Heat Pipes: Efficient Cooling and Thermal Management

Heat Pipes are used by Engineers alongside Heat Sinks for Thermal Management to transfer heat more evenly and cool efficiently. Typical Applications for Heat Pipes are Military and Telecommunication Equipment, Motor Drives and Rugged Computers whereby integrating a Heat Pipe into your system improves the conduction path of heat from your end application offering improved Thermal Management.

The Heat Pipe is a hollow tube that is sealed with the inner walls lined with a capillary structure. OSCO have a variety of different capillary structure options including Grooved, Sinter or Mesh.

A Heat Pipe offers greater heat transfer in comparison to a solid conductor such as Copper or Aluminium due to their lower thermal resistance.

Typically, there are three divisions in the Heat Pipe including the Evaporator zone which includes the heat input source, the Transporting zone and the Condenser zone where heat is transferred along and removed from the Heat Pipe.

A small quantity of Liquid Fluid such as Water is filled in the Heat Pipe and heat is then applied to the pipe resulting in the liquid fluid evaporating and turning into a gas.

As the vapor travels to the Condenser section (lower temperature) through the Pipe’s hollow core, the heat is dispersed along the Pipe length.

Condensation arises where the temperature is marginally below the temperature of the Evaporation zone. During the condensation process, the vapor relinquishes the heat attained during Evaporation and condenses back to a liquid and absorbed into the wick. The liquid fluid flows back to the higher temperature end of the Heat Pipe where the thermal cycle can begin again.

By combining the Heat Pipe with a Heat Sink, condensation begins at this point with the transfer of heat and a vapor flow pattern is established. The capillary structure within the pipe lining forces the condensation to the source of heat (evaporator) and the cycle is fulfilled.
