Terms of Use - Typically, the fins are oriented in a way to permit a natural convection air draft to flow upward through rectangular U-channels, or ducts, formed by the fins. If a processor is overheated and does not have a heat sink, the CPU can be damaged. An active heat sink uses an electronic device’s power supply to connect to a fan or a peltier device to actively divert heat away from the components by circulating air to cool the component or conduct heat away from it. W    A heat sink is a thermal conductive metal device designed to absorb and disperse heat away from a high temperature object such as a computer processor. Also, they create hazardous conditions for pilots and have been responsible for several disasters. G    These example sentences are selected automatically from various online news sources to reflect current usage of the word 'heat sink.' The heatsink is typically a metallic part which can be attached to a device releasing energy in the form of heat, with the aim of dissipating that heat to a surrounding fluid in order to prevent the device overheating. The picture is an example of a heat sink that has both active and passive cooling mechanisms. This is a coating between the device and the heat sink to improve thermal conduction. Heat sinks are devices that are used to enhance heat dissipation from hot surfaces to cooler ambient air. Figure 1. Delivered to your inbox! Overheating internal components can cause data loss, shortened computer lifespan, system crashes, lock-ups, random reboots and permanent damage. However, too much thermal paste will insulate the CPU instead of cooling it.Fans are used to cool the air and push hot air away from the computer and move cool air across the heat sink. F    Practical heat sinks for electronic devices must have a temperature higher than the surroundings to transfer … D    How does the Heat Sink Calculator Work? Looking for the abbreviation of Heat Sink? Most heat sinks have fins, thin slices of metal connected to the base of the heat sink, which help spread heat over a large area. A heat sink is a passive heat exchanger, and it is designed to have large surface area in contact with the surrounding (cooling) medium like air. The 6 Most Amazing AI Advances in Agriculture.

V    What made you want to look up heat sink? Heat sink definition is - a substance or device that absorbs or dissipates especially unwanted heat (as from a process or an electronic device). For layman readers that don’t know what diurnal variation is, it is the daily variation of temperature due to the variation of incoming solar radiation from rotation of the earth on its axis. 3. Britannica.com: Encyclopedia article about heat sink. Find more opposite words at wordhippo.com! E    A    A heat sink is a thermal conductive metal device designed to absorb and disperse heat away from a high temperature object such as a computer processor. Are These Autonomous Vehicles Ready for Our World? Temperatures should be kept between 90 and 110 degrees Fahrenheit, or 32 and 43 degrees Celsius. Usually heat sinks are outfitted with built-in fans to help keep both the CPU and the heat sink at an appropriate temperature. a substance or object that absorbs heat: At the back is a massive wall that acts as a heat sink - it cools the house in summer and in winter acts like a big radiator. Heat sinks are commonly used in all CPUs and are also used in refrigeration and air conditioning systems, GPUs and video card processors. The "d" shape causes airflow to back up and recirculate, spending more time in the heat sink, and removing more heat, before being channeled out by the "L" shape. An efficient Heat Sinks market to manage such high device volumes, diversity and geographies is the need of the time.Heat Sinks Market can be segmented into type, application, and geography. For example, 1. An antonym for heat sink is heat source. Consider a commonly encountered package, a flip chip BGA with a heat sink residing on top side of the device, Figure 1.
