Abstract

The invention discloses a parallel-tube spiral heat exchange tube. The parallel-tube spiral heat exchange tube mainly solves the technical problems that an existing heat exchange tube is relatively high in manufacturing cost and low in heat exchange efficiency. According to the technical scheme, the parallel-tube spiral heat exchange tube comprises a medium flow tube (11), a diversion spiral plate(12) and an external parallel tube (13); the external parallel tube (13) sleeves the medium flow tube (11); and the diversion spiral plate (12) is arranged between the medium flow tube (11) and the external parallel tube (13) to form an inner tube channel of the medium flow tube (11) and a spiral channel outside the medium flow tube (11). The parallel-tube spiral heat exchange tube is mainly usedfor heat exchange between two substances with different temperatures.

Description

technical field [0001] The invention relates to a tube-side spiral heat exchange tube. Background technique [0002] At present, the heat exchangers perform heat exchange through the heat exchange tubes arranged spirally in the box. Usually, in order to improve the heat exchange efficiency, the length of the heat exchange tubes is increased, thereby increasing the volume and weight of the heat exchanger. Contents of the invention [0003] The purpose of the present invention is to provide a side-by-side spiral heat exchange tube with small volume, less consumable materials, light weight and large heat exchange area. [0004] The technical scheme adopted by the present invention to solve its technical problems is: it comprises a medium flow pipe 11, a guide spiral plate 12 and an outer side pipe 13, and the outer side pipe 13 is sleeved on the medium flow pipe 11, and the medium flow pipe 11 and A deflector spiral plate 12 is arranged between the outer side pipes 13 to for...
