摘要
|
This research utilized 6 mm outer diameter and
3 mm inner diameter glass tubes to manufacture 9
turns Closed-Loop Pulsating Heat Pipe (CLPHP)
with a total length of 1980mm. For achieving the
loop circulation easily, a water cooling system kept at
35 ° C was used as the condenser. The experiment
was conducted to evaluate the thermal resistance
under different fluid filling ratios (20%, 30%, 40%,
50%, 60%, 70% and 80%), and at a series change of
heat inputs (40W, 80W, 120W, 160W, 200W).
Through a digital video camera, the visualization
experiment was carried out to observe the circulation
flow period in the PHP. A styrofoam ball was
designed to put into the tube for a better observation
and a correct estimation of fluid flow direction.
Circulation times and circulation period were
observed and calculated. The results showed that PHP
reached fully circulation under the filling ratio of
60%, 70%, and 80%, at an input power of 200W. The
circulation can be categorized into clockwise
circulation, counterclockwise circulation and
transition circulation status. The CLPHP thermal
resistance was observed to be the least in circulation
flow situation. |
