A laptop computer heat pipe system. A heat pipe is a heat-transfer device that employs phase transition to transfer heat between two solid interfaces. [1]At the hot interface of a heat pipe, a volatile liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface.
A loop heat pipe (LHP) is a two-phase heat transfer device that uses capillary action to remove heat from a source and passively move it to a condenser or radiator. LHPs are similar to heat pipes but have the advantage of being able to provide reliable operation over long distance and the ability to operate against gravity .
The frequency at which vortex shedding takes place for a cylinder is related to the Strouhal number by the following equation: = Where is the dimensionless Strouhal number, is the vortex shedding frequency (Hz), is the diameter of the cylinder (m), and is the flow velocity (m/s).
The ASHRAE Handbook is the four-volume flagship publication of the nonprofit technical organization ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers [a]). This Handbook is considered the most comprehensive and authoritative repository of practical knowledge on the various topics that form the field of heating ...

The oscillating U-tube is a technique to determine the density of liquids and gases based on an electronic measurement of the frequency of oscillation, from which the density value is calculated. This measuring principle is based on the Mass-Spring Model.
Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels using heat tracing cables. Trace heating takes the form of an electrical heating element run in physical contact along the length of a pipe.
A heat pipe typically consists of a sealed pipe or tube at both the hot and cold ends. Heat pipes utilize evaporative cooling to transfer thermal energy from one point to another by the evaporation and condensation of a working fluid or coolant. They are fundamentally better at heat conduction over larger distances than heat sinks because their ...
