Description

Swirl type heat exchanging tube body manufacturing apparatus {Apparatus for making swirl typed heat exchaning tube}

The present invention relates to an apparatus for manufacturing a heat exchange tube body, and more particularly, to an apparatus for manufacturing a spiral type heat exchange tube body capable of bending a straight pipe in order to manufacture a plurality of heat exchange tube bodies wound in a spiral shape.

Since liquefied natural gas cannot be used immediately because it is in a liquefied state, a vaporizer is required to convert it into gaseous natural gas through heat exchange.

Heat exchangers using heat exchange are used in all fields of industry, including such vaporizers. The heat exchanger is used for the purpose of heating, cooling, or liquefying a working fluid as well as vaporizing a liquid like the above-described LNG.

In most heat exchangers, the key is to increase the contact area and contact time so that heat exchange between the heating medium and the working fluid can occur actively so that heat exchange occurs within a short time.

For this purpose, the heat exchange tube through which the working fluid flows has a structure such as a zigzag type, a spiral type, a coil type, and a spiral type.

The illustrated heat exchange pipe (tube) has a spiral shape in which the radius increases while spirally rotating outward from the center.

However, most of the ones disclosed in the prior art below are for manufacturing a coil-shaped heat exchange tube, so an apparatus and a method for manufacturing a spiral-type heat exchange tube are required.

In the case of the prior art, since most of the straight pipes are bent one by one, as shown in FIG. 1 , an apparatus for bending the heat exchange tube body 10 in which a plurality of heat exchange tubes are stacked at one time has not been proposed.
