Split finned pipe sleeve

The utility model provides a split finned pipe sleeve, which consists of a pipe sleeve and fins distributed at the outer side of the pipe sleeve, wherein the pipe sleeve and the fins are divided into two symmetrical half sleeves along the axial direction, the two half sleeves are combined into a whole through screw bolts or clamp buckles or through adopting other modes, and the whole split finned pipe sleeve is arranged on the outer side of a pipe-shaped heat transfer surface of a tubular heat transmitter or the outer side of a single heat pipe of a heat pipe type heat transmitter. The split finned pipe sleeve has the advantages that the processing, mounting, dismounting, cleaning and replacing work of the fins can be simplified, and the corresponding work efficiency is improved. A finned sleeve can be integrally cleaned by equipment such as a cleaning machine after being dismounted. Compared with a traditional method for cleaning the fins, the method adopted by the split finned pipe sleeve has the advantage that the work efficiency can be greatly improved. The split finned pipe sleeve has the advantages that the application range is wide, and the split finned pipe sleeve can be applied to the tubular heat transmitter or the heat pipe type heat transmitter and can also be applied to a coil pipe type heat transmitter and a plate type heat transmitter. When the split finned pipe sleeve is matched with the heat pipe for useto be used, the service life of the heat pipe can be prolonged.
