AI, E-commerce, high-performance computing, 3D graphics, and IoT applications demand faster and more complex computing. The rapidly growing cloud services business is creating a need for efficient use of data center space, driving demand for more computing capacity per unit area in a data center. The thermal design power of CPUs and GPUs has increased from about 100-150 W a few years ago to over 600 W now. Many liquid cooling and immersion cooling technologies have been proposed with a significant amount of attention and investment. However, they remain on the fringes while the heat pipe based systems are still the mainstay. There is a need to push the envelope of this passive and versatile technology further.
5G is s a revolutionary technology that will eliminate bandwidth, performance, and latency limitations on connectivity worldwide; thus enabling fundamentally new applications and business models. Its low latency connectivity allows new applications in the mobile, eHealth, autonomous vehicles, smart cities/homes, and IoT sectors. Consistent and reliable connectivity is essential through proper infrastructure, which includes devices such as environmentally protected 5G RRU/RRHs and other transmitters. Millimeter wave architecture results in significantly higher heat load, yet it is imperative that the fanless architecture is still utilized. There is a need to provide significantly higher passive cooling capability with extremely high reliability.
Most workstations and high-performance computing need an increasingly faster CPU and GPU for various computational tasks. Today, this market is served by heat pipe heat sinks or liquid cooling. Similarly, gaming enthusiasts require high performance and reliability from their hardware to drive an immersive gaming experience. Due to its high thermal performance, liquid cooling has been the go to technology so far. However, there is significant frustration with its high cost, low reliability, and complgo-toex integration. To enable CPU overclocking and optimal GPU performance, there is a need for a passive technology that can meet the performance and remote cooling capability afforded by liquid cooling.
Li-ion batteries are widely gaining momentum, not only for the EV market, but also as an alternative clean energy storage technology to solar or wind energy. High temperature operation of these batteries is detrimental to their efficiency as well as lifecycle. Temperature rise is caused due to battery self heating during the charging and discharging process. Although air cooling is routinely implemented, the more effective way to control rises in temperature is with liquid cooling, an effective thermal management strategy that extends battery pack service life. Deeia’s Loop Thermosyphon has the potential to replace the liquid cooling systems in EVs and stationary battery packs to provide unsurpassed thermal management of these batteries.
