Description
Summary:Heat transfer performance of a flat pulsating heat pipe with single-sided wave plate was experimentally investigated. Influence factors of heat transfer performance were analyzed under the effect of forced air convection cooling conditions, including liquid filling ratio, heating power and inclination angle. The results show that the best liquid filling ratio of pulsating heat pipe is 20%~30% except laid at 0° angle. The effect of inclination angle on the heat transfer performance of pulsating heat pipe is very small, but 90° is relatively the best. Heat transfer performance of heat pipe is poor when it is laid at 0° angle, even loses pulsating effect when liquid filling ratio is low. The main reason is that the backflow of working fluid is in difficulty in this case, which has a lot to do with the design of groove of plate pulsating heat pipe. In addition, heat transfer performance of heat pipe may be undulated when heating power is low, sometimes heat pipe even can't start.
