Description

Technical Field

[0001] The utility model relates to the technical field of novel petal-shaped spirally wound heat exchange tubes, in particular to a novel petal-shaped spirally wound heat exchange tube. Background Art

[0002] The petal-shaped spirally wound heat exchange tube has a complex petal-shaped structure, which makes the cleaning and maintenance of the heat exchange tube more difficult. Especially when dealing with fluids that need to be cleaned regularly (such as fluids containing particles), its internal structure is not convenient for cleaning. The existing petal-shaped spirally wound heat exchange tube has not dealt with this. For example, a Chinese patent discloses "a petal-shaped spirally wound heat exchange tube", and its application number is: "CN201920831003.8". It is made by pressing a straight tube into a petal-shaped straight tube, twisting and rotating along the tube axis, and spirally winding and deforming it around the winding axis. The tube body has a hollow inner cavity, and a groove is opened on the outer wall of the tube body. The outer wall of the tube body and the groove are provided with a thread structure with a certain spiral angle; the cross-section of the wound heat exchange tube body is petal-shaped, and multiple arcs between the grooves are connected end to end and surrounded in a circle to form a petal-shaped structure; the tube body includes an inlet section, an inlet transition section, a spirally wound section, an outlet transition section and an outlet section connected in sequence; the inlet section and the outlet section are arranged in straight sections; in the spirally wound section, the tube body is spirally wound into a circular or nearly circular cross-section. The above structure makes it easy to use, but when it is in use, its internal structure is too complicated and it is not easy to clean. Especially when dealing with fluids that need to be cleaned regularly (such as fluids containing particles), the tube body is easily blocked, and its use is limited. Utility Model Content
