Heat Exchangers for Today’s Immersion Cooling Systems
IT advancements and higher power and performance requirements have increased the amount of heat generated in data centers. To lower operating costs, immersion cooling utilizing heat exchangers has gained in popularity. Providing precise temperature control and bulk heat removal, this is also proved to be a more efficient cooling solution.
Heat Exchangers for Today’s Immersion Cooling Systems
Introduction
Increased server rack density has been greatly impacted by advancements in artificial intelligence, Internet of Things (IoT), machine learning, blockchain, cryptocurrency and the demand for increased computing power and performance requirements. This has contributed to an increase in the amount of heat generated in data centers. Traditional methods of air cooling have fallen short of meeting the thermal management requirements for the latest generation of servers, central processing units (CPUs) and graphics processing units (GPUs).

莱尔德热系统PowerCycling PCX细长型热电冷却器可加速 PCR 测试
PowerCycling PCX 细长型系列可提供牢固的模块化结构，在热循环应用中具有高可靠性。
2022 年 2 月 7 日 — 用于实时 PCR应用的热循环设备通过利用热电技术来精确管理温度设置和升温速率，从而实现 DNA 片段的扩增。为了提高 PCR 设备的温度控制精度，莱尔德热系统（Laird Thermal Systems）开发了一个细长系列 PowerCycling PCX 热电冷却器，该系列采用专有的工艺和独特的模块化结构，能够为 PCR 应用提供高可靠性和最小的温度梯度，从而实现更高测试产量和更快速的测试结果。
PCR 需要数量巨大的热循环来产生数百万条用于医学诊断的 DNA 链，其中每个热循环由三个步骤组成：第一步在 95℃高温下分离 DNA 链，第二步冷却至 50～65℃之间的熔解温度，此时生物标志物将与 DNA 结合，第三步将温度升高至 72℃以对 DNA 拷贝进行测序。热电冷却器安装在 PCR孔井下方，可将这些温度设定点精确控制在 ±0.5℃以内。
