics they contain are subjected to extreme temperatures, from the cold of winter to the heat of summer. Ambient temperatures can exceed 40°C or below 10°C. Heat loads for the electronics themselves can range from 20 to more than 200 Watts.

Thermoelectric Cooling for CMOS Sensors

Introduction

For nearly 60 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.

Peltier Cooling for Machine Vision

Introduction

Machine vision is the replacement of human examination, assessment and decision-making with video hardware and software systems. The technology is often used for vision inspection, quality control, robotics, wire bonding and down-hole applications where machine vision systems obtain data from analyzing images of a specific process or activity. 

Peltier Cooling for Digital Light Processors

Introduction

Digital light processors employ a laser light source and millions of tiny mirrors to produce vibrant, high-resolution images for a wide variety of industries and applications. It is critical to maintain an optimum operating temperature during use to prevent degradation of the digital light processing technology. Active cooling solutions utilizing thermoelectric coolers can provide digital light processors thermal management in a wide range of high temperature applications. 

Thermoelectric Coolers for Reagent Storage

Introduction

Analytical chemists use reagents to detect the presence or absence of a substance, or to test if a specific reaction occurs. Laboratory and medical technicians use reagents to cause a chemical or biological reaction to measure or identify a target substance. Biotechnologists consider antibodies, model organisms, oligomers, and specific cell lines as reagents to identify and manipulate cell matter. These reagents, especially those used by the biotechnologist, have narrow operating temperature windows which require refrigeration or freezing.

Thermoelectric Cooler Assemblies for Reagent Storage

Introduction

Maintaining a temperature well below ambient, and monitoring this temperature carefully, are critical to extending the shelf life of reagents used for in vitro diagnostics. Most reagents require refrigeration and would spoil within hours at room temperatures. Reagents can degrade and become contaminated by microbial growth, which can affect test integrity results. Reagents can also be negatively impacted if they undergo too many freeze and thaw cycles. 

Recirculating Chillers for Industrial Lasers

Introduction

Industrial lasers are used for a wide range of applications including cutting, welding, micro-machining, additive manufacturing and drilling. No matter the application, industrial laser systems generate a significant amount of heat. There are several different types of industrial laser technologies, ultimately distinguished by the power density of the laser and its use. The commonality of every laser system is the need for advanced cooling of the power source and the laser optics.

Precise Temperature Control for Microscopes

Introduction

Electron microscopes are a powerful laboratory tool used to observe samples across many scientific disciplines. These advanced analytical instruments enable researchers to qualitatively and quantitatively analyze samples in fields like metallography, metrology, anthropology, zoology, epidemiology and more. Temperature control plays a dynamic role in ensuring the proper operation of electron microscopes.

Thermoelectric Cooling for Projection Lasers

Introduction

Laser projectors used for entertainment applications utilize laser modules to generate 4K-resolution images with a robust color palette and up to 75,000 lumens. While commercial laser projector systems quickly have evolved to be more energy-efficient, these systems still require up to 6kW to generate bright, high-resolution images. This is needed to project in cinemas and large venues at stadiums. Consequently, the high-power laser systems generate a significant amount of heat during operation.

Refrigeration Systems for Reagent Storage

Introduction

Reagents are essential for laboratory and medical testing. Reagent materials are used to detect the presence or absence of a substance, or to test if a specific reaction occurs. Thermal control is vital to preserve reagent materials, which can degrade over time when stored at improper temperatures. When they are kept at room temperature, reagents may become contaminated by microbial growth, which affects test integrity. Reagents can also be negatively affected at low temperatures if they undergo multiple freeze-thaw cycles.
