The application discloses a sheet type radiator and a
welding method. The sheet type radiator comprises a collecting
pipe, radiating fins and a
spoiler. The
spoiler is welded on both sides of the radiating fin, and the length of the
spoiler is equal to that of the radiating fin. The radiating fin is slidably connected with the collecting
pipe through tile pipes, and the adjacent two tile pipes are clamped. The
welding method is as follows: the two ends of the radiating fin are welded with the tile pipes respectively, the spoiler is welded with the radiating fin, and the two tile pipes on the outermost side are welded with the collecting
pipe after the tile pipes are installed on the collecting pipe. Only one spoiler is welded on one side of each radiating fin, and the two ends of the spoiler are welded with the radiating fin. The
welding area is small, the welding cost is reduced, the production efficiency is improved, the spoiler is welded with the radiating fin first, then the radiating fin is connected with the collecting pipe, the interval between the adjacent two radiating fins is not limited, the welding is convenient, the firmness of the welding mark can be easily detected, and the overall quality of the sheet type radiator is effectively improved.
