A conventional thermosyphon (CT) is a wickless heat pipe
which acts as a heat exchange device. The CT is able to transfer
heat out of equipment and reduces moisture in air conditioning
units or systems that require a major component to distribute temperature
evenly. To date, there has been little research done on flat
thermosyphon. There are several interesting results from previous
studies of the module design and thermal performance of heat
pipes. Previous results from the study of cross-section-modified
heat pipe showed that reducing heat pipe cross sections led to
the increased performances of heat pipe. For instance, Hussein
et al. [1] conducted an experiment investigating a wickless heat
pipe’s cross-section geometry and filling ratio on the performance
of flat plate solar collectors. Srimuang et al. [2] presented the results
of the effect of working fluid, filling ratio and hydraulics radius
on heat-transfer characteristics of a vertical flat shape
thermosyphon. Payakaruk et al. [3] studied and formulated a correlation
for predicting heat-transfer characteristics of CT. However,
there was no study to confirm that reducing thermosyphon cross
sections which allows performance heat pipes increases. Thus, this
is an interesting point for further research. As mentioned above,
there have been numerous studies reported concerning the effect
of dimensionless parameters and formulated a correlation to predict
heat-transfer rate of VFT’s.
