Flat-plat pulsating heat pipes (FCLPHPs) have a great potentiality in electronic cooling field and space application. In this investigation, three FCLPHPs (L1, L2, and L3) were built to study the influence of cross section shapes on the heat transfer performance of FCLPHP. One (L1) of them has asymmetric pipe, the others (L2, L3) have symmetric pipes. The results indicate that the FCLPHP L1 has the best heat transfer performance. Compared with the FCLPHPs L2 and L3, the start-up time reduces by 64% and the thermal resistance reduces by at most half respectively.
