Inspection, pack and ship.

A typical heat pipe consists of a copper tube in which the inner walls are lined with a wick structure.

· The heat pipe is charged with de-ionized water and then vacuum sealed. This gives the water a lower boiling point.

· When the heat pipe is heated at one end, the working fluid evaporates from liquid to vapor (phase change).

· The vapor travels through the hollow core of the heat pipe to the other end of the heat pipe, where heat energy is being removed by a heat sink or other means. Here, the vapor condense back to liquid and releases heat at the same time.

· The liquid then travels back to the original end of the heat pipe via the wick by capillary action.
