Diagram showing components and mechanism for a heat pipe containing a wick Heat pipes keep ground frozen and inhibit water transfer into the open pit during mining activities at Ekati Diamond Mine This 100 mm by 100 mm by 10 mm high thin flat heat pipe (heat spreader) animation was created using high resolution CFD analysis and shows temperature contoured flow trajectories, predicted using a ...
Hydronics (from Ancient Greek hydro- 'water') is the use of liquid water or gaseous water or a water solution (usually glycol with water) as a heat-transfer medium in heating and cooling systems. [1] [2] The name differentiates such systems from oil and refrigerant systems.
Copper/methanol is used if the heat pipe needs to operate below the freezing point of water, and aluminum/ammonia heat pipes are used for electronics cooling in space. The advantage of heat pipes is their great efficiency in transferring heat. The thermal conductivity of heat pipes can be as high as 100,000 W/m K, in contrast to copper, which ...
Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power ...
Cooling system of an Asus GTX 650 graphics card; three heat pipes are visible. Heat dissipation is an unavoidable by-product of electronic devices and circuits. [10] In general, the temperature of the device or component will depend on the thermal resistance from the component to the environment, and the heat dissipated by the component.
The concept resurfaced in the 20th century with hydronic cooling systems in Europe, embedding cool water pipes in structures to absorb and dissipate heat, meeting cooling loads. [ 4 ] [ 5 ] Radiant cooling became more widely adopted in the 1990s, with the implementation of floor cooling. [ 6 ]
The thermosiphon has been sometimes incorrectly described as a 'gravity return heat pipe'. [3] Heat pipes usually have a wick to return the condensate to the evaporator via capillary action. A wick is not needed in a thermosiphon because gravity moves the liquid. [4] The wick allows heat pipes to transfer heat when there is no gravity, which is ...
A heat pump is the central unit for the building's heating and cooling. It usually comes in two main variants: Liquid-to-water heat pumps (also called water-to-water) are hydronic systems that carry heating or cooling through the building through pipes to conventional radiators, underfloor heating, baseboard radiators and hot water tanks. These ...
