A single-tube heat exchanger comprises an inner pipeline and an outer pipeline, the inner pipeline and the outer pipeline are coaxially arranged, the outer pipeline is sleeved with the inner pipeline, a plurality of cooling fins are arranged between the outer pipeline and the inner pipeline and evenly arranged along the periphery of the inner pipeline, each cooling fin comprises an inner fin and two outer fins, and the outer fins are arranged in the outer pipeline. The inner sides of the inner fins are fixedly connected to the outer wall of the inner pipeline, the outer sides of the inner fins are fixedly connected with the inner sides of the two outer fins at the same time, and the included angle formed by the two outer fins connected to the same inner fin is an acute angle. According to the design, the heat exchange area is increased by arranging the heat dissipation fins, a heat exchange medium can uniformly flow through the heat dissipation fins, and the heat exchange efficiency is improved; meanwhile, th
