Abstract
Provided are a tube type heat exchanger and a method of the tube type heat exchanger capable of preventing spiral fins 12 from being deformed. In the tube type heat exchanger and the manufacturing method of the same according to the present invention, the plural spiral fins 12 are disposed in series in the axial direction so as to have edges of the spiral fins 12, 12 spaced apart from each other, and each holder 3 is disposed between the spiral fins 12, 12 and abuts to the outer circumference of the tube body 11.
Claims7
A tube type heat exchanger comprising plural heat transfer tubes disposed in series so as to set axial directions thereof to be parallel to each other, and holders for holding the heat transfer tubes,
- each of the heat transfer tubes including a tube body for flowing fluid therein, and spiral fins formed by disposing fins spirally around an outer circumference of the tube body,
- in each of the heat transfer tubes, the spiral fins being disposed in series in the axial direction so as to have edges of the spiral fins spaced apart from each other, and
- each of the holders being disposed between the spiral fins, and abutting the outer circumference of the tube body.
A method of manufacturing a tube type heat exchanger including plural heat transfer tubes disposed in series so as to set axial directions thereof to be parallel to each other, and holders for holding the heat transfer tubes, each of the heat transfer tubes including a tube body for flowing fluid therein, and spiral fins formed by disposing fins spirally around an outer circumference of the tube body,
- the method comprising:
- a step of cutting fins of each heat transfer tube so as to form a plurality of the spiral fins in series in the axial direction to have edges of the spiral fins spaced apart from each other;
- and
- a step of disposing each of the holders between the spiral fins and bringing the holder in contact with the outer circumference of each of the tube bodies so as to hold the heat transfer tubes.
