A review on the application of horizontal heat pipe heat exchangers in air conditioning systems in the tropics

Recent Advances in Vapor Chamber Transport Characterization for High-Heat-Flux Applications

“…Examples including variable conductance gas-loaded heat pipes for constant temperature control, capillary pumped loops for wickless transport over long working distances, rotating heat pipes in which liquid return occurs by centrifugal force, micro heat pipes, thermal diodes, oscillating heat pipes, and others are described in detail in [1][2][3][4]. Recent reviews summarize research on emerging heat pipe applications [5,6], novel working fluid developments [7], advances in modeling approaches [8,9], and performance of archetypal device geometries, such as loop heat pipes [10,11], micro heat pipes [12], and oscillating heat pipes [13]. A comprehensive summary of all such device types, applications, and analysis methodologies is outside the scope of the current review; instead, the focus is on the burgeoning interest and developments in heat pipes targeted at spreading of very high heat fluxes in ultra-thin form factors, as discussed in the following section…”

Numerical Simulation on Heat Pipe Heat Exchanger: Effects of Different Ambient Temperature

“…Saving energy and protecting the environment is the two major problems facing the national economy [1,2].Heat pipe is a new type of high efficiency heat transfer element. In recent years, due to the shortage of energy and the rapidly development of heat pipe technology, the application of heat pipe heat exchanger in heat recovery of heat energy has achieved good results [3].In order to create a comfortable shopping and working environment, the air-conditioned buildings need for a large amount of ventilation [4][5][6].The heat pipe ventilation heat exchanger is a kind of ventilation equipment, which integrates heat recovery and air purification [7][8][9].Based on the advantages of the numerical simulation software FLUENT, the design and numerical simulation are carried out. In this work, different cases of ambient temperature outside include summer and winter had been studied [10][11].…”

A Review on Heat Pipe for Air Conditioning applications

“…In operation, the working fluid evaporates at the evaporation section and condenses over the other end of the tube as shown in figure 1. The condensed fluid returns back to the evaporator section through the capillary action of the wick or gravitational force in the thermosyphon heat pipes (Y. H. Yau et al, 2010). Simple design and flexibility of heat pipes are important reasons for their extensive applications in industries and air conditioning.…”
