It’s an ideal choice for electronics and Power Electronics applications because of its passive operation, di-electric working fluid options, and high performance. The “loop” aspect makes this possible by designing a discrete vapor line to the heat sink, condensing within the heatsink, and liquid returning down a separate fluid line.Ī loop thermosyphon is a scalable technology, with products built from less than 100W to upward of 75,000W. A Loop Thermosyphon can move larger amounts of heat compared to a similar-sized heat pipe or thermosyphon because there is no counterflow (liquid and vapor moving in opposing directions). The system takes advantage of the latent heat of the fluid which allows for such high heat transfer rates. The expansion of this fluid as it changes phase from liquid to vapor creates a stirring motion that increases convection and subsequently, heat transfer efficiency. The principle operation is similar to a heat pipe or thermosyphon where heat generated by components causes liquid within the attached cold plates to evaporate. ACT systems are fielded in a variety of industries including medical, energy/utility, automation and HVAC systems.

LTS are routinely found in Power Electronics applications where customers mount IGBTs and other high-power density devices directly to an evaporator plate and have the ability to remotely locate the condenser or heat sink above the components. The best thing to do, is to set everything up and try moving things around until you don’t have feedback anymore.A Loop Thermosyphon (LTS) is an ideal solution for any system that can leverage gravity assist fluid return. Remember it takes a little bit of time to understand the concept of feedback and in the beginning it will occur anytime you put together a mic, amp and speakers. These suggestions above are some quick and simple ideas to help you when setting up a microphone and speakers. Instead of using speaker monitors try using a headset or in-ear monitors. Place the speakers at the front of the stage rather than at the back. Lower the volume of the speakers, so the mic doesn't pick it up. Turn off the microphone when you’re not using it.Įqualizing (or EQing) the mix or lower the frequencies which are causing the feedback. Speaking close to the microphone can help so that it doesn’t pick up other sounds. Here are some suggestions for controlling this pesky feedback: Maybe you’re setting up a podium for a speech in front of a crowd or perhaps setting microphones for a musical performance.

This is a sure-fire way of not getting feedback. Well for starters, you want to not point the microphone toward the speakers as much as possible. The distance between the mic and the speakers has a lot to do with the frequency of the squealing, because that distance controls how quickly the sound can loop through the system. It happens so quickly that it creates its own frequency, which we hear as a squealing sound. This loop is called feedback or a feedback loop. The sound of the tap goes into the mic, through the amplifier and comes out the speaker which then re-enters the microphone then goes through the amplifier and comes out the speaker which then re-enters the mic then goes though the amplifier… you get the idea. Imagine, for example, that you place the microphone in front of the speaker as shown above.
