Novel reinforced heat exchange tube

The utility model provides a novel reinforced heat exchange tube. The novel reinforced heat exchange tube comprises a tube body, wherein the tube body takes the shape of a rectangular tube; splayed grooves are uniformly formed in the surface of the tube body; a column-shaped bulge is formed between each two adjacent splayed grooves. By using the novel reinforced heat exchange tube provided by the utility model, the splayed grooves in the tube body can enhance the heat exchange effect of fluids on the two sides of the heat exchange tube; the tube body adopts a rectangular cross section, and the heat exchange area in a unit volume can be increased compared with a circular cross section, therefore, the heat exchange capacity of the whole heat exchanger tube bundle is increased.
