Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 3-4, the turning structure of the tube bundle of the plate-fin cooler provided by the utility model comprises an upper half part and a lower half part, wherein the upper half part and the lower half part are spliced into a circular structure, the upper half part and the lower half part are connected through a connecting plate 3 and a bolt 4, the upper half part and the lower half part respectively comprise an arc plate 1 and a ring plate 2, the ring plates 2 are fixed around the arc plate 1, two groups of adjusting plates 6 are arranged between the arc plates 1 of the upper half part and the lower half part, and a fastening bolt 8 is arranged between each group of adjusting plates 6.
