At the opposite end known as the condenser part, the working fluid/water rejects out its latent heat, which is rejected or produced by an external device i.e. heat sink.
The water then again returns to liquid/fluid form, and the wick structure inside the heat pipe relatively or passively pumps the fluid/water in reverse direction to the evaporator section by using capillary force.
By using this liquid and vapor phases, heat transport mechanism becomes extremely fluent and efficient. Because of heat pipes closed loop design, heat pipes work continuously and passively, gaining a very reliable and passive part of your thermal management system.
Types of Heat Pipes:
• Hot Gas to Air
• Hot Gas to liquid
• Heat Pipe Panel Cooler
• Heat Pipe Dehumidifier
Hot Gas to Air Heat Pipe Exchanger:
The Hot Gas-Air Heat Pipe exchangers consist of different types of tubular gravity, that are supported with finned Heat Pipes and are regulated in a staggered pitch; depending upon the application process.

Hot Gas to Liquid Heat Pipe Exchanger:
The Hot Gas to Liquid heat pipe exchanger consists of Air to Air unit and the only difference is that liquid/water insulated tank is provided to contain media at the condensation section in order to preheat liquid/water.
With special materials used for the construction of the tube, the heat exchanger may be designed to extend up to the range 427℃ to 482℃.

Heat Pipe Panel Cooler (HPPC):
Electrical and electronics operated control panels are made airtight in order to protect our costly electronic and electrical operated devices from dust. The parts inside the electronic devices get overheated which thus leads to failure or malfunction. So the Maniks Control panels coolers are able to extract overheat from inside panel without disturbing the inside environment of the panel.
Heat Pipe Dehumidifier (HPD):
In an air conditioning and refrigeration system, the moisture is condensed out, when the air becomes colder and colder. Therefore by transmitting the heat, from warm air to the cooled outgoing stream supply air, the heat pipe exchangers are responsible to create a double effect of pre-cooling the working air, before it goes to the evaporator section and finally re-heating it immediately. This lowers the heating load, cooling load, and evaporating temperature.
Thus Heat pipe Dehumidifier results in effective energy savings. Typically, for each 1℃ rise in the thermostat setting, there are 3% savings in electricity/energy cost.
Heat pipe applications
• Compact Electronics Enclosures
• Aerospace
• Medical
• Consumer Electronics
• HVAC
1) Compact Electronics Enclosures: Heat Pipe Exchanger provide highly-efficient, compact cooling design for electronic cabinets and enclosures, and it also meets today’s growing demand for thermal power requirements, due to greater miniaturization.
3)Medical: Passive thermal applications (Heat pipes) offer a valuable advantage in medical/hospital devices in terms of saving space, minimizing weight, and reduction of maintenance costs, as they result in less environmental effects as compare to other cooling systems that depend on various technologies such as pumped liquids etc. As there is a constant increase in electronics and electrical operated devices and their need of computing power results in increased heat to be rejected (wasted), and also because of miniaturization is minimizing the required amount of space for thermal management systems, new thermal technologies today like heat exchangers play a very major role in the tomorrow’s manufactured medical devices.
4) Consumer Electronics: Heat pipes heat exchangers are mostly applicable in many days today consumer specific electronic devices such as Power supplies, Laptop and desktop computers, Computer microprocessors, Audio amplifier components, Computer gaming equipment.
5)HVAC: A specially manufactured passive reliable heat recovery HVAC heat pipe will provide you an affordable and effective power recovery system for the hot summer days and your cold winter months continued throughout the year. It also lowers your energy bills and also provides you a rapid return on your initial investment cost.
