Development of microchannels and thermoelectrics for cooling in electronics

Tornado spectrum Systems是一家处于早期发展阶段的公司，开发创新的专有设备，为最终用户提供改进的工具，用于检测和表征生物、临床、工业和其他应用中的光谱现象（研究物质和辐射能量之间的相互作用）。该公司目前正在开发用于光学相干断层扫描（OCT）的设备，这是一种通过检测散射光波的信号来对各种样品进行成像的方法。为了在市场上处于领先地位，需要更高分辨率和更少失真的图像。提高质量的一种方法是降低探测器的温度，因为这将减少最终图像中的“噪声”。然而，目前探测器冷却的选择仅限于标准的大型解决方案。此次合作旨在利用滑铁卢大学的经验来开发先进的冷却解决方案，以扩大此类设备的可行应用空间。这个想法是在探测器上策略性地放置热电装置（微型冷却装置），它将进行现场冷却，并将它们与微通道耦合，微通道将作为背面的散热器。热电微层和类似的装置能够提供局部亚环境冷却，允许非常集中的主动冷却。此外，通过利用接触表面积和冷却剂的相变，微通道可以提供比标准散热器更好的散热。该项目的目标是在探测器上保持至少-10°C或更低的稳定温度。此外，所需冷却的区域相当小（微米量级）。这就是为什么微通道和微型热电器件是必不可少的。结果是一个增强的产品，扩大了这些被称为光谱仪的设备的可行市场。例如，医疗行业中更高质量的光谱数据可以彻底改变患者疾病的检测和早期诊断，并可能挽救生命。

Tornado Spectral Systems is an early-stage company that develops innovative, proprietary devices that provide end users with improved tools to detect and characterize spectral phenomena (studying interactions between matter and radiated energy) in biological, clinical, industrial, and other applications. The company is currently developing devices used in Optical Coherence Tomography (OCT), a method used to image various samples by detecting signals from scattered waves of light. In order to be a leader in the marketplace, higher resolution images with fewer distortions are desired. One way to improve quality is to lower the temperature at the detector as it will reduce "noise" in the final image. However, current options for detector cooling are limited to standard large solutions. This collaboration aims to leverage experience from the University of Waterloo to develop advanced cooling solutions to expand the viable application space for such devices. The idea is to use strategically placed thermoelectric devices (miniature cooling devices) on the detector that will carry out on-the-spot cooling and couple them with microchannels that will act as heat sinks on the backside. Thermoelectric micropeltiers and similar devices are capable of providing localized sub-ambient cooling allowing for very focused active cooling. Also, microchannels can provide superior heat dissipation over standard heat sinks by leveraging both contact surface area and phase change of the coolant. The project aim will be to maintain a stable temperature at the detector of at least -10°C or cooler. In addition, the region of desired cooling is rather small (on the order of microns). This is why microchannels and miniature thermoelectric devices are essential. The result is an enhanced product that expands the viable market for these devices known as spectrometers. Higher quality spectroscopic data in the medical industry, for example, can revolutionize detection and early diagnosis of illnesses in patients and potentially save lives.
