Aluminium alloy elliptical pipe radiator

The utility model belongs to a pressure resistant type radiator with light weight, which comprises an upper header, a lower header, a plurality of radiating pipes and two inner threads, wherein, one end of the upper header and one end of the lower header are welded with the inner threads connected with a water (steam) inlet pipe and a water (steam) outlet pipe, the faces where the upper and the lower headers are connected with the radiating pipes are respectively a plane, the plane is a big semicircle with radiating flanges after chamfering, and the elliptical radiating pipes with radiating flanges are welded with the upper and the lower headers into a whole. The radiating pipes and the upper and the lower headers of the utility model are made of aluminium alloy pipe materials, and hence, the weight of the utility model is light, and the pressure bearing strength is high; as the radiating pipes and the upper and the lower headers are added with the radiating flanges, the radiating face is enlarged, and the radiating efficiency is improved. The upper and the lower circular headers of the radiator are connected by the elliptical radiating pipes. The utility model has the advantages of unique appearance and model, compact structure, good heat radiation, no resistance to heat convection, and no heat inactive region. The utility model is especially suitable for high buildings.
