遠心分離機の冷却
遠心分離機は、遠心力を使って混合液を分離する実験室用の装置です。液体を分離するため、遠心分離機は試料を高速で回転させると、その結果、重い成分は中心から最も遠い所へ飛ばされ、軽い成分は中心軸の近くにやってきます。遠心分離デバイスは、フードプロセッシングや細胞の医療研究、遺伝子と蛋白質の分析で広く使われています。実験室や医療用の遠心分離機を設計するときは、設計上のいくつかの問題を考慮しなければなりません。
生きた細胞や薄い組織、蛋白質のように温度に敏感な試料が多くあります。これらは、適切な反応や生存能力を保証するため、正確な温度で保管されテストされなければなりません。さらに床面積や騒音、振動、消費電力の削減など、設計上の問題も加わります。加えて、多くの政府が、コンプレッサベースのシステムの中心となる、従来の自然な冷却剤の使用を制限しています。

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.
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.
