Is a vapor chamber good for a laptop?

The fans push air through heat sinks to remove the heat. Laptops conventionally use 3-4 heat pipes to move heat – Razer states that the use of the vapor chamber design covers more area and aids in the thinner design. So, is a vapor chamber a good alternate solution to heat pipes in a laptop? The short answer is: Yes.

How effective are heat pipes?

Due to the very high heat transfer coefficients for boiling and condensation, heat pipes are highly effective thermal conductors. The effective thermal conductivity varies with heat pipe length, and can approach 100 kW/(m⋅K) for long heat pipes, in comparison with approximately 0.4 kW/(m⋅K) for copper.

Are heat pipes vapor chambers?

Heat pipes have a high effective thermal conductivity focused along the axis whereas vapor chambers have a more two dimensional, planar heat transfer direction. Most applications require a mechanical load on the heat sink to ensure really good contact to the thermal interface material and device being cooled.

Do Heat pipes work sideways?

A heat pipe is a copper tube with an internal wick structure that is sealed on both ends with a small amount of water inside. Mesh pipes can be used in horizontal and orientations up to 30° out of horizontal. A powder wick heat pipe can also be known as a sintered heat pipe.

How does a laptop vapor chamber work?

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. This is advantageous in situations where you have a massive gas-guzzler of a CPU crammed into a tiny structure such as a laptop.

Do heat pipes work sideways?

How do heat pipes in laptops work?

In the heat pipe, heat converts liquid methanol into vapor, which travels the length of the pipe. At the cool end, which can be made cooler by using a small external fan if necessary, the vapor condenses to a liquid and is wicked back to the hot end.

Are heat pipes expensive?

While they can be designed to mimic the function and performance of a vapor chamber, heat pipes are less expensive and offer increased structural integrity.

Will Heat pipes work upside down?

The fact that the heat pipe works at all in the “upside-down” orientation ( < 0) is due, of course, to the wicking of the condensed fluid against gravity.
