Abstract

PURPOSE:To manufacture easily a helically coiled heat-transmitting tube having excellent heat transfer efficiency, by cutting a straight tube to form grooves in the outer periphery of the tube and curving it into a helically coild shape. CONSTITUTION:Grooves 3 are formed in the outer periphery of a straight heat- transmitting tube 1 by using a processing machine such as a lathe, and projections 2 are also provided. The processed tube 1 is curved into a prescribed helically coiled shape by rolls. Thus a heat-transmitting tube having large heating surface and high heat transfer efficiency is obtained.

Description

【発明の詳細な説明】 ル式の伝熱盾を製作する方法に関するものである。[Detailed description of the invention] The present invention relates to a method for manufacturing a heat transfer shield of the 3-type heat transfer shield.

。An example of a heat exchanger using helical coil heat exchanger tubes is shown in FIG. That is, a helical coil heat transfer tube 1 is installed in a heat exchanger container, and high temperature gas 2 and low temperature gas 3 flow inside and outside of the heat transfer tube 1, thereby exchanging heat between them. Figure 2 shows details of the heat exchanger tube.

られる。The conventional helical coil heat transfer tube is simply a steel pipe bent into a helical shape. On the other hand, in order to improve the heat transfer performance of heat transfer tubes, some have fins attached to the outer circumference of the tube to increase the heat transfer area, but currently this is limited to straight heat transfer tubes.

ル伝熱管にはフィンは取付けられていない。This is because in the case of helical coil heat transfer tubes, it is difficult to attach fins to helically bent parts, and conversely, it is difficult to attach fins to straight tubes and then bend them helically. Conventional helical coil heat exchanger tubes do not have fins because of the difficulty.

以下本発明による実施例を図面にもとづいて説明する。Embodiments according to the present invention will be described below based on the drawings.

広くなり。FIG. 3 is an external appearance of the helical coil heat exchanger tube, and FIG. 4 is a longitudinal cross-sectional view thereof. The helical coil heat exchanger tube 11 has a groove 13 carved on its outer periphery and a protrusion 12. The groove 13 is formed into a spiral shape. Therefore, the heat transfer area of the heat transfer tube becomes larger.

伝熱効率の高いものとなる。This results in high heat transfer efficiency.

As shown in the figure. In other words, one example is the processing process (a) in which grooves are formed on the outer periphery of a straight heat exchanger tube using a processing machine such as a lathe.
Subsequently, the heat transfer tube is manufactured through a bending step (0) in which the heat transfer tube is bent into a predetermined helical coil shape using rolls. In addition,
