Can heat pipes be used for cooling?

Heat Pipes are one of the most efficient ways to move heat, or thermal energy, from one point to another. These two-phase systems are typically used to cool areas or materials, even in outer space.

Which are the main applications of heat pipes?

Nowadays heat pipes are used in several applications, where one has limited space and the necessity of a high heat flux. Of course it is still in use in space applications, but it is also used in heat transfer systems, cooling of computers, cell phones and cooling of solar collectors.

What is heat pipe cooling?

A heat pipe is a two-phase heat transfer device with a very high effective thermal conductivity. It is a vacuum-tight device consisting of an envelope, a working fluid, and a wick structure. As shown in the video below, the heat input vaporizes the liquid working fluid inside the wick in the evaporator section.

What is the application use of heat sink in power electronics?

It is used to cool the circuit components by dissipating the excess heat to prevent overheating, premature failure, and improve the reliability and performance of the components.

What is in CPU cooler heat pipes?

Modern CPU heat pipes are typically made of copper and use water as the working fluid. They are common in many consumer electronics like desktops, laptops, tablets, and high-end smartphones.

How do heat pipe CPU coolers work?

The heat pipes are designed to conduct heat from one location to another. In this case, the heat moves to a heatsink that is elevated off of the motherboard, freeing up space for other components, such as RAM. These pipes deliver the energy in the form of heat to the thin metal fins that make up the heatsink.

What are cooling pipes?

Cooling pipe elements are line shaped elements used to describe the influence of cooling fluid flowing through pipes in solid media. Cooling pipes are typically used to reduce the temperatures due to hydration in young concrete.

What is solar heat pipe?

Abstract. Heat pipe solar collectors (HPSCs) are heat exchangers that carry heat based on the phase change of the heat pipe working fluid. It is aimed to increase the operating temperature range of solar collectors by changing the phase of the working fluid in the heat pipe at low temperature.

What liquid is used in heat pipes?

Working Fluids The most common heat pipe working fluid is water for an operating temperature range from 1°C to 325°C. Low temperature heat pipes use fluids such as ammonia and nitrogen. High temperature heat pipes utilize cesium, potassium, NaK and sodium (873–1,473°K).

What is heat dissipation in electronics?

When an electronic device gets overheated, components with thermal ratings less than the temperature developed get damaged. According to Newton’s law of cooling, the heat dissipation rate is proportional to the temperature difference between the body (electronic device) and the surroundings.

Which is better heatsink or fan?

A heat sink is efficient for heat dissipation from electronic components. A fan can move a lot of air, but on its own, a fan is not very efficient for dissipating heat from components.
