Disconnect the fan The fluid medium is frequently air, but can also be water or in the case of heat exchangers, refrigerants and oil. Computer dictionary definition for what heat sink means including related links, information, and terms. heat sink - a metal conductor specially designed to conduct (and radiate) heat. Use a search engine. Heat sink Definition from Computer & Internet Dictionaries & Glossaries. 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… Nearly all computers have heat sinks , which help keep the CPU cool and prevent it from overheating. Selecting the Heat Sink and Compound. Internet Glossary. A computer motherboard. A heat sink is a metal plate that is specially designed to conduct and radiate heat away from an electrical component. Both a heat sink and a radiator require airflow and, therefore, both have fans built in. that…. What does CPU heat sink actually mean? A component designed to lower the temperature of an electronic device by dissipating heat into the surrounding air. en.wiktionary.org. 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. The mentioned heat sink is part of an experimental setup presented in Fig. The majority of heat … There are a number of different ways to make heat sinks. A heat sink without a fan is called a passive heat sink; a heat sink with a fan is called an active heat sink. ‘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 … Basic heat sink heat transfer principle. Even if you can't find your model, the tutorial for a similar model can be useful. n. 1. T sa is the average temperature difference between the heat sink and the ambient air. How does the Heat Sink Calculator Work? The main objective of this paper is to investigate the effects on thermal performance under axial fan and micro blower airflow for different gap/length ratio heat sinks. The heat transfer efficiencies have been measured for a wide range of heat sink configurations, and their ranges are listed in Table 4. Smartphones or tablets do not have space for heat sinks or fans. 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. translation and definition "heat sinks", Dictionary English-English online. For yet another, it is not 3/4 covered by a massive liquid heat-sink that convectively carries heat across its surface. Active heat sinks are used in liquid cooling system. In doing so, the Cooling fluid from the reservoir was pumped (1) through the flow meter (2) to the heat sink (3). Figure 1: Micro blower-heat sink system for portable computer. Passive Heat Sink. Some also require a fan. Internet Dictionaries. In most of computer processor, a fan is attached just above the heat sink. A heat sink is an object that transfers thermal energy from a higher temperature to a lower temperature fluid medium. 6 Heat Sink Types (By Manufacturing Process) Each heat sink manufacturing process has its own advantages and drawbacks. 1. 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. 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. The correct definition of heat says that it is the total kinetic energy of all atoms or molecules of a substance. #1 – Extruded Heat Sinks. THIS DEFINITION IS FOR PERSONAL USE ONLY. Learn more. heat sink definition: 1. a substance or object that absorbs heat: 2. a device in a computer, mobile phone, etc. Actually, What exactly is a heat? Aluminum-cased wirewound resistors are designed to be attached to a heat sink to dissipate the heat. This heat needs to be removed from the component Heat Sink. After passing the heat sink, the liquid was cooled down in the external heat exchanger (4) and collected in the reservoir (5). It can be in the form of a paste or jelly or a simplealuminum structure which is attached to the heat source. Heat sink definition is - a substance or device that absorbs or dissipates especially unwanted heat (as from a process or an electronic device). For this computer, the duct system can be removed by pressing in on the clips and pulling the duct away from the processor. Types of heat sink Active Heat Sink. The main advantages of natural convection are high Plural form of heat sink. Heat sink definition, any environment or medium that absorbs heat. The CPU fan attaches to the heat sink, pulling air through the fins. Figure 2: Axial fan-heat sinks systems for portable computer. All modern CPUs require a heat sink. A CPU fan works in conjunction with a heat sink to prevent this. Find out inside PCMag's comprehensive tech and computer-related encyclopedia. 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. For the cooling purpose,it incorporates a fan or cooling device. The heat sink for this computer's processor is not visible until this duct is removed from the computer. and fan to cool them down. A heat sink is a device that allows the transfer of heat away from the heat source.
