Heat Sink Tech Tips

Effective heat sink fin selection is critical in thermal management design, especially when performance targets and production constraints must be balanced. Different applications—from natural convection

Thermal gap pads are soft, elastomeric interface materials designed to bridge significant variances in stack-up height between electronic components and heat spreaders or chassis. Their

This article compares heat sink design for moderately high-power density applications (100 W/cm²), evaluating five designs in terms of performance, weight, and cost. These include solid

An oscillating heat pipe (OHP) is a two-phase thermal device used to move heat over fairly long distances while remaining small and more capable in

Choosing a heat pipe working fluid involves more than matching the operating temperature range or ensuring material compatibility. The heat pipe fluid figure of merit

The vapor chamber manufacturing process varies depending on whether a stamped (2-piece) or tube (1-piece) design is utilized. Each approach offers distinct advantages and potential

The thermal budget defines the maximum allowable temperature rise of a heat source when operating at its maximum thermal design power (TDP). Engineers calculate this

Heat pipe orientation significantly impacts its maximum power carrying capacity (Qmax) and must be carefully evaluated before selecting the heat pipe’s diameter and wick structure.

The distinguishing feature of variable conductance heat pipes (VCHPs) over standard heat pipes is their ability to dynamically regulate the effective condenser area and adapt
