Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

Referring to fig. 1 and 3, which show a schematic structural view of a shell-side air cooler in the prior art, as shown in fig. 1, a cooler core is integrally installed in a shell 5, and cooler water is fed into a tube bundle 7 and flows out from a cooling water inlet 14 and a cooling water outlet 15. The cooled gas is led out of the shell, and the water side of the cooler is sealed: the front side is sealed by the tube box where the pass partition 9 is located. The rear side is sealed by bolting through the floating cover 10 and the hook ring 11. Sealing the gas side of the cooler: the front side is connected and sealed with a front fixed tube plate 8 on the shell through a front flange 3 on the cooler core, and the rear side is connected and sealed with a rear fixed tube plate 8 on the shell 5 through a tube box 2.
