Heat sink A heat sink (also commonly spelled heatsink) is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature at optimal levels.

- disperse it into the heat sinks fins, attached to the heat sinks base (Dagan, Barry). The fins provide additional surface area for the heat to travel, allowing the heat to dissipate through the rest of the computer, additionally cooling both the CPU and heat sink simultaneously. However,

Greenhouse effect Greenhouse effect. 1  A representation of the exchanges of energy between the source (the Sun), Earth's surface, the Earth's atmosphere, and the ultimate sink outer space. The ability of the atmosphere to capture and recycle energy emitted by Earth's surface is the defining characteristic of the greenhouse effect.

Orientation effect on natural convective performance of square pin fin heat sinks Aside from the finning factor, the heat sink porosity has a secondary effect on the pin fin performance. The comparison among three orientations shifts in favour of upward and sideward arrangements with raising the heat sink porosity in consequence of reducing the flow resistance.

Bright Hub Engineering Heat islands are parts of the urban landscape where there is a steep temperature variation between that area and cooler surrounding areas. There can be a temperature variation as much as ten degrees. slide 1 of 5. Introduction: We all know that the population of the planet Earth is increasing exponentially.

Carbon Sequestration A carbon sink is a natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period. The process by which carbon sinks remove carbon dioxide (CO2) from the atmosphere is known as carbon sequestration.

Greenhouse Effect Greenhouse Effect. The greenhouse effect refers to circumstances where the short wavelengths of visible light from the sun pass through a transparent medium and are absorbed, but the longer wavelengths of the infrared re-radiation from the heated objects are unable to pass through that medium.reenhouse Effect.

- If that cooling time is too short, the skin will not be of sufficient thickness and strength to hold the part together after ejection from the mold and continued cooling may cause sink marks due to inconsistent and non-uniform shrinkage.

Backwash effect The backwash effect (also known as the washback effect) is the influence that a test has on the way students are taught (e.g. the teaching mirrors the test because teachers want their students to pass). This article is a stub. You can help Elt World Wiki by expanding it.

How Heat Sinks Work 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.

Thermal management of high-power LEDs 1 Shape-Thermal transfer takes place at the surface of the heat sink. 2  Therefore, heat sinks should be designed to have a large surface area. 3  This goal can be reached by using a large number of fine fins or by increasing the size of the heat sink itself.

- The retention of part of the Sun's energy in the Earth's atmosphere in the form of heat as a result of the presence of greenhouse gases. Solar energy, mostly in the form of short-wavelength visible radiation, penetrates the atmosphere and is absorbed by the Earth's surface. greenhouse effect in Culture Expand.

Dufour effect Dufour effect. The Dufour effect is the energy flux due to a mass concentration gradient occurring as a coupled effect of irreversible processes. It is the reciprocal phenomenon to the Soret effect. The concentration gradient results in a temperature change.

- When the temperature at a particular grid point falls to 50 F or less, wind chill will be used for that point for the Apparent Temperature. When the temperature at a grid point rises above 80 F, the heat index will be used for Apparent Temperature.ind Chill: The portion of the cooling of a human body caused by air motion. Air motion accelerates the rate of heat transfer from a human body to the surrounding atmosphere, especially when temperatures are below about 7°C (45°F) (Source).

Carbon sink A carbon sink is a natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period.The process by which carbon sinks remove carbon dioxide (CO 2) from the atmosphere is known as carbon sequestration.Public awareness of the significance of CO 2 sinks has grown since passage of the Kyoto Protocol, which promotes their use as a form of carbon offset.orests are carbon stores, and they are carbon dioxide sinks when they are increasing in density or area. In Canada's boreal forests as much as 80% of the total carbon is stored in the soils as dead organic matter.

What are carbon sinks? A carbon sink is anything that absorbs more carbon than it releases as carbon dioxide. European forests are currently a net carbon sink as they take in more carbon than they emit. In climate negotiations, this temporary reduction of carbon dioxide in the atmosphere is also known as negative emissions. Forest carbon sinks are not an excuse to delay action in reducing fossil fuel emissions.

Greenhouse effect Greenhouse effect The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

CPU cooling Active heat sinks are the primary method of cooling a modern day processor or graphics card. The buildup of dust is greatly increased with active heat sink cooling as the fan is continually taking in the dust present in the surrounding air. As a result, dust removal procedures need to be exercised much more frequently than with passive heat sink methods.

Chilling Effect Law and Legal Definition Chilling Effect Law and Legal Definition. Chilling effect is a term in law and communication that describes a situation where a speech or conduct is suppressed by fear of penalization at the interests of an individual or group. It can affect one’s free speech. Since many attacks rely on libel law, the term libel chill is also often used.
