The beneficial effects of the utility model are:
(1) oil guide groove in the plates of fin is waveform oil guide groove, and waveform oil guide groove adds oil guide groove length, increases and amasss with air contact surfaces, makes every a slice fin improve thermal energy to oxygen diffusion heat and efficiency.
(2) the middle trapezium structure formed to lateral projections of the plates of fin, can for increasing fuel factor and thermal effect duration.
(3) the oil guide groove upper and lower end parallel communication respectively in the plates of every sheet fin, can be used for preventing oil circuit from blocking, accelerating oil circulation, improve heating effect.
(4) gap between fin is 30 ~ 60mm, can shorten the heat time of oil, improve the fuel factor in the unit interval.
