What is a vapor chamber in a cell phone?
A vapor chamber is a cooling solution that improves heat dissipation on performance laptops, PCs, and smartphones. On the latter, they consist of a flat vacuum-sealed metal canister with a small amount of liquid inside.
What is 3D vapor chamber?
Cooler Master showed us its next generation CPU cooling technology at CES 2015, which it calls “3D Vapor Chamber.” Simply put, it’s an evolution of the company’s vapor chamber technology. Vapor chambers for CPU coolers are sealed, flat-ish metal pockets filled with fluid.
How do Vapour chambers work?
A vapor chamber is a planar heat pipe, which can spread heat in two dimensions. The vapor then flows throughout the chamber, creating an isothermal heat spreader. The vapor then condenses on the condenser surfaces, where the heat is removed by forced convection, natural convection, or liquid cooling.
How does a vapor chamber work?
Vapor Chambers are filled with coolant that, when heated, change phases from a liquid to a gas and back again. The vaporized coolant circulates via convection and moves freely through the chamber. The molecules then condense on cold surfaces, dissipate their heat load, and are channeled back to the coolant reservoir.
How do vapor chambers work?
What liquid is in a vapor chamber?
To effectively reduce this undesired effect, the vapor chambers have been proven to be better than the metal spreaders. Generally the vapor chamber is a vacuum container with/without wick structure lining the inside walls that is saturated with working fluid (typically water).
What liquid is used in vapor chambers?
water
Generally the vapor chamber is a vacuum container with/without wick structure lining the inside walls that is saturated with working fluid (typically water). As heat is supplied, the liquid at that location immediately vaporizes, and the vapor rushes to fill the vacuum.
What liquid is in heat pipe?
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 a GPU vapor chamber?
A vapor chamber is a thin, relatively flat plate, that is used to spread heat over a wide surface area. The point of the vapor chamber that is connected to the heat source, such as a GPU, is called the evaporator. When the evaporator is heated, the liquid in the wick evaporates into a gas.
Why do we need a 3D vapor chamber?
The idea is straightforward, and it’s reasonable to expect this 3D Vapor Chamber technology to maximize the cooling efficiency of an air cooler.
How does Cooler Master’s 3D vapor chamber work?
3D Vapor Chambers. The majority of desktop PC vapor chambers have heat pipes welded on top of them to assist in heat transfer, but the 3D vapor chamber technology pioneered by Cooler Master takes this a step further. In a “3D” setup the heat pipes are actually welded into the chamber, streamlining the entire cooling process.
How does a vapor chamber work on a computer?
Vapor chambers rely on pretty much the same concept, but they have a different approach to design. Rather than using separate pipes, a vapor chamber uses its entire body to cool the CPU. Its flat structure allows heat to be transferred evenly through a very small amount of space.
