heat sink definition computer

Disconnect the fan The heat sink for this computer's processor is not visible until this duct is removed from the computer. Heatsinks leverage a thermal conductor to move the heat into fins, which have larger surface areas and thus disperse the heat throughout the computer. Find out inside PCMag's comprehensive tech and computer-related encyclopedia. A heat sink is an object that transfers thermal energy from a higher temperature to a lower temperature fluid medium. Of the three resistances, we can really only control the last two because the component’s thermal resistance is defined by the manufacturer. The heat transfer efficiencies have been measured for a wide range of heat sink configurations, and their ranges are listed in Table 4. A heat sink is a metallic device that sits directly on the CPU, drawing heat away from the chip into its cooler, aluminum, fin-like structure. and fan to cool them down. heat sinks Definitions. Thermal paste (also called thermal compound, thermal grease, thermal interface material (TIM), thermal gel, heat paste, heat sink compound, heat sink paste or CPU grease) is a thermally conductive (but usually electrically insulating) chemical compound, which is commonly used as an interface between heat sinks and heat sources such as high-power semiconductor devices. The fluid medium is frequently air, but can also be water or in the case of heat exchangers, refrigerants and oil. where, m is the mass flow rate through the heat sink, c is the heat capacity of the fluid, and. Smartphones or tablets do not have space for heat sinks or fans. Let’s take a look at 6 common heat sink types. ‘Every computer contains a device known as a heat sink.’ ‘The expanding universe is quite an effective heat sink.’ ‘Judging by the small size of the heat sink and fan … Some also require a fan. Actually, What exactly is a heat? A heat sink without a fan is called a passive heat sink; a heat sink with a fan is called an active heat sink. Heat sink Definition from Computer & Internet Dictionaries & Glossaries. HSF: Stands for "Heat Sink and Fan." Heat sink is an electronic component or a device of an electronic circuit which disperses heat from other components (mainly from the power transistors) of a circuit into the surrounding medium and cools them for improving their performance, reliability and also avoids the premature failure of the components. heat sink - a metal conductor specially designed to conduct (and radiate) heat. translation and definition "heat sinks", Dictionary English-English online. Plural form of heat sink. In doing so, the Heat Sink on a Chip This type of heat sink is glued to the top of the chip, typically a CPU chip, which generates considerable heat. Heat transfer from the heat sink consists of radiation and convection from both the intra-fin passages and ... such as computer chips, electronics, and telecommunication boxes. Otherwise, it can have a very negative effect on its performance and in extreme cases, the system will shut down if the heat is excessive. conductor - a device designed to transmit electricity, heat, etc. 1. Heat sink definition is - a substance or device that absorbs or dissipates especially unwanted heat (as from a process or an electronic device). For yet another, it is not 3/4 covered by a massive liquid heat-sink that convectively carries heat across its surface. This can happen if the CPU is running at full capacity for an extended period of time or if the air surrounding the computer is simply too hot. Figure 1: Micro blower-heat sink system for portable computer. The correct definition of heat says that it is the total kinetic energy of all atoms or molecules of a substance. When a computer is in use, electrical activity within the CPU and chipset generates considerable heat, which if not dissipated, will damage or even melt the chips, making them inoperable. Both a heat sink and a radiator require airflow and, therefore, both have fans built in. sink - (technology) a process that acts to absorb or remove energy or a substance from a system; "the ocean is a sink for carbon dioxide" A heat sink is a metal plate that is specially designed to conduct and radiate heat away from an electrical component. It's amazingly detailed -- separate gingerbread RAM, heat-sink, etc, all lovingly assembled on a gingerbreadboard. Learn more. A heat sink is a device that allows the transfer of heat away from the heat source. Heat sink definition, any environment or medium that absorbs heat. For this computer, the duct system can be removed by pressing in on the clips and pulling the duct away from the processor. All modern CPUs require a heat sink. Video cards therefore need to employ heat sinks, which consist of metal strips to distribute the heat evenly and dissipate the heat into the surrounding air. After the duct is removed, the computer processor and the heat sink should be visible. After passing the heat sink, the liquid was cooled down in the external heat exchanger (4) and collected in the reservoir (5). There are a number of different ways to make heat sinks. Some also require a fan. The main advantages of natural convection are high Figure 2: Axial fan-heat sinks systems for portable computer. Internet Dictionaries. In most of computer processor, a fan is attached just above the heat sink. Global Hot Air « Lean Left. en.wiktionary.org. This heat needs to be removed from the component Heat Sink. Heat sink design goals may vary, but in this report, optimization of the vertical heat sink is the main objective. Passive Heat Sink. When the heat sink utilizes fan (HSF) it is active heat sink. See more. This utilizes power for cooling process. Boing Boing: December 11, 2005 - … Internet Glossary. The metal heat sink ensures good heat dispersal and allows a low hot-spot temperature. Active heat sinks are used in liquid cooling system. The majority of heat … For the cooling purpose,it incorporates a fan or cooling device. Selecting the Heat Sink and Compound. The heat sink has a thermal conductor that carries heat away from the CPU into fins that provide a large surface area for the heat to dissipate throughout the rest of the computer, thus cooling both the heat sink and processor. Use a search engine. It can be in the form of a paste or jelly or a simplealuminum structure which is attached to the heat source. The mentioned heat sink is part of an experimental setup presented in Fig. All modern CPUs require a heat sink. CISC CPUs are usually built into a system which has a heat sink. heat sink synonyms, heat sink pronunciation, heat sink translation, English dictionary definition of heat sink. n. 1. Basic heat sink heat transfer principle. Heat sink. A CPU fan works in conjunction with a heat sink to prevent this. 6 Heat Sink Types (By Manufacturing Process) Each heat sink manufacturing process has its own advantages and drawbacks. Nearly all computers have heat sinks , which help keep the CPU cool and prevent it from overheating. How does the Heat Sink Calculator Work? Define heat sink. This tool is designed to calculate junction temperature of an electronic device (typically power devices) given four parameters: the maximum ambient temperature, the device's junction-to-package thermal resistance, the thermal resistance of the heat sink… It's easier to clean a heat sink on a desktop PC than it is to clean on a laptop, but you may be able to find a tutorial on how to get at the heat sink on even the most complicated laptop.
