Different heat pipe heat sink design can have very different performance and cost implications. Here we compare 1) heat pipes embedded in either aluminum or copper, 2) heat pipes making direct contact with the heat source, and both standard and 3D vapor chambers.
In the battle of two-phase devices, vapor chamber vs heat pipe, there’s no clear winner. Each has attributes that make one superior to the other. This article covers differences in two-phase devices and usage rules of thumb.
In this blog, we’ll break down the design variables of a heat pipe or vapor chamber, discuss each part’s purpose, and examine the implications of making each element thinner: enclosure wall thickness, wick thickness, wick type, vapor space, and internal support structures.

Knowing heat pipe thermal conductivity is important when performing Excel or CFD modeling of two-phase devices integrated into a heat sink assembly. In theory, heat
Heat pipe best practices, usage scenarios, rules of thumb, and heat sink integration tips are presented in the heat pipe design guide.
Our online heat pipe calculator provides the following heat pipe performance data: heat pipe thermal conductivity by diameter, heat pipe carrying capacity (Qmax) by diameter
I recently read an interesting article that explored the practical reasons behind the use of different materials for smartphone enclosures: polycarbonate, glass, and metal. They
