Spot Cooling for Industrial Lasers & Optics

Introduction

With an increasing demand for advanced industrial manufacturing, laser systems have become the most important fabrication tool. While high powered lasers such as CO2 lasers are used for coarse cuts of metals, ultrafast lasers are used for fine cuts and polishing of semiconductor materials. Fiber lasers have the versatility to do both. In today’s consumer electronics, electrification of vehicles and green energy are driving the need for advanced laser machining and additive machining of complex materials.

Corrosion Prevention in Cooling Loops

Introduction

Corrosion in liquid cooling loops is caused by chemical, electro-chemical, or abrasive action by the heat transfer fluid on the wetted surfaces. Chemical product layers formed by corrosion can inhibit suitable heat transfer between the liquid and wetted metal surfaces. The corrosive products can introduce debris into the fluid system affecting fluid flow, clogging up filters and tight restrictions, or even damaging pump components. In extreme conditions, leaks can form if enough material is removed from the fluid containment.

Liquid to Liquid Ambient Cooling Systems for Semiconductor Tools

Introduction

Cooling and temperature control systems are used throughout semiconductor fabrication facilities. In fabrication facilities both large and small, hundreds to thousands of cooling systems are installed and operate continuously. The processes employed are usually setup as copy-exact, which means the process systems are developed and transferred from the OEM of the process tool. These critical production tools used in semiconductor fabrication facilities are required to be reliable and easy to service to deliver minimum downtime.

Next Generation Thermoelectrics Designed for Real-Time PCR

Introductions

Polymerase chain reaction (PCR) is a technique used in molecular diagnostics to amplify sequencing of DNA. Also referred to as molecular photocopying, the DNA produced by PCR is vital to many laboratory and clinical procedures. PCR testing has been instrumental in the diagnosis of SARS-CoV-2, better known as COVID-19. Not only do PCR tests detect the presence of a virus during testing but it will also detect fragments of a virus even after the patient is no longer infected.

Thermal Management for Semiconductor Metrology Equipment

Introduction

The history of thin film semiconductor manufacturing has been one of constant process improvement. This constant process improvement was necessary in order to establish cost effective high yielding production lines as they struggled to keep pace with Moore’s law. All of this has been made possible through the integration of automated metrology systems with statistical process control. 

Spindle Screw Pump Technology for Medical Cooling

Introduction

Spindle screw pumps feature a simple construction that offers high reliability, performance and efficiency for liquid cooling systems. Comprised of a single rotor element that is powered, while two others are idle, spindle screw pumps move fluid axially without turbulence, eliminating foaming that would otherwise occur in viscous fluids. The idle rotors are rotated by liquid pressure, essentially generating a fluid bearing, or hydrodynamic film, that provides radial support similar to journal bearings. 

Bi-directional Microcontrollers Monitor and Protect Medical Equipment

Introduction

Product innovations in medical diagnostic equipment and analytical instrumentation are primarily aimed at improving testing reliability to ensure repeatable results, decreasing equipment size, and reducing both equipment and procedural costs. Satisfying conflicting requirements of increased performance with lower power consumption and quieter operation in a compact design is a continuing challenge facing design engineers.

Compact Temperature Control for Medical Diagnostic and Analytical Instrumentation

Introduction

The trend to miniaturize medical diagnostic and analytical instrumentation to free up precious lab space has led engineers to pack more functionality into a tighter space constraint. This increases the heat flux by packing electronics in a smaller footprint and has led to thermal challenges. Waste heat must be efficiently managed to meet conflicting requirements of increased performance with reduced power consumption and quieter operation all in a compact design.

Thermal Management Solutions for Beverage Cooling

Overview

Refrigeration units are vital to the food and beverage industry to ensure proper storage temperatures and to maintain health and safety regulations. Refrigeration and cooling methods continually advance to simplify beverage transportation and beverage dispensing. From small consumer appliances used to refrigerate milk, coffee, beer, juice, soda and wine, to large mobile carts that transport food from a kitchen to a catering point, refrigeration ensures beverages are consumed at appropriate safe temperatures.
