1.4 Applications of heat pipe

Due to the advantages of heat pipes, the technology found its applications in many fields of engineering such as:


vi. Electronic cooling [12, 13], etc.

I.Nature of fluid circulation, such as capillary driven, rotating heat pipes, flat

II.Control of heat transfer: They are 'controlled heat pipes', such as variable-

III.Electrostatics-driven heat pipes such as electro hydrodynamic heat pipe.

V.Others including inverse, micro, reciprocating, cryogenic, capillary pumped

gradients along the emitter and collector in spacecraft.

v. Solar energy systems [9, 10] as shown in Figure 3.

i. Spacecraft thermal control [5]: the first test of heat pipe in space was in 1967 [6] and the first heat pipe used for satellite thermal control was on GEOS-B

ii. Component cooling, temperature control and radiator design in satellites. Other applications include moderator cooling, removal of heat from the reactor at emitter temperature and elimination of troublesome thermal

iii. Heat pipes for dehumidification and air conditioning: The heat pipe is

designed to have one section in the warm incoming stream and the other in the cold outgoing stream. By transferring heat from the warm return air to the cold 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.
