Top Quality HeatPipe Manufactured By Maniks

What are Heat Pipes/Heat Exchangers?

Heatpipe are Heat transfer devices, hollow cylindrical pipes filled with some amount of liquid that evaporates to generate heat. This heat is rejected from another end for application on industrial processes. For example heat pipe is used in Refrigeration and Air Conditioning application.

Heat pipe working principle:

Heat pipes are self-heat recovery devices used to transfer heat from one end (heat source) to another (heat sink) with minimal temperature difference and also to spread the heat across a surface. Many terms have to be considered while choosing a heat pipe for its application on industrial devices. Heat pipes are manufactured in round or flat shapes. Flat heat pipes are simpler to attach to heat dissipating parts while the round shaped heat pipes offer advantages for certain configurations at the condenser end (i.e. heat sink).

Heat pipe function/ Heat pipe design:

A heat pipe is secured under vacuum with a little, prescribed amount of working water. During non-operation, the working fluid is included inside the wick structure that lines the inside diameter of the heat pipe.

When a heat source, an electronic component, generates heat for input, the fluid inside the heat pipe vaporizes which is known as the evaporator section/bottom end.

The fluid vapor immediately spreads to the other end (condenser) of the heat pipe, using the pressure generated by the minimal temperature difference.

At the opposite end, known as the condenser section, the working fluid/water gives up its latent heat, which is rejected or given to an external heat sink.

The fluid then again returns to liquid form, and the wick structure inside the heat pipe passively pumps the fluid/water back to the evaporator section using capillary force.

By using this liquid and vapor phases, the heat transport mechanism is extremely fluent and efficient. Because of it’s a closed loop design, heat pipes functions continuously and passively, creating a very reliable part in your thermal management system.

Types of Heat Pipes:

  • Capillary pumped loop heat pipe
  • Thermosyphon
  • Leading Edge
  • Flat Plate
  • Micro heat pipe
  • Nano heat pipe

Heat Pipe Features & Benefits:

  • Tube material: Copper/ Aluminum
  • Wick structures: Grooved– Low Cost, does not work well against gravity

                                Wire Mesh – Most common method

                           Sintered – Highest performance and cost

  • High thermal conductivity
  • Light weight
  • Fast thermal response

Heat pipe applications:

  • Compact Electronics Enclosures
  • Aerospace
  • Medical
  • Consumer Electronics
  • HVAC

1) Compact Electronics Enclosures: Heat exchangers from provide high-efficiency, compact cooling for electronic cabinets AND enclosures, and it also meet today’s increasing demand for thermal requirements, due to greater miniaturization.

2) Aerospace: Heat pipes are very attractive components in the area of spacecraft cooling and temperature stabilization due to their low weight penalty, zero maintenance, and reliability. Maintaining isothermal structures is an important task with respect to orbiting astronomy experiments under the adverse solar heating.

3)Medical: Passive thermal applications offer valuable advantages in medical devices in terms of minimizing weight, saving space and reducing maintenance costs, as they produce less environmental impacts than other cooling systems that depend on technologies such as pumped liquids. As there is an increase in electronic operated devices and their needed computing power produce increased heat to be dissipated (wasted), and also because of miniaturization is reducing the amount of space for thermal management, innovative/new thermal technologies like heat exchangers play a major role in the tomorrow’s medical devices.

4) Consumer Electronics: Heat pipes are applicable in many consumer specific electronics devices such as Laptop and desktop computers, Computer microprocessors, Audio amplifier components, Power supplies, Computer gaming equipment.

5)HVAC: A well manufactured passive heat recovery HVAC heat pipe will provide affordable and effective energy recovery system during the hot summer days as well as cold winter months and throughout the year. It also lower your energy bills and also provide a rapid return on your initial investment cost.

Heat pipe Advantages:

  • Passive Operation
  • Long Life
  • Zero cross contamination since streams of source and sink are physically separated
  • Minimum Maintenance
  • Compact Size
  • Practically zero back pressure
