【Abstract】 The paper presented an engineering method, which is used to calculate the current resistance in the course of spontaneous cycle of water in solar powered flat plate water heating. Particularly, selected a sort of spontaneous cycle solar powered water heating system in which with vary diameter of the cycle pipe between one to ten Copper Aluminum complex or ribbed Aluminum tube collectors are arranged one array in parallel connection. Then, according to the calculated results of cycle resistance with the thermo siphon pressure, the paper analyzed and discussed the design of spontaneous cycle solar powered flat plate water heating.更多还原
