Top Quality Heat Pipe Exchangers By Maniks

Heat pipe is device that transfers heat using the principles of both thermal conductivity & phase transition so that heat can transfer effectively between two interfaces.Heat pipe is a self-contained passive energy recovery device. A heat pipe can transfer up to 1000 times more thermal energy, than copper, the best known conductor; that too with less than 57℃/mtr temperature drop. One of the amazing features of the heat pipes is that they have no moving parts and hence require minimum maintenance. They are completely silent and reversible in operation and require no external energy other than the thermal energy they transfer. Heat pipes are ruggedly built and can withstand a lot of abuse.

What is Heat Pipe :

Hollow cylinder filled with a vaporizable liquid under vacuum. The Heat Pipe functions as follows

Heat is absorbed in the evaporating section.
Fluid boils to vapour phase.
Heat is released from the upper part of cylinder to the environment; vapour condenses to liquid phase.
Liquid returns by gravity to the lower part of cylinder (evaporating section).

When heat is added to the evaporator section, the working fluid boils and converts into vapor absorbing latent heat.

After reaching the condenser section, due to partial pressure build up, the vapor transforms back into liquid thus releasing latent heat. From the condenser section, heat is taken away by means of water cooling / air cooling with fins etc. The liquid condensate returns to the original position through the capillary return mechanism, completing the cycle. Due to very high latent heat of vaporization a large quantity of heat can be transferred.

Hot Gas to Air Heat Pipe Exchanger :

Typical finned Hot Gas to air Heat Pipe heat exchanger comprise of number of tubular gravity assisted finned Heat Pipes arranged in staggered pitch, depending upon the application. One of the advantages of the Heat Pipe Heat Exchanger is its ability to operate without cross contamination between the two streams.

Use of Gravity Assisted Heat Pipe complies orientation evaporator above condenser for the Heat Pipe Heat Exchanger.

Hot Gas to Liquid Heat Pipe Exchanger :

This heat exchanger resembles Air to Air unit, only difference is liquid/water tank is provided at the condensation section to preheat liquid / water.

Manor heat pipe heat exchanger can recover up to 85% of exhausted thermal energy. However under ideal conditions the thermal efficiency of an economic system ranges between 55 to 70% and saves millions of BTUs year after year.

Manor heat pipe heat exchanger as standard are suitable for air-to air heat recovery for a temperature range of - 10℃ to + 260℃. With special materials of construction for the tube, the exchanger can be designed to extend the range to 427℃ to 482℃

Heat Pipe Panel Cooler ( HPPC ) :

Electrical and electronics control panels are normally made air tight to protect costly electronic and electrical components from dust. Inside components get overheated which leads to failure or mal-function. Control panel coolers extract heat from inside the panel without disturbing inside environment of panel.

Heat Pipe Dehumidifier ( HPD ) :

In an air conditioning system, additional moisture is condensed out, as the air becomes colder and colder. The heat pipe is designed to have one section in the warm incoming stream and the other in the cold outgoing stream. By transferring the heat from the warm return/incoming air to the cold outgoing supply air, the heat pipes create the double effect of pre-cooling the air before it goes to the evaporator and then re-heating it immediately. This lowers the cooling load, evaporating temperature and heating load. Activated by temperature difference and therefore consuming no energy, the heat pipe, due to its pre-cooling effect, allows the evaporator coil to operate at a lower temperature, increasing the moisture removal capability of the air conditioning system by 50-100%.

With lower relative humidity, indoor comfort can be achieved at higher thermostat settings, which results in net energy savings. Generally, for each 1℃ rise in thermostat setting, there is a 3% savings in electricity cost. In addition, the pre-cooling effect of the heat pipe allows the use of a smaller compressor.

Applications Of Heat Pipe :

Waste Heat Recovery from Air Conditioners
Heat Pipe Air Preheater for Boilers
Waste Heat Boilers to Recovery Heat
Heat Recovery at the Kiln Furnace
Spray Drying
