Title: TORCH PROVIDED WITH FORCED COOLING AIR FILM
Abstract:
A torch provided with a forced cooling air film comprises a wall cylinder (57). Each of the upper end and the lower end of the wall cylinder (57) is provided with an opening, and a combustion chamber (58) is formed in the wall cylinder (57). A plurality of combustors (60) is disposed on the bottom of the wall cylinder (57). The torch also comprises a cooling structure used for cooling the wall cylinder (57). The cooling structure comprises a cooling jacket (64) mounted outside the wall cylinder (57) and a ventilation structure disposed on the wall cylinder (57). A cooling channel (66) is formed by performing partitioning between the cooling jacket (64) and the outer wall of the wall cylinder (57), and the ventilation structure communicates with the combustion chamber (58) and the cooling channel (66), so as to enable forcedly-cooling air flow entering the cooling channel (66) to pass through the ventilation structure to form a cooling air film on the inner wall surface of the wall cylinder (57).
