Introduction

Air conditioners utilizing thermoelectric coolers are often considered as an alternative to conventional vapor-compression systems for enclosure cooling. Because a thermoelectric cooler is compact, robust, and completely solid-state, the inherent reliability of such a system is attractive to engineers and end-users alike. However, there is an inherent reluctance to choose a thermoelectric-based system due to preconceptions about energy efficiency or lack of experience with thermoelectrics.

Introduction

Engineers of all disciplines more frequently need a Thermal Wizard, someone who can solve their heat dissipation or critical thermal management problems. If you need a Thermal Wizard or you are that Thermal Wizard that coworkers count on, then you are familiar with the more common issues associated with solving unanticipated or sudden thermal management problems.

简介

循环冷水机是许多现代实验室的重要组成部分，尤其是在分析、制药、化学和生物技术等行业更为明显。它们通过有效地制冷和循环液体，在保持工艺过程或系统的精确温度范围方面发挥着至关重要作用。这样能够确保各种设备和工艺过程的正确功能和准确性，例如激光器、蒸馏塔、试验室和分析仪器等。近年来，在不断发展的法规和行业标准推动下，实验室设计越来越重视可持续性和能源效率，这一趋势导致了“绿色实验室”的快速发展，目的是最大限度地降低能源消耗并减少对环境的影响。绿色实验室若要实现这些目标，一种有效方法是使用节能型循环冷水机，并确保这些冷水机使用对环境安全的制冷剂。

应用背景

实验室设备中的很大一部分需要对热敏电子设备、电子元器件以及实验室设备测试室进行精确温控。化学反应过程中会释放或吸收热量，需要精确的温度控制以保持化学反应稳定。实验室设备小型化的趋势也会增加热流密度，从而加剧热管理挑战。当发热电子设备被封装在较小的外壳中时，自然气流和散热的物理空间较小，但废热必须有效散发出去，以确保实验室设备的正常性能和测试室中化学反应的最佳控制。

Introduction

Particle accelerators, such as linear accelerator (LINAC) and cyclotron systems, increase the kinetic energy of particles for use in a variety of applications, ranging from scientific studies on particle physics to radiation therapy for cancer patients. Particle accelerators, like most sensitive medical and laboratory equipment, are negatively affected by thermal variations, specifically an increase in heat. Temperature control of vital particle accelerator system components is critical for operational integrity, performance accuracy and system reliability.
