“Heat Pipe” – Introduction,Working
Principle,Types,Application
What are Heat Pipes?
Heat pipes are Heat transfer devices. They are Hollow cylindrical pipes filled with a small
amount of fluid that evaporates to produce heat. This heat is then rejected from another end for
its application on industrial processes. For example, it is used in Air Conditioning and
Refrigeration application.
Heat Pipes
Heat pipe working principle:
Heat pipe is generally self-heat recovery devices that is used to transfer heat from one end (heat
injection) to another (destination) with minimum temperature differences and also to pass the
heat across internal surface. Many terms have to be taken into consideration while choosing a
pipe for application on industrial devices. They are manufactured in different shapes such as
round or flat shapes.
Function And Design of Heat Pipe:
They is enclosed under vacuum with a sufficient, preset amount of working fluid. At initial state,
the working water is contained inside the wick lined structure that lines the inside area of the
heat pipe.
When a heat injection, an electronic component, generates heat for input, the fluid/water inside
the heat pipe evaporates in vapor which is known as the evaporator section or bottom end.
