Radiator module and siphon-type radiator thereof

The invention provides a radiator module and a siphon-type radiator thereof. The siphon-type radiator comprises a transverse pipe, an inclined pipe, a first vertical pipe, a plurality of second vertical pipes, a plurality of fins and a working fluid. The inclined pipe is arranged above the transverse pipe. The inclined pipe is provided with a lower section and a higher section whose position is higher than that of the lower section. The two ends of the first vertical pipe are respectively overlapped and communicated with the transverse pipe and the lower section. The two ends of each second vertical pipe are respectively overlapped and communicated with the transverse pipe and the higher section. The transverse pipe, the inclined pipe, the first vertical pipe and the plurality of second vertical pipes form a return line. The fins are connected to the second vertical pipes. The working fluid fills the return line. According to the invention, air and liquid flow channels can be separated, and therefore the heat
